No packages were eligible for install

I have an older, MacBook Pro (15-inch, Mid 2009) that I intend to give as a gift.

For security reasons, I decided that I was a good to format the drive and reinstall OS X El Capitan.

My first effort was thwarted by an error:

This item is temporarily unavailable.Try again later.

After reading Wiped drive, now can’t reinstall El Capitan from Recovery because the “item is temporarily unavailable”, I supplied a different set of icloud credentials, and the process continued.

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.

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?

To create a bootable USB drive, I needed the Install OS X El Capitan.app package.

Using my MBP 16", I used the Download OS X El Capitan link on Apple's support site to get the installer.

Unfortunately, running the InstallMacOSX.pkg package in the DMG failed:

This version of OS X 10.11 cannot be installed on this computer.

I 'found' a Install OS X El Capitan.app package and was able to create the bootable media.

Solution 1:

The accepted answer to the question (How can I download an older version of OS X/macOS?) that @nohillside suggested contained the ultimate solution--essentially the computer's date needed to be within a year of the OS' release.

Wikipedia's article on OS X El Capitan indicated that:

OS X El Capitan was released to end users on September 30, 2015, as a free upgrade through the Mac App Store.

Based on this knowledge, I changed the computer's system date to 2/1/2016 12:00:00 @ UTC using Terminal:

$ date -u 020100002016

Once the system's date was changed, the installation completed as desired.

Solution 2:

There is a link on the Apple website How to upgrade to OS X El Capitan that will download a file that can be used to create the Install OS X El Capitan application. 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.

This version of OS X 10.11 cannot be installed on this computer.

If you are trying to create a USB installation flash drive of use on another Mac computer, then you can still using the download file to create this installer. The instructions are given below.

The following steps can be used to create a USB installer for El Capitan.

This method was verified 2 days ago (4/17/20) by user Tak using Catalina on a MacBook Pro 2017 touchbar for use on iMac 2009 24”.

1. Use instructions on the Apple website How to upgrade to OS X El Capitan to download InstallMacOSX.dmg.

2. Erase a 16 GB or larger flash drive. Use the setting shown in the image below.

   

3. Use the Finder applicaition to open InstallMacOSX.dmg.

4. Enter the commands given below. A folder named El Capitan will be created on the desktop to hold temporary files.

   Note: The easiest way to enter the commands is to copy from this document and paste in the Terminal window.

   pkgutil --expand /Volumes/Install\ OS\ X/InstallMacOSX.pkg ~/Desktop/El\ Capitan
   diskutil eject Install\ OS\ X
   cd ~/Desktop/El\ Capitan
   hdiutil attach InstallMacOSX.pkg/InstallESD.dmg  -noverify -nobrowse -mountpoint /Volumes/esd
   sudo asr restore -source /Volumes/esd/BaseSystem.dmg -target /Volumes/MyVolume -noprompt -noverify -erase
   diskutil rename OS\ X\ Base\ System Install\ El\ Capitan
   rm /Volumes/Install\ El\ Capitan/System/Installation/Packages
   cp -rp /Volumes/esd/Packages /Volumes/Install\ El\ Capitan/System/Installation
   cp -rp /Volumes/esd/BaseSystem.chunklist /Volumes/Install\ El\ Capitan/
   cp -rp /Volumes/esd/BaseSystem.dmg /Volumes/Install\ El\ Capitan/
   hdiutil detach /Volumes/esd
   sudo bless --folder /Volumes/Install\ El\ Capitan/System/Library/CoreServices --label Install\ El\ Capitan
   cp /Volumes/Install\ El\ Capitan/Install\ OS\ X\ El\ Capitan.app/Contents/Resources/InstallAssistant.icns /Volumes/Install\ El\ Capitan/.VolumeIcon.icns
   diskutil eject Install\ El\ Capitan
   

    

5. Remove the flash drive

6. Drag the El Capitan folder from the desktop to the trash.
