## Summary
On MacOS the system tray icon is off-color because it uses the gray-colored `kdeconnectindicatordark` icon which does not match the rest of MacOS.
BUG: 430226
I've used two patches to fix this:
1. Always use the status `KStatusNotifierItem::Passive` on MacOS. `KStatusNotifierItem` will only mark the icon as a mask (which is needed to allow it to dynamically switch between light and dark theme) [if the status is passive](cff7c337ab/src/kstatusnotifieritem.cpp (L1079-1081)).
2. The above should theoretically be enough to fix the issue and I swear at one point it was all that was needed. However, to fix this issue in my dev environment I also needed to pass in a `QIcon` with `setIsMask(true)` instead of setting the icon by its name. And I also use the `kdeconnectindicator` instead of `kdeconnectindicatordark` icon.
## Test Plan
The icon now renders in the correct color, regardless of whether devices are connected:
 
## Future work
Once I've verified this PR is working in the right direction, I want to look into making the icon gray (and hopefully a much easier-to-see gray) when no devices are connected!
For example, WireGuard, when not connected, looks like this:
 
P.S. I've been testing off the v21.12.2 tag since the master branch doesn't compile for me, so I haven't tested this change on the latest dev commit. But there should be no conflicts.
