I've been forced to roll back to RC3 in order to reliably boot my computer. Otherwise, I have a very good chance of getting stuck at the SystemVersion.plist line. This is somewhat annoying, since RC4 fixed cpu detection for me... but I'd rather have a usable machine and deal with a "2.6 GHz Unknown" cpu. It would be wonderful if someone could fix this.
(Triple booting OSX 10.5.8, OSX 10.6.2, and Win7- use 10.5.8 daily. Problem only occurs on my Leopard install, and often occurs after booting into Win7. Sometimes is able to be fixed by booting to SL, then back to Leopard (
). Otherwise, any RC3 boot cd gets me back in, and can boot itself thereafter.)
