The fastest way to open a RAR file on Mac
The easiest method is to read and install The Unarchiver, a free app from the Mac App Store. Once installed, right-click any RAR file, select "Open With," choose The Unarchiver, and the file extracts automatically. The Unarchiver handles RAR files without extra steps or paid upgrades — it just works.
If you prefer not to install anything, you can upload the RAR file to a free online service like ezyZip or CloudConvert, extract it in your browser, and read the contents. This takes longer but requires no software on your Mac.
A third option is BetterZip, a paid app ($20) that opens RAR files and shows you what's inside before extracting. Most people do not need this — The Unarchiver covers the common case.
Key Takeaways
- The Unarchiver is free, works with RAR files when ready after installation, and requires no configuration.
- Once installed, you can right-click any RAR file and extract it in one step without opening an app manually.
- Online extraction services like ezyZip work if you do not want to install software, though they are slower and require uploading your file.
- Mac's built-in Archive Utility does not handle RAR files, so a third-party tool is necessary.
Why Mac cannot open RAR files by itself
Mac's built-in Archive Utility only handles ZIP, GZIP, BZIP2, and 7Z formats. RAR is a separate compression format that Apple never included in the operating system. This is not a limitation of your Mac — it is straightforward a format choice, like how some programs save as DOCX and others as PDF.
When you receive a RAR file on Mac, the system does not know what to do with it. You need a separate tool that understands the RAR format and can decode it back into the original files.
Installing and using The Unarchiver
Open the Mac App Store, search for "The Unarchiver," and click Install. The app is free and maintained regularly. Once installed, it runs in the background — you do not need to open it manually.
To extract a RAR file, right-click it in Finder, hover over "Open With," and select The Unarchiver from the menu. The file extracts to the same folder, usually in a few seconds. If you have multiple RAR files, you can select them all, right-click, and extract them at once.
The Unarchiver also handles split RAR files — sets of files named like "archive.part1.rar," "archive.part2.rar," and so on. Select the first file in the sequence, right-click, and extract. The Unarchiver finds the other parts automatically.
Using online extraction if you do not want to install software
Go to ezyZip.com or CloudConvert.com in your web browser. Both sites let you upload a RAR file, extract it online, and read the contents without installing anything on your Mac.
The process is straightforward: click the upload button, select your RAR file, wait for the extraction to finish (usually 30 seconds to a few minutes depending on file size), then read the extracted files. This method works for files up to a certain size — ezyZip handles files up to 200 MB for free, and CloudConvert handles larger files but may ask you to create an account.
The downside is that your file travels over the internet to a server you do not control. If the RAR file contains sensitive information, this method is not the right choice.
What to do if extraction fails
If The Unarchiver cannot open a RAR file, the file may be corrupted or incomplete. Try downloading it again from the source — sometimes files do not transfer fully over the internet.
If the file is split (multiple .part files) and you are missing one, extraction will fail. Check that you have all the parts in the same folder before trying again. If you are using an online service and it fails, try The Unarchiver instead, or vice versa — sometimes one tool handles a damaged file better than another.
If the RAR file is password-protected, The Unarchiver will ask you for the password when you try to extract. If you do not have the password, you cannot open the file.

Frequently Asked Questions
Can I open a RAR file without extracting it?
BetterZip lets you browse inside a RAR file and extract only certain files instead of everything at once. The Unarchiver extracts the entire archive. If you need to see what is inside before extracting, BetterZip is worth the $20.
What happens to the original RAR file after I extract it?
The RAR file stays on your Mac. Extraction creates a new folder or files with the contents — it does not delete the original. You can delete the RAR file yourself once you have confirmed the extracted files are what you need.
Can I create RAR files on Mac?
The Unarchiver only extracts RAR files; it does not create them. If you need to make a RAR file, use BetterZip (paid) or an online service. Most people use ZIP instead, which Mac can create natively.
Is it safe to extract files from the internet?
Extracting is safe — the risk is in what the files contain. Before opening any extracted file, make sure you trust the source. Malware can hide inside any file type, whether it came in a RAR, ZIP, or any other format.
Why would someone send me a RAR file instead of a ZIP?
RAR files compress slightly better than ZIP, so they are smaller for the same content. Some people also use RAR for split archives — breaking a large file into multiple smaller pieces for easier transfer. ZIP is more common on Mac because it is built in.
