Here's the solution:
1. Open terminal
2. Copy the following command and paste it into terminal (then hit return):
sudo spctl --master-disable
3. You must now enter your password (you WILL NOT see it being entered as you type it.) Then hit return again and quit the terminal.
4. Open System Preferences and choose "Security & Privacy".
5. Look at the "general" panel. You should now see "the third choice" ("anywhere") available again.
I'm not the OP but I am experiencing the same issue, and these steps do not resolve it for me. I've downloaded, again and again, Standard Notes from their official site. I unzip it and move it to /Applications. I've run sudo spctl --master-disable in cli and checked Anywhere in the Security panel.
"The application 'Standard Notes' cannot be opened."
Console produces the following:
Code:
Oct 11 15:52:32 MSMAC com.apple.xpc.launchd[1] (com.apple.xpc.launchd.oneshot.0x1000001d.Standard Notes[8718]): Could not find and/or execute program specified by service: 13: Permission denied: /Applications/Standard Notes.app/Contents/MacOS/Standard Notes
As per a suggestion I found elsewhere, I try chmodding the app 755.
Try app again. This time the icon appears in the dock but the system claims that the app is damaged and I should move it to the Bin.
Meanwhile, the console now gave more information:
Code:
Oct 11 16:01:46 MSMAC com.apple.xpc.launchd[1] (com.apple.xpc.launchd.oneshot.0x1000001e.Standard Notes[8759]): removing service since it exited with consistent failure - OS_REASON_EXEC | Gatekeeper policy blocked execution
People who have upgraded from a previous macOS version (Mojave->Catalina) have been able to run the application. Mine is a fresh install.
Clearly the sudo spctl --master-disable panacea does not actually stop Gatekeeper's draconian policies to be applied. I'd like to find out which policy that is exactly.
