Cura 4.8.0 beta does not run on MacOS Big Sur 11.0.1.beta

I run MacOS Big Sur 11.0.1.beta on MacBook Air and the beta version 4.8.0 does not start up. 4.8.0 runs fine on previous OSX version like Catalina and High Sierra.

I think this is a known issue.  Something about the installer and security.  I think the older versions of Cura (before 4.7 I think) work on any version of the Mac but the newest versions (starting around 4.7 or 4.7.1) need the latest Mac operating system because they are... signed?  Something like that?  I'm not a Mac person.  But if you google around on this forum there is discussion.

I have the same problem on a Mac Pro running Big Sur. Under Catalina there was no problem.

I just updated two Macs to Big Sur and Cura 4.8 final is running fine. So it seems it was fixed in the final version.
