Remember what it was like to install a new version of OS X? That meant standing in line at the nearby Apple Store, forking over money, and rushing home with the DVD to begin the installation process. Those days are gone.
But I Want An Installer Disk
Today, new versions of OS X are installed from a download on the Mac App Store. There’s not waiting in line and no price tag. OS X Yosemite (as was Mavericks) is free.
There are a few situations where you might prefer the old fashioned way– installing OS X from a bootable disk or USB disk.
How? All we get these days is a humongous 5-gigabyte installer file which won’t easily boot itself without human intervention.
Here’s the intervention.
DiskMaker X (which was once called Lion DiskMaker, back when OS X started coming to us as a download (and which needs an updated logo design), is a free Mac utility which lets you create an OS X installer disk.
The process couldn’t be much easier, either. Fire up DiskMaker X, follow the prompts, and you get what Apple doesn’t want us to have.
That’s about it.
DiskMaker X is smart enough to find the downloaded version of whatever OS X version you want to use to create a bootable installer, and will list it in the window. DiskMaker X works better with a downloaded version of OS X, so I recommend starting there first.
For those Mac users interested in installing OS X Whatever onto a USB flash or thumb drive, I recommend at least 8GBs to ensure enough space. Rest assured, there are possible problems as not all Macs are created equal, but I’ve used it on OS X Mountain Lion, OS X Mavericks, and now OS X Yosemite with few notable hiccups.
Besides, it does what Apple doesn’t really want Mac users to do despite the fact that some of us need a bootable installer disk, and it’s free.
