I am upgrading a 2017 Macbook pro a1708 to a 2TB Fledgling Feather SSD, because the OEM SSD is full. After creating a time machine backup and changing out the SSD, i was successfully able to install Mojave, and restore the backup, but now when attempting to log in it stays on the login screen and the circle just spins, I've lwt it sit for 3 hours and it stays this way. When booting into recovery/utilities, the apple logo flashes a red box for a second. Any idea as to what could cause this? Switching the old SSD back in everything runs fine.

Is the MacBook running the latest firmware?

An NVMe drive with an adapter may be a better option?

I installed Mojave from the web so I assume it's up to date. And thats basically what the Fledgling Geather SSD is, its an M.2 on an adapter.

It could be that your MacBook needs a firmware update to work with 3rd party drives.

MacBooks have received several firmware updates since Mojave was released.
A quick update, I did a clean install without the time machine and it was working well, manually copied files over from the time machine, restarted the macbook and now it gets stuck with a full loading bar on the apple logo screen. Muat have something to do with thw files I copied over?

Could be, I'm really not sure.

I would not expect copying over data files would cause a problem. Sounds restoring the files does something to the start up process.
