I have searched several places where there are similar discussions but most of them are on high level hardware requirements. It seems that there is a kernel issue due to which I cannot upgrade - so please help me figure out 2 key questions with regards to upgrading.
My system's hardware and software details are as follows:
Model Name: MacBook
Model Identifier: MacBook3,1
Processor Name: Intel Core 2 Duo
Processor Speed: 2 GHz
Number Of Processors: 1
Total Number Of Cores: 2
L2 Cache: 4 MB
Memory: 2 GB
Bus Speed: 800 MHz
System Version: Mac OS X 10.6.8 (10K549)
Kernel Version: Darwin 10.8.0
Boot Volume: Big Brain
Boot Mode: Normal
64-bit Kernel and Extensions: No
From this kb support article, I have a 64 bit processor;
I am running Mac OS X 10.6.8 and majority of the extensions under my software menu are 'yes' - meaning my kernel is compatible to a 64-bit mode, but is currently running in 32-bit mode.
Following this kb advice, I switched my kernel architecture to 64-bit through terminal. But on checking again, it really offers only 32-bit mode (I386 i386)
See Terminal script:
Marceau-2:~ Bee$ sudo systemsetup -setkernelbootarchitecture x86_64
setting kernel architecture to: x86_64
changes to kernel architecture have been saved.
Marceau-2:~ Bee$ uname -a
Darwin Marceau-2.local 10.8.0 Darwin Kernel Version 10.8.0: Tue Jun 7 16:33:36 PDT 2011; root:xnu-1504.15.3~1/RELEASE_I386 i386
Is there a way to switch my kernel architecture to 64-bit so that I can upgrade to OS X 10.7 and then to Mountain Lion? I went to the apple store in person, but the staff wasn't able to help. I am a big fan of my Macbook 3.1 and want to be able to upgrade its OS alongwith understanding how it works - I would very much appreciate if you could point me in the right direction:
- From this ars technica article, it seems the key challenge is overcoming the hurdle of kernel not being 64-bit; so how can I make my kernel compatible or upgrade it?
- Once I have done that, I plan to upgrade RAM to 4GB so that I can run Mountain Lion. Is that the only hardware upgrade I require?
Thank you very much in advance!
