Q: Can't open any iCloud documents on mac

come on there has got to be an answer for this! this happens on El Capitan too, with documents generated on an iOS9 device (and they open file there)???

Same problem here.  In Yosemite was able to get it to work again by going to iCloud in System Preferences, unchecking iCloud Drive, rechecking it, and allowing all files to re-download. Unfortunately, even that does not seem to work since El Capitan.  Copying the iCloud files to your hard drive and back again might be the only solution for now.

Again, same problem.

I have the same problem. 

OS X El Capitan 10.11.1

It's becoming a major issue for me - iCloud is nigh useless if I can't use it across my devices...

I have the same problem. 

OS X El Capitan 10.11.1

I restarted my computer, and like "magic" it started working again.

@balitmoreappleuser Are you sure that restarting the computer is all you did?  I'm sure most having this problem have tried that.  I know I have, and it's the same problem across four machines.

It worked perfectly for me. I did exactly what siisaul did, with the minor exception of shutting down my mac and turning it on 2 minutes later, and it started opening my icloud files again.

I had this happened 3 times with an Xcode project on iCloud Drive (Yosemite 10.11.2). In each case restarting the computer allowed me to open the file but it's annoying to have to restart and does not inspire confidence that your important files are safe.

Hi

any update on this - i see exactly the same issue.

PDFs open fine

PPT provide an error 'the document "(null)" could not be opened

WORD just won't do anything

can see all in finder preview

can download from iCloud.com and save locally to open.

thanks

Restart worked for me too.

Total reboot worked for me. May 2016. Latest everything.

Other than rebooting, nothing seems to "fix" this issue.

rebooting worked for me. it's annoying.
