Help! Concrete ceiling crack!

I recently bought a condo. The building was built in the 70's and had popcorn ceilings. During remodeling I scrapped it off and removed some drywall. I then noticed a crack in the ceiling. It's pretty thin, and pretty straight, but I'm worried that when I go to sell the unit in the future, a home inspector will have issues with it. I just want to determine if it is cosmetic or if there is structural damage that I need to fix. It's near the middle of the ceiling and I believe it runs the length of ceiling. I'm not sure though because after I scrapped the popcorn, I painted. It wasn't until after I removed some drywall that I discovered the crack.
Could it just be a seem between two pieces of precast slabs?
Also, I believe it has been there since the building was built. This is because there was some white plaster or mortar of some kind covering some of the crack (as well as other spots) in the ceiling. So that would mean that the plaster was placed there before the popcorn was laid down, unless the popcorn had been removed and then reinstalled at some point. But I find that unlikely since removing popcorn is such a pain.

I have pictures but not sure how to post. Doing this from my phone...

Thx!

The odds are it's just cosmetic. I would think if it's structural that the association would be responsible for making the repair.

 

Yes. Many apartments/condo's are built using precast slabs for fire and hurricane protection. Some cases they do not even cover it with drywall and just texture and paint the slabs themselves.
