I am using a MacBook Air M3 with macOS 26.0.1 (Tahoe). The official Minecraft Launcher will not open.
The icon bounces in the dock and then stops, no window appears.
I have fully reinstalled the launcher, tried Rosetta, Terminal launch, cleared caches and com.mojang folders — no effect.
It appears that the embedded WebView for Microsoft login is broken on macOS 26.
Thank you for your report!
