1. Download Xcode Mac Os X 10.6 8
2. Ilife Mac Os X 10.6.8

Updated and republished for macOS 11.0.1; skip it unless you really really care about all the macOS releases. Originally published on November 14th, 2005.

Below the break is a table showing all major releases of macOS (previously Mac OS X) from the public beta through the latest public version, which is 11.0.1, as of November 12th, 2020—the 140th release in total.

• For over a year now, I've been using XCode 4.5 to build an app using the OS X 10.7 sdk, with target deployment to 10.6. The app runs perfectly well on 10.6, 10.7, 10.8, and 10.9. But when I run it on 10.10, I get a message in the Console saying 'Cannot enforce a hard page-zero' for the app.
• Mac OS X 10.6.8 Snow Leopard is an upgrade to the previous version of OS X Leopard. This update does not have stacks of new features, rather overall improvements and efficiency upgrades. This version of Apple's OS also has a reduced footprint.

Although you probably want 4.2.1, not the original 4.2. Besides the fact that you generally want the latest patch release, in this case, many of the new changes in 4.2 were buggy (e.g., 'convert to ARC' would often just hang forever, trying to add iCloud entitlements to an existing project sometimes failed, ) until 4.2.1 – abarnert Jun 14 '12 at 17:59.

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.)

Note: The Days column reflects the number of days between releases.

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.

Some random notes, updated from the original post:

• Starting with the Public Beta and up through 11.0.1, there have been 141 macOS releases, both major and minor. This figure includes the one odd macOS X release: 10.2.7. This version was only for the then-new PowerMac G5 and the flat panel iMac G4, and was never generally released.
• As of November 12th, 2020 (11.0.1's release date), it's been 7,365 days since the Public Beta was released. So on average, we've seen some sort of update every 52.25 days.
• The shortest time period between any two releases is six days, which is how quickly the 10.15.5 Supplemental Update 1 came out after the 10.15.5 release.
• The longest time period between any two minor releases is 165 days, which was how long we waited for the 10.4.9 update. (Tecnically, it's actually the 192 day interval between the Mac OS X Public Beta and version 10.0, but I'm counting from the official 10.0 release.)
• The smallest update was 10.3.1, at only 1.5MB. The largest (non-combo, non-main OS release) update was 10.15.1 at 5.3GB.
• The '???' entry for Size on a given release indicates I was unable to find the size. Feel free to contact me if you can help replace any of the '???' entries.

And now, gratuitous graphics…

Releases by version number

Releases by year

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.

This chapter shows you how to install MacPorts and its prerequisites step-by-step. Note that the section about installing Xcode is macOS-specific. If you wish to install MacPorts on another platform, first make sure you have a working C compiler installed, skip ahead to installing MacPorts from source, and continue to the end of the chapter.

Xcode is a package provided by Apple containing compilers, libraries and additional tools required to develop applications for macOS.

Note

Always make sure to install the latest available version of Xcode for your macOS release; using outdated versions of Xcode may cause port install failures. Also note that Xcode is not updated via OS X's Software Update utility on OS versions prior to 10.6, and is updated via the Mac App Store starting with 10.7.

Follow the instructions for your version of macOS:

Download the latest version of Xcode from the Apple developer website or get it using the Mac App Store.

Once you have Xcode installed, open a terminal, run xcode-select --install, and click the Install button to install the required command line developer tools. Don't worry if you see a message telling you the software cannot be installed because it is not currently available from the Software Update Server. This usually means you already have the latest version installed. You can also get the command line tools from the Apple developer website.

Download the latest version of Xcode from the Apple developer website or get it using the Mac App Store.

Xcode 4.3 and later do not automatically install the command line tools, but MacPorts requires them. To install them, open the Xcode application, go to the Preferences window, to the Downloads section, and click the Install button next to Command Line Tools. Be sure to return to this window after every Xcode upgrade to ensure that the command line tools are also upgraded.

If you wish to create Installer packages with port pkg, you will also need to install PackageMaker, which is in the “Auxiliary Tools for Xcode” package as of Xcode 4.3. The download page for this package can be opened via the Xcode -> Open Developer Tool -> More Developer Tools... menu item. After downloading and mounting the disk image, drag the PackageMaker application to your /Applications directory.

If you are using Mac OS X 10.6, there are two branches of Xcode which could be considered to be the latest, 3.2.x and 4.x. Xcode 4 costs money, but Xcode 3 is still available free of charge. There are two options for downloading it:

1. Xcode 3.2 - smaller download, but you will need to run Software Update after installing to get the latest version. Note that Apple might at some point discontinue providing these updates via their update servers.

2. Xcode 3.2.6 and iOS SDK 4.3 - includes the iOS SDK which is not needed for MacPorts.

Both are available from the Apple developer website. You may also be able to install Xcode 3.2 from your Mac OS X 10.6 DVD and then run Software Update to get the latest version.

Ensure that those of the following options that are available in the installer for your version of Xcode are selected:

If you have an earlier release of Mac OS X, you may download the latest version of Xcode for Mac OS X 10.5 (Xcode 3.0 and Xcode 3.1 Developer Tools) or 10.4 (Xcode 2.4.1 and Xcode 2.5 Developer Tools) from the Apple developer website.

Ensure that those of the following options that are available in the installer for your version of Xcode are selected:
