Yes it does.
Parallels changed my host name to the host name of the guest OS.
I can't 'just change it back' System preferences reports the correct hostname, and terminal reports the wrong one.
iMac (Sept 2008)
Core 2 2.8ghz
4 gig ram
Parallels 4.0, but its uninstalled. Or at least i ran the uninstaller pkg.
I want my host name (and by extension, my computer) back. Please help!
