Maybe you need to test on another Mac, or bring the mini to an Apple store. its possible the Mini is the issue. I don't know what else to think.

This does not seem to be the issue, as I've tested another OWC Thunderbolt Dock and got the same result. Whatever changed in the macOS update seems to have broken something with multiple connections on the Hub. Here's my setup:

mac mini > Thunderbolt Hub > Port 1: Thunderbay Flex // Port 2: Mercury Elite Pro Dual // Port 3: -

Only one port can be used at a time. The second device will not be recognised no matter the cable or port configuration. This setup was working fine up until the macOS update.

The first issue was SoftRAID seeing the disks but not in SoftRAID format. However, they are actually in SoftRAID format. So it is the application that is unable to read the disks partition maps. (in that earlier support file, where the disks showed up, but had "Apple icons".

Now when the disks are not showing at all, like in that screen capture, that is 100% absoultely, totally, definitively a hardware issue. It has to be the cable (most likely), or perhaps the enclosure. But is a failure for drives not to show up in MacOS, and a hardware failure, as if the disks are "connected" to MacOS, they will show up in Disk Utility (AND SoftRAID)

You said you had multiple enclosures? do they all show the same behavior?

This only occurs when two Raids are connected at the same time. If I attach them one by one, everything is fine. And again it was working fine before updating from macOS 15.5 to 15.6. It’s definitely not unheard of that a .x update broke something in drivers or system extensions.

I’m trying to understand and be as helpful as possible in finding what might have caused this, but it doesn’t feel like it’s even being considered. Sorry to say that, but I’ve been given much better and helpful answers from other companies that seem to care and understand the underlying issue. Has there been any information in the logs I provided? Or is there anything else I can provide to figure out if this is indeed a hardware issue?

  • Manually grant Full Disk Access: choose Apple menu  > System Preferences, click Security & Privacy, then select the Privacy tab. Scroll down and click Full Disk Access, then add the parent process (in this case, SoftRAID)

Because MacOS is preventing the SoftRAID app from accessing the disks directly.

Give SoftRAID full disk access and that will fix this.

Why would all drives show as unmounted, even the internal Macintosh HD, while the machine is running?

Because drives are not showing up. That can only be caused by hardware issues.

That means macOS is not seeing them. It only happens when the hardware has a problem.

I've been using this setup for well over a year. Hardly a coincidence that issues start appearing after upgrading to macOS 15.6. As I said before there are no issues when either (raid) drive is attached individually, but things get messy when multiple Softraid drives are attached at the same time. I've tested all drives individually on two different machines and they show up just fine.

There's been other reports of System extensions (https://www.reddit.com/r/MacOS/comments/1mdv3pq/be_careful_out_there_156_update/) failing after the update, what makes you certain that this is a hardware issue? Why would the drive show up fine and when attaching a second one make it fail?

Nevertheless I will switch cables to rule out other factors.
