Upgrade El Capitan

Hi. I have Mac Pro 2008. Today I tried to upgrade my system Yosemite 10.10.5 to new El Capitan. After restart my computer installation crashed. When I was trying start my system, on the display backround was something like code. Then system restarted many times, again and again, and installation doesn 't continue. Then I tried boot the system using recovery 10.11 (it was a second option on start up while holding alt during boot). Recovery process stopped at 80% and froze. I can 't install back Yosemite and El Capitan does 't work. What can I do?

Mac Pro (Early 2008), OS X Yosemite (10.10.5)

That card seems to be your problem with El Capitan, See:

I removed it. I can 't believe that it is ok now 🙂 Just removing the CalDigit. Thank YOU very much... I am going to celebrate this moment 😀

I e-mailed CalDigit and they sent me an uninstaller file to get rid of the driver. I ran it and it worked. El Capitan installed normally. Though the removal of the card seems to resolve the issue, they also recommended uninstalling the driver. You can reach them at support@caldigit.com

They also recommended, since this card is obsolete and they do not plan to update the driver, that I buy their newer card that also has eSATA ports on it, but the price is over $200! I have read that Sonnet cards cause issues also, so I don't know if there is a compatible card that will work on El Capitan.
