Warning about macOS 12.0 Monterey
I’m running into a pretty severe problem with my external USB 3.1-connected NVMe drive on macOS 12.0 on my M1 mac; something in the system is causing the drive to get extremely hot (to the point of disconnecting within a few minutes) when there’s no recorded activity going to it, and also while it is connected, Blackmagic Disk Speed Test reports that it’s only capable of around 150MB/sec, which is significantly less than what it usually gets. Which tells me that something in the OS is causing the drive to go under significant load.
I tried disabling Spotlight, both from the GUI and using sudo mdutil -i off /Volumes/storage
, which made no difference.
