i'm having a boring problem on my Macbook Pro (2016), with macOS Catalina and Matlab 2019a.
I have a figure that i have to modify some style stuffs, and I would like to use the property inspector and get then automatic code for other figures. However, as attached in the screenshot, the property inspector remains blank. Did anyone get this problem and solve it?

I have the same issue. This is not the only problem. Windows (only Matlab windows) do not show up under mission contorl in MacOS Catalina either.

I have the same issue with Matlab 2019b. Is there any workaround yet?
And in the mean time, how can we change figure properties in mac?

Please do not post answers if you're not answering the problem. As per the link I posted, this is a known issue with no workaround.

I had this problem too.
However today, after receiving and installing the R2019b update4 (v9.7.0.1296695), the problem has been fixed. Property inspector shows normally now on my Catalina. And the problem of MATLAB window disppear in mission control seem to be also fixed (most occassion, also disppear when property inspector is on).
So try to update R2019b update4. That update message can be found on the right top of MATLAB window, the bell button next to 'sign in'.

i had the same problem, macbook pro 16" Catalina 10.15.3, Matlab 2019b.
However, as X.Z. Tan suggested, I checked for the update 4.0 and the property windows appears again.
Thank you a lot.

I updated today to MATLAB Version: (R2019b) Update 4. Unfortunately, the property editor still does not open. I am hoping that MathWorks is aware of, and working on, this problem.
MacOS Catalina 10.15.3 19D76
MBPro 15 late 2018

Glad that update works on Christian's MBP.
For Mark' comments, I don't konw what happened. I have exactly same macOS, Matlab version and MBP15. Maybe try to reinstall the Matlab R2019b.
However, Matlab can work on my MBP, I still feel it response slow and not fluent. It still need more optimization on mac.

This is a known issue with no workaround currently. See this answer by Mathworks.
