What is 'this end'?​Every piece of software I've used since upgrading including many older products that have been discontinued. Need a list Eric? Photoshop dating back to CS5, Lightroom dating back to 5. All color management software you don't own. MS Office 2011. Transmit, ScreenFlow, iBank and Quicken.

Everything running fine on this end. Back up your software fully before installing a new OS (and unlike Eric, don't get a virus and back that up too, infecting all your images and files). Update the OS and other software products if asked to do so. Run the products you use daily and confirm all is well as I did. Ignore the Eric generated FUD and just practice sound computing workflows.

I have a full backup of the last OS and all app's and files on a firewire drive in a fire proof save. I can go back anytime I might need to (but after a few weeks of work, no reason to do so). There's nothing earth shattering in Sierra. That's probably another reason why nothing seems to have broken as we've seen in the past with other OS updates. I do like the ability to set the menu's to black for soft proofing so I don't have to see the white of the GUI that Adobe can't control. Siri integration?

It's kind of useful but not a game changer. Dvd photo slideshow for mac. Don't need it on my Mac.

Here's some more info about what's new and what may or may not be useful to you: http://www.macworld.com/article/3083346/os-x/macos-sierra-faq-what-you-need-to-know-about-the-new-mac-operating-system.html. Or you don't and have no actual and direct experience, just google?

I thought about the Sierra update, but the Macs I use won't be able to utilize Sierra to the fullest. After looking at the upgrades, it's not for me. I'm happy with El Capitan on my 2012 Mac Mini and 2011 Macbook Pro.

Big, big difference Eric.​ Yes, most people would google and read what issues there may be before blindly installing a new OS on a machine that they depend on. With you going ahead and doing so on your cute little laptop Andrew, speaks volumes to people that actually do photography. Here's an idea, big shot. I'll grab some popcorn and observe while you come out from under this little rock called Photo.net and into the real world of Adobe's group on Facebook and tell these posters that everything is just fine. How do you carry on like this even after I post four links from page one of a Google Search result demonstrating that everything isn't 'hunky dorey'?​How do you carry on when multiple people with actual experience with Photoshop CC and Sierra, UNLIKE you Eric, post everything is working fine?

That was what the OP asked and he got several answers, all in agreement, from those with actual working experience. Something you lack. I'm sorry that reality and facts continue to ruin your life Eric. If indeed, ignorance is bliss, you must be a in a continual state of ecstasy!

With you going ahead and doing so on your cute little laptop Andrew, speaks volumes to people that actually do photography.​Poor, sad little Eric. He'd like the members here to believe that the size of one's computer somehow compensates for their knowledge and abilities. He probably doesn't want others to know he too, by his own admission, owns and has recommended a MacBook Pro laptop as I'm using. He probably thinks that by showing himself in his SIG/bio page here, holding a Hasselblad, that camera makes him a photographer.
