I came across this after the security update flop.
- 1. Make a backup first!
- 2. Disable SIP
- 3. Boot to the recovery partition > Open Terminal > Type in csrutil disable
- 4. Reboot
- 5. Download Safari 13.1.2
- 6. Safari 13.1.2 = http://swcdn.apple.com/content/down...pewxts5rfjlkhtdvcy/Safari13.1.2MojaveAuto.pkg
- 7. Download AppCleaner v3.5 – https://freemacsoft.net/appcleaner/
- 8. Download Pacifist v3.6.2 – charlessoft.com/cgi-bin/pacifist_download.cgi?type=dmg
- 9. Install both apps
- 10. Use AppCleaner to remove Safari 14.0 – Go to preferences and uncheck “Protect default OS X apps”. Drag safari.app over to the app then select all files. then click remove.
- 11. Install Safari 13.1.2MojaveAuto.pkg using Pacifist.app – Drag Safari13.1.2MojaveAuto.pkg over to the app. A new window will pop up. Highlight the main pkg in the list then hit install. You will see 2 admin prompts and a prompt to overwrite files, select overwrite all.
- 12. Reboot to recovery and re-enable SIP. Open Terminal > Type in csrutil enable
- 13. Reboot back to macOS. You are now back to Safari 13.1.2
