thanks for your comment.
I am starting from scratch, I have manage to get an original Mac to create the usb install disk directly in Mac (avoiding Windows)
But I am still stuck on the process.
clarification, my laptop is Lenovo G50-70 (at least this is printed on the back). Is this tutorial still valid?
1st try: I have created install usb with Unibeast. Tryin to install Mac on laptop, Apple logo is displayed and progress bar was moving very very slow. At the end of the Progress bar, it was stuck some time until I was tired to wait.
Note: I was waitin one hour after the progress bar reach the end. ;(
2nd try: I have copied in efi partition two files mentioned in the tutorial and attached in post. (Config.plist, and SSDT-EC.xml).
With this approach, clover started, but I Don’t see the install Mac Catalina drive.
I will repeat the process today. I’d there is any suggestion, it will be welcome.
