[QUOTE="minh.nkim, post: 1871584, member: 406619"] Hello, My macAir mid 2012 can only boot into Windows 10. It cannot recognize OPT to launch start-up disk menu selection. It cannot recognize OPT-CMD-P-R to reset PRAM, thus continuously boot into Windows 10. I tried the following, attempting to reset PRAM: --- ALL FAIL:ED --- 1. OPT-CMD-P-R with built-in keyboard 2. OPT-CMD-P-R with external USB keyboard 3. OPT to launch start-up disk selection, trying to get back into macOS then reset everything from there. Did not work 4. CMD-R to get into recovery mode 3. CMD-OPT-R, was able to launch internet recovery. Was able to download a macOS but the macOS version is not compatible with mid 2012 model. Apple support forum suggested I reset PRAM which is what I am trying now... Would appreciate any pointer how to solve this problem: reset PRAM Thank you Minh [/QUOTE]
