Hey guys, so I have a 2012 MacBook Pro and upgraded the ram to 16 gigs as well as purchased two SSDs to install. However, when I tried to remove the HDD and replace it with an SSD, I had a lot of problems, so I just settled for putting in one of the SSDs and using a secondary HDD caddy to put it in. Now i have it in, but I am unable to partition it in the Disk Utility menu. Can anyone please shed a little light on how I should go about making this expensive addition usable? I appreciate any and all help.
