[QUOTE="nancykc, post: 1713685, member: 376442"] Hi, I found this on another forum and it seemed to work for a lot of users: "1. Go to About this mac under the apple in the upper left and click on More info 2. Click on system report 3. make a note of what it says after Model Identifier 4. go to your master drive – System -Library – Extensions – IOPlatformPluginFamily.kext -Contents – Plugins – ACPI_SMC_PlatformPlugin.kext – Contents – Resources – find the name from step 3 and move it to a folder that you can find again if needed. 3. Restart and you’re done" Probably inadvisable to mess with system files, but since it worked for so many others I tried it. Instead of MacbookAir6_2 I moved the MacbookPro6_2 file since the air one didn't exist. Upon restarting and doing an SMC and NVRAM reset (again probably inadvisable because now I don't know which change I made actually caused the results) kernel_task was back to normal CPU %, and the Activity Monitor looked normal. But the fan is still on high, the battery reads as 0%, and I can't seem to make battery level show on my toolbar (clicking the checkmark in system preferences yields nothing.) I will move my files to create more space. How much would you suggest...? [/QUOTE]
