[macOS 26.5] Menu bar icon fails to render — NSStatusItemView scene invalidation error

Bug Report: Menu Bar Icon Fails to Display on macOS 26.5 ZeroTier Version: 1.16.1 macOS Version: 26.5 (Build 25F71)

Summary After upgrading to macOS 26.5, the ZeroTier menu bar icon no longer appears. The app seems unresponsive or "broken" from the user's perspective, but the underlying network daemon continues to function correctly.

What Happened The ZeroTier UI (ZeroTier.app) fails to render its NSStatusItem (menu bar icon) after the macOS 26.5 update. The following errors are repeatedly logged in the system console: [NSStatusItemView] No matching scene to invalidate for this identity. [BSBlockSentinel:FBSWorkspaceScenesClient] failed! This appears to be caused by a breaking change in macOS 26's Control Center Scene management system, which affects how menu bar status items are registered and invalidated.

What Still Works Despite the UI failure, the core ZeroTier service remains fully operational:

zerotier-one daemon is running Node status reports ONLINE Joined networks show status OK The virtual network interface (feth*) is UP and RUNNING IP assignment and routing work as expected This can be verified via CLI:

$ zerotier-cli status 200 info 1.16.1 ONLINE

$ zerotier-cli listnetworks 200 listnetworks OK PRIVATE feth4549 10.x.x.x/24

Steps to Reproduce Upgrade macOS to version 26.5 (Build 25F71) Launch /Applications/ZeroTier.app Observe that no menu bar icon appears Check system logs for FrontBoardServices / BaseBoard errors related to NSStatusItemView Expected Behavior The ZeroTier icon should appear in the macOS menu bar after launch, providing access to network management UI.

Actual Behavior No icon appears. The process (ZeroTier, PID visible via pgrep) is running but the UI is not accessible. The system log shows scene invalidation failures tied to macOS 26's updated Control Center architecture.

Workaround The network remains functional. Use the CLI as a temporary workaround: zerotier-cli status zerotier-cli listnetworks zerotier-cli join
