theotheo Posted October 31, 2007 Share Posted October 31, 2007 I'm currently running Leopard on my hackintosh (core2duo). I've read some stuff about Leopard being 64bit. Is there any way of seeing if the kernel and thus the complete system is running in 32 of 64 bit mode? Thanks in advance! Link to comment Share on other sites More sharing options...
riws Posted October 31, 2007 Share Posted October 31, 2007 Simple way is to check Mac OSX Chess game Get Info. If there is 32bit option, you have 64bit System running Link to comment Share on other sites More sharing options...

Is there any way of seeing if the kernel and thus the complete system is running in 32 of 64 bit mode? Thanks in advance! One of the changes I've noticed can be seen in Activity Monitor, if Leopard is running 64 bit the total size of virtual memory is well above 4 GB, something that's only possible with a 64 bit CPU. I've yet to find one of the bundled apps that's actually running 64 bit code though. So far it looks like the apps are compiled for 32 bit and just get a larger address space, although I'm not sure what the benefit of that would be. XCode 3 will easily generate 64 bit code and it executes just fine. Something you can play with if you're a bit technical. The "arch" command can also be used to make sure it's actually selecting the 64 bit code path when executing an app. Link to comment Share on other sites More sharing options...
theotheo Posted October 31, 2007 Author Share Posted October 31, 2007 Thnx for the info guys. If leopard is running in 32bit mode and my cpu is capable of the emt64 stuff. Is there any way to force it in to 64bit mode Link to comment Share on other sites More sharing options...
