Mac System Extension Approval Error: Here's the Fix

You're trying to install an app on your Mac and get "System Extension Blocked" or "Cannot verify developer."

This is Apple's security being cautious - not malware. Simple fix.

Why Apple Blocks Extensions

macOS System Integrity Protection (SIP) blocks unnotarized extensions.

Fix #1: Approve in System Preferences

1. System Preferences > Security & Privacy
2. Find blocked extension message
3. Click Allow (enter password)
4. Restart Mac

DONE!

Fix #2: Disable SIP (trusted apps only)

1. Restart in Recovery Mode (Cmd + R)
2. Open Terminal
3. Type: csrutil disable
4. Restart and install
5. Type: csrutil enable
6. Restart
