fix: notifications not displaying for menu bar app

[masonc15]

I noticed notifications weren't triggering on my Mac despite having them enabled in the menu. After investigating, I found the root cause: macOS silences notifications for foreground apps by default, and menu bar apps like MacThrottle (configured with LSUIElement, meaning no Dock icon) are treated as foreground.

The fix implements UNUserNotificationCenterDelegate and adds the willPresent delegate method to explicitly request banner presentation. This affects all users on all macOS versions since 10.14 Mojave.

Changes:

• Add UNUserNotificationCenterDelegate conformance to ThermalMonitor
• Set notification center delegate on init
• Implement willPresent to call completion handler with .banner and .sound

I've found this utility invaluable and have been using it constantly since reading your blog post a few weeks ago. I'm slightly new to OSS development, so let me know if I should change or improve anything. Thanks!

Interesting, this sounds legit but I wonder why notifications work for me?

[masonc15]

Yeah, I figured as much - definitely weird. I'm running MacThrottle on an M2 Macbook Air on Tahoe 26.2. Not sure if other people have experienced the same notification bug, but this patch got it working for me at least.

Also doesn't work here - macOS 26.3.1, v1.7.3 of the app.

OT: Thanks for making this app! Perfect for figuring out what actual thermal throttling does under relevant loads. [And what settings to choose for Factorio & whether to thermal mod :)]
