Using Software Update is faster and easier than upgrading by other methods, and it might require less storage space to download and install the upgrade. Software Update shows only upgrades that are compatible with your Mac.
If the macOS that you want isn't compatible with your Mac or the currently installed macOS, the installer will let you know, and the App Store might prevent you from downloading it. For example, it might dim the Get button, say that the macOS is not compatible with this device, or say that the requested version of macOS is not available.
Downloading and using different Mac OS installers is very common for troubleshooting purposes, for IT staff and admins, and for tinkerers. This article will discuss where to download and access installers for macOS Ventura 13, MacOS Monterey 12, macOS Big Sur 11, macOS Catalina, MacOS Mojave, MacOS High Sierra, macOS Sierra, Mac OS X El Capitan, OS X Yosemite, OS X Mavericks, Mac OS X Mountain Lion, Mac OS X Lion, Mac OS X Snow Leopard, Mac OS X Leopard, Mac OS X Tiger, and others too.
For earlier versions of Mac OS X, including Mac OS X Mavericks 10.9, Mac OS X Mountain Lion 10.8, Mac OS X Lion 10.7, Mac OS X Snow Leopard 10.6, Mac OS X Leopard 10.5, Mac OS X Tiger 10.4, and before, the process to obtain those installers differs a bit.
Another option is to peruse the Apple Vintage Software collection at Archive.org which may have image files of older system restore disks and other older system software, just beware that archive.org is not an official distributor of Apple software so appropriate precautions should be taken and only download from there at your own risk.
The disk image is available here Download OS X Yosemite but if I mount and run it it says cannot install in your computer I need the installer to make a bootable drive like this( bootable installer). I will then run the drive in a separate apfs volume as told by apple here Installing macOS on a separate APFS volume - Apple Support
There are many posts on the Internet where instructions are given for creating OS X USB installers by using the TransMac and other such applications on a Windows machine. Many of these posts assume one is starting with a disk image (.dmg) file made from an existing OS X USB flash drive installer.
An InstallMacOSX.dmg file for OS X Yosemite, can be downloaded from the Apple website How to download macOS. While this file can be restored to a flash drive, the result is not a working OS X Yosemite USB installer.

Use the File Explorer to delete the OS X Install ESD folder, 3.hfs file and InstallAssistant.icns file in your Downloads folder. If you wish, you can also delete the downloaded files. When finished, close the File Explorer window, then empty the Recycle Bin.

The easiest way to install MacPorts on a Mac is by downloading the pkg or dmg for Ventura, Monterey, Big Sur, Catalina, Mojave, High Sierra, Sierra, El Capitan, Yosemite, Mavericks, Mountain Lion, Lion, Snow Leopard, Leopard or Tiger and running the system's Installer by double-clicking on the pkg contained therein, following the on-screen instructions until completion.
This procedure will place a fully-functional and default MacPorts installation on your host system, ready for usage. If needed your shell configuration files will be adapted by the installer to include the necessary settings to run MacPorts and the programs it installs, but you may need to open a new shell for these changes to take effect.
If on the other hand you decide to install MacPorts from source, there are still a couple of things you will need to do after downloading the tarball before you can start installing ports, namely compiling and installing MacPorts itself:

because I have to test my OS X app with an older Mac OS X version (to make sure it is still compatible) I would like to setup a VM with an older OS X Version (El Capitan or Yosemite) using Parallels desktop. In order to create the VM a need the installer package.
About that warning tho...the MAS assumes you're trying to download and install, not just download. Without a computer properly configured to follow thru with an actual install as part of that process, you're stuck.
However, if you have installers for 10.9 Mavericks, 10.8 Mountain Lion, and 10.7 Lion, TidBITS Talk reader gastropod suggested a workaround for their expired certificates. Before you install, set the clock on the Mac to a date when the certificate was valid, perform the install, and then reset the date back after installation. To change the date from Terminal (which is likely all that will be accessible), follow these steps, which set it to 1 February 2016:
Speaking of Terminal, Armin Briegel has written on his Scripting OS X blog that the softwareupdate command has a new option in Catalina that lets you download the full installer for a specific version of macOS. This seems to work with versions of 10.14 Mojave and 10.13 High Sierra, but nothing older.
Is there a way to see when the signing certificates expire I thought I knew how, but when I use that procedure it shows the Mojave and Catalina installers I just downloaded expiring in April of 2021 (which is better than last Thursday, but still only 1.5 years away.)
When I try to get the High Sierra or Mojave installers, the link takes me to a page where the link only takes me to the app store where those installers do not appear anywhere that I can see. The links for El Capitan, Sierra, and Yosemite got me to a page where I could download a dmg so those seem to work.
As others have noted High Sierra and Mojave are obtained via the App Store. I am still using El Capitan but had older copies of High Sierra and Mojave stored on my computer for future consideration. The App Store wanted to open these copies so I had to trash them before the updated copies would download.
In the High Sierra App Store, I get a download button for my purchases. It does not show up in a search, which is where I would get the GET button. I played around with the option, ctrl and command buttons, but no option to get the link.
As I read the article that command is new under Catalina. I explained above I am still running Mojave. I want to be sure I have a Mojave installer before upgrading and optimally already installed on a partition running Mojave with Parallels Desktop before upgrading. In any case this command did not work for me on Mojave, this is the response from terminal:
The day the TidBITS article appeared I tried downloading the installers and had problems downloading the ones from the Mac App Store. I reported the screwup of the missing archived macOS installers to a senior AppleCare advisor. Sure enough, he, too could not download them from the Mac App Store. He agreed it was screwed up and reported it to engineering.
The article lists the Apple support documents for installing Yosemite, El Capitan, Sierra, High Sierra, Mojave and Catalina. Each of the support documents has links to the installers, and according to the senior AppleCare advisor those links are the official way to obtain the installers. 153554b96e
