trustd CPU usage

Activity Monitor shows that ‘trustd’ is using up a large amount of my CPU and it has made my Early 2011 MacBook Pro insanely slow. Spotlight doesn’t appear to be indexing anymore. Anyone have any idea about what it’s doing?

Same here - iMac 27" 5K - trustd is using 100% - sometimes there are 2 instances and yes it makes the system run very slowly

i think i will wait until the next update because my MacBook is too frustratingly slow to use

Try deleting or renaming your login.keychain. I had the same problem after upgrading a 2015 MacBook Pro to Sierra and it seems to have done the trick.

Hello, how can I rename the login.keychain and where do I find it?

Thanks in advance

it happens to me in high Sierra more than 100 percent of cpu during almost 2 minutes then it down
