same here, my macbook shutdown during sleep :(
There is no way to do that by using pure SwiftUI. But we can access NSScrollView to make magical:
Create NSViewAccessor => helping access NSView of a SwiftUI View
extension View {
func onNSView(added: @escaping (NSView) -> Void) -> some View {
NSViewAccessor(onNSViewAdded: added) { self }
}
}
struct NSViewAccessor<Content>: NSViewRepresentable where Content: View {
var onNSView: (NSView) -> Void
var viewBuilder: () -> Content
init(onNSViewAdded: @escaping (NSView) -> Void, @ViewBuilder viewBuilder: @escaping () -> Content) {
self.onNSView = onNSViewAdded
self.viewBuilder = viewBuilder
}
func makeNSView(context: Context) -> NSViewAccessorHosting<Content> {
return NSViewAccessorHosting(onNSView: onNSView, rootView: self.viewBuilder())
}
func updateNSView(_ nsView: NSViewAccessorHosting<Content>, context: Context) {
nsView.rootView = self.viewBuilder()
}
}
class NSViewAccessorHosting<Content>: NSHostingView<Content> where Content : View {
var onNSView: ((NSView) -> Void)
init(onNSView: @escaping (NSView) -> Void, rootView: Content) {
self.onNSView = onNSView
super.init(rootView: rootView)
}
@objc required dynamic init?(coder aDecoder: NSCoder) {
fatalError("init(coder:) has not been implemented")
}
required init(rootView: Content) {
fatalError("init(rootView:) has not been implemented")
}
override func didAddSubview(_ subview: NSView) {
super.didAddSubview(subview)
onNSView(subview)
}
}
2. Hide scroller of NSScrollView
	List{
		 ...
}.onNSView(added: {nsview in
let root = nsview.subviews[0] as! NSScrollView
root.hasVerticalScroller = false
root.hasHorizontalScroller = false
})
