OpenAFS.org have NOT YET RELEASED any AFS OpenAFS client installer built for OSX 10.10. The 1.6.6 release is known to have problems with 10.10. The OpenAFS client integrates with the operating system at a sufficiently low level that it is very unlikely to work with a different major release of OSX. If working directly with RStor is a 'must-have', we recommend NOT upgrading to Yosemite yet. -- Richard Brittain, Research Computing Group, IT Services, 37 Dewey Field Road, HB6219 Dartmouth College, Hanover NH 03755 [log in to unmask] 6-2085
