I’m assuming you can’t run Apples security updates when they are offered, rather you have to wait for a patched patch?
TOTALLY depends on the hardware and the install method… Hence my comment previously…
The trick is not making anything any harder for yourself than needs be. So select all your components based on those that are known to work well, rather than having to spend many hours hacking an OSX installation to sort of work. TonyMac’s website is your best friend here.
I built a Hackintosh from scratch, using all components that were known to work well… My Hackintosh basically thinks it’s a Mac Pro, I can do software updates from Apple in the exact same way as you would on a Mac! In fact, my Hackintosh running Snow Leopard has been more reliable than my i7 MacBookPro has on Lion!
My Hardware for anyone interested…
Gigabyte G41M-ES2L Motherboard (most Gigabytes work well, but still worth checking in advance)
Intel Q9400 Core2Quad 2.66GHz Processor
2x2GB DDR2 800MHz OCZ Gold RAM chips
Nvidia 8800GTX Graphics Card (these were standard issue on Mac Pro’s a few years ago so all the drivers are in OSX anyway)
“Hackintosh compatible” wireless card I bought off ebay for about £13, as was advaterised as “guaranteed to work in a Hackintosh”… And it does!
650W Coolermaster Power Supply
1TB Samsung 7200rpm HD
Sony DVD Rewrite drive
The motherboard is the key. Gigabyte are in general the most compatible, but there are still Gigabyte models that don’t work that well. Graphics Card is the next issue, choose a model that has at some point been fitted to a Mac (8000 or 9000 series Nvidia, 5000 and 6000 series ATI all work very well). As far as sound is concerned, I’ve not bothered trying to get the onboard audio to work as I’m always using a USB external interface for mine, but some boards will have audio that works out the box, others will work when hacked, and some you will just have to put another soundcard in (or run external interface like I do). As for other Hackintosh compatible bits… Well, HD’s are pretty much all fine, just choose the one you want. Optical drives can be very choosy though, best bet is to choose a Sony, almost all Sony’s work out the box with no issues. And find a wirless (and bluetooth if you want it) card that is known to work. TonyMac’s website and forum are DEFINITELY is your friend here!
