Is there an official Apple-supplied list of which Macs (PPC and
Intel) are capable of running 64-bit applications?
No, but I wrote one in a message to this group a while ago. The 64-bit
capable Macintoshes are:
1. All Xserves, except for the very first model
2. All Power Mac G5s
3. All Mac Pros
4. All MacBooks, except for the first edition
5. All MacBook Pros, except for the first edition
6. All MacBook Airs
7. All iMacs, except for the CRT-based models, "iLamps", and the first
two Intel-based models
8. All Mac minis starting with the fifth model (mid-2007)
9. All VMware virtual machines running OS X Server in X86-64 mode
10. All unauthorized Hackintoshes with an X86-64 CPU (Core 2 Duo,
Xeon, Athalon 64, etc.)
Basically, every non-laptop and non-mini released between 2003 and
2005 is 64-bit, and all Macs made since mid-2007 are 64-bit.
So even better, is there a convenient GUI-based way for a user to
check this?
Yes; have them get info on /Applications/Chess.app. If a check box
appears saying "open in 32-bit mode", then they are using a 64-bit Mac.
I don't see anything in "About this Mac".
Well, it does list the CPU type. If the CPU type is Core 2 Duo, Xeon,
or PowerPC G5, then it's 64-bit.
Since there are no running 64-bit processes by default, I can't tell
them to check Activity Monitor.
There are four apps that come with Leopard that are 64-bit that I know
of: Chess, Xcode (which, by default, runs as a 32-bit app), Apache,
and MySQL (Server only).
Also: how can a customer easily choose to run the 32-bit version of
a 32/64 universal app? This may prove occasionally necessary to
accommodate missing QTKit functionality.
Get Info on the app in the Finder. From there, it becomes obvious. :)
