MacOS 15.3 was posted today, which should fix this issue.

I just installed MacOS 15.2 Beta DB2 (build 25D5040f) and it’s been working well for me so far (at least able to reboot without powering off my enclosures). Haven’t had any issues with the ThunderBolt driver but I’ve only rebooted a couple of times.

The current issue is the Thunderbolt driver itself does not always load. So there is still more fixing to do.

Sounds good. When Apple lets you know that they have a fix in a 15.3 beta and you are permitted to confirm, please let me know and I will install the beta to test.

Thanks.

I'm running Version 15.3 Beta (24D5040f) It seems to fix the problem. Now I don't have to turn the raid off and on.

Thanks, we presented yours and a couple other cases to Apple. This is a MacOS bug. It is being investigated, and a fix is promised to be in MacOS 15.3. Hopefully we will be able to post when it is in a 15.3 beta.

At present it appears only to affect the Mac Pro.

Hi,

Someone from Support already asked for my System Diagnostic file so I actually emailed it directly to support. You should have my system report and SoftRAID tech support file from before. However, I don't think SoftRAID is generating any errors. I think the OS simply doesn't see the ThunderBay enclosures. Please let me know if you need anything else.

Thanks.

I need some specific information, as this is a bug we have seen a couple times, but do not have enough info yet to file a bug report to Apple.
When this happens:
save a SoftRAID tech support file
save a System Report
save a System Diagnostic file:
sudo sysdiagnose -f ~/Desktop/
Put all three into a folder.
restart and connect the drives, so you can see your drives.
collect the same set of data.
put them all into a folder and command click, to "compress".
go to filetransfer.io and upload and post the link here. I won't post the link.

I just installed MacOS 15.3 Beta DB1 (build 24D5034f) and the same issue remains for me.

When any ThunderBay enclosure is plugged into a TB3 port and powered on while my 2019 Mac Pro is booting, the enclosure will not be recognized. The enclosures can only be accessed when powered off while booting and then powered on after the Mac is fully booted up.
