Tip & How-To about Computers & Internet
There are two ways to set Mac OS X Snow Leopard to run in 64-bit mode.
The first way is quite simple: you just have to hold down "6" and "4" keys while the system is booting up.
The second way is simple as well. You only have to search for a file named "com.apple.Boot.plist" in /Library/Preferences/SystemConfiguration. Open it with Text Editor and edit line 9: where it reads "
Using the second way, Mac OS X Snow Leopard will boot in 64-bit mode whenever you turn on your computer.
PS: 64-bit mode is available just in some machines like MacBook Pro and Mac Pro. To check if your Mac supports 64-bit mode, write the following command in Terminal, again without quotes: "ioreg -l -p IODeviceTree | grep firmware-abi". You will get the answer "firmware-abi" = <"EFI64"> if your system can run in 64-bit mode or "firmware-abi" = <"EFI32"> if not.
