You may now be asked to confirm whether you want to use the BlueStacks. Here, double-click on the BlueStacks icon in order to begin the installation process. Once it gets downloaded onto your Mac, double-click on it. The BlueStacks Installer will now automatically begin to download on your Mac. It also includes Gatekeeper, a new security feature that helps you keep your Mac safe from malicious software by giving you more control over what apps are installed on your Mac. The 10.7.5 update is recommended for all OS X Lion users and includes general operating system fixes that improve the stability, compatibility and security of your Mac. If you’re running Snow Leopard (10.6.8) or Lion (10.7) and your Mac supports macOS High Sierra, you will need to upgrade to El Capitan first. Then you can upgrade from that to MacOS High Sierra. Additionally, Disk Utility 12.1’s “restore” option is no longer available by right-clicking the disk image, but by clicking the right-most button in the application frame. Lion OS 10.7.3 is now available for download in the app store for those who originally purchased 10.7+. When I checked my system 'about this Mac' it says. I need this update as several softwares are not working on this version.
I am not able to update from Mac OS X Lion 10.7.5 (11G63) version to newest version.
