Concurrent calculation of Fibonacci in Elixir up to the 1200th position (faster than you can see)

It uses a known formla to evaluate a position instead of calculating it in a sequencial and/or recursive approach.

It's amazing how fast it is:

Remove Apple MDM

Note: Apple will store Wifi passwords on the T2 chip. SSD cleaning won't make it forget the password. You have to turn the network off, or change the password on the router.

Different Paths

Start from Path 1. If you get any messages about the MDM on the first usage, start all over from the Path 2.

Path 1

Get into recovery mode (Cmd + r) during start up.

	TRUE = λx. λy. x
	FALSE = λx. λy. y

	AND = λb1. λb2. b1 b2 FALSE
	OR = λb1. λb2. b1 TRUE b2
	XOR = λb1. λb2. b1 (b2 FALSE TRUE) b2
