Fix 3: Decompress the Zip File using Terminal

When unable to unzip a file by double-clicking, you can utilize a command in the Mac Terminal to extract the contents of the zip file and resolve the "unable to expand zip file Mac error 79."

Utilizing the Terminal provides the advantage of unzipping large files that might surpass the capabilities of the Archive Utility. It can also help in opening corrupted zip files that the Archive Utility is unable to expand on a Mac.

Here's a step-by-step guide on how to extract files using the Terminal: 1. **Open Terminal**: First, you need to access the Terminal application. You can do this by using Spotlight Search (press Command + Space), typing "Terminal," and then pressing Enter. 2. **Navigate to the folder containing the archive**: In the Terminal window, use the `cd` (change directory) command to navigate to the folder where your compressed file is located. For example: ``` cd /path/to/your/folder ``` Replace "/path/to/your/folder" with the actual path to the folder. 3. **Check the file format**: Determine the type of compression used for the file. Common formats include .tar, .gz, .bz2, .xz, and .zip. You can check the file extension or use the `file` command in Terminal. For instance: ``` file filename.tar.gz ``` This will display the file format. 4. **Extract the file**: Depending on the file format, use the appropriate command: - **.tar**: Use `tar -xvf filename.tar` - **.gz**: If it's a .tar.gz file, use `tar -xzf filename.tar.gz` - **.bz2**: If it's a .tar.bz2 file, use `tar -xjf filename.tar.bz2` - **.xz**: If it's a .tar.xz file, use `tar -Jxf filename.tar.xz` - **.zip**: Use `unzip filename.zip` 5. **Wait for the extraction process**: The Terminal will show the progress of the extraction. Once completed, you'll see a message like "tar: Exiting with failure status due to previous errors" (for tar commands) or "Archive: filename.zip" followed by "inflating: filename" for zip files. 6. **Verify the extraction**: Navigate to the extracted folder and ensure that all files have been successfully decompressed. That's it! You've now extracted the files using the Terminal.

Step 1. Open "Terminal" by going to "Finder"

Step 2. Next, go to "Applications"

The Terminal will then start the extraction process. If this command doesn't unzip your file and instead results in an error message like "No such file or directory" or "cannot find," proceed with the following steps:

Step 1. Enter the "cd" command into the "Terminal," which lets you navigate directly to the directory where the zip file is situated. For example, if your zip file is in the Downloads folder, type the following command: cd ~/Downloads

Step 2. Press "Return."

Step 3. Next, type unzip followed by a space, and then drag your zip file into the "Terminal" window.
