ntpdata: command not found .. macOS Sierra
Hello everyone ..
a cubles days ago I tried to install another OS on my MacBook Pro 2015 and when I reached a point to choose where to install the system I formatted all the Partitions there even the one that contained MacOS Sierra after that I realised that I made a huge mistake I tried to restart the mac .. There is NO OS to boot and when I tried to install the macOS again there was a message popup after a few mins from the installation process that said: "An error occurred while preparing the installation. Try Running this application again"
I tried many times but it didn't work at all .. I look for a solution and then I figure out that when I start to give the system a command on Terminal "date" or "ntpdate -u time.apple.com" give me the same massage command not found .. even when I try to change the date using this order: "data 1030010224" I get the same massage.
so Please I want some help to Reinstall the MacOS system ??
