hi guys, 2 weeks ago i upgraded from mojave to catalina, i upgraded directly to 10.15.7 but right now i get an update in the control panel, which never ends. When I click on update, the computer restarts but does not enter any installation. somebody could help me?? is it a disk permission problem? because I don't get any units like "instal from" i have clover r5122
