I have MacBook Air 2017 , with latest update of Catalina OS , after updating the fan starts normal but when booting finished the fans goes at full speed,
Troubleshooting i did:
1- Air vents of the fan are clean
2- Run Activity Monitor; found most of the time (Kenerl_Task and Windoserver) taking more than 100% of the CPU.
3- Tried to restart / shutdown , problem remain the same
Please help
Thanks for the replay
Unfortunately "Paste.com" is not working here (I've tried to the change IP , using VPN , clear cache ..etc) still not working
However, I used hasten.com as alternative website, here is the URL of the ( https://hastebin.com/dihumuxeji.sql )
Looking forward for your replay , many thanks
You can save us asking dozens of questions by submitting a report from this App for us to look at…
EtreCheck is a FREE simple little diagnostic tool to display the important details of your system configuration and allow you to copy that information to the Clipboard. It is meant to be used with Apple Support Communities to help people help you with your Mac. It will not display any personal info.
Pastebin is a good place to paste the whole report if you capture the URL while there…
Whew, they've changed pastebin & made it harder, but after pasting in, click Create new paste button, then Embed button, then copy the URL...

Workable but harder for me to work with...the Note tool on the bottom of this editor's toolbar, as shown in the image, to copy and paste the output from EtreCheck. In a Reply before you click post, look for this to add longer texts...
Yes, I already did it and mentioned in the beginning of the discussion :
2- Run Activity Monitor; found most of the time (Kenerl_Task and Windoserver) taking more than 100% of the CPU.
And just to add : it takes long time during powering it up (Loading apple icon) to finish and move to password screen
Yeah, I was hoping we might get more info, Kenerl_Task runs everything.
To find out if it's system wide or user specific, try this...
Open System Preferences>Users & Groups, unlock the lock, click on the little plus icon, make a new admin account, log out & into the new account.
Does it work in the new account?
Well, I've just restart factory the Mac !
and the fan still running so fast , I've run Mac diagnostic dusting boot up, it's telling me the :
1- There may be an issue with the system management controller. Reference code: PFM006
2- There may be an issue with the power management system. Reference code: PPN001
I've tried rest the SMC (Before reseting to factory) many times , but didn't work
Runaway process - A process is using a large percentage of your CPU.
Open Activity Monitor in Utilities, sort on CPU%, see if anything using too much CPU%.
Fan runs fast and CPU at high usage
