Update to 10.12.4 causing Date/Time Issues

i still have the same problem like lanzenotter!! every second or third boot this problem appears. but i have not installed a 10.12.5 beta! is apple aware about this problem? this is a very anoying bug!!! is there any helpfull workaround!?

thanks for help

Thanks for posting this DaveGarrat. I've been googling around and this is the first post I've found that is actually related to the issue I'm having with my MacBook Pro 2014.

By reading replies and comments from others on this post, I think it's clear by now that this is not related to any driver or third party software. Doing a full OS reinstall doesn't solve the issue either (I've tried it as well).

I'm hoping that the 10.12.5 update fixes this, as others have pointed out. I'm just waiting for the final release so that I can get it, not sure about installing the beta version for now, since it may cause another different issue.

Update to my earlier post; I reinstalled 12.3 and set the 12.4 update to be ignored. I haven't had the issue once since reinstalling 12.3. Hopefully 12.5 is released soon, it seems that those running the beta aren't having the issue.

I could not go back to 10.12.3, for some reason. My only solution was to delete everything and reinstall El Capitan. As a result of reinstalling El Capitan, I ended up losing Siri, but my MacBook Pro is back to functioning properly, fast, and stable. Apple did something horrible in 10.12.4 and they owe us a big explanation!

Same problem like every one else, I have tried most of the same things, I also have problems

with Safari not recognizing web sites certificates.

This temporary fix works for me (till the next OS X upgrade),

at start up turn off Wi-Fi and then turn it back on and that correctly reset the time

and fix the certificates problems with Safari..

Good news, thanks for posting DaveGarrat.

I wonder why the patch description says it's an issue "affecting some enterprise and education customers"... I'm a regular user. But either way it's great know their addressing this in the next update.

GianniNYC: turning the Wi-Fi off/on sometimes works for me also, but it's kinda unpredictable, only works sometimes for me. So far I haven't found a way to reproduce (or even temporarily solve) the issue. I just reset the Wi-Fi, turn on/off the automatic timezone setting and restart the machine.

I have similar or the same problem - since upgraded to 10.12.4, date of my MBP 15" late 2016 randomly jumps few days to and fro, few times per hour. The time jumps randomly too. I have an Agenda app that detects date change and display question if I want to change display to another day, otherwise I may not notice how often this happens.

When opening Date&Time control panel, date and time jumps to correct value. Upgrading to 10.12.5 did not help.

I reset SMC and zapped PR and problem seems to went away. I do not know what caused it in first time, if it is caused by some software it can reappear, but since yesterday I did not noticed any jumps in date or time.

MBP 15" late 2016 with a lot of various software. Software that install system extensions ( so could have access to date and time setting) include Parallels for virtualisation, several VNC software, custom Razer mouse driver, dropbox and online backup system etc., however nothing was installed in last few days.

If you are using safari as web browser and google type :

Lot of videos are there , some using sudo commands .

Its better to reinstall the operating system once again , an article for it : macOS Sierra: Erase and reinstall macOS

Tried updating your ethernet drivers?
