I have came to an issue on my Minecraft launcher for some reason. Whenever I try to launch 1.17 on the launcher, it says "downloading" and displays that for a long time. I don't really know what to do. I tried installing optifine along with the version download and it gives me the same issue. Please take a look at the image! The image stays like that and the numbers will never move. Please help!

Edit: I am on a MacOS Sierra by the way.

Another edit: The launcher works for previous versions.
