MATLAB: MATLAB R2020a won’t even install on macOS Catalina

catalinamacMATLABr2020a

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.

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.
