Unable to update my computer

I have been trying for months now to download the updates for macOS Catalina, and it just never works. My MacBook does restart like it would do if I was doing the update, but it is only for some seconds and it opens again, and I'm still with macOS Catalina 10.15.3

The most common reason for this is that there is not enough space to expand the update and install.


How much free space on your drive?

Make sure you have more than 20GB at least, preferably a bit more.
