Hey everyone, Unfortunately there was a liquid spill on my 2013 MacBook Air. I shut it off, disassembled it and cleaned it out and dried it. I reassembled it and tested each of the hardware features (camera, speakers, mic, usb, etc) and to my surprise everything works fine. It wasn't until after I used it for a few hours that I noticed it was shockingly slow. I investigated it and found kernel_task to be eating 300% CPU. After a little googling I was lead to threads on here and other mac forums with people who have had similar issues. Apparently the computer believes it's hot and is eating up CPU with low cost tasks in an attempt to throttle applications it believes are heating up the computer. I installed HWMonitor, and sure enough Heatpipe 2 sensor is showing 128 Degrees Celsius. Also, the Apple Diagnostics reports PFM006 which I believe is the SMC. I've looked over the board again and gave it an extra hard look for corrosion and I can't spot anything I can clean further. If I can't fix it on a hardware level I'd be satisfied with a software level solution. It just seems a shame to discard this expensive computer because of CPU usage. The problem seems solvable. I found this which sounds great: http://www.rdoxenham.com/?p=259 As well as many other people who used the fix successfully. I'm running Mac OS X 10.9.5 and it's a MacBookAir6,2. Unfortunately under /System/Library/Extensions/IOPlatformPluginFamily.kext/Contents/PlugIns/ACPI_SMC_PlatformPlugin.kext/Contents/Resources there is no MacBookAir6_2.plist. I decided to move all the files out of there but it didn't help. I also found this: http://tech.superhappykittymeow.com/?p=258 But unfortunately I don't have either of those available when I look. Can anyone shed some light on why I can't apply these fixes? Has something changed in the macbook air 6,2 model that prevents these fixes from working? Or is it because I'm using OS X 10.9.5 ?
