Finally have my computer where I want it to be - except for upgrading to Windows 7 - been testing that operating system for the last few months though on a custom computer that couldn't run Vista worth a damn (it runs Windows 7 like a dream though - go figure). Rather pleased with it overall and now I want to upgrade my Mac Pro (macpro 2,1 3.0Ghz Xeon Quad) from Vista 64-bit to Windows 7 64-bit. Now having tested the upgrade process on the other computer I really don't think it should be a problem Vista to Windows 7 (that was the RC). But I came across this KB on apple's website http://support.apple.com/kb/HT3920 saying that Apple does not support upgrading to Windows 7 on what I believe is my model of Mac Pro. I'm curious if anyone else had any issues upgrading to Windows 7 from Vista on their Mac Pro, and if so how did you work through your issues?
