Hi folks, I'm trying to build communication between the main app and its helper via inter-process communication. I found here that it is possible if the apps are in the same app group. But I really cannot make it work, and cannot understand what I do wrong. It works all good if I add com.apple.security.temporary-exception.mach-lookup.global-name entitlement, so the setup seems to be correct? Where should I look to fix it? Also because having that entitlement means that it is gonna be tricky to get through the App Review.

I have an app that is distributed through the Mac App Store, and so is sandboxed. I need to fetch processor temperature, so some of its new features function correctly. Since fetching temperature is not possible in a sandboxed app, I was looking for a workaround. One idea that I'm investigating right now is having a helper app, which would not be sandboxed, be distributed separately, but be installed from the main app as a helper tool. Is that possible? Is that gonna pass the App Store review?
