From Start-up Chime to Login Screen in About 14 Seconds. The above average cosmetic condition of this unit, as well as its relatively low battery cycle count of 159, suggest that this mid-2012 MacBook Pro has been gently used and well cared for. Don't forget: Apple engineers designed the 2012 MacBook Pro so it could drive a second/external display with a maximum resolution of 2560 X 1600 as either a mirror of the MacBook Pro's Display or as extension of it. Using the built-in Thunderbolt port and without any additional hardware or modifications, the 2012 MacBook Pro will drive a quad high definition (QHD) display such as the Apple Thunderbolt Display (A1407), the only display I know of with a built-in MagSafe charger designed to deliver a reliable 85 watt charge to the 2012 MacBook Pro.
A Prime Candidate for the "OpenCore Legacy Patcher". Did someone ask about running Apple's latest macOS 13 on a 2012 MacBook Pro? Good news: With its upgraded specs, this MacBook Pro is an ideal candidate for Dortania's OpenCore Legacy Patcher (OCLP). One such scenario might be as follows: Reformat the SSD and give it least 2 partitions.
On one partitions, macOS 10.15 (Catalina) would be installed and serve as the official "Apple-sanctioned OS" start-up drive. On a second partition, an instance of macOS 13 (Ventura) would be installed along with OpenCore and its machine-specific patches. Apple Model No: A1278 (EMC 2554).
