Enabling 64-bit On Mac OS X 10.6.8
I thought that my 27-Inch iMac 2.66GHz Intel Core i5 ran in 64-bit mode by default but I see that it doesn't right now. When I go into the System Profiler and select "Software", I see:
64-bit Kernel and Extensions: No
Yet, when I look in my Activity Monitor, I see Intel (64-bit) under "Kind" running for almost all the processes except for a couple. Is this ever royally confusing or what.
I use a couple of FireWire Interfaces for recording and would like to enable 64-bit mode for the extensions they use (for my M-Audio in particular).
How can I permanently enable 64-bit mode? I could swear that before I updated from 10.6.6 to 10.6.8 a few days ago that I was running in 64-bit mode. Also, does enabling 64-bit mode have any effect on Rosetta?
Is there any disadvantage to running in 64-bit mode (ie: will certain things not work)?
Thanks in advance.
