Macbook pro 2011 15 inch

  

MacBook Pro 15.4 inch display. 250GB ssd (crucial mx200)+ 500GB HDD (toshiba) gratis. Freshly installed Mac OS High Sierra on both discs! Working ONLY with power adapter. The second thing it is slow.

I have already the same model a year ago and it was much faster so maybe need a clean inside, maybe new thermal paste. Collection in person from Stevenage.
