This week Apple released OS X 10.9 Mavericks for free through the App Store. Even though downloading from the App Store works great for updating, I also want to be able to perform a clean install and create VMs running OS X 10.9 Mavericks. I also don’t want to download the 5+GB update file every time I upgrade a system.
Unfortunately Apple doesn’t provide an ISO download or a tool to create an ISO or bootable USB drive. There are however many people with similar needs that provide information on how to create both. The downside of these methods though, is that you need to have a working OS X system to be able to use them.
