Can I update my iPhotos Apple app with Catalina to 64-bit compatability with MacBook Air?
Can I update Apple iPhone app to Catalina from Sierra on my MacBook Air for 64-bit?
MacBook Air 13″, macOS 11.0
No version of iPhoto will run in Catalina or newer; it depends on a 32-bit library. Launch Photos with the Option key held down, click on Other Library, and choose the iPhoto one; alternatively, switch to a non-Apple product.
