Mount Button Grayed out on Disk Utility when I try to connect an External Hard Drive
I have an Apple Hard Drive that I had taken out of my Imac when I upgraded it. I have used it as an external hard drive for the past few years. It works perfectly with my 2014 Imac, but I just bought a new Mac Mini M1 and it won't connect to it. It doesn't show in Finder, but does show in Disk Utility. I can click on the drive and all the buttons are available except for the mount button so I can't access the drive. My Imac is running Catalina and the new Mini is running Monterey.
Mac mini, macOS 12.2
