  1. Wow it works on my MBP Mid 2012 but the Wifi can not connect to a hidden Wireless Network (SSID). Need to unhide it first then connect to the access point. Do you know how to fix this issue? Thanks

  2. Excellent app and it only took a couple hours to do the total install of Big Sur…dun deal! The kext didn’t see the flash drive so I clicked below that message and it kicked in and did the fixes. Wifi worked and the only thing I’ve noticed is on my late 2012 mac mini, it’s runing a tad hotter but performance is awesome. No graphics issues, streams movies fine and so far everything works. Ya dun good, Many Thanks! πŸ™‚

  3. Thank you, upgrade worked like a charm on late 12 mini i7 2.4 GHz quad core. One thing I have noticed not working is restoring from Time Machine, it only gives single finder window and no date/time selection.
