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.
Download Mac Os X Yosemite 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.
Using Windows to create an USB flash drive OS X Yosemite installer requires third party software beyond just TransMac. The steps below outline one possible method for creating an USB flash drive OS X Yosemite installer using Windows and other free third party tools.
Use Microsoft Edge (or some other web browser) to download the following installers to your Downloads folder. The file names are current as of September 22, 2022. If both 32 bit and 64 bit versions are available, the 64 bit version is given in the table.
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.
So my next option is to create a bootable USB pen which is where I'm having trouble. I have downloaded the Yosemite installer dmg. I have a MacBook Pro M1 and when I mount and then try to run the Yosemite installer, of course it crashes out with the error saying I can't install it on this computer. Without the installer running in the Applications folder, I can't follow any of the steps on the Apple Support site (createinstaller terminal code process) or via any tutorials on YouTube or whatever comes up on Google.
However, I found an article with information on how to download the Snow Leopard iso and further in the thread it talks about how to turn that into a bootable USB pen using Big Sur - -to-create-a-bootable-os-x-snow-leopard-usb-drive
Deciding where to install the old macOSYou can choose and configure the location (disk/partition) on which you want to install your old macOS version. This can be done from the installer on the USB drive. It has features like Disk Utility built in to it. But I like to plan ahead. I started Disk Utility before using the USB stick to create a new partition on an external USB SSD for my new Yosemite instance to live, as you can see here:
OS X 10.10 Yosemite, the much-awaited latest version of OS X Operating System from Apple, was announced and soon made available to public. As soon as the launch of latest Apple desktop OS happened, there were instant comparisons between OS X Mavericks and OS X Yosemite. Macbook users or iMac users can get free download of Apple OS X Yosemite from Mac App Store to check out its various features. In this article, we shall go through useful tips to upgrade to OS X Yosemite from OS X Mavericks as well as ways to clean install Yosemite from scratch after formatting.
Continue with the free upgrade by clicking the relevant OS X option. Once the 5.16 GB file is downloaded, it would trigger the launch of OS X Yosemite Installer. Carry out the installation on your chosen hard drive after agreeing to the Apple terms & conditions.
I have tried to share useful tips related to different ways of upgrading or downloading the latest Mac OS X. I hope you would find this useful while carrying out the relevant complete download OS X 10.10 Yosemite. Please feel free to ask Yosemite installation queries or share your experience!
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.
Once you've obtained all of the necessary materials, connect the USB drive to your Mac and run the Diskmaker X app. The app will offer to make installers for OS X 10.8, 10.9, and 10.10, but we're only interested in Yosemite today.
Diskmaker X has actually been around since the days of OS X 10.7 (it was previously known as Lion Diskmaker), but it's more important now because Apple has made alterations to the installer that prevent easy USB drive creation using the built-in Disk Utility app. It's still possible to create a disk manually using a Terminal command (which we'll go into momentarily), but Diskmaker X presents an easy GUI-based way to do it that is less intimidating to most people.
If you don't want to use Diskmaker X, Apple has actually included a terminal command that can create an install disk for you. Assuming that you have the OS X Yosemite installer in your Applications folder and you have a Mac OS X Extended (Journaled)-formatted USB drive named "Untitled" mounted on the system, you can create a Yosemite install drive by typing the following command into the Terminal.
The command will erase the disk and copy the install files over. Give it some time, and your volume will soon be loaded up with not just the OS X installer but also an external recovery partition that may come in handy if your hard drive dies and you're away from an Internet connection.
Once you have space on your computer, figure out what version of OS X you would like to install. On older versions, you can find the previous versions of OS X installed on your Mac by opening the App Store > Applications and viewing your Purchase page. Click the Install button next to the macOS you want to download.
If you used Disk Drill for creating your bootable drive, a window will prompt your actions for using the install disk you made. But if you created your own using Terminal, use OS X Utilities Selector and find Reinstall OS X. Find and select your install disk with your bootable version of your preferred macOS, and click continue through to the license agreement. Once you agree, you should be prompted by the installer. Once the installation is completed, your computer should restart. If it does not restart itself, make sure you restart it normally. The downgrade should be complete!
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.
I got them all to download, except High Sierra. On the app store page for HS I got an Open button, even though I had unmounted my archive volume that contained the HS installer. So I used the macOS High Sierra Patcher tool as you directed, getting the installer download instruction from the Tools menu. Great app. High Sierra was them downloaded to my specified location. So now I have updated apps for all the macOS X installers in your list. However, this was the only one, besides Mojave, that downloaded the app. The other links downloaded dmg copies, which do not contain the usual installer app. So I retained the apps for Mojave, El Capitan and Yosemite. 2ff7e9595c
