4 years ago I'm unable to reproduce this issue. Please try whitelisting the twitch launcher from your anti virus program.
Otherwise you will have to contact the CurseForge support here: https://twitchpartnerships.force.com/curseforge/s/contactsupport
When I try to download this modpack in twitch on a mac, this message pops up: "Unable to get Addon: Galactic Science (232015) - File ID: 2761972"
Could someone help me with this issue or tell me another way to play this pack?
