Unable to start Adobe InDesign, because you do not have sufficient permissions to access the Preferences folder. Make sure you have sufficient privileges, then restart Adobe InDesign.
Sometimes the installer fails to properly set the permissions. Which OS, and which version of ID?
Both are the newest OS of Mac 10.11 Beta version & Indesign CC (2015)
I had install & uninstall over 3 times, please help
See Cant launch new inDesign CC | Adobe Community
Where it says Version 9, substitute Version 11
You do understand that running a Beta OS is likely to have behavior issues, right?
