Having recently purchased a new Mac Pro, I've sold my Dual 2.5 G5 on eBay. I've just re-installed Tiger for the new owner, and had packed everything away ready for shipping, before remembering that I needed to install iLife '06. This requires that 10.4 be upgraded to 10.4.3 or above, and so I ran Software Update and installed the latest combined update - now 10.4.8. All was good until the double re-boot. First one went ok, the second just hung and hung and hung (30 mins+). In the end I pulled the power. I've just run an extended Hardware Test and it's thrown up an error After 10 seconds testing an error code was thrown up: 2 STH/1/2: CPU A AD7417 AD1 It appears it may be a problem with the Logic Board - this is where the test stopped. This doesn't sound good. Does anybody know if this is easily rectified?
