I have a MacBook Pro 13-inch mid 2012 with macOS Sierra v. 10.12.6 Some technician installed Samsung SSD 840 EVO 1TB for me on this machine. There was no problem until I tried to install MacOS Mojave.
After some reboots on the installing process I have this error message:
macOS could not be installed on your computer. An error occurred while verifying firmware.
I already tried:
- A) Install on safe mode
- B) Format, reinstall Sierra, try A from there.
- C) Run First Aid from Recovery.
I don´t have the original HDD.
