[2020] Client crashes while loading up and crashes in game too often

Hey everyone,

On my MacBook Pro 13 inch 2014 model, I would have the issue of the client crashing while loading up several times before being able to play.

I got the MacBook Pro 16 inch recently and now in addition to the previous issue, randomly while playing rs3, everything will freeze. I can not figure out what triggers it as I can just be standing there AFK and it will happen. During these 1-3 seconds freezes, if I click too much on the screen(like if im trying to spam click food), the client will completely crash. If I just don't click anything, then it won't crash.

This makes it very hard to PVM and really ruins the playing experience. I have tried searching for fixes and have done everything like updating my MacBook, reinstalling, deleting caches etc.

Any advice?
