I have recently purchased a Macbook Air running Yosemite.
I wish to allow VoiceOver to be controlled by AppleScript. When checking the relevant check box in the VoiceOver utility and entering the correct iCloud password, the check box remains unchecked.
I have attempted to toggle the state of the checkbox with Voiceover disabled. i have also tried adding applications including script Editor, Autimator and VoiceOver to the allowed list of apps under privacy but to no avail.
Would anyone happen to know what setting is preventing this change from taking place under Yosemite? Perhaps there is a security setting I need to alter to permit this change?
Many thanks for any assistance.
