When you get the error "nothing found to load" after running
launchctl load. For example:
$ launchctl load ~/Library/LaunchAgents/org.virtualbox.vboxwebsrv.plist nothing found to load
First check to make sure the package isn't listed as disabled in the global overrides file:
If the package isn't listed in the overrides file, launchd documentation offers another file it may be located in.
First get your user id by running
id on the command line:
$ id -u 201
Now use this id to find the file:
/var/db/launchd.db/com.apple.launchd.peruser.201/overrides.plist. The override entry should be listed in this file.
In the example given above for virtualbox, you would remove these lines from that overrides.plist file:
<key>org.virtualbox.vboxwebsvc</key> <dict> <key>Disabled</key> <true/> </dict>
