The laptop still holds charge and will run for an hour or two on the battery. It currently has MintOS installed (Linux) but if you buy it I'm happy to re-install OSX before shipping it. There is an SSD installed and it runs fairly well. Please note the various issues noted below: Please note: Used laptop. There are areas of condition to note which include:The screen holds (as pictured) but it is looser than it was originally.One of the RAM slots doesn't work, but has 4GB currently installed.The microphone doesn't work - I've not investigated it further so may be fixable. Since new I have replaced the charge port and the motherboard. I have re-applied thermal paste and cleaned it internally, so no overheating. Comes with mains charger.
