Hi Everyone,
I am a new member and read with interest the previous posts on this topic on Leopard.
Having been an OSX 10.4 user I upgraded to Leopard without any problems. That was 10.5.1. Then the update for 10.5.2 arrived via the Software Update, which I installed. Also no problem, but when 10.5.3 arrived in the Software Update, I installed it just as before, however this time it knocked my system, a Dual 1.8GHz (separate processors model) for "6"! After the update it would start up and the power supply just switched of while the gray Apple logo and spinning cog where on screen. To cut a long story short having removed and re-installed hardware, tried to re-install the software, but it still switched off while booting from the OSX CD, I discovered that the firmware had somehow become corrupted. I discovered this as I had also lost one of my PCI slots - slot 4. Pressing the SMU button and clearing PRAM helped, but did not restore the PCI slot detection and the card in it. I found the only solution was to remove the lithium battery and disconnected the power cord for about 2 hours. After refitting the battery and powering up, the PCI slot 4 was now OK and I manually downloaded 10.5.3 and installed it from the hard drive and it went in this time without a problem. So it would seem that it might be a better option for all those who suffer upgrade problems to do it this way instead of using the Software Upgrade option, which is fine for minor software upgrades which do not involve the OS.
Hope this helps
Philip
