With netkas’ pcefiv10.1 bootloader, you can boot into 64bi Snow Leopard even on 32bit EFI Macs. So far, it’s not yet known if Apple will enable owners of machines with 32bit EFI to boot into a 64bit kernel in Snow Leopard-final Apple might offer an EFI update, or remove the artificial limitation.
#COPYCATX 4.0 LEOPARD 64 BIT#
PowerMac G5: the first 64 bit personal computer… buy it! You can check your machine’s EFI by running the following command in the terminal: The same applies to MacBooks it might be that Apple is planning on using 64bit as a selling point to drive people to buy MacBook Pros instead of ordinary MacBooks.
The PowerMAc G5 was provided with a specific build of Tiger which had 64 bits support in the Unix layer, allowing the machine to run command line applications in 64 bits. You could also have GUI on top of that communicating with the 64 bits process via IPC. you are embarrassing yourself.ĭoes it limit the number of threads the kernel can handle? Or the memory it can address? So same advise as to Holwerda, don’t talk on something that you don’t understand…. How does a 32 bit OSX kernel manage more than 4 gb of memory, or is the memory management 64 bit? What parts of the kernel stay in 32bit mode? Anything other than device drivers? Read my previous post, i think it is pretty clear.
