Hi there,

I can't synchronize iCloud data, because I don't remember passwords of old macbooks, how I can remove old macbook's data from iCloud ?

when I press Resume Data Sync, it asked password of current macbook and passwords from previous macbooks, but I don't remember them

passwords did Not migrate to new MacBook Pro Just replaced a nearly ancient MacBook Pro with a new 16 inch version of same. My passwords did not migrate with other data. I'm now creating new passwords in the new computer and saving to a file in iCloud. It'll take forever to do this with all my accounts. I've gone back through everything and enabled passwords sync as well as yes or sync on everything I can find in settings. Obviously I'm missing something. Running 14.1.1 on this new device and the old laptop from 2018 has 10.14.6. My gratitude to anyone who can tell me what I'm missing. Thank you, Louie

iCloud Passwords and Keychain Sync this Mac toggle won't turn on since updating to Tahoe Just updated to Tahoe 26.0.1 from Sequoia today and now the iCloud Passwords and Keychain "Sync this Mac" toggle won't turn on in iCloud Settings. Also get the notice "Some iCloud Data Isn't Syncing" but clicking "Resume Data Sync" toggle doesn't do anything. Currently the Save to iCloud setting for Passwords is off, but Photos, Drive, Notes, Messages are all on and working. I'm on a Studio Mac M1 Max I've tried logging out of my apple account on all of my devices turned them all off. I restarted Mac first as suggested in some forums as it should have the most up to date passwords. Still didn't work after logging back in. All my other devices (ipad, iphone, Macbook Pro) are working fine and I'm able to toggle the Sync this phone/mac button on all of them. I logged into another user on my Mac Studio and it worked without a problem, using my same apple account, so this seems user specific on my Mac Studio since the update. Any help would be appreciated. I use the Studio Mac the most for changing passwords and it should have the most up to date passwords so I'm reticent to completely reset my passwords on it, but if that's the next step, I'd appreciate the step by step so I don't lose any information.
