MAC OS Catalina Crashes Every Day: "Accountsd wants to use the login keychain" "this mac can't connect to icloud because of a problem with"

If your Mac keeps asking for your keychain password

Your keychain may be locked automatically if your computer has been inactive for a period of time or your user password and keychain password are out of sync.You can set a length of time that Keychain Access waits before automatically requiring you to enter your password again.

1. In the Keychain Access app  on your Mac, click “login” in the Keychains list.
2. Choose Edit > Change Settings for Keychain “login.”
3. Select the “Lock after” checkbox, then enter a number of minutes.
4. If you want to require a password each time the computer goes to sleep, select the “Lock when sleeping” checkbox.
5. Click Save.

Wow, sounds like you’ve got a lot going on! Possibly a Keychain issue, but also with some third party software, and maybe Gatekeeper as well.

If you start in safe mode does it make a difference?:

As Kappy said if there’s an issue with the local or iCloud Keychain, sometimes it may need to be reset it other methods done work:

Open Keychain Access from Finder > Applications > Utilities.

On the top menu select Keychain Access > Preferences > Reset Default Keychain, and enter the password of your current admin/user account if asked/restart.

Otherwise you’d have to reset it manually, (Note that either way this will erase the stores passwords on your Mac and/or iCloud, so recommend backing up with Time Machine and also disabling iCloud Keychain in System Preferences before hand.

If you’re still having troubles, can you check the Date and Time preferences in System Preferences, just to make sure those, as well as the time zone is set correctly? This might also cause similar issues.

Hey again! I’d say if you did a clean install WITHOUT migrating the data, setting it up as new, creating a user and then enabling iCloud Keychain wouldn’t cause a problem at all, you might just have to enter your old Mac password when signing into iCloud that’s all, (The new one can be the same or something totally different, doesn’t matter).

And for sure I’d install any applications carefully just making sure one isn’t causing a problem before installing the next one. Most of the time a clean install will fix any issue, (Unless it’s a hardware issue, or third party conflicts installed), especially if the problem is just re-migrated back onto the new Mac.

Id even make sure to test it after the clean instal to make sure the Mac is working just fine with no data, you can even skip the Apple ID sign in and do that later, but that’s probably unnecessary if setting it up as new.

You can always run hardware diagnostics yourself though to be sure, just start up holding “D” on the keyboard:

This is a pretty good way to rule out hardware....anyhow good luck! (Resetting the NVRAM is a good, simple, non-invasive step to take as well, like you said earlier for sure worth a try considering some of the symptoms.

I got a new MBP yesterday and ran the migration assistant from my previous MBP. This exact same thing has happened twice to me in the last day. I first saw it occur when coming back to my desk in the morning and unlocking the screensaver. The first oddity was that my finger print wouldn't work. Then entering my password took awhile, i'd type a bit and it would pause. Eventually once I was past the login screen I was presented with most of my applications closed but numerous instances of the icons on the dock. Accountsd wants to use the login keychain message was present that cycled through a few other things asking for access as well. This kept going awhile and eventually everything just stopped responding. Holding the power button down to force a shutdown was the only solution.

One thing I did notice, the wifi symbol was showing it not connected to my network. I've been searching all night for other examples of this happening and your description is nearly exact for what I have been experiencing.

It's pretty frustrating to not be able to leave my MBP on with my apps and documents open only to have to force shutdown in order for it to work :/

I'm not a computer expert...but my impression is that this is some kind of MALWARE. I'm speaking of that window that starts out "accountsd". I say that because:

1) "accountsd"? sounds fishy

2) selecting "OK" simply causes the window to "shake" (as in...I need an input)

3) selecting "cancel" causes the window to immediately reappear

4) the "help icon" on that window produces no results.

I called apple support. The gent seemed aware of at least the generic issue. Here's what he had me do:

FINDER/GO/LIBRARIES: send all to trash

/CACHE: send all to trash

/LAUNCH AGENTS/SAVED APP STATE: send all to trash

/APPLICATIONS/APPLICATION SUPPORT: he looked thru them all, saw several he said are "known problems", I didn't write down the full name but it included "Advanced Mac cleaner", "AMC", MacKeeper ..."

DON'T Empty trash yet.

SHUTDOWN....on restart, then empty trash.

He also suggested a good malware app: "Malwarebytes"...suggested I try the FREE DOWNLOAD and see what I think.

FYI - installed 10.15.6 Supplemental Update and it's running well for 4 days

I've the exact same problem since upgrading to 10.15.6

Clean install helped for couple days, and then the problem re-occur.
