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. Thanks.When I try to boot my Mac I get nothing but strange beeps. Does anyone have any ideas that I can try? Again, nothing has been done to the computer in at least 6 months when I upgraded the RAM. I'm about out of ideas apart from scraping the computer. Here is what I've tried thus far to no avail:ġ) Swapped out the monitors early on since I figured that was my weak link - no changeģ) Tried to boot up from the System Disk - The mini loaded the dvd into the drive, but nothing else (I can't eject the disk so I can put it back)ģ) Start up the computer in target mode connected to another mac - I tried this too, but I never received a chime or the disk show up on the other mac. I don't get anything to the monitor, nor do I get any dings or other start up sounds from the computer. When I turn it on the fan turns, the white power light in the front turns on, and there is a sound that appears to be from the optical drive (rather than hard drive). The computer had been working fine until one day my kids told me that it no longer works. This is the computer my kids use so I don't use it regularly. I have an Intel-based Mac mini mid-2007 (Model A1176).
