Photos is installed by macOS, like Mail and Calendar, as Larry said. The Photos.app is just a wrapper with calls to system services. That is why the application is so amazingly small, lee than 60 MB, just the size of a large RAW file.
Reinstalling Photos can help, if the problem is system wide and not just happens for your current library or only in your own user account.
To test this, launch Photos from a different user account (see this help page: Isolating an issue by using another user account). If Photos is working perfectly when launched from the Guest User account, the problem is restricted to your current account and trashing plist files or caches, or containers can help, unless your current library is causing the problem. Test with a new test library as well, if Photos is working on a new Photos Library. (https://help.apple.com/photos/mac/1.2/?lang=en#/pht6d60b524)
I recently received a notice to update iPhoto on my Mac (Yosemite, version 10.10.5). The link took me to the message 'This update is not available for this Apple ID either because it was bought by a different user or the item was refunded or cancelled'. Then I opened the iPhoto app [already cancelled by Apple] which took me to a text box that stated 'In order to open iPhoto you need to update to the latest version - the version of iPhoto installed on this Mac is not compatible with OS X Yosemite - download the latest version for free from the Mac App Store.' I clicked the link and was taken to the message 'The item you've requested is not currently available in the U.S. store'. Can anyone direct me to a place where I can download iPhoto's upgrade/replacement - the Photo app for Mac OS X Yosemite? Many thanks.
