Becoming a Lord of Time…

…or, how to make Time Machine treat a duplicated and enlarged volume as the original, and continue incremental backups.

It’s not supposed to be possible, but after 3 days of research, and multiple 4-8 hour backup sessions, I’ve cracked it – done something that, as far as I can tell, noone else believes can be done, or has documented how to do. If you follow the instructions here, using only free tools, you’ll be able to do it as well.

The Problem:

You have a Time Machine drive handling backup for multiple drives attached to your system. For example:

Boot / User: 500gb, Photos: 900GB.

Right now, your Time Machine backup is around 1.4TB minimum. On a 2TB drive, that leaves you with 600GB for historical versions of files. Every time you change a file in any way, another copy of the file is added to the Time Machine volume.

Let’s assume your Photos drive is 1TB, and you need to move the contents onto a larger drive before it runs out of space.

You plug in a new 2TB drive, format it with the same name, copy the contents of the Photos drive across, remove the old Photos drive.

You let Time Machine do its thing.

Time Machine will treat the new 2TB Photos drive as a different drive from the original, and perform a full backup of the drive, even though the data on it is identical in every way. Using Carbon Copy Cloner, or Disk Utility’s Restore function will not get around this.

Your Time machine storage now requires: Boot / User: 500GB, Photos (old): 900GB, Photos (new): 900GB, for a total of 2300GB. You’ve now got a backup that’s larger than your 2TB Time Machine volume, and importantly, Time Machine will delete all your historical backups in order to make room for what will effectively be two identical copies of most of your photos.

The Cause:

This happens because Time Machine uses the UUID of the drive to identify it. The UUID is assigned to the drive when it is formatted in Disk Utility, it’s effectively random, and is unaffected by changes to the name of a drive. This means you can change the name of your drive without triggering a full backup, it also means the integrity of your Time Machine backups can’t be effected by temporarily plugging in another drive of the same name, even if the contents are mostly identical.

In general, it’s a safety feature, but as above, it has a serious drawback.

The Solution:

In order to make the enlarged drive behave as a continuation of the old one, you have to fool Time Machine into thinking the new drive is the old one. To do this, you have to copy the data correctly, alter the new drive’s UUID to match the original, then alter the original drive’s UUID so it doesn’t conflict.

Tools You’ll Need:

Note: this is how I made it work – some stuff here may not be totally necessary, but as anyone who used SCSI back in the day knows, superstition is an important part of technology.

  1. A separate bootable MacOS drive / partition where you’ll do all the tasks (to avoid the possibility that your normal system will record what you do in the filesystem events record), and in which you’ve switched off Time Machine. We’ll refer to it as “Tools“. Not the (probably internal) drive you use normally, which we’ll refer to as “MyMac“.
  2. The old (nearly full) drive – “Photos” for this example.
  3. The new larger drive.
  4. A USB thumb drive.
  5. A copy of Shirt-Pocket’s SuperDuper.
  6. A plain text file to act as a scratchpad for copying and pasting things (there’s a pre-formatted version of the whole process below, as a cheat-sheet once you read the process and understand what to do).

Method:

  1. Boot your mac from the normal MyMac drive.
    1. Run a Time Machine backup.
    2. Switch off Time Machine in System Preferences.
  2. Reboot to Tools.
    1. Download and install SuperDuper (to Applications on the Tools drive).
    2. Open Disk Utility
      1. Plug in and format the new larger drive as a standard Mac volume (HFS+ Journalled, case insensitive – make it match the drive you want to clone). The name doesn’t matter.
      2. Plug in and format the USB thumb Drive as a standard Mac volume.
      3. Get info on the old Photos drive, and note down its UUID in your text file. (Depending on the version of Disk Utility you have, you might have to get this from the System Information in About This Mac.)
      4. Select your Photos drive on the left, and use the Restore function to copy it onto the new larger drive (probably called “Untitled”).
      5. Wait some hours while it does its thing. Restore uses block copy which ensures the files aren’t touched or changed by being copied.
      6. Note down the UUID of the new version of Photos on your text file. This is so you can ensure it’s changed later on.
    3. Go to Finder, navigate to where you have installed SuperDuper (Applications).
      1. Right click on SuperDuper, choose “Show Package Contents”, then navigate to Contents / MacOS /
      2. Make sure you can see the exec file SDDiskTool.
    4. Open Terminal.
      1. change directory to the MacOS directory above – you’re going to be using SDDiskTool from the command line, but your comand has to be run from within this directory. The easiest way to do this is (the angle brackets are for actions don’t type them) :
        cd <drag the "MacOS" title icon in the titlebar of the window to here> <hit enter>
      2. Get the UUID in encoded form from the original Photos drive:
        ./SDDiskTool -g <drag old Photos source disk from Finder> <enter>
      3. You’ll see a string of characters returned to the next line, before your command prompt. This is the encoded UUID. Important: Copy those characters to your text file for safe keeping. Be careful selecting them, as they’ll run into the name of your machine at the command prompt.
      4. Set the encoded UUID to the new Photos drive:
        sudo ./SDDiskTool -s <paste the encoded uuid> <drag new Photos target disk from Finder> <enter>
      5. Enter the admin password for your Tools drive system Admin account.
    5. Quit Disk Utility (it has to be relaunched to see the new UUID)
    6. Eject BOTH Photos drives in Finder.
    7. Relaunch Disk Utility and mount the new Photos drive.
      1. Copy the UUID to your text file, and check it matches the original Photos drive version.
      2. Unmount the new Photos drive.
      3. Remount the old Photos drive.
    8. Repeat this process to assign the UUID from the USB thumb drive to your old Photos drive, so that when you reboot to MyMac it won’t confuse Time machine (or, to be super safe physically unplug the old photos drive, do step 9, then reboot to Tools and do this step).
    9. Reboot to MyMac and (eject the old Photos drive if you haven’t changed its UUID) then manually trigger a Time Machine backup – you should be able to tell pretty quickly if it’s worked by the size of the backup that’ll be performed. If it’s the same, or larger than your Photos drive, it hasn’t worked. In which case, stop it, delete the .inprogress file from the Backups.backupdb folder on your Time Machine drive, and start the process from scratch – that’s why you kept the encoded UUID numbers, if you’ve overwritten the old Photos drive UUID with that from the thumbdrive, the encoded value is the only way to assign it. If you open Console, go to System Log, All Messages on the left, then fill in the filter search field on the top right with com.apple.backupd prior to triggering the backup, it’ll tell you how much will be backed up from your various drives. If you’ve done a backup immediately prior to this whole process, then the first backup you do afterwards should be negligible.
    10. If it all worked OK, turn Time Machine automatic backups back on.
    11. If it all goes wrong, and you can’t get the UUIDs to copy, or the copying to stick – my suggestion is to go into the Time Machine history browsing interface when you’re on your whole computer in a Finder window, where you can see all your drives, right click on the photos drive in your most recent level of backup, and delete all backups of photos (they’re safe on your old Photos drive). That will then clear off all your photos backups, meaning that there’s space on the drive to put an entire fresh backup of Photos onto the Time Machine drive, without deleting the historical backups from your Boot / User drive. This is basically where you were going to end up in the first place.

Standard Disclaimer: I take no responsibility for you hosing all of your data and backups doing this. It’s working for me, and I pieced it together and adapted it from bits around the web – mostly relating to how SuperDuper handles working with multiple drives. I suggest doing a practice run with a couple of thumbdrives to make sure you can do it properly.

Cheat Sheet:

1 install Superduper
2 launch terminal
3 cd to inside superduper bundle contents / MacOS
4 ./SDDiskTool -g <drag source disk> <enter>
5 copy encoded uuid
6 sudo ./SDDiskTool -s <paste the uuid> <drag target disk> <enter>
7 enter password
8 unmount disk, quit disk utility, relaunch disk utility and remount disk
9 Write & Check UUIDs
 
 Drive:
 Current UUID: XXXXXXXX-XXXX-XXXX-XXXX-XXXXXXXXXXXX <- The drive you're cloning *to*
 Desired UUID: XXXXXXXX-XXXX-XXXX-XXXX-XXXXXXXXXXXX <- The drive you're cloning *from*
 Encoded UUID: XXXXXXXXXXXXXXXX
 Altered UUID: XXXXXXXX-XXXX-XXXX-XXXX-XXXXXXXXXXXX <- Drive you're cloning *to*
                                                       after the process, should match Desired UUID.

Autopano Giga Wifi Bug

I’ve encountered an interesting bug in Autopano Giga (APG), a product from Kolor, as subsidiary of GoPro.

The Symptom:

Whenever APG is running, it constantly triggers the Mac wifi control software airportd to actively scan for available WIFI networks.

This happens when the system is connected via Ethernet, and not even using WIFI for its network traffic.

This happens despite options to send analytics, and check for beta versions being disabled.

Below, is 10 seconds of captured logfile from OS X’s wifi.log, covering launch, and then immediate quit.

287 lines of logfile in 10 seconds, and that rate continues for as long as the software is running. Once again, this machine is not using WIFI for any actual network traffic, and APG isn’t transmitting any data over this – it’s merely waking up the WIFI system, and telling it to scan the local basestations, and then writing a massive amount of data to multiple logfiles. God only knows what this would do to the battery life on a portable.

Turning off WIFI is the only way to make it stop.

The Cause:

Kolor’s official twitter account suggested to me that this is caused by APG looking for updates.

  • Where’s the setting to turn off checking for updates? I’ve turned off checking for beta versions, that makes no difference.
  • APG attempts to connect to google on quit, which you would only know if you had Little Snitch installed and telling you what apps are trying to phone home behind your back.
  • If it is an update check, why is APG looking for updates, every (approximately) 5 seconds as long as it is running?
  • Why is it powering up the WIFI scan, when the system is set to use Ethernet as its network?

The Horror:

Anachronism

The anachronism of using wood to create a case for a technological item, is perhaps blunted by the use of kevlar in the laminate. It provides scratch protection when placing the phone up or down on a flat surface, especially for the camera lens. A big plus is the minimalist logo on the back – too many cases have the casemaker’s name in huge letters.

While the packaging states it’s for the iPhone 5/5s, it’s also fine with the SE.

Apple Keynote Frustrations

Apple’s Keynote is an app that I’ve enjoyed using for years. It brings a lot of power and polish for a low effort, and reminds me of the thrill I  had when first using Macromedia’s Director 8, upon discovering how much of the app’s abilities were available without using any form of scripting language.

Yesterday, however I discovered a coupe of really serious gotchas that reveal some major limitations with the current software.

Presenter View

Presenter view is an option, which on a multiple display system, allows one screen to show the current slide, and the other screen to show the speaker’s notes, a timer, and the current slide.

A problem surfaces when you want to use your iPad to show your presenter notes, while the presentation itself is being run off a different device. For example, consider a Pecha-Kucha presentation, where you have 20 seconds per slide, 20 slides, auto advancing, and the slides are being run off a central slidedeck on a laptop.

Keynote for iPad won’t show presenter view unless an external display is connected.

Even if you bring along an AppleTV, and set up screen mirroring to it, unless that AppleTV is plugged into a display or projector, you’re out of luck. I’ve heard tell that you can set up Keynote on the iPad to be a remote for keynote on an iPhone, running the presentation on your phone, but that’s still a workaround.

Keynote for iPad needs an update to allow Presenter View to run, without an external display connected – if for no other reason than to allow you to practice your talk.

Mac and iPad

With the launch of iCloud-ified versions of Keynote for Mac and iPad, a lot of features were shed, towards the goal of creating documents that are equally at home in either Mac or iPad. Great, I can get on board with this. The only problem is that it isn’t a complete process, and yesterday, while doing the techtest for a presentation I was going to give, I was bitten HARD by this.

So here is the workspace UI for Keynote for Mac. What’s important to note is that palette on the right, with 3 tabs:

  • Build In
  • Action
  • Build Out

The way it works is that when a slide loads, the Build In settings are run to create the slide, then the Action settings, then Build Out, and finally the Transition effect when leaving the slide itself.

In order to get around the problem above of not having Presenter View available, I created a new slideshow, with a goal of it running in time to the Pecha-Kucha slidedeck, that was essentially what you see in Presenter View.

Since you only have 20 seconds per slide, I wanted a countdown timer for each slide, but rather than using numbers, which are visually distracting, I decided a simple graphical solution would be better. Thus, a blue bar across the top of the slide, and next to the bullet points, which disappears off screen to the right in the former, and downwards past the various bullet points in the latter. This was done with an Action, known as Move, which allows you to set the endpoint and duration of the movement.

Then, with the slide set to auto transition after zero delay, you have a 20 second presenter slide, with time remaining indicator, that then goes immediately to the next slide. Fantastic! Or, so I thought.

When I arrived at the event and did the tech rehearsal, what I discovered is that Powerpoint running on a Mac has a different idea about what 20 seconds is, to Keynote on an iPad, and I had tested my stack against my iPhone’s stopwatch. With Powerpoint set to 20 seconds and no transition time, the iPad about 5 seconds behind by the end of my last slide.

So, no problems, I’ll just edit each of my slides to remove 0.25 seconds from the Move action, that’ll compensate and I’ll be up to speed.

Nope!

While Keynote for iPad knows that the Action stage of the build process exists, and will play the Action stage, it offers no way to create or edit an Action.

As you can see from the video linked on the left here, when you go to add a Build In or Out, you can see that there are actions on the object when you go to look at the Build Order, but there’s no option to adjust it.

A final gripe about the Mac version of Keynote, selecting an image, right clicking and choosing “Replace Image” brings up an iOS style image picker that only shows you the contents of your system’s photo library – in my case, Aperture. It locks you out of accessing your actual filesystem, where for example, you might have kept all the images you’re planning to use within a main project folder in ~/Documents.

This is a symptom of the overall problem I’ve found trying to use the iPad to get actual work done. If everything you do is in a single app, like say, drawing in Procreate, it’s fantastic. But, if your task is assembly, bringing together media from multiple sources, tweaking and adjusting etc, the fundamental nature of iOS – its inability to be file-centric, the way Finder makes a Mac, causes tasks that are mundane and easy, to be like trying to run, while up to your waist in water.

iCould Drive is not a solution – anyone who thinks that the way to move files between devices, is to send them through a server on the other side of the world needs to be sentenced to a year on dialup. iOS needs full peer networking with Macs. It needs the ability to access, and be accessed by filesharing with the same capabilities as the Mac. Finally, it needs to ditch this ridiculous notion that data and documents are contained within apps themselves. I should be able to delete an app, without losing anything I’ve done using that app.

When your Mac Refuses to Sleep.

The Symptoms:

You put your mac to seep, the screen(s) go black, but the machine doesn’t power down its drive(s) and sleep. Pressing a mouse button or keyboard key brings the screen(s) straight back up.

The problem persists through reboots, logouts, changing user accounts, deleting com.apple.PowerManagement.plist, and even doing a full SMC reset.

The Solution:

Go to the Printers & Scanners preference pane, and make sure you haven’t got a printer with a paused print queue, or a printer which isn’t actually connected any more, which you may have accidentally sent a job to, which the system is trying to find.

When iTunes Wi-Fi Sync Stops working.

Sometimes, the ability for iTunes to sync with your iPad, iPhone, or other iOS devices, will simply vanish, and nothing you do seems to solve the problem. The solution may be counter-intuitive, but comes back to the first rule of tech support:

“Did you try turning it off and on?”

There I was, working away, when I noticed the Wi-Fi indicator on my Mac’s menubar suddenly doing the searching for a signal animation. It found the basestation again, and all seemed fine – but then I noticed both my iOS devices had disappeared from iTunes. Odd, I thought, but not without precedent. Sometimes this happens, and switching the Mac’s Wi-Fi on and off will fix the problem.

Alas, this time it didn’t.

Plugging them in via USB and everything worked fine – both devices had the necessary check mark for Sync via Wi-Fi, but as soon as they were unplugged, nothing.

Going through the process of elimination of what worked:

  • The Mac still had network access to the internet via Wi-Fi.
  • The iOS devices still had access to the internet via Wi-Fi.
  • My fileserver / storage app on iOS could still be reached by the Mac.
  • Airdrop still worked between my Mac and iPad.

Most perplexing – in all respects, all the devices seemed to be able to do everything over Wi-Fi except see each other for iTunes Wi-Fi sync.

Here’s the list of the things I tried:

  • Complete shutdown / restart of Mac and all iOS devices.
  • Switching all devices from DHCP to fixed IP addresses.
  • Running the latest Yosemite security patch, and updating iTunes to the latest version (total shot in the dark).
  • Sacrificing a goat.
  • Restoring iTunes .itl files to versions prior to the problem manifesting.

After wasting about 3 hours on trying to solve this, eventually, in desperation, I rebooted the modem, which is also the Wi-Fi basestation.

Bingo! Problem solved.

So, it seems that somehow, part of the modem’s software which allows for service discovery specific to iTunes Wi-Fi sync had failed. This failure only effected those specific functions, allowing everything else on Wi-Fi to continue working, which threw suspicion over on to the Mac where iTunes was running.

Be careful what you wish for…

There’s an idea spreading around the Mac-using world at the moment that Apple should abandon iTunes, and start again from scratch with separate apps handling its various abilities.

There’s one problem with this which gives me pause.

Every change Apple has made to iTunes since version 10, has made the product worse. What has made it worse, is not the overloading of features, but the mindset behind the design of the new features.

UI elements no longer have tooltips. Podcasts have been screwed up, reoriented around streaming and breaking functionality for the download-and-keep model. Lets not forget the disastrous iTunes 11.2 “upgrade” which introduced a new “saved” podcasts feature, which allowed you to protect individual episodes from auto-deletion – and which the upgrade process told you would be applied to ALL of your previously downloaded podcast episodes. That function was faulty, and since iTunes had auto delete after listening defaulted to on, upto half the episodes in many of my stored podcasts disappeared in an instant. Not in the trash, no undo, just gone.

Can’t you just re-download them?

That presumes two things, firstly that bandwidth is free and uncapped, and secondly, that all podcasts keep every episode in their feed forever. Many don’t. Some of my subscriptions have gone offline entirely. The point is, user data is sacrosanct, and deleting it without an explicit command from a user, with an “are you sure” dialog is the greatest sin a piece of software can commit.

This is a symptom of a part of the larger problem Apple has, those who are in charge of the direction of its products are possessed of such immense bandwidth privilege, they seem incapable of designing products for an offline reality. The sheer insanity of using a server on one side of the world, to move a document between two devices a foot apart, or that two devices which can be physically cabled together, can’t share calendar reminders without an internet connection, is hard for me to wrap my head around.

So, given that all the things which are bad about iTunes, are post-version-10 changes to the product, what makes anyone think that an all-new music solution would be anything other than a reflection (and likely a magnification) of the philosophy which created all these ruinous changes?

What’s wrong with iTunes, are the new parts of iTunes, not the presence of what is increasingly becoming “legacy” functionality.

The New Apple Paradigm

It’s time for a bit of recreational Kremlinology regarding Apple’s strategies.

When Intel and Apple brought the Thunderbolt interface into the world, there were a lot of interesting possibilities created. Thunderbolt being essentially the PCI bus on a wire, many peripheral solutions that were previously done with internal cards, could now be created as breakout boxes, which could serve both desktop and laptop users.

Since Thunderbolt is capable of carrying all of the other peripheral busses, one great solution it enabled was Apple’s Thunderbolt display, which could act as a peripheral hub for a laptop. You plug power into the display, and then the display has an upstream cable which branches into thunderbolt, and Magsafe power for the laptop. So with that one cable, your laptop effectively becomes a desktop (and your laptop’s power adapter stays in your travel bag).

My 68 year old mother, who is an accountant, uses this solution. She has a light, compact, 13″ Macbook Air, with which she travels interstate every quarter to work with clients. In her home office she has the big display, keyboard, mouse etc. On the road, the system is light & compact, at home it has screen space for her MYOB Windows VMs, remote desktop sessions with client computers etc.

The new Macbook isn’t set up to do his. It’s only external display options are HDMI and VGA, and with no Thunderbolt due to its sole USB3-C port, arguably, it never will.

It remains to be seen whether this is a repeat of the goof that was the original 13″ Aluminium Macbook (which dropped the firewire of its polycarbonate incarnation, only to regain it in the next revision), or whether this is a new paradigm of less versatile Macs, which have a narrower but deeper usability. By forgoing all the ports that make a laptop able to be both a portable, and desktop, Apple have made a computer that is arguably better when it’s being a portable.

The question is whether this will make its way into the rest of the laptop lineup. If so, I think we can probably say that the paradigm that Apple is heading towards, is this: People who need both desktop and laptop usage scenarios, should be buying a desktop and a laptop, and then using Continuity to move their work state between devices. The net result of more device sales for Apple is obviously just a happy coincidence.

Rotating a .NEF Raw File

One of the problems I’ve had using Apple’s (now end-of-lifed) Aperture photography software, is that it doesn’t make changes to an original RAW file. Everything changed within it is done using versions – essentially metadata – so that you can have a dozen different variants of a file, but only ever have one taking up space on disk.

It’s a great idea, except when your original has a problem, like for example the camera has recorded orientation information that you don’t want applied. Aperture provides no way to alter the RAW file. You can create a rotated version in Aperture, but exporting the RAW will output the original un-rotated edition.

The solution is to use Nikon’s own ViewNX software. It’s ugly as sin, not at all Mac-like, but when you rotate a RAW file in it, the file on disk is rotated, while staying as a RAW.

Then, you have to reimport the image as a new file, and delete the old version. Simply replacing the old one with the rotated version in Aperture’s library won’t show up as having been changed when you re-launch Aperture.

iOS 8 Photos app – DSLR Fail.

With the update to iOS 8, Apple obsolesced the iOS version of iPhoto. Notwithstanding that iPhoto was a paid product, which is made unusable without warning, the replacement has certain issues.

The replacement for iPhoto is an expanded set of capabilities for the Photos app. What it doesn’t have, however, is the ability to view EXIF data for the images, so if you’re using the iPad to triage images in the field, you can’t see any of the technical details of your shots – no aperture, iso, shutter speed or anything. Worse still, when you try to edit images…

Photos can’t perform more than a single edit on an image without it pixelating like this.

These add to the commonly held view that things at Apple are starting to go off the rails, at a systemic, company-wide level. Within Apple’s software efforts, new features are being brought to market before they’re thoroughly ready. More importantly, old working solutions are removed from users’ systems before their replacements are up to the task.
