Will I lose everything if I update my macOS?
No. Generally speaking, upgrading to a subsequent major release of macOS doesn’t erase/touch user data. Pre-installed apps and configurations too survive the upgrade. Upgrading macOS is a common practise and carried out by lot of users every year when a new major version is released.
Is it bad to update your Mac?
Sometimes updates come with major changes. For example, the next major OS after 10.13 will no longer run 32-bit software. So even if you don’t use your Mac for business, there may be quite a bit of software that will no longer run. Games are notorious for never being updated, so expect that many may no longer function.
