15" 2010 MacBook Pro i5, 4GB, 240GB.From the 'sweet-spot' of the unibody Macbook Pro s; 1st gen i5 more powerful than the earlier core 2 models, but doesn't suffer the GPU failure issues of the later ones.Battery reports at 82% of original capacity - not bad for 16 years old! (apple warranty only covered less than 80% in first year of use)Currently running high sierra, though Ive had linux mint 22.3 running fine on it (speed was OK, but if you want a more responsive modern feeling OS of course a cheap SSD and maybe more ram work wonders).Cosmetically one corner dented, a few minor scuffs to the bottom, one deep scratch on the top and some more lighter ones.Otherwise good, screen and keyboard/area around it look great.
