I want to import in the ''masters' folder, it continues to say what follows in this screenshot
You first need to import a copy of the "Masters" folder.This is a read/write protected folder so need to duplicate it first then only Lightroom can read it.
First, you are using Lr's import plugin, and that does NOT work with Apple's Photos application. It works with iPhoto and Aperture.
Second, 20160103-054847 is an alias. Not a real folder. And it is being used by something, maybe Photos. Was Photos open when you tried to import? It looks like the end of a path like /Users/you/Pictures/Photos Library.photoslibrary/Masters/2015/05/27/20150527-175908, right? inside the Photos Library package?
I don't understand Akash's advice quite, but it seems like you are using an alias to access the innards of the Photos Library. This can be very dangerous, and the fact you're having trouble already causes me concern. You change something in either program and BOTH could have problems.
I think Akash is suggestion that instead of using aliases to actually mess with the innards of the library, that you COPY that masters folder out to say your Pictures folder. That's essentially what the Lr importer for Aperture/iPhoto does. You get duplicates, but it's much much safer. AFTER you copy it you import it into Lr. It's structure would look like this:
Those are dates: May 27, 2015 for example.
