Apple Internal: false? Does anyone know what it means?

Yes, an Apple developer with access to the iOS data dictionary and a log file processing application can determine what it means. Mere mortals like us don’t have a snowball’s chance in heck making sense of any diagnostic log.

That looks like a startup process that first defines a set of properties, then defines a set of services to be started.

Apple_internal:false is a boolean parameter that says whatever is being started is not an Apple process.

But without knowing what process is being invoked you can’t learn anything. But even if you knew what process was involved you still couldn’t learn anything from a parameter list.

Google search for "AppleInternal" turns up mention of folders on some Macs and iPhones that store tools that Apple engineers use for internal development and testing purposes.

I can't find documentation for that property, specifically, but I think it probably indicates whether the phone has one of these AppleInternal folders (which might be the case only for a phone belonging to Apple, that's running internal firmware) – or whether the phone is internal to Apple and might have prototype hardware – or something like that.

So it would be normal for the property to be false on production units running production firmware.

I don't think that "AppleInternal => false" means that you have a fake iPhone.
