@fullblack said in MultiMC mac install:

It doesnt know where to install by itself (it wants to keep on installing to the normal minecraft folder instead of MMC (example: applications/multimc.app/data/instances/1.18)).
After you do install the patch it still only launches regular Minecraft. The fix i found to this is to add the EMC jar as a mod in MMC.

It's not possible to install to MultiMC on MacOS using the aristois installer, because MacOS treats MultiMC as an application and not as a folder. You must manually download some files for it to work. You can follow the instructions below:

Create a new instance for Aristois to run on. Do not install Fabric to the instance. Download this .zip file that contains all the required files: https://easyupload.io/fbt0xg Place the contents of this .zip directly into the instance folder (if done correctly, it should look like the image below)

Then, launch the instance making sure you use Java 17.
