Preference Error: Could not load sharing preference pane
For some reason my second computer (iMac 27) is no longer showing up on the left pane of any finder window on my MBP. The iMac is running Yosemite and the MBP is running Mavericks. So I open System preferences to see if there is a problem with "Sharing" on the MBP. I'm getting a Preference Error: Could not load sharing preference pane. Do I need to install the update to fix this? I'm not ready to commit to Yosemite completely. I build apps for iOS and Mac and really need to test in both OS environments.
MacBook Pro, OS X Mavericks (10.9.5), 17 2.4ghz i7
