Hello @arts.x , I don’t have a MacBook Pro M5, but I did some research and found a few things that might help resolve the issue. One of the most common solutions, and the one that worked for many users, is exactly what you already did: disabling the “UDP Messaging” plugin. In addition to that, you could also try disabling the Telemetry plugin, as some users reported improvements after doing so. Another thing you could try is adjusting the Editor Scalability Settings, as this has helped improve editor stability in some cases. > [@How to change graphics settings in engine](https://forums.unrealengine.com/t/how-to-change-graphics-settings-in-engine/2636022/2): > > Hi @d4griifer , I think this is what you’re looking for to change the graphics , select the option that says “Performance and scalability tools tied to this viewport” and then go to Viewport Scalability. There you can change the graphics for your engine,(this is in Unreal Engine 5.6), If you’re using an older version of Unreal, it appears at the top right under Settings , Engine Scalability Settings. Hope this helps! You could also try verifying the project or running it as an administrator. It might be worth a try, as it has helped in some cases. > **[How do I verify game files in the Epic Games Launcher? - Epic Games Store...](https://www.epicgames.com/help/c-32735058/c-36403860/a17813569)** > > Verifying the integrity of your game files will check the files on your computer to ensure they are not damaged or corrupted.

I mean I will be using my Mac only for Unreal Engine 5. I’m an Apple fan and I usually travel around my country. I knew that the Macbooks are much more efficient than PCs but I have some concerns about the Mac that may not be able to provide me a better experience than PC.
