Comparing PyMOL on a M1 MacBook Pro Max with Intel MacBookPro (2016)
After a little hunting I found an open-source version of PyMOL for M1 Macs on Home-brew. Installation didn't go as smoothly as I expected so I thought I'd outline the process I went through.
Installing Homebrew on M1 Mac
The install script is available here https://brew.sh
/bin/bash -c "$(curl -fsSL https://raw.githubusercontent.com/Homebrew/install/HEAD/install.sh)"
This ran as expected but when I looked I could not see the usual installation. It turns out this script installs Homebrew to its preferred prefix (/usr/local for macOS Intel, /opt/homebrew for Apple Silicon). I presume this is so folks can have a separate installation for Rosetta. You can see the hidden folders in the Finder by pressing "Shift-Command-." (Shift and Apple keys and full-stop).
So I checked that my PATH included the correct folder.
echo $PATH /Users/chrisswain/miniconda3/bin:/Users/chrisswain/miniconda3/condabin:/opt/homebrew/bin:/opt/homebrew/sbin:/usr/local/bin:/usr/bin:/bin:/usr/sbin:/sbin:/opt/X11/bin:/Library/Apple/usr/bin:/Applications/moe2020/bin:/Applications/moe2020/bin
Then searched for Pymol
brew search pymol ==> Formulae brewsci/bio/pymol
Then tried to install
brew install pymol
And got this error

Sorry :(
So uninstalled cmake and reinstalled.
brew uninstall cmake brew install cmake brew install pymol
All seemed to work fine
Then in Terminal type pymol
I tried a few simple tasks
Open a local copy of 3j3q.cif
Intel MacBook Pro took 16 seconds
M1 MacBook Pro took 6 seconds
Create surfaces and export as poverty
Imported a local copy of 7n30, added hydrogens and coloured ribbon by secondary structure.
Intel MacBook Pro took 54 seconds
M1 MacBook Pro took 36 seconds
Export to POV-Ray
Intel MacBook Pro took 23 seconds
M1 MacBook Pro took 13 seconds
