Hi, Hello, Good Afternoon!
My laptop is Macbook air 2017 13" A1466 i5, 8gb, 128gb
I have decided to installa new ssd (Samsung 512GB SSUAX MZ-JPU512T/0A6 655-1805D) into it, because there was not enough space on the original one.
Unfortunately, Mac didn't recognized it at all! 🙁
So, I've put original ssd back in (with all files and Big Sur OS) but I've noticed that there was blinking folder icon with a question mark.
I've tried resetting NVRAM, SMC and PRAM, but with no effect!
What should I do? Help me please!🙁
