how to upgrade cpu on late 2013 imac 27in

Restarting no matter what takes me back to the installer and it always fails. I tried making sure it was connected to the internet, I tried a bootable installer drive, and no difference.

I get the error at this point every time. I also have automatic updates turned off.Īfter hours of trying to figure that one out, I finally realized that Apple forced this download on me at some point apparently and even though it was never installed, the installer was in my applications folder making the App Store think it was already installed? How stupid is this? Did Apple not even think about how confusing this would be to forcefully make users download the new iOS without noticing? My internet is rural as well and at some point this 5+ GB download occurred? Ugh, okay so after realizing this, I ran the installer from the applications folder.Īfter about 20 mins or so (it says 37min remaining) I get an error that OS X can't update and no further explanation. It also says I'm on an older version in the about this Mac section. I'll first start with the fact that my mac says in the App Store that high sierra is already installed, even though I never downloaded any apps with this computer let alone installed them. I am a web developer and I have never been so frustrated with tech in my life. I have spent the entire weekend now trying to update my 27' 2013 Imac to high sierra, I am on whatever OS came with the computer.
