What is patching? Patching is another word for updating your operating systems on your server, PCs, Laptops and Macs. It even applies to your smartphone and tablet.

Microsoft and Apple regularly issue updates to their operating systems. These updates typically resolve bugs (errors in the system) and increasingly plug cybersecurity holes. Implementing these updates is called ‘Patching’.

Sometimes the updates include new or improved functionality in the operating system. These are generally referred to as upgrades, but they typically include bug and security fixes too.
