@wilsmith1924 Are you playing the 64-bit version of Sims 3 or the old 32-bit version? (Or are you playing through Windows?) Do you have more than one entry for Late Night in your list of packs, and if so, does another entry have a Download button you can try instead? I have multiple copies of each of my packs, but only one per pack has a working Download button.

@wilsmith1924 Again, do you have more than one entry for Late Night in your list of packs, and does another copy have a Download button that does work? Are you in fact clicking on the 64-bit version of Sims 3 in your library? If you click on the 32-bit version and then click Download on the Late Night listing within, the Download button won't work. You specifically have to go through the 64-bit entry.

@wilsmith1924 Try running the Origin reset tool for macOS:

Repair your game afterwards: open your Origin game library, right-click on the Sims 3 icon, and select Repair.
If that doesn't help, enable automatic game updates in Origin: hover over your username, select Applicaiton Settings, and under Application (the first header), scroll down to Client update and enable auto game updates. Then quit, reset Origin, and see whether Late Night starts downloading automatically. If it doesn't, repair the game, quit Origin, and reopen it.
If auto game update are already enabled, disable them, reset Origin, then try the process above.
