MATLAB is compatible with macOS Catalina (10.15) from release R2019b onwards.
For more details on compatibility and system requirements, at the following page, click Details in the Mac column for the release you want:
Earlier versions of MATLAB do not officially support macOS Catalina. These versions may work, but MathWorks does not guarantee full compatibility with these releases on macOS Catalina.
MathWorks is currently aware of the following incompatibilities when running MATLAB on macOS Catalina:
1. Live Editor issues in MATLAB
Live Editor does not launch on macOS Catalina in MATLAB R2019a or earlier. To use Live Editor on macOS Catalina, upgrade to MATLAB R2019b or later.
2. Help Browser issues in MATLAB
Help Browser does not launch on macOS Catalina in MATLAB R2019a or earlier. Use MathWorks Online Documentation instead.
3. Property Inspector issues in MATLAB Figures
When you open the property inspector in a MATLAB figure window, MATLAB R2019b or earlier may display a blank property inspector window.
To resolve the issue, install R2019b Update 4 (or later), or upgrade to R2020a. In case the Property Inspector appears truncated, see the following MATLAB Answers Post:
4. Symbolic Math Toolbox issues
When creating symbolic variables or expressions using the Symbolic Math Toolbox, MATLAB R2019a or earlier throws the following error:
Error using mupadmex
Error in MuPAD command
To use Symbolic Math Toolbox on macOS Catalina, upgrade to MATLAB R2019b or later.
5. Issues with MATLAB Support Package for Arduino
Previously, there was an incompatibility that made it impossible to use MATLAB Support Packages for Arduino on macOS Catalina. This issue has been resolved. See the bug report below for more information:

Is Matlab 2020a compatible with macOS Catalina (10.15.4)?
I've only seen information regarding 2019b here.

Regarding the compatibility with Arduino, when is the next planned fix of Matlab to use the Arduino IDE 1.8.10 which does work with Catalina in 64bits ?

Is there any workaround for property inspector being blank? So currently with Matlab 2019b we can not change Figure properties?

I have the same issue - my OS is Catalina. Multiple attempts, same issue. Any suggestions on how to fix this?

The issues with the MATLAB Support packages for Arduino in Catalina 10.15 has been resolved in 19.2.2 version of the support package .
Please update the MATLAB Support Package for Arduino to version 19.2.2 in R2019b to resolve this.

R2019b can launch and run normally in my mac with macOS 10.15.3. But after I update to 10.15.4 it gets stuck and becomes no responding every time I open it and reinstallation also does not solve this problem. Then I find that if I change the matlab directory name in folder /''Applications'' (for example Matlab_R2019b.app to MATLAB_R2019b,app) it can start and run normally at the first opening after renaming. But it gets stuck again from the second launch. Any ideas or suggestions?
PS: When installing R2019b I changed the default installation path to "/Applications/Matlab_R2019b.app" for launch convenience

hi, I'm Vietnamese. I'm beginning with MatLab for Mac Mojave 10.14.6 but I don't have a license for it. Can you help me?

No, it's not compatible with Mac catalina, the system doesn't allow permission for webcam to start, the only solution is to start matlab from terminal

I was asked to turn off firewalls, install on safe mode all suggestions given didn’t work. I haven’t bothered since then

Did they fix the issue ?
I was able to dowload it without any issue on 02/02/2020
Do not disturb....Math Majors at work...shhh... 43% of 1,668 = (May not be 118 MB) but dont tell them that.

Yes, i have installed MatLAB 2020a to Catalina 10.15.4>
I waited for a 30 minutes before it stopped rotate the circle on 99% of installation process>
Now it works.

I have an old mac with Os X 10.11.16 El Capitan.
Is there a way to install Matlab 2019 or Matlab 2020 with a trial license on my ol Mac?
Joel Landivar on 9 Apr 2020
So, I am trying to use the Arduino Engineering Kit which comes with a Matlab Licence, however, the License allows me to install Matlab 2019a which apparently is not compatible with MacOs 10.15.4 . What should I do then? I am so dissapointed with this purchase. How can I download R2019b or R2020a if my Arduino Engineering Kit does not allow me to do it?

MATLAB 2020a works in macOS Catalina version 10.15.5, but it does not create the MATLAB icon in Launch pad as well as when I tried to make MATLAB as defult program for m files, the "MATLABWindow" icon is in disabled option. So need to select All Programs, and then selected the MATLAB icon. But still when I double click on those m files, MATLAB doesn't open the files.
If we open the MATLAB from Launchpad and then using "open" file option in MATLAB we can open m files.
So I think its not fully compatible.
