Celestia Forums

Slightly off-topic. But we (the Mac version) are to be found on the OS X-software download section of apple.com

The page has been added on October 10.

Seems they consider it to be okay software as well.
If only the bugs introduced with 10.3.5 got fixed (freezes computer if ring shadows are enabled, see OS X bug thread)

It looks like MacOS 1.4 (Tiger) may be available in the not too distant future. If someone is beta testing it and reporting Celestia's graphics problems to Apple, that might help to get the bugs out of Tiger's graphics drivers.
