What it is: Apple released the latest version of macOS 10.13.1.
The first rule of updating anything on your computer is to make sure you have backups. That’s because operating system updates can completely wreck a computer so plan on it. Of course, operating system upgrades tend to be much smoother and more reliable than the old days of Windows updates that often caused more problems than they solved. One reason why people tend to prefer the Macintosh over Windows PCs is because the Macintosh is generally far more reliable than a Windows PC where operating system updates actually fix problems rather than create new ones.
In general, it’s best to keep your operating system up to date as often as possible because the last thing you want to do is update your computer from a really old version of the operating system to the latest version. That’s a recipe for disaster. If you keep your operating system version up to date, then the transition from your current version to the latest version will be minimal and likely far more successful.
The latest version of macOS fixes a huge potential problem involving a flaw known as KRACK wi-fi exploit that allows hackers to potentially compromise a WiFi connection. That’s why you want the latest version of macOS to guard and protect your Macintosh against this problem.
Other than patching this potentially dangerous flaw, macOS simply fixes other minor bugs to make your Macintosh more reliable. When updating a Macintosh to a new version of an operating system, you can basically let the process go and come back to your Macintosh later when the update process is done. When updating a Windows PC, you often have to hold your breath and pray nothing goes wrong. In most cases, nothing will go wrong but the experience in updating other operating systems other than macOS isn’t always fun, consistent, or reliable.
This simple difference between macOS and Windows highlights the reason why Macintosh users love their computers while Windows PC users generally tolerate their PCs. When you want security and reliability with fewer headaches, you generally want an Apple product like the Macintosh.
