How to Change Roblox FPS on Mac Using File Explorer (Finder)
Roblox on Mac runs at a default frame rate cap that doesn't always match your display's capability or your hardware's potential. If you're seeing choppy gameplay or want smoother motion, adjusting the FPS cap through Roblox's client settings file is a well-known method — and on Mac, that means navigating through Finder (Apple's equivalent of Windows File Explorer) to locate and edit a specific configuration file.
Here's what you need to know about how it works, what affects your results, and why the same steps can produce very different outcomes depending on your setup.
What Controls Roblox FPS on Mac?
Roblox uses an internal frame rate cap that limits how many frames per second the client renders. By default, this cap is set to 60 FPS. For many users on standard 60Hz displays, this is fine — but if you have a high-refresh-rate monitor (120Hz, 144Hz, or higher), your display can handle more, and Roblox won't take advantage of it unless you intervene.
The FPS cap isn't buried in Roblox's in-game settings menu. Instead, it's controlled through a ClientAppSettings.json file stored locally on your Mac. Editing this file tells the Roblox client to raise or remove the frame rate ceiling.

- In the menu bar, click Go → Go to Folder (or press Shift + Command + G).
- Type or paste the following path:
- Look for a file named ClientAppSettings.json. If it doesn't exist, you can create it using a plain text editor (like TextEdit set to plain text mode, or a code editor like VS Code).
- Open the file and add or modify the following entry:
