Does anybody have a Macbook Pro with this version of the public beta? My Macbook Pro will barely work with this. I know they say that things happen on betas, but to the point where you can't use it barely? What's strange is it is fine on my iMac but not my Mac. I just want to see if anybody else has any issues. I'm going to give up on trying on my Mac and revert to Lion and then get back on El Capitan, which is possible but you have to erase your profile first in disk utility.
