I didn't try, because, like I said, it would be of no use to me, even if it did work, because the screensaver engine would still receive the event, and kill the screensaver immediately.

Does this mean you’re unable to set up a global event tap/monitor? If you are
able, how are you setting it up?

Re: Screensaver can capture mouse events under Catalina
Thanks a lot for your response!
Unfortunately, with -addGlobalMonitorForEventsMatchingMask: ,
the event is still passed on to the higher-up objects, so that makes the
screensaver engine terminate the screensaver immediately.

Gabriel, (this is a dup reply, forgot to cc list)
How are you setting up you global event monitor?
I use this to handle catching mouse moved event when my app is not in the
foreground…. maybe you use something like this
Just watch out for a lot of events and making your app a CPU hog.
[NSEvent addGlobalMonitorForEventsMatchingMask:NSMouseMovedMask
handler:
^(NSEvent * _Nonnull event)
{
// Do stuff to handle events that I care about
}];

Re: Screensaver can capture mouse events under Catalina
I have to say, I'd be surprised if this were possible. From a security point of view, I can understand why Apple would want to prevent a screensaver from being able to capture keystrokes. > On 25 May 2020, at 11:34 pm, Michael Diehr via Cocoa-dev > wrote: > >> On May 25, 2020, at 12:43 PM, Gabriel Zachmann wrote: >> [...] >> Unfortunately, it seems that I still cannot get key events. >> Best regards, Gabriel > > I tried what feels like a thousand different variations and could not get key > events under Catalina screensaver. > If you can figure it out, please do share! > Mike > > ___ > > Cocoa-dev mailing list (Cocoa-dev@lists.apple.com) > > Please do not post admin requests or moderator comments to the list. > Contact the moderators at cocoa-dev-admins(at)lists.apple.com > > Help/Unsubscribe/Update your Subscription: > https://lists.apple.com/mailman/options/cocoa-dev/markjallan%40gmail.com > > This email sent to markjal...@gmail.com ___ Cocoa-dev mailing list (Cocoa-dev@lists.apple.com) Please do not post admin requests or moderator comments to the list.

Re: Screensaver can capture mouse events under Catalina
Great question - I'm the author of iScreensaver. Although our editor app is
primarily built using Xojo, the actual .saver file is now a proper Swift .saver
file built using Xcode, which internally runs a JavaScript/HTML rendering
engine in a WKWebView. I mention this detail in case it's important (e.g.
does having a WKWebView matter?)
My experience has been that Catalina tried really hard to break many features
of screensavers.
In any case, here's the code we use for capturing mouse events. Basically you
set up a global handler, and then have to figure out how to route the event
back to the correct screen (on a multi monitor system) and view...
if isCatalinaOrHigher && mainScreen {
func mouseEventMonitor (event:NSEvent) -> NSEvent? {
log("# [\(screenNumber)] mouseDownEventMonitor
event=\(event.description)")
// this is a global handler for the App - so the event may
be from any screen.
// figure out which screen this is and route it
appropriately
for i in 0.. On May 25, 2020, at 6:17 AM, Gabriel Zachmann via Cocoa-dev

Nothing else of interest, AFAICS. No source code available. After you build the screensaver, there is an actual plugin in ~/Library/Screen Savers, which is just a regular screen saver. When the saver runs and you move the mouse, you get an overlay , just like with the video player, with icons like "forward", "pause"; you can click the icons (e.g., pause the slide show).

You could download it and try it out and see how they do things. What does the installer do. Does simply install an app or are there other pieces installed.
