Is there a corresponding line of code that sets self.prefController to nil when the window is closed? As I understand it, the property will only be set to nil if it is declared as weak, which is most

I think I would have a property that holds the velocity that is calculated in response to the keyPathsForValues… method being fired. Then just bind to that property. Make sure that everything that is

SMJobBless is a royal pain to get going. By far the easiest (and perhaps coolest) way of running a privileged app (usually for an installer) is to do it through AppleScript. Something like: “do shell

That’s one of the cool things about it. Nothing special about the lower level (main) app. It is simply a standard app. You can either do the installation yourself there, have the top level installer r

John; I suspect you are putting more into the scripting idea than is really needed. The only thing I use AppleScript for is to launch the installer application. That (standard Mac) application is writ

A broken pipe usually means that one end of the connection has been closed for one reason or another. You don’t show the actual read and write code, but that is most likely where the problem occurs. B

Jens; Thank you for the opportunity to expound on this. See below… A look at the discussion for NSFileHandle’s writeData: method provides the following: "This method raises an exception if the file de

Can you publish the actual declarations for myArray and mArray? The ones you show aren’t quite legal and will be rejected by C compilers. There isn’t that much different from regular C. In your code,

One suggestion for testing on a single machine is to use VMware Fusion to create multiple macOS VMs. You will want a system with decent speed, but the environment should do exactly what you need with

It is actually the property flipped on NSView. isFlipped is the getter function. The doc says: "If you want your view to use a flipped coordinate system, override this property and return YES.” I use

Alex, that won’t work. They only will upgrade within a major version. 10.11.6 combo will only upgrade 10.11 versions, not 10.10. The 10.11.6 installer actually is on the app store. There is some metho

In the applications folder. If you think about it, it is an app, right? By the way, the version from the app store is the latest (10.11.6). No need to apply further combo updates. - Jack

If file handlers were thread-specific you would not be able to read files on other threads. They are process-specific, not thread-specific. At its core, select is very much synchronous. This haunted t

Graham - did you ever get a response? This looks to me like you are doing an animation which has completed and is trying to call back to your completion block. For some reason the completion block is

NSView inherits from NSResponder. That gives NSView access to mouseDown, mouseUp and a whole host of other important calls. What this really means is that you can implement - (void)mouseDown:(NSEvent

John; It’s usually a good thing to read the release notes for each version of Xcode. The Xcode 10 release notes directly mention the issue you are facing: Building with libstdc++ was deprecated with X

The About window has no name - the title is blank. it would seem that a more interesting way to do the would be to use the [NSWindow windowNumberWithOptions:] method, which does return an array of win

Alex; I think you may be going down the wrong path on this one. It sounds more like a second instance is being created somehow. Did you guard the init method so that no one can create a second one, or

Hardened Runtime is not currently a requirement for Notarization, but it appears that you have to submit the app using the command-line tool for notarization to happen properly. All my attempts at sub

Have you checked the Notarization report? That will tell you exactly why it failed. Jack
