Psst2.1.1

Been using this since it was released, on multiple Macs and versions of OS X, and its always worked for me. I'm currently using it on a mid-'11 iMac i5 with Yosemite and it's still going. I set to the quietest setting, but not silent, so I can still tell if the machine is restarting properly but it won't wake up the whole house. Perfect.

I have tested Psst on my 2.8 GHz Intel Core 2 Duo iMac running OS X 10.8.5 Mountain Lion and it works perfectly, either completely muting or reducing the volume of the startup chime.

I Love this little utility app - I've used it for 6 years on a G4 Powerbook, a G4 Digital Audio, a MDD G4, and a G5 dual 2.0 (all running Tiger 10.4.11). Also worked on the G5 & the Powerbook under Leopard 10.5.6. After years of "too loud" startup chimes waking the kids at 3 AM [and freaking ME out as well!], I finally have the perfect solution! The app is 'persistent', so set it and forget it! (unless you want to make changes, then just relaunch & move the slider volume). One of my all-time favorite apps!! Does EXACTLY what it needs to, and DOESN'T mess with anything else! I've never had any app or sys process conflict with it.

I downloaded v.2.1.1 for my wife's new iMac. I setted near to zero the volume and tried to reboot without submitting an answer to developer's question. The system told me Psst prevented to relaunch. I tried to quit it, but it refused. I was forced to a forced quit. So I relaunced and I answered it didn't work. Then I CLOSED the submitting window and, surprise, relauncing again I discovered it works. After many attempts I can confirm that it works flawlessly. The problem is all in that window! It's impossible to submit before trying. It should have a short time persistence then automatically disappear. Add iMac 2,66 GHz Intel Core 2 Duo with OsX 10.5.5 to compatible Mac list.

i upgraded to iLife '08 and then my sound stopped working... internal speakers were not listed in my sound preferences. during the iLife install the machine deleted some of my system caches. i uninstalled Psst & the sound came back... could have been a coincidence but if someone else has the same combination maybe removing may be worth a try. i didn't try to re-install it.

Started using Psst 2.1 in June 07 - worked fine for a couple months. Then stopped working. Trashed it and downloaded again, and again it worked fine till yesterday. Trashed it and downloaded 2.1.1. So far, no joy. Intel iMac 1.83 GHz, OS/X 10.4.10

This software is great. Thanks a lot to his autor. Works fine on a MBP and iMacG5.

Another freeware to consider, if Psst does not work, is StartupSound.prefPane 1.1b1 http://www.macupdate.com/info.php/id/16425 It has worked flawlessly both of my G5 Tower and MacBook Pro.

Something very annoying about the intel Macs is that they don't remember the volume setting between restarts, and they *still* chime if headphones are plugged in. With Psst, you can set the volume so it's always at the level you want it when you restart your Mac, and you can lower the chime volume or mute it altogether. Small memory footprint, invisible, Psst is great!

Should work with 10.3.9? Sadly, it doesn't. Nor does the uninstaller, you have to take it out manually. Very disappointing - especially since it would be a useful thing to have, and the only alternative (Startup sound) doesn't work either.

Psst! works flawlessly. I installed it without problems a few months ago, set the chime volume level to it's lowest setting, and haven't given it another thought. Works perfectly every time. It's simple and reliable.

Everytime i try and run the program i get an error about not being able to name something in the login items or something... Running PowerBook G4 OSX 10.4.3 Whats up man? Cant rate it as i cant get it to work... Would love to use this software but....

Whyatt, 2.0.3 should fix that!

I started up the app and got the message "Where is PsstDaemon?" and a list of apps. The PsstDaemon wheren't within the list of apps, so I force quit the app, showed package contents of it and then restarted the application. It opened up just fine, and I set the startup volume. Haven't yet tried if it works, but this is definetily a bug in any case. Using 10.4.3...

If you have troubles with Psst! 2.0.1 you might want to take a look at this: http://mistatree.org/Freeware/PsstTroubles.html

Use your imagination... Starting up your Mac without a chime would serve as the best alarm clock of all: music; whatever music you like... Without the chime, you hear nothing but the song that you added to your startup items after your Mac has started up using the automatic Start Up feature in the Energy Saver control panel. Not useless, not at all...

Hmmm, Startup Chime Stopper has NEVER worked on my mac, and PSST! doesn't either... but at least I didn't pay for PSST! ..maybe I'll try this other program!

I would use StartupSoundPrefPane to adjust the sound. http://www.macupdate.com/info.php/id/16425

Dont Work on iMac & Quicksilver! : ((

This may be a bad idea, considering that the chime can also indicate that something's wrong with your system (if the sound changes, I believe). Using something like StartupSound.prefPane (http://www.macupdate.com/info.php/id/16425) to change the volume of the chime (and yes, silence it completely, if that's what you want) might also be an option.
