I am unable to upgrade my MBP (2017) with Mojave 10.14.6 to Catalina (10.15)
What is the software update tool checking for, so that it knows whether an update is available or not? The menu item under the apple icon (top left) says I have a software update, and when I click on it, the system preferences panel runs a check and says there is not update and that I have the latest software 10.14.6 on my system.
I know others are facing this situation. I cannot do a complete reinstall. That SHOULD not be the right answer for this. I have a lot of data, a bunch development applications and configurations and customizations that I don't want to have to recreate.
Can you help me upgrade to Catalina from 10.14.6?
