Piker Alpha Support (upgrading Mac OS X 10.7 to Mac OS X > 10.9)

[mearvk]

1. Can this work with 10.9 Mavericks or is it tied more strictly to OS 10.11 El Capitan?

2. Will UEFI swap disable OS X from working on previous versions? I.E. will OS X 10.7 now not work with Piker UEFI update?

3. Can 10.7 be dual booted with 10.8+?

4. X 1900XT graphics cards will they be able to run OS X 10.11 El Capitan or not?

Thanks.
