Mac Bone X Leopard (version x.5) is the sixth major release of macOS, Apple'southward desktop and server operating arrangement for Macintosh computers. Leopard was released on October 26, 2007 as the successor of Mac Os Ten 10.4 Tiger, and is available in two editions: a desktop version suitable for personal computers, and a server version, Mac OS X Server. It retailed for $129 ^[2] for the desktop version and $499 for Server. ^[eight] Leopard was superseded by Snow Leopard (version ten.6) in 2009. Leopard is the final version of macOS to support the PowerPC compages as Snow Leopard functions solely on Intel based Macs.

According to Apple, Leopard contains over 300 changes and enhancements compared to its predecessor, Mac OS Ten Tiger, ^[9] covering core operating organisation components as well as included applications and programmer tools. Leopard introduces a significantly revised desktop, with a redesigned Dock, Stacks, a semitransparent menu bar, and an updated Finder that incorporates the Cover Menstruum visual navigation interface commencement seen in iTunes. Other notable features include support for writing 64-bit graphical user interface applications, an automated fill-in utility called Fourth dimension Machine, support for Spotlight searches across multiple machines, and the inclusion of Front Row and Photograph Booth, which were previously included with only some Mac models.

Apple missed Leopard's release time frame equally originally announced by Apple's CEO Steve Jobs. When starting time discussed in June 2005, Jobs had stated that Apple tree intended to release Leopard at the end of 2006 or early 2007. ^[10] A year afterwards, this was amended to Spring 2007; ^[11] yet, on April 12, 2007, Apple issued a statement that its release would be delayed until Oct 2007 because of the development of the iPhone. ^[12]

New and inverse features [ edit ]

End-user features [ edit ]

Apple tree advertised that Mac Bone X Leopard has 300+ new features, ^[9] including:

• A new and improved Automator , with easy starting points to easily start a workflow. It also can quickly create or edit workflows with new interface improvements. Now information technology can use a new action chosen "Sentinel Me Do" that lets yous record a user activeness (similar pressing a button or controlling an application without built-in Automator support) and replay every bit an action in a workflow. It can create more than useful Automator workflows with actions for RSS feeds, iSight photographic camera video snapshots, PDF manipulation, and much more.
• Back to My Mac , a feature for MobileMe users that allows users to access files on their home computer while abroad from domicile via the cyberspace.
• Boot Camp , a software banana allowing for the installation of other operating systems, such as Windows XP (SP2 or later) or Windows Vista, on a split up sectionalization (or separate internal drive) on Intel-based Macs.
• Dashboard enhancements, including Web Prune, a feature that allows users to turn a office of any Web folio displayed in Safari into a live Dashboard widget, and Dashcode to help developers code widgets. ^[13]
• New Desktop, comprises a redesigned 3-D dock with a new grouping feature chosen Stacks , which displays files in either a "fan" style, "filigree" style, or (since 10.5.2) a "list" style. Rory Prior, on the ThinkMac blog, criticized the shelf-similar Dock along with a number of other changes to the user interface. ^[14]
• Lexicon can now search Wikipedia, and a dictionary of Apple tree terminology every bit well. As well included is the Japanese-language lexicon Daijisen, Progressive East-J and Progressive J-E dictionaries, and the 25,000-word thesaurus Tsukaikata no Wakaru Ruigo Reikai Jiten ( 使い方の分かる類語例解辞典 ), all of which are provided by the Japanese publisher Shogakukan. ^{[15] [9]}
• A redesigned Finder , with features like to those seen in iTunes 7, including Cover Flow and a Source list-like sidebar.
• Front end Row has been reworked to closely resemble the interface of the original Apple TV.
• iCal agenda sharing and group scheduling also as syncing event invitations from Mail. ^[xvi] The icon as well reflects the current appointment even when the awarding is not running. In previous versions of Mac OS X, the icon would show July 17 in the icon any time the application was not running but the current date when the application was running.
• iChat enhancements, including multiple logins, invisibility, blithe icons, and tabbed chats, similar to features present in Pidgin, Adium and the iChat plugin Chax; iChat Theater, allowing users to incorporate images from iPhoto, presentations from Keynote, videos from QuickTime, and other Quick Look features into video chats; and Backdrops, which are similar to chroma keys, but use a real-time difference matte technique which does not crave a greenish or bluish screen. iChat besides implements screen sharing, a feature previously available with Apple Remote Desktop. ^{[11] [17] [18]}
• Mail enhancements including the additions of RSS feeds, Jotter, Notes, and to-dos. To-dos apply a system-wide service that is available to all applications. ^[19]
• Network file sharing improvements include more granular control over permissions, consolidation of AFP, FTP and SMB sharing into one control panel, and the ability to share private folders, a feature that had not been bachelor since Mac Os 9. ^[20]
• Parental controls now include the power to identify restrictions on employ of the Internet and to ready parental controls from anywhere using remote setup. ^[21]
• Photo Booth enhancements, including video recording with real-time filters and blue/light-green-screen applied science.
• Podcast Capture , an awarding allowing users to record and distribute podcasts. It requires admission to a computer running Mac Os X Server with Podcast Producer.
• Preview adds support for notation, graphics, extraction, search, markup, Instant Alpha and size adjustment tools. ^[22]
• Quick Look , a framework allowing documents to be viewed without opening them in an external application and can preview it in full screen. ^[23] Plug-ins are available for Quick Await and then that you lot tin also view other files, such every bit Installer Packages.

• Safari 3, which includes Web Clip.
• Spaces , an implementation of virtual desktops (individually called "Spaces"), allows multiple desktops per user, with sure applications and windows in each desktop. ^[24] Users can organize sure Spaces for certain applications (eastward.g., ane for piece of work-related tasks and one for entertainment) and switch between them. Exposé works within Spaces, allowing the user to see at a glance all desktops on one screen. ^[25] ) Users can create and command upwardly to xvi spaces, and applications can be switched between each one, creating a very big workspace. The car-switching feature in Spaces has bellyaching some of its users. Apple added a new preference in 10.5.2 which disabled this feature, but there were withal bugs found while switching windows. In 10.5.3, this trouble was addressed and was no longer an issue. ^[26]
• Spotlight incorporates additional search capabilities such equally Boolean operators, as well as the power to search other computers (with appropriate permissions). ^[27]
• Fourth dimension Machine , an automated backup utility which allows the user to restore files that have been deleted or replaced by another version of a file. ^[28] Though generally lauded in the press equally a step frontwards for data recovery, Time Auto has been criticized in multiple publications for lacking the capabilities of tertiary-party fill-in software. Analyzing the characteristic for TidBITS, Joe Kissell pointed out that Time Automobile does not create bootable copies of backed-up volumes, does not back up to Airdrome Deejay hard drives and will not support FileVault encrypted habitation directories until the user logs out, concluding that the feature is "pretty good at what it does" merely he will only use it as part of a "broader backup strategy". ^{[29] [30] [31]} One of these issues has been resolved, nonetheless; On March nineteen, 2008, updates were released for AirPort and Time Automobile, allowing for Fourth dimension Machine to use a USB hard disk which has been connected to an Airdrome Extreme Base of operations Station. ^[32]
• Universal Access enhancements: significant improvements to applications including VoiceOver, along with increased support for Braille, airtight captioning and a new loftier‐quality Spoken language synthesis voice. ^[33]
• Many changes to the user interface , such as a transparent menu bar, new icons, and a 3D Dock. Equally well as this, the Apple icon is at present black instead of blue. R.L. Prior, on the ThinkMac blog, criticized a number of changes to Leopard's user interface, including the transparent menu bar and the new folder icons. ^[14] Decreased transparency of the menu bar, along with the ability to disable the card bar transparency were added with the ten.5.2 release on February 11, 2008. ^[34]
• Russian linguistic communication support, bringing the full to eighteen languages. ^[35]
• Leopard removes support for Classic applications. ^[36]
• Introduced the Alex vocalisation to VoiceOver .

Programmer technologies [ edit ]

• Native support by many libraries and frameworks for 64-scrap applications, assuasive 64-bit Cocoa applications. Existing 32-bit applications using those libraries and frameworks should proceed to run without the need for emulation or translation. ^[37]
• Leopard offers the Objective-C 2.0 runtime, which includes new features such equally garbage collection. Xcode 3.0 supports the updated language and was itself rewritten with it. ^[38]
• A new framework, Core Blitheness, allows a developer to create complex animations while specifying but a "start" and a "goal" space. The main goal of Core Animation is to enable the creation of circuitous animations with modest amounts of program code.
• Apple integrates DTrace from the OpenSolaris projection and adds a graphical interface chosen Instruments (previously Xray). DTrace provides tools that users, administrators and developers tin can apply to tune the performance of the operating system and the applications that run on it. ^[39]
• The new Scripting Span allows programmers to apply Python 2.5 and Ruby 1.viii.half dozen to interface with the Cocoa frameworks. ^[40]
• Red on Rails is included in the default install.
• Leopard'southward OpenGL stack has been updated to version 2.1, and uses LLVM to increase its vertex processing speed. ^[41] Apple has been working to go LLVM integrated into GCC; ^[42] LLVM's use within other operating system facilities has non been announced.
• The Graphics and Media State of the Matrimony address confirmed many other features are possible because of Core Blitheness, such equally live desktops, improvements to Quartz Composer with custom patches, a new PDF Kit for developers, and improvements to QuickTime APIs.
• The FSEvents framework allows applications to register for notifications of changes to a given directory tree. ^[43]
• Leopard includes a read-only implementation of the ZFS file system.

In mid-December 2006, a pre-release version of Leopard appeared to include support for Sunday'south ZFS. ^[44] Jonathan Schwartz, CEO and President of Sun Microsystems, boasted on June six, 2007, that ZFS had become "the file system" for Leopard. ^[45] However, the senior projection marketing manager for Mac Os X stated on June 11, 2007, that the existing HFS+, not ZFS, would be used in Leopard. Apple subsequently clarified that a read-only version of ZFS would be included. ^[46]

• Leopard includes drivers for UDF 2.5, necessary for reading HD DVD and Blu-ray discs using third-party drives, but the included DVD Player software can only play Hd DVDs authored past DVD Studio Pro. ^[47]
• Leopard includes a framework implementing latent semantic mapping for classifying (east.thou. textual) data.
• Leopard is the start operating system with open source BSD code to be certified as fully UNIX-compliant. ^{[48] [49]} Certification ways that software post-obit the Single UNIX Specification can be compiled and run on Leopard without the need for whatsoever code modification. ^[40] The certification merely applies to Leopard when run on Intel processors. ^[49]
• Leopard includes J2SE 5.0. ^[50]

Security enhancements [ edit ]

New security features intend to provide better internal resiliency to successful attacks, in addition to preventing attacks from being successful in the get-go identify.

Library Randomization

Leopard implements library randomization, ^[9] which randomizes the locations of some libraries in memory. Vulnerabilities that corrupt plan retentiveness often rely on known addresses for these library routines, which allow injected code to launch processes or change files. Library randomization is presumably a stepping-rock to a more than complete implementation of address space layout randomization at a later date.

Application Layer Firewall

Leopard ships with two firewall engines: the original BSD IPFW, which was present in earlier releases of Mac Bone Ten, and the new Leopard Application Layer Firewall. Different IPFW, which intercepts and filters IP datagrams earlier the kernel performs significant processing, the Application Layer Firewall operates at the socket layer, bound to individual processes. The Application Layer Firewall can therefore make filtering decisions on a per-application footing. Of the two firewall engines, only the Application Layer Firewall is fully exposed in the Leopard user interface. The new firewall offers less control over private parcel decisions (users tin decide to allow or deny connections arrangement-wide or to private applications, but must use IPFW to prepare fine-grained TCP/IP header-level policies). It also makes several policy exceptions for organisation processes: neither mDNSResponder nor programs running with superuser privileges are filtered. ^[51]

Sandboxes

Leopard includes kernel-level support for role-based access control (RBAC). RBAC is intended to prevent, for case, an application like Postal service from editing the password database.

Application Signing

Leopard provides a framework to utilise public cardinal signatures for code signing to verify, in some circumstances, that code has non been tampered with. Signatures can also exist used to ensure that ane program replacing another is truly an "update", and carry any special security privileges across to the new version. This reduces the number of user security prompts, and the likelihood of the user existence trained to just clicking "OK" to everything.

Secure Guest Account

Guests tin can be given access to a Leopard system with an account that the organisation erases and resets at logout. ^[52]

Security features in Leopard have been criticized equally weak or ineffective, with the publisher Heise Security documenting that the Leopard installer downgraded firewall protection and exposed services to attack even when the firewall was re-enabled. ^{[53] [54]} Several researchers noted that the Library Randomization feature added to Leopard was ineffective compared to mature implementations on other platforms, and that the new "secure Guest account" could be abused by Guests to retain admission to the system fifty-fifty after the Leopard log out procedure erased their home directory. ^{[55] [56]}

System requirements [ edit ]

Apple states the following bones Leopard system requirements, although, for some specific applications and features (such equally iChat backdrops) an Intel processor is required: ^[57]

• Processor: any Intel processor, or PowerPC G5 or G4 (867 MHz and faster) processor
• Optical drive: internal or external DVD drive (for installation of the operating system)
• Memory: minimum 512 MB of RAM (additional RAM (1 GB) is recommended for development purposes)
• Hard bulldoze capacity: Minimum nine GB of disk space available.

Leopard's retail version was not released in divide versions for each blazon of processor, simply instead consisted of ane universal release that could run on both PowerPC and Intel processors. ^[37] Notwithstanding, the install discs that transport with Intel-based Macs merely comprise Intel binaries.^{[ citation needed ]}

Processor type and speed are checked during installation and installation halted if insufficient; however, Leopard will run on slower G4 processor machines (e.g., a 733 MHz Quicksilver) if the installation is performed on a supported Mac and its difficult drive then moved to a slower/unsupported one (the bulldoze may either be an internal machinery or a Firewire external).^{[ commendation needed ]}

Supported machines [ edit ]

Leopard tin can run on the later flat-panel iMac G4s, the iMac G5, iMac Intel Core Duo and iMac Intel Core 2 Duo, PowerBook G4, Power Mac G4, Power Mac G5, iBook G4, MacBook, MacBook Pro, MacBook Air, Mac Pro, Mac Mini, Xserve, Xserve G5, Xserve RAID, Macintosh Server G4, and later eMac models. Leopard can run on older hardware every bit long as they have a G4 upgrade installed running at the 867 MHz or faster, have at least 9 GB costless of hard drive infinite, 512 MB RAM and accept a DVD drive. Leopard however will not run on the 900 MHz iBook G3 models even though they exceed the minimum 867 MHz requirement. This is due to the lack of AltiVec support in the G3 line of processors. Leopard can exist "hacked" (encounter below) to install on these G3 and pre-867 MHz G4 machines but the system may behave erratically and many of the programs, features, and functions may not piece of work properly or at all. As of mid-2010, some Apple computers take firmware factory installed which will no longer allow installation of Mac Os 10 Leopard. These computers only allow installation of Mac OS X Snow Leopard.^{[ citation needed ]} Nevertheless, some computers (such every bit the 2011 model of the Mac mini) tin have Leopard installed on them without hacking.^{[ commendation needed ]}

Usage on unsupported hardware [ edit ]

Some ways of running Leopard on certain unsupported hardware, primarily PowerPC G4 computers with CPU speeds lower than the official requirement of 867 MHz, have been discovered. A common style is use of the program LeopardAssist, which is a bootloader similar in some respects to XPostFacto (used for installing before releases of Mac Os X on unsupported G3 and pre-G3 Macs) that uses the Mac's Open Firmware to tell Leopard that the machine does take a CPU meeting the 867 MHz minimum requirement that the Installer checks for before installation is allowed to commence, when in reality the CPU is slower. ^[58] Currently, LeopardAssist only runs on slower G4s and many people have installed Leopard successfully on these older machines.

Users who have admission to supported hardware take installed Leopard on the supported machine and so simply moved the hard drive to the unsupported machine. Alternatively, the Leopard Installation DVD was booted on a supported Mac, and then installed on an unsupported Mac via Firewire Target Disk Style. Leopard is only compiled for AltiVec-enabled PowerPC processors (G4 and G5) though, too as Intel, so both of these methods volition only piece of work on Macs with G4 or later CPUs. While some of the earlier beta releases were made to run on some later G3 machines (mostly after 800–900 MHz iBooks), no success with the retail version has been officially reported on G3 Macs except for some later iMacs and "Pismo" PowerBook G3s with G4 processor upgrades installed.

For a number of months after Leopard's release it appeared that the simply G3 Macs on which Leopard could be run were those with both an aftermarket G4 processor and an AGP graphics carte, every bit failures with the Os partially booting before crashing were reported on older Macs such as the original tray-loading iMacs and the Beige and Bluish & White Power Mac G3 (all with G4 upgrades as Leopard will not even begin to load without one) whereas it would kicking fine on newer Macs where the Installer restriction had been circumvented. However, more recently it has been reported ^{[59] [60]} that with some more than work and use of kernel extensions from XPostFacto, Tiger and beta builds of Leopard, the Os tin be fabricated to run on G4-upgraded Macs every bit old as the Power Macintosh 9500, despite the lack of AGP-based graphics. While Leopard can be run on whatsoever Mac with a G4 or after processor, some functionality such as Front Row or Time Auto fails to work without a Quartz Extreme-capable graphics card, which many of the earlier G4s did not include in their factory specification.

Since Apple moved to using Intel processors in their computers, the OSx86 community has developed and now as well allows Mac OS X Tiger and afterward releases to be installed and run successfully on non-Apple x86-based computers, albeit in violation of Apple's licensing agreement for Mac Os 10.

Packaging [ edit ]

The retail packaging for Leopard is significantly smaller than that of previous versions of Mac OS 10 (although afterward copies of Tiger besides came in the new smaller box). It besides includes a lenticular cover, making the X announced to float to a higher place a purple galaxy, somewhat resembling the default Leopard desktop wallpaper. ^[61]

Compatibility [ edit ]

After Leopard's release, there were widely reported incidents of new Leopard installs hanging during boot on the blue screen that appears just before the login process starts. ^[62] Apple attributed these problems to an outdated version of an unsupported add-on extension called Application Enhancer (APE), from Unsanity which had been incompatible with Leopard. Some users were unaware that APE had been silently installed during installation of Logitech mouse drivers. Yet, only the users who did not have the latest version of APE installed (2.0.3 at that time) were affected. ^[63] Apple published a knowledge base article on how to solve this problem. ^[64]

Google announced that the Chrome browser will be dropping back up for Leopard starting with Chrome 21. By that time Chrome will no longer automobile-update, and new Chrome installations are not allowed. Their rationale for removal of support is that Leopard is an "OS X version also no longer existence updated past Apple." ^[65]

Firefox also dropped support for Leopard afterwards it shipped Firefox 16 in October 2012. ^[66] TenFourFox is a port of Firefox for the PPC architecture, released after Firefox dropped back up for Leopard.
