- El Capitan Cannot Be Verified Full
- I am trying to upgrade an older iMac (2008) from OS 10.6.8 to El Capitan for a disabled client who really needs to use a Mac instead of a PC!
- EveryMac says it can handle El Capitan if I upgrade RAM. It has 4GB now.
- I have an Installer file from my own Mac (always keep them when I upgrade). I made a bootable flash installer that mounts and seems to have the proper files, but it won't show up on either Mac on restart holding option key; nor in the Startup Disk list. So, I figured writing to the flash drive must have failed.
- I partitioned an external hard drive and redid this:
'sudo /Applications/Install OS X El Capitan.app/Contents/Resources/createinstallmedia --volume /Volumes/MyVolume --applicationpath /Applications/Install OS X El Capitan.app'
- It seems to work (again) in Finder AND it shows up as a boot option on restart (holding option key), but when I select Install OS X I get an error that the installer cannot be verified. I can't get it to work.
- So, I figured my installer must have gone bad, even though I successfully upgraded my own Mac with it, and have since upgraded mine to Sierra.
- Using the App Store I can get to El Capitan, but it will not allow me to download it on my Mac because the system is too new, and I don't want to download it to the old Mac because I want to use an external drive to do a clean install; not an upgrade on the old one.
- Any advice?

If the issue is with your Computer or a Laptop you should try using Restoro which can scan the repositories and replace corrupt and missing files. This works in most cases, where the issue is originated due to a system corruption.

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>
<string>1</string>
If this string is currently set to 0, change it to 1. Reboot.
