Photostream constantly turning itself off

What is your normal workflow that you are exercising when you see this? Do you switch users, or iCloud accounts, or libraries? Does toggling PS off at the server help keep it up and running afterwards?

I have the same problem: photostream turns itself off in Aperture, seemingly at random, without notifcation, about once every two weeks but not on any regular basis. It remains on in my iPhone.

The problem did not get fixed in the most recent AP update.

It's a nuisance rather than a disaster, but it makes keeping photostream up to date a labor intensive rather than a background activity.

Ian - Do you see any messages in the Console application related to Photo Stream?

There are 30 or so meesages in the past 48 hours that include the string 'aperture' - is there something in particular I should be looking for?

Me too! I have photostream turned on in iPhoto and can see all of my photos. All seems to work OK and pictures from my Iphone appear very quickly (although for some reason 1 photo on my phone never transferred?).

I usually shut iPhoto down when I have finished using it and usually shut my MAC (using Lion) down when I have finished using it. More often than not the next time I use my MAC and go to iPhoto I have to restrat photostream - most annoying!

Macorin, same problem here, however I spotted a log entry in the Console that might shed some light there:

... Aperture: FAILURE: Job com.apple.photostream-agent is not loaded in launchd

I searched the Console for Aperture right after getting the same "Do you want to turn on Photo Stream" error. Well, not error, but it is now a sign of an error somewhere there.

I wonder if we all have the same entry in the Console.

Peace

I am having the same issue. It is very annoying.

I see some people are having the issue in iPhoto as well. There is a thread about it here: https://discussions.apple.com/thread/3454674?start=60&tstart=0

There doesn't seem to be one solution for all and I am not sure if any of these will work with Aperture.

It seems like a bug that needs to be fixed somewhere.

wrong thread

How come Apple can't get this basic feature of a signature new feature like Photo Stream working right. Every time I launch Aperture, it has forgotten my Photo Stream info and gives me the welcome screen asking me to enable it again. EVERY. SINGLE. TIME. Give me a break. There have been multiple point-version updates to Aperture since Photo Stream was released and they still can't fix this.

Same problem over here and it was annoying the **** out of me… but after a restart Little Snitch asked me permission to access 'PhotoStreamAgent'. Aha… I thought and gave it permission to allow any connection with this server. Opened Aperture… and boom! the stream was turned on again!

So a possible solution could be to not block the 'PhotoStreamAgent' in any kind of way with Little Snitch or similar tools.

Posted possible suggestion here.

A Mountain Lion install solved this problem for me.

Forget it.

Backup before you try.

Just tried this.

I navigated to ~/username/Library and delted:

com.apple.photostream-agent, and

com.apple.cloudphotosd.

Restarted the computer and it came up first time and the next few times. Time will tell.
