When I enter Time Machine and the dates appear on the right hand edge of my screen, some dates are purple in colour and some are grey/white. I have not been able to figure out what the difference is between them. Anyone have an answer for me? I have attached a pic..
Thanks,
Thom
Note: Dates in pink indicate the data resides on your Time Machine backup device. Dates in white indicate the data resides on your Mac. In OS X Mountain Lion and Lion, portable Macs have the feature of local snapshots. See this article for details.
