"Baseline attributes range start at 1 and can go
up to 6. That range is modified by metatype and/
or chosen qualities."
In other words, the limit depends but exists.
"During character creation, only one attribute
may be at the maximum for the selected metatype."
So there is an additional chargen limit, but the max rating always applies.
Meanwhile, Skills are a special beast because chargen max is not the same as gameplay max.
"During character creation, skills can be purchased
up to rank 6 (7 with the Aptitude Quality).
Only one skill can be put at that maximum
level (6 or 7). During gameplay, those skills can
reach 9 (10 with the Aptitude Quality)."
