Hi I have a Question:
I have a couple (Macbook Pro's, Air's and Retina's) all with (EFI firmware locks)
I'm pretty good with component level repairs and programming etc... I generally use a
(MiniPro TL866 Programmer) to program the EFI bios chips and I have a question in regards to editing a locked EFI Chip on the mac's
After desoldering a Macbook Bios chip placing it in the (MiniPro) reading
