how to download 10.15.7 full installer?
I need the full installer download for macOS 10.15.7 so that I can make a bootable USB installer from it.
I am running macOS 10.13.6 on a 2017 iMac and do not want to actually install 10.15.7 at this moment.
When I download 10.15.7 installer from Mac App Store, all I get is the 19 MB mini installer instead of the 8 GB full installer that I need.
I do not want to get the full installer via some third party app.
Please assist.
iMac 27″ 5K, macOS 10.13
