Why does Safari crash so often?
Why does Safari crash so often? The more you have running on your Mac, the more of its resources you'll use. If you have other apps running and lots of tabs open in Safari, that can cause drag, making it freeze or even crash. Clearing your RAM can help, and it's easy to do with MacKeeper.
Can Safari have a virus?
Even the macOS is vulnerable to browser hijackers, adware, and other malware these days. If you consider intrusive pop-ups or strange extensions showing up in your Safari browser, you're almost certainly dealing with the Safari virus.
