However for now, i went again through hish sierra. cant see other options for downloading earlier versions of os like lion, elcaptain. (which i dont wish to / i dint find any option to roll back into lion os or the earlier os that came along at the time of purchase.)and then again as per the instruction by Apple care service centre for /internet recovery clean install,i did Control +R, then disk utility > erase all data from macintosh HD.then > recovery Mac os.
Clean reinstall mac os sierra mac os#
I followed the instructions as suggested by apple service centre(telephone).Command + R to getting into recovery modei then tried to reinstall MAc os from disk utility in boot.-> it then took me to the page install high sierra. and mic dont respond sometimes.so then i though to roll back/downgrade to el captain. and other hardware problems are like camera hardware is not discovered on this OS HS.

(dont have any backup or time machine- complete erase all data and installed mac os hs).It's clean and complete os without any any installation problems.after a two days of usage i found my mac is working very slow, sometimes stuck on loading os. i did clean install successfully without any errors.
