MacBook Air A1466 (820-00165A) I’m so close to fixing it myself, I really want that sense of achievement; I’m fairly technical, but far from an actual electrical engineer! (I have the diagram/schematic to hand) Won’t power on, completely dead, except MagSafe light goes from green to orange...

Hi there guys! I'm wondering how i can dump the Mac Pro's LogicBoard/CPU-Tray SMC's as well. Is there a way to dump the content of both SMC chips, using smcflasher.efi from opencore shell or anything that can be able to do that? I mean from the 3 Mac Pro's 2009/2010/2012? The reason why i want...

I'm still using a Mac Pro 2009 as my main Mac. I bought a used Mac Pro 2009 for when it broke. The MP2009 that I bought was in a strange state. When I looked at the "About this Mac" section, this Mac is identified as a 2010 model. And the SMC version of the logic board was "1.39f11" and the...

My MacPro 5,1 appears to require frequent SMC reset to function properly. If I do not unplug and replug the MP before starting my daily work, I often notice that it become sluggish, programs load and run slowly and often hang requiring force quit. These problems don't appear if I reset the SMC...

Mid 2015 MacBook Air shuts down immediately after being unplugged. Tried replacing battery, and computer recognizes battery health as normal. Tried resetting SMC and PRAM. Resetting SMC solved it for maybe a day or so but back to it’s old ways. I was told it could be a logic board issue, but I...

I bumped an old thread related to this issue earlier today, but figured it prudent to make another to bring more attention to this problem while everyone is still within their holiday return periods. As you may or may not be aware, there's currently an issue that appears to affect all M1 Macs...

Hello, I'm wondering if there are some ways to hard wire or mod the logic board of a 13" Mid 2012 MacBook Air (820-3209) to boot from any custom made battery. Basically tricking the SMC to not validate the battery. I do not want to use SMC bypass since that will defeat the purpose and the...
