I have just done a fresh install of High Sierra on my iMac (21.5-inch, Late 2009) but halfway through my mac emitted a very loud and long beep, it restarted and shut down twice before continuing with the install.
It has just finished installing and everything seems to be working, does anyone know what could have caused this, and is it something i should be concerned about, i have done many installs of various mac osx and have never had this happen before.
