Hi, everyone!
Some time ago I sucessfully installed High Sierra on my laptop (Lenovo Y700 15 ISK, Intel i6700HQ, HD530).
Now I'd like to upgrade to 10.15.5 (Catalina).
I followed all instructions as before and created bootable USB (I used previous files: kexts, *.aml and config.plist from High Sierra installation times).
I expected, that something may go wrong. But I was really astonished, when I saw this error:
I have been trying to search this error. All recommendations, which I could detect were about setting RebuildAppleMemoryMap to OFF and SetupVirtualMap to ON. I couldn't find these properties in my config.plist. So I was searching similar configurations with these properties. But no one of these configurations couldn't help me with this problem. Every time, when I'm trying to run installation process I see this error. (BTW I'm still able to work on installed High Sierra). To be honest I don't have any ideas what to do. So I would be highly appreciate anyone who could help me or give any suggestion what should I try.
Thanks in advance!
