Hey! After experiencing some problems with version R2019b on my MacBook (macOS Catalina), and knowing that these issues are well known, I tried to replace that version with the newest R2020a, but I couldn't even install it. After downloading and unzipping it, I try to execute the file InstallForMacOSX, I enter my computer's password and then the MATLAB logo appears and won't do anything more. Could anyone help me? Thanks in advance.

I'm using the current version of Catalina. Tried installing Matlab 2020a, and not matter what I did (disabling Firewall, etc.), it didn't work.

After several back and forth with Mathworks support they figured it out. I was finally able to install Matlab R2020a and R2020b on a Macbook Pro 16" which is running macOS Catalina 10.15.6.
The solution was to use Silent Install method (https://www.mathworks.com/help/install/ug/install-noninteractively-silent-installation.html) as the Graphical Installer does not work.
Modify the "installer_input.txt" to specify the destination folder, the license number, and the packages to be installed. Then make sure that when you run the command in Terminal to specify the entire path. For instance, I used the follwoing command:
/Users/xxx/Downloads/MathWorks/R2020b/install -inputFile /Users/xxx/Downloads/MathWorks/R2020b/installer_input.txt

Hi,
There are a few reasons the MATLAB installer might fail to run on MacOS,
System Requirements
Ensure that the release of MATLAB that you are attempting to install is compatible with the version of MacOS that is installed on your Mac:
System Requirements for MATLAB: Current Release
To determine the version of MacOS that you are running:
  • Click on the Apple Menu in the upper left-hand corner of the screen
  • Click "About This Mac"
Permissions
Your account must have administrative permissions to install MATLAB. If you do not have administrative permissions on your Mac, contact your system administrator.
Multiple installers
On MacOS, the installer folder contains two installers:
  • InstallForMacOSX.app
  • install
The first option is the standard graphical MATLAB installer. The second option is only for installing MATLAB from the Terminal. These are not interchangeable: if installing graphically, use InstallForMacOSX.app, if installing from the Terminal, use install. For more information on installing from the Terminal, see the MATLAB documentation:Install Noninteractively (Silent Installation)
4. Security software
Security and antivirus software may prevent you from installing MATLAB. Temporarily disable your security software, or add MATLAB to your security software's whitelist, to launch the installer.
5. Third-party archive tool
If you have installed third-party archive tools such as The Unarchiver or WinZip for Mac, make sure you extract the installer before running it. The installer cannot be run from inside the zip archive it was downloaded in, and must be extracted to a folder before it will run.

"The installer DID NOT exit gracefully ... it hung and spun until I manually killed it."
Same for me: I waited about 2 hrs before giving up and restarting the machine. To my surprise, Matlab seems to be installed and is working fine.

The R2020b has the similar issue on Catalina (macOS 10.14.x) and Big Sur (macOS 11.x.x).
I first have the full installer downloaded to the local computer.
Double clicking installer InstallForMacOSX has not response (or start and close very quickly). Right click and select Open does not work neither. Lower the security to any app does not fix it neither.
The following do not work neither:
  1. run "install" on terminal
  2. run bin/maci64/install_unix on terminal
Finally I get the installer start by running bin/maci64/install_unix_legacy on terminal.
However the last step of activation process got stuck. Run the Activate in the installed MATLAB_R2020b took long time to start, but it works at the end.
Anyone comes across the same issue.
