Apple ceased support for its professional photo organization and editing application Aperture back in June 2014 and removed it from the Mac App Store in April 2015. Despite the lack of updates, the app still exists and continues to operate as it did at the time development ceased, but it appears that won't be the case for much longer.
MacRumors has discovered, hidden away on a new Apple support page, that Aperture will no longer operate on macOS after Apple's latest operating system, macOS 10. 4 Mojave.
The support page shares how users can move their Aperture libraries to Apple's Photo app, which Apple pitched as a replacement back in 2015, as well as Adobe Lightroom Classic. For those still clinging on to Aperture, it'll either be a matter of not updating past macOS 10. 4 Mojave or getting everything transitioned over to another app by September 2019, when Apple is expected to release the next version of macOS.
