Chosen Solution
Hello, I have recently cleaned the hard drive on my imac and before I could ever get to reinstall Mac Os whenever I turn on the imac, a white screen pops up and I cant seem to remove it. Iv tried doing what I can and im stumped, I am not sure about the exact model of the Imac so i chose one that the photo looks similar too, iv tried holding command r, command r with option and all of those things but nothing seems to go to any screen but the white one. Any input would be great, i have a flash drive that i used TransMac to install a dmg of the MacOs but I dont exactly know how to use it and if I can when its in the white screen Thanks for any help.
Your hard drive is failing. To confirm boot up from an external USB drive with El Capitan or lower. Here’s the guide on replacing it: However if you do this without the OWC heat Sensor you will get run away fans. So you also need to install this: https://eshop.macsales.com/item/OWC/DIDI… iMac Intel 21.5" EMC 2389 Hard Drive Replacement
