Apple should make macOS as the "Mac" app for Vision Pro

[adib]

Post-iPhone Apple doesn't do devices with multiple OSs, never has, never will -Each device has its own OS and you have to buy each separate device to use each of the separate OSs, MacOS, iPadOS, iOS, WatchOS, VisionOS.

... except macOS on Apple Silicon can run iOS and iPadOS applications (if the corresponding app developers do not opt-out). Hence, macOS contains many iOS and iPadOS components to support this case.

The issue is mostly practicality. Medium-range macOS has more memory and storage than medium-range iOS and iPadOS. Similarly, macOS devices are less volume-constrained (for cooling and support of those peripherals). However, eye goggles are very much volume and mass constrained, second only to watches. Remember that Apple had to move the battery pack outside the device to mitigate the user's neck fatigue.
