I also have alot of newspaper-style prose captions stored as metadata in the Comments pane for quite a few photos. I have a lot of time and effort invested in organizing Events with titles that I wrote like highly abbreviated summaries. This is tremendously disappointing, as Apple's new official Photos app seems to be more like iPhoto Lite, or iPhoto 2004. I am aware that iPhoto is EOL'd, meaning Apple no longer supports it. Now on Sierra, and so far, iPhoto is still working. Both machines use the same iPhoto library (library stored on an external portable hard drive), plugged into either computer (one at a time) via USB cable. I upgraded both machines to MacOS 10.12 Sierra recently. My other family members use iPhoto 9.6.1 on a MacBook Pro. I have iPhoto 9.6.1 installed on my iMac. My family has an interesting arrangement. Apple's concept of a well-designed 'digital shoebox' has proven itself invaluable, time and time again. I rely heavily on iPhoto's proprietary features, and have been since I started using the first version of iPhoto when Apple released it well over a decade ago.

I have an iPhoto library that contains about 65,000 images.

What is iphoto 9.6.1
