Cakebrew says "Error: Calling 'brew search' with no arguments to output formulae is disabled!" I am a new macOS user. I just did a fresh install on an A1398 MacBook Pro and upgraded to Big Sur. As I am used to package managers, I decided to investigate Homebrew and Cakebrew to go along with it. I was able to install Homebrew, with no warnings or errors. Then, I installed Cakebrew with the brew command.
Upon launching Cakebrew, the &quot;All Formulae&quot; list reports the following error:

Error: Calling 'brew search' with no arguments to output formulae is disabled! Use 'brew formulae' instead.

The same error occurs if I execute brew search on the command-line.
Your error is from the brew command, and Cakebrew is just reporting it. You can see the error if, in Terminal, you do: brew search.  I suspect that your Cakebrew has not kept up with changes to the brew command.
The version of Cakebrew installed via HomeBrew is version 1.2.5. I have always used that from Cakebrew web site. From there you will get version 1.2.7.  Try that.  The &quot;All Formulae&quot; list works for me.
Edit: The question was also asked here github. The recommendation is to update to version 1.3.  This fixes the issue.
