Powered USB stopping iMac from booting up
Just upgraded to the latest version of Big Sur (11.4). Since the upgrade, I can no longer boot up my iMac with my powered USB hub connected to the iMac. To get the iMac to go beyond displaying the Apple logo, I have to disconnect the hub from the iMac, boot the machine and the plug in the powered USB hub which works fine. I had no issues with the previous versions of Big Sur.
Does anyone know how to fix this issue?
thanks
