- Create a new folder /Applications -> Apple Apps
- Select all your Apple apps, and command-option-drag them into that folder to create aliases.
- Use a third party utility such as SNAX or iChange X to make the original apps invisible, or use the command line:
% /Developer/Tools/SetFile -a V /path/to/file
[Editor's note: After getting burned by this in a couple of the earlier updates, I've decided I just don't touch the Apple apps. I move other stuff to larger volumes, but I leave Apple's stuff where it sits. This looks like a unique solution which I may experiment with just from a "visually clean" perspective.]
