- Hello, I just want to ask, how can I upgrade my Mid 2011 iMac to latest supported OSX. I'm currently on 10.7.5 and whenever I try to update everything is not supported High Sierra/Catalina (requirements is 10.8 and above). Is there a way to update without official channels?

Use Software Update
- Choose System Preferences from the Apple menu , then click Software Update to check for updates.
- If any updates are available, click the Update Now button to install them. Or click “More info” to see details about each update and select specific updates to install. You might be asked to enter your administrator password.
- When Software Update says that your Mac is up to date, the installed version of macOS and all of its apps are also up to date. That includes Safari, Music, Photos, Books, Messages, Mail, Calendar and FaceTime.
- To automatically install future updates, including for apps that you got from the App Store, select 'Automatically keep my Mac up to date'. Your Mac will notify you when updates require it to restart, so you can always choose to install those later.
Linux/BSD/OSX With the exception of Linux penetration testing distributions, packages are usually out of date ( OS X is the exception). In this case, uninstalling the package and installing from sources is the recommended way to go.
