| | “firmware-abi” =

which means it is capable of running 64bit OS so did i install snow leopard wrong also im downloading lion right now is there a way of making it 64bit during install this is my first new apple PC since my 2007 Power PC so any help to set this up 64bit in lion would be a great help

Hi,

does this mean that if my mac shows a ‘No’ in the ’64 bit kernel extension’, i cannot toggle between 32 bit and 64 bit OS, or does the ‘No’ show me the current status of the OS?

i am a newbie to Mac, and am having trouble running Win7 64 bit on the Parallel Desktop virtualization package.

It was by default running 32 bit os. Loading of the OS seems to be a little quicker, but I am not sure how stable this will be. I just tried firing up my Apps, Logic, Reason and Serato. They all loaded up, but did not try extensively to start up projects. I plan on installing FCE on here. The question is, is there any real benefit to running 64Bit OS?

I only get beeping (not a single beep though) if i hold the 6 and 4 down for to long, it seems to be a mac version of the default windows beeping when you accidentally depress a key for to long whilst a machine boots, or have a boot problem (I guess windows nicked the idea off of the macs). hope this helps. i have brand new 27″ imac, 2.93GHz i7, MacOSX v 10.6.5

However "Processor Name: Intel Core 2 Duo" so is it 32 bit or 64 bit? In my case
uname -a gives this

“Darwin walkwait-maclt 9.8.0 Darwin Kernel Version 9.8.0: Wed Jul 15 16:55:01 PDT 2009; root:xnu-1228.15.4~1/RELEASE_I386 i386 i386″

This would indicate it is 32 bit.

However “Processor Name: Intel Core 2 Duo”

so is it 32 bit or 64 bit?

You can run the 64 bit kernel it won't hurt anything, but if a plugin requires 32bit it will prevent the 64bit Aperature from loading (I think).

I feel it is still dog slow running Aperture 3 and multiple apps at once. I dropped $2.2k in order to run Aperture 3 better but have not seen much performance increase, especially since my plugins require it to run in 32-bit mode still. So is running the 64-bit kernel safe/stable to do, and if so how? I have the newest Core i7 MacBook Pro and its kernel is running in 32-bit also.
