I cannot open lightroom classic cc on my macbook pro - it is not responding. I have uninstalled and reinstalled the app but no success. Also getting message unable to sync. I can't find an email or number to contact adobe support which is very frustrating too. Can someone please help me, I am stuck and have a big presentation to make tomorrow. Thank you Serena
Sorry that Lightroom Classic CC is freezing on your MacBook Pro.
Could you please uncheck the option "use graphics processor" under the Preferences> Performance menu in Lightroom?
