Reinstall just system files?

[Ifti]

I have a problem with Notes not opening - just crashes and closes within a few seconds.

If I Command+R on boot, and restore the OS, will it just overwrite system files??
All my apps/settings and data etc should remain intact???

I'll take a backup beforehand of course, but just wanted to be sure of what to expect!

Thanks

Yes and yes.

You should be making backups regularly, of course.

If by restoring you mean going to Recovery mode->Reinstall OS - yes, this way you'll reinstall system-related settings/apps only. You'd loose current data by erasing volumes, disks in Disk Utility or by restoring from Time Machine (it may replace the current version of a file with the one from backup)

All done, thanks for the responses
