Hi Peter, I’m not receiving any WAMUG emails?? I checked the wamug archives and have copied & pasted my 1st reply I sent and your response to it below what I now suggest you try... if you are able to...
First, quit smcFanControl in the Menu Bar Then as the smcFanControl application is not in Applications but in Downloads, Delete the smcFanControl Folder in Downloads. Then, reset the SMC Reset the SMC The SMC (System Management Controller) stores crucial settings, a circuit that deals with Power management, temperature monitoring and Fan Control, status lights, keyboard backlights, and a few other components. If your SMC becomes confused, you could experience problems like excessive fan noise, slow performance even though Activity Monitor doesn’t show the CPU being overtaxed, apps take forever to launch, batteries that don’t charge correctly, problems with sleep or wake, and so on. If the battery is non-removable: 1. Choose Apple Menu > Shutdown 2. After your ac shuts down, Press Shift-Control-Option on the Left side of the built-in Keyboard, then Press the power button at the same time. Hold these keys and the Power Button for 10 seconds 3. Release all keys 4. Press the power button again to turn on your Mac. Regards, Ronni ================== Hi Ronni, after confirming the backup had completed and while I was out, my son took the Macbook to use and eventually it stopped again, black screen and fan whirring at full speed. I read your previous response and did that. A whole bunch of unintelligible (to me) DOS like information. I scanned over it and didn’t see anything I could interpret usefully. In any case it took me eventually to the login screen. My suspicion, following your previous email was that the issue was the SMC Fan Control third party app he had installed about 2 weeks back. So once I got in, I located it in the Downloads folder and Moved to Trash (I think the app was running from the Downlaods folder and not the Applications folder). Then upon emptying the Trash can - but not concluding that event, the screen went black. I still think it was that app that was the cause of all this. Now, the Safe Mode (or Safe/Verbose Mode) boot attempts do nothing but start the fan up and screen black. I’m leaving it for now as I am unsure what to do next.
