How to Optimize Minecraft 1.19 for M1

⚠️ ⚠️ IMPORTANT: PolyMC, the project that ManyMC is based off, has been taken over by a toxic and possibly (although no proof exists) malicious individual. Please do not follow this tutorial. Do NOT use PolyMC. We will be producing an article shortly about how to do this WITHOUT PolyMC. Please stay tuned and join the discord (https://discord.gg/infotoast). We are working on a way to fix this problem, but for the time being, DO NOT USE MANYMC. We have kept this article for historical sake, follow at your own risk.

This is the fourth part of the series I’ve written on optimizing Minecraft for M1. Now that Minecraft 1.19 has been released, I will be writing on how to optimize Minecraft 1.19 for M1.

Thankfully, new tooling has been released by now that makes optimizing Minecraft for M1 much easier. It’s an app called “ManyMC”. It’s basically MultiMC like we used previously, except all the scripts and things have been automatically bundled.

If you go to the PolyMC GitHub, they will recommend using Homebrew to install it. DO NOT use Homebrew. The reason is available here: Homebrew is a Major Security Flaw — Install MacPorts Instead.

Step 1: Installing A Native Java 17 for optimizing Minecraft 1.19 on M1

Minecraft 1.17 requires Java 16. Minecraft 1.18 and 1.19 require Java 17, the latest LTS version of Java. As we have done previously, we will be using Zulu JRE rather than Oracle’s JRE, even though Oracle’s JRE is now available for M1 Mac. Zulu is much faster, therefore we will use Zulu to optimize Minecraft 1.19 for M1. Click on this link and download the latest version of Zulu JRE for arm macOS: https://www.azul.com/downloads/?version=java-17-lts&os=macos&architecture=arm-64-bit&package=jdk. Once you have clicked there, download as a .dmg:

Download Zulu as a .dmg

Once you have downloaded the .dmg, open it and see that it has a .pkg file. Double click on the .pkg file:

Install Azul JDK to optimize Minecraft 1.19 for M1
Double-Click on the .pkg file

Go through the wizard. It should be simple to install. Once it is installed, it is time to install ManyMC.

Step 2: Install ManyMC

Click the button below to download ManyMC:

Once the ManyMC zip is downloaded in order to optimize Minecraft 1.19 for M1, double-click on it, and you should get an application. Double-click on the application. It will tell you it comes from an unidentified developer. Open your System Preferences > Security & Privacy > Open Anyway

You will need to type your password or scan your fingerprint after pressing “Open Anyway”

This will launch ManyMC. Select your language. Then, at the next screen, select the Zulu JRE you just installed:

It may not look exactly like this, as I use MacPorts to install JREs, and also mine is a JDK and not a JRE.

Press “Finish”. Now, you must log into your Minecraft account. Go up to Profiles > Manage Accounts on the top right:

Profiles > Manage Accounts

I’m fairly sure by now that there are no longer any Mojang accounts in existence, or at least ones that are not locked, so go ahead and click “Add Microsoft” at the top right.

Next, open https://microsoft.com/link. Place the code provided by the app there:

Type the code provided by ManyMC

Now, log into your Microsoft account.

Step 3: Creating a Minecraft 1.19 Instance Optimized for M1

Finally, now that you are logged into Minecraft, you will want to create an instance. Press Add Instance at the top. You will see the following menu:

Set up the instance to optimize Minecraft for M1
PolyMC Instance Creation Menu

At this point, it’s up to you. Play how you want to play. You’ve optimized Minecraft 1.19 for M1! Use whatever mods you want to use. I may create a tutorial on how to play with some common mods such as OptiFine in the near future, so be on the lookout for that. But, for now, keep in tune.
