Q: I cannot receive pictures in iMessage all of a sudden.

Hi,

I have not seen messages/alerts like those.

Does the downward arrow allow you to Download the item ?
The File Transfer Window implies you need to download them.

I am having the exact same issue.  When I click the download arrow, nothing happens. It refreshes briefly but stops and never downloads.  I'm at my wits end in attempting to get online answers and nothing has worked so far. I have the same laptop and operating system as the gentleman in the original post.

Hi,

Do you Little Snitch ?

It is an app that act like a firewall as it shows you the Ports and IP addresses that an App wants to connect to.

There are other apps like this about.

Their main purpose is to Monitor and Inform but in some cases if you don't know a support process is involved then it can be blocked (or not Allowed)

This is the type of thing that pops up.

It is this File Transfer Agent item you need for iMessages File transfers (pictures are included in this)

In the Little Snitch App it is listed as two connections.

There is a slightly different named one for transfers via AIM and Jabber connections.

No, I don't have any program like that. Do I have to have it? I've never had one before and messages worked fine until a week or two ago. I have iMessages, as well as AIM and Jabber. I can't understand why I need to spend $40 for a program to fix a new Apple issue on a computer I've had for two years and never experienced before.

I have the same issue. It started about like a week and half ago and I don't know how to fix the problem.

Hi,

No you don't have to have it.

(It also comes with a trial version that lasts about 3 hours each time you boot the computer).

I was saying that if you do have one like this it can block but processes (sub routines in effect) that are connected to the App but not fully part of it.

I have just written another reply to a similar question in this thread Re: Messages no longer allows me to transfer images using AIM

I spent time seeing how it was working between my iChat 5.0.3 Snow Leopard computer where there have been no changes to the app and with my El Capitan iMac where El Capitan has received Updates.

The outcome was not good.  AIM only seemed to allowed Zipped (Compressed ) Pics.

Sending in folders worked sometimes but not as often as Zipped files.

I must admit I am not seeing the same messages in the File Transfer window as the Original Poster.  They either work or go straight the "Failed".

I am having the same problem. I can't get pictures on my MacBook Pro Retina 10.11.3. I see them on my iPhone but not my MBP.

Hi,

Have you tried Zipping the file ?

Same problem here, happened all of a sudden. I'm getting this for every photo sent. Maybe we have to wait for a new update. It is quite annoying hopefully it can be fixed soon

Hi,

I have not seen that error messages before.

Have you changed something ?

There is an App called Little Snitch that monitors and makes requests about every connection an App will make  (if you set it up that way).

There are several support processes to Messages that can get blocked this way if you don't realise they are required.

Little Snitch is not the only app that performs this sort of check or Firewall  type behaviour.

Hi Marisa,

same problem with me with MACBOOK PRO 15 OS 10.11.3

I cannot receive anymore pics in the App Message on the computer, but on my iPhone everything work.

Anyone have a clue?

Thank you

Hi,

In System Preferences > Security and Privacy  is the Firewall On ?

If so is Messages allowed ?
