[Patch Notes for August 22nd, 2019]

i had yosemite and was able to play just fine.

 

yesterday i downloaded catalina and updated my mac.

 

now i can't play. i click on the play icon, and it does nothing. is there something i need to do?  I'm really a very very lay person when it comes to computers and technology. so a step by step would be best! 

 

thank you
