First we have to visit Sheffield Apple computer shop to rescue Jim's Laptop which had a terminal battery expanding Universe situation last week. Fortunately it was still in warranty, They have just about rebuilt the whole thing in four days. Fetching it back for him is one way we can repay our in house technician for all the work he does on our computers.
