I use to have the older version of pocketmac not sure which one but it worked fine no issues... i tried to update to pocketmac 4.1 and when i installed it the installation worked no problem. but when i click on the icon for the app nothing happens. i looked in the crash log and this is what i see...

Go to your library and delete the PocketMac plists. Then try to connect. I had an old version of PocketMac (perhaps a failed install) on mine and once I did this all is well now. I suspect these get recreated but in case your weary of doing this make a backup first.
