Hi, I apologize in advance if this has been answered in totality already, but much of this is new territory for me and maybe I'm just a bit dense. Despite reading a few dozen postings here and elsewhere, I'm still trying to put the whole thing together in my head conceptually. Backstory is that I was finally able to get a 2012 2.3ghz i7 refurb off the Apple site. I'll be upgrading to 16gb of memory and adding a 256gb SSD to run externally via a USB3/SATA dock. So far so good. What I'm unclear about are the steps in setting up the drives (i.e. splitting, and maintaining the OS / Systems Files; Library; Apps on the SSD and Data such as movies; photos; music on the HDD. I have CarbonCopyCloner and understand what I need to do in order to clone Yosemite onto the SSD from the HDD. As the equipment is new, I won't be migrating any Apps from the HDD that don't actually come with the OS. However, I want to immediately start loading in other programs from my Macbook Pro. I presume I'm connecting the Macbook through Firewire or Thunderbolt to the Mini and then opening up the Finder on the Mini. This may be an obvious question, but will I will be seeing the Mini SSD and HDD drives, along with the MBP, on the Mini Finder and need to simply select which drive I want to copy the programs over to? With regards to accessing Data on the HDD and Apps on the SSD. Will I need to continually switch back and forth between finders for each drive? If I open a Photoshop file (for example) on the HDD is it automatically linked to the Photoshop App on the SDD or do I need to establish Symlinks first. If I do, there seems to be appropriate information here: https://gigaom.com/2011/04/27/how-to-create-and-use-symlinks-on-a-mac/ Final question; My workflow has been to work with many files and (alias) folders on my Desktop. Would I put the Desktop on the SSD or HDD and does it even matter? Many thanks!
