How to install Auto-Sklearn on Mac OS (Big sur version: ✅)

#Auto-Sklearn on BigSur OSX 🖥

On the installation guide for Auto-Sklearn, the authors state: "We currently do not know if auto-sklearn works on OSX"
(Auto-Sklearn, 2021). However, there are a few steps to take that are not clear on Github/Stack, so I decided to compile
a list of those solutions and make it work for the most recent stable version of OSX (MacOS Big Sur 11.4 (20F71)).

Please feel free to follow those instructions and have fun with Auto-Sklearn. Additionally, @auto-sklearn,
if you find this solution interesting, please share the link somewhere on the installation guide.

***

> cd xgboost ; cp make/minimum.mk ./config.mk ; make -j4
> cd python-package
> sudo python setup.py install ⚠️ or if you are using python3 ⚠️ sudo python3 setup.py install

3️⃣ Installation of Auto-Sklearn:

3.1) `XGBoostLibraryNotFound: Cannot find XGBoost Library in the candidate path, did you install compilers and run build.sh
in root path?`

> cp [path_to_libxgboost.dylib] /Users/...../.conda/envs/untitled/xgboost/
