For anyone interested, it's quite simple to get this game working on Mac! I did it, and it's pretty straightforward!
1. Go to
this thread and download the Mac version he has listed (as of today it's 1.6.2 for MV).
2. Extract the file and you'll see a folder with a file called 'Game.'
3. Rename that Game file 'Daily Lives of my Countryside' or whatever you want, then right-click, Show Package Contents.
4. Navigate to Contents > Resources > app.nw. You'll see a single file titled Package.json.
5. If you haven't already, download the latest Windows version of 'DLomC' and unzip the RAR file (I use The Unarchiver, but you can use whatever).
6. In the extracted files, navigate to Daily Lives... > www.
7. Select everything in that 'www' folder, and copy it to the 'app.nw' folder (overwriting the Package.json file).
And that's it. Open up the game file you renamed and it should run normally.
As far as I know, this can be done with any RPG Maker MV game as well. I did with Town of Passion and it also works perfectly. I'm running OS X 10.13.6 currently, but I'd imagine it'll work for higher versions as well.
Happy gaming!
