Your Mac should sync w/your iPhone. I find it easier to edit photos on my iPhone and then upload to my Shutterfly acct - all via mobile. Try to avoid syncing photos or videos to your Mac as you want to keep the speed fast and the more you use the memory up, the slower it will be so just use your Mac for what you really need it for; otherwise you;ll have the same problem as you do with the Lenovo. Unless of course you can afford to buy cloud storage and save everything there but that is a monthly fee.
