Has anyone experienced this situation before? Any lead would be very much appreciated.I went thru this same scenario, and chose to Re-install from Utilities However, we're very reluctant to do this, because if it doesn't work, we will need to wipe a hard drive and try to install High Sierra again.

Now, we how will the MacBook Pro read the 480GB SSD APFS as a bootable hard drive? This gives the impression that the laptop cannot properly read the 480GB SSD as a bootable Hard Drive. However, the top level was read as AppleAPFSMedia, and then the SSDName under it. The laptop was able to read the contents in the Finder, as well as list down the item in Disk Utility. I then inserted the 480GB into an enclosure, and then attached it to the laptop. I then inserted the 240GB SSD, and I was able to boot normally. I then rebooted the SMC and PRAM, and on the normal boot, I held the right option/alt key to see the bootable devices, but I didn't see any, which established that the laptop couldn't read the 480GB SSD as a bootable device. I was given the blinking folder icon which indicates that the laptop wasn't able to read the hard drive. What I did was I took out the current hard disk, inserted it on an enclosure, and gave it to her.Īt first, I inserted the 480GB SSD, but it wasn't booting. I have a Macbook Pro 9,2 that can't read an SSD that has a macOS High Sierra installed on it.įor the background context, a friend gave me her Macbook Pro for me to retrieve the files, and told me I can keep the laptop after.
