pwede kang magdownload directly sa mac store/apps store or kng gusto mo ng temporary os lang para makagawa ka ng bootable meron sa torrent site then gawa ka osx bootable and install sa macbook after installing ang configuring you can download mac osx high sierra directly from the apps store and after mo madownload yan gawa ka bootable usb stick using terminal

press command space for quick finder search for disk utility
under disk utility select mo yong drive na gagamitin na bootable then click erase
