So I Have a Firmware Locked Mid 2012 A1278 MacBook Pro. I was wondering could I bypass the EFI lock if I buy a new logic board to swap it out. Help me please! I was ripped off on eBay!
STOP! Contact seller & eBay ASAP! If the system is locked you need to get your money back here. You can’t reward theft by sucking it up by buying a new logic board to replace the locked one. eBay - Law Enforcement Reporting Depending on how you payed the seller you may be able to stop the payment. If you used a credit card talk with them some offer online purchase protection (i.e. American Express). eBays numbers: Customer service: 1 (866) 540-3229Technical support: 1 (866) 961-9253 Update (10/08/2016) Here is the IFIXIT guide you’ll need to follow: MacBook Pro 13" Retina Display Late 2012 Logic Board Replacement and here are two possible logic boards: MacBook Pro 13" Retina (Late 2012) 2.5 GHz Logic Board - Used $600 USMacBook Pro 13" Retina (Late 2012) 2.9 GHz Logic Board - Used $900 US You may need to replace the SSD as well here. I would get this SSD Enclosure for 2012 & early 2013 MacBook Pro with Retina display and you’ll also need to find a friend with a Mac so you can scrub the drive down and prep it up with a clean copy of macOS. If that fails you’ll need a new SSD as well.
