1. Aug 21, 2018  Quite simply, Homebrew is a computer script (based on the Python programming language). You can install it on your Mac and then use it to.
  2. Searching “homebrew mac” will return it pretty near the top. It, like all package managers imports a lot of stuff with each new application you install. But, that can be helpful if you want to.

I've removed advertising from most of this site and will eventually clean up the few pages where it remains.

While not terribly expensive to maintain, this does cost me something. If I don't get enough donations to cover that expense, I will be shutting the site down in early 2020.

Homebrew’s package index. Homebrew Formulae is an online package browser for Homebrew – the macOS (and Linux) package manager.

Step-by-step instructions are provided here to install Homebrew itself and then install Homebrew packages based on the name of formulae specified for installation in a command such as: brew install wget.

I've read several glowing reviews of Homebrew recently, so I checked it out. It does some things the right way, for example putting everything you install in its own directory and then symlinking to /usr/local. You don't need sudo to install things after installing Homebrew itself (but you DO need to be an admin account), so that's a good thing too. But..

Let's take it for a spin. First problem: I don't run as an admin account, so I had to install Homebrew from an account that does have admin ability.

Well, that was easy. Now let's go get something else. I switched back to my normal, non-admin account.

Homebrew For Mac

Oops. That's not going to work. The perms on the Homebrew stuff are all for the admin user. So I removed brew using a script I found in their FAQ. I then temporarily gave my normal account admin ability, rebooted, and reinstalled as myself. Sigh.. that ran into dozens of errors:

Obviously the removal process didn't work very well. That's unfortunately all too common. People tend to neglect removal needs as they change their main code.

Still, some things looked better:

Whatever that means.. meaningless messages are also far too common. But at least it seemed to be trying.

Let's try something else:

OK, let's make that directory by hand using my admin account, change its perms and try again.

Ahh, so this isn't going to work. It sets stuff up in the admin group. I suppose I could try ACL's, but at this point I just don't care enought to fool with it any more. If I want to install something from Homebrew, I'll just have to switch to the admin account.

So it works that way, though that's inconvenient for me. If you run with admin powers, this does seem to have value, but it's too clumsy for me.

See Homebrew without sudo for a possible fix; I did not try that.
