This Answer is indeed the only option I've found. The installer auto-launches, but you can quit the installer before it does anything. Ah, it wasn't obvious from your question that you were trying to virtualise - which would have changed the tone of my answer, but not the actual content.
I don't have a paid developer account, so user 's answer would not be one open to me. When I filter that list for "os x mountain lion" I get no offers to download the entire OS installer. I see five downloads for updates not original installers. I looked through the list and found base installers for all OS versions up to However, like you, I could not find base installers for I'm guessing that is because starting with Click the Download button on the Sierra page.
After download is complete, the installer opens automatically. Click Continue and follow the onscreen instructions. Graham Miln Doesn't contain a download link for Sierra, just a link to the app store page. Yes, of which you can click the download button.
I was going to write that "that doesn't work anymore", because it doesn't on my iMac Pro. This is wonderful. I spent an hour running around the app store and fighting Apple's useless support designed to make sure you can't reach out to anyone trying to find a way to get Sierra which I don't want but need for a FCPX update, High Sierra is too big a mess to consider.
If you really want to contact someone at Apple this might help - apple. If your device is released in the year , you can download the OSX that was current back then, i. But you can't download Lion, Snow Leopard etc. Solved for me by logging out of app store then, on log in, having to sign a new user agreement. Good point, Jim, thanks! We'll add that to the article. Have you rebooted after deleting everything? Did you empty trash? This article, and this method just helped me to re-dl the Yosemite installer.
I had the exact symptoms you list. I'm not a huge fan of using Terminal. The temporary solution to set system date to 1 Feb via terminal scares me.
If Terminal must be used, what is the Terminal command to set the date back to the real time. This is the problem I have with posters on various forums. They give the command on how to do something but fail to give the command to undo what you just did. That's meant as a "oh, drat! The proper solution is to get a new version of the installer. Don't be scared of Terminal in this case.
The command you are running can only affect the time, as long as you don't type anything other than the "date" command, you are at exactly zero risk of unintentionally performing other operations that could harm your system. Thanks Adam, but my question remains: Can you set the date and time via system preferences prior to doing the install and have it work.
Probably assuming automatic time setting is turned off , but if you're in a position where you can set up your installation environment in advance, you should just get a new installer so it's not an issue. If you're thinking that far ahead, you'd be better off downloading the newer installer with the current certificate. But say you're booting from a USB drive because your Mac won't start up or you've put in a new hard drive, then Terminal is your only option.
Yes, I understand the best practice is to re-download the new installers. Give your readers a heads up and save them some time. If you have previously downloaded and saved the installer on a different partition or external hard drive, unmount them before downloading. If you don't, the download does not appear in Applications because somehow it knows you have it stored elsewhere. Just lost 2 hours as a result of this. Indeed - that's why we recommend deleting all old installers before starting.
Besides, you might need the disk space for the new ones! I've tweaked the article to note that external drives might have copies. Again, those should be deleted - just ejected the drive is a start, but you don't want those old versions sitting around confusing things in the future. Having previously downloaded OS X installers on mounted external disks didn't cause any problems for me at all.
I was still able to re-download the El Capitan, Yosemite and Mavericks installers. Instead of ending up in the Applications folder, the newly-downloaded installers simply replaced the older ones stored on my external drive—saving me the trouble of copying the new installers to the external drive after download. I like to keep different version installers — For my scenario, redownloading won't work, will it?
You only get the last version of the OS installer. Unfortunately, I think you're right - you can only get the latest version from Apple, so there's no way to get a previous minor version installer as far as I know. You might look into the command line installer tool, as mentioned in the article. I don't know if that can be used for OS X as a whole, but it might be worth some research.
I hate it when those who pirate software have it easier then those of us who bought the software legitimately. I feel certain that this problem that breaks older software purchased via the Apple App store doesn't affect pirates.
The Purchased list only goes back to Jan 7, I've got installer flash drives with all the OS versions made already. Can I just replace the Installer with the new version, or do I have to reformat and install via Terminal again?
I'm guessing you can just replace the installer, but a test to make sure it works would be prudent, so you're certain it will work in an emergency situation. So wouldn't you think Apple would put a different version number on the installers with the upgraded certificate so people would know?
Interestingly, two of the new ones had the same version number as the installer on my flash drives but the new Yosemite was version 1. The 'new' installer had an older version number! Yeesh, Apple, if this is certificate issue is a real problem. Thanks for the heads up. Now I cannot find that link and as you have seen, it says I cannot upgrade to El Capitan.
However, I've never really been sure my machine IS compatible with El Capitan because my model number is not listed on the compatible list. It's like my model doesn't exist. My 15" 2. All those listed as compatible are s and s. I may have an old Mac that I could download El Capitan to, but am unsure it will work on this machine. Jan 27, AM. Communities Get Support.
