Had some issues last night and had to reformat my drive(had everything backed up) and reinstall OSX from my recovery CDs. It installed 10.4.5. Apples website says that the 10.4.11 update is for 10.4.6+, but I was running 10.4.11 before. Or could I install this(10.4.6 update): http://support.apple.com/kb/HT2200?viewlocale=en_US and then the 10.4.11 update? Thanks for the help.
