Photos received a new Memories feature that automatically created curated collections of users' favorite photos and videos. Sierra also delivered more than 60 security fixes. Metal 2 furthers graphics capabilities and natural language processing, and developers will be able to create interactive virtual reality experiences on a Mac for the first time.
A refreshed Photos app makes searching for and organizing photos easier and contains advanced editing tools. Safari becomes faster and contains new features like Intelligent Tracking Prevention to remove cross-site tracking data from advertisers. Safari also automatically disables those annoying autoplaying videos with audio for a quieter browsing experience. Other features include improved Siri and Spotlight and instant iCloud syncing for Messages. It will be available as a free download on Sept. Its main feature is a new Dark Mode that turns the overall UI dark gray. The new Stacks feature organizes cluttered desktops by automatically stacking similar files into groups, and Gallery View — reminiscent of Cover Flow — lets users visually skim through files.
Preview Panes show file metadata, and Quick Look allows users to rotate, crop and mark up PDFs and trim video clips without opening native applications. The screenshot tool contains new on-screen controls to mark up images and allows users to record video.

This has been cited as an advantage, by allowing users to install apps with confidence that they should not be able to damage their system, but also as a disadvantage due to blocking the Mac App Store's use for professional applications that require elevated privileges. Apple produces macOS applications, some of which are included and some sold separately.
Numerous other developers also offer software for macOS.
Tools such as XPostFacto and patches applied to the installation media have been developed by third parties to enable installation of newer versions of macOS on systems not officially supported by Apple. Except for features requiring specific hardware such as graphics acceleration or DVD writing, the operating system offers the same functionality on all supported hardware.
As most Mac hardware components, or components similar to those, since the Intel transition are available for purchase,  some technology-capable groups have developed software to install macOS on non-Apple computers. These are referred to as Hackintoshes , a portmanteau of the words "hack" and "Macintosh". On June 6, , Steve Jobs announced in his keynote address at the annual Apple Worldwide Developers Conference that Apple would be making the transition from PowerPC to Intel processors over the following two years, and that Mac OS X would support both platforms during the transition.
Jobs also confirmed rumors that Apple had versions of Mac OS X running on Intel processors for most of its developmental life. A new version of Xcode and the underlying command-line compilers supported building universal binaries that would run on either architecture. PowerPC-only software is supported with Apple's official emulation software, Rosetta , though applications eventually had to be rewritten to run properly on the newer versions released for Intel processors.
Apple initially encouraged developers to produce universal binaries with support for both PowerPC and Intel.
Plugins for Safari need to be compiled for the same platform as Safari, so when Safari is running on Intel, it requires plug-ins that have been compiled as Intel-only or universal binaries, so PowerPC-only plug-ins will not work. Support for the PowerPC platform was dropped following the transition. One of the major differences between the classic Mac OS and the current macOS was the addition of Aqua , a graphical user interface with water-like elements, in the first major release of Mac OS X.
Every window element, text, graphic, or widget is drawn on-screen using spatial anti-aliasing technology. New interface elements were integrated, including sheets dialog boxes attached to specific windows and drawers, which would slide out and provide options. The use of soft edges, translucent colors, and pinstripes, similar to the hardware design of the first iMacs , brought more texture and color to the user interface when compared to what Mac OS 9 and Mac OS X Server 1.
According to Siracusa, the introduction of Aqua and its departure from the then conventional look "hit like a ton of bricks. To some extent, Apple has used the successful transition to this new design as leverage, at various times threatening legal action against people who make or distribute software with an interface the company says is derived from its copyrighted design.

Apple has continued to change aspects of the macOS appearance and design, particularly with tweaks to the appearance of windows and the menu bar. Since , Apple has sold many of its Mac models with high-resolution Retina displays , and macOS and its APIs have extensive support for resolution-independent development on supporting high-resolution displays. Reviewers have described Apple's support for the technology as superior to that on Windows.
The human interface guidelines published by Apple for macOS are followed by many applications, giving them consistent user interface and keyboard shortcuts. The graphics system OpenGL composites windows onto the screen to allow hardware-accelerated drawing. This technology, introduced in version The Finder is a file browser allowing quick access to all areas of the computer, which has been modified throughout subsequent releases of macOS.
It allows for dynamic previews of files, including videos and multi-page documents without opening any other applications. Spotlight , a file searching technology which has been integrated into the Finder since version Its functions are to instantly display all open windows as thumbnails for easy navigation to different tasks, display all open windows as thumbnails from the current application, and hide all windows to access the desktop. Features introduced in version The operating system then managed conflicting edits and data consistency.
In more recent releases, Apple has developed support for emoji characters by including the proprietary Apple Color Emoji font. There are 38 system languages available in macOS for the user at the moment of installation; the system language is used throughout the entire operating system environment. Until OS X In Mountain Lion and later, this was merged into the Mac App Store application, although the underlying update mechanism remains unchanged and is fundamentally different than the download mechanism used when purchasing an App Store application.
In macOS Prior to its release, Mac OS X After the immense buzz surrounding Mac OS X Apple has also registered "Lynx" and "Cougar" as trademarks, though these were allowed to lapse. The "PB", as it was known, marked the first public availability of the Aqua interface and Apple made many changes to the UI based on customer feedback. Following some bug fixes, kernel panics became much less frequent.
It featured increased performance and provided missing features, such as DVD playback. Apple released It was discovered that the upgrade CDs were full install CDs that could be used with Mac OS 9 systems by removing a specific file; Apple later re-released the CDs in an actual stripped-down format that did not facilitate installation on such systems. Mac OS X v In addition to providing much improved performance, it also incorporated the most extensive update yet to the user interface. Apple stated that Tiger contained more than new features.
The initial release of the Apple TV used a modified version of Tiger with a different graphical interface and fewer applications and services. On January 10, , Apple released the first Intel-based Macs along with the This operating system functioned identically on the PowerPC-based Macs and the new Intel-based machines, with the exception of the Intel release lacking support for the Classic environment.
