Any ideas on what might be causing my iMac to run slow and fan to be running fast after replacing the display. The display works fine and when I put the old one back in, the iMac runs normally.
Sounds like you forgot to reconnect one of the sensors or damaged it. Install this app so you can see what sensor is failing: TG Pro. Paste a screenshot of the console window into your question so we can see.
Hi, is there a way to trick the iMac to “think” it is connected with the LCD? I am thinking to use the hardware without the display panel. However, my iMac is very slow and the fan is at this full speed when the display panel is not there. Thank you !
