macOS Sequoia 15.4.1 may not be a huge update. However, it has arrived with a range of bug fixes and performance enhancements. Though there are still quite a few lingering issues that need to be addressed sooner rather than later. In this detailed article, let’s discuss the 10 major issues in macOS Sequoia 15.4.1 and their effective solutions. So, if your Mac is behaving weirdly after the recent software update, read on to spot the issues and resolve them.
1. Battery Drain After Update
Recently, a good many users have reported significant battery drain after upgrading to macOS Sequoia 15.4.1
- On your Mac, head over to System Settings > Battery > Usage History to identify any power-hungry apps.
- That aside, I’d also recommend you disable Background App Refresh and automatic updates.
- Also, reset the SMC (System Management Controller) on Intel Macs or restart your Mac on Apple Silicon to refresh power management systems.
2. Wi-Fi Connectivity Issues
After the update, a handful of macOS users have complained about frequent Wi-Fi dropouts or slower speeds.
- Navigate to the System Settings > Network > Wi-Fi, forget the current network, then reconnect.
- Also, try renewing the DHCP lease under Wi-Fi details.
- Reset network settings using Terminal with
sudo ifconfig en0 downand thensudo ifconfig en0 up.
3. Bluetooth Not Working or Laggy
Bluetooth devices either won’t pair or experience lag, especially with peripherals like Magic Mouse or AirPods.
- Open Finder > Go > Go to Folder and enter
/Library/Preferencesthen deletecom.apple.Bluetooth.plist. - Restart your Mac and re-pair devices. If that fails, reset the Bluetooth module by holding Shift + Option and clicking the Bluetooth icon in the menu bar, then selecting “Reset the Bluetooth module”.
4. App Crashes or Not Launching
As per various complaints on Reddit and Apple Support Community, apps crash immediately after opening or refuse to launch entirely.
- Ensure apps are updated via the App Store or the developer’s website. If the issue persists.
- After that, delete the app’s preference files from
~/Library/Preferences, then reinstall the app. - You can also try booting into Safe Mode to isolate incompatible software.
5. Slow Performance and Freezing
macOS Sequoia 15.4.1 may slow down over time or freeze unexpectedly.
- To begin with, check Activity Monitor for resource-hogging processes.
- Now, clear system cache using a tool like OnyX, and disable login items via System Settings > General > Login Items.
- Consider resetting NVRAM and SMC for deeper performance issues.
6. External Monitor Not Detected
Some Macs no longer detect external displays after the update.
- Unplug and replug the monitor. Go to System Settings > Displays and click “Detect Displays”.
- If you’re using a USB-C hub, ensure it’s updated and supports video output. Also, reset NVRAM which stores display configuration.
7. Spotlight Search Not Working Properly
Spotlight fails to index new content or returns no results. Reindex Spotlight manually.
- Open Terminal and type
sudo mdutil -E /then press Enter. This will erase and rebuild the Spotlight index.
8. iCloud Syncing Issues
Going by several reports, Files, Photos, or Notes are unable to sync across Apple devices.
- Launch the System Settings app > Apple ID > iCloud.
- Toggle the affected service off and on.
- Sign out and back into iCloud if needed.
- Check Apple’s System Status page to rule out server-side problems.
9. Stage Manager Glitches
Stage Manager may misplace windows, overlap app views, or not activate.
- Open the System Settings app on your Mac > Desktop & Dock > Stage Manager, turn it off and on.
- Now, make sure to reset window arrangements by toggling “Recent Apps” off.
- If problems persist, log out and back in or reboot the system.
10. Continuity Features Not Working (Handoff, AirDrop, Universal Clipboard)
Continuity-based features break after the update for some users.
- Make sure Wi-Fi and Bluetooth are enabled and both devices are signed into the same iCloud account.
- Go to System Settings > General > AirDrop & Handoff and enable the necessary options. Restart both devices and try again.
