Same here, at least 10.12.2
I need to update again.
I don't turn on my MacMini Server very much any more, so I'm tardy. My plan is to upgrade the 2 each HDs to 2 each SSDs (sitting on the shelf), but I haven't had the time. Maybe after I get our taxes done (sigh).
In general, I try to keep things updated. Sure there are occasional bugs, but there are millions of users of this stuff so any serious bugs should be fixed pretty quickly, or have fairly easily findable work-arounds. It doesn't pay to put off updates any more.
J is a Mac person and has an iPhone 6S. Up until recently they worked pretty seemlessly, as they're supposed to. (She's suspicious of the Cloud and doesn't use it.) But for some reason she wasn't able to get her recent photos off her phone and into "Photos" on her Macs. "Photos" doesn't see any photos on her phone when she connects it via the USB cable.
The solution?
Take a photo with the phone connected to the Mac via the USB cable. All the photos on the phone suddenly show up.
:-/
She needs to update her phone software, too, but I'd be surprised if that buglet has been fixed. Pleasant surprises are nice!
Good luck, Ashton!
Cheers,
Scott.
