If you have inside goss on the inner workings of Apple Incorporated, you and I would get along great talking ‘inside baseball’ on Apple, because I love talking about Apple.

“Inside baseball” is one of my favourite Americanisms, it’s a figurative adjective meaning the details are appreciated by only a small group of insiders or aficionados. It usually refers to a detail-oriented approach to the minutiae of a subject, which requires such a specific knowledge about what is being discussed that the nuances are not understood or appreciated by outsiders.
