Photoshop 2017 and Wacom Intuos Art (OSX)

i don't know if you solved your problem with Wacom issue. I was trying to find the solution here but failed.
However, I figured it out myself and would like to share with you.

1. go to Adobe Photoshop CC 2017/Locals/zh_TW (I'm from Taiwan, yours must be different~no worry there's just one folder here)

/Support Files/Shortcuts/Mac

2. you'll find the file "Default Keyboard Shortcuts.kys"

3. just double click on the file

4. then you'll find all ExpressKeys are back

Thanks to grcouch​ and other people trying to rectify my issue. As grcouch said Wacom not updating properly their drivers properly. богданс32134874 Bro its worked from your trick ... Thank you very much

To get your tablet and pen to work in photoshop 2017 on mac. plug in tablet system>preferences>ink> uncheck handwriting recognition, allow me to ink in any application, and show ink window. Should work.

I am experiencing a similar conflict problem between Sierra (10.12.1) and PS 13.0.6.  In my case since I down loaded Sierra none of my keyboard short cuts will function on PS; the shortcuts work with ALL of my other apps (Microsoft Office, Lightroom, Acrobat Pro, Affinity Photo, etc).  To further confuse the issue, when I first try to open an image in PS and see the Camera Raw 9.1.1 window, the short cuts work, it is only after I select "Open Image"and the image opens in PS do the short cuts ceased to function.

I had this same issue, but it happened when I crossed over to Photoshop CC 2015.5 on MacOS Sierra. All the express keys stoped working as did the pen pressure. I also have an Wacom Intuos (Photo/Small) which I use any time I bring my photos from Lightroom into Photoshop. I spent weeks communicating with Wacom support, trying to discover the root of my issue. We tried the latest drivers, rolling back to old drivers, and everything in between. I tried creating new application specific express keys for CC 2015.5 but nothing restored the functionality.

Oddly though, it appeared to be a Photoshop issue. All my Lightroom specific express keys worked flawlessly. What I ended up doing was rolling back to Photoshop CC 2015 on my own and the issue was fixed. Wacom support said they'd added the issue to the list of fixes for the next driver release, but I've been hesitant to update to Photoshop CC 2017 for this very reason. They haven't provided great driver support so far, so I'm not shocked that your tablet isn't working with CC 2017.

What I can tell you is that Photoshop CC 2015, MacOS Sierra 10.12.1, and Wacom driver 16.3.17-5 are working with my Intuos. CC 2015.5 is what broke the express keys. Since you have Adobe CC, you might want to try rolling back to an older release of Photoshop like I've done. Broken express keys severely hinder my workflow so for now I'll be sticking with my current configuration. Seems like transitioning between versions can cause some big issues. I might give what DavidSpieth​ did a try and see what happens.

I don't have experience with the Mac, but have you checked for a later driver from Wacom?  If you already have the latest driver, uninstall it and reinstall to give it a chance to find CC 2017 and focus it's location.   

I'd be inclined to wait a wee while before reinstalling the driver though, in case someone with first hand knowledge of your OS comes to the thread.  We need to know what version of OSX you are running?
