Chosen Solution
Hello, bought this mac book online without battery, SSD and charger, so I bought those parts separately. I am trying to install MacOS, not being successful. The first attempt was Mojave from a USB flash drive and crashes during installation rebooting and entering in a loop. Then I tried high sierra and same error. After tried to internet recovery mode but it doesn’t recognize my SSD. Next day I took it to a apple certified store and they were not successful and said that might be a bad drive. So, I returned the drive and I got a new one (same one) and now I have the same problem. Here is my question: today I was reading that the SSD in order to be recognized, the laptop need an EFI firmware update. 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. I have a couple Ideas: 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. Good idea?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 way to update the firmware form a USB flashdriveReturn my laptop and find a new machine. I don’t want to do this bc the baterry is already glued :( Any guidance please!!
Regardless of firmware updates, if you got a High Sierra or Mojave Bootable install Pendrive you should be able to see and format the flash drive you want to install to with Disk Utility and then be able to perform your install. Either you have a faulty flash drive or a faulty logic board. The fact that you cannot install from Usb either, suggests the second option as the most probable. If you have the chance to, return the Macbook.
