HeyHeyBEEHeyHey

hey! I'm new to getting mods and stuff and after watching plenty of videos of people doing this with forge i eventually tried to do it myself, it has not been going so well. I believe you hit "files", "download", then "1.8" and so on... but it won't let me select 1.8. So is the website just not updated or am i doing it wrong. And I have a mac if that helps figure out the problem. Please right back soon, thank you!
