After installing the required upgrade with High Sierra, the machine starts to boot up with a chime, then the screen goes all white. Tried safe mode using Command/P/R but that does not work either. Any suggestions?
iMac 27″, macOS 10.15
I think I posted a reply that was intended for another topic in this topic. See if this Apple document is of any help: If your Mac doesn't start up all the way
In any event you have an 18 year old Mac and it is considered obsolete by Apple. That means that Apple won't work on it but maybe an Authorized Apple Service Provider will. However, it won't be inexpensive and parts may be very difficult to find. You would be best served by putting your money into a new iMac.

What year and model iMac is it?
Also do you have the "Start ups automatically after a power failure" check box selected in the System/Energy Saver preference pane?
