Install Prism Launcher
Prism Launcher is a free, open-source Minecraft launcher that handles all the mod stuff for you. Pick your OS below and you'll be done in a couple of minutes.
What even is Prism Launcher?
Prism Launcher is a community-maintained Minecraft launcher. It lets you create separate "instances" of Minecraft, each with their own mods and settings, and it can import modpacks from a URL in one click. It's the easiest way to get set up for the server.
Works on Windows, macOS, and Linux. Grab it for your platform, then head to the Setup page to import the modpack.
Run the installer
Double-click the .exe and click through. Defaults are fine.
Java: Pick Java 17 or higher. Prism can download it for you on first launch if you don't have it.
Launch and log in
Open Prism, click "Add Account", sign in with your Microsoft / Minecraft account, and you're good.
Windows Defender SmartScreen might pop up. Click "More info" then "Run anyway". It's legit open-source software.
Download the app
Go to prismlauncher.org/download and grab the macOS .dmg. Separate builds for Intel and Apple Silicon (M1/M2/M3).
Not sure which? Apple menu > "About This Mac". Says "Apple M-something" under Chip = ARM build. Says "Intel" = Intel build.
Install it
Open the .dmg and drag Prism into Applications. Standard Mac stuff.
First launch
macOS will warn you it was downloaded from the internet. Click "Open". If Gatekeeper blocks it, go to System Settings > Privacy & Security and click "Open Anyway".
Select Java and log in
Pick Java 17+ (it can download one). Sign in with your Microsoft / Minecraft account.
Install Prism Launcher
Pick your poison:
Flatpak (works on anything)
flatpak install flathub org.prismlauncher.PrismLauncher Arch (AUR)
yay -S prismlauncher Debian / Ubuntu
Grab the .deb from prismlauncher.org/download and:
sudo dpkg -i prismlauncher_*.deb
sudo apt-get install -f Fedora
sudo dnf install prismlauncher Launch and log in
Open Prism, pick Java 17+, sign in with your Microsoft / Minecraft account.
Fix inotify limits (you have to do this)
This pack has loads of mods that watch config files. Linux's default file watcher limit is too low and the game will crash on startup without this. Run it once:
echo "fs.inotify.max_user_instances=512" | sudo tee -a /etc/sysctl.d/99-minecraft.conf
echo "fs.inotify.max_user_watches=524288" | sudo tee -a /etc/sysctl.d/99-minecraft.conf
sudo sysctl --system Not optional. Without it you'll get User limit of inotify instances reached and the game dies. Run it once, it sticks across reboots.
Next up: Import the Modpack
Prism's installed and you're logged in. Head to Setup to import the pack and get connected.
