I've tried this with my M2 MacBook Air and M1 Ultra Mac Studio, and the OWC Thunderbolt Hub seems to be the definite cause.

The accessory causes my Mac to crash randomly while sleeping, although not frequently.

But restarting my Mac always causes it to panic. Shutting down takes a very long time. Booting up to login page takes way longer too, and the process after signing in too.

More often than not, I will get two prompts saying that "your Mac restarted because of a problem", the other asks me to reopen all previously apps or close them due to a Mac issue. These prompts would appear after the Mac tries to sign into an account.

My hub has 3 external hard drives connected to it.

Is this a hardware fault or software fault? Is this a known issue?

I would definitely reach out to OWC. There's really nothing that you (or we) can do. There's a failure in the product that causing your mac to crash. Either get a replacement from them or another model somewhere else

Stop using f Intel only Software by this time in history! If the program is IN TEL only can do this very thing with run away CPU using! So tell the developers to use at LEAST a Un iversal program by this time in MacWorld!

Mmm. I have two OWC TB4 hubs and never had this problem. And I have HDs and SSDs connected to them as well as displays. Perhaps it is a problem with your device?

I was hoping it was a software issue 😩

What do you use for Thunderbolt hub (Thunderbolt ports only)?

How can I tell? I don’t think apps access my hard drives though.

Is yours the small black one with Thunderbolt 4 ports and a USB port?

I have one with 7 external drives and three 4K monitors and have no problem on my Studio Ultra.
