Tahoe Electron Detector Checks Your Apps
7 October 2025
Thanks to a post by Peter Lewis, the man behind Keyboard Maestro, on that forum, we heard about Tahoe Electron Detector, a utility that checks all of your installed software applications for an Electron bug that calls a private and undocumented API "that's causing system-wide slowdowns in macOS Tahoe."
Once you've run the troublesome Electron app, the system slows down until you reboot it. Unfortunately, you may assume some other software is the cause of the slowdown (like Keyboard Maestro), which is driving developers nuts.
Craig Hockenberry's Tahoe Electron Detector can find the culprit quickly for you, though. He explains:
Luckily there's script written by Tomas Kafka that lets you do the check all your apps quickly and easily. I took that script, updated some parts that required Xcode to be installed and wrapped it up in an Apple Script applet that's easy to download and run.
We ran it on our system (which is loaded with image editing applications and beta software) running macOS 15.7.1 Sequoia to see what kind of trouble Tahoe would cause for us if we upgraded.
As the screen shot above shows, it discovered a few problems. Most notably for photographers was Excire v12.0.0, which is not the current version. A few useful utilities that are up-to-date, however, are concerns.
The utility doesn't seem to check scanner or printer drivers but those aren't likely to use APIs Apple hasn't documented.
