I'm trying to run brew install unrar on mac os Big Sur and I'm getting the following error:

Updating Homebrew...
==> Auto-updated Homebrew!
Updated 1 tap (homebrew/cask).
==> Updated Casks
Updated 1 cask.

==> Searching for similarly named formulae...
Error: No similarly named formulae found.
Error: No available formula or cask with the name "unrar".
==> Searching for a previously deleted formula (in the last month)...
Error: No previously deleted formula found.
==> Searching taps on GitHub...
Error: No formulae found in taps.

Please advise on how I can resolve this.

Use brew install rar to install both the rar and unrar binaries.

See cask for details:

https://github.com/Homebrew/homebrew-cask/blob/master/Casks/rar.rb

Just use brew install rar instead of brew install unrar

For rar files

Try using Homebrew...

In a terminal type:

brew install rar

Now to use it just navigate to your file directory and type:

  • To view the rar file:
unrar l <filename>
  • To extract the rar file in the same location:
unrar x <filename>
  • To extract the rar file in the desired location:
unrar x <filename>

In case you face any permission issue: Developer cannot be verified.
'rar' cannot be opened because the developer cannot be verified.
Follow this process:
Open System Preferences -> Security and Privacy -> General -> Click the lock to make changes.

For zip files

In the terminal (at .zip location):

unzip <filename>

Go to mac's system settings/privacy&security/scroll down to security allow unrar app, you should see it as blocked.

Using the default rar formulae may cause permission errors in recent macOS versions. So you can install unrar using this custom formulae:

brew install carlocab/personal/unrar

See discussion about it here: Unrar has been removed, but I need unrar. Alternatives?.
