Should You Apologise to The Audience?
For example, if you had planned a PowerPoint presentation to include a sound-clip or a voice-over (tricky thing to do; be careful!), when you get to that part of the presentation and your clip fails to play, should you apologise to the audience about it, or just move on to the next slide as if nothing happened?
This can go two ways.
FIRST, if the audience did not know about the clip and there is no way for them to know that something is missing, then you should simply get on with your presentation and leave out that "Oh, I'm sorry the sound clip is not coming up".
Why? Because by apologising for your error, you are actually drawing the audience's attention to something that they didn't even notice about your presentation!
SECOND, on the other hand, if the failure of the clip leaves a big hole in the continuity of your presentation (depending on what function it was meant to perform), then you should consider tendering an apology. That is the polite thing to do.
There are other instances when things could go wrong during a presentation. Remember Murphy's Law? It says: "If Anything Can Go Wrong, It Will". So don't ever be too sure nothing unexpected will happen (even your laptop could crash on the morning of an all-important presentation).
The simple advise to follow is this: withhold your apology if you're sure the audience cannot notice the flaw/error/omission, or whatever. You'd only be calling their attention to your (apparently) poor preparation and then your precious reputation as an expert/professional might come under heavy gun fire!
But, what happens if you completely mis-judge the audience's perception and fail to apologise for something that even a blind man in the audience could see is missing or very wrong with your presentation (the classical elephant in the room)? I hate to even think of it. God help you!

How Do You Make The Right Decision?
One thing you can do for yourself to raise the odds that your on-the-spot decision to apologise, or not to apologise, is the right one, is to know your material down to the bones! This is one of the reasons why you must avoid giving a presentation on behalf of somebody else, unless you were actively involved in the process that created or developed the presentation (at least, to a reasonable extent). Remember, it is YOUR own reputation that will come under fire if things go wrong, not the reputation of the colleague or friend (or boss) that you're standing in for.
Full "cover-to-cover" knowledge of your presentation content, slides and equipment will guide you in making the right decision and avoid the pitfalls of excessive, unnecessary, apologies.
