Troubleshooting Steps to Resolve the Error

Here’s a systematic approach to tackle the “errordomain=nscocoaerrordomain&errormessage=指定されたショートカットが見つかりませんでした。&errrorcode=4” error:

Verify and Reset Keyboard Shortcuts:
- Application-Specific Shortcuts: Meticulously examine the application’s settings to ensure the desired shortcut is correctly assigned to the intended function. If unsure, consult the application’s documentation or online resources for the default shortcut configuration. Many applications allow you to reset shortcuts to their factory defaults, which can resolve conflicts.
- System-Wide Shortcuts: Navigate to System Preferences > Keyboard > Shortcuts. Explore the various sections (e.g., App Shortcuts, Services) to identify any shortcuts that might be interfering with the application’s functionality. Consider disabling or modifying these shortcuts if necessary.
Relaunch the Application:

A simple application relaunch can often clear temporary glitches and memory issues that might be causing the error. Quit the application entirely and relaunch it to see if the problem persists.
Update the Application:

Outdated applications can harbor bugs and compatibility issues. Check for available updates within the application itself (usually under an “About” or “Help” menu) or visit the developer’s website to download the latest version. Installing updates can rectify known issues and potentially resolve the shortcut error.
Repair Disk Permissions:

Disk permission issues can sometimes prevent applications from accessing necessary files. Utilize the Disk Utility application (located in /Applications/Utilities/) to repair disk permissions. Launch Disk Utility, select your primary drive, click on First Aid, and then choose Repair Disk Permissions.
Remove Conflicting Applications:

If you suspect a third-party application might be interfering with the specific application’s shortcuts, temporarily uninstall the suspected application to see if the error disappears. If removing the application resolves the issue, consider reinstalling the application and adjusting its settings to avoid shortcut conflicts.
Reinstall the Application:

As a last resort, if none of the preceding steps alleviate the error, reinstalling the application can replace potentially corrupted files and restore the application’s default settings. Remember to back up any essential data within the application before reinstalling.
