Nice but………...
First, I am using OS X El Capitain. Its Photo program is less than best and this is why I purchased FX. Unbeknownst to me it is not capable of being enabled and used in conjunction with Photo. I learned a valuable lesson. How does FX work? Nothing spectacular. IPhoto worked better. And actually, getting technical, what seems like years ago I had a Sony VAIO with Windows XP. The XP Photo program was beyond excellent and simple to use. I chatted with a Mac representative last night. It seems that there is a weak point between the new operating system being able to enable a higher end photo editing program that can be purchased on the app store. The editing programs need to catch up because they are crashing. I will wait until one has done so, then purchase it.
No desire to leave the nicknam about
