Another Mac App Store issue...
I ran into an interesting App Store related hurdle this evening. I probably heard this before, but had forgotten since it didn’t apply to me at the time. Basically sandboxing and iCloud access go hand and hand — there appears to be no way to have one without the other.
I was experimenting with adding iCloud access to Composer v2. It works great - the file open/save dialogs immediately give you access to any files that you have saved to iCloud (whether from another Mac with Composer, or from an iOS device). When I tried testing on my other machine, however, the app wouldn’t launch.
I finally figured out that enabling iCloud in the non-sandboxed version of Composer is a no-go…. Which is unfortunate.
