hello. i don't know why are you telling me about the keyboard, that is bad. the batterys are new. indeed, I bought her yesterday just to be sure that the key combinations are ok. but doesn't work like I was expecting. now I verified the keyboard and is ok. I erased everything from Mac and installed Mojave, so there is the screen capture that you ask me for.

I’ve downloaded gpt disk rar, and extract from archive into a new folder, every file. So I have run gdisk64, under windows, but I cannot manage the app, because I don’t figure how is working....when I write something, I must press “Enter”....if I don’t press it, it return me nothing. When I press enter it will close the dos. Don’t know how it functions.

No, you are just missing a space between 'gdisk64.exe' and '0:' . 😉


0 identifies disk0, 1 identifies disk1, and so on....


On the macOS side, it is a bit easier.


sudo gdisk /dev/disk0
