Install OCTGN (fingers crossed) WINEPREFIX=~/.wine-octgn wine PATH-TO-OCTGN-INSTALL.exe (NOTE: Replace PATH-TO-OCTGN-INSTALL.exe with the full path to your downloaded OCTGN installer). Choose yes on following prompts. Make sure "Run OCTGN" is selected. If you see flickering artifacts, just close the application – it should be fine when you run it next time.
Launch OCTGN with WINEPREFIX=~/.wine-octgn wine ~/Documents/OCTGN/OCTGN/OCTGN.exe. This is how you launch OCTGN from now on, but I've created a small applescript that you can download here that makes it easier to launch: http://goo.gl/oo2iRI. Download and unzip, and double-click. If you followed the instructions it should launch OCTGN.

Also, I want to share one thing, if you're looking to replace your Mac to other variant then I would love to highly reccomend to taking MacBook Pro m1 cause apple says" the new chip deliver 18% better CPU and 25% better GPU performance over the previous design”. it's true MacBook Pro price in bd is much higher compare to other county. I want to listen to it from an expert. Otherwise, this is an amazing device to play anything or heavy work, also Which have ability to gives you faster using experience.
