Download the MacOS version of the game.
Follow the instructions on how to download and extract the MacOS version if you need help:
https://docs.google.com/document/d/1PQ4MwBLQaBUIcjs6-Hx1eflRQJe3GN63/edit?usp=sh... (for ARM-64 based Macs)
For INTEL-based macs (most pre mid-2020 devices).
Extract the Zip file, and drag the 'GROVE' app into your applications folder.
If a developer verification error appears when attempting to run the game, follow these steps:
1. Open 'System Preferences'
2. Go to 'Security and Privacy'
3. Go to the 'General' tab, then at the bottom (above the lock), grant an exception for the 'GROVE' app and click 'Open Anyway'
Once you've got the game running, come back to this website and download the Japanese Language Patch.
Once you've downloaded it, it should contain a folder called 'data'. Copy that folder... and past it into the Grove Game folder, here:
groverpgnsfw-macOS\GROVEv0.308MAC\GROVE.app\Contents\Resources\app.nw
If the computer asks if you want to replace existing files, say yes to all.
After you've done that, the game should be available to play on your MacBook in the Japanese language. Good luck!
