Experiencing errors with my Mac OS clock after Sequoia 15.0.1

BTW, the Terminal NTP command did not solve my problem. For the following several days, my clock was out of sync. My computer upgraded to 15.2 though and that for me solved the issue, my clock is now properly in sync for several days.

It seems that for some people, 15.2 broke clock sync, but for me it fixed it...

I am running Sequoia 15.0.1 and have been experiencing errors with my Mac OS clock for months. Strangely the clock seems to be running slow, losing about 30 mins every 6 hours, like an analog clock. I have tried turning on and off Auto Time and Date setting, same with the Auto Time Zone setting. The system clock ends up being wrong with these toggles turned on or off. Manually setting location and time leads to the wrong time and date.

I have tried running Terminal commands that have been suggested by various people e.g. sudo rm /var/db/timed/com.apple.timed.plist

Not sure what else I can do!

You can re-sync to Apples time server from Terminal.app copy and paste:

sudo sntp -sS time.apple.com

(Please note: your psswd will not echo, type it in anyway, to proceed use the enter/return key)

Sonoma had some bug introduced early on that was sorted with point update.

Have not heard an issue with Sequoia here...

You can Set the preferences manually, no harm there—the option is toggle OFF "Automatically." I would do what works.

or from the Terminal.app copy & paste:

sudo rm /var/db/timed/com.apple.timed.plist

verify your software is up to date…

The current stable release of Sequoia including bug fixes, security updates is macOS 15.1

After running this Terminal command, you need to reboot your Mac. Also, consider upgrading to macOS Sequoia 15.1.

Have you tried to update to macOS Sequoia 15.1?

See if this helps...

Without any connection to the internet, the Mac has no way to get the correct time automatically. Without a connection, you would have to set the time manually (from a reliable source) but it would drift eventually.

You would have to set up a local time server, then have all the Macs connect to its address in System Settings > Date & Time > Source. No, I don't know how to create a local time server.

I have also experienced this problems on Sequoia 15.0 - very annoying actually. Normally when I open my computer, then the clock is the same as when I closed the computer. I'm considering updating to see if the problem persists.

I starting having this *after* upgrading to 15.1.1.

I just tried the terminal command above, I'll see in a few hours if it works.

One of my many grievances of the upgrade to Sequoia (including my canon printer first not being supported in 15.0.1, and then recently allowing me to install but not working properly, and the endless "give permisssion to xyz app to access folders", which caused my jupyter notebook server to not see my documents folder, but then it did after a illogical sequence of commands...). This will probably get edited out of the support forum, apple does not seem to like people expressing discontent on the forums...

That could be because this is a support forum, not a soapbox.

I am experiencing this issue as well. Issue started after updating to Sequoia 15.2

Running on a

2019 MacBook Pro 16 Inch

Model Identifier: MacBookPro16,1

Processor Name: 6-Core Intel Core i7

Processor Speed: 2.6 GHz

Please find the bug and fix the issue!

Clock sync is achieved by your computer updating it's time based on a reference server. If you have no network connection at all, you cannot sync clocks.

If you have two machines on a private network with no internet connectivity, you could set up your own NTP server, assuming it had a trustworthy clock (ie. via GPS).

If you want to buy some extra hardware and install some software yourself, you can theoretically sync your macbook itself to a GPS signal:

Having the same problem, it also continued after updating to 15.2 and it appears to be occurring even more often now. It messes up your calendar etc. so it would be nice to see this fixed.

I wonder whether permanently using VPN may affect the automatic clock. Restarting the computer or changing the time setting from automatic to manual and back again, does give you the correct time, but it's a temporary fix. Close your Macbook for a while and time will have stopped again.
