Hi, I'm new to the forum .
I take this opportunity to greet all .
I write to you for advice.
I have an iMac 21.5 late 2015 took a month ago .
unfortunately I got it with the ' hard drives .
possessing a Samsung SSD 128Gb I took this case UASP :

The system works well , but I have a problem with the screen background .
I have two screens , and when yi reboot, the background changes .
you know what you can do ?
the system is El Captain.
Sometimes it comes back to default ,
sometimes a background that I had used previously .
