HI all, I recently bought the Transcend SSD 855 480 GB SSD upgrade for my MacBook Pro retina 13” mid 2014 (A1502) My system was on Yosemite, I had reformatted my original SSD and installed Mojave on it. I replaced my SSD with the new one but it was not showing up. I also tried to run the cmd but it was not detected. I then put back the original SSD and booted up the system, connected the new SSD using Thunderbolt port and it was showing up in Disk Utility. I followed the instructions and erased the Transcend drive and then installed again on my system still same issue I noticed that on the recovery mode when I try to select the option reinstall OS it gives the option to install the older Yosemite and not the new OS Any suggestion? Thanks
OK lets see if we can break thru the gordian knot you have your self in. Yosemite file system requires HFS+ When you upgraded to Mojave the installer upgraded your SSD to APFS in addition it also updated your systems firmware so APFS volumes can be booted. The hidden recovery partition you still have for some reason is still setup for Yosemite. You’ll need to use the Internet recovery services to configure your new SSD About macOS Recovery. Here we want to use the keys Option-⌘-R to get the latest version installed with the new SSD mounted internally in your system. Once you get the OS installed you should be OK.
Hi Dan, once the computer firmware is APFS upgraded with Mojave is it possible to boot this computer with a HFS+ OS or we’re stuck with the APFS settings ?
