I don’t want to do this bc the baterry is already glued :( Return my laptop and find a new machine.find a way to update the firmware form a USB flashdrive.The read a little bit that there are some methods to connect 2 laptops with fire-wire and then magically clone the drive or do something.find a friend that have the same model or late 2013 or mid 2015, borrow the SSD from the other laptop, put it in mine and there from the OS install the firmware and then put back my SSD and should work just perfect.In some websites are methods described to install the firmware when you are running Mac OS, but I cant install Mac OS, so I was wondering what other options I have to update the firmware. Here is my question: today I was reading that the SSD in order to be recognized, the laptop need an EFI firmware update. So, I returned the drive and I got a new one (same one) and now I have the same problem. Next day I took it to a apple certified store and they were not successful and said that might be a bad drive. Then I tried high sierra and same error.Īfter tried to internet recovery mode but it doesn’t recognize my SSD. The first attempt was Mojave from a USB flash drive and crashes during installation rebooting and entering in a loop. I am trying to install MacOS, not being successful. Hello, bought this mac book pro 2014 15' online without battery, SSD ( bought OWC Aura Pro X2) and charger, so I bought those parts separately.
