Error enabling photo stream "iphoto was unable to connect to Photo Stream"

I was having the same problems, but with a single HD. Did many things, to no avail.

The log out/log in as another account/log out/log back in worked for me.

Apple support wasn't much help on the phone. Wanted me to to SMC and PRAM resets.

I tried the method above but iPhoto gave the error message with the alternative account. Still, I went through but it didn't work once I was back on my account either.

I have been tearing my hair out for months trying to get photo stream to work on my iMac. It works on my iPhone, iPad and MBP but not on my iMac. Your thought on it being Keychain related was spot on.

I reset my default keychain and after verifying my icloud account via email and enabling photo stream in iPhoto everything worked just fine. Thanks for the thoughtful information. This is the solution for an account on an iMac that does not allow iPhoto to connect to the photo stream. WooHoo!

Thanks pmarch, the process you provided worked like a champ for me. Crazy how the privileges would get confused. I am now happy that my iPhoto is syncing with iCloud again.

Im having the same problem with dual hard drives on my Macbook. If anyone gets an official fix for this please post it here. Thanks.

BTW, Mike's idea to change the deny to allow worked for me.

Thanks Ijanczar! I signed into my wife's account, turned on photostream, logged out and back into mine, turned on photostream, and...VOILA!!! Thank you so much!!!

this worked for me as well. just sign out, signed in with a diferent apple id ( my girlfriend's one ) just select yes to synch everything, and then sign out and resign in with my apple id. it worked. now sincyng streaming photos.

thanks IJanczar

Thanks IJanczar,

That worked for me.

I used my wife's account as a dummy, otherwise I followed your actions exactly.

For information my data is in the default position on my primary HD/user folder.

Answer : ~/library/application support/ilifemediassets, send to trash

note: make sure iphoto is closed before pulling to trash

- logout after trashing, log back in

i have the same problam and i am 100% shore its my user problam bat i cant pin point it :-/ dont get way apple is not adressing this problam.....

Dear Mike,

i run a ssd & hdd in my MBP2009 together and have the /Library linked on the ssd for performance reasons.

Before i patched my Photostreamagent.sb successfully after reading your post and everything worked for the photostream fine again.

Now the iPhoto 9.3 update came und i updated it and i patched the photostreamagent.sb again, but this trick is now no more working ... in the system.log i have these PhotoStreamAgent(7256) deny file-write-create messages again ...

Any hint or clue, how to get photostream working after the 9.3 update again?

Cheers from Germany,

Chris.

Hey peeps!

if you are still having difficulties with the 9.3 photostream activation there are a couple of different steps you can take

#0) Create Test account as admin in system preferences users&groups

#1) log into a guest or test(admin) account

if able to activate photostream, log back into main user

if not able, system wide errors are occurring so more troubleshooting will need to take place

option yes steps :make sure iphoto is quit, then go into the samefolder as before to trash ilifemediassets folder ^^^^directory posted above

after trashing the folder go to ~/library/preferences : trash com.apple.iphoto.plist (only this one), next you will eject your secondary harddrive and shut down the computer

turn computer back on, open iphoto, (yes with the external disconnected) once iphoto loads up quit the application from the menubar.

plug in external drive (give it a moment to recognize) after hold the option button on your keyboard, while holding option click on iphoto, keep holding down option until you get the option to select the library on the external library

attempt to reestablish connection with photostream

#if you got a no for the above result based scenario question

start computer in safe mode, hold shift at startup

uninstall and re-install iphoto using the App store if your on lion

I hope this is atleast helpful, and believe me I know the second option doesn't sound fun but most of the time it takes care of the issue as welll. Make sure you backup all your items always. Good luck have fun!

Thank you so much....I was sooooo frustrated attempting to get photo stream to work on my iMac....it works now!!!

thanks Vspad, you enlighten my day 🙂

your method fixed my issue..!!!

FWIW I fixed mine when I realised I'd probably downloaded iPhoto using an AppleID from the App Store but logged into iCloud with a different AppleID. I deleted iPhoto and it's related files (but not the iPhoto Library) using CleanApp, entered the App Store with my usual AppleID and downloaded iPhoto again. Once the App Store, the downloaded iPhoto and iCloud logins were the same iPhoto Stream worked again.
