Electron Apps Causing System-Wide Lag on MacOS 26 Tahoe

Michael Tsai, back on September 30, compiled a roundup of links regarding Electron apps causing systemwide lag on MacOS 26 Tahoe. The reason, seemingly, is that the Electron framework was overriding a private AppKit API. Of course.

Tomas Kafka wrote a shell script to find un-updated Electron apps on your system. Craig Hockenberry took Kafka’s shell script and turned it into an easy-to-use AppleScript application.

So, yes, Theo Browne, “software dev nerd”, Electron really is “that bad”. It’s actually, if anything, worse.
