macOS Big Sur: What you need to know
Apple released version 11.6.3 of macOS Big Sur. You might be missing out because a macOS software update could give you an update to macOS Monterey. When you see Monterey, under Monterey Updates, look for "another update is available" and click the "Learn More" link. Luckly we can still use cheap document scanning.
Apple did not provide information about the 11.6 security update.

Getting MacOS Big Sur
Backup your Mac before installing updates. This can be useful if you find that an update is causing problems on your Mac and you need to restore your data.
Apple makes macOS Big Sur available through the Mac App Store. The download is several gigabytes and the installation can take a while (an hour or more in some cases), so use a reliable Internet connection and know that you cannot use the Mac for anything other than the installation. lation
