I'm running OS X 10.6.8 and 10.10.2 on my MBP, and I'm confused by the way they interact...or, more precisely, fail to interact.
I can see and interact with Snowy from Yosemite, but not vice versa.
In Snowy, Finder can't see the Yosemite partition at all,
Disk Utility (1) sees it, but it's not recognized and is greyed out, and
Terminal (2) also sees, but doesn't recognize, it; the only action DU will allow as respects the volume is "Erase". (Terminal
(2) seems to be cool with my Recovery HD.)
In addition, DU > Get Info tells me that the volume is
not bootable while System Preferences > Startup Disk shows it as bootable but identifies it as OS X 10.7, rather than 10.10.2.
(1)Will somebody please explain why my Yosemite partition is both invisible, semi-visible, and Lion all at the same time?
Thanks.
