[Mac OS X] Using Memory Cards as a Boot Drive

Quick Note

On Intel based Macs, you can use USB thumb drives and SD cards as boot drives when you need to recover/re-install OS X. But they must be plugged into the BUILT-IN USB or SD card slots. The boot media will NOT work with a USB hub, memory card reader, or PCI interface. So, if you’ve been building a library of boot drives on SD cards for the Macbook Pro, then you’re SOL with desktop Macs that do not have a built-in SD card slot. You should move away from SD cards anyways since newer Macbooks do not come with built-in SD slots anymore.


The boot media must be formatted for “Mac Extended (Journaled)” and the boot partition must be “GUID” enabled.
