64-bit on my MAC PRO?
So I just found out about 64-bit on my early 2008 Mac Pro 3.0, quad core, 12 GB RAM …I hold down the 4 and 6 number keys on/throughout boot up…but when I do this my trackball (Kensington) and keyboard (Bella) losses all their button functions and their apps say it’s 32-bit, need 64-bit drivers (I have to see if 64-bit drivers even exist).
So I wonder therefore, will every app I have that is 32-bit not run at all or in a weakened state when I boot up in 64-bit; is there a way to tell my Mac to always run 64-bit or do I have to manually do this each boot up; is FCP X only 64-bit therefore have to manually boot up my Mac to 64 each time I start the day (when using FCP X)?
Anything elese we should know re: running 64-bit on MAC PRO’s?
Thanks

Arnie Schlissel posted these links over in the FCPX forum the other day. they should shed some light…
Which Macs support, and do or don’t default to 64 bits:

It’s my understanding that the speed benefit’s of running the 64bit kernel are pretty small, since osx is capable of running your 64bit process on the 32 bit kernel as well as access all your 12GB of Ram.
If your app is written in 64bit and your processors are capable of 64bit it will run in 64 bit regardless of what kernel you have booted. The downside to running the 64bit kernel as you have discovered…all your 32bit apps stop working.
