I have el captain and want an alternative boot drive for this older laptop
I have an older macbook pro with osx installed. My present internal hard drive is loosing the boot sectors and several times I have had to use the disk utility to repair the boot.
I have a WD portable that is formatted for MAC. How can I get OS X boot installed on the WD drive?
MacBook Pro (17-inch 2.4 GHz), OS X El Capitan (10.11.3)
