How to detect if a Cocoa application is 32 bit or 64bit ?
+6
A:
In Terminal, type
file ApplicationBinary
If it says Mach-O 64-bit executable x86_64, then it is 64-bit, if it says Mach-O executable i386 then it is 32-bit, etc.

A:
The /Applications/Address Book.app is a directory. To find the actual executable, you need to cd to /Applications/Address Book.app/Contents/MacOS and run the file command on the Address Book executable in that directory (eg. file "Address Book").
