Boot into Internet Recovery (Option Command R) and from the dropdown menu: Utilities>  Disk Utility> run the First Aid on your Macintosh HD (and the "Macintosh HD-Data" volume as well if Catalina/Big Sur) If errors are found and repaired, run again until no errors reported.


Disk Utility>View>Show All Devices The best sequence is —

• Volume level

• Container level

• Parent drive

Hi,

I did try that but nothings seems to work. It keeps telling me that OS X could not be installed, that no packages were eligible for install. See image below.
how can I install and older version if now I don’t have access to the apple store in my computer?
