Update to 10.12.4 causing Date/Time Issues

I'm running a bare MacBook Pro 2014 model. No dongles or VPNs or Abel kin devices. The first time I saw the 2040 date was before the update. Still a mystery for me. Apple is taking a look at my logic board. I'll keep you posted.

I had this same problem 2 times in 2 weeks on a brand new MBP .... First time I wiped the HD and reinstalled Sierra from scratch. Second time I managed to figure out how to revive the MBP. This bug is very annoying !

I'm having the same issue. I haven't been using any external peripherals. Upgraded to 10.12.4 and twice now I've booted with the system date set to a day in 2040. Manually set date and time, turn back on automatic date and its fine. However the real annoyance is how it breaks all my saved data in the browsers. I'm using a mid-2014 MBPr.

I have MBPr 15 (mid2014) none of the peripherals mentioned above.

Did not have this problem with El Capitan.

Just started tonight 4/09/2017.

Broke saved data in Google Chrome, but it appears not is Safari.

The real annoyance is that I trusted to go for the Sierra Update.

Apparently a foolish idea.

Still cannot find an edit button ...

I decided to uninstall Adobe Photoshop Elements 15 as an experiment.

While nothing could be considered conclusive yet,

... for the last few restarts and reboots, the date/time bug has not repappeared.

Too soon, to be sure, on this linkage.

Will check it tomorrow after a long shutdown period.

My experiments with removing software installed result in

negative finding. Had another occurrence of faulty date and time

...

All I know for sure is that for a year running Mavericks, then El Capitan

my MBPro never had this issue, until a week ago installing Sierra

😟

Same issue here since updating to 10.12.4 on my mid 2014 mbp. Super annoying since I have to manually change the time server each time post boot so the correct time displays. All SSL certificates show out of date which breaks my ability to pull new email and browsing secure sites. Never had a problem until this most recent update was applied.

Can y'all verify that the output of the following command reporting login time totals has a huge garbage entry?

ac -d

For instance, that returns the following output on my Mac. Mar 29 being the date that I encountered the time issue:

$ ac -d

Mar 29 total -621151.16

Mar 30 total 24.00

Apr 5 total 143.94

Apr 6 total 23.95

Apr 9 total 67.58

Apr 10 total 23.98

Apr 11 total 23.97

Apr 12 total 23.99

Apr 13 total 9.62

Not sure how I can remove it, no idea how to really mess around with the asl logs or anything to clean it up

When I downloaded the update I was experiencing many issues:

- slow computer

- apps not working

- dock not showing

- dashboard not available

- safari not working

- desktop icons no showing

- and many other issues

I thought my computer was broken or had a serious virus on it. After spending multiple hours trying to figure this out. I had noticed my date was set for Dec 4 2040. Then I went into the date and time settings and it was displaying Dec 2 2037. As soon as I unlocked the date and time settings the time corrected it self, but did not solve the problem. I restarted my computer and everything went right back to the same problem. Then I changed everything to manual time and unchecked the box "set date and time automatically" and restarted my computer and now everything works perfectly! Apple will need to fix this issue with the next update, but this is what worked for me.

Go to:

- System preferences

- date & time and uncheck the box "set date and time automatically" and manually set the time.

- Restart the computer.

The problem will go away from what I am experiencing on my mac book pro.

Sorry for the late reply, atkin88, but your link to the drivers did the trick! It is all working now.

For the record, the problem with the date error only occured when cold booting, and not with a reboot.

In my previous post, I said that I was in contact with an Apple Senior Advisor, but unfortunately it took too long time so I had to remove the test partition where I could reproduce the problem (I needed the space for a production). So Apple did not get any logs from me. I believe the only way this bug can be fixed is if someone with some spare time can raise a ticket with AppleCare to eventually provide them with logs.

Best regards
