Well, unless you have inside knowledge about Apple’s roadmap, sandboxing is only required for the Mac App Store.

Or are you believing the same 10+ year old conspiracy theory that Apple plans to make it mandatory for apps to be installed from the Mac App Store?

Also Windows 10X is just another failed gimped version of Windows that is suppose to make Windows run better on tablets and low power devices.

I happen to have good guesses reading between the lines, and it quite obvious where required notarization, user space drivers, application entitlements and iOSification of macOS are heading to.

MSIX is what is driving Windows 10X security, which coincidently is the future of Windows package management.

Application entitlements were required shortly after the Mac store launched - over 10 years ago and only for App Store apps. If Apple wants everything to be App Store only, they really are taking their sweet time.

Signed drivers have been a requirement for Windows forever. Apple is actually late to the game.

It’s also well understood that from a security and stability standpoint that moving drivers into user space was preferable.

Catalina has changed that, notarization is now required for everything, not only App Store.

Well, first there is a difference between “notarization” and “sandboxing”. Notarization just requires you to have your app signed, is a completely automated process, and in no way restricts what your app does.

Sandboxing restricts what your app can do and you have to use entitlements to use certain features.

But no, notarization is not “required” and as an end user you can ctrl-click the first time you run an app to bypass it.

Still, give it more 5 years or so.

They said the same thing back when it was announced in 2010....

They also said that Apple would never make notarization a requirement, then came Catalina.

They never said that and in fact it is still not a requirement. You can use the same control click to bypass it that you always could.
