Some notes about Yosemite upgrade
- the 5.17GB Install Yosemite dmg file should be cached completely with an xml file
- Casper suite must be upgraded, it didnt work initially for us for 9.31 so we upgraded to 10.62 and its working now
one point I would need assistance with is that what happens if the macbook is not connected with power cable or not more than 50% charged, this might turn up as a reason Failed to Upgrade, not sure yet.
