My new SSD is not recognised in my MacBook Air when trying to set it u
I have purchased a MacBook Air early 2014.
the previous owner kept their hard drive for data safety so I bought a OWC 240gb SSD.
the MacBook Air doesn’t recognise the SSD. The box of the SSD and some searching on the net told me I need to update the firmware on the MacBook Air.
I have a 500gb 2.5” SSD from my old broken laptop and so I connected this with an external USB adaptor to the MacBook Air and it booted and worked fine when I booted up and pressed the option key. I could use the computer perfectly.
I then went to the App Store and downloaded OS X Big Sur which states it is compatible for my MacBook Air. It took a few hours to download and install but on the final reboot it stopped working.
ive tried to set up the new SSD but have the same problem as originally. Now the external SSD will not boot up and I can’t get it to show when I press the options button.
my data is not important. I want to set this up as a new MacBook Air. I have a separate time machine back up of my data.
I am happy to start this procedure again and give up the OS and data on my external SSD.
I can run disc utility etc by pressing COMMAND R
thank you in advance
