For one reason or another, I cannot download and run this latest beta on my sandboxes (unsupported macs). I have a couple macs that is supported but will not install since I consider them not to be sandboxes. My question for users here that was able (and willing) to install 10.14.1 beta 1 on their Mojave unsupported or supported mac, any issues on your use/testing? I'm particularly interested on new features such as Group Facetime? Or your overall observations for the beta 1? ~Mahalo!~ P.S. I did ask the same questions on the unsupported thread, but have not had any responses yet. Additional question ~ installed or upgraded to Xcode 10.1 beta? Any issues with this as well?
