I just downloaded MATLAB 2025a and no variables show up in the Workspace, even though they are actually saved in memory. For example, if I just open MATLAB and type x = 1, nothing happens. But when I type x, then MATLAB returns the value stored as 1. Nothing appears in the workspace, no named variables, variable types, the size or class, etc. If I right click on the Workspace and try to make a new variable, nothing happens. The "Save Workspace" and "Clear Workspace" are greyed out. Clicking "Refresh" also doesn't do anything. See the attached screenshot.

I have tried digging into the MATLAB preferences to see what I am missing, but can't find anything.

Note that I am running a 2024 MacBook Pro Sequoia 15.5.

I'm a little late to the party, but one thing to check is if you installed the Intel or Apple Silicon version of MATLAB. We've seen this pop up a few times for users who installed the Intel version on Apple Silicon Macs. This might explain why reinstalling fixed the issue for @Prieni.

I think mexect could be an easy way to check which version you have installed. If it returns mexmaci64 you are running the Intel version, so try installing the Apple Silicon version.

Maybe that is a correct fix. I had the issue yesterday, and I have the correct version installed (I am using a Mac with a Silicon chip):

However, for some reason, I closed and reopened Matlab today and now the objects are being shown in the workspace.

I think, if you can verify you have the right version installed, maybe you can go ahead and restart the laptop or something, rather than uninstalling and installing Matlab again that would be quite cumbersome (particularly given these type of issues usually arise after just having reinstalled the updated versions —e.g., the last version didn't open in Mac and we had to use a workaround too).
