In the instructions below, replace <version> with the official version name. For example, 1.18-pre6 or 1.18.1
- Run
<version>in the official Minecraft Launcher, then quit both the game and the launcher. - Open
~/Library/Application Support/minecraft/versions. - Duplicate the folder
<version>and name the new one<version>-arm64. - Open that new folder up and delete
<version>.json. Download this<version>-arm64.jsonfile and put it in this new folder. - Rename the file
<version>.jarto<version>-arm64.jar. - Download a Java 17 JRE for Apple Silicon. Recommend the latest Java 17 LTS JRE. You can download the zip and store it anywhere, but I recommend the installer package. This will install it to
/Library/Java/JavaVirtualMachinesfor you. - Open Minecraft Launcher and create a new profile. Choose
<version>-arm64from the list. - Expand the profile options and choose to set a Java executable. If you installed it in
/Library/Java/JavaVirtualMachinesgo there, then open up your JRE > Contents > Home > bin and selectjava.
Should be all set!
You can download the 1.18.2.json file through M1Craft app. You have to launch a 1.18.2 session first, then from the main app window, you can export it from the finder bar. I did not include them in my repository as it is not my work, it is @ezfe’s!
