I'm really struck with the references in this show. As an aside, it's a really enjoyable show. And this time, unlike Lost, I expect to be let down at the end, and am just appreciating the ride as long as I can til it goes dumb. It's also awfully familiar to some other recent shows, like Homecoming and Loki. I've only just finished ep 2. Thank you, red letter media for the introduction.

Interesting references:

Mark Scout looks a lot like original macintosh era Steve Jobs.
Lumon -> Lemon -> Apple
using a logo without text. Also, the teardrop, if you squint and abstract a little, is like an inverted apple with the bite gone
corporate aesthetic is like evil Jony Ive Apple (I've heard tell it's not unlike 60's IBM), not counting the old testament painting.
founder's cult
I feel like I'm forgetting a couple.

Non Apple references:
Portal (and portal 2): opening animation, instruction books

The Matrix: scary codes on a screen, black goo

The Cube Series: general plotline (I am only on ep 2, mind you).
