AE cc2020 Comp Preview Not working on macOS
I currently have AE cc19 & AE cc20 installed on my MAC. AE cc19 works fine and that is what I have been using. I downloaded AE cc20 and tried to open a project. Upon opening ever asset is available within the project. When I open a composition I can see the video output on my HDMI & SDI monitors, however I cannot see the video in the Comp monitor on my desktop screen. It simply shows up as blank. Also when I close AE cc20 it does not shutdown properly, I manually have to quit since it will say 'Application not responding'. I have reset the preferences to no avail.
system specs
MacPro (Mid 2010)
macOS High Sierra
2 x 2.66 GHz 6-Core Intel Xeon
64GB 1333 MHz DDR3
ATI Radeon HD 5770 1024mb
Any help would be appreciated.
thanks
Joe
