macOS: Icon style doesn't change when dark mode is being turned on/off

theit

WorkingHours version: 2.17.1
OS + version: macOS Tahoe 26.6.2
Device model: MacBook Pro M2

Just a minor "bug":
I configured macOS to automatically turn on/off dark mode. When I start Working Hours, the program's icon correctly reflects the OS's actual appearance. But it doesn't change anymore, neither when the OS style automatically changes nor when I manually switch the style in system settings.
The icon also doesn't reflect changes I make in the system settings' appearance tab under "symbol & widget style", i.e. standard, dark, transparent or colored.

But: Depending on the style selected there the icon is correctly being displayed in that style when I restart the program.

Thanks for reporting this. The problem was caused by WorkingHours replacing the Dock icon to draw the task-colored timer indicator. This feature was added in version 2.12.2. On macOS 26, replacing the icon bypasses the new adaptive rendering, so changes between Default, Dark, Clear, and Tinted are not applied correctly.

This macOS behavior affects other apps too and has been reported to Apple as FB20291186:

The next WorkingHours update will return to the native macOS Dock badge. A dot will appear only while the timer is running; paused and stopped timers will show no badge. This loses the task color, but allows macOS to render the app icon correctly in the selected system style.
