Early 2008 MacBook. Currently running 10.6 Snow Leopard, can be upgraded to 10.7 Lion upon request.
Additional pre-installed software:
-iWork
-Microsoft Office
-iLife
320GB Hard Drive
2GB RAM (Upgradeable)
2.1GHz C2D CPU
This would be a great machine for basic internet browsing, any PowerPC app compatibility (Snow Leopard was the last version of macOS with Rosetta PPC support) or anything about working with older Apple devices. They are also becoming collectibles in their own right.
Everything works. Battery is no longer charging, but shows good voltage and isn't swelling so probably just needs to be reset, or they're pretty cheap to replace. Take it for the list price with a charger, or $50 without one. It can be seen working either way.
Can be upgraded to modern macOS easily.
