My Matlab R2019b runs extremely slow on my Macbook MacOS 10.14.16

This is the set-up of my macbook

It takes more than ten minute to start my matlab and there always a "processing" circle running and making my CPU runs to 95 degrees. And a slight modification to my script, such as changing a number without running it also take 1-3 minutes "processing"

When I try to open my Add-ons, this shows up. I'm not sure if this has something to do with the slow-processing.

I am not a software engineer but a sport scientist, only have limited knowledge about software engineering. Can anyone help me with this?

I have the same problem, too.

Answer 1

[Steven Lord]

Are you using the Magnet app or something similar? If so try turning Magnet off.

[Sirius Huang]

Nope.

[Michael Black]

Wow, that worked for me! You can let Magnet just ignore the Matlab application, if you want to keep Magnet working on other windows. Thanks Steven!

[Tara Ghafari]

It helped! thank you very much. I would have never thought of Magnet as a cause of slowness.

[ZETAO YANG]

Thanks a lot!!!

[Gary Bikini]

Magnet is the reason! You saved my life. Thank you, Steven!

[Samuel Gallagher]

Thanks Steven, this also worked for me!

Answer 2

I found this solution in another thread, and it makes the "Processing" circle go away:

disable source control integration. a. On the Home tab, in the Environment section, click Preferences. b. In the Preferences dialog box, in the MATLAB > General > Source Control pane, select None.

This fixed my problem!! Thank you so much
