Mid-2012 cMBP startup sound?

[jbsmithmac]

I just got a mid-2012 15" cMBP. I noticed when starting up it seems to have a different chime than I'm used to. It's almost like the volume is up too high that it is making something vibrate.

It's not the SuperDrive noise.

Just wondering if this is normal on this model...it works fine, and if it is vibrating I don't know what it could be...nothing seems loose.

I only notice it because my mid-2009 doesn't sound the same.

Try a PRAM reset. This tends to fix issues when the Mac has no startup chime. So, maybe it works for you as well.

Good point I'll try that.

I reset the NVRAM, but in doing so I now think its completely part of the superdrive. I guess this superdrive just sounds different than my mid-2009 mbp does when it starts up.

It's more like a buzz than what I call the superdrive's "eye" moving into position (I assume it's checking to see if a cd is in there).
