rbxfpsunlocker-osx is a Roblox FPS unlocker for macOS. This has been tested and works both on Intel-based Macs and on M1 Macs using Rosetta 2. However, this is an FPS unlocker and not an FPS booster and if your frame rate is the same or below 60 FPS, then your machine is not powerful enough to run Roblox at more than 60 FPS. Heavy usage of system resources may occur because of the higher frame rate.
