3, Apple is making major updates to Safari. The browser is getting a Vertical Tabs layout, which can be used instead of the standard horizontal tab bar. It's a change that pairs well with the iPhone Duo 's larger display, but it is available across iPhone, iPad , and Mac. Vertical Tabs are located on the left side of the display and use icons by default to save space, but there is an option to make the tab bar wider to show website titles as well. Vertical Tabs work with both Topics and Tab Groups to keep things organized. Topics are created when automatic Apple Intelligence tab sorting is turned on in iOS 27 . Pinning tabs by dragging, quickly swapping between Tab Groups, and other features also continue to work. The option to turn on Vertical Tabs is located in the Safari settings or in the View menu on Mac and ‌iPad‌. Apple is adding Adaptive Dark Mode for websites that don't have a dark mode design option by default. If you use ‌Dark Mode‌ and then browse to a website with a bright background color, Safari will offer an option to "Try" Adaptive ‌Dark Mode‌. After tapping Try, Safari renders a ‌Dark Mode‌ version of the page that makes the background darker, changes text contrast, inverts logos and graphics, recolors vector artwork, lifts raised surfaces, and rebalances layered shadows. Each website will be adapted based on what's needed to make it readable, so not every tweak is applied to every site.
