Hello. I have the same issue with 2015 MacBook Pro 13'' Retina with 8 gb of RAM. It's download well, but when it get started preparing for install, it stopped without problems of cpu, ram or disk space. Appears a notification that says that will be installed on my computer this night , but I think that it will not happen... Could you help us with the issue?
Another question that I have is that I have installed public beta 11.0 and appears as option on preferences, install beta 5 11.0. Is it a good way for doing the update? How can we fix it?
