Issues with Twitch Launcher loading mods (Mac)

Prior to this morning this was not an issue at all, so I am not sure what changed. I would like to state that in the hopes to fix this problem I have already restarted, and reset my computer multiple times. Basically the problem is, whenever I launch a modpack from the twitch launcher, I get the image displayed of loading versions, and a grayed out loading... section. To this, I googled multiple ways to fix this problem. The one main solution I found was to download the 1.6.93 launcher and replace that with the launcher already in the minecraft folder within the twitch launcher. Cool, I did that. However, whenever I tried launching a modpack using the new launcher, I was able to click play, but was led to the game output screen as displayed in another image every single time. Please help!
