When you DO a decide to give it to Apple for a week to fix the problem, do NOT rely on TimeMachine as a backup Mine came back with a new Logic Board, with new SSD, and would not recognize my TM backups at all. (I have 2 separate TM disks) I decided to rebuild from scratch, and pull down most files from Dropbox, but my Github code will get reloaded as needed, and apps installed when I miss them Who has time for another 2 days of downtime trying to work through why the TimeMachine backup was “empty” (it still takes 3TB of disk space)? Not really happy with Apple at the moment

They really need to modernize Time Machine given APFS.

  Unlikely given they've stopped selling the Time Capsule. More likely is replacing it with iCloud.

    I just can't understand why the largest company in the world can't offer both. :/ Apple was seemingly able to do twice as much when they were 20x smaller.

One TimeMachine server or disk can be used by multiple computers. TM distinguish between them using computer name (System Preferences -> Sharing -> Computer Name.) If your computer came back with a different computer name then TM would show you no backups for this machine.

  That sounds like quite the oversight by the TM team.

  They matched I even ran a chmod to remove all old access control data in case it was some internal user id mismatch Still not visible

  So what is the solution? Change the computer name back to the old one? How can you check that, i.e. figure out what TM backups are there for what computer names?

Why did they replace the SSD because of the keyboard? And did they give a warning about that?
- wlesieutre 8y ago
  You can't replace the keyboard, you have to replace basically the whole computer, including the motherboard with the SSD soldered to it. That's why Apple was charging $700 for this repair before the 4-year keyboard warranty program started, and why all these computers are going to be basically worth their scrap value as soon as the keyboard warranty program ends.

    That is incorrect. You have essentially 3 discrete major components that can be replaced separately on the laptops in question. Display - Self-explanatory. Top Case - Keyboard, upper shell, trackpad, battery, touchbar (if applicable). Logic board - SSD (unless a 13" non-touchbar 2016/17 - those have a removable SSD), RAM, CPU. If it has a touchbar, the touchID board gets paired with it and if replacing the Top Case the touchID gets moved over. USB-C ports are on the board on a 2 port model, separate components on a 4 port model. ------------- Replacing a Top Case does require disconnecting every single screw and connection and removing every other component out of the thing and swapping it into the new one. Fans, USB-C ports (4 port models), display, vent/antenna module, logic board, display, etc. It's extremely time consuming to do, even a trained tech isn't going to get that done quickly. That + the cost of replacing Top Cases for keyboard issues is why it was/is so much money.

      Ah, I've been misinformed, thanks for correcting me. It sounds like the SSD shouldn't be affected for a keyboard replacement then. I'm honestly surprised that the cost breakdown has been $600 parts + $100 labor for this, I would have guessed higher on the labor side. I've done repairs on older laptops before, but looking at the instructions from iFixit I don't think I'd try this one. https://www.ifixit.com/Guide/Retina+MacBook+2017+Upper+Case+Assembly+Replacement/104488 https://www.ifixit.com/Guide/Retina+MacBook+2017+Upper+Case+...

I've had success in the past by just mounting the drive and exploring it like a regular drive of data instead of using the Time Machine application. Time Machine creates a bunch of folders (one for each backup event), but just use the one named "Latest". I've read that some people discourage using this technique due to some permissions stuff, but I've never once had problems restoring data from a Time Machine backup using this method, and I've been doing it since 2012.

  Mine are all remote, and are sparsebundle file systems, which I’ve not yet found a way to read in a reasonable way
  - nikisweeting 8y ago
    You can flash a sparsebundle to a local disk, then browse it like a normal filestystem.
    - craz8 8y ago
      I will try that with a backup of my backup to see if I can get my data back up

Something's amiss here. You can use TimeMachine to transfer data from an old computer to a new one. I've done this a few times, and clearly the new one doesn't have any piece of hardware in common with the old one. The last time I did this it was to migrate from a 2015 to 2018 (don't ask - I would have kept the 2015 if it wasn't for my need for 32 GB). If you use the migration assistant, you should be able to pull a TM backup that was done on computer A into computer B. There is something else going on in your setup.
- craz8 8y ago
  I was surprised too! I could find nothing about this online that actually helped in any way Migration during install, migration after install, migration from Recovery system - none of them found anything, and they would hang forever looking for data
  - magnetic 8y ago
    Was your original backup encrypted? Did you log into your iCloud account before restoring? (I don't remember if that's a step that happens prior to restoring in the new Mac setup flow) There could be some credential that needs to be provided in order to find/decrypt a TM Backup. If that key was not available, perhaps the OS/UI doesn't even show you the backup as a restore candidate.

I usually read TM backups from the Terminal but I discovered here is increasing lockdown from SIP since Mojave using a new entitlement dubbed "Full Disk Access". Adding Terminal.app allows for browsing external TM drives (System Preferences → Security & Privacy → Full Disk Access), which definitely came in useful lately. https://blog.wadetregaskis.com/full-disk-access-is-required-to-access-time-machine-backups-in-mojave/ https://blog.wadetregaskis.com/full-disk-access-is-required-...

"It just works"* * As long as Steve is around. I really wonder how much longer Tim Cook is going to be at the helm? Him and Ballmer should be golfing buddies by this point.
