How to unlock the FPS limit on MacOS?

I know it’s easy to unlock the fps on Windows and iOS/Android, using the options.txt file. However I can’t find it anywhere on Mac. There are previous instructions about it being in /Library/Blizzard/Hearthstone/options.txt – but there are no Hearthstone folders in the Library folder anywhere that I can find. It seems like it’s changed since these instructions were posted (years ago).

Does anybody know how to do it on MacOS in 2019?

There’s really no reason why my iMac should limit the FPS to 30…

hey mate ! did u solve the problem? tell me
