[QUOTE="werby, post: 31820"] OK people, whats the straight dope on how much ram can be allotted to any given application under Panther? On the Adobe discussion boards I've read that there is a 2GB limit to any application, even though G5s support up to 8GB of ram. The story is, apparently, that OSX is actually running 32-bit (not 64-bit) and that 64-bit computing is "years" away. 2GB is a limitation of 32-bit computing because: Quote: "It's a fundamental computer science limit. 2^32 = 4GB, the top bit is usually used to help distinguish system address space from application address space, so applications have 2^31=2GB of address space to work with" OK, well, not that I understand that, but is this the case with G5s? So apple hypes a "64-bit processor" but the OS (and therefore the apps that run under it) can only run 32-bit? So this is pretty deceptive, right? There's certainly no mention of it on Apple's website or discussion boards. Plase comment and/or enlighten me! [/QUOTE]
