I've updated my Healpix viewer app for Mac OS X. It's now built as a universal binary, so performance on Intel Macs should be significantly improved.
I've added the facility to edit the map color range values directly (to see detail even if there are outliers) and export of TIFF images of the viewport.
The new version is posted on my personal website:
