I keep on getting the message that my computer clock appears to have been set back, but it is set correctly. Because of this, licenses for software I need to work with daily have become invalid. Why is this happening? Is this a bug in Mojave? How can I fix this?
iMac 21.5" 4K, macOS 10.14
Hello Andreas - Gothenburg,
Thanks for the post in Apple Support Communities. I understand you're seeing a message about your system clock.
The alert you showed looks to be from a third-party app; which app is that? Are you seeing similar alerts in other apps as well?
Which exact macOS Mojave version are you using under Apple menu () > About This Mac?
I understand you've made sure the time is set correctly; are you using a custom format? Also, do you have your date and time set to update automatically? I recommend checking out this resource to verify both: If the date or time is wrong on your Mac
If that doesn't clear things up, there are two tests you might try next that will help to narrow things down.
First, try booting your Mac into safe mode and test it out; this will help rule out some potential software causes: Use safe mode to isolate issues with your Mac. Once you test, click Apple menu () > Restart to get back to normal. Then, try these steps to create a temporary administrator account to see if you can replicate the issue there also: How to test an issue in another user account on your Mac
Feel free to reply back here with the results of the tests, and the community may be able to assist further.
Cheers!
Right I don't understand why you can't boot into Safe mode, have you tried the Terminal commands to see if the Mac will start in Safe Mode, see the link you were given earlier.
In your Date & Time preferences the Date Month Day display above the calendar is not in a usual format.
In mine you can see that is 17/05/2019 and in yours 2019-05-18, which is unusual and might be the problem with certificates not reading it correctly.
If you open your System Preferences> Language & Region> Advanced> Dates and switch the order in the various fields, perhaps you can click on Restore Defaults, if that button is live. Once you have reset the fields, Restart the Mac and then see if you can install without the certificate error appearing.
Hardly a Mojave problem, as not everyone is reporting it, open System Preferences> Users & Groups> Login Items
are there apps listed there that are due to open at start up. If so highlight them and remove them by clicking the minus button.
Restart the Mac and see if the problem occurs.
You may try resetting NVRAM and SMC, just in case.
Ok here is a post similar to yours from the Sibelius forum which you may want to read it includes the error message you were receiving and at the bottom of the page is a solution.

After changing to another region instead of Sweden:
Not my screen shot. 😎
FWIW, seeing your time & date is correct the error message not because of a problem with your date and time settings.
What app is giving you a problem?
I rolled back to High Sierra, and the problem is solved. Seems to be a Mojave problem after all.
Thanks. First problem is that I’m not able to get into safe mode, so I cannot test that option. I’ve read that lots of users seem to have this problem in mojave.
My clock settings are all correct.
Not it sure if this is a third party problem because I get this clock error screen also when trying to create a new account and even after having updated this morning to the latest Mojave update.
Anything else i could try? Or would rolling back to high Sierra the best solution so I can keep using my licensed software?
Thanks, I didn't notice that before. I made the changes so it looks like your screenshot in the advanced section, but the main date format doesn't change, even after restarting the computer. Is there another way to make this format change?
I am using Sibelius for music engraving, and it's deactivated now because it says the date is set back and therefor, my license isn't valid.
I have set the region to USA and now it is exactly the same as in the screenshot of the other poster, but that probably wasn't the real problem. I have also reset the nvram, still no luck. If nothing helps maybe a roll back to H Sierra is my only option, because I never had this problem before I installed Mojave.
I tried it many times, holding shift while starting/restarting, but it always goes into normal mode.
Here are the time settings:
Yes, that seems to be the only option left. I was able to restart in test mode but it didn't fix anything.
I would say so. That would have been my first option. I don't know which version of Sibelius is compatible with Mojave. That would be one thing Avid could tell you.
I doubt it otherwise this community would be alive with the same issue you reported.
Computer clock bug made software licence invalid. Help!
