7-Zip for mac alternatives for opening rar files

If you're looking for a good 7-zip for mac alternative to replace the existing decompression software, then The Unarchiver app is definitely worth checking out. It's an open source decompressor for macOS, and the best thing about it is that it's completely free. The format of the program is compatible with 7z, ZIP, RAR and in terms of settings, I personally recommend setting it as the default decompressor. 

How to use 7-Zip for Mac alternative

1. Double-click the software and click File > Preferences in the menu bar. In the Archive Formats tab, check All Formats 

2. Find the file you want to unzip in the Finder, double-click the file, and the tool will unzip it to the current directory automatically. 

3. If you don't have Default Unzip set, right click on the file and select Open > The Unarchiver to find the file you want to unzip, double click on it and select the format you want to unzip it in, the tool will unzip it automatically. 

4. Check the unzipped file in the Finder to make sure it's complete.

After the setting is completed, you only need to double-click the compressed file in the Finder, and the system will automatically call the Unarchiver to open rar file on mac, which greatly improves the decompression efficiency and makes the process of file handling smoother and more convenient. It's worth noting that The Unarchiver only focuses on decompression at the moment, and doesn't have the ability to compress files.
