Some of this may be an issue with the size of my library too. I am starting to see creakiness in iPhoto, it crashes more often, and needs rebuilding more frequently than I remember, it seems to be having random troubles reading my SD card fully, not sure if that's a card issue or the software. Sometimes iPhoto is not visible on the Purchases List. Insert the first one and opt to ‘Install Bundled Applications Only.

If iPhoto was installed on your Mac when you go it then it’s on the System Restore disks that came with your Mac. I'm not thrilled about being two generations behind in OS, so may bite the bullet and move to Mojave. If you purchased an iLife Disk, then iPhoto is on it. It appears that iPhoto & Aperture both still run under Mojave, but the new Catalina (10.15.x) is going to break them. I'm not interested in getting into Adobe's pay-by-the-month forever business model either. I have successfully uploaded this onto OneDrive, where it shows up as a folder. I do most editing in iPhoto, but use Aperture for more detailed stuff. OneDrive Files On-Demand Not Working on Mac I am consolidating files from Dropbox onto OneDrive, notably including a 35 GB Apple iPhoto library (nearly 10 years of family pictures).

Also, the editing capabilities I have in Aperture are not available, burning, dodging, spot fixes for contrast and other fine work. I've played with Photos a bit, and am not impressed, the interface is not intuitive (to me), and my sense is Apple wants you to use it so they can sell you cloud space. Go to the Apple menu and choose App Store. If you are running at least iPhoto 9 (iPhoto ’11) then you should be able to upgrade yourself. Primarily as I have not wanted to go through the pain of migrating my 100K + images from a shared iPhoto & Aperture library to Photos. Why is iPhoto not working on my Mac If iPhoto refuses to run because the version is not compatible it just needs to be upgraded to the final version of iPhoto. For a few good reasons and some just plain stubbornness, I've not upgraded from High Sierra (10.13.x) to Mojave (10.14.x)
