Electron Apps Causing System-Wide Lag on Tahoe

This script detects apps with not yet updated versions of Electron.

Gist: https://gist.github.com/tkafka/e3eb63a5ec448e9be6701bfd1f1b1e58

See:

• electron/electron#48311 (comment)
• Michael Tsai: Electron Apps Causing System-Wide Lag on Tahoe
• Avarayr's tracker of affected and fixed Electron apps

Fixed versions:

• 36.9.2
• 37.6.0
• 38.2.0
• 39.0.0
• and all above 39

Temporary workaround:

Run

launchctl setenv CHROME_HEADLESS 1

on every system start. The CHROME_HEADLESS flag has a side effect of disabling Electron app window shadows, which makes them ugly, but also stops triggering the issue.

What I also make

🌦️ Weathergraph is my weather app that shows hourly forecasts as charts instead of lists. See a week's worth of temperature, precipitation, wind, UV, and pressure in a single visual.

Built in Swift/SwiftUI for iPhone, Apple Watch, and Mac. Highly customizable if you're into that.

"I first downloaded the app because I caught sight of the large complication on an Apple Store employee's Apple Watch and asked about it. This is the perfect weather app. All information beautifully presented and easily accessible." - lucenvoyage
