My MacbookPro8,1 does not accept the Patcher!!!!

[fvbatistoni]

MacBook Pro (13-inch, Early 2011) MacBookPro8,1 SSD 128GB 2,3 GHz Intel Core i5 16 GB 1600 MHz DDR3 Intel HD Graphics 3000 512 MB C02F4H0EDH2G

I have tried to use Catalina Patcher but after install the system does not start. I had to format the SSD several times and go back to High Sierra. Unfortunelly I need some programs build to Catalina… Is there a way to fix this????

I have followed all steps in the site but does not work.

With CP I've had better luck (also on an 8,1) creating a USB and using that. Have you tried?
