Just in case some of you use homebrew to install/update SWI-Prolog on Mac OS. I created a tap that also supports --devel flag (recently removed from the official homebrew core). The latest versions are already there (8.0.1 and 8.1.1), and I keep them updated. Let’s see how the community develops the official formula in the long run, but in the meanwhile it’s an ok workaround.

```
brew tap likelion/tap
brew install swipl
brew install swipl --devel
```

Thanks. I tried to submit an official homebrew formula for the new CMake build. It was never merged. I wanted a version with the gui tools, reasoning that Mac is primarily a development platform rather than a deployment platform. The Brew people do not like X11 (I can agree as it is bulky and buggy on the Mac).  
I lost interest. Anyway, if someone wants to pick it up, there discussion is at [https://github.com/Homebrew/homebrew-core/pull/33706#issuecomment-446742641](https://github.com/Homebrew/homebrew-core/pull/33706#issuecomment-446742641)
