Why, when trying to install MATLAB R2020b on Apple Silicon machines, does running the MATLAB installer generate this error:
Further, if the install is attempted from the terminal, an error similar to this is generated:
line 90: installer_1925/bin/maci64/InstallForMacOSX: Bad CPU type in executable
find: installer_1925: No such file or directory
find: installer_1925/archives: No such file or directory
find: installer_1925/archives: No such file or directory

Running x86-based applications like MATLAB and its installer on the new Apple Silicon Macs requires Apple's Rosetta 2 emulation software to be installed first. If it has not been previously installed, running the MATLAB R2020b installer will generate the above permissions error.
To install Apple's Rosetta 2 software, please open a Terminal window (found in Utilities) and run the following instruction:
sudo /usr/sbin/softwareupdate --install-rosetta
Once the Rosetta 2 installation has completed, you will be able to run the MATLAB installer in the normal way.
