i'm having strangest thing happen on mac mini (mid 2011).
it's worth, i've upgraded yosemite.
while back, noticed mini wasn't responding ir commands. went check in security & privacy menu under advanced, , sure enough, there no option available disable ir. based on i've read online, means somehow mini has lost ability receive ir signals.
decided try clean install of yosemite bootable usb have, couldn't mini restart while holding down option key.
best mini restart while holding down command + r. via method, apple verified machine, , able download , reinstall yosemite. sure enough, once yosemite reinstalled, mini once again able receive ir codes.
use mini htpc, leave running. however, when restart, lose ir functionality, , looking again in security & privacy, see i've lost mention of ir once again. reinstall yosemite (via command + r, not via option key @ startup), , ir reappears.
restarted computer update, , i've lost ir functionality again. i've gone through sequence 3-4 times, i'm pretty tired of reinstalling yosemite, thought i'd check , see if might have better solution?
yosemite doesn't me on machine, i'd happy reinstall mountain lion (i have bootable usb), can't restart mini when holding down option key, can't this.
might have ideas?
if have third party ssd in there, you'll have problems yosemite.

the prohibitory sign appeared when started macbook pro. read through various options listed on forum , none of them fixed problem. assumed hard drive or corrupt operating system. reinstalled os x. still had problem. finally, swapped out old hard drive new hard drive. still had problem!! when tried old hard drive in spouse's macbook pro (same model) booted fine! when hard drive (which working fine) macbook pro, got prohibitory sign. i'm assuming not hard drive other hardware issue in macbook pro. have insights hardware issue might be? thanks!! huh, that's odd. thought prohibitory sign meant operating system wasn't compatible system trying boot it. try this: whilst turning on system hold command , v keys, system *should* briefly boot verbose , halt @ point prohibitory icon appear. should sort of error/information way luck! ...
