Internet weirdness after 10.11.5 upgrade

Thanks for the suggestion. Sadly it didn't work because the buttons to reset the defaults were greyed out. Perhaps this is because it can't reach Apple's timing servers.

Hi

Thanks for all those suggestions. I changed both time and date settings and then restored the defaults; I reset the NVRAM and the SMC and it still thinks it's 2001. I've also noticed that it's not downloading pictures in Mail -- perhaps because of the certification thing?

I'm going to research how to get hold of an El Capitan disk image on one computer to transfer to the MBP and reinstall.

Happy to hear any more ideas you may have. I'm grateful for your help.

Hi

That sounded a really great idea -- I felt sure it was going to work. But alas no, no effect…

Yes, I have that set. It currently thinks it's 2 January 2001 (the problem started yesterday). Interestingly, the time is only an hour and four minutes out, and the hour is accounted for by daylight saving (operating now but not in January). Of course, that could be coincidence -- even a stopped clock etc…

Solved the problem with help from Apple Support. The apparent internet problems were caused by the date and time setting which was earlier than the start date on the internet certificates of the various sites and services that weren't working.

The real problem was the automatic updating of the time that just wasn't working. I deselected that option, set the time manually to the correct time to the minute and switched the auto updating back on and all seems well. I have a residual suspicion because two different laptops with identical settings are showing different times by 30 seconds. I know the server's working because if I manually change the hour then switch it back to auto the hour is immediately corrected. I'd expect the time server to do the same with the seconds value, but perhaps it doesn't.

Thanks all for your help.
