It's nice to come from the hackintosh world, thanks to http://www.osxbook.com/blog/2009/08/31/is-your-machine-good-enough-for-snow-leopard-k64/ I will now try to reboot to se if it works hacking the boot.efi file
Because it's kinda stupid having apple blocking features, and snow leopard in 32 bits supports more than 4gb of ram? That's odd, anyway that hack no longer works maybe apple changed something in boot.efi but still boots
The RAM limit is Windows only. Even Tiger supported +4GB RAM. I don't why why there is a limit in Windows but it doesn't apply to OS X. As said above, 64-bit kernel ain't gonna speed up unless your drivers are all 64-bit and you need +32GB RAM which in your case, isn't even possible
Well I've messed around with the boot.efi file and now I have it running at 64 bits mode, but your right, like linux had an option when compiling the kernel to support more than 4gb in 32 bit mode. Anyway it works in 64 bit mode so far so good, no diference in performance, just for fun
If anyone wants the boot.efi modified file just ask
There are some scientific programs that take advantage of 64 bit mode, and they run faster even with only a few GB's of RAM. It's kind of a shame that apple blocks us to 32 bit mode.
Hey i would LOVE to have that boot.efi file!!!
plzzz
plzz
Let me find it and I will re upload it
Edit: What macbook do you have? because boot.efi had a few changes since 10.6.5 and it needs to be re modified.
Boot Efi
I've uploaded the old version because my harddrive crashed just now (damn seagate again). My macbook is still in repairs so test and report back.
I have macbook 7,1 (newest)
10.6.5
I will test and report back.
But those programs don't require a 64-bit kernel. They will still run just fine in 64-bit mode on a 32-bit kernel. Don't complain unless you know what you're complaining about (especially when, if you'd read the whole thread, you'd know what I just said)
64-bit kernel simply allows the kernel itself to address more memory. The catch is, unless it's figuring out much much more memory than a MacBook can hold, there's no point. The idea is to give the kernel more memory to store what it needs to store in order to work with managing the RAM. But unless you've got something like 64 GB RAM, the kernel doesn't need access to more than 4 GB RAM for itself. That's all that booting the 64-bit kernel does. Practically everything else 64-bit works just find with the 32-bit kernel.
Booted into 32,
Damn you Steve...
Well I have no idea what a kernal is, but I know that when I want to edit 50+ megapixel images (not photos), I can't do a FFT on a 32 bit mac but I can on a 64 bit mac... What gives? We're talking about 2-4 GB ram, which should easily handle it.
