Error Creating "Directory/Applications/Time Doctor" (Mac)
If you are receiving this error when trying to install Time Doctor, attempt to manually create a folder inside your ~/Library/Application Support folder first.
If you are not allowed to do so, then there probably is an issue with your permissions.
The complete path for the cache should be ~/Library/Application Support/TimeDoctor.
To solve this, right-click on your Applications folder, select Get Info from the menu, and Allow read/write access for everyone.
