El Capitan Failed To Install
- El Capitan probably needs the most prep steps of any OS X system install. Specific steps for El Capitan in that support article, and you have to change your system clock before you begin the install of El Capitan. Boot to the Installer, at the menu screen, open the terminal, enter date, then press enter.
- OS X El Capitan is the twelfth major release of OS X for Mac computers. It was released on September 30, 2015. Some users have reported an issue where Mac refuses to finish booting after updating to OS X EL Capitan. If your Mac will not start up, stalls on a gray screen with an Apple logo, here is how you troubleshoot.
- Jan 03, 2016 Was trying to instal el capitan on my macbook, the installation starts and after a few minutes stops and a messaging saying the os x could'nt be install on the computer, please contact the software editor to get help. I called apple and they said they can't give me any tech support, i guess cause my computer is too 'old'.
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:
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.
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.
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.
Many Hackintosh users running Mac OS X Lion have been unable to login to the Mac App Store, instead receiving the error, 'Your device or computer could not be verified. Contact support for assistance.' The verification issue appears to have affected the several legitimate Macs as well, though on less wide of a scale. There is no single, definite solution to this issue, but several possible workarounds are available. Read past the break to find out how to fix the error.
There are several solutions to the login error.
1. Go to /Extra in your main hard drive and open the text file org.Chameleon.boot.plist with TextEdit. This is the configuration file for the Chimera bootloader (which UserDSDT uses). Add this string to the part of the file between <dict> and </dict>:
<key>EthernetBuiltIn</key>
<string>Yes</string>
Then reboot. If this doesn't solve the errors, proceed to the next solution.
2. Open org.Chameleon.boot.plist again. Add the following string:
<key>PCIRootUID</key>
El Capitan Could Not Be Installed On Your Computer
<string>1</string>
El Capitan Could Not Be Installed On Your Computer System
If this string is currently set to 0, change it to 1. Reboot.
3. If neither of the above solutions fix the issue, open the System Preferences app and go to the Network section. On the left-hand column in the Network section, select each of the items and remove it by clicking the minus sign on the bottom of the column.
Then, go to /Library/Preferences/SystemConfiguration in your main hard drive and delete NetworkInterfaces.plist. Or alternatively, drag it to the desktop (as a backup, in case things go wrong).

By removing all of the Network items in System Preferences and deleting NetworkInterfaces.plist, you have effectively reset the network configuration for Mac OS X. Reboot (you may have to reconfigure your internet connection afterwards).
