Install El Capitan from the installation disk. Create the macOS X 10.11.6 El Capitan Install Disk from official sources. As the hdiutil tool is proprietary, we do not have the choice to use an macOS to create the ISO file. I have used macOS 10.11 to create this ISO. The El Capitan installer has essentially bricked my iMac. And since I can't mount the filesystem, I can no longer create a backup from it. My drive is a Seagate 2TB SSHD hybrid that I installed in April 2014 and is still under warranty.
Installing El Capiton on an old Mac Book Pro today, I received the error:
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.
I checked Apple’s support Matrix (it is a very old macbook pro) at https://support.apple.com/kb/SP728?locale=en_GB and it was listed as supported. Probability and statistics degroot solutions manual. Skyrim add dragon souls command.
After lots of Googling and investigation, I discovered that the date and time were not set to current, the macbook thought it was year 2000.
You can easily reset the time and date by following the steps below:
- Click Utilities on the menu bar
- Select Terminal
- Type date
- Confirm the date is wrong
- Type date 062112422016 (example: June 21st 12:42 2016)
- Exit terminal
- Click Restart
Once the Date and time are configured you will be able to install OS X.
Easy fix, for a ridiculous error!
When trying to upgrade from OS X 10.6.8 Snow Leopard to OS X 10.11.6 El Capitan, I repeatedly encountered a frustrating 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.'
My end goal was to install macOS 10.13 High Sierra. I read online that one must upgrade to OS X 10.11 before upgrading to macOS 10.13 if one is starting from OS X 10.6. This upgrade route did not work for me no matter how many solutions I attempted. I eventually found a solution to this frustrating problem which I'll share below, but before I do that, I'd like to share what did NOT work for me to hopefully help others avoid unnecessary frustration and wasted time:
Solution attempts that did NOT work for me:
El Capitan Could Not Be Installed In Computer
I tried changing the time to the correct present time and to a past time when the installer certificates may have still been valid (mid-2016). The upgrade problem persisted either way.
Manually setting the date and time via the Terminal (see above link) to an earlier date is worth trying because it has worked for some people. Try this time: 1010101015
2) Erasing my internal hard drive using Disk Utility in Internet Recovery Mode
All this did was remove my data, but the persistent 'OS X could not be installed..' problem remained.
3) Booting from an external hard drive that was formatted to act as an installer for OS X 10.11
4) Booting in the Internet Recovery Mode option to install the version closest to the operating system that came with my Mac (Shift+Option+Command+R).
My Mac came with Snow Leopard, which is not available to download, so it attempted to install Lion, but wasn't able to do so because I had not purchased it with my Apple ID.
Here's the upgrade route that DID work for me:
1) I purchased OS X 10.7 Lion with my Apple ID and downloaded it via the Mac App Store on another Mac (so it would be in my App Store download history)
2) I booted in the Internet Recovery Mode option to install the version closest to the operating system that came with my Mac by holding down Shift+Option+Command+R while my MacBook was restarting.
3) I selected 'Reinstall Mac OS X' in the 'Mac OS X Utilities' window that appeared when Internet Recovery Mode fully booted up.
4) When prompted, I entered my Apple ID information that was used to purchase and download OS X 10.7 Lion and allowed the OS X upgrade to proceed to completion. I then had a fresh version of OS X 10.7 Lion installed on my Mac.
5) The next step was to upgrade from OS X 10.7 Lion to macOS 10.12 Sierra using these steps.
6) Once macOS 10.12 Sierra was fully installed, I upgraded to macOS 10.13 High Sierra using these steps.
Mac Os El Capitan Install
My MacBook Pro is now successfully running macOS 10.13.6 High Sierra.
Basically, what worked for me was circumnavigating the suggested route of installing OS X 10.11 before installing macOS 10.13. Instead, I followed this upgrade route: 10.6 to 10.7, then 10.12 to 10.13.
El Capitan Failed To Install
I thought it may be helpful to share what worked for me in case someone else out there is trying to upgrade from OS X 10.6 Snow Leopard to macOS 10.13 High Sierra and encountering the issue I encountered. Please feel free to ask me any questions about this and I will do my best to help.
