I think bethelock was looking for information on how the key cuts can be arranged for that particular lock; MACS stands for Maximum Adjacent Cut Specification... it's a limit that the manufacturer specifies, and it defines the maximum "difference" that you're allowed between two adjacent cuts on a key.
For example, if you have a lock with a MACS of 5, then a key cut to depths of 16161 would be fine: the distance between the "peaks" (the #1 cuts) and the "valleys" (the #6 cuts) is shallow enough. If violate MACS for that particular lock, though, and you try to cut the key to 19191 (which has a difference of "8" between adjacent cuts) then either of two things might be true: (i) the slope on the key cuts may be too steep for the pins to slide over easily, and it may be very hard to insert/remove the key; and/or, (ii) the angle of the cut might be too steep, and the deep cuts might remove too much material for the shallower cuts to be even possible. (I put together a quick diagram that shows this second problem, below: the two deep cuts have removed too much of the key blade for cuts in the "red" area to even be possible.)
Ha... sorry, I see keysman replied while I was typing this and messing about in Photoshop. Well, what he said too.
@bethelock: I'm sorry... I've had a look through my various Depth/Spacing guides, and the closest I have for this lock is CISA's Keying Components catalog, which doesn't list any MACS spec.
