    Hey all. Just wondering. How do Universal apps, actually compare in performance as compared to Intel binary apps? Yeah, sure, they're "native" speeds, but surely there must be some performance hit? I mean, it DOES contain two binaries...

    Universal binaries contain BOTH Intel and PPC versions of the executable. They are both in fact separate entities and thus the OS only loads the correct (unless selected in 'Info') binary for the particular application.

    Intel Only -> Intel Only
    UB -> Intel Only and PPC

    Hence only performance hit is in used up hard drive space.
