Retroactive only receives limited support. Run Aperture, iPhoto, and iTunes on macOS Sonoma, macOS Ventura, macOS Monterey, macOS Big Sur, and macOS Catalina. Xcode 11.7 on macOS Mojave. Final Cut Pro 7, Logic Pro 9, and iWork ’09 on macOS Mojave or macOS High Sierra.
Aperture is generally not able to run in a VM because there's no support for graphics acceleration in macOS versions where Aperture is a supported app.
Big Sur introduced paravirtualised graphics drivers, so Big Sur VMs do theoretically have graphics acceleration.
Has anyone tried running a Retroactive converted Aperture install in a Big Sur VM to see if it works?
Just wondering:
