Beta 1 installed OK. when I install the profile and install beta 2 appears after a few mins of the install running. Any idea why this is occuring ?

Same here.

I also experienced this with Beta 2, installed over Beta 1, on my 2018 Mac Mini. I had also gotten a "failed to verify..." dialog on the download. However, after "rinsing and repeating", the installation is now proceeding normally.

I had the error as well but it was gone after a reboot.

same here, late 2015 27 inch 5k imac with Catalina beta 1

I posted in the adjacent thread the solution that worked for me
