So your mac is not booting into Mac OS X Yosemite, you will have to reinstall using the Apple Recovery Servers.
The certificates for several of Apples OS's expired in October 2019, Apple have been very poor at getting these updated on
their Recovery Servers with valid certificates.
This may be the problem you are experiencing.
Try this workaround, we are going to set the time and date on your mac to a date previous to the expiry date of the certificates.
Connect your mac to your router via cable, not WiFi
Boot to your Recovery HD, click on Utilities in the menubar select Terminal.
Make sure WiFi is switched off, it can reset the date back to today.
Enter a new date, for example or just copy and paste
sudo date -u 011421002017
press Return
enter your password
press Return
If Terminal returns an error saying sudo : command not found, then try again without sudo.
just enter
date -u 011421002017
press Return
You won't be prompted for a Password if you did not need to use sudo
Once the date has changed you can quit Terminal.
Now try downloading the OS.
Click on Install OS X, press Continue.
If this works then when the OS is installed and booted up you can Open System Preferences> Date & Time
and reset the time back to today.
Hello Rouge mim again, I followed the steps you gave, I put the date on terminal and the date changed, I quit the terminal. When I go to install the OS X I get this information an error occurred while preparing the installation. Try running this application again.
but don’t go father. It doesn’t work. I have tried so many times.
Hello Rouge, last night I followed your instructions change the date, use the cable and disconnected the wi- fi but did not allowed me to complete the installation OS X capitan , some kind errors came several times , what I did, I disconnected the internet cable turned off the computer for one day. Now I tried with wi-fi and it worked allowed me to install the a OS X capitan. And I followed the instructions to complete the installation.
I really don’t know what upended but thanks for your help Rouge now I will explore my new software.
