Not sure if this is how to get at it:
ls /Library/Frameworks/Mono.framework/Versions/ 2.10.1 Current
from the terminal you can run
mono --version
to get it. If that is less than 3.2.6, can you try installing 3.2.6. Technically that is what we bundle with and it should already try to utilize our bundled version if we detect less than that, but it won’t hurt for you to try the actual installed version and let me know if that fixes the problem.

Thanks, mono, is not currently in my “path” so I have to go directly to where the executable is expected to be. I know that Unity installs mono as well, do both UE and Unity install mono in the same place (is it shared)? Or is there a specific path that I should check for the mono that UE4 uses?
We use our own bundled version and don’t actually install it. I don’t think that’s the issue anyway. Still trying to find a possible culprit.

Ok, I may have tracked down the AFCFileRefOpen error 7 to being a bad conversion of a string. Specifically, the public staging directory name on the device. Your device wouldn’t happen to be setup for a language other than English would it? If so that might be the issue (and we would need to fix on our side).
-Pete
Is Canadian English different than English 
No, but we have had bugs related to different languages and cultures before. After experimenting, error 7 (the one I am seeing in your log) is either a null path or a path that is not being encoded properly. Not sure yet which it is though.

Thanks, I installed a new version from mono, but as you guessed, it had no effect.
Well, I’ve been unable to figure this out and I can’t seem to reproduce. So, I am going to add some more logging to the deployment server so we can hopefully get enough information to track down what is going. Unfortunately, that won’t show up until 4.7.3 which I don’t have a release date for.
-Pete
Howdy vbs,
I am going to be marking this issue as resolved for tracking purposes. When 4.7.3 releases, please feel free to reopen this issue so that we may be able to further investigate.
Thanks and have a great day!
So, in the course of helping another with this issue, I have found a fix that works. That fix will be in 4.7.3.

Hi,
I am having exactly the same issue with my iPad. I am able to reply to iPhone, but not to iPad.
I am using Version 4.7.6-2513093
on OSX Yosemite.
I am trying to launch a development build configuration
My Log:
mono: System.IO.IOException: AFCFileRefOpen (/PublicStaging/bbzet.ipa) failed with error 7
Howdy romfeo,
Thank you for reopening this issue. Would you be able to attach your full log to this post? Could you also provide the exact OS version your mac is on? Would this be a Binary or Source build of UE4?
Any additional information would be greatly appreciated.
Thanks and have a great day!
