Q: An error occurred while installing Mac OS X
My MacAir 13" Mid 2012 had the El Capitan latest version 10.11.5 installed. Suddenly a morning a few days ago it starting misbehaving, getting stuck, and when rebooting the system it appeared a screen with a folder in the center with a ¨?¨in the center. Sometimes it managed to reboot the system to get to the desktop screen but getting stuck again and again. I rebooted the system in Safe Mode, deleted some login items, suspecting an item might be troubling the starting process, but it did not help.
My decision was to restore the system installing the El Capital again after formatting the hard disk, but now the problem was another: The download was good, but when installing just a few minutes before finishing an error appeared on the screen saying: An Error Occurred While Installing Mac OS X. And I tried, tried several times until I decided to take it to the authorized technical service, but they could only installed the El Capitan 10.11.1 arguing that they it was the only version they could manage to installed after several trials in installing the El Capitan 10.11.5
So, they did not solve the problem fully, cause now it seems I am not able to have the latest version of El Capitan, and now I am not sure if I run the restoration via Time Machine because the problem could show again.
1- Somebody know how to fix this, installing the latest version without having the Error message?
2. If not, what happens if I restore from Time Machine on this version of El Capitan 10.11.1 if I had the backup from a newer version 10.11.5
MacBook Air, Mac OS X (10.0.x), Lion

It turned out that the SSD hard disk was damaged in a small portion. No any apple diagnostic was able to detect that, but using a third party diagnostic showed that it had some uncorrected errors and the disk might failed soon, which obviously was happening now. Nevertheless, the disk at the end allowed me to install the 10.11.5 then run the update to 10.11.6, I discovered that when I installed Dropbox, all the system crashed again, apparently because Dropbox reads and writes using all parts of the HD. At least that is my reasoning. I had to buy a new SSD (and of course I took advantage to do the upgrade in space to 240gb)
