You may have noticed those little reminders that appear on your Mac every time you open a window reminding you that your computer is not up to date! Contrary to popular belief, updating software is not designed to ruin our lives. It actually helps to keep our computers secure. 

The computer operating system is a set of software programs that run on your device to control its various functions. It can execute a command or control a process. Having an operating system installed correctly can also help prevent computer issues. An operating system update is a process that fixes various problems that prevent your device from performing correctly. It’s important to regularly update your Mac to ensure that it’s running smoothly. Doing so can help improve the performance of your device and prevent it from experiencing issues. Also, having the proper resources is vital to ensure that your Mac is protected and help prevent it from installing harmful software.
