how to shrink an os x intel dvd
Actually, this is not really specific for intel DVD's but it might work for any OS X DVD:
- Use Disk Utility to make a read-write image of the (dual layer) original Apple DVD, mine is called
AppleOSX_DVD.dmgand resides on the Desktop - In order to make it fit on a single layer DVD, remove stuff from the disk image that won't be used: The XCode Tools Folder, and all files in
/System/Installation/Packages(You can still put folders back onto the disk image after resizing the image file). - In the Terminal:
hdiutil resize -size 4.3g ~/Desktop/AppleOSX_DVD.dmg(online man page)
According to well informed resources on TUAW and onmac.net this works. Now if You receive the error: hdiutil: resize request is below minimum size allowed then You have not really deleted all the directories I indicated. Check back with hdiutil resize -limits ~/Desktop/AppleOSX_DVD.dmg and find the minimum size (first number, in 512b sectors) equal the current size (second number). And don't forget to empty the trash ;)
