How to Open 7z Files on Mac
Short answer: You can open 7z files on Mac with an archive utility such as ZipGood. ZipGood opens and extracts 7z archives, including AES-256 encrypted archives and split .7z.001 volumes, and can also create new 7z archives.
What is a 7z file?
7z is an open archive format created for the 7-Zip project. It supports very high compression ratios, solid archives, AES-256 encryption with optional header encryption, and split volumes.
macOS has no built-in support for 7z, so .7z files cannot be opened with the standard system tools.
How to open a 7z file with ZipGood
- Install ZipGood from the Mac App Store.
- Open the .7z file directly, or right-click it in the Finder and choose a ZipGood extract command.
- Choose where to extract the contents.
- Enter the password if the archive is encrypted.
- Wait for the progress indicator to finish.
Encrypted and split 7z archives
7z archives are often encrypted with AES-256, and can optionally hide their file list with header encryption. ZipGood tries your saved passwords before prompting.
Split 7z archives are named .7z.001, .7z.002 and so on. Keep the parts together and open the .7z.001 volume — ZipGood joins them automatically.
