If you want the official CVX package to work you have to install the Matlab release for the Intel chip (OSX Intel) and run the official CVX in it. It will run through the Rosetta emulator. In other words exactly how you would do it before we made this unofficial package, or before Matlab for M1,2,3 became available. Due to emulation it is simply not as efficient as the native one.
@mcg intends to open-source CVX. Then everybody will be able to go in and fix the Gurobi-CVX interface to make it compatible with the current Gurobi Toolbox for Matlab and make Gurobi work again.
