If your Mac doesn't support these OS versions, you're unfortunately not going to have any luck playing Roblox. Check whether there's a pending update and get your macOS system updated before attempting to update Roblox again.Īt the time of writing, Roblox requires at least macOS Yosemite, and Roblox Studio requires macOS El Capitan. The latest version of Roblox may depend on having a newer version of macOS than you currently have installed.
