Macbook Pro 2015 - Client Crashes After Game - Causes computer to crash in 5 seconds

Note: This happens every other game to me (literally 1 in 2).

I've tried reinstalling and reupdating client.

I think issue may be in adapter conversion ( I use an apple to USB-C to USB with Magicelec Mechanical Keyboard) as the problem started after I changed from PC to Mac.

Either way, game becomes unplayable because it crashes and potentially corrupts files on my computer after every game.

Pls Riot Engineers work harder or be more competent. Literally every other game works perfectly and they have way smaller dev teams.
