How to Open Rar File on Macbook Air

Sent a RAR archive but your MacBook Air won't open it? The built-in Archive Utility does not support RAR files, so you need a free third-party app. This guide shows exactly how to open RAR file on MacBook Air using the most reliable free tool available.

Why MacBook Air Needs Extra Software for RAR Files

Apple's Archive Utility handles ZIP and some other formats natively, but RAR requires a dedicated extractor. The Unarchiver is the simplest free option because it integrates directly into Finder and supports every common RAR variant, including password-protected and multi-part archives. No terminal commands or paid software are required.

Before starting, make sure your MacBook Air is running macOS 10.15 or later and has a stable internet connection for the initial download. Close any large applications to keep the process quick.

How to Open RAR File on MacBook Air Using The Unarchiver

1. Install The Unarchiver from the App Store

   Click the Apple menu, open the App Store, and search for "The Unarchiver". Click Get, then Install. Once the download finishes, the app appears in your Applications folder and in the Dock.

   

2. Launch The Unarchiver and set file associations

   Open The Unarchiver from Launchpad or the Applications folder. In the first screen, click "Associate" next to RAR so the app becomes the default handler for .rar files. You can leave all other formats checked or adjust them later in Preferences.

3. Locate your RAR file in Finder

   Navigate to the folder containing the RAR file. Double-click the file or right-click it and choose Open With > The Unarchiver. The extraction window appears automatically.

4. Choose extraction destination and start the process

   Select the folder where you want the extracted files to appear, then click Extract. The Unarchiver shows a progress bar. When it finishes, the new folder opens in Finder with all original files ready to use.

   

Fix Common Problems When Opening RAR Files on MacBook Air

• If the file is password-protected, The Unarchiver prompts for the password before extraction begins. Enter it exactly as provided.
• Corrupted or split RAR files often show an error. Download all parts into the same folder and try extracting the first part only.
• Should double-clicking still open Archive Utility, right-click the RAR file, choose Get Info, and change Open With to The Unarchiver, then click Change All.
• Very large RAR files may take several minutes. Keep the MacBook Air plugged in and avoid putting it to sleep during extraction.
