Although I don't work with Macs often I've been working with IBM servers and Cisco routers for years, so troubleshooting wacky hardware issues is nothing new for me Thanks for reading this lengthy description! If I leave the system on for a good 10 minutes I can physically feel the heat sinks get warm. Would anyone else have some ideas they'd be willing to share with me? Or is my above hypothesis appear to be correct? So I'm pretty sure that leaves only two logical explanations: either the Video card or Logic board/G5 Processors are bad. The PRAM battery is good, I took a multimeter to it and have another known good battery available. No luck with holding down the OpenBoot or PRAM reset key combination during startup I've done the SMU/PRAM or whatever it's called reset close to a dozen times by now, a few of them waiting 10 minutes between each step just to make sure my impatience isn't affecting it When I start the PowerMac up with no RAM, the light flashes intermittently, so I'm fairly certain it's not a memory issue Once that didn't work, I put only the 1g kit Kingston memory in memory bank 1 and still no luck. I removed all the memory and put just the stock 512mb (2x256mb) RAM chips in there. The white light comes on in the front, all the fans spin up fine, and I can even hold the power button in for a few seconds and it beeps at me.
Now that I have the new power supply in, the Mac starts up, but there's no chime, and no video output. It made a clicking noise and would not power up, so I went ahead and replaced the power supply with a known good one. Shutdown both the MBP and iMac and then try rebooting the iMac as normal from its internal drive that now has Snow Leopard installed.A very long story short I have my cousin's old PowerMac Dual 2.0ghz G5 which she has had since 2003.10.6.8) so that you know for sure it’ll boot the iMac fine

Now install Snow Leopard onto the external drive (i.e.Boot the MBP from the Snow Leopard disc.Connect it to your Mid 2009 MBP with a FireWire cable (once connected it’ll be seen by the MBP as an external hard drive).Boot your iMac into Target Disk Mode by pressing and holding the T key as you startup.The only ways to get around this is to use another disc or do the following: It’s either one that belongs to another Mac or it’s a retail version that’s earlier than 10.6.6. My guess is that you’re not using the grey disc that shipped with your iMac. In other words, the Snow Leopard disc you’re trying to boot from contains a version of Snow Leopard that is earlier than version 10.6.6 (the earliest your iMac can support).
And Yes, it’s trying to tell you something!Ī looping three beeps in between three seconds during startup is your iMac’s way of telling you that the operating system you’re trying to boot into is incompatible with your Mac hardware. Upon checking after Monomeeth's answer I can add that the original Snow Leopard disc I am trying to boot from is indeed a retail version containing 10.6.3.

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.
