I have no reason to suspect a problem with either the disc (no scratches or other signs of damage and it boots a Mid 2009 MacBook Pro just fine) or the optical drive (it loads other discs fine). To do this I am trying to boot from an original Snow Leopard disc in the SuperDrive. Is my Mac possessed? Assuming not, what is it trying to tell me? Backgroundįor various reasons I want to re-install the original Mac OS X. booted into Apple Hardware Test and no problems found after running extended tests.used a timer to verify it is definitely 3 seconds in between the 3 beeps.
rebooted a number of times and the same exact pattern occurs.checked with Apple KB - About Mac startup tones and this pattern is not listed as an official form of communication.They beep as follows:īEEP BEEP BEEP BEEP BEEP BEEP and it continues until I power off. When I try to boot my Mac I get nothing but strange beeps.
