How to Fix Archive Utility Error 1 on Mac (Easy Guide)

Ever faced a frustrating ‘Error 1: Operation Not Permitted’ on your Mac when trying to decompress a file?

This article examines the typical issues that trigger Archive Utility Error 1, offering you clear, easy-to-follow solutions.

Whether you’re dealing with large files, unstable downloads, or pesky permissions, understanding these triggers is key to both preventing and fixing this common Mac hiccup.

What triggers Archive Utility Error 1 on your Mac?

Archive Utility Error 1 on Mac often results from several typical scenarios that interrupt the normal operation of file decompression.

This error primarily pops up when Mac users try to expand or access compressed files (like ZIP files) using the built-in Archive Utility app.

The issues that trigger this error can range from software limitations to environmental factors affecting the Mac’s operating system.

Common scenarios leading to Archive Utility Error 1

• Large file sizes: Trying to decompress exceptionally large files can exceed the capabilities of the Archive Utility, leading to Error 1.
• Unstable Internet connection: An intermittent or weak internet connection during the download of ZIP files can corrupt them, making expansion impossible and resulting in an error.
• Inadequate permissions: If the ‘Sharing & Permissions’ settings for the ZIP file are not configured correctly on your Mac, the Archive Utility might not have the necessary permissions to open or modify the file.
• Forgotten password: Encrypted ZIP files require a password to open. Forgetting this password means the file cannot be accessed, causing the utility to display Error 1.
• Corrupted files: ZIP files can become corrupted due to incomplete downloads or virus attacks. Such corruption often makes file expansion unfeasible.

Step-by-step guide to resolving Archive Utility Error 1

Encountering an “Error 1: Operation Not Permitted” when using your Mac’s Archive Utility can bring your work to a standstill. This guide provides several solutions to fix this error, ensuring your file operations return to normal swiftly.

Solution 1: Attempt manual extraction with Terminal

For those comfortable with using MacOS’s command line, the Terminal application provides a direct way to manage zip files without using the Archive Utility. Here’s how you can manually extract files:

1. Open Terminal from the Applications folder under Utilities, or you can use Spotlight search to open it.
2. Change your working directory to where the zip file is located using the cd command. For example, if your file is on the desktop, you would type cd Desktop.
3. Type unzip filename.zip and press Enter. Replace “filename.zip” with the name of your zip file.
4. The contents of the zip file will be extracted to the current directory. If the operation is successful, your files should now be accessible.

This method bypasses the Archive Utility entirely and can be a quick workaround if the graphical interface is not functioning properly.

Solution 2: Modify file permissions

Improper file permissions can also cause the Archive Utility to fail. Ensuring the zip file has the correct permissions could resolve Error 1. Here’s what you need to do:

1. Locate the problematic zip file in Finder.
2. Right-click on the file and select Get Info.
3. In the Sharing and Permissions section of the info window, ensure that your user account has Read & Write access. If not, click the lock icon, enter your administrator password, and adjust the settings.

After modifying the permissions, try extracting the file again with Archive Utility. If permissions were the issue, the extraction should now proceed without errors.

Solution 3: Repair malware-related issues with SpyHunter

If the issue persists due to possible malware affecting the process, using SpyHunter can be a practical solution.

SpyHunter can deal with a wide range of malicious apps and files, sweep them clean and restore your Mac to good working condition. Here’s how you can repair your system using SpyHunter:
