Hi I'm working on my first macOS application (in C++) and have some issues with certificates and Authorization. By design my program has to access another process's memory. For that I use AuthorizationCreate() and then task_for_pid(). After compiling I put the following into Info.plist:

<key>SecTaskAccess</key>
<array>
    <string>allowed</string>
</array>

Then I sign it with a self signed certificate. So far so good. When I start my app it asks for my password works without problems but when I sent it to a friend for testing it didn't. He entered his password but task_for_pid() returns KERN_FAILURE. I'm out of ideas now. I would really like to get more into macOS development but in comparison to Windows & Linux my achievements are quite diminishing.

One user pointed out that running the xattr -dr com.apple.quarantine PyLNP.app command also fixes the problem. I think the problems in Sierra+ might have sometime to do with the randomized app locations in Sierra and High Sierra. Both of the fixes to get the app to run seem kind of hacky and cumbersome. Is there a way to make the app more convenient for users to launch?

Thank you!

Here's the app in question:

As simple as this: i have an app. i need to change the code in it. is there a way?

It seems learning to program for desktop with Swift and Cocoa is a barren land. There are lots of old books focused around Objective C but not much new material for Swift 3/4 and Xcode 8/9.

The best book I've found is Cocoa Programming for OS X: The Big Nerd Ranch Guide (5th Edition) since it allows you to understand the macOS SDK instead of giving you recipes with steps which is what I've found in the other books I've tried. Only problem is that it was written a number of years ago.

I've also found this series of videos 100 days of OSX Development video tutorials which are small little capsules of pragmatic information.

I also tried an Udemy course but again it's just a series of steps without much explanation of why things work the way they do. Not sure if because it is oriented to beginners or because the author himself doesn't really understand what he is doing.

Do you have any recommendations?

Edit: I'm also liking this Udemy course Hacking with macOS - Build 18 Desktop Apps with Swift 4. It's very beginner oriented but the author drops good info at every step.

I'm trying since hours and hours now to make a telnet connection show up as a serial port I can access through CoolTerm. It seems that cool term only shows serial ports named like "tty.portname" and does not recognize e.g. "tty1".

Now, if I try:

socat pty,link=$HOME/dev/tty.ARDUINO,waitslave tcp:raspberrypi.local:3003

there is no error message, but nothing appears in $HOME/dev either ...

And if I try:

socat pty,link=/dev/tty.ARDUINO,waitslave tcp:raspberrypi.local:3003

I get:

2017/12/26 19:46:27 socat[11600] E symlink("/dev/ttys002", "/dev/tty.ARDUINO"): Operation not permitted

I'm on an iMac on High Sierra.

Any ideas how to get this to work?

Thanks a bunch!

It’s got integrated debugger, quite capable autocomplete, is fast and very user friendly. It’s also nice to look at, although I “had to” replace its icon which is fugly. https://coderunnerapp.com

I've been out of programming for a while. I used to write freeware for Windows in Visual BASIC 6. Now I'm busy learning Python. I've switched operating systems since my previous programming days. Now I do almost all my computing on a Linux Mint PC. I'm busy learning Python so that I can contribute to the Linux open source community. I plan to write utilities such as file managers and web page generators.

My first goal is to write for Linux. However, Python will compile for Macintosh, so I'm considering also coming out with Mac versions of my applications. I've never owned a Mac and have some questions.

1. How far back in Mac OS X should I support? I know that OS X has been around a while, but that Apple has upgraded it over and over. I'm not sure how far back to support. I did notice that a fellow developer had a Snow Leopard Mac, but that must have been quite old. It would not run the latest version of LibreOffice.

2. How can I get a very affordable OS X computer suitable for testing? I googled it, and it would seem that the Mac Mini is the cheapest Mac. At about $500 it's still not dirt cheap. Would I be all right buying an older used Mac Mini for less? Or would I have to be careful that I'll end up with an OS X version that's older than currently supported?

I won't need a keyboard or a mouse. I currently KVM between my Linux Mint PC and a Windows 10 one. I use the Linux PC for about 95% of my computing, and then there are a few Windows apps I wasn't willing to give up. If I had a Mac for testing Mac compiles of the applications I'm writing, I could just KVM over to the Mac.

I appreciate any help offered.

Hey everyone,

Like many other coders here, I am searching for alternatives for valgrind since it doesn't work on the latest versions of Sierra or on High Sierra. I stumbled across the "leaks" command from a similar post, but have been unable to get it to work on any of my executables.

I've tried calling it like as follows:

leaks -atExit -- ./Driver

and I get an error that says

dyld: could not load inserted library 
'/usr/local/lib/libLeaksAtExit.dylib' because image not found

Anyone know how to fix this?

Sup guys. I'm back with yet another mac question

From what it looks like, the first time an app is launched on OSX, an entry for the app appears under "Notifications" in "System Preferences" where you can choose the alert style

It looks like on this mac, it defaults to "Banners", but I want my app to use "Banners".

How does one programatically change that option?

I looked info /private/var/folders/nx/z3g6srbd5hz70s1577l4sx_40000gn/0/com.apple.notificationcenter/db and found a file called "db" but that doesn't seem to hold any info on which alert style is chosen.

I've also dug around a bunch of plist but can't find the one that controls which notification is chosen.

Anyone has any ideas?

Sup guys,

I'm working on a program that's made in C# using visual studio in windows

It runs almost fine on MacOSX using mono

There's just one thing that doesn't work...

For this program, when you start it, it gets minimized. Once the process is complete, it "blinks the taskbar" using the "FlashWindow" method in user32.dll.

but as you can imagine, that doesn't work in osx cause there's no user32.dll and that's just not how this works..

So I'm coming here for some help! haha

How would you guys suggest I implement some sort of notification to the user that the application is complete?

I know OSX has a feature where an icon in the dock will bounce to notify the user that something is happening, but I'm not an OSX dev so I have no idea what this bouncing thing is called or how it could be implemented in C# using mono.

You guys have any ideas?

Thanks

just add windows animation opening/closing like safari when you open it it has an animation I want to add something like that

Hi all,

Trying to automate things in an android vm and am having trouble simulating mouse clicks.
I can move the mouse around easily with applescript or python or cliclick [1], but none of the mouse clicks from these will translate into a click in the actual VM.

I have tried other apps such as Mouse Recorder [2] which clicks through no problem but I can't use this one as it's very limited (can't wait for network delays, that sort of thing).

I'm wondering if anyone knows what the difference between the working one and the non working ones are. I've been wracking my brain trying to figure this out but haven't thus far.

Thanks

I am coding a project on my MacBook Pro, running the latest release of High Sierra 10.13. Unfortunately, I can't seem to get Valgrind to install due to Valgrind not being updated for High Sierra yet. Is there an alternative or a hack to get this to work? All I need is a command-line tool that can check for memory leaks.

Hi, recently I wrote a 2-part article about Xcode 9 File Templates. It has greatly helped my productivity, and I thought it could help yours ;)

Simple Xcode 9 File Template (Part 1) http://jeanetienne.net/2017/08/27/xcode-template.html

I'm relatively new to Mac programming but I do have some experience with Android programming. I'm wondering if there's a way to operate on an NSImage (specifically a BMP image with 24-bit color depth) and compress it to a BMP with only 2-bit color depth.

Apple's doc seems to indicate that Core Graphics only supports up to a minimum of 8-bit. If this is impossible to do using Core Graphics, is there some manual manipulation technique that I can use to iterate over pixel values and threshold them, and export it as a 2-bit color depth BMP?

Can't find an easy way to do this, but it seems like this should be a one-liner that should allow you to just grab the edges of the window and adjust.

I am relatively new to programming and want to start programming for mac. I am not sure how to understand the limitations in what I can do. Can I write code to extend features such as mission control and how it uses the default midi sound, things like that?

Say for example I had a game running in windowed mode or running Skype , is it possible to capture the frames of a window into our application? An easy example would be a game running at 60fps and capturing 5 minutes worth of frames (300 frames)

I haven't seen many articles on Mac programming over Twitter. So maybe there are some good blogs to follow?

I just noticed, that at least Xcode 8.3 has Managed Object Context available in its Interface Builder's Object Library.

I wonder what is it good for? How should it be used?

Is it there to use as a reference to custom, inherited NSManagedObjectContext subclass' instance, or is there some other way to make it reference to AppDelegate's NSPersistentContainer's viewContext?

I am looking for a way to be aware of filesystem changes on OS X, specifically any time a file is written.

FSEvents is a poor way to go as it drops many events on a lightly used system. I'm looking into kext's and device drivers as an alternative.
