20 Mac Os Helpers in West Melbourne

Re instal mac os on desktop with out damaging data I tried deleating mal ware and.the running program shut down

My iMac has been formatted completely and I am trying to install High sierra on it. However, I have no other option but to install el capitan, for which I tried 2 options without success 1) From the apple store using internet. isnt working because this version doesnt exist anymore 2) Startup disk, I am not able to download the version from mac store on my other macbook because its on a higher version. Download from torrent isnt compatible So looking for someone who can get this done

With the later version of the Mac OS, the Overscan/Overscan slider has been removed, causing the outer edge of the display to be cut off. It means the dock and the menu bar are out of frame and you cannot see them. Adjusting resolution renders the picture of very low quality and useless for my purposes. I've read there's a fix but I only use Mac for music and my technical expertise is in PC. I need someone who is familiar with this problem to fix it.

My mac seems to have corrupted and needs to be reinstAlled after taking backup of data. Need someone to restore the data and reinstall the os
