Is it possible to run PUBG MOBILE on Mac OS?

Instead of trying to run a game not made for your platform on your Mac, the best approach would be to run the game in a Virtual Machine. Interestingly the Android emulators we use are also Virtual Machine, but in your case the emulator in itself is not made for your Mac. So you should try to search for an emulator that is not a modified form of Windows compatible version but originally designed for running on Mac system.

Incase if you can't find a suitable android emulator then you can download a virtual machine software (like VMware or VirtualBox) for Mac. Then run the android OS iso file in it. By android OS, I am referring to Android x86 based Phoenix OS, Prime OS etc. These are specifically designed for playing games and enable us to do keyboard mapping.

The best method: There is a feature in Mac itself which enables us to run any other operating system. It is called Boot camp assistant. It is very similar to dual booting. You can either install Windows in your machine or directly install PhoenixOS / Prime OS. Both of them are available as exe installer (if you decided to install windows in your Mac) as well as iso image (if you chose to just install android os)
