64/32 bit switching

I was able to run my D620 Intel in 64 bit mode great, the only thing that didn't seem to work was SleepEnabler, which is prob written for 32 bit.

 

anyway, if you want to try it it's real easy:

 

To select the 64-bit kernel for the current startup disk, use the following command in Terminal:

 

sudo systemsetup -setkernelbootarchitecture x86_64

 

To select the 32-bit kernel for the current startup disk, use the following command in Terminal:

 

sudo systemsetup -setkernelbootarchitecture i386

 

Note: This setting is stored in the /Library/Preferences/SystemConfiguration/com.apple.Boot.plist file and will take effect every time you start up from this disk. If you start up from a different disk, the setting on that disk, or the hardware default, will take effect. ie:

Kernel Architecture

x86_64
