In the wake of reports from TUAW and RoughlyDrafted.com that 10.6, also known as Snow Leopard, would be the smallest Apple OS in years, many have been scrambling to figure out how exactly Apple was going to be dropping that much heft from their mainline apps. An especially big loser was Mail, down to 91 MB from 287 MB. 

Speculation has been running wild that this was an indication that this dramatic weightloss is an indication that Apple is looking toward minikernel type operating systems and the types of platforms that this would indicate – mainly leading to more ‘real OS X on the iPhone’ discussions.  Others have speculated that the weight reduction is due more to the loss of the PPC code in 10.6, or the switch from language (.lproj) files in each app to a system-wide localization database.

While there’s no denying that the loss of size is dramatic, it’s actually less of a reduction than I can get by running running XSlimmer – to use Mail as an example, the xslimmed Mail weighs in at a svelte 24.7 MB – significantly lighter even than the version shipping with Snow Leopard.  This, I’d think, very much argues that the size reductions can be entirely explained by loss of the PPC code and the language files.  In fact, the extra 70 MB might even be new features – hey, we can hope, right?

  3. This works wonders on both PPC & Intel based macs. The license is sensible, it allows you to use one copy on all YOUR macs (not your buddy’s). I came to two realizations, first off the fact that this app is security paranoid is a pain in the a**. You end up typing in the admin password over and over and over… But, it’s a one time deal, they’re aware of the unpleasantness, and they are mulling fixes that preserve security while not being inconvenient. The other realization is that most Intel based Macs have pretty big disks so regaining a couple of gig isn’t that big of a deal. On the other hand my PowerBook got a new lease on life, 2 gig on a 40 gig drive IS a big deal. Yay!

    Based on the PowerBook alone, to me, Xslimmer is definitely in the top tier of Indie software.
