My 2017 MacBook Air began having a problem with a high kernel task and high CPU with fans blaring. I did a hardware test and it said there may be an issue with the SMC PFM006, there may be an issue with the power management system PPN001.
After reading online that it may be to do with the track pad's thermal sensor I took the Mac apart and disconnected then reconnected the track pad. I and also cleared the dust of the machine. I did the hardware test again and it was all clear. So I began downloading all the software that I deleted while troubleshooting and during the downloads the problem came back.
It's giving out the same hardware errors again, however now the system seems to run a little smoother, but the fans are still blaring. Any advice?
