64bit or 32bit How do i tell which one i'm using?

ugh...this is just freaking weird..

this is what terminal shows:

Code:

Vlad-Southers-Mac:~ Vlad$ ioreg -l -p IODeviceTree | grep firmware-abi
    | |   "firmware-abi" = <"EFI64">
Vlad-Southers-Mac:~ Vlad$

and, this is what system profiler says:

System Software Overview:

System Version: Mac OS X 10.6 (10A432)
Kernel Version: Darwin 10.0.0
Boot Volume: Snow Leopard
Boot Mode: Normal
Computer Name: Vlad Souther’s Mac
User Name: Vlad Souther (Vlad)
Secure Virtual Memory: Not Enabled
64-bit Kernel and Extensions: No <<< WHAT THE HELL ?!
Time since boot: 10:55

what's up with this ?!
Am I using 64bit or 32bit SL ?

You are using 32-bit kernel. The first one just indicates which EFI version do you have

Is this real Mac or Hack ? SL boots in 32Bit by default - but it means only the kernel itself. All app are running in 64Bit ( well, not every one of them, iTunes is 32bit still... ). So don't worry, even if Your kernel didnt boot in 64Bit, You're still using 64Bit apps and Extensions.

hi

same here.

64-bit Kernel and Extensions: No <<< WHAT THE HELL ?!

i would to no how make my kernal boot in 64bit mode..

i found small appes that tells snow leopard to boot 64-bit mode,
right at boot you will see two kernal booting first this one darwin/x86, then darwin/x86_64.
boot time since boot 30secon..

To boot in 64Bit mode :

Real Mac - hold "6" and "4" keys during startup.
Hack - boot with arch=x86_64 flag

Though i didn't try those, so it'd be nice if anyone could confirm that.

i could try that, if someone could just post me the proper code i have to type in the com.apple.Boot
.

vladrxpx · #7 09-23-2009, 04:22 PM

oook... ive edited my com.apple.boot.plist with

Code:

<key>Kernel</key>
	<string>mach_kernel</string>
	<key>Kernel Flags</key>
	<string> arch=x86_64 </string>
	<key>device-properties</key>

nothign happened.. System profiler still says 64-bit Kernel and Extensions: No

any application works faster than on leopard..
Maybe its just showing wrong info

i installed snow leopard and used a dsdt patch.. i still dont know if i have vanilla kernel.. i dont know how to check that.. :/

should you have those spaces around "arch=x86_64"?

No. You shouldn't.

Mine shows:

System Software Overview:

System Version: Mac OS X 10.6.1 (10B504)
Kernel Version: Darwin 10.0.0
Boot Volume: MacHD
Boot Mode: Normal
Computer Name: Max’s Mac Pro
User Name: Max (max)
Secure Virtual Memory: Not Enabled <<< Real Mac's Have this, what is it for?
64-bit Kernel and Extensions: Yes <<<Yes.
Time since boot: 2:01

I should say, mine shows 64-bit Kernel and Extensions: Yes also. I actually did use the button in the app to turn it on initially. I've since added it to the boot.plist in extra. Seems to work just fine.

If you didn't install a separate kernel, then you have the vanilla kernel. I like my vanilla with sprinkles!
