Fix Guide: Sequoia Universal Control 'Mouse Cursor Disappearing'
Symptom: When moving your mouse from your Mac to an iPad or another Mac using Universal Control in macOS Sequoia (15.x), the cursor becomes invisible or gets stuck at the edge.
Why this happens
Universal Control relies on a low-latency handshake over Bluetooth and Wi-Fi. In Sequoia, the "Screen Continuity" daemon can crash if the display arrangement in System Settings doesn't match the physical location of the devices.
Recommended Troubleshooting Tool
Before proceeding with manual fixes, we recommend using OnyX. The preferred tool for deep system maintenance and resetting the macOS Bluetooth stack.

Fix 1: Reset Display Arrangement (Free)
Force macOS to recalculate the "edge" of the screen.
- Go to System Settings
- Navigate to Displays.
- Re-arrange
- Click Arrange... and move the second device slightly, then move it back. Click Done.
Fix 2: Toggle Handoff and Bluetooth (Free)
Universal Control is part of the Handoff suite.
- Toggle Bluetooth
- Turn Bluetooth OFF and ON on both devices.
- Toggle Handoff
- Go to System Settings > General > AirDrop & Handoff.
- Turn "Allow Handoff between this Mac and your iCloud devices" OFF and then ON.
Fix 3: Kill the Continuity Daemon
When the feature works but the cursor is invisible.
- Open Terminal
- Run:
killall universalcontrold
- Wait
- The process will restart. Move your mouse to the edge of the screen to re-link the devices.
Recommended Tool: CleanMyMac X
Universal Control and Handoff rely on clean network and Bluetooth preference files. CleanMyMac X can help by Repairing Disk Permissions and clearing out system logs that may be flagging false errors in the Continuity daemon.
