Deployment Solution 7.x
Mac OS X 10.10 is being worked on and an early support statement identifying what works with the current shipping product will be available shortly (Nov 2014).
Full support will be available in an upcoming hotfix.
Deployment Solution 6.9
For Deployment Solution 6.9 customers there is an agent build available for testing that has most functionality working for OS X 10.10. Please send a private message to me (David_Evans) with evidence of your current maintenance entitlement and I will get you the agent for testing. Due to legal reasons the agent cannot be distributed to customers without current maintenance.
Ghost Solution Suite
Support will be added with the completely redeveloped GSS 3.0 that is coming early next year.
Note: while we cannot respond to all comments directly or guarantee that support will be added we do read all comments and use them to help drive our roadmap.
