MacOS is the gold standard for all desktop computer operating systems. It offers an experience that is created to make it as easy as possible for the user to focus on getting their work done, and not fussing with the idiosyncrasies and anomalies of that operating system. There are hundreds or maybe thousands of small details that make Mac support Sydney different, or maybe it would be more accurate to say that there are hundreds or thousands of details that Windows and Linux lack which make up the difference, since Apple created the desktop computer/personal computer market and Microsoft, Linux and everyone else simply copied Apple.
Apple has a focus on making things work correctly, smoothly, effortlessly and they also focus on stability, safety, security and privacy.
MacOS is also special because Apple has an intense focus on privacy, anti-virus capabilities and superior security capabilities. Mac IT support is also special because it is based on UNIX, so it inherits UNIX’s famous stability, security and reliability. Apple takes the safety and security of FreeBSD, OpenBSD, NetBSD, etc. and enhances it with its own software security components (as well as more secure hardware) for security and privacy that exceeds Windows and Linux. A great example of that is when Apple notified the Linux open-source community that OpenSSL is so old that it was full of security flaws and needed to be replaced. macOS is special because Apple actually cares about the user experience of its clients.
