While I was painting along, all of a sudden a rattling sound emerged from my mac.
I soon realized it must be a insect which is trapped in the fan , so shut down the comp as fast as possible.
I spotted him immediately and managed to get him out, it wasn't easy.
He was still running in circles inside of the frame and couldn't get enough grip to climb out through the wholes.
With a brush I could give him enough to get a grip and he barely made it out.
After that he rested on the brush for a while and didn't move. What a ride on the rotating fan that must have been for the poor guy ( or lady).
I brushed him with a soft brush a bit and after a while he started to clean himself. He's well and gone now.
