Sync~ object in Max 5 becomes unsteady when my PSU is disconnected.

I tried it out, and some times when I disconnect my PSU from the Macbook after a little its starts to be unsteady.

by unsteady I mean that the output (audio and MIDI) manifests discontinues jumps in values.

Anyone experienced this?
