Hum from my MacBook when connected to amp

[krivingus]

Hi guys,

i wanted to connect my macbook with Native Instrument Massive installed to my Boss looper to loop some synth as a play-along, but every time i connect it to the looper, or my boss ME-5OB, or directly to the amp, i get annoyng buzz, the sound is very quiet and distorted. The cable is ok, when i tried to connect my MP3 player to my stereo, it was working perfectly. Can you help me?

Cheap version: unplug the computer from the power supply.
