That frustrating moment when your Mac throws an Errordomain=nscocoaerrordomain&errormessage=не удалось найти указанную быструю команду.&errorcode=4 error can stop your workflow dead in its tracks. This Russian error message translates to “could not find the specified shortcut” and typically appears when macOS can’t locate a file, resource, or shortcut that an application is trying to access. Unlike typical errors, this one combines multiple languages, making it particularly bewildering for users worldwide.
You’ll typically encounter this roadblock after system updates, file migrations, or when opening apps with broken references. The error effectively halts operations until you address the underlying shortcut problem. Let’s dig into what’s happening behind this cryptic message and fix it for good with proven solutions that go beyond the basics.
What is Errordomain=nscocoaerrordomain&errormessage=не удалось найти указанную быструю команду.&errorcode=4 Error?
The Errordomain=nscocoaerrordomain&errormessage=не удалось найти указанную быструю команду.&errorcode=4 isn’t just gibberish—it’s a highly specific error from Apple’s Cocoa framework that powers macOS applications. Let’s break down this technical message:
- NSCocoaErrorDomain: Indicates the error originates within Apple’s Cocoa application environment
- не удалось найти указанную быструю команду: Russian phrase meaning “could not find the specified shortcut”
- ErrorCode=4: References error code 4 in the NSCocoaErrorDomain, specifically designating a “file not found” condition
When this error happens, macOS tells you that an application attempted to access a shortcut (alias in Mac terminology) that doesn’t exist at the expected location. The system looked for a file or resource and came up empty-handed, leaving your app stuck in limbo.
ErrorDomain = NSCocoaErrorDomain
ErrorMessage = не удалось найти указанную быструю команду.
ErrorCode = 4
The multilingual nature of this error often results from system language inconsistencies, particularly on machines that have been used with multiple language settings or after migration from different language environments.
Common Causes of the Errordomain=nscocoaerrordomain&errormessage=не удалось найти указанную быструю команду.&errorcode=4 Error
1. Deleted or Moved Target Files
The most straightforward cause is that the file or application the shortcut points to has been deleted, moved, or renamed. macOS shortcuts contain direct references to their targets’ locations, and any change breaks that link.
Problematic Pattern:
// Application trying to access a file via a broken alias
let fileURL = NSURL(fileURLWithPath: “/Users/username/Documents/ImportantFile.txt”)
do {
let resourceValues = try fileURL.resourceValues(forKeys: [.isAliasFileKey])
if resourceValues.isAliasFile == true {
// This will trigger the error if the target doesn’t exist
let resolvedURL = try URL(resolvingAliasFileAt: fileURL as URL)
// Process file…
}
} catch {
print(“Error accessing file: \(error)“)
}
Solution:
// A more robust approach with proper error handling
let fileURL = NSURL(fileURLWithPath: “/Users/username/Documents/ImportantFile.txt”)
do {
let resourceValues = try fileURL.resourceValues(forKeys: [.isAliasFileKey])
if resourceValues.isAliasFile == true {
// Try to resolve, but handle missing targets gracefully
do {
let resolvedURL = try URL(resolvingAliasFileAt: fileURL as URL)
// Process file…
} catch {
// Create a new reference or notify user
print(“The shortcut target is missing. Please select a new file.”)
// Code to prompt user for new location
}
}
} catch {
print(“Error accessing file: \(error)“)
}
2. Corrupted Alias Database
macOS maintains alias databases that can become corrupted after system crashes or improper shutdowns, leading to this error even when files seemingly exist.
Problematic Pattern:
// Relying on system alias resolution without verification
func openDocumentFromAlias(aliasPath: String) {
let url = URL(fileURLWithPath: aliasPath)
NSWorkspace.shared.open(url) // May fail with errorcode=4
}
Solution:
// Verify alias integrity before attempting to use it
func openDocumentFromAlias(aliasPath: String) {
let url = URL(fileURLWithPath: aliasPath)
// Check if file exists before attempting to open
var isDirectory: ObjCBool = false
if FileManager.default.fileExists(atPath: url.path, isDirectory: &isDirectory) {
NSWorkspace.shared.open(url)
} else {
// Attempt to repair the alias or create a new one
rebuildAliasReference(for: url)
}
}
func rebuildAliasReference(for url: URL) {
// Alias rebuild logic here
// This might involve prompting the user or searching known locations
}
3. Language Inconsistencies Causing Errordomain=nscocoaerrordomain&errormessage=не удалось найти указанную быструю команду.&errorcode=4
This error often appears with Russian text because of system language conflicts. This typically happens when:
- The Mac was previously used with Russian system settings
- You’ve migrated from a Russian-localized machine
- Apps were installed from Russian sources but run on a different language system
Problematic Pattern:
// Hard-coded localization that doesn’t match system language
func displayErrorMessage(for error: Error) {
if let nsError = error as NSError? {
let message = NSLocalizedString(“FILE_NOT_FOUND_KEY”, comment: “”)
displayAlert(message: message)
}
}
Solution:
// Properly handle cross-language errors
func displayErrorMessage(for error: Error) {
if let nsError = error as NSError? {
// Extract the error domain and code
let domain = nsError.domain
let code = nsError.code
// Provide a language-neutral response based on error properties
if domain == NSCocoaErrorDomain && code == 4 {
displayAlert(message: “The shortcut target file could not be found. It may have been moved or deleted.”)
// Offer recovery options
offerRecoveryOptions()
} else {
// Handle other errors
let message = NSLocalizedString(“GENERIC_ERROR_KEY”, comment: “”)
displayAlert(message: message)
}
}
}
4. Permissions Issues
Sometimes the file exists, but the application lacks permission to access it, triggering the same error code.
Problematic Pattern:
// Attempting to access files without checking permissions
let fileURL = URL(fileURLWithPath: “/Users/username/Documents/RestrictedFile.txt”)
do {
let data = try Data(contentsOf: fileURL)
// Process data…
} catch {
print(“Error: \(error)“) // This might show errorcode=4
}
Solution:
// Check permissions before attempting access
let fileURL = URL(fileURLWithPath: “/Users/username/Documents/RestrictedFile.txt”)
let fileManager = FileManager.default
// Verify read permissions first
if fileManager.isReadableFile(atPath: fileURL.path) {
do {
let data = try Data(contentsOf: fileURL)
// Process data…
} catch {
print(“Error reading file: \(error)“)
}
} else {
// Handle permission issues specifically
print(“Permission denied. Request access to this file.”)
// Code to request permission or notify user
}

How to Diagnose Errordomain=nscocoaerrordomain&errormessage=не удалось найти указанную быструю команду.&errorcode=4 Error
Follow this systematic approach to pinpoint the exact cause of your error:
Step 1: Enable Verbose Logging
First, capture detailed error information by enabling verbose logging:
# In Terminal, enable verbose logging for the problematic application
defaults write com.example.applicationbundle NSDebugEnabled YES
defaults write com.example.applicationbundle NSZombieEnabled YES
This will produce logs like:
2025-04-22 14:32:15.342 [AppName] ERROR: Failed to resolve alias file at path ‘/Users/username/Documents/MissingFile.txt’
Domain: NSCocoaErrorDomain
Code: 4
Description: не удалось найти указанную быструю команду.
Step 2: Trace the Shortcut Path
Use Terminal to identify where the shortcut is pointing:
# For .alias files
mdls -name kMDItemWhereFroms /path/to/your/shortcut.alias
# For .webloc files
defaults read /path/to/your/shortcut.webloc
Step 3: Check File System Status
Verify file system integrity, as corruption can cause this error:
# Run First Aid through Terminal
diskutil verifyVolume /
Step 4: Test with a New User Account
Create a test user account to determine if the issue is user-profile specific:
# Create a test user via Terminal
sudo sysadminctl -addUser testuser -password TestPass123 -admin
If the error doesn’t occur in the test account, the problem lies in your user profile’s application settings or shortcuts.

Solution 1: Smart Alias Resolution System
This reusable Swift class provides intelligent handling of broken shortcuts:
import Foundation
import AppKit
class SmartAliasResolver {
enum AliasResolutionError: Error {
case aliasTargetMissing
case aliasCorrupted
case permissionDenied
case unknown(Error)
}
// Main method to safely resolve and open an alias file

// Target missing – try recovery options
attemptToRecoverMissingTarget(originalAlias: fileURL) { result in
completion(result)

}
} catch {
// Could not resolve alias
attemptToRepairAlias(at: fileURL) { result in
completion(result)
}
}
} catch {
// Error checking if it’s an alias
completion(.failure(.unknown(error)))
}
}
// Attempt to recover a missing target file
private static func attemptToRecoverMissingTarget(originalAlias: URL, completion: @escaping (Result<URL, AliasResolutionError>) -> Void) {
// Extract the target filename from the alias metadata if possible

if let foundURL = foundURL {
// Found a likely match
// Create a new alias pointing to the found file
do {
try createNewAlias(from: originalAlias, to: foundURL)
completion(.success(foundURL))
} catch {
completion(.failure(.unknown(error)))
}
} else {
completion(.failure(.aliasTargetMissing))
}
}
} catch {
completion(.failure(.aliasCorrupted))
}
}
// Search for possible targets based on name or other metadata
private static func searchForPossibleTargets(originalAlias: URL, completion: @escaping (URL?) -> Void) {
// In a real implementation, this would:
// 1. Extract target filename from alias metadata
// 2. Use NSMetadataQuery to search for files with matching name
// 3. Use similarity metrics to find the most likely match
// Simplified placeholder
let query = NSMetadataQuery()
// Configure query based on extracted metadata
// Return the best match or nil
completion(nil)
}
// Create a new alias file replacing the corrupted one
private static func createNewAlias(from originalAlias: URL, to targetURL: URL) throws {
// Backup the original
let backupURL = originalAlias.appendingPathExtension(“backup”)
try FileManager.default.copyItem(at: originalAlias, to: backupURL)
// Create new alias data
var bookmarkData: Data?
do {
bookmarkData = try targetURL.bookmarkData(options: .suitableForBookmarkFile, includingResourceValuesForKeys: nil, relativeTo: nil)
} catch {
throw error
}
// Write the new alias file
try FileManager.default.removeItem(at: originalAlias)
try URL.writeBookmarkData(bookmarkData!, to: originalAlias)
}
// Attempt to repair a corrupted alias
private static func attemptToRepairAlias(at aliasURL: URL, completion: @escaping (Result<URL, AliasResolutionError>) -> Void) {
// Implementation would attempt to:
// 1. Read any recoverable data from the corrupted alias
// 2. Try alternative resolution methods
// 3. Potentially prompt user for manual resolution
// Simplified placeholder
completion(.failure(.aliasCorrupted))
}
}
// Usage example:
func openDocument(aliasPath: String) {

NSWorkspace.shared.open(resolvedURL)
case .failure(let error):

// Show UI to browse for replacement
promptUserForReplacement(originalPath: aliasPath)
case .aliasCorrupted:
// Offer to create a new alias
promptToCreateNewAlias(replacingPath: aliasPath)
case .permissionDenied:
// Request permission
requestFileAccess(for: aliasPath)
case .unknown(let underlyingError):
// Log and show generic error
print(“Unknown error: \(underlyingError)“)
displayGenericError()
}
}
}
}
Solution 2: Rebuild Launch Services and Alias Databases
This Terminal-based solution resets the system’s record of applications and file associations:
#!/bin/bash
# Script to fix Errordomain=nscocoaerrordomain error 4
# Save as fix_alias_error.sh and run with bash fix_alias_error.sh
echo “Fixing NSCocoaErrorDomain error 4 (Missing shortcut target)…”
# Step 1: Rebuild LaunchServices database
echo “Rebuilding LaunchServices database…”
/System/Library/Frameworks/CoreServices.framework/Frameworks/LaunchServices.framework/Support/lsregister -kill -r -domain local -domain system -domain user
# Step 2: Clear application state
echo “Clearing application state…”
defaults delete com.apple.finder
# Step 3: Reset alias resolution cache
echo “Resetting alias cache…”
defaults write com.apple.desktopservices DSDontWriteNetworkStores true
defaults write com.apple.desktopservices DSDontWriteUSBStores true
# Step 4: Restart Finder to apply changes
echo “Restarting Finder…”
killall Finder
echo “Done! Please restart your Mac to complete the process.”
