If you're using a Mac with OS X 10.5 (Leopard) or older, you must first purchase a copy of OS X 10.6 (Snow Leopard) and install it on your Mac before you'll be able to update Safari.
Safari is the best way to see the sites on i Phone, i Pad, and Mac.
To make sure that it's up to date, you should keep your device's copy of i OS up to date, because doing this will ensure that Safari is up to date as well.Google Chrome, Mozilla Firefox, Internet Explorer, Safari and Opera. They're all web browsers, and they all need to be kept up to date to stay safe online. Outdated versions of browsers can leave you and your personal information open to hacks. Each of these has multiple versions out there at any given time, as updates are released, and some people opt to update, but others don't. Was told I need to clean-install OS on my Mid 2014 MBP 15.4".I have CCC for backing up Mac files, but I have a Windows partition that would need another backup software.
