Enable SMS Forwarding between iOS 8.1 and Yosemite

No code's shown on Mac?

Me too. 

I have this solution after googling  DuckDuckGoing. 

here the excerpt 

I've found a solution on another forum and it worked for me:

Try this: Go to your iPhone Messages settings and turn off iMessages and turn it on again. Then go to the iMessages Settings on your Mac and do the same. After that it worked for me. Also make sure to activate your telephone number in the iMessages settings on your Mac.

and yeah, it works, :)

Stuck on "Upgrading" iCloud Drive

Well, nothing we can do about it.

But, just remember that sometime the process time on apple based device (and others platform as well) didn't as reliable.

The "1 minute remaining" installation message that took 2 hours to finish.

The Mail app sending message that tell "34 minute remaining" but actually it's sent and we got bewildered when receiving reply of our message that "didn't" sent yet.  

So, be patient, :)

You could soft reset it, power-off and then turn it on again, or another reset, press home button and power button at same time until the device turned off and boot by itself.

Got some solution from discussions.apple.com, flip the airplane switch to on, it'll gave the error message, flip it to off again, and all is well, the iCloud drive status is on. Weird, not pretty solution, but worked, so no problem for me.

But that won't guarantee the problem is solved for everyone, :)

Some succeed by using it and some didn't.

The alternative is, again, be patient, :)

I used it on my OS X Yosemite, still prefer Anagram+Anvil/Appear combo though, :)
