Can you recommend me a best RAR extractor for Mac?

In addition to the terminal tricks, I later found several ways to do it without installing software. Let me share them with you:

1. Use online tools (open in Safari)
Although it is not a local software, some online websites can directly drag the RAR file into it to decompress it, and then download the file back. No need to install, Mac comes with Safari and can be used, which can be regarded as a disguised rar extractor for mac. However, pay attention to privacy and do not recommend decompressing sensitive files.

2. Change the extension of RAR and try to decompress it with the system archive tool
This method is unstable, but sometimes it can be used - you change .rar to .cpgz or .zip, and then double-click to try to decompress it. The macOS archive tool sometimes recognizes it successfully, like an original version of rar extractor for mac. There is no loss if it fails.

3. Decompress with the scripting language that comes with macOS (such as Python)
If you have Python installed on your Mac, you can use Python scripts to decompress RAR. For example, using libraries such as patoolib, although it is a bit troublesome, it is also a way to not use GUI software. It is equivalent to you customizing a terminal version of rar extractor for mac, which is full of geek flavor~

In general, although it is not as convenient as the third-party one-click decompression, these methods are clean, safe, and do not consume resources, and can meet the needs of rar extractor for mac in general usage scenarios~
