    Possible to test drive a different SMBIOS?

    Can I swap my SMBIOS (on a thumb drive so I don't bork my machine, of course) without also needing to sign out of all the iCloud stuff, or is that not an option? I recently got a update on a post that I figured was dead, and I want to try out what the person suggested, which is switching my...

    Mouse LAG/FREEZE/HANG using new RT 5700 XT GPU

    I recently changed my GPU from a GTX 680 to a RT 5700 XT on Catalina 10.15.2. Performance is great, however my biggest concern is a lag/freeze/hang thingy that happens to my mouse. It cyclically freezes every 4 seconds for a short moment. USB doesn't seem to be the issue as it also happens on a...
