I'll try to keep it brief. I had a 60gb Mushkin SSD in my Macbook White Unibody but I found myself wanting more space. So I bought a Kingston 120gb SSD to replace it with. So, rather than reinstall everything and start fresh, I did the following procedure. -Hooked up external HD -Cloned SSD to HD to boot off of -Booted from USB HD (not SSD) -Once booted, created an image (via superduper) to the external HD of the previous internal SSD -Shut down, installed new SSD -Booted once again from the external HD -Formatted & restored image to new SSD Now it seems with this new SSD my Mac is using more CPU & memory than before. Is this just me or is there something in OSX El Capitan than doesn't play well with cloned/imaged SSD's to new SSD's? Thanks for the help guys!
