Instructions Apple has stopped supporting OS X Mavericks. Problem There will be no more support provided for OS X Mavericks. New security updates for this operating system will not be provided anymore. This means that with time, it will become increasingly vulnerable to attacks from the internet. This is why we recommend that you stop using OS X Mavericks – especially if the device running that operating system is connected to the internet. Solution If you wish to continue using your computer and do not want to buy a new one, then you should install macOS High Sierra in order to guarantee the continued protection of your device. However, before doing anything, you should back up all your data because sometimes a new installation reformats the hard drive. The million dollar question, though, is if the hardware you own is adequate for this change. Our step-by-step instructions can help you. At your own risk To proceed, you need a special program. Please be aware that it is produced by a different manufacturer, so we are not responsible for its correct and error-free operation.
