Seriously!!?? This means I have to update my system to fix this bug!!?? I’m on OS X Sierra (10.12.6) and InDesign, Id 15.0 will only work with OS X High Sierra 10.13!!! Come on Adobe! Are you in on it with Apple for planned obsolescence to force us to update! At the price we pay every month here in Canada!?
