Sylermack Posted January 25, 2018 Share Posted January 25, 2018 I seem to be unable to perform any "Startup key" sequences (select witch OS to boot, resetting PRAM, boot into recovery mode, boot from CD etcetera). I'm using K95 RGB Platinum keyboard directly connected to the computer (iMac Retina 5K, 27-inch, Late 2015) but no startup key commands work. I have tried searching but i can not find any help. I have tried using all 4 USB Ports. I am not using CKB i have not had any luck with it in the past. My Apple keyboard works to use boot key commands. but i want to put it away any ideas? Thanks in advance. Link to comment Share on other sites More sharing options...
