[Installer App Download For Mac Os X Yosemite App
Abdul Soumphonphakdy
My App Store option for Yosemite ( -x-yosemite/id915041082?mt=12) says "Downloaded" and it won't let me download any physical file. I looked in my downloads folder and it's not there. The button that reads "Downloaded" is unresponsive, although the dropdown menu does provide options to copy and share the link with others.
I should have been more clear: the app store will not let me download Yosemite on my working iMac desktop computer. I'm trying to create a bootable CF drive so that I can install Yosemite on my laptop computer that has a brand new unformatted HD.
2) Additionally I'm concerned that if I attempt to "install" the "downloaded" operating system on my CF card then my desktop iMac will shift its boot OS to the CF card. Can anyone speak to that concern?
"Install OS X Yosemite.app" is downloaded to your Applications folder, not to your Downloads folder. If you already downloaded it to install on your iMac, and didn't take steps to make a copy of the installer before running it, then the installer is gone, because it deletes itself after it completes the installation. It should still be possible to download it again, however, from the Purchases section in the App Store.
You don't want or need to install an OS on the flash drive in order to install Yosemite on a different computer: you want to a bootable installer on the flash drive. You can use DiskmakerX to create a bootable installer on a USB flash drive.
BTW it doesn't matter if your computer boots from another drive on which you have just installed an OS. It's normal, and finishes the installation process. You can switch boot drives anytime you want using Startup Disk in System Preferences.
The App Store strikes again. Just tried to re-download the Yosemite installer from a Yosemite drive, and it does not work. Clicking on "continue" results in nothing. The App Store is an even bigger mess than iTunes these days.
Mac Pro: in this case I was booted from a 10.10.2 drive. Could the problem have been that I had the Installer app stored? It wasn't in the Applications folder, but perhaps that doesn't matter. I was just trying to see if re-downloading would work, based on the problem the OP described. If I were to boot from an earlier OS and try again, I think that it would download OK. Not sure if that's an option for the OP.
A different thought: Is Yosemite the original OS version on the iMac you are trying to use to download it? If so, you can't use it for a different Mac as the originally installed OS license is for that machine only.
If you're installing to a new drive you may need to navigate during the installation to "Disk Utility". Be mindful as you select your new drive and format it with at least 1 partition by selecting the drop down menu. Also, click Options and make sure "GUID" is selected. Finally, choose a name that you like for your partition ("Untitled" is boring). Everything on the target disk will be erased, so make sure to target your new drive.
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
Three managed machines so far have tried installing Yosemite through the App Store and are giving me the Apple message "This Copy of the Install OS X Yosemite application is damaged, and can't be used to install OS X. Tried deleting it and redownloading but no luck. Any one else running into this? Any other ideas?
Are your systems configured to only allow applications from the App Store or identified developers? I found this link online suggesting to allow app installs from anywhere, which is weird since Yosemite is obviously from an identified developer.
I'm actually having issues with that as well but that may be because my JSS is at 9.22 so I don't want to correlate the two together. I can upload it fine, and Admin pulls the ESD out but when trying to run it it unfortunately doesn't run.
At the same time, using a custom image may not be what you're looking for because you may not want to overwrite the target drive. In our environment, we have desktop support folks that image lab computers once a year, so we use the custom image approach to overwrite the image from the previous year and we stay an OS X version behind. Labs are currently running Mavericks and next year will run Yosemite.
I ran into a similar issue, but with the latest version of the Casper software. I had to clear the extended attributes then I could get the application to launch properly. I'm not sure if that would help in your case. It's worth a try I guess. Check out the knowledge base article at =59
So within my installer log this is what is shown when running the Yosemite installer. The confusing like is "Macintosh HD is not recognized as install media?" I've tried repairing permissions and verifying the disk and all seems fine.
I had this problem and figured it out: there was a "BaseSystem.dmg" and some other hidden installation files at the root of the drive. These were leftover from a previous failed attempted upgrade to Yosemite. Deleting those files solved the problem.
In case anyone has this problem and find's this thread... Symptom that OS installer (El Capitan in my case) is damaged (not a 'verified' issue) and installer log says "Macintosh HD is not recognized as install media?"
I had this issue and deleted /BaseSystem.dmg and /BaseSystem.chunklist (both hidden) from 2 machines having this issue (both machines on 10.9.5, if that makes a difference), one of the machines also had the /OS X Install Data/ as maxbehr mentioned. After those were deleted the installer ran fine.

First download the OS X 10.10 Yosemite installer from the Mac App Store in the Purchases section (you may need to hold alt/option while selecting Purchases. Once it's downloaded, just quit the installer and set the downloaded file's name to InstallOSXYosemite.app (make sure only .app, not .app.app)
Now when we turn on Mac of my friend while pressing Alt , I can see the icon to install Yosemite. So I click on that and continue first steps like language without error, but after 2 or 3 steps I received error
Your installation file for Yosemite has had its digital certificate expire. Which means after a certain date it will no longer work. To work around this issue you open the Date & Time preferences pane, uncheck the box for "Set date & time automatically" & set the date back to just after the time Yosemite was initially released (October 16, 2014) then run the installer.
Well, it's actually a tricky one, since (sadly) that's a really unspecific error. It can be caused by many things. Though I guess it's not a filesystem error, since the installer booted up fine. So that's one reason out.
The first thing you should check (and add to your question please) is: Where did you get the installation file (ISO/DMG) from? Is it an official distribution from the App Store, or did it come from a third-party source (a pirating website maybe?). The reason that's important is that ol' uncle Apple are extremely annoying with their security. And I mean, extremely. No access to system files on iOS type of extremely. Now that's (as always :P) a problem here, since if the installation didn't come from a first-party source (aka the App Store), then it might not be properly codesigned (I explained a bit about codesigning below). So please edit your question so it specifies the source if the installation so I can help you further.
Another reason for your problem might just be that the installation is, as specified, corrupted. What does that mean? Well, a lot of times when burning files to a disk (e.g. burning an ISO to a USB drive), there might be a tiny error (maybe even a single corrupted byte) that will just ruin the structure of the whole file. Annoying, isn't it? This can be caused by many reasons. Maybe your file is bad, maybe your disk is bad, maybe your disk maker is bad (in which case I really suggest you try a personal favorite of mine called Rufus, which is also completely free, though sadly it's only available for Windows, so try to get your hands on one for a few minutes), and maybe it just happened randomly (yep, that happens. Bummer.). Go through option one, then if you have a legit, official copy of the installer, check your disk, then just try to burn the installer again. If it still doesn't work, switch to a different disk maker application.
So codesigning (code-signing) is pretty much a standard when it comes to Apple systems (macOS/OS X, iOS, etc.). It's something that is really awesome but also really annoying at the same time. From Wikipedia:
Code signing is the process of digitally signing executables and scripts to confirm the software author and guarantee that the code has not been altered or corrupted since it was signed. The process employs the use of a cryptographic hash to validate authenticity and integrity.
So, as I said, it's a pretty neat idea. It's basically a little encrypted string embedded in the software code, that approves that this is the official code, from the official developer, and that it should run just like it's supposed (assuming you meet the system requirements). You can think of it just like a signature: When you see the author's signature on a document, you can be sure that it's his, and that it's original and official. And just like a signature, it's unique and hard to fake. But the problem is that it causes a lot of trouble when a developer doesn't properly sign his code. For example, I tried to use GDB (the GNU Debugger) the other day, and it didn't work due to inappropriate codesigning. Even though, for the most part, it's up to the developer to be responsible for properly signing his code, it's still pretty important to understand what it is, at least in a general, basic level.
