Minecraft on Apple Silicon (v2 - 1.17 & Microsoft authentication)

In this gist, you can find the steps to run Minecraft 1.17 natively on Apple Silicon (AS), without needing Rosetta 2 translation of the dependencies (mainly LWJGL and related libraries).

While it's possible to use a launcher like MultiMC to have a prettier way to run the game on AS, it requires installing even more dependencies (like QT) which take time and are difficult to distribute. Therefore, I've put together a command line-based launcher tool using a couple shell & Python scripts.

To get up and running quickly, follow the steps below. Otherwise, for more detail, watch my YouTube videos: old, new.

Download my package

To begin, download the Minecraft on Apple Silicon package I've already put together, containing some pre-compiled core dependencies like LWJGL and a convenient set of setup & launcher scripts. Unzip the file, and navigate to it in your terminal. Then follow the next steps.

Download NPM modules required for Microsoft authentication

You only need to run this if you plan on using a Microsoft account for authentication

npm install --global @xboxreplay/xboxlive-auth request

Download Minecraft client & client libraries

cd libraries
sh download.sh
cd ..

Download Minecraft assets

python3 downloadassets.py

Run Minecraft! (Microsoft account)

Note: Replace [email protected] and password with your actual username & password for Minecraft, but keep them enclosed in single quotes. This data is only used to communicate with Mojang's authentication servers and is never stored. The file containing your authtoken is deleted after the game launches.

export MCEMAIL='[email protected]'
export MCPASSWORD='password'

sh launch.sh

Run Minecraft! (Mojang account)

Note: Replace [email protected] and password with your actual username & password for Minecraft, but keep them enclosed in single quotes. This data is only used to communicate with Mojang's authentication servers and is never stored. The file containing your authtoken is deleted after the game launches.

sh mojang_launch.sh '[email protected]' 'password'

It took me some extra steps to get it to work. I had to select "Allow macOS to run 'lwgjl-......dylib' ten zillion times in Security settings in System Preferences) while I attempted to launch it over and over until it granted permission to everything in 'lwjglnatives'.

But when I launch it... the best way to describe it is that it's really slow. It takes several seconds to detect mouseovers or UI button clicks. It would not accept keyboard input in the Multiplayer Servers menu. I did not even try actually starting a game because it was clear from the tremendously slow performance in the menu UI that it would not work out well for me.

How can I fix this?

I tried restarting my computer and reinstalling the npm modules and Minecraft assets, but this did not fix it.

After completing all the steps i ran the sh launch.sh line and was given this

Traceback (most recent call last):
File "getuuid.py", line 15, in
username = sys.argv[1]
IndexError: list index out of range
Traceback (most recent call last):
File "getusername.py", line 15, in
username = sys.argv[1]
IndexError: list index out of range
Traceback (most recent call last):
File "getauthtoken.py", line 15, in
username = sys.argv[1]
IndexError: list index out of range

Does anyone have a solution. I have verified that my email and password are the correct ones i use for the microsoft login.

when running the download assets I get this

/Users/wadeglover/Downloads/MCAppleSilicon 2 copy/downloadassets.py: line 1: import: command not found
/Users/wadeglover/Downloads/MCAppleSilicon 2 copy/downloadassets.py: line 2: import: command not found

BTW, this package uses Log4j 2.14.1, so it's susceptible to the remote code execution exploit - any chance of a notice or update? @tanmayb123

You could technically just download the newer 2.16.0 jar files, and replace the 2.14.1 jar files with the new ones in the folders and the launch arguments.

There is a new Application for macOS which does all the hard work for you, and all you need to do is click play. You can find the repository here and the installation steps here.
