Resource Pack Zipping

I have run in to many tutorials, but none have seemed to work for me.
I have made a resource pack, (3D on Mac) but it zips with the structure folder and not the assets, pack.mcmeta, and pack.png. This is a problem since I need it for my server. Can anybody help me with the zipping process without the "structure folder?" The custom pack I made works unzipped in the resource pack folder. Any help is appreciated!
