The software I'm working on uses the Java interface of Bonjour on Mac to discover available machines in the local network. Recently, I found that the software had a problem in Bonjour's Java interface on several Mac machines. But other Mac systems didn't have any problem. I noticed one difference between the failing machines and the other ones - they didn't have /usr/lib/java/libjdns_sd.jnilib. After searching on the web, I found this page of Bonjour: https://developer.apple.com/bonjour/. But I couldn't find out where to download libjdns_sd.jnilib. Neither could I build it easily from the source code without debugging it.
I'm trying to figure out if the Java library of Bonjour is missing on some Mac machines because Apple stopped supporting it or some other reasons. So here are my questions: Does Apple still support the Java interface of Bonjour? How can some Macs have /usr/lib/java/libjdns_sd.jnilib while others don't? Where can I download libjdns_sd.jnilib directly?
(The failing machines run Mac OS 10.9, 10.10, or 10.11. They have Java 1.7 or 1.8 installed.)

After several years away from Delphi (2006) I'm thinking about returning, to try cross platform Windows-OS X development. I have an old Mac Mini, dual booting Win10 and OS X. Everything I've found discussing cross platform Delphi involves configurations with the two OS's running simultaneously, either two machines or one machine+one virtual machine. (With 4G of RAM I don't think I have the memory for the latter option.)
I'm wondering if I could develop in Win10 (without MacOS running), compile, push to source control, etc. and then later pull the files to test in MacOS (without Win10 running)?
You could build OSX applications on Windows without OSX connection with Delphi XE2-XE6.
Since Delphi XE7 OSX SDK and connection profile is needed for building the OSX applications.

I actually built a Hackintosh to learn programming with Xcode. It runs on my Asus X555LA laptop. I downloaded the latest Xcode 9 GM build from the Apple Site (not from App store). After extracting, when I tried to install, it shows "You can't use this version of the application "Xcode" with this version of macOS; You have macOS 10.12. The application requires macOS 10.12.6 or later".
Is there any tweak to make it run on my Sierra 10.12 itself? I can't really think about upgrading the macOS version as it's a Hackintosh. I followed this guide to install macOS on my Asus laptop.
Xcode requires latest macOS, you have no choice, you need to upgrade the macOS version on your Hackintosh. Or better: Reinstall macOS in a recommended way on your PC, if you're doing Hackintosh... :)
The guide you linked is very poor... Never use premade install images, because these have been modified in an uncertain way, and you don't want to install a premade undocumented mess to your computer. It might be packed with threats, malwares, spy tools and so on.. It's the worst thing I can imagine in security aspect to install an OS image from uncertain source.
Also, there is no universal macOS installer for PCs - even though many are trying to find a way to create it: it's a bad idea and it will never succeed because there are so many PC parts, millions of differently built computers..
The only way to create a stable fully functional Hackintosh is to know your hardware and create an installer flash drive for that specific PC. First you have to download the latest macOS Sierra from AppStore, this is the only source that you can trust, because it's downloading from Apple's servers. Then install a small program, called Clover bootloader to the flash drive to make it bootable.
This is the only full and up to date guide for PC laptops. If you have questions, register to the linked site and start a new forum thread posting your questions. They will help you but please read this guide at least 3-4 times carefully because everything is described here.
I am programming software in Java 7. The users of the software are not all up to date (especially the Mac users). Therefore I need an installer (Windows/OSX) that can be easily integrated with the software installation. There is a normal installer for Windows 7 so I am especially focused on finding one for the Mac. Bonus points if it can check for XCode and other requirements too).
I am thinking another option would be to just use some of the libraries from Java 7 (for example the file-system library). However, I think this might not be possible due to the version number in the compiled classes? I couldn't use a Java 6 compiler to compile these libraries either (because they are Java 7 code).
I don't think I am the only one with this problem. There must be a solution somewhere, but I haven't found it.
Any help would be appreciated.
For the best user experience I would recommend using PackageMaker to create a .pkg file which you can then give to your Mac users. That allows them to do a single click-to-install of your app.
Within the package you would bundle your app archive (JAR file), any necessary resources and two scripts, one to check for the existence of Java 7 on the target system, and the other to install it if not found. I would recommend bundling the latest version of OpenJDK7 with your pkg, at least until an official Java 7 SDK is released for the Mac.
JAva 7 is not yet officially supported on Mac OS X, if you are looking for a JAva 7 installer for mac Os X take a look at openjdk-osx-build project on Google Code.
Update: You shouldn't need Java 7 for what your doing.
A better solution is to use Java 6 + Third party JNI libraries (i.e: JNotify,JavaXT...)
Directory listener in Java using JNotify
as for Last Accessed Date you might need to write tiny bit of Objective-C and pass it back via JNI

Mac OS X already comes with Java runtime on Snow Leopard (JRE6)
On Lion it will automatically download JRE6 if application needs it's
You can of course download preview release of JDK7 from Oracle, but remember this is preview software there are some parts still not working yet (for example: Java Web Start)

Edit: Oracle JDK 1.7 Preview Release only supports Mac OS X Lion
I've been building a basic Cocoa application with Core Data and Interface Builder, and no extra coding, frameworks, or header files. I sent it to someone to test on their machine (a last-gen G5 iMac), and they got a message saying that their machine couldn't run it. I discovered the switch to compile for PPC, so I built a PPC version of the application to try out, and that produced the following error message:
You cannot use this version of Application on this version of Mac OS X.
I'm running Xcode 3.2.1, Interface Builder 3.2.1, and OS 10.6.2. The conversation with my tester was a bit confusing; at first it sounded like she only had Tiger on her machine, saying Leopard was incompatible (I corrected and said that Leopard should be, it's Snow Leopard that isn't), and then by the end of the conversation she was about certain that her machine was running Leopard, but had already shut it off by then. So I'm not sure which version of OS X is on the offending iMac, but it's the latest version of either 10.4.11 or 10.5.8 (the tester is in a remote location, so I can't verify personally at the moment).
What can I tweak to try and improve compatibility on my tester's machine?
If they're seeing that message, it's most likely because your app has the LSMinimumSystemVersion key (Minimum system version) set in the Info.plist. You should take this key out or set it to the actual the minimum OS X version you support.
Once you do this, you may well run into the next problem. (Probably a dynamic linker error as a result of using a framework or API that didn't yet exist on 10.4 or 10.5.)
The main problem here is that you're sending it out to a system where you haven't actually tried it. If you plan to support 10.4, 10.5, or both, I highly recommend that you find a spare hard drive, partition it up, and install 10.4.11 and 10.5.8. There are many issues that will crop up on older OS's and if you haven't tried it yourself, it's unlikely it will work smoothly on the first try.
I would like to test software designed to run on a Mac and would need a couple of OS versions (old ones, too) and maybe other Mac software to set up my (virtual) test machines.
For the same scenario on Windows, I can use the licenses available via TechNet or MSDN subscriptions. At the ADC Mac Dev Center, I couldn't find any specific information as to what is available. Does an ADC membership get me downloads of software / OS's to test against? If not, what is available?
Bear in mind that I don't believe any version of Mac OS (barring OS X Server) is licensed for use in a VM. In theory, if you want to test different versions of the OS you'll need to do either multiple installs on a single system (My first iMac came with OS 9 and OS X installed this way, not sure you could get multiple OS X versions installed on a single box) or have lots of boxes.
Yes it does. You can download the operating systems as well as betas (although not as early as "proper" beta testers).
