Running 12.10 in a house with several macs, was connected to mac mini
through wifi router and noticed that performance dropped considerably
after being connected for a while (also kept having to reconnect to the
folders, and then kept timing out rather than letting me unmount one of
the shares).
Public bug reported:
I remembered several years ago trying a Korean install, but I remember
you had to hack it to get input to work.
I run an English install of Quantal (AMD64) so I tried a korean
installation in virtualbox, and realised that there is still no korean
input available on default
