Hi Bn02fly,
Firstly, I did the tests on a macbook air - no problems at all.
I did most of it using my laptop's touchpad to be honest. The only part I really felt I needed my mouse was the 'hand-eye coordination' test, but even then it probably would have been fine using the touchpad.
You can definitely do the 2 behavioural questionnaires, the verbal and numerical reasoning, and spatial orientation with the touchpad no problem at all, and those will take up most of the 2 hours anyway!
Good luck
