Retroactive (right click to open) 1.8Free
Retroactive lets you run Aperture, iPhoto, and iTunes on macOS Catalina. It also supports Xcode 11.6 or 11.5 on macOS Mojave and Final Cut Pro 7, Logic Pro 9, and iWork ’09 on macOS Mojave or macOS High Sierra. Retroactive will automatically scan your Mac to locate an existing Aperture, iPhoto, iTunes, Final Cut Pro 7, Logic Pro 9, Xcode 11.6 or 11.5, or iWork ’09 install. If Retroactive can’t locate an existing install of Aperture or iPhoto, you’ll either be asked to download it from the Purchased list in App Store, or re-install it from a DVD disc.
