Introduction

Now that the final version of macOS 10.14 Mojave, has been released, many people have installed the new OS on their Hackintosh.

Several users, however, have reported the following error during installation.

“macOS could not be installed on your computer. The installer resources were not found. Quit the installer to restart your computer and try again.”

This happens regardless of whether you’re performing an upgrade or a clean install, and whether the drive you’re installing to is formatted as APFS or HFS+.

So, what’s the solution?

If you’re installing to a SATA drive

After some investigation, and some trial and error, the only solution seems to be to physically disconnect all the drives in your computer, apart from the drive onto which you’re actually installing the new OS. Physically disconnecting the SATA cables from all additional drives before running the installer allows the install to proceed.

In my case, I had a total of four SATA drives connected internally – two SSD’s and two HDD’s. With the drives connected, I got the error message to the left, every time, without fail, after the first reboot.

After disconnecting the drives and leaving only the single SSD where the OS was being installed connected, the installation went through without problems.

Once the OS has been installed, you can safely reconnected all of the SATA cables.

If you’re installing to an NVMe drive

If you’re attempting to install Mojave to a NVMe drive, like the Samsung 960 EVO or the Samsung 970 EVO, the error seems to occur regardless of whether additional drives are connected or not.

In this case, your only solution is to physically remove the NVMe drive, install Mojave to a SATA drive and then use Carbon Copy Cloner to clone the SATA drive to the NVMe drive after installation.

There may well be a better solution in the future, but for the time being, at least, this seems to be the only way to get past the error.

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.

Macos Could Not Be Installed

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.

Did this help you out? Like what you see?
Thank me with a coffee.

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