Finder Right-Click Menu Opens and Closes Immediately
I understand that since upgrading macOS, Finder's right-click menu appears briefly and then disappears before you can select an option. This may be caused by a temporary Finder issue, trackpad or mouse settings, incompatible third-party software, or an issue introduced by the macOS update.
1 - Choose Apple menu > Restart. When your Mac starts again, open Finder and test the right-click menu.
2 - Press Option + Command + Esc to open Force Quit Applications. Select Finder, then click Relaunch. Test the menu again.
3. Check Trackpad or Mouse Settings
Open System Settings > Trackpad and make sure Secondary click is enabled under Point & Click. Try the two-finger click setting.
If you use an external mouse, open System Settings > Mouse and check that Secondary Click is enabled. Disconnect and reconnect the mouse, or test with the built-in trackpad to see whether the issue is specific to the mouse.
4. Try Control-Click
In Finder, hold down Control and click a file or folder. This should open the same contextual menu.
If Control click works but the two-finger click does not, the issue may be related to the trackpad or mouse input. If both menus disappear, Finder, macOS, or background software may be involved.
5. Test in Safe Mode
Safe Mode can help identify whether third-party software is interfering with Finder.
On your M1 Pro Mac, shut down. Press and hold the power button until startup options appear. Select your startup disk, hold Shift, then click Continue in Safe Mode. Open Finder and test the menu.
If it works in Safe Mode, restart normally and investigate recently installed apps, mouse utilities, clipboard managers, login items, and Finder extensions. Disable nonessential items one at a time and retest.

6. Review Login Items and Extensions
Open System Settings > General > Login Items & Extensions. Review apps that open at login and third-party extensions, especially those associated with Finder. Temporarily turn off nonessential items or extensions, restart, and test again.

7. Check for macOS Updates
Open System Settings > General > Software Update. If an update is available, back up your Mac before installing it. Restart and test Finder again.
8. Test With a New User Account
If the issue continues, create a temporary standard account Sign out of your usual account, sign in to the new one, and test Finder.
If the menu works in the new account, the cause may be a setting, login item, or other issue specific to your usual account. If it also fails there, the issue may affect the whole system. You can return to your usual account after testing.
9. Run Apple Diagnostics
This can check for certain hardware issues, although the symptoms are more suggestive of a software problem.
Shut down your Mac and disconnect unnecessary external devices. Press and hold the power button until startup options appear. When you see your startup disk and the Options gear, release the button. Then press and hold Command (⌘) + D until Apple Diagnostics starts. Follow the onscreen instructions.
If a reference code appears, write it down for Apple Support. A clean result does not rule out a software issue.
