I guess I wasn't clear.

Okay, even so, the OP couldn't get the installer to finish the clean installation. Although a mid-2012 MBP is high at the bottom end of Mojave compatibility, that doesn't explain the impossibility of the installation. Plus, he used Time Machine and restored OS X 10.9.2 (Mavericks, assuming it's what he meant by "OSX 9.2")), which is far older and well within the capabilities of the machine, and it was still slow, so Mojave and software creep are not the problem.

It's possible I'm misreading his post, and maybe we mean different things, between us, for "slow" and "waiting as long as 30 hours [producing] nothing". Whatever the actual problem is, though, I assume the OP will have run appropriate diagnostics by the end of the day and will be able to narrow down the possibilities.
