I just observed something that I'm having trouble believing.
To push Lion onto my daughter's laptop without waiting for yet another giant Lion download, I turned on sharing on my MBP, connected from my daughter's SnowLeopard MB, and dragged.
While the copy was in progress, the file name label on the desktop was 'MacOSX Lion <arabic word>'. Once the copy finished, the Arabic disappeared.
Is the evidence of a special easter egg, a feature, or my need for better medication?
