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!

    Trying to install this legacy version of Crashplan ProE on Mavericks. Saw the same error in the logs. Made this change and the server started up. Thanks for posting this!

    One note for anyone else who comes across this. You may need to use sudo to stop and start Crashplan on the command line. I used the following commands:

    Stop – sudo launchctl unload /Library/LaunchDaemons/com.crashplan.proserver.plist

    Start – sudo launchctl load /Library/LaunchDaemons/com.crashplan.proserver.plist
