Missing Fracture Mode on Mac

Hello There. My name is Lorenzo and I’m new to Unreal Engine. I’m using UE 4.26 and I’d like to create a short movie. I’m looking to destroy some buildings/objects but I’m missing the fracture mode under the dropdown menu of modes. I enabled all the chaos plugins but still that mode is missing. I looked for tutorials/videos but could not find anything for this version of UE.
Can anyone please help?
I’m working on a MacBook Pro.
Thanks in advance
