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!
I've got Optifine working while using the official launcher method. Fairly straightforward. Follow this guide: https://github.com/jacyhung/m1-native-minecraft-optifine
In short: if you've already followed everything in THIS gist, and have named your version
<version>-arm64, then you can literally download the optifine folder from my repo and add that into your versions list, then add it as a new installation source in your launcher.If you want to tackle it yourself,
~/Library/Application Support/minecraft/versions. Rename the newly created Optifine folder and append-arm64to the folder name.-arm64to the end of both file names..jsonfile."id": "1.18.1-OptiFine_HD_U_H4",line to"id": "1.18.1-OptiFine_HD_U_H4-arm64",."inheritsFrom": "<version>",line to"inheritsFrom": "<version>-arm64",.
