My older macmini, which i use for iMovie, suddenly rejects every blank disc i put in. Got an external drive burner & it too rejects all discs???? Any ideas?Hello - please provide more information: 1) Model/year Mac Mini; 2) Brand/model of the external optical drive; and 3) OS X installed. Is the external drive a slot-loader or one w/ a tray? For the slot-loader(s) you can gently blow in some compressed air which might correct the issue. Have you rebooted the computer? Finally, have you tried the external unit on another computer?
It's a macmini mid 2011 v. 10.10 yosemite. I had the problem originally with my other macmini 10.4.11 which has an internal burner. It wouldn't recognize discs - i tried many different discs so i thought an exterior burner would solve the problem.
No difference, doesn't recognize the burner. Trying it on the newer macmini 10.10 same thing, doesn't recognize the burner so of course not the disc either. Tried the ext. Burner on my tv. I got recognition, a LG logo floating around but wouldn't play or recognize the dvd. Burner is LG slim portable DVD writer model GP50Nb40 SVC code NB40 ROM VER: 1.00 i have re-booted, it's a tray version.
