Q: How Can I Fix Error 1 on My Mac?
"Hi everyone, I urgently need your help, please! I can't figure out how to unzip my Zip file because I keep getting an 'error 1' message. I will gladly receive all the suggestions I can get to fix this error, thanks"

Most people opt for the Zip format when it comes to compressing files because it is a great tool that makes the transfer of files faster due to their reduced sizes. It also ensures space is not used upon systems. Therefore, it has been adopted by both Windows and Mac-based systems for convenience.

However, you can admit it is not a positive experience to try expanding your zipped file but instead get an error message that implies you cannot open the Zip file on your Mac. This error message may show like this:

"Unable to expand filename.zip (Error 1 – Operation not permitted.)"


Don't be troubled as you have come to the right place where you will learn how to fix this error.

Part 1: What Causes Archive Utility Error 1 Unable to Expand Zip File?

Several factors can be said to be the source of the archive utility error 1 which makes it impossible for you to expand your Zip file. These factors include:

  1. Instability in Network Connection: If your network connection is unstable while you are trying to extract a Zip file, then this may just be a cause for error 1. Also, instability in a network connection may occur if you close your browser before the download is completed. This only contributes to damaging your Zip file. Take note here that you may see the file in your "Download" folders but this does not mean that you can expand it.
  2. Complications from a very Large Zip File: This is another reason why you may encounter the archive utility Error 1. When you try to unzip or decompress a very large file, it could prove to be a difficulty because Archive Utility does not have the right resources to support the unzipping of very large files such as the one you may be trying to unzip.
  3. Permission not granted on Zip file: Zip files on Mac have a section called "Sharing & Permissions". If you haven't expanded this section and set it to either "Read & Write" or "Read Only", then you will not be granted permission to expand the Zip file in question. Note that if you do not run this function as an administrator, it cannot work and the error will only persist.
  4. Forgotten Password: If you set a password on your Zip file and you cannot remember it, then it may be the very reason why your Zip file is refusing to open. It is an obvious reason as a password will be required to access the file and permission denied to you if you cannot provide it.

Part 2: How to Fix Archive Utility Error 1 on Mac

In this section, you will be provided with three major solutions you can use to fix the archive utility error 1 on Mac. The solutions are aimed at unzipping the Zip file using other methods other than with archive utility. The solutions are discussed below:

Solution 1: Unzip in Terminal

"Terminal" is a Mac application that supports functions on a textbase by providing the OS with an interface that is the command line. The steps involved here comprise of the use of commands to perform the function of unzipping your Zip files. You can unzip your Zip files with these steps:

Step 1: Relocate your corrupt Zip File to Desktop so you can easily find it.

Step 2: Open and run "Terminal". There are two ways you can do this.



Step 3: Change the "Directory" to the Desktop (where you initially moved the Zip file to be unzipped). In the open "Terminal" interface, type in these commands:

cd /desktop

"cd" simply means "Change Directory"

Step 4: Unzip the Zip file by typing in this command; unzip {name of the Zip file}.zip. For instance:

unzip test.zip

Now Terminal will reveal some lines of code to indicate that the Zip file has been successfully unzipped. Your files can now be accessed on your desktop.
