MATLAB is compatible with macOS Catalina (10.15) from release R2019b onwards.
For more details on compatibility and system requirements, see under the Mac column in the following link:
Earlier versions of MATLAB do not officially support macOS Catalina. They may work, but we do not guarantee full compatibility with these releases on macOS Catalina.
We are currently aware of the following incompatibilities when running MATLAB on macOS Catalina:
1. Live Editor issues in MATLAB
Live Editor will 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 will not launch on macOS Catalina in MATLAB R2019a or earlier. Use our Online Documentation instead.
3. Property Inspector issues in MATLAB Figures
When you open the property inspector in a MATLAB figure window, it may display a blank property inspector window in MATLAB R2019b or earlier.
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 will throw 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 has been an incompatibility which 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:

IF you have any antivirus or firewall, disable those. You can also try starting the installer as an admininstrator or sudo in Terminal.

I think they are indicating that they have been successful in using MATLAB on Catalina on their systems. But it is still a bit odd, so... ??
None of the people answering Yes appear to have any other postings, so I cannot cross-check to see if they have mentioned using Mac before.

You will either need to upgrade to High Sierra or later, or you will need to use R2019a or appropriate earlier versions. Release R2019b is not supported for Sierra.

Mathworks is not able to obtain that level of information from Apple. They do try.
Apple has been making a lot of changes recently without giving industry enough time to adjust or even giving enough information about the interactions of the changes.
Apple has been quite difficult to get information from these days.
Bradley Evans
Bradley Evans on 29 Mar 2020
Apple is pretty snooty these days. Hey, when you're Number 1, why make anyone happy? Best to buy a PC, cut the costs of purchasing a computer by 80%, and maybe Matlab will work on your PC. Apple was best back when Jobs and Wozniak had it. Tim Cook? How about Tim Crook?

43% is relative to everything that was queued to be downloaded; 118 is related to the current file.

Of course. When you first open up Matlab, you need to reboot your computer. Then press the button of matlab. You need wait since it will cost some time. The interface is not smooth. Then you need to change the JAVA heap size to maximum. May it will be better. Also you can shut down the code mannger in general setting.

It is a sequence of letters and numbers that in combination with the identifiers of your hardware is used to authorize MATLAB to run on your computer.

I suggest trying to move your preferences directory aside so that MATLAB recreates it. The preferences directory should be Library/Application Support/MathWorks/MATLAB/R2019b under your home directory. Rename that to something else as an experiment.

A resounding NO!
I tried to download the ENTIRE Matlab package for Mac TWICE. It failed both times. It gets to the very end, 99% or 100% complete. Them the Matlab window goes white, and a turning, spoked wheel goes round and round (the "spin cycle"), which is executed endlessly. Then, wanting to get out of this, we hit the red exit button, which asks us, "Do you really want to quit?", for which we answer, "Yes." Then, the program exits and we are left with a Matlab 2020a application on our "Applications" folder which won't boot up. We try to get rid of it, and then we are told by the Mac OS, "Can't close the program, becuase it is open." Hence, RESTART. Hence, remove Matlab 2020a application from the "Applications" folder upon RESTART, and begin again. It does end up like a wash cycle: Rinse and Repeat and get the same thing all over again. NOTHING!
So, to answer the question, "NO!" Don't download Matlab 2020a for Mac Catalina. IT JUST WON'T WORK!
I have Catlina 10.15.4, by the way. In conclusion, it's best to get a PC!

No! R2014b was the last release supported on Mountain Lion. You might be able to get away with a couple of releases after that, but you should expect it would fail by R2018a or so if not earlier.

When you phrase the question that way, I think that the only possible answer for you is that R2019b and R2020a are not compatible with MacOS Catalina.
Both R2019b an R2020a are intended to be compatible with MacOS Catalina, but MacOS Catalina introduced a lot of changes and it has not been possible to fix all of the problems yet. At least one incompatibility remains, so if a Yes or No answer is required, then the answer would have to be No.
By the way: if you were to ask "Is wheat compatible with humans or not?" and those are the only two answers permitted, the answer would have to be "not". Wheat has been grown by humans for close to 12000 years, and agricultural selection has been going on for that time, making wheat more and more compatible with humans, but there is still a portion of humans that are allergic to wheatgerm -- at least one incompatibility remains for about 0.21% of the population, so if we are forced to say "Yes" or "No" for compatibility then we would have to say "No" because otherwise we would be promising that absolutely no one would encounter a wheat allergy.

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

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?

I am not familiar with that kit or the licensing of it.I notice from the web page for it that,
"MATLAB, Simulink, Stateflow, and ten other add-on products are included in the kit at no extra cost. The Arduino Engineering Kit includes a one-year license of these products for one individual. "
and
"The Arduino engineering kit includes a one year license for Matlab and Simulink for free. If you wish to continue using Matlab/Simulink after the trial period, you can purchase a new license by following the link below:"
I am concerned about the possibility that the license might already have only at most 5 1/2 months remaining before it expires.
Normally if someone arranges a 1 year license, that would either be relative to the time of activation or else would have fixed dates (e.g., aligned with a school year.) I am surprised it would get you an R2019a license.
Hmmm, buried in the FAQ I see they say R2018a !

Hello,
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.
