I downloaded the binary sage-9.2-OSX_10.15.7_x86_64.app.dmg in order to install SageMath 9.2 as an app on my Mac running macOS 10.15.7. I already have SageMath 8.0 as an app, which I installed with no problem some time ago, but since I don't know of a better way to upgrade I am just trying to install the SageMath 9.2 app.
The download works fine and when I open the dmg and drag the app to 'Applications' the app starts copying just fine, but after a few minutes I get an error message saying 'The operation can't be completed because you don't have permission to access "SageMath-9.2".' and the process stops.
Incomprehensibly I cannot include the images (nor their links) because of karma but you can access them here (changing [dot] for a ".") if you'd like to see what happens:

Do you have any suggestions as to why this might be happening and how to solve it?
Thank you very much!
