macbook ssd upgrade snag
Hello,
I have a mid-2012 MBP that I’m upgrading the SSD and going with Mojave OS. Using a crucial MX500 2TB drive.
I used a bootable USB to format and install the OS. I formatted to APFS as recommended online and installed the OS. When booting externally it booted fine. When I did the swap to the internal drive slot after powering on I get a folder with a ? in it.
Laptop booted fine, however very very slowly from the old Toshiba HDD so I assume the SATA ribbon inside is okay.
Did I perform this wrong. Can this machine run an internal drive on APFS?
