I have a mid 2009 13-inch MacBook Pro, 2.26 GHz Intel Core 2 Duo, 4 GB 1333 MHz DDR3 RAM, NVIDIA GeForce 9400 256 MB, running Mavericks. Unfortunately the battery needs service after 605 cycles. It shows a full charge of 4148 mAh. The HDD IS 160 GB. The case is in perfect condition, free of dents or marks. The screen is also perfect, no problem with pixels.
