New SSD cant be read after install.
I tried so many things.
Orignal drive works but slow so I wanted to upgrade. I was upgrading the drive doing it via a High Sierra bootable drive I made on my iMac but that doesn’t work. I pressed OPTION on the keyboard and the Installed icon came on. I pressed it and it disappears and thats it. Tried this many times.
I decided to put this new Samsung EVO SSD (250G) into my optical drive on other laptop (17” MacBook Pro) I successfully Loaded High Sierra on it. Tested it by restarting and it loaded.
SO I decided to install this SSD into my 2009 Macbook Pro but all I got is a flashing Question Mark!
I tried using another older SSD. It worked so I decided to wipe it and reinstalling a clean OS-X using Command+Shift+PR etc… It detected El Capitan as the OS-X to reinstall. It wiped the old and started the install the new but was abruptly by a message saying:
‘‘‘This operating system cannot be installed on this computer and to contact the manufacturer etc….’’’
I’m experiencing a lot of inconsistencies. The New SSD works on my 2010 macbook but not on this 2009 MacBook Pro.
I did my research and watched many YouTube videos showing this working. The cables are fine as it reads older drives. Now that I wiped the older SSD I have no drive that works.
Frustrated. PLEASE HELP.
Esta é uma boa pergunta?
