first of all thank you for taking the time to replay,
I fail to mention that i'm using windows 10 and this is my very first time to setup MacOs on my Pc (sorry for that) ,
But i came to conclusion that i have problem with my AMD processor (and might have another problem with my gpu 'sapphire rx580' ) ,
So is there any guide for AMD windows user or any other MacOs version that is ready & compatible with my pc ? doesn't have to be Catalina i'm OK with any ver.
