DVD-less Snow Leopard installation on older Mac
Reader Steven Harris is trying to do the right thing by his family, but technical barriers prevent it. He writes:
Over the holidays I took your advice to give the gift of tech support by offering my services to my sister. She has an older MacBook Pro running Leopard and wants to upgrade to Snow Leopard (she needs Rosetta to run older PowerPC software). Three problems: Her DVD drive is broken, I have a MacBook Air without a DVD drive, and I have only a disk image of Snow Leopard. When I place that disk image on her MacBook, mount it, and try to run the Snow Leopard installer, I’m told I need to burn it to disc, which isn’t an option. What do I do?
I’m afraid you’re another casualty of the who-needs-media-drives-any-more campaign. While it’s true that SuperDrives are becoming less necessary for many people, there are occasions when a built-in drive is a godsend. This is one such case. Fortunately, there’s a workaround more convenient that purchasing an external DVD drive and a 5-pack of double-sided writeable DVD media. It goes like this:
Dig up a 16GB-or-larger USB key drive. Jack it into your MacBook Air and launch Disk Utility (found in /Applications/Utilities). In Disk Utility select the key drive, click on the Erase tab, and from the Format pop-up menu choose Mac OS Extended (Journaled). Click Erase to format the key drive.To read this article in full or to leave a comment, please click here
