However, the sha1 hash did match any of the values at: -installer-checksums#mac-osx-installers-sha1-checksums6198647687 bytes, openssl sha1 InstallESD.dmg --> 732f873cbcf38d9e544e659d2429bd4444416cdaI am pretty sure the file is legit (since I downloaded it directly from Apple Support), so I edited the "mkosxinstallusb.sh" script and added it to the approved list--> see the line starting with "supported_checksums="...", and just added it to the end before the last closing quote)Also, make sure your USB thumb drive is completely empty before you start the script. In my case, I actually plugged it into the mac and formatted it with Disk Utility to "OS X Extended (Journaled)" (GUID Partition table) before I started. (I had tried it once before with a partially occupied USB drive, and it ran out of space before it could finish). I am not sure how much difference it made to format it withDisk Utility, but that is what worked for me!I then ran "sudo bash mkosxinstallusb.sh /dev/sdX "InstallESD.dmg", and the script took care of the rest.Finally, I could boot up the Mac while holding "option/alt" and my USB drive appeared as a bootable device! 17 minutes later I can startup OSX!
I may go ahead and re-download the installer and create a new bootable USB using "createinstallmedia", just in case there was a problem with the image I used, but at least now I can boot up the computer!

I'm thinking of using this method to revert back to an older os due to my mac slowing down with Sierra. Will I be able to install just Yosemite or el capitan? Without installing previous os upgrades? This way I can have a fresh mac book.
With OS X El Capitan, Apple has built on many of the changes that were brought on by Yosemite. And as with previous OS X versions dating back to OS X 10.7, El Capitan is only available for install via download from the App Store.
I am trying to erase the hard drive of my Mac Retina but the security system does not allow me to open disk image: 2this is an app downloaded from a non identifier developer. It does not allow me to add an exceptionEvenmore, the computer does not open after a reboot if any key is pressed.I am crazy. It seems like a virus is trying to prevent its dead.
Whatever the issue was, we need to download the install files with theinstaller. Open the installer and let it run until the download finishes. Ifthe app asks you to reboot, quit it at this point. If it never asks, you canstill find a way to get files out (after a failed install, they should not beremoved).
EI Capitan (10.11) is the last release of OS X. After it, the OS versions are under a name called macOS. From our observation, there are still many people using EI Capitan on their Mac as some of the apps are not running on macOS. Hence, if your Mac was something wrong with it and you need to create a bootable installation media to reinstall OS X EI Capitan on your Mac. Honestly speaking, it is a tough process for EI Capitan and you might receive errors when using the dmg file downloaded from Apple website.
Warning: The download file hosted on Apple.com (InstallMacOSX.dmg) will only work on Mac platform. For creating installation media on Windows, please use the above link instead. The dmg file provided by Apple contains a .pkg file in DMG archive, which will result failure if you are using it on a PC.
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.
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.
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.
That just indicates that you still have an older copy of the installer squirreled away somewhere on your boot drive. The App Store is very good at knowing this, so you might want to spend a bit of time trying to locate and trash it. That may well be why the one you downloaded was then moved to trash.
Apple has no advice on how to do this, nor have I seen any here or elsewhere. Pre-Sierra systems cannot be re-downloaded from the App Store with the new certificate. (But I got a full installer.) Maybe you managed to create a bootable installer yourself from the new El Capitan?
Anyone having luck with downloading the full 6GB Mojave installer from the App Store? On one machine I only get a 22MB stub installer. On another machine I was able to download the full 6GB version but the installer app reports to be damaged. I re-downloaded it a few more times with the same results.
I had exactly the same thing happen to me despite downloading a brand new Mojave installer. Then I realized, the problem is launching the installer off an external HDD. As soon as I moved it back onto my internal boot SSD, it launched just fine.
With much hyped Windows 10 has become ill-famed due to the privacy concerns all over the world and now people are now almost tilting towards Mac OS. Mac OS X El Capitan 10.11.6 is the latest offering which will further enhance user experience. You can also download Mac OS X El Capitan 10.11.1 InstallESD DMG.
The command-line installation of macOS would come as savvy mainly for the system administrators. You really do not require a bootable installer to upgrade macOS or reinstalling the operating system, It only will be useful when you have multiple computers lying around and you need to download and use the installer each time.
