Frequently asked
What licence is I can't believe it's not Optifine! under?
Apache-2.0, as stated by the author on the platform we synced it from. Check the project's own page before redistributing or bundling it.
How do I install I can't believe it's not Optifine!?
Use a launcher that imports packs, such as Prism Launcher, the Modrinth App or the CurseForge app, and open the pack file with it. The launcher installs the right loader and mods for you; installing a pack's mods by hand is the error-prone way.
Where do I download I can't believe it's not Optifine! safely?
Start with the author's page on Modrinth, which is where the data here is synced from. MCReference does not host or repackage files. The download link goes to the source recorded for that release; verify the publisher, filename and checksum before running it.
Which Minecraft versions does I can't believe it's not Optifine! work on?
The author has not declared a supported version in the metadata we sync, so there is nothing here we can state as fact. Check the project's own page before installing it, and treat an old modpack with no declared version as untested on modern Minecraft.
