I downloaded the 'app' from the Store on the iMac and restarted to begin the installation process. During the install I receive the following message: OS X could not be installed on your computer. No packages were eligible for install. Contact the software manufacturer for assistance. Quit the installer to restart your computer and try again.

But it can quickly become frustrating if, instead of being presented with a brand new Mac, ready to use, you see an error message like “macOS could not be installed on your computer.”. Eventually, however, the installation failed with a different message: No packages were eligible for install. Contact the software manufacturer for assistance. Quit the installed to restart your computer and try again. Continue to keep these buttons held until you hear the Mac startup chime twice. After the second chime, let go of the buttons and let your Mac restart as normal. No user data will be lost in this process. Resetting your PRAM will not only fix this particular OS X install issue, but it can also fix network issues, sound issues, and display issues. No packages were eligible for install. Contact the software manufacturer for assistance. Quit the installed to restart your computer and try again. I tried using 'Internet Recovery' (Option+Command+R) and a bootable USB drive that contained El Capitan, both of which ultimately failed with the same message. Is there a way to get this to work?

The upgrade install is the easiest way to upgrade your Mac to macOS Sierra. This method preserves all of your current user data, documents, and apps while upgrading the existing operating system on your Mac's startup drive to macOS Sierra. The advantage is that once the upgrade is complete, your Mac is. If you were hoping to revert back to High Sierra, or install an older OS X on a partition or VM, you will not be able to get the old installer if you are running Mojave. No packages were eligible for install. Contact the software manufacturer for assistance. Quit the installed to restart your computer and try again. However, if the model Mac is too new to allow the installation for El Capitan, then message given below will occur when trying to create the Install OS X El Capitan application.

How to prepare your Mac for the clean install

Check macOS 10.13 High Sierra compatibility

Before you can enjoy all the new goodies from macOS High Sierra, you must answer the question: can your Mac run macOS High Sierra? Nervous? Don’t be, as the specs look quite promising. How promising? Well, you’ll be able to upgrade to High Sierra even if you own a Mac as old as 2009. Sure, the hardware might cause you some slight drawbacks and refuse to run all the features, but overall you should be able to enjoy the big refinements. Things look even brighter when it comes to newer version of Macs, which should support the new operating system without any problem whatsoever.

Go for a system cleanup and fast backup

Mac High Sierra No Packages Were Eligible For Installation

The first step towards a clean install, is a drive format. But act with caution! Before you do anything drastic, make sure you cleanup and backup your Mac to keep your important files.

Start with a system clean-up. Okay, that’s actually an euphemism for: delete everything you don’t need, throw away any duplicates and erase all the useless data.

Don’t know how to do that exactly? Check out How to clean up your Mac for a detailed and easy way to perform a thorough cleaning.

There are going to be some important files you will want to keep. Be it files, documents, photos, movies or other apps, you’ll want to create a backup for them. Where? That’s up to you. You can choose either iCloud or any external storage device with enough space.

Now it’s time to wipe your Mac clean. But you did perform a Mac backup, right? Good! Then you can format the drive! Here’s how:

Go to Applications > Utilities and click on Disk Utility. From here, select the drive and hit Erase, as you select Mac OS Extended (Journaled) as the format type.

Before you start new life with the new macOS, get equipped with a couple of backup and maintenance tools. They will save you should something goes wrong. The good solutions are Get Backup Pro or Disk Drill.
And the last thing before we start. A new OS needs a fresh Mac, so trim down the fat on your system. Use an app like CleanMyMac X to remove all system junk, large hidden files, and old apps' leftovers.

A step by step guide to clean install macOS High Sierra

1. How to download macOS High Sierra

The new macOS High Sierra has long been available for the developers only, but now is public and available in Mac App Store.

Here is the link to download it directly: macappstores://itunes.apple.com/app/id1246284741

Make sure you download the macOS High Sierra Installer to the /Applications folder and leave its default name.

2. Create a macOS High Sierra Bootable USB Drive

Mac High Sierra No Packages Were Eligible For Install

A clean install wouldn’t be possible without creating a macOS High Sierra Bootable USB drive. So let’s go ahead and create one! Find an 8 GB USB stick and make sure it is formatted as GUID Partition Map and Mac OS Extended (Journaled). To check if it is, launch the Disk Utility application. It’s from here that you’ll also be able to make the needed changes, if the case.

Once you’ve done this, plug in the USB into your Mac and launch Terminal. There are 2 options for doing this: you either go to Launchpad or you can choose the Spotlight search. Next, write the following command, letter by letter:

sudo /Applications/Install macOS High Sierra.app/Contents/Resources/createinstallmedia --volume /Volumes/USB --applicationpath /Applications/Install macOS High Sierra.app --nointeraction

Ready? Great! Hit return, enter your admin password when prompted and them simply go along with the instructions to complete the process. In about 15 to 30 minutes you’ll have your bootable USB and you’ll be one step closer to macOS High Sierra’s world of new features.

3. Clean Install macOS High Sierra from USB Bootable Drive

You’ve got this far. Now, it’s time to actually hit the install button and leverage all the steps you’ve completed. Take your bootable USB and connect it to your Mac. To continue, restart your Mac while pressing the Option Key.

This will open the Startup Manager from where you’ll be able to start the clean install. Proceed by erasing your hard drive from Disk Utility. Once you’ve deleted this, go back to the main menu and hit install. The steps will be prompted to you on screen, and you’ll easily be able to complete the installation. Voila! Now enjoy macOS High Sierra!

Here in Belgium schools are locked down due to #coronavirus. With the school of my two oldest kids now switching to remote teaching, I took the time to set up my old MacBook Pro (model late 2008) for my two oldest kids to use. That didn’t go without any hiccups though: the OS X installer refused to install …

The MacBook I had shelved a long time ago was still running OS X Mavericks. As that version was quite showing its age – and didn’t seem to support 2FA for use with my Apple ID – I decided to upgrade it to El Capitan, of which I still had the installer app lying around. I opened up the installer, it prepared some things, and nicely asked to reboot. Upon reboot the installer was ready to install, but when actually starting it greeted me with this error message:

OS X could not be installed on your computer.

No packages were eligible for install. Contact the software manufacturer for assistance. Quit the installer to restart your computer and try again.

Uhoh! Restarting the MacBook, as suggested, did nothing: the installer kept showing that same error message. Trying to change the startup disk to get back into Mavericks (by pressing ⌥+R upon starting the machine) also didn’t help, as I could only launch the installer and a recovery partition. Yes, the machine was actually stuck in a loop where it would only launch the installer and the installer wouldn’t install.

~

With a Google Search Coupon in hand I found that the installer refuses service because the certificate it was signed with (some time back in 2015, when El Capitan was released) got expired by now.

Thankfully one can easily circumvent this expiration by simply changing the date of your system. You can do this before starting the installer, or through a Terminal if the installer is already loaded (as it was in my case).

1. In the OS X Installer, choose Utilities > Terminal.
2. Enter date 020101012016 and press Enter.
3. Quit Terminal and reboot to retry the installation.

💡 In this particular Terminal you’re running as root, so no need for sudo here 😉

Here the date is being set to Feb 1st, 2016. You might need to tweak the date a bit depending on when you downloaded the installer originally (as it might be signed with a different certificate). Be sure to set it no earlier than the release date of the OS X version you’re trying to install.

💡 The syntax for the date command is a bit counterintuitive. Choosing your own date will require some puzzling from your end:

~

Later versions of OS X, such as High Sierra, have become a bit smarter: they give you the warning upfront – when first launching the Installer.app – instead of after having prepared your disk for installation.

I don't do this for profit but a small one-time donation would surely put a smile on my face. Thanks!
