2012 Mid MacBook Pro

The 2012 Mid MacBook Pro is a very popular and well-regarded model, particularly the 13-inch and 15-inch non-Retina versions. This is largely due to its upgradeability and relatively low cost compared to newer models.

• Processor: Typically featured either an Intel Core i5 or Intel Core i7 processor (3rd generation "Ivy Bridge").
• Memory: Came standard with 4GB or 8GB of RAM, but is easily upgradable to 16GB.
• Storage: Included a Hard Disk Drive (HDD) or Solid State Drive (SSD). The HDD can be replaced with an SSD for a significant performance boost.
• Graphics: Used Integrated Graphics (Intel HD Graphics 4000) in the 13-inch model and discrete Graphics Cards (NVIDIA GeForce GT 650M) in some of the 15-inch models.
• Display: Non-Retina display with a resolution of 1280x800 (13-inch) or 1440x900 (15-inch).
• Ports: Included Thunderbolt, USB 3.0, FireWire 800 (15-inch), Ethernet, SD card slot, and a headphone jack.
• Optical Drive: It's important to note that both 13 inch and 15 inch model had a Optical Drive. Newer models do not include this feature.
• Operating System: Originally shipped with macOS Mountain Lion, but can be upgraded to newer versions of macOS (check compatibility).
• Upgradeability: A major selling point of this model. The RAM, HDD/SSD, and even the battery are relatively easy to replace and upgrade. This makes it a popular choice for users who want to extend the lifespan of their laptop.
