Hi

I've recently upgraded my MBP SR 2.4GHz's Tiger to Leopard and is wondering which apps is taking advantage of the newly supported 64-bit platform in Leopard?

Is there a way that I can find out a certain application is running at 64-bit?

Thanks

Darn it..

I ran Xslimmer on my install.

Looks like it removed all of the 64bit code...

Argh.

Mail and iPhoto are not. I don't have keynote to check, but I doubt it is. For some reason I was under the impression that all their software was going to be updated to 64-bit software, with backwards compatibility to run 32-bit. Oh well, everything starts up faster, so I guess it is ok. Safari starts in about 2 seconds.... that's not so bad. Mail starts really fast. iTunes is still pretty slow... probably because I have a lot of media in my library... it takes about 15 seconds. With all my normal stuff running(Mail, Safari, iTunes, Adium, iPhoto) nothing in Activity Monitor shows 64-bit.:apple:

My "kind" column all says intel. The only clue I can find as to whether or not an app is 64 bit is when you get info on an app, most have a checkbox for running in rosetta, chess has a check box for running in 32 bit.

Does it really? I thought I checked that and didn't see a checkbox. That would be very cool.

Xcode is the only one I know of besides Chess. If you look in Activity Monitor, it says which processes are 64 bit, chess lists 64 while xcode does not.

Hopefully apple will update some of their pro apps soon, even something like iMovie or iDVD can probably take advantage.

When I launch chess and look in activity monitor I just get "Intel" not "intel 64"
I have run xslimmer, but it just strips out PPC code, not intel 64 bit code, surely.

The app may have just defaulted to 32 bit operation, you can select it in the Get Info box.

My Xcode defaulted to 32 bit mode, any idea why they'd set it to that?
