I've seen this stock suggestion posted on many discussions. I've solved the problem with LiveChat with Adobe Support:
Mohammed: As I understand you are not able to launch CC apps since it is giving error "Unable to launch Adobe InDesign as you lack sufficient permissions to access the preferences folders". Is that correct?
Paul: Yes
Mohammed: Please open a Finder window. Choose Go > Go To Folder. Type ~/library and you will get Preferences folder.
Paul: In Library now
Mohammed: Are you able to find preferences folder?
Paul: yes
Mohammed: Control-click the folder and choose Get Info.
Mohammed: Expand the Sharing & Permissions section.
Mohammed: Click the lock icon in the lower-right corner. Enter your administrator user name and password when prompted, and then click OK.
Paul: done
Mohammed: Please click on + icon and add the Admin and all users showing.
Paul: done
Mohammed: Set permission for all users and admin as read/write
Mohammed: Click the Gear icon, and select Apply to Enclosed Item
Paul: to each of the individual users and groups?
Paul: one at a time?
Paul: I've done it.
Mohammed: Please open a Finder window. Choose Go > Go To Folder. Type ~/library/Application support and give full permission to Adobe folder.
Paul: That's completed... I've added all the users and groups, given each 'Read and Write" and extended the permissions to all enclosed items.
Mohammed: Now please open a Finder window. Choose Go > Go To Folder. Type /library/Application support and give full permission to Adobe folder.
Paul: OK, I understand... I am proceeding with your instruction.
Mohammed: Thank you.
Paul: I'm finished.
Mohammed: Please close all Adobe Applications and then launch InDesign CC and let me know the result.
Paul: OK... looking good so far Mohammed... fingers crossed!
Paul: Thanks Mohammed... it's launched!
Mohammed: Excellent, I am so happy to hear this from you.
Mohammed: I certainly appreciate your patience in this process.
Paul: And I yours.
