After some searching we found out that Passenger doesn’t run on Mac OS X because it segfaults on 64-bit BSD systems. All Core 2 Duo and Xeon systems are 64-bit, so that includes newer Mac Mini, Macbook, Macbook Pro, Macbook Air and Mac Pro.
A workaround for now is running Apache in 32-bit. Because Apache is compiled as a Universal binary, that is really easy to do.
The quick but short term solution is to start httpd by hand:
The lasting solution is to change the Apache plist:
First we create a backup of the current plist.
After that we open the plist in our favorite text editor.
And restart Apache:
Launchd will automatically start Apache for you after the stop command. Now Apache is running in 32-bit and should run Passenger just fine.
Update: Fixed in 1.0.2. Please update your gem and
passenger-install-apache2-module if you’re having this problem.
