Somedays ago , i just set some status related to the mac os x 64 bit kernel and Extension. Apparently one of my friend share with me about this. So i decided to do the step by step to make my mac os x system software become 64 bit.
As i know, there are some differences between 32 bit and 64 bit system software in an Operating System included in Mac OS X. One of them is 64 bit boost the performance of our computer. If you want to know more deeply about the differences between 32 bit and 64 bit , you could read this and this .
Below i try to share the step by step for this needed :
- Search via google : boot64.efi , Then download it.
- sudo cp boot64.efi /System/Library/CoreServices/
- cd /System/Library/CoreServices/
- sudo chown root:wheel boot64.efi
- sudo chflags uchg boot64.efi
- sudo bless −−folder /System/Library/CoreServices/ −−file /System/Library/CoreServices/boot64.efi
- Reboot
After that, try to check whether your mac os x system software is 64 bit :
- Via Terminal , please type this command : sysctl hw | grep 64bit . if the result is hw.cpu64bit_capable : 1 , It’s mean your mac os x have been set up to 64 bit kernel system sofware
- Via about this mac , then click on “More info” -> “Software”. If the result is ” 64-bit Kernel and Extensions: Yes” It’s mean your system software is 64 bit.
Sayang nya gw ga punya Mac bro :((. terus klo dah jadi 64 bit. makin kenceng kah kinerja nya? atau malah makin berat ?
😀
makin kenceng bro, lebih mantab pokok nya 🙂
Mas, mau tanya?
Itu berlaku untuk Leopard atau Snow Leopard?
terima kasih
berlaku untuk kedua nya 🙂
when I type on terminal, and shown like this,
uname -m
x86_64
uname -p
i386
lipo -info /opt/local/lib/libiconv.2.dylib
Non-fat file: /opt/local/lib/libiconv.2.dylib is architecture: i386
so, how to fix i386 to x86_64 ?
thank you…
Now, I don’t know exactly how to fix them
but in my mac os x lion now the result is the same when i type “uname -m” and “uname -p”
Thank yu
