    So after I updated to 10.12.2, I only turned off my mid-2012 13 inch MacBook Pro twice (I rarely turn my MacBook Pro off). I turned it off because I had to make a bus trip. But after the trip I'm always stuck in boot loading screen after I entered my password. It usually stops at around 75%.

    I tried resetting the pram, starting is safe mode, and did a first aid via disk repair, but nothing works so far. I don't think it's a hardware issue because my windows 10 bootcamp partition boots just fine.

    Do you guys think I should reinstall Sierra? Or is there any other way?
    Thank you

    P.s. I know my computer is old, and it has been used extensively. But before this problem occurred, I've never had any performance issue whatsoever.. (Including with 10.12.2)

    Try a verbose boot. That may shed light on why it's freezing. Alas, I don't recall how, exactly, you do this.

    Verbose mode = Command + V after you hear the chime.

    Thank you guys for the answers. Yep, after a little bit of browsing, I found an article that explains how to do it and what it actually does.

    I thought this might be the solution. I tried it. Unfortunately, after the texts finished running I'm back to the loading screen (with the progress bar) and this time there's no progress going.

    Given what you've already tried I recommend a Erase and reinstall of macOS. Please be aware this is a data destructive task.
