If you're still using Apple's Aperture on your MacOS machines, even though Apple discontinued updating it back in 2014, you'll be facing an upgrade decision. MacOS Mojave will be the last version of the OS that will support running Aperture "for technical reasons". Apple's suggestion is to migrate to either Apple Photos or Adobe Lightroom Classic.
The next MacOS is expected to be announced in September. On Apple's support page they give instructions on how to migrate to Photos or LR.
