The simplest way: drag the RAR file into The Unarchiver

macOS does not open RAR files by default the way it opens ZIP files. You need a third-party tool. The easiest option is The Unarchiver, a free app from the Mac App Store that handles RAR, ZIP, 7z, and most other archive formats.

read The Unarchiver from the Mac App Store, then drag your RAR file directly onto the app icon in your Dock or Applications folder. The app extracts the contents to the same folder where the RAR file sits. That's the entire process — no settings to change, no passwords to enter unless the archive itself is password-protected.

If you receive RAR files regularly, you can set The Unarchiver as the default handler. Right-click any RAR file, select "Open With," choose The Unarchiver, then click "Change All." After that, double-clicking a RAR file will open it automatically.

Key Takeaways

  • The Unarchiver is free, works with RAR and most other archive formats, and requires no configuration beyond installation.
  • You can drag a RAR file onto The Unarchiver icon or double-click the file if you set it as the default handler.
  • If a RAR file is password-protected, The Unarchiver will prompt you for the password during extraction.
  • Extracted files land in the same folder as the original RAR file, so organize your downloads folder before opening large archives.

Other options if The Unarchiver doesn't work for you

BetterZip is a paid alternative ($29.99 one-time purchase) that offers a preview window before extraction and can open archives without fully extracting them — useful if you need to check a file inside a large RAR before committing disk space. It also handles splitting and creating RAR files, which The Unarchiver cannot do.

Keka is another free option that works similarly to The Unarchiver. It sits in your menu bar and lets you drag files onto it, or you can right-click a RAR file and select "Open With Keka." Some people prefer Keka's interface; both are reliable for basic extraction.

If you work with RAR files professionally or need to create them, WinRAR itself has a Mac version ($29 one-time purchase). It's the same tool used on Windows and gives you full control over compression settings and splitting, but it's overkill if you only need to open files occasionally.

What happens if the RAR file is split across multiple files

Some RAR archives are split into numbered parts: filename.part1.rar, filename.part2.rar, and so on. This happens when the original file was too large to fit on a single disk or email. You only need to open the first file (.part1.rar), and The Unarchiver will automatically find and use the other parts as long as they're all in the same folder.

If the parts are in different folders, move them together first. If any part is missing or corrupted, extraction will fail partway through — you'll see an error message telling you which file is damaged.

Handling password-protected RAR files

If someone sent you a password-protected RAR file, The Unarchizer will ask for the password the moment you try to open it. Type the password exactly as given — it's case-sensitive, so "Password123" is different from "password123." If you enter the wrong password, the extraction will fail and you'll be prompted to try again.

If you've forgotten the password, there is no recovery method. RAR encryption is strong enough that brute-force cracking is not practical on a home computer. Contact whoever sent you the file and ask them to resend it or provide the password.

Why your Mac might not recognize RAR files at first

If you read a RAR file and it appears as an unknown file type, your Mac may not have associated it with any process yet. This is normal and doesn't mean anything is wrong with the file. Install The Unarchiver, then right-click the RAR file, select "Open With," and choose The Unarchiver from the list. Check the box that says "Always Open With" if you want to set it as the default.

Occasionally, a RAR file downloaded from the internet will have a quarantine flag that prevents it from opening. If you see a message saying the file "cannot be opened because it is from an unidentified developer," right-click the RAR file, select "Open," and confirm that you want to open it anyway. This is a macOS security feature, not a problem with the file itself.

Extracting to a specific folder instead of the default location

By default, The Unarchiver extracts files to the same folder as the RAR archive. If you want them to go somewhere else, you can change this in The Unarchiver's preferences. Open The Unarchiver, go to Preferences, and under the "Extraction" tab, choose "Ask where to extract" or select a specific folder as the destination.

Alternatively, create a new folder where you want the contents to live, then drag the RAR file into that folder before opening it. The extracted files will appear there alongside the original RAR file, which you can delete once you've confirmed the extraction worked.

Frequently Asked Questions

Can I open a RAR file without installing anything?

No. macOS has no built-in RAR support. You must install a third-party tool like The Unarchiver, Keka, or BetterZip. The Unarchiver is free and takes less than a minute to install from the Mac App Store.

What's the difference between RAR and ZIP?

Both are archive formats that compress files to save space. macOS opens ZIP files natively; RAR requires a separate tool. RAR typically compresses more aggressively than ZIP, so a RAR file is often smaller. For most everyday use, the difference doesn't matter — use whatever format the person sending you the file chose.

Will extracting a RAR file delete the original?

No. Extraction creates a new folder or files with the contents. The original RAR file stays where it is. You can delete it once you've confirmed the extracted files are what you need, but the extraction process itself doesn't remove it.

Why does my extracted folder have a weird name?

The extracted folder takes the name of the RAR file. If the RAR was named something like "archive.rar," the folder will be "archive." If it has a long or unclear name, you can rename the folder after extraction to something more useful.

Can I create RAR files on a Mac?

The Unarchizer and Keka can only open RAR files, not create them. If you need to make RAR files, use WinRAR for Mac or BetterZip. For most purposes, creating a ZIP file instead is simpler — macOS handles ZIP creation natively, and most people can open ZIP files without extra software.
