Apple Fixes 2023 Mac Pro Hard Drive Issue in macOS Ventura 13.5

Good to hear. Now if they could only fix this issue with USB drives, that'd be great.

Amen. Limited only to Mac Pro or does this bug fix also apply to all other Macs? It would be nice for external enclosures hooked up via USB to make the U mean what it is supposed to be mean again... instead of being a "hit or miss", works-for-some-enclosures-but-not-all proposition.

I have a Mac Studio Ultra and a very important enclosure will not maintain a connection for more than about 3 hours, even without any sleep during that 3 hours. In fact, it "unexpectedly ejects" even when actively transferring files to/from it (so neither end is asleep).

Unhook it from Studio Ultra and hook it to old Intel Macs running macOS BEFORE Big Sur and all is fine again (same cable, same enclosure, same drives, same connection type).

* 2 Old Macs or a PC = stable connection.
* 1 "latest & greatest", "most powerful" Mac = unexpected ejections within about 3 hours.

I know this is not a problem for everyone: some enclosures (including some of my own, including one from the same brand) work just fine. But I'm far from the only one with this problem (many threads about this, identifying many different enclosures with this issue). And I've tested enough to feel very confident that this is a bug(s) in macOS (so please fans/ADF: no "redirection" posts trying to blame enclosure, cable, firmware, etc. Been there, tested through ALL of that more than a few times). Hopefully this fix for Mac Pro is actually a fix for all Macs.

I'd love to see some people not enjoying this same bug (too) chime in that this update resolved it for their (not Mac Pro) Macs.

Nice typos with MacOS version, it’s suppose to be 13, not 12.

[HEADING=2]If you see 'disk not ejected properly' on your Mac Pro (2023)[/HEADING]
If an internal SATA drive unexpectedly disconnects from your Mac Pro, update to macOS Ventura 12.5 or later ('https://support.apple.com/kb/HT201541').

Certain models of internal SATA drives might unexpectedly disconnect from your computer after your Mac wakes from sleep. This can occur if your Mac automatically goes to sleep or if you manually put your Mac to sleep.
To resolve this issue, update to macOS Ventura 12.5 or later ('https://support.apple.com/kb/HT201541').

This the most Apple story ever.


* $7000 machine
* Spinning disk drives
* Took a month and a half to fix

The irony is that on my 2019 Mac Pro, it kernel panics with its various internal PCI-E storage whenever the Mac starts to think about sleeping. Apple has chased the issue with me, sent me a new machine, same problem. I get around it by never having the computer sleep and using a mouse jiggler to keep the Mac from ever thinking of sleeping. Pathetic. Thanks for the vent forum, but glad they are making fixes for the new Mac Pro...

13.5 apparently also fixes SoftRaid ('https://forums.softraid.com/ventura-forum/kernel-panics-softraid-7-5/paged/4/#post-19651') related Kernel panics with M2 Studio and 2023 Mac Pro.
