Hi everybody,
My name is Enrique Diaz (Diazruanova) and I am new to this forum
I would like to say that so far, booting from a USB external disk by creating a SandBox partition, has been a straightforward operation so far!
No problems whatsoever besides a Restart time much longer than that from booting with the original internal drive on my iMac Intel Core 2.
Also i have NOT noticed a perceived delay in opening and working with apps compared to booting with the Mac HD, but I have been working like this just a few hours since the first SandBox restart.
I will post here again if I encounter something odd.
