Terms of Use

Last updated 12 November 2026

Silica is a free, unofficial launcher and improved build of Minecraft: Java Edition Beta 1.7.3 for Apple Silicon. By using it you agree to these terms.

You need to own Minecraft

Silica works only with a copy of Minecraft: Java Edition that you own. You must sign in with the Microsoft account that owns it. Silica does not include Minecraft and does not let you play without owning it. You must not try to bypass the ownership check.

Not affiliated with Mojang or Microsoft

Silica is an independent project. It is not made, endorsed or supported by Mojang, Microsoft or any of their affiliates. Minecraft is a trademark of Mojang Synergies AB. Your use of Minecraft remains subject to the Minecraft End User License Agreement and the Microsoft Services Agreement.

No Mojang code or assets

Silica ships none of Mojang’s code or assets. On your Mac it downloads the game from Mojang’s own servers and prepares it locally for your personal use. Do not share or redistribute the prepared files.

Free and open source

Silica is free and has no charges or revenue. The source code will be released under an open-source licence at release, and that licence governs the source code. These terms cover use of the launcher app and this website.

Acceptable use

• Use only your own Microsoft account.
• Do not use Silica to access anyone else’s account, to cheat on servers that forbid it, or to break the law.
• Follow the rules of any multiplayer server you join.

Your worlds

Silica makes world backups and autosaves, but you are responsible for your own saves. Keep your own copies of worlds you care about.

No warranty

Silica is provided “as is” and “as available”, without warranties of any kind, express or implied, including fitness for a particular purpose. It is early software and may contain bugs.

Limit of liability

To the extent the law allows, the developer is not liable for any loss or damage arising from your use of Silica, including lost worlds or data, or problems with your Microsoft or Minecraft account.

Changes and contact

These terms may change as Silica develops; the date above changes with them. Questions: open an issue at github.com/undrwtrsprite/silica/issues.
