CrashPlan Proe 3.8.2010.2 on Mountain Lion 10.8.5

Posted: February 22nd, 2014 | Author: | Filed under: CrashPlan, Mac OS X | 1 Comment »

I recently had an issue where I could not load the CrashPlan proe server onto a 10.8.5 Mac Mini. The app installed however when I asked for the management interface on port 4280 I was greeted with a URL redirect and a blank white page. I was also getting this from /Library/Logs/PROserver/proserver.startup.err

[02.22.14 11:45:02.159 INFO main temPropertiesLoader.loadSystemProperties] * loading properties from: conf/

The solution was the following:

stop the service launchctl unload /Library/LaunchDaemons/com.crashplan.proserver.plist
edit launchd plist to point to /System/Library/Java/JavaVirtualMachines/1.6.0.jdk/Contents/Commands/java instead of /usr/bin/java
then rm /Library/CrashPlan/.proserver_identity
start the service and profit!
