I have a Macbook 4,1 running Mac OS X 10.7, and I need to install the MESA program, that only works on 64bit machines. Running
uname tells me that my mac is working in 32bit mode, and a quick search online told me that it should be able to run as 64bit, which is what I need.
$: uname -m i386
Following Apple's advice, I tried to get my computer to boot up again in 64bit mode, and verified it with
uname again, to discover I'd failed. So, my question is, can my macbook work in 64bit mode?
