If your Mac is entirely locked up and the above steps won’t work, press Ctrl+Opt+Cmd and the power button at the same time this will reboot your Mac. Select the app you want to close, then click Force Quit (or Relaunch if Finder has frozen), then click Force Quit on the confirmation dialogue box. Hold Option (labeled as Alt on some Mac keyboards) until Quit becomes Force Quit click this.Īlternatively, try pressing Opt+Cmd+Esc to open the Force Quit window. If an app has frozen and quitting it won’t work, Ctrl+click its icon in the Dock, then hover the pointer over the Quit button.

The time needed to cleanly shut down all 6 units on Catalina is about 26 seconds, which is much shorter than when on Big Sur. When I connect these same 6 units to my Mac Pro (late 2013) on Catalina (10.15.7), I have no problems and it cleanly shuts down every time. I'm now (obviously?) thinking that the problem has to do with the number of connected drive enclosures. And I can also cleanly shut down if no units are connected. Btw, it took about 35 seconds to cleanly shut down with 5 units. Only if I add the 6th unit does it panic. If I remove just one of the drive enclosures from the TB chain, I can successfully complete a clean shut down. I'm using M1/Big Sur compatible Pegasus and Softraid drivers that have recently been made available and seem to work OK.īooting up the M1 from a cold start works fine, but if try to shut down with all external drive units connected, after about 40 seconds, the Mini will restart with a panic notification (I copied the beginning part of the panic report below). I connected Mac Mini TB4 port to the OWC TB3 unit, then used an Apple TB3 to TB2 to connect other TB2 units. Two of the enclosures are Promise Pegasus2 R4s (TB2), two are Akitio 4 bay units (TB2) and two are OWC 4 bay units (TB2 and TB3). I also have a similar problem on my new M1 Mac mini on Big Sur (11.1), a 40" 4k external display, and connected to 6 external drive enclosures, all Mac OS Extended (Journaled).
