According to the README at
ReviewBoard at one point was available for OS X:
It can be downloaded from:
The downloaded file will be named something similar to:
bitnami-reviewboard-2.5.3-1-linux-installer.run on Linux or
bitnami-reviewboard-2.5.3-1-linux-x64-installer.run on Linux or
bitnami-reviewboard-2.5.3-1-osx-x86-installer.dmg on OS X x86
I can't find an OS X installer on the site anywhere. Is there an older version I can download, or a reason it is no longer distributed?
