It’s been a while since I’ve posted and I’m definitely going to get back to from today on. My first post since March this year and I’ve found a resolution to my Macbook Pro being pegged around 40 to 70 percent CPU usage. It’s this process called secd, supposedly it’s for security and there’s a solution to make it stop going nuts.
This method will likely only take effect if you don’t use iCloud or don’t have it enabled. There are a couple more options out there to get this to stop happening, but this seems to be the most popular. The first thing you have to do is go to iCloud preferences in the preferences panel. Then login to iCloud. Then you click on the keychain checkbox and it will ask for your password again. Put that in and save.
That’s it. The process secd will go back down to some 1 or 2 percent of CPU usage and your computer will return to normal. You can even log back out of iCloud and uncheck keychain if you want to go back to the way you had your computer. For some reason there seems to be a bug there and Apple coded it to loop a billion times or something for syncing to iCloud without checking to see if you’re even logged in. Oh well. Hopefully that helps somebody out there.
