I use Rescue for unattended access for Mac's that are on our network. Sometimes the install for unattended access just borks and you cannot remove it by revoking access. All the Macs are running 10.10.5 and the terminal removal for the tmp directory did not work.
I was able to search the system files and remove all files relating to LogMeIn.
I then had to remove 'com.logmein.Rescue.plist' from HDD->users->[username]->library->preferences.
There was one more folder 'com.logmein.Rescue.savedState' in
HDD->users->[username]->library->saved application state.
Once I deleted these other entries, after a restart the Resuce app was permanently removed.
This is still sometimes an issue for me.
LMI Rescue Unattended Access (UA) will cease to work. The Rescue icon is grey out in the menu bar and the applet must be removed manually.
I have found that it is easily removed by deleting the LMI folder/file references in:
Take note of the UA number of the folder name located in " \Library\Application Support\LogMeIn Rescue\Unattended\".
Open terminal and run the following to clean up any remaining traces of UA :
sudo rm -rf com.logmeinrescue.unattended.agent."UA number"
For this example: sudo rm -rf com.logmeinrescue.unattended.agent.1666661
Reboot the Mac
