MacOS 15.2 DB2 worked great for me and resolved all the issues with my ongoing kernel panics on a 2019 Mac Pro when my ThunderBay 8 and 6 enclosures were attached. However, ever since DB3 (up to an including RC2 and today's GA), I can no longer boot when the ThunderBays are attached. Sometimes, my 2019 Mac Pro will not boot up at all, and sometimes it will boot up but the ThunderBays cannot connect. Unplugging and re-plugging them in doesn't make a difference.
I've only been able to get it work by power cycling and booting up without any of the enclosures attached, and then plugging the enclosures in after my Mac is fully up. Then things seem to be running normally.
This seems similar to the problems I was having before the first beta of MaOS 15.2 (frequent hangs and disconnects whenever the ThunderBay 8 and 6's were attached).
Has anyone else experienced anything similar?
Should not be.
I need a system diagnose, System report and Softraid support file.
system report
Grab a system diagnostic report using terminal:
sudo sysdiagnose -f ~/Desktop/
Putr it into a folder with the rest, compress/archive it with MacOS, and post it using a link from:
I won't post the data.
System report is under System Settings/General scroll to bottom.
the softRAID support file will grab the panic log, so I do not need that.
I just submitted the requested files to filetransfer.io
I emailed you the link using the SoftRAID email support form. Please let me know if you didn't get the files or need more info.
Thanks.

I have the same problem with this OS update 15.2. SoftRAID enclosure needs to be off so the Mac can continue booting process. Then the raid is turned back on and the drives will all mount.
I am presuming this is a Thunderbolt enclosure wityh a 3/2 adapter?
Is this a 2019 Mac Pro?
(this will be fixed in macOS 15.3)
Yes, I have a 2019 Mac Pro with 3 ThunderBay enclosures each directly connected to a separate bus.
The odd thing is that MacOS 15.2 DB2 fixed the previous kernel panics and boot problems. So this is new.
When you say this will be fixed in MacOS 15.3, do you know if the beta has already addressed this? Or did you just mean the plan is that 15.3 will fix this. Do you know what the issue is?
Thanks.

There is no 3/2 adapter. It is a straight active thunderbolt cable. It is a 2019 Mac Pro. connected to a thunderbay 4 Raid. Softraid 8.3.
I won't be able to comment specifically on your question, until there is a public comment somewhere, its the nature of being a developer. But 15.3 is indeed supposed to fix this.
Got it. Can you comment whether the MacOS 15.3 beta will address this? If so, I will try to install the beta when it’s released.
thanks
I saw that MacOS 15.3 DB1 was just released. I normally wait until at least DB2 to install a beta in case new issues are introduced but was wondering if you can comment whether DB1 addresses this issue with ThunderBay enclosures not being recognized when plugged in at boot.
Thanks.
Keep to your pattern. However, note we are limited in public comments on Apple MacOS betas, until a customer reports it, preferably on a public forum like here. So we cannot really say either way, until someone tests it. this can be a bit frustrating, but it is the way it is.

I got a response from Apple they said the build 24D5034f has the fix.
@john-graham
Thanks for posting. This is good to have an Apple confirmation its coming soon
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.
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.
