If your Mac refuses to shut down, hangs on a black screen, or stays stuck with apps not closing, this page is for you.
The most common reasons a Mac won’t shut down
These are the issues that Keith Thomas identifies most often during on‑site visits:
• Apps refusing to quit
• Background processes still running
• iCloud syncing delays
• macOS update processes stuck
• Damaged system files
• Login items preventing shutdown
• External devices interfering with shutdown
• FileVault encryption delays
Quick checks you can do yourself
These steps solve around 60% of shutdown issues.
Check 1 – Quit all apps
Press Option–Command–Esc and force‑quit any app that is not responding.
Check 2 – Disconnect external devices
Unplug USB drives, hubs, printers, monitors and external SSDs.
Check 3 – Restart instead of shutting down
Go to Apple menu → Restart. This often clears stuck processes.
Check 4 – Check for macOS updates
Go to System Settings → General → Software Update.
