Hi, i intend to purchase the Sandisk ultra flair flashdrive but before i purchase i tried to download the SecureAccess on the Macbook just to see if it works. Unfortunately, after i downloaded it and open the installation window, i clicked “Continue” and selected “Mac HD” but it wrote that it can’t be downloaded on this mac. There’s no other selection. I can’t see any No Name or anything. I’m a new macbook user so i’m not really super familiar.
