Versions

I tried on all three different builds (Atom stable, beta and nightly) downloaded on 7/15/20

Stable Version
Atom : 1.49.0
Electron: 5.0.13
Chrome : 73.0.3683.121
Node : 12.0.0

OS
MacOS 11.0, "Big Sur”, Apple Silicon, ARM64
Labels: Mac-BigSur
Labels: Mac-Arm64

Additional Information

Seems similar to issue with other Electron based applications.

Link to similar issue
https://bugs.chromium.org/p/chromium/issues/detail?id=1098899

The issue here is that Chromium hardcodes macOS page size to 4 KB, whereas on Apple silicon devices it's actually 16 KB. We managed to fix it in our fork of Electron by changing code that uses hardcoded page size: Unity-Technologies/electron@79a9fa9
