I am using Solidworks 2020-2021student edition on a iMac 5K with Parallel but getting error that my graphic card is not certified while it is running glitchy. Could you advise?

I just bought the 2020-2021 version of Solidworks student edition, but it is working very scraggy. i was able to allocate more storage so Solidworks could work  better but ca not get the graphic card certified error message resolved. Please advise.
