I’ve posted a few old links in my time (as I near 4,000 posts it would be hard not to have some that are broken). But Apple App Store downloads seem to do better with not breaking links. So here are some to old versions of macOS and OS X, in case like me, you always seem to need some old thing for testing:

Download Previous Mac Os Versions

While the developer is fixing the problem, try using an older version. If you need the previous version of Skype, check out the app's version history which includes all versions available to download. Download prior versions of Skype for Mac. All previous versions of Skype are virus-free and free to download. So, that’s all about Download Mac OS X 10.4 – 10.15 Original – All Versions. Therefore, all versions of Mac OS X are valid up to date and don’t contain any virus or problems. I hope this article was helpful for you while installing the New Mac OS. Installing Adobe Reader is a two-step process. First you download the installation package, and then you install Adobe Reader from that package file. If you're running Mac OS X 10.9 or later, install the latest version of Reader. For step-by-step instructions, see Install Adobe Acrobat Reader DC on.

Have you noticed that once Apple releases a new version of the Mac operating system (macOS) that previous versions vanish from the App Store? Have you ever needed to reinstall one of these older versions of the Mac operating system (macOS)? It can be challenging to do this since Apple does not make older versions readily available unless you saved your own copy of the installer for the older version. I recently learned that some older versions are still available on the App Store.

Download

[UpdateOctober2019 – Apple now offers a more straight forward way to download older versions of the Mac operating system (macOS) going back to OS X Yosemite (aka OS X 10.10).

How To Download Old Version Of Macos

Links to App Store via Tidbits:

These installers have certificates that are valid until 2029.]

This article on wphosting.tv has links for downloading some older versions of the Mac operating system (macOS). If you think you might ever need to install an older version then I recommend you download the installers now and then save the installer file so you can create your own install disk, if needed. This Apple support article currently provides instructions on how you can create your own installer disk for El Capitan, Sierra, High Sierra and Mojave. Alternatively you could use an application like DiskMaker X.

As of February 2019, Apple has links to get these versions from the App Store:

App Store links are not provided for older versions of the Mac operating system, such as El Capitan (10.11), Yosemite (10.10) or Mavericks (10.9). This is not a surprise since Apple only officially supports and maintains the 3 most recent versions of the Mac operating system (macOS).

Links are also provided for buying an installer from Apple for Mountain Lion (10.8), Lion (10.7) and Snow Leopard (10.6) Over the decades, Apple has vacillated on whether or not they charged for the Mac operating system. The most recent vacillation came with the introduction of OS X Mavericks (aka OS X 10.9) in 2013, when Apple switched to offering it for free. Prior to that, Apple charged for the Mac operating system since the introduction of Mac OS 8 in the late 1990’s.
