Physical efforts in virtualization and mobility
So you’ve got a whole bunch of iPads out in the field hosting various applications and iOS9 comes out; one of the application vendors tells you his application isn’t quite ready for the latest OS and that you should hold off on updating your fleet. Problem – If you look for an option to disable iOS updates in your MDM suite you won’t find it, this is not a limitation of your MDM provider but more a control that Apple hasn’t provided to them. So if you ask your MDM vendor they will probably say it’s not possible, and as far as I can tell this is indeed the case. I’m going to keep looking but for now the best we can do is suppress the notifications that pop up advertising to all and sundry that a new version is available, but even this is not an out-of-the-box setting so I’m going to explain how it’s handled in AirWatch.
Now there’s nothing to stop users navigating through the menus to check to see if there is an iOS update, finding one and proceeding to download and update it themselves, so this is about as good as it gets for now. According to the comments this short article it is possible to use applednld.apple.com via a proxy server (although I think it should be appldnld.apple.com – note no ‘e’ on apple) to disable access to the download location but I didn’t have any joy with this. If I ever get any further with this issue I’ll post an update with the final solution.
