absolutely awful things that Apple does. If you are using an Apple product
as something other than a disposable consumer product, you will be
disappointed quite often.

work for anything that you would put into the Applications folder. A Mach-O
package can hold code for multiple architectures, and most of the Lion
libraries have 32-bit and 64-bit code. If you run a 32-bit application, it
calls stuff from the 32-bit code in the libraries. This is why mach_kernel
on Snow Leopard had PowerPC code, for example.

I am not sure of whether that works when running the operating system in
64-bit mode, but it is worth a try.

Standard suite? You mean the things like TextEdit?
