I am trying to use Roblox Studio on Mac OS X 10.11.6 El Capitan. When I launch Studio, I can navigate the file menu or the various place-opening tabs just fine. Once I open any place (including a blank baseplate) Studio takes 30 seconds to a minute to respond to clicks in the viewport, ribbon bar, etc. IF it responds at all—a lot of clicks are completely lost.
I do not get a rainbow wheel, and the OS seems to think it’s still running fine, but Studio is completely unusable because of the lack of response.
If a place is open, the close/minimize/fullscreen buttons also take a significant time to respond, if at all.
If Studio is the focused application, it ignores any click on the “RobloxStudio” option in the menu bar, and interestingly, it also ignores clicks on the Apple menu (), however, I can click on icons in the top-right of the menu bar (volume, WiFi, Bluetooth, etc.) and they respond immediately. If Studio is not the focused application, the Apple menu responds immediately.
