Brew doctor warns about "Warning: A newer Command Line Tools release is available"

Hi all,

This is a first for me: after upgrading to Catalina, brew doctor warns that:

Please note that these warnings are just used to help the Homebrew maintainers
with debugging if you file an issue. If everything you use Homebrew for is
working fine: please don’t worry or file an issue; just ignore this. Thanks!

Warning: A newer Command Line Tools release is available.
Update them from Software Update in System Preferences.

I must point out that Xcode’s command line tools are already installed on their latest version:

xcode-select --install
xcode-select: error: command line tools are already installed, use “Software Update” to install updates

However everything else seems to run fine (I’m using Fish but it is the same with Bash: brew update && brew upgrade && brew cask upgrade && brew cleanup && omf doctor && omf update)

I tried re-installing Brew but it’s the same.
Here’s my brew config output:

Maybe anyone else has stumbled upon this issue already? I’d like to get as much feedback as possible before opening a new issue.



Did you try updating from the app store?

Hi @SMillerDev!

Yep, everything is (or at least seems to be) up-to-date:

Xcode version is: 11.2.1 (11B500)
xcode-select version 2370

Xcode isn’t the same as the commandline tools per se. I’d suggest running softwareupdate --list to see if they’re disconnected

Hi there,

softwareupdate --list
Software Update Tool

Finding available software
No new software available

And the command line tools seems to be installed as well:

xcode-select --install
xcode-select: error: command line tools are already installed, use “Software Update” to install updates


Turns out that Apple sometimes fails to provide these via Software Update, requiring you to download them yourself.

The version of clang being looked for is 1100.0.33.12 & yours is reporting as 1100.0.33.8. Probably not that much of an issue.

❯ clang -v     
Apple clang version 11.0.0 (clang-1100.0.33.12)

Hi there, I’ve been having some trouble with this exact issue! I ran brew config to find out my Command Line Tools were not at version 11.2, so I also tried to update via the app store, via the command line, and nothing worked. Then I went to the developer website for apple and downloaded the latest non-beta for Command Line Tools, version 11.2. Instantly fixed.


Btw, here’s the link:


Exactly the same issue here!

Same issue here. I wonder if Apple is aware ?
