Need help fixing Virtual box

So awhile ago I set up a VM of Ubuntu, just to try it out. Then for next semester for one of my classes I need to use MacOS so I was going to make a VM of it to make it simple. I eventually got the iso of MacOS and went to make the machine. Now I am getting this error on both of the machines when I try and start them up. Any ideas? picture of error

Edit: I turned off the setting that is said was off but was really on and now it's working
