I am absolutely FLABBERGASTED!!
I had iPhoto 9.6 on my computer. I wish to CONTINUE to use it. An Apple update just installed their new Photos and installed a "no-go" sign on my previously perfectly working iPhoto 9.6 and all previous versions.
WITHOUT ANY PRIOR WARNING.
I am NOT interested in having ONLY Photos - I don't mind it being there to try it out, but to UNILATERALLY REMOVE iPhoto is UNACCEPTABLE.
Apple please re-instate it forthwith.
