These thieves are back with us once again with their poorly constructed, ridiculously overpriced software. Anything AlphaOmega sells is a GIANT RIP-OFF! Don't be the fool who sends them to the bank!!!

This pricing has to be an April Fool's joke. Nobody could possibly...

The startup chime isn't just some kind of acoustic window dressing. It's a diagnostic tool (if certain things go wrong with your Mac it changes). Someday a repairman may need to hear your Mac's chime. You're a fool if you mute or ochange it.

According to tinker tool system, disabling the startup chime on 10.7 and newer is no longer supported by the software.I would suggest a freel alternative that should work for anyone is to hit mute on your keyboard before restarting, this will mute the chime and just unmute when the system is restarted. I found this out by accent when I frogot to unmute my sound and I restarted and wondered where the sound went on startup. I have to say though, unless i'm unaware of it, I'm suprised that someone hasn't come upt with a way to modify the firmware to insert a custom sound. Unless the chime is in the firmware that can't be flashed, then that's understable. Just some thoughts, hope the tip helps someone who wasn't aware of it. Note, powerP macs may not work with this rule I believe their sound management was different from intel based macs.

To the best of my knowledge, nobody has ever figured out where the startup chime lives, let alone a way to "touch" it.

Absolutley hilarious! They say a fool and his money are easily parted, etc. Then again, when I see that there have already been over 1600 downloads of this from Macupdate (which indicates that the devs may have pilfered at least $32,000 out of this app?), maybe I’m the fool. I wouldn’t have the balls to actually target the nievety of uneducated Mac users so brazenly, but these dev do. Hell, I have this scary feeling in the pit of my stomach that some small part of me actually admires how unashamed the devs are. I shall now humour myself and have a look at their website to see what other goodies they have in store for us….

have you ever heard of $1000 iPhone app called "I Am Rich" ..?? just to give you an idea what kind of people out there.


Luckily the download counter is not the same as their sales counter. I would think their sales counter is awfully low since none of their software does anything useful.

Is this real? As John Sawyer pointed out, this must be some sort of joke. 20$ is a complete rip-off. Get TinkerTool System for 14$ instead. It allows to disable the start-up chime and much more for only 14$ or try one of the free alternatives.

I'm guessing this utility and its price are a deliberate joke on the part of the often-criticized programmer, to annoy people--note also the absurd version number: 4.2.-2147483648d-2147483648

A rip off. Charging this much for slapping a badly written front end on somebody else's work is a disgrace. AlphaOmega software are a disgrace.

LMAO... MacPilot has this function, does a few hundreds other things and costs even less than this. AlphaOmega releases should be allowed only on the first of April.

Sorry, but I couldn't help leaving a comment when I saw the price tag on this--it is absolutely ridiculous! $20 for a tiny utility that performs a single function? No one should, under any circumstances, pay for this "app." As other posters have pointed out, there are free or low-cost alternatives that will do the same thing and in some cases much more. If you want to spend $20 on a system tweaking utility, get MacPilot which can mute the startup chime along with hundreds of other tweaks. AlphaOmega Software is perhaps the biggest running joke in the Mac software community. Their apps are good for a laugh and nothing else. I'm actually shocked that the company still exists, but clearly someone is buying this crap...

It looks like the only change between the previous version and this version, v2.4, of Startup Crime Stopper is the addition of an Italian localization (thereby giving the developer more publicity, once again, for his grossly overpriced app). What's next for version 2.5, Latvian localization? I can hardly wait. By the way, the previous commenter's suggestion that you can go for Tinkertool System instead of this app is right on. TinkerTool System is around $10 and is one of the excellent full featured maintenance apps with a plethora of great, useful features, including one to mute your Mac's startup chime. Now, if AlphaOmegaSoftware could come up with something really innovative and brilliant like TinkerTool System(but I won't hold my breath, sigh...), I just might change my otherwise low and contemptuous opinion of that software company.
