Object Snapping

I’m relatively new to Rhino for Mac and am having issues with my snapping tool. One object will not snap to another object unless the object that it needs to be snapped to is selected (if that makes sense). I’ve checked all of my snapping options but nothing seems to work. I’m not sure if there is a setting that needs to be changed but any help would be appreciated!

Hi Ally -

It sounds like the Options -> Modeling Aids -> Object snaps -> Only snap to selected objects option is checked?

You saved me! Thank you so much.
