- (Recommended) Back up the original JRE folder <matlabroot>/sys/java/jre/maci64
- Replace the original JRE folder <matlabroot>/sys/java/jre/maci64/jre with <jre_root>/Contents/Home
- Confirm the operation by finding “java” executable in the path <matlabroot>/sys/java/jre/maci64/jre/bin/java.
- Launch MATLAB and verify the JRE version with “version -java”. The output should include “AdoptOpenJDK”.
Why do buttons, apps, or the editor in MATLAB respond slowly or hang on MacOS?

I am using MATLAB R2019a and MATLAB R2018b with MacOS High Sierra, and I am seeing performance issues with many UI interactions such as the following:
- Really slow responses (4-5 seconds) when pressing buttons such as 'Run' and 'New'
- Lag when re-positioning the text cursor in a script file via mouse click (or highlighting sections of text)
- Lag or a freeze when interacting with some apps such as the Color Thresholder or Image Viewer apps
I did not face these issues with MATLAB R2018a
How do I solve this issue?

This issue can be caused by the incompatibility of Magnet App, BetterTouchTool, or similar window-snapping apps with MATLAB on macOS. It has been observed with R2019a, R2019b and R2020a Prerelease on High Sierra and Catalina macOS.
This can also be due to applications like Text Expander and Phase Express.
To work around the issue, please try one of the following solutions to see if it resolves the issue:
1) Switch MATLAB to use OpenJDK™ 8 (Hot Spot) version of JRE that can be downloaded from the following link:
To switch the JRE that MATLAB is using:
2) Switch MATLAB to use the JetBrains version of JRE that can be downloaded from the following link:
Installing the version of JRE linked above may cause JAVA errors in MATLAB. However, these errors should not have any side effects.
3) If you are using a multi-monitor setup, moving MATLAB to a secondary monitor may prevent the issue. However, moving MATLAB back to the primary monitor may cause the issue to recur.
4) Consider switching to Spectacle. Performance regressions have not been reported on this App thus far. Find more information on the Spectacle App in the link below:
5) You should be able to use keyboard shortcuts with no delays.
6) Closing the window-snapping app and restarting MATLAB may solve this issue. This has been seen to be effective for many past instances of similar behavior.
Alternately, you might also be able to work around this incompatibility by disabling some functionality in the window-snapping app you are using or changing its settings to ignore MATLAB.
For instance, we have seen that BetterTouchTool can be left running, but the "Window Snapping" feature must be disabled for MATLAB to function properly. If quitting the app resolved the issue, you may want to try to disable the "Window Snapping" feature and restart MATLAB, if it is more convenient for your workflow.

Same problem here, latest 2018 MBP, OSX 10.14, Matlab 2018b. Pretty much any interaction with GUIs - either the Matlab interface or custom GUI crashes Matlab. No window management software installed. It worked fine on OSX 10.13.
Update: As a matter of fact it does not crash, it is just extremely slow. On a custom built GUI it takes about a minute to change from one field to another.
Update #2: I run 2018a on my iMac with 10.14 with both BetterTouch and Magnet installed and there is no problem whatsoever. It seems that this is more likely a Matlab problem than a Magnet....

I know this problem, that's because I open a window-snapping apps which is a translation software. So just be sure that you don't open any window-snapping app.

I have a brand new iMac Pro, running a completely standard Catalina MacOS, and Matlab 2020 editing is often painfully slow. Relative to any previous Mac, it is very much slower, despite the much better hardware. It used to be said that Intel giveth and Microsoft taketh away. Now it seems that Apple giveth and The MathWorks taketh away. Currently, I'm mostly forced to edit on my freeware editor, due to extraordinarily slow Matlab editor.
Funny thing: Matlab is very expensive and freeware is, well, free.

Had an issue of whole program stopping when trying to use zooming features of scope in simulink with R2021b, using on M1 macbook air, but just by simply quitting rectangle (any window adjusting program) and restarting the matlab fixed the issue for me.
