family1232009 Posted August 9, 2022 Share Posted August 9, 2022 (edited) I successfully installed Monterey on my old Optiplex 755, everything works except mouse/keyboard hotplug. ACPI is from https://github.com/denskop/Dell-Optiplex-755-macOS When I unplug my usb mouse/keyboard and then plug it into the same port, it doesn't work although USB flash drives are detected. If I remove the flash drive and then plug it into the same (or any other) port, then it works. I tried making a USB map via USBMap but that didn't work. I also tried Injector.kext from denskop's github but that didn't help either. USB mouse and keyboard still not detected after reconnecting. Catalina + Clover 5121 from github works fine. Dell Optiplex 755 MT, Xeon X3363, GT 640, OpenCore 0.8.3.
