More often than not, there is a need to compress large files into zip format for easy and fast transfer. Zip is a popular archive file format that enables data compression without losing any part of the data, therefore it is widely used by both Mac and Windows users. However, it is not an all positive experience for Mac users when you try to expand zip file but encounter an error message that says Unable to expand filename.zip (Error 1 – Operation not permitted.), with the Mac Archive Utility dialogue shown as below:
Unable to expand zip file can be disheartening and discouraging, but we would guide you on how to fix Mac unzip error 1 in this article, let’s dive into it.
In this section, we will take you through the different ways and processes you can apply to fix this error.
Normally, to decompress a zipped file on Mac, you simply need to double-click the zip file, and it will automatically unzip. But if this is not the case, try unzipping your file from Terminal. Every Mac OS has a Terminal application that uses a command prompt to control the Mac. To successfully unzip your file using Terminal, follow these steps:
Step 1: Open and run Terminal. Do one of the following on your Mac:
Hold the Command and Space key to open Spotlight, type "Terminal" into the search box, then click Terminal.
Launch Finder, go to Applications > Utilities folder, then double click Terminal.
Step 2: Input the command Unzip filename.zip into Terminal and click on Enter.
Step 3: Your file will start unzipping.
Step 4 (Optional): If you get a message like "No such directory Error" or "cannot find", you might eventually have to manually use the "cd” command to change directory and unzip your files there. For example, type “cd . /desktop” in Terminal to change the directory to Desktop.
If the above method doesn’t get the job done, then try out our next fix.
