[phenixbb] Running phenix into a M1 apple processor

[Florian Nachon]

Hi Billy,

Thanx for the instructions!
I tried both the binary installer and the source installer as suggested, with the "—use-conda" flag and the installation worked well in both cases without messing up with /usr/bin.

The full installation was completed in 15 min on my M1 Max 

Also, I installed arm64 anaconda with brew, but I noticed that conda_base was still Intel. And the generated Mac app is also Intel.
I guess the explanation is that the default conda environment in the install script is osx-64 instead of osx-arm64?

You will still need a "python" somewhere in your path and the easiest way would be to install miniconda from https://docs.conda.io/en/latest/miniconda.html <https://docs.conda.io/en/latest/miniconda.html> and create a new conda environment with any python version ("conda create -n new_env python" will use Python 3.10). Activate the new environment ("conda activate new_env") and then you will have a "python" in your path. Then you can run

We have moved our dependencies to use conda so that we can more easily test different versions of Python 3. You can see that in our continuous integration output of cctbx at https://github.com/cctbx/cctbx_project <https://github.com/cctbx/cctbx_project>.
