The Super-Simple Guide to Full Screen Undertale on Mac
Alright, enough convincing! Let's get down to business. Here's how to get Undertale running in full screen on your Mac. It's easier than making instant ramen, I promise!
Method 1: The Built-In Trick (If It Works!)
Undertale has a built-in full-screen function, but sometimes it can be a little... temperamental. Here's how to try it:
- Start the Game: Launch Undertale like you normally would.
- Press Command + F: This is the standard Mac shortcut for toggling full screen. Give it a shot!
Did it work? Awesome! You're done! If not, don't worry. We have other tricks up our sleeve.

Method 2: The Configuration File Edit (A Little More Advanced, But Don't Panic!)
This method involves tweaking a file that Undertale uses to store its settings. It sounds scary, but trust me, it's not rocket science. Think of it like adjusting the volume on your stereo – a little fiddling can make a big difference.
- Find the Undertale Configuration File: This is the trickiest part, but I'll guide you. Open Finder.
- Go to the Game's Folder: In Finder, press Shift + Command + G. This will open a "Go to Folder" dialog box.
- Enter the Path: Paste this into the dialog box: ~/Library/Application Support/com.tobyfox.undertale and click "Go".
- Locate "options.ini": You should see a file named "options.ini". This is the file we need to edit.
- Open with TextEdit: Right-click (or Control-click) on "options.ini" and select "Open With" -> "TextEdit".
- Edit the Values: Look for these two lines in the file:
- fullscreen=0
- borderless=0
- Change the Values: Change both lines to the following:
- fullscreen=1
- borderless=1
- Save the File: Press Command + S to save the changes to "options.ini".
- Restart Undertale: Close Undertale completely and then relaunch it.
Ta-da! Hopefully, Undertale should now be running in glorious full screen mode. If it's still not working, double-check that you saved the "options.ini" file correctly and that you restarted the game.
Method 3: Using a Third-Party App (For the Tech-Savvy)
If you're comfortable with using third-party apps, you can try a program like "Windowed Borderless Gaming." These apps essentially force any windowed application into a borderless full-screen mode.

Disclaimer: I'm not officially recommending any specific app, as I haven't tested them all extensively. Do your research and make sure you download from a reputable source. But if you're familiar with these types of tools, it can be a quick and easy solution.
Troubleshooting Tips
Sometimes, things don't go as planned. Here are a few common issues and how to troubleshoot them:
* Game Looks Stretched or Distorted: This can happen if the game's resolution doesn't match your monitor's resolution. You might need to adjust the resolution settings in the "options.ini" file (look for lines like "screenwidth" and "screenheight").* Full Screen Doesn't Fill the Entire Screen: This could be due to your Mac's display settings. Check your system preferences to make sure scaling is set correctly.
If all else fails, don't hesitate to search online for more specific solutions. There are tons of Undertale fans out there who have probably encountered the same problem and found a fix.
Enjoy the Full Experience!
Now that you've conquered the full-screen challenge, it's time to dive into Undertale and experience it the way it was meant to be played. Get ready to laugh, cry, and maybe even question your life choices (in a good way, of course!). Remember, every pixel tells a story, and now you can see them all!
So grab your favorite snack, dim the lights, and prepare for an unforgettable journey through the Underground. And most importantly, have fun! You deserve it.
