Make a backup
Before installing any upgrade, it’s a good idea to back up your Mac. Time Machine makes it simple, and other backup methods are also available. Learn how to back up your Mac.
Get connected
It takes time to download and install macOS, so make sure that you have a reliable Internet connection. If you're using a Mac notebook computer, plug it into AC power.
Download macOS Sierra
For the strongest security and latest features, find out whether you can upgrade to macOS Catalina, the latest version of the Mac operating system.
If you still need macOS Sierra, use this link: Download macOS Sierra. A file named InstallOS.dmg will download to your Mac.
Install the macOS installer
Double-click the downloaded file to open a window showing its contents. Then double-click the file within, named InstallOS.pkg.
Follow the onscreen instructions, which will guide you through the steps necessary to install.
Begin installation
After installation of the installer is complete, open the Applications folder on your Mac, then double-click the file named Install macOS Sierra.
Click Continue and follow the onscreen instructions. You might find it easiest to begin installation in the evening so that it can complete overnight, if needed.
Allow installation to complete
Please allow installation to complete without putting your Mac to sleep or closing its lid. Your Mac might restart, show a progress bar, or show a blank screen several times as it installs both macOS and related updates to your Mac firmware.

It does this by creating a 'Virtual Private Network', or 'VPN' to the OpenVPN server using a program named 'OpenVPN', which is included within the Tunnelblick

application. When you connect through a VPN, your computer sends some or all network traffic through a 'tunnel' to the VPN server, which then passes on your network traffic to a local network or the Internet. It is as if you were connecting to the network or Internet through the VPN server instead of your computer. Normally, all traffic between your computer and the VPN server is encrypted.VPNs are primarily used for three purposes (sometimes all three simultaneously):
- To securely connect a computer to the Internet, even though it may be connecting through an untrusted network (a wireless network at a hotel or airport, for example);
- To securely connect a computer to the Internet as if it were located somewhere else (connect a computer in the USA as if it were located in the UK so that BBC content may be accessed, for example); and
- To securely connect a computer to a company's internal network or some part of it (a branch office, for example).
Mac Os
In addition to Tunnelblick for macOS, you need access to a VPN server. Your company may provide one, or you can obtain VPN service from any of several VPN service providers, or you can use another one of your computers or a router to act as a VPN server.
