Hi, I tried installing high sierra on a 2014 macbook pro 13" but I canceled the installation at the point it asks to continue or go back, now Mac says it's installed and it won't let me install again or download it to install it manually. How can I remove the setting from the computer so I can install high sierra?
MacBook Pro with Retina display, OS X Mavericks (10.9.5)
I suspect that if you open the Applications folder and look inside for a file called "Install MacOS High Sierra" you'll find it. That's the installer. When you cancelled the installation the installation program wasn't deleted.
In addition to dwb, get rid of that, reset your NV/PRAM by pressing Cmd + Option + P + R prior to booting the computer, then continue to hold the keys as the machine boots. It will restart and chime - continue to hold until it chimes twice. Release the keys and then allow it to boot.
I would then download the installer again and attempt to reinstall.
