I didn't have this problem before. When i am trying to update Android Studio to 2.3, i get this:
Studio does not have write access to /private/var/folders/00/n4yy8fsx0njck05bfll1t3_w0000gn/T/AppTranslocation/2D9E214E-60BE-41D9-9843-3536E011FD7E/d/Android Studio.app/Contents. Please run it by a privileged user to update.
The account that i am in is Admin account and i also tried to give full access to that directory.
chmod -R 777 /private/var/....
but nothing worked. Any help will be much appreciated.
