MacBookAir M1, Big Sur - not launching StarCraft 2

StarCraft 2 not launching on MBA M1 - Big Sur.

~/Library/Application Support/Blizzard/StarCraft II/variables.txt file has been adjusted as recommended by StarCraft support posts:

  1. change vsync setting to “vsync=true”
  2. change GraphicsApi setting to “GraphicsApi=Metal”

Neither solution has resolved the problem: After clicking “PLAY” button under StarCraft 2 on the BattleNet V5.0.6.83830, the button changes to “LAUNCHING”. After a few seconds, the button returns to “PLAY”…StarCraft 2 does not start, neither does the StarCraft2 icon show on the taskbar.

Note: WoW and Diablo load fine on this computer.

I would appreciated any tried/tested solutions to this issue.

Thank you,
Michael

Any suggestions out there from fellow Mac M1 owners?

Same happened to me. Try changing your Mac system name, that fixed mine and seems to work now. I just took the space out of mine, something like “MyMac” should work. SC2 quit unexpectedly - #2 by Zuvykree

I saw someone else on Reddit got it working on another M1 Mac by changing the name:

I’ve seen people mention system performance anywhere from 45-60 fps at 1080p low settings (Mac mini YouTube video) to over 60 FPS on a MBP on medium with a few settings set to ultra. Seems to make a drastic difference having a discrete graphics card. I’d like to know if an eGPU would help.

Wow…yes!
Surprising…after all the removals, reinstalls, and file tinkering, simply removing the space from my computer name fixed it.

Hey, what I can I do if I haven’t Blizzard folder in /Application Support directory?
pls help

eGPUs are not supported on Apple Silicon Macs (such as Macs with the M1). What would REALLY help is an Apple Silicon native version of StarCraft II. :wink:
