How Do I Turn On Incognito Mode In Safari?
Safari for Mac's version of incognito mode is called Private Browsing. To turn it on, launch Safari and go to the Safari menu to Private Browsing. When you're done, go back to Safari > Private Browsing to disable it.
Starting in the new version of Safari for Mac released with OS X Yosemite, Private Browsing is replaced with Private Mode and it allows you to open a private window from the top menu bar while keeping non-private windows open. To activate it, go to File > New Private Window.
In Safari for iOS, you can switch to Private by pressing the "Private" button on the "new tab" screen. If you're not sure how to get to the "new tab" screen, tab the icon that looks like two squares stacked on another. It can be found at the bottom left corner of the screen in Safari for iPhone and the top right corner in Safari for iPad.
