Mac users dealing with the archive utility error 1 while trying to read or extract ZIP files can get irritated. This error occurs when users try to unzip files using the built-in Archive Utility and meet file corruption or permission constraints. Archive utility error 1 usually indicates that the Mac's Archive Utility is having trouble processing a file due to faulty or incomplete downloads, invalid file formats, or lack of file permissions.

This issue might frustrate Mac users who use compressed files, mainly if the files are crucial. Fortunately, there are various methods to fix this problem without losing data. This article will explain how to solve archive utility error 1, and repair damaged ZIP files on your Mac to restore file access. 

How to Fix Archive Utility Error 1

Archive utility error 1 might prevent you from unzipping files, but there are a few ways to fix it. Protecting your data before fixing it prevents additional harm. We provide four ways to fix this issue:

1. Fix 1. Use Terminal to Unzip Files
2. Fix 2. Use Zipeg to Unzip files
3. Fix 3. Update or reinstall Archive Utility

Fix 1. Use Terminal to Unzip Files

Suppose the built-in Archive Utility fails to extract your files. In that case, you may open the Terminal program, which has a robust command-line interface and can manually unzip files without using the graphical Archive Utility. Here's how you can do it:

Step 1. Move the problematic ZIP file on your desktop for easy access.

Step 2. Search for "Terminal" in Spotlight (top-right corner) or launch it from "Applications > Utilities."

Step 3. Type "cd ~/Desktop" and press Enter.

Step 4. Press Enter after typing the command "unzip filename.zip" (replacing "filename" with the name of your file).

If successful, the terminal will provide a progress report and extract your files for the desktop.

Fix 2. Use Zipeg to Unzip Files

If Terminal does not work, you may use Zipeg, a free, open-source software for unzipping multiple archive formats such as ZIP, RAR, and 7z. Here's how you can utilize it:

Step 1. Zipeg is available for download and installation from the official website.

Step 2. Open the app and drag the ZIP file onto the Zipeg interface.

Step 3. Zipeg will reveal its contents before extracting a file.

Step 4. Select the files you wish to extract and specify the destination folder.

This approach works effectively for files that may be partly damaged but contain usable data.

Fix 3. Update or reinstall Archive Utility

Sometimes, the problem is caused by an out-of-date or malfunctioning Archive Utility. Mac's Archive Utility is updated with system upgrades, but it could be time to check for any available system updates if you've put off updating. Here's how:

Step 1. Navigate to Apple Menu > "System Preferences" > "Software Update". If an update is available, install it.

Step 2. If the issue continues, try resetting the Archive Utility by removing the preference files. In Finder, go to ~/Library/Preferences/ and remove the file com.apple.archiveutility.plist.

Step 3. Restart your Mac and attempt to open the ZIP file again.

This should refresh the Archive Utility and address minor difficulties with file corruption or permission constraints.
