How To Fix errordomain=nscocoaerrordomain&errormessage=could not find the specified shortcut.&errorcode=4


If you are using an iOS iPhone or MacBook user, no offence, you might sometimes encounter an error message that reads something like errordomain=nscocoaerrordomain&errormessage=could not find the specified shortcut.&errorcode=4. Or you are an app developer, and while developing an application for macOS or other Apple applications, you are struck with this message and puzzling what to do. This article will be about how to resolve and prevent this error message and also what causes this error in the first place.

Know NSCocoaErrorDomain

NSCocoaErrorDomain is the error domain specific to the cocoa framework operating in Apple or iOS devices. Since the cocoa framework is widely used to develop macOS and IOS applications, NSCocoaErrorDomain is a systematised way of handling and communicating error messages within Apple’s cocoa framework.

could not find the specified shortcut

Errors are categorically classified into different domains so that the source of a mistake can be identified efficiently and measures can be taken to resolve the issue more deftly. Networking, data serialisation and file system tasks are some of the operations whose related errors are dealt with under the umbrella of NSCocoaErrorDomain.

Decode Message bit by bit.

Let’s start dismantling the message errordomain=nscocoaerrordomain&errormessage=could not find the specified shortcut.&errorcode=4 to make it more viable for use. Etc I’m

  • Error domain=nscocoaerrordomain: The first part of the message is the error domain. It reveals the domain from where the errors are incepting. In this case, nscocoaerrordomain refers to Cocoa framework-based applications on Apple iOS devices.
  • Error message– “could not find the specified shortcut”: The next part is an error message, which is self-explanatory. It reads “could not find the specified shortcut”, which means the specified command or shortcut is not found.
  • Error code-errorcode=4: The last part has an error code. In a programming language, an error code explains the nature or sometimes the source of a mistake. It is a numeric or alphanumeric representation of code, commonly known as bugs or faults. Errorcode=4 means an invalid argument was passed. Error codes help developers in navigating the issue within a specified domain.

Troubleshooting Steps

Every programming language or application development has a way to deal with the problems. Cocoa is no exception to commonly occurring programming problems a developer encounters frequently. The troubleshooting methodology may include:

1. Updating or reinstalling the app

App developers are working tirelessly to improve the software experience for end-users. So, do they constantly make amendments in enhancing and debugging the application for any potential fault? A new update for an application can be a resolution many times in resolving the dubious error. When updating the app to the latest version does not help, try uninstalling and reinstalling the app to eliminate any corrupted residual files.

2. Updating compatible OS version

Running a device on an expired OS may cause system applications to work slowly and improperly. Check the OS version; it should be equivalent to or surpass the minimum OS version supported by the application—update when the device prompts to avoid functional setbacks. Meanwhile, an alternative app compatible with the current OS can be used.

3. Do not hesitate to take developers’ help

Some issues require minimum interventions to resolve the problem, while others might need professional help. When updating and reinstalling the app and updating the OS version seems insufficient, contact the app developer or technical assistance team. Necessary and specific details like device OS and exactly when the issue arises, respectively, hopefully will be a deal breaker.

4. Resort to discussion forums

You are probably not alone in juggling such an error, and others are stuck with the same problem, too. Developer discussion forums are abundant with such error bugs and fixes. In this case, Apple developer forums and stack overflow can be used. Type the specific error and search for potential solutions.

5. Restore file

If the file you are looking for is deleted. The file restore option will be the only possible solution to resolve the issue. Use reliable file recovery tools like Recuva. Launch the recovery tool and follow the required steps to recover the file.

6. Fix registry keys

Faulty or broken registry keys can give errordomain=nscocoaerrordomain&errormessage=could not find the specified shortcut—& errorcode=4 error. Use reliable registry keys cleaner to fix detected issues.

Other troubleshooting steps:

Check shortcut configuration

It is pertinent to check the shortcut you are looking for is configured correctly within the application and that it is assigned to the specific action required.

Verify the existence and location of the shortcut.

Do check the shortcut resource for accessibility and location. The file associated with the shortcut should be present and accessible at its designated area.

Ensure code Implementation

From the developer’s end, review code implementation. Inspect code responsible for carrying out the required function or shortcut for potential errors and logical Issues. Improper code implementation leads to identification and execution issues.

Test in different environments

To filter the system compatibility issues, you can isolate and replicate the same command In an isolated environment. The same error absence or presence will confirm if the error is specific or ubiquitous, respectively.

Check file integrity and permission grand.

Check the accessibility of the file associated with the shortcut and if permission Is granted for the related application and its associated files.

Refer to Apple documentation.

There can be no better option than referring to the official Apple site for the NSCocoaErrorDomain-related documentation. When you follow all the solutions mentioned above for troubleshooting NSCocoaErrorDomain-related errors, you will reach the underlying issue and adequate measures to resolve it.

Preventing steps for NSCocoaErrorDomain Error

Best practices can decrease the chances of errors and increase the reliability of the application. Some preventive measures crucial for the development of the application are as follows.

1. Test shortcuts

Robust testing of all shortcuts on different iOS devices will examine the compatibility and functionality of the shortcut on various devices before it is implemented on the application.

2. Error Handling

Offer simple and effective measures for error handling. Use Straight and user-friendly voice for error messages so that the error can be easily resolved. Also, the resolution mechanism should be robust for all Apple devices.

3. Keep updating frameworks

Update Apple frameworks on time without a delay. They are often accompanied by bug fixes and allow applications to work swiftly.

4. Review code

Do code review time by time for shortcuts and NSCocoaErrorDomain errors. Frequently occurring errors and loopholes can be minimised by collaborating with other developers.

5. Follow Apple guidelines

Because NSCocoaErrorDomain is specific to Apple device’s cocoa frame, always abide by rules and guidelines as Apple dictates for shortcuts implementation.

Other common nscocoaerrordomain errors

Other than errordomain=nscocoaerrordomain&errormessage=could not find the specified shortcut.&errorcode=4 Other common error messages accompanied in NSCocoaErrorDomain may include

  1. Permission denied: Sounds familiar! Many people agree that any average tech user has at least once encountered the message that reads ‘permission denied’. It means the application does not have permission to access files or resources.
  2. File not found: Another common error is not encountered. It is the application’s failure to locate a file.
  3. Data serialisation error: This error is encountered during or deserialisation. Most commonly, it happens when the file is invalid.

Potential Causes of the Error 

When you face errordomain=nscocoaerrordomain&errormessage=could not find the specified shortcut.&errorcode=4 There can be many potential reasons for this error message. These are

  1. Using Outdated software
  2. Incomplete installation of application
  3. The file is either absent or corrupted, or permission not granted
  4. Navigation or accessibility issue
  5. Hardware ceases to function or crash
  6. Malware interrupting the system processing or when any virus attacks the system
  7. Problem with shortcut configuration and implementation.
