PLEASE READ !!!!! ****** DON'T Believe the Hype -Below - to a point ****** Was able "to successfully" install "update" the word is install... In safe mode managed to install then never loaded during verbose mode throttle issue. Then with FORCE restart severely corrupted by hard drive to the point where disk first aid in both Install DVD and classic could not fix this is Severe!!!! I had to resort to rebuilding the desktop remember that option??? In classic? After doing that I was able to revert AGAIN Back to 10.4.7 the ONLY stable OS for upgrade cards...

In my Opinion this is MacSales and Powerlogix FEBEL attempt for a fix for an OS that apparently is figuring out how to disable these card from working...

Next year I am buying a new Mac and selling my Card on eBay and NEVER refer anyone to MacSales / OWC again.

They have your money but no support...

****** DO NOT INSTALL This Update: OS Freezes during PKEXT install and never does install **** Waste of a Saturday morning re-installing OS 10.4.7 (Only stable version- For Powerlogix Processor Card...

4 months waiting for a update that is even worse than 2.3b5 because with 2.3b5 at least you get an error message instead of your OS Freezing.

If this is sign of how PowerLogix and MacSales supports their products, would think twice about supporting them....
