Mac Os X 10.5 9 Update Download
When I tried to download the latest Firefox version, a message said that my operating system doesn't support the upgrade. But the information on download page says MAC OS X 10.5 or better is okay. My system is MAC OS X 10.5.6
Mac Os X 10.5 9 Update Download
The following was culled from Apple's support downloads page, and as such, some of the dates may be off just a bit. If you know for certain that something is incorrect, please let me know and I'll get it fixed. (Scroll to see all entries.)
Some entries may appear out of chronological order (i.e. 10.5 is shown on Oct 26, but above Nov 14 for 10.4.11). This is to keep the version numbers in the proper order, even when an older OS received an update after a major new release came out. This has happened a few times over the years.
A special "thank you!" goes to Mr. Ziebell (for providing some size values on very-old minor updates), and to Benton Quest (for providing size info on all the major releases up through Snow Leopard). See Benton's comment below if you want a nicely detailed history of those early releases.
Any idea why they're calling the Mojave 10.14.6 releases "Supplemental Updates", rather than just upping the version number? I mean, if you've released 3 gigs worth of updates, over 2 months after the original... then you might as well just call it 10.14.7 right?
Mac OS X 10.5 "Leopard": When you're supporting two disparate CPU architectures, everything takes up more than twice the space. Retail OS X Leopard ships on a dual-layer DVD that is absolutely chock-a-block full - 7.553 GB of the 8 GB capacity is taken, but not all of that is OS. The System you run when you boot the DVD is 1.1 GB, there's another gig's worth of 'Optional Installers' (mostly Xcode), but the main folder of installers amounts to 6 GB worth, which happens to include all the language packs, fonts for same, and over 2 GB worth of printer drivers. There's also a 460 MB hidden ISO partition that's got the Boot Camp software on it for Windows. If you add up the size of just the installers used to make up the default OS X - remember, it carries all the baggage needed for both PowerPC and Intel - it adds up to 2.15 GB.
This may be useful to some. Older versions of macOS can be downloaded from the App Store. As of this writting you can get older versions of macOS going back to 10.13 High Sierra. App Store searches will only find the current shipping versions of macOS. For older versions you will need to know the direct App Store link. This article explains how to get it:
The first desktop version, Mac OS X 10.0, was released in March 2001, with its first update, 10.1, arriving later that year. All releases from Mac OS X 10.5 Leopard and after are UNIX 03 certified, with an exception for OS X 10.7 Lion. Apple's other operating systems (iOS, iPadOS, watchOS, tvOS, audioOS) are derivatives of macOS.
A key development for the system was the announcement and release of the iPhone from 2007 onwards. While Apple's previous iPod media players used a minimal operating system, the iPhone used an operating system based on Mac OS X, which would later be called "iPhone OS" and then iOS. The simultaneous release of two operating systems based on the same frameworks placed tension on Apple, which cited the iPhone as forcing it to delay Mac OS X 10.5 Leopard. However, after Apple opened the iPhone to third-party developers its commercial success drew attention to Mac OS X, with many iPhone software developers showing interest in Mac development.
In two succeeding versions, Lion and Mountain Lion, Apple moved some applications to a highly skeuomorphic style of design inspired by contemporary versions of iOS while simplifying some elements by making controls such as scroll bars fade out when not in use. This direction was, like brushed metal interfaces, unpopular with some users, although it continued a trend of greater animation and variety in the interface previously seen in design aspects such as the Time Machine backup utility, which presented past file versions against a swirling nebula, and the glossy translucent dock of Leopard and Snow Leopard. In addition, with Mac OS X 10.7 Lion, Apple ceased to release separate server versions of Mac OS X, selling server tools as a separate downloadable application through the Mac App Store. A review described the trend in the server products as becoming "cheaper and simpler... shifting its focus from large businesses to small ones."
From 2012 onwards, the system has shifted to an annual release schedule similar to that of iOS. It also steadily cut the cost of updates from Snow Leopard onwards, before removing upgrade fees altogether from 2013 onwards. Some journalists and third-party software developers have suggested that this decision, while allowing more rapid feature release, meant less opportunity to focus on stability, with no version of OS X recommendable for users requiring stability and performance above new features. Apple's 2015 update, OS X 10.11 El Capitan, was announced to focus specifically on stability and performance improvements.
In 2020, Apple previewed macOS 11 Big Sur at the WWDC 2020. This was the first increment in the primary version number of macOS since the release of Mac OS X Public Beta in 2000; updates to macOS 11 were given 11.x numbers, matching the version numbering scheme used by Apple's other operating systems. Big Sur brought major changes to the UI and was the first version to run on the ARM instruction set. The new numbering system was continued in 2021 with macOS 12 Monterey, and 2022 with macOS 13 Ventura.
Apple's original plan with macOS was to require all developers to rewrite their software into the Cocoa APIs. This caused much outcry among existing Mac developers, who threatened to abandon the platform rather than invest in a costly rewrite, and the idea was shelved. To permit a smooth transition from Mac OS 9 to Mac OS X, the Carbon Application Programming Interface (API) was created. Applications written with Carbon were initially able to run natively on both classic Mac OS and Mac OS X, although this ability was later dropped as Mac OS X developed. Carbon was not included in the first product sold as Mac OS X: the little-used original release of Mac OS X Server 1.0, which also did not include the Aqua interface. Apple limited further development of Carbon from the release of Leopard onwards and announced that Carbon applications would not run at 64-bit. A number of macOS applications continued to use Carbon for some time afterwards, especially ones with heritage dating back to the classic Mac OS and for which updates would be difficult, uneconomic or not necessary. This included Microsoft Office up to Office 2016, and Photoshop up to CS5. Early versions of macOS could also run some classic Mac OS applications through the Classic Environment with performance limitations; this feature was removed from 10.5 onwards and all Macs using Intel processors.
Applications can be distributed to Macs and installed by the user from any source and by any method such as downloading (with or without code signing, available via an Apple developer account) or through the Mac App Store, a marketplace of software maintained by Apple through a process requiring the company's approval. Apps installed through the Mac App Store run within a sandbox, restricting their ability to exchange information with other applications or modify the core operating system and its features. 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. Applications without any code signature cannot be run by default except from a computer's administrator account.
Support for the PowerPC platform was dropped following the transition. In 2009, Apple announced at WWDC that Mac OS X 10.6 Snow Leopard would drop support for PowerPC processors and be Intel-only. Rosetta continued to be offered as an optional download or installation choice in Snow Leopard before it was discontinued with Mac OS X 10.7 Lion. In addition, new versions of Mac OS X first- and third-party software increasingly required Intel processors, including new versions of iLife, iWork, Aperture and Logic Pro.
The Finder is a file browser allowing quick access to all areas of the computer, which has been modified throughout subsequent releases of macOS. Quick Look has been part of the Finder since version 10.5. 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 10.4, allows rapid real-time searches of data files; mail messages; photos; and other information based on item properties (metadata) or content. macOS makes use of a Dock, which holds file and folder shortcuts as well as minimized windows.
All system icons are scalable up to 512512 pixels as of version 10.5 to accommodate various places where they appear in larger size, including for example the Cover Flow view, a three-dimensional graphical user interface included with iTunes, the Finder, and other Apple products for visually skimming through files and digital media libraries via cover artwork. That version also introduced Spaces, a virtual desktop implementation which enables the user to have more than one desktop and display them in an Exposé-like interface; an automatic backup technology called Time Machine, which allows users to view and restore previous versions of files and application data; and Screen Sharing was built in for the first time.
There are 39 system languages available in macOS for the user at the moment of installation; the system language is used throughout the entire operating system environment. Input methods for typing in dozens of scripts can be chosen independently of the system language. Recent updates have added increased support for Chinese characters and interconnections with popular social networks in China.
