Screen lock & fingerprint unlock are very slow in macOS 14.6

Hi, I'm using MBP M1 Pro. After upgrading to macOS Sonoma 14.6, I'm experiencing slowness in following scenarios:


-Locking the screen: either by pressing the power button shortly, or by going to Apple icon and selecting "Lock Screen" - the screen turns into the wallpaper almost immediately, but the date, time and account icon do not come up, sometimes for even 20 seconds. Until they do, touching fingerprint scanner, or typing the password, does not unlock the MacBook.


-Unlocking the screen: Once the date, time, and account name are visible on the screen, I'm able to unlock my MBP either by typing the password or using the fingerprint scanner, but the fingerprint unlock option can take up to 10 seconds (with the loading "circling dots" animation at the bottom of the screen) to unlock it.


I have tried booting in Safe Mode, but my experience with locking & unlocking was similar there.

MacBook Pro 14″, macOS 14.6

This fixed it for me:


sudo dscl . deletepl /Users/<accountName> accountPolicyData history


(Replace <accountName> with your own account name.)


Apparently the longer the history of account policy data, the longer (un)locking takes. In my case the list was huge because of repeated policy updates.


Running the command above resolved my issue instantly.

In this Specific User's case, the real issue that the computer has Profiles Installed which in turn tends to indicate the Computer is a Managed Computer and is enrolled in A Mobile Digital Management Service

That in and of itself would point elsewhere and not some much to the UpGrade of Sonoma 14.6

I disagree. My computer has been managed by my IT department for almost 3 years now, and the locking/unlocking was always smooth.

Then, right after I updated to Sonoma 14.6, I started to experience this slowness.


So I agree that it might be connected to Profiles implemented by MDM service, it has definitely been caused by 14.6 upgrade.

Afternoon all,


We've been experiencing the same issue on Intune managed devices running macOS 14.6.1.


I was able to verify that going back to 14.5 resolved the issue. After the device upgraded to 14.6.1 again the issue re-appeared.


I reported it to Microsoft and they asked me to try removing the MDM profiles and see if that resolved it.


Again, I can confirm that unassigning all of the configuration profiles, scripts and apps resolved the issue. The primary Intune management profiles remained since the device is still linked but this is good.


However, I was determined to find the specific cause. The previous comment about the issue not being present when a different user logged in led me to check the configuration profiles that are deployed via the user channel vs. device.


After re-applying all of the configuration profiles and scripts one at a time I was able to track the cause to a single profile in Intune that uses a Custom Configuration profile to set the local device password policy. It uses the com.apple.mobiledevice.passwordpolicy payload type.


Removing this policy by itself resolved the issue after a restart and re-applying it made the issue return.


I can't guarantee it will resolve the issue for all of you since your setup may be vastly different, but it's worth checking. Failing this, removing your user deployed profiles may help you narrow the cause.


The user related profiles can be identified by going to System Settings > Privacy & Security > Profiles.


At the top there should be a section named User (Managed).


I've passed this info and the configuration profile XML file onto Microsoft for review.


Thanks and good luck!

I can provide hard imperial evidence it's not specifically to do with MDM profiles... we removed enrollment from one of our systems, and the problem persisted. Even after Active Directory configurations and Kerberos SSO configurations were pulled.


We cannot simply defer to the "well just nuke it" solution and expect that to solve our problems. People have jobs. People are devoted to the projects they're working on, and when a macOS update comes along, the answer cannot simply be "just give them a new computer / just erase their computer and start over". That is not knowing your user, and that is not a viable option. You've not taken the time to troubleshoot or show ownership of the problem.


So to add something of value to this thread...

  1. I know that removing Directory services configurations does not make the problem go away for a user's account
  2. I know that removing MDM profiles (fully unenrolling a mac) does not make the problem go away for a user's account.
  3. I know that we can sign into another local account on the system, and that account seems to be fine with locking / unlocking.
  4. I know that clearing ~/Library/Caches didn't help my particular user.
  5. I know that the problem persists for my user on macOS 14.6 and 14.6.1.


So I'm going to theorize that there's some kind of preference or cache sitting somewhere holding onto stale data and it's causing the authentication process to stall.

Hi all,

we experience the same issue. Login takes quite some time until processed.

Not on all machines, but some.

The only common thing is the OS though, so macOS 14.6 or 14.6.1.


I manage macOS devices in Intune, Jamf (on-prem and cloud) and VMware. On all three MDM some machines show the same behavior after the update to 14.6.x... So to me it seems that it is not a MDM issue. Since these three different vendors probably do not make the exact same updates on the exact same time. And, to my knowledge, all MDM use Apples API/APNS to work their MDM magic anyways. So not much they can do without Apple altogether.


To take updates into our own hands is another fun thing with macOS. Apple does not allow postponing updates for longer than 90 days. So no big help there. (There are ways to block updates altogether, of course. But that would probably be worse than just living with these few users and devices that experience this issue currently).


So pretty sure we have to wait for a fix from Apple here

I have exactly the same issue. Since few days (after upgrade to 14.6) if I lock the screen it shows the wallpaper and it takes 6 seconds to show the user icon (so you can unlock again). When you try to unlock (touchid or password) it takes another few seconds before the screen actually unlocks. TouchID works fine as you can press it for a fraction of second and few seconds later the screen gets unlocked.


I have my MBP 14 Pro managed by MDM profile. The moment I remove the profile ... everything starts to work fine again, so it is somehow related to upgrade to 14.6 and having your MBP managed by MDM profile.


At first I thought my company is at fault (new security policy or sth), but reading so many other people having the same issue I tend to think it is Apple's fault ... clearly a bug in macOS 14.6.


What is interesting, after I apply the MDM profile again everything is almost ok (it shows the user icon fast, but unlock is still slow at occasions) ... until the next restart.

So for now my solution is to not restart or after restart: offboard and onboard MDM profile again (and to not restart).


Aug 9, 2024 11:05 AM in response to Creyden

This is happening to various companies across different MDM platforms. This is NOT the fault of the MDM but rather a change that Apple needs to address. I just want to know that this issue has been made aware to the correct team so that we can apply security updates to our company machines and know that this issue will be addressed.

How many times has the computer been Restated since the Monday July 29, 2024 Sonoma 14.6 update was released ?


Or >>


Restart in Safe Mode. This will perform a Disk Repair, clear cache files and only load Apple Software, extensions and fonts.


The boot up will be slow and can take some time - Normal.


Safe Mode will also eliminate Third Party Software, extensions and drivers from loading.


It will only load the Minimum amount of Core Apple Processes to allow the the computer to function at a reduced Level of Performance 


Does the issue present in this mode ?


Sometimes a Safe Boot followed by a Normal Boot will just put things right.

Yes, as I wrote earlier, I have tried booting in Safe Mode and experienced the same slowness.

This issue seems to be variant from another similar, not the same in all respects
