No, your Mac is not possessed. And Yes, it’s trying to tell you something!
A looping three beeps in between three seconds during startup is your iMac’s way of telling you that the operating system you’re trying to boot into is incompatible with your Mac hardware.
In other words, the Snow Leopard disc you’re trying to boot from contains a version of Snow ...

The OS X equivalent of Windows services is Launchd. The OS X equivalent of services.msc on Windows is launchctl. The daemons managed by launchd can be on demand or can be triggered periodically (this is configurable in launchd.plist)
You can manage the daemons from the command line (from Terminal.app under /Applications/Utilities/) or by using a tool like ...

Plugging in headphones used to be the quick and dirty way to assure silence (back in the PPC hardware days).
Now, the self test startup chime still uses the internal speaker whether or not the headphone jack is in use, but the below trick will work on older macs. It is of use with new macs as long as you don't set your mac to reboot automatically and you ...

The checkboxes are not for disabling the application launch, but if checked, the application gets hidden as if you were pressing CMD+H. To disable it, select it in the list and click on the Minus-button beneath that list. By that you remove them. You can't just disable them with OS X tools.
To see a summary of all LaunchAgents and LaunchDaemons you can use ...

There are three official places I know of that unwanted items on startup are controlled:
1) Login preferences: if you want to delete an item, make sure you highlight it and then click "-" instead of just unchecking it. If it is unchecked, it will still start, it will just have a hidden windows.
2) "General" - make sure "Close windows when quitting an ...

It's based on the board ID in boot.efi. Depending on the model of computer, a black boot screen will be shown (introduced with Yosemite) instead of the older grey screen.
All these Macs and newer show the black boot screen:
MacBookPro10,1 (Retina, Mid 2012)
MacBookAir6,1 (Mid 2013)
iMac14,1 (Late 2013)
MacPro6,1 (Mid 2012)
Here's boot.efi from macOS 10.13....

For Snow Leopard and earlier machines download and install "StartupSound.prefPane" which will install a preference pane in system settings to allow you to adjust the startup volume and disable the startup sound:

Note that the above has mixed results in Lion. For Lion users the following is ...

It is in Preferences in V 10.0.43320 which I downloaded and installed yesterday.

Take a look at the following folders:
/Library/StartupItems
~/Library/StartupItems (if you have one)
/Library/LaunchDaemons
/Library/LaunchAgents
~/Library/LaunchAgents (if you have one)
You should be able to figure out what the StartupItems do by name, but Google them if you're curious.
You can figure out exactly what the Launch Daemons and Launch Agents ...

The graphics are telling you to turn on the Magic Mouse or Magic Trackpad associated with the MacBook. Have you ever connected one of these devices to it?
If you haven't, I have to wonder if the internal keyboard and trackpad are not connected somehow. What year is this MacBook? Is it still under warranty?
Unless you can boot to recovery and reinstall OS ...

It's not directly that Apple doesn't want you to do so, it's more that older OS versions are lacking the drivers etc. required for hardware which wasn't even known at the time the older OS was released. The most obvious example for this in your case is the Retina display (and the graphics driver required for it), there are probably a lot more parts including ...

So it would seem that if you only install the VPN client AnyConnect will not autostart.
I uninstalled AnyConnect (version 4.x) then reinstalled doing a custom install. I only installed VPN, I did not install:
Web Security
AMP Enabler
Diagnostics and Reporting Tool
Posture
ISE Posture
Now AnyConnect no longer auto starts (yeah!)
Makes sense I suppose as ...

The OS X boot process is chock full of little tasks in parallel and sequence, but it boils down to three major parts:
Gray Screen - Hardware governed / POST / EFI / locating a boot image.
Apple Logo on Gray Screen - System level OS X processes start.
Blue Screen - User level processes starting.
Since you haven't gotten to the blue screen - it's not ...

I'm not sure this is possible by default without holding down the ⌥ key at startup. You can make the Boot Camp partition always boot by selecting it in System Preferences → Startup Disk, but it sounds like this isn't what you want.
However, if you're not adverse to installing additional software, I think rEFIt may do what you need. The section on Getting ...

Open terminal, then:
sudo launchctl list | grep -i mysql
launchctl remove xxx.xxx.mysql
Where "xxx.xxx" is included in the output of the first command, for example "org.macports.mysql". The password for the "sudo" command is your own user account's password.
True, sudo isn't needed to "list" but because you already gave a sudo password for the first ...

A kernel panic is nothing more than a software crash. A bit like when an application quits for no apparent reason, except in this case, it brings down the entire system, since the kernel is the heart of the operating system. It looks like you weren't done with the installation, because it appears to be trying to continue the installation, but can't for some ...

Yes, LaunchAgents are only invoked when the user logs into a graphical session.
LaunchDaemons are typically launched when the system boots and are run outside of a specific user session.
The launchd manual page lists these folders with short descriptions:
Files
~/Library/LaunchAgents Per-user agents provided by the user.
/Library/LaunchAgents ...

Lingon (MAS link)
It provides a nice GUI for creating daemons/agents, without writing plist file by yourself. You can also use it to delete daemons/agents that you don't want.

Applications and Menu Bar items
Most of these can be easily configured in:
System Preferences → Users&Groups → Login Items
LaunchAgents and LaunchDaemons
Some applications are cannot be configured in the System Preferences (e.g. Sophos AV Scanner, HandsOff Firewall,...) It's best to configure them in their own application to assure that ...

Your question isn't (or at least wasn't) very specific. So there are multiple answers you may find helpful when trying to control annoying apps that open at log in:
Keyboard shortcut to disable items from starting up while logging in
Buttons to click to "officially" remove startup items
Places to look to actually remove startup items

You can set the default boot partition from the option-boot screen. Press the Control key while clicking the arrow beneath the drive, and that should do the trick.

Removing the following worked for me.

/Library/LaunchDaemons/com.cisco.anyconnect.gui.plist

No, you cannot assume that. This repeating startup chime with the three second pause between the three tones is an indicator that you are trying to boot your iMac from a non-supported operating system.
The 27" mid-2011 iMacs originally shipped with Mac OS X 10.6.6, and later shipped with Mac OS X 10.6.7. This iMac will not run from Mac OS X 10.6.5 or ...

From what you’ve said, I agree it should work fine.
My first guess would be to check the Startup Security Utility on the iMac Pro, a feature of the iMac Pro (and other T2 Security Chip enabled Macs) that allows Admin users the ability to enable/disable Secure Boot and also the option of allowing/disallowing External Boot. It’s the External Boot ...

Are you sure that it is apache you are seeing running. When you do the
ps aux|grep apache
You will see one process ( the shell process that is looking for the string apache)
A running apache server is not called apache it is called httpd, and you will see multiple instances of this (one parent daemon which in turn spawns workers). The apachectl is ...

I found the answer on AskDifferent's sister site Superuser.com:
Snow Leopard resets sound volume whenever I start my computer
In Macintosh HD / Library / Preferences / Audio there are two audio setting files. Delete them. Set your sound to the desired setting. Restart.
This solved my issue.

If your hard drive was clicking audibly, I'd say the actual hard drive has failed. Even if it did stop doing it as often, that's basically the Death Rattle as far as hard drives go.
The below is a copy-paste of an answer for how to get a Macbook booting again through a really base-level disk repair, but it doesn't always work. Give it a shot, but I really ...

I asked the Twitter user @launchderp:
@launchderp Arelaunchctl load and unload still safe to use, at least until 10.12 or whatever comes next?
c.f How do I use non-"legacy" launchctl commands to load and unload plists?
And @launchderp replied
@tjluoma Yeah they're still safe. Too many years of dependencies to break them.
While this ...
