Problem reinstalling OS X Lion

Ok, so my MacBook Air becomes unresponsive when logging in, and I decided to reinstall OS X Lion. When running the installer from OS X Recovery, it gave the error message "An error occurred while preparing the installation. Try running this application again."

Checking in the log revealed the following error:

Can not connect to /var/run/systemkeychaincheck.socket: No such file or directory

Error!! Error Domain=NSURLErrorDomain Code=-1202 "UNTRUSTED_CERT_TITLE" UserInfo=0x1086bec80 {NSLocalizedDescription=UNTRUSTED_CERT_TITLE, NSLocalizedFailureReason=UNTRUSTED

The rest of the line is cutted off. Does anyone know what went wrong and how to fix it?

Thanks,

lhk

MacBook Air (13-INCH, MID 2011), Mac OS X (10.7.2)

I am installing a different hdd in a Macbook Pro to give to friend. After highest security (7 pass) erase on the original disk, then install of MacOS Sierra I decided to go ahead and upgrade it to a larger used hdd. So after installing the drive and using internet recovery to perform the erase/highest security, I kept getting the error: "UNTRUSTED_CERT_TITLE", when trying to reinstall MacOS... (-_Q) #facepalm

I am SO thankful to @snevas for the information:

"The certificate couldn't be verified because a wrong system time (mine was reset to 31/12/2000). You can check by executing `date` from the terminal (is located under the utilities).

To fix the date execute: `date MMDDHHMMYY` (M=Month, D=Day, H=Hour in 24-hour notation, M=Minute and Y=last 2 digits of year).

After this you can install Mac OS..."

You are so right @snevas!!! I am installing Mac OS Sierra on that machine as I type my elated response!!!

Blessings!!!! 🙂 😀 🙂

Excellent, thanks so much, worked great! Found your answer almost immediately after encountering the problem. Saved me a bunch of frustration re-installing Sierra. The date had been reset to about 1 year earlier due to replacing the internal SSD which involves disconnecting the battery for a few minutes. I wonder why? Maybe there is a dedicated clock battery that is dying? It's a 2011 MacBook Air.

Thank you for the instructions, the additional detail and screenshot. Remember to use " at the beginning and end of the date code (I didn't at first). So telieved to have my Mac working again! :)
