Why wont matlab start up on my laptop?

I am unable to start up MatLab on my laptop. I was running it succesfully all last fall, but now when I try to start the program it "flashes on" as though its going to start but then immediately closes. Do I need some kind of renewal or update?

I have the same problem sometimes. On my computer this is caused by a wrong target location of my desktop shortcut. The shortcut thinks my matlab folder is saved on my C disk but it is on my D disk. Is this also your problem?

Maybe. But Im using a MAC so I don't have a C or D disk. I'm not sure how that translates?

Are you using Catalina? Catalina is known to have startup problems. Some people are able to start it from the binary with the -nodesktop option.

If you are using Catalina and have any accessibility services enabled including Magnet or Default Folder X, then try disabling those

I am using Catalina, darnit. I looked into accessibility and dont see the services you name "Magnet" or "Default Folder X" but as far as I can tell none of the accessibility services are enabled. How do I access the "binary?"

Or could I down load a newer version of MatLab? I am using 2018 b but have access to 2019 b.

I think when I launched MatLab for the first time after installing Catalina, it asked for "access to ... " something or other which I denied. Was this the problem? How can I get back to that prompt?

R2019b is the first supported release for Catalina, but has problems
