Anyone know how to avoid the hours-long double download?
Apple says just do multiple downloads- on DSL this is about 3 hours. Anyone know how to boot installer into more than one CPU?
Download the installer; right after the download is done, dismiss the installer and find it in the Applications folder. Copy it to a safe place/external hard drive. Then go ahead and install - the installer will self destruct when finished. Copy the installer to the other machine and install (keep a copy of it in a safe place).
