Hello guys,
I just installed my old Macbook Pro and it asks for Mac mini password.

The thing is, that the SSD comes from mac mini, but OS was re-installed. Why it still thinks that I have mac mini, when I clearly have Macbook Pro?

When you say the OS was reinstalled, did you reformat the drive then install, or did you do an in-place re-install?

If you re-install from the recovery partition without reformatting the drive, it leaves user spaces on the disk intact (/Applications, /Users, and libraries where settings are kept), and only writes over the "generic" OS files. In this case, the Mac mini user account and password would be intact, as would applications and settings.

That's a normal part of iCloud activation, I think. It's asking you to authenticate yourself by providing a trusted password.

"The thing is, that the SSD comes from mac mini, but OS was re-installed. Why it still thinks that I have mac mini, when I clearly have Macbook Pro?"

Let's get a few things straight here.

First -- You took your old drive out of the Mini, and then installed it into a MacBook Pro?
Is this correct?

OK, if you did that (nothing wrong with doing so), then...
... did you choose to "re-install the OS" on the MacBook Pro (with the old Mini drive)?
Is this correct?

If all the above is correct, here's why the old "Mini password" was retained:

When you choose to "re-install the OS", the installer DOESN'T TOUCH your personal information in your home (user) folder.
All it does is upgrade or replace the OS files (themselves).

Your "prior personal information" is left intact.

So... that's why you still retain "the old Mini password" on the MacBook Pro.
The OS upgrade didn't touch it.
