Are you saying that a mystic adept is not allowed to initiate unless his or her magic rating is 6...?

Till this moment I was for some reason understanding it that way, but as it seems now, I am wrong from the get go. Thanks!
I finally, finally, finally understand it, even though we had a conversation about this already in a previous thread, I couldn't get the underlying mechanic of why Mystic Adept has a 2 point "deaf" space between Max Priority table and Max Attribute level. Now I can see the trade-off and the way to build more Adept focused character with a bit of magic and a Magic focused character with a bit of Adept. I could not see this before as it was elusive to me.
On one hand I feel like an idiot, on second, If I wouldn't ask and be a newb nuisance, I would have a hard time grasping it.

Nice

Side question: if a mystic adept chooses a mentor spirit do they get all three bonuses (All, Magician, Adept)?

No.

SR6 p. 162 Mentor Spirit Archetypes
Mystic adepts must choose either the adept or magician advantage at the time they accept the mentor spirit, and that choice cannot be changed.
