macOS Tahoe and BigFix Self Service

1

There is a known problem with macOS Tahoe and Electron apps which appears to affect BigFix Self Service. Here’s an AI summary of the issue:

Electron apps cause high GPU usage and lag on macOS Tahoe (version 26) because they use a private Apple API for window rendering, which conflicts with the new OS. The fix involves updating the Electron framework within the apps to a version that no longer uses the private API. Users must wait for app developers to update their applications with the fixed Electron version.

What’s Happening:

  • macOS Tahoe’s New Rendering: The new version of macOS, Tahoe, has a different way of handling windows and their shadows.
  • Electron Apps’ Hacky Method: Electron apps use a private, unofficial Apple API to customize window corner shadows for cosmetic reasons.
  • The Conflict: When macOS Tahoe encounters this private API usage, it can’t render the windows efficiently, leading to high GPU usage by the WindowServer process.
  • User Experience: This conflict results in system slowdowns, sluggish scrolling, delayed clicks, and increased fan activity on affected Macs.

Will the Self Service app be updated soon to address this? All of our BigFix managed macs run the Self Service app, so we want to avoid problems as Macs are upgraded.

Hi all,
during the certification process of Self Service App on Tahoe we found several issues. So the Electron bug reported here is only one of the problems, we are working to fix the others.
At the moment, there is no ETA yet for the support, but I’ll keep you posted.

The BigFix Team.
