Finally decided to try the 10.5.5 update on my Hackintosh. Always risky business, doing this sort of stuff; since the desktop is ironically, my primary computer (my real Apple Macbook Pro is just an backup at this point)
The tutorial done by NetKas for upgrading to 10.5.2/3 seems to still apply – and even extends to the Kalyway (which I use) and iAtkos builds of OSx86
I’m reposting the relevant steps here for my own personal reference.
