Has anyone noticed that as of 10.10.4, it is no longer possible to run the defaults write command to enable Secondary Mouse Click??
I have a login script that runs the command:
sudo -u $3 defaults write com.apple.driver.AppleHIDMouse Button2 -integer 2
This has worked on all OS X versions so far however not currently working on 10.10.4.
Its an interesting error as the Sys Prefs GUI displays that button 2 is set for Secondary Click but it is not working. If you go into Sys Prefs and manually change the option then put it back to Secondary Click, all is well however this is not an option when managing many hundreds of Mac's.
I would be very interested to hear if anyone else has discovered this and of course if someone has a fix?
