Looks like macOS 10.12.4 update signed me out of Messages without telling me.
@EggFreckles Me, too.
@EggFreckles The page I linked to says that the behavior changed with 10.12.4. Before that, it was the version that came with your Mac.
@tedsvo Ah, yes, years later I still forget about those buttons that are hidden until you scroll.
@sawlls My understanding is that lets you see the SSD’s own diagnostics but doesn’t itself test the media.
@charlesismcom You now have a choice of versions.
@sawlls Oh, I’ve checked it with Disk Utility. The issue is that I know there are lots of problems Disk Utility can’t detect.
@sawlls Check how?
The new Internet Recovery worked great and got me a macOS 10.12.4 installation that finished booting.
Swift 3.1 update went well. Just a few bridging changes and all tests pass.
@sawlls SSD. Could be, I suppose. How to be sure?
@EggFreckles Yes. Different modifiers for different versions.
Trying the new Command-Option-R recovery to reinstall the latest OS.
And the main Mac, which recently had a clean install, got stuck completing the 10.12.4 update and now won’t boot.
@nriley I thought they had a mail relay to keep your address private. :(
@nriley How do you think they got it?
@lapcatsoftware At least they won’t make you migrate your file system to get the next round of fixes.
@lapcatsoftware For my external drives.
Updated to macOS 10.12. Keychain forgot stuff for FileVault, Tweetbot, Hibari, Arq. And some sort of 1Password problem that it self-fixed.
