2020 iMac 27"

[Bikeracer]

Because my old 2012 iMac stopped turning on I have had to get a new iMac
I noticed that Scal 5 was being very slow and laggy on the new Mac using Catalina os.

For anyone with similar problems the answer is to go into Finder and open the ' get info' on the Scal app and tick the box to run in low resolution.
