Honestly,
I don't believe this one will be the release build.
I mean don't take me wrong, this thing is fast and stable. No kernel panics or slowdowns for that matter.
I did a clean install and the issues I'm having are all related to multi touch.
First bug is related to three finger drag. Every time I restart it deselects that option.
Second bug is related to four finger app expose. Unless I am doing something wrong, the first time I use it, it shows me all the apps open, plus a small icon of the apps that I have minimized. When I try to do it for the second time, it kind of put the app I'm using in evidence.
One thing that I noticed is that when you lock your screen and you have to type your password to go back to the desktop, the new lock screen is kind of ugly to be honest. It does not feel right. I know this is something minor, but come on, we are talking about MacOS which is known to be a good looking piece of software.
Taking those few grips aside, definitely is going to be day-one buying.
