Well, why not? this is a community, after all.

Um, duh on my part. How do you connect a USB-C-only MacBook Pro to an Apple Thunderbolt Display?

If it's a thunderbolt display, the apple USB-C to thunderbolt adapter should work. If you have a displayport cinema dispaly, you need to buy one of the generic adapters:


Note, you can't daisy chain a second adapter to go from mini-diplsayport to vga or DVI.

Thanks. Yeah, can't believe I spaced on considering that. Or I was so exhausted when I placed the order that I got Lighting and Thunderbolt confused again.

Sigh. Now my Mac is just... shutting down? Screen goes to black, gets white Apple logo, I select user and login, it starts to... oops, all black. Log in again.

Zap the pram again, but prepare for the worst.

My "old laptop is trying to kill me by dying itself" has now become "old and new are conspiring to kill me by having Migration Assistant fail in manifold and opaque ways allll weekend" (requires password to connect to Time Machine -- never set a password for it, nothing in Keychain, so can't go that route; Target Disk mode means new laptop sees old laptop, but "Continue" button in Migration Assistant does... nothing; Thunderbolt-cable connected migrations start to work until an hour or so in the "20min left" (which it said for an hour) become "192hr 19min left").

Giving up for now. May have to pay for a tech to come over and sit there on their hourly wage.

Am I missing something obvious? Tom and Dr. Phred have been helpful but I think I stumped them.

Does this (https://support.apple.com/en-us/HT204904) overwrite/delete all your data? That is, if you do this, do you end up with a new OS but none of your apps, settings, documents? It's not clear from this.

What a journey.
Yes, and it's always safe to proceed as if YES...

I don't think that the reinstall macOS option will erase your apps or docs. They wouldn't include instructions on how to erase your startup disk if it happened automatically. It might replace all settings, or just macOS-related settings. I haven't done this myself, though, so please don't take my word as gospel.

Ha, yeah. An Apple support call (over an hour -- she really wanted to get through this) suggested backing up to Time Machine and reinstalling from there. But in the course of that we discovered that turning off File Vault has been going on, a week after I started the process and forgot! So maybe that has something to do with my other issues.

Now, I'm trying to make a recovery disk to boot from on a thumb drive (first problem: where did one of those tiny thumb drives go to, somewhere on my desk???? too small!), but it's not showing up, no matter which USB port I plug it into.

New question: tfw you realize File Vault is _still_ decrypting your internal hard drive, when you told it to start doing that last week, and the time remaining goes from 3h to 4h to more than a day to 11h but never less than 3h -- what do you do? Apple Support docs are either not very helpful or scary (from what I've found: https://discussions.apple.com/thread/6804899).

I don't really have an answer, other than SuperDuper the contents to another disk. I guess that's not practicable, but your computer's behavior over the past month is the equivalent of finding "Redrum" scrawled on your wall.

ddt – November 06, 2017 08:48PM Reply Quote
Oh, THAT'S where that came from. I was wondering!


p.s. Pro tip: if you are trying Migration Assistant from a Time Machine backup and it insists on a password, and you check Keychain Access and the drive and setup _has no password_, what it means is your network or WiFi password (EVEN THOUGH you entered that data when the computer first sets up).

Update -- the Migration Assistant worked with the Time Machine backup, but it threw all sorts of errors, needing password to repair the Library, system extensions blocked -- and then, after over a dozen of dialog boxes... it didn't migrate over my preferences (the Dock didn't have my stuff, the Desktop files weren't there, it didn't know my Mail account info or Bookmarks)... what the hell, man.

If your disk has been going bad for a while, then Time Machine might have copied corrupt files. I'm sorry.

In the ongoing saga... I'll say globally, that my greatest fear is doing something with my current laptop's hard drive and finding I don't have a good backup/can't restore from backup/backup is still wonky.

But I created a flash drive install disk, booted from that, ran Disk Utility, and saw the same errors on my HD as before (different codes but otherwise identical): https://www.reddit.com/r/MacOS/comments/75vci1/running_first_aid_on_boot_disk_apfs_unencrypted/#bottom-comments -- invalid dstream, invalid fstree, can't be fixed.

(Side note: one issue w/ Migration Assistant -- it may in part have been bc my old laptop was taking a week to turn off FileVault that causes migration fails. The other issue seems to be something Apple docs never tell you -- it won't import preferences, Keychain, Desktop folders, etc., if the new/target computer has an existing account name as your old laptop, so you need to delete or rename the new computer's account.)

So it looks like a suggested solution is: reformat my old laptop's internal HD back to HFS+, then back to APFS (https://swissmacuser.ch/solution-fixing-macos-highsierra-apfs-issue-fsroot-tree-invalid-in-beta-17a315i/#.WdopwIZrzOQ). Does this delete my data???

I do not even know what's going on here: https://forums.developer.apple.com/thread/49207

As for my Time Machine backups, in the System Prefs, it says that one has been "Stopping..." for a good long time, and the other is "Waiting to complete first backup". How does one check on freshness, completeness, validity? The Enter Time Machine menu item does show me a today backup on my Desktop but that's not exactly all the info I'd want to know, such as if it's in the process of updating the whole hard drive, etc.

DPBD: Anyone used Disk Warrior or similar on High Sierra? Apple Support is telling me to find something stronger than Disk Utility. https://twitter.com/ddt/status/928054204584701952

I don't think that you can reformat without losing your data on that volume.

If I convert a volume to APFS, can I later revert to HFS+?

You can use Disk Utility to erase an APFS-formatted volume and reformat as HFS+. However, your data will not be preserved when you reformat the volume as HFS+.

What a journey.
I use iPod Nano 3rd Gen(s) all day long. Yesterday mine started flaking out. Won't sync w/iTunes. Corrupt. Pulled another one off the pile, it TOO won't work.
Odd, curious that two now all of a sudden won't sync and both can't be 'fixed', restarted/restored in exactly the same way. I guess I need to replace my $30 iPod with an $1,100 iPhone X is all I can determine. :)

Or buy a used iPhone of much earlier generation; don't get a data plan, and use it as an iPod.
