I just cloned my HDD to a new Samsung T5 that I got today. I used Disk Utility to format the SSD as APFS GUID since I've already upgraded to Mojave. I then used Carbon Copy Cloner to clone the HDD to the SSD and tried to reboot. When I hold the Option Key, I get to the startup selection, but I cannot see the SSD, only the internal HDD. I've cleared the NVRAM and that didn't work either. I can see the drive if I go to System Preferences -> Startup and I can select the drive, but, I want to make sure everything boots before I change the default startup disk. Like I said, if I hold the Option Key down, I can only see my HDD and I've tried several times. Any ideas or help?
