Photobooth suddenly started automatically launching at startup

After the most recent Leopard update. How do I turn it off? I hate seeing my face first thing in the morning. Thanks.

Patrick
Right click on the PhotoBooth icon in the Dock. Is 'Open At Login' Selected?

TS1717 I cannot get iTunes to automatically launch at startup in Windows 7. I need it to do this so my Apple TV 'finds' my Music Library, which is stored on an external hard-drive, connected to my Windows 7 PC.

I cannot get iTunes to automatically launch at startup in Windows 7. I need it to do this so my Apple TV 'finds' my Music Library, which is stored on an external hard-drive, connected to my Windows 7 PC. Anyone know how I do this? I cannot seem to find anything on Google, which is surprising.
iTunes helper launches OK, but not iTunes itself. Am I being dim?
Thanks

The iTunes application should be installed on the system drive. You may need to repair iTunes to fix that error regarding a missing .exe.
To organize your library properly see Make a split library portable.
If you don't have a working version of the library that can be transformed into a portable shape I have tools and techniques that can repair the broken links.

IPhoto starts automatically with computer startup

I recently installed a new hard drive in my MacBook Pro. After the install, now every time I start the computer, iPhoto starts automatically. Is there a setting that I can change to stop this. It's not a big problem, just a little annoying.

try right clicking on the iPhoto icon in the dock and making sure that the option to "Open at login" is not set

Why is Firefox (Mac) launching on startup?

I am running MacOS 10.7.5. It seems like around the time I upgraded to Firefox 18, it started to launch upon Startup. I have verified that my Preferences Login items does not include Firefox. My general System preferences are set not to restore windows on Startup.

* Control-click on the Firefox Dock icon and uncheck 'Open at Login'
* Click Accounts (in the System row of the System Preferences window)
** Click the Login Items tab
** Click on Firefox in the list
** Click the Minus (-) button

App. automatically launches, but not listed in accounts/startup items

I have a pesky application which automatically launches on start-up, yet it's not listed in accounts/startup items. It's called Microtek scanner finder. I seem to remember it started doing it when I originally got the scanner and installed software, and although it's always niggled I didn't mind when I was using the scanner. However, I'm not using the scanner anymore so want to be rid of it in my dock. Where the heck is it coming from? I don't want to chuck all the software as there may be an occasion where I need to scan a transparency, when I'll need to get the old scanner down from the loft... any ideas? It definitely launches as there is a little black triangle beneath the icon in the dock. If I quit it, it disappears but is back there again on another start-up grrrrr.

Hi, Kathykate. I have a similar Epson Scanner Monitor application that starts up each time I restart my computer. (Mine does appear in Sys Prefs > Accounts > my account > Startup Items, so I could delete it from there if I wanted to.) It runs all the time in the background, using a tiny amount of CPU and memory, and it has no user interface at all: If I quit it, nothing visibly changes, and if I open it again, there's no visible sign that it's open (including no icon in the dock for it). Its only function is to detect my Epson Scanner when I plug it in and turn it on. I ignore it the rest of the time, because whether it's running or not has no impact whatsoever on anything I do. I suggest that you take the same attitude toward your Microtek app.

How do i disable automatic launch of open programs on startup

how do i disable automatic launch of open programs on startup

It's the Resume feature.
When choosing Restart, Sleep or Shutdown there is a checkbox you can uncheck to prevent the apps from launching.
Also in System Preferences > General there is a hard-to-find checkbox under "Number of recent items" you can turn off.
Also, you can hold the shift key to disable resume on a one time basis.
You can turn off Resume globally by going to ~/Library/Saved Application State and deleting that folder.
(note that the User Library is hidden - one way to get there is to go to your Finder "Go" menu hold the option key to choose "Library")
To turn off autosave and versions globally
If you're experiencing slow opening apps or windows since upgrading to ML... as I have... and you don't want your OS to automatically save your TextEdit files, etc. then simply disable Autosave and Versions via Terminal.
If you don't want autosave or resume you can copy & paste this command into Terminal at the prompt...
defaults write -g ApplePersistence -bool no
Press return
Now reboot.
The reverse would be "yes".

How to disable automatic launch of WIE in startup configuration with no options to do so?

Thinkpad T400 2764CTO running Windows 7 Home Premium 64
PC only 2 weeks old, very little on it, but getting slower and slower. Finally found the configuration for the startup menu and disabled several things I knew I didn't want at startup. One problem that I can't seem to figure out, is how to disable Windows Internet Explorer from being launched at startup? I have tried disabling every Microsoft option, and it still launches. Is there a specific Lenovo option [that does not obviously have anything to to with WIE] in the startup menu that, if disabled, will stop the WIE browser from being launched? How do I know which options are not safe to disable when attempting to slim down startup configuration for faster/more reliable performance?
Thanks,
Ann

Either I *completely* misread your instructions; that fix is major overkill for what I was trying to do; that fix does not apply to my problem; that fix is only for XP or Vista and not W7; or my PC is already so messed up (despite clean hardware diagnostics, no viruses, no malware, and it is only 2 weeks old), that it performed unexpected and unwanted actions when trying to use the Windows features on/off program control panel options.
Opened Control Panel, went to Programs, and finally found the option on the left for turning Windows features on and off. Unchecked the box for IE8, which required a restart. The restart time was 4-5 times longer than usual, even when launching superfluous programs from the startup menu, since it had to "reconfigure Windows." After restarting, WIE did not automatically launch, and its toolbar icon was gone too. Tried to turn it back on like you said, which also required a restart, which didn't make sense to me, since I expected the browser to launch again following another extra long restart once the box was re-selected. Although, surprisingly, it didn't, so for a moment thought it had somehow worked. Then I realized that my WIE icon was still missing from the toolbar, so there was no way to launch it even if I wanted to. Went back into the Control panel and checked every Windows feature box possible; another extra-long restart; still no toolbar icon for WIE. Had to go into the computer files to find WIE so that I could create a desktop shortcut icon so I could manually launch the browser from that. However, when I clicked on the shortcut, it went into a browser setup mode, as if it was being set up for the first time. Finished setup and tried to go to a webpage, but kept getting a connection error.
Diagnosed it, and it said that the Local Area Connection had no valid IP address. Waited on hold with Mediacom for a hour before being disconnected, trying to find out what the IP address was and where to re-enter it, since unchecking the IE8 box in the Windows features part of the Control Panel, doesn't just temporarily disable the function, but apparently actually deletes the toolbar icon, as well as the IP address. Took several more attempts over several hours to get ahold of Mediacom reset the signal to get the IP address back and get back online. So that really does not seem like a viable solution for trying to save time and resources by removing something from the startup menu, if it just quadruples startup time, deletes WIE toolbar icon and IP address permanently, requires creating a desktop shortcut, and then requires several more hours on phone with ISP for signal reset to get the IP address back. Would have been much faster and done less apparent damage than just going ahead and letting it launch at startup and then just closing it. *sigh*
I know that just having an icon in the toolbar does not mean that that particular program will launch at startup, as I have several others that have toolbar icons that I have been able to uncheck in the startup menu, so I can use the toolbar icons to launch each program manually. There just doesn't seem to be any program active in the startup menu that would be launching the browser, and still concerned about unchecking something necessary in startup that could screw it up even more.
Is there any way to get my toolbar WIE icon back without a full system restore, so that I have less shortcut clutter on my desktop?

Start program automatically at Windows startup

Have a couple of programs that currently require manual start-up after Windows 2012 r2 Essential reboot. Would like to find out how to have the programs start automatically as part of the boot up process.

Hi IstMe,
Based on your description, I understand that you want to start some programs automatically when the server restart. If anything I misunderstand, please don't hesitate to let me know.
Please open Task Scheduler and create a task. Then click Triggers tab and configure
Begin the task: At startup. Then also click Actions tab, configure
Action: Start a program and add that programs which you want to start when server start.
Task Scheduler Overview
In addition, you can also consider
computer startup scripts. Use a computer startup script to run programs with unattended parameters. Regarding to detailed script, you can post requirement in the
Script Forum. I believe we will get a better assistance there.
If any update, please feel free to let me know.
Best regards,
Justin Gu

I downloaded Safari for Windows Public Beta Seed 31A15 from the Apple Developer Connection (http://developer.apple.com) and it fixed my problem crashing on startup. I'm running Windows XP Pro but it may work for you on Vista.
You have to setup an account or use your existing Apple ID to log in to the Developer Connection.

Hi, sorry this is so basic, but how do I stop certain applications starting automatically on startup?

sorry this is so basic but how do I stop certain applications starting automatically on startup?

Is this for a computer model or an iDevice model? If the former you've posted in the wrong forum. But here's the answer.
Open General preferences in System Preferences. There are two options you can check that affect this behavior:
Check the boxes you thing you prefer. When you next shutdown the computer you should be asked in a dialog about reopening applications on restart. Select the option to not reopen.

How to tell "ituneshelper" not to start automatically at startup

To stop iTuneshelper from starting automatically:
1-- Go to System Preferences
2-- Click Accounts
3-- click Login Items tab. This shows all the items that are automatically loaded when you log into your account.
4-- In that list you will hopefully see an item called "iTunesHelper." Apparently this little program has the job of making it so that iTunes can watch for iPods getting plugged in and so on.
5-- to remove iTunesHelper from this list, click on it to select it, and then click the "-" (minus" button) at the bottom of the list.
6-- You just removed that startup item. If you later find that you have problems connecting to your ipod or for some reason you want that startup item back, then you can delete and then re-install iTunes by downloading it from itunes.apple.com (don't worry, it will find your music folder when you reinstall) OR, more simply, you can go to your applications, find the iTunes application, right click it, choose "view package contents," go into Contents folder, then go into Resources folder, then find iTunesHelper.app and drag ituneshelper.app onto that list on the Login Items window that we mention in step 3. That will bring it back onto that list. Then restart your mac and you will see ituneshelper running automatically again.

This setting is here: In Safari push 'cmd'+',' (comma) or click on Safari/Settings in the menu bar...
(sry for german UI, but I think you see where to go )

I am using an early 2008 MacBook Pro and am having issues with it deleting text on its own (in word, emails, etc.). As I am typing it all of a sudden starts deleting and I can't stop it. What can I do?

I am using an early 2008 MacBook Pro and am having issues with it deleting text on its own (in word, emails, etc.). As I am typing it all of a sudden starts deleting and I can't stop it. This happened once before and it was due to a buldging battery pressing on the track pad. I checked the battery and it appears to be fine. What can I do?

Please read this whole message before doing anything.
This procedure is a test, not a solution. Don’t be disappointed when you find that nothing has changed after you complete it.
Step 1
The purpose of this step is to determine whether the problem is localized to your user account.
Enable guest logins* and log in as Guest. For instructions, launch the System Preferences application, select Help from the menu bar, and enter “Set up guest users” (without the quotes) in the search box. Don't use the Safari-only “Guest User” login created by “Find My Mac.”
While logged in as Guest, you won’t have access to any of your personal files or settings. Applications will behave as if you were running them for the first time. Don’t be alarmed by this; it’s normal. If you need any passwords or other personal data in order to complete the test, memorize, print, or write them down before you begin.
Test while logged in as Guest. Same problem?
After testing, log out of the guest account and, in your own account, disable it if you wish. Any files you created in the guest account will be deleted automatically when you log out of it.
*Note: If you’ve activated “Find My Mac” or FileVault, then you can’t enable the Guest account. The “Guest User” login created by “Find My Mac” is not the same. Create a new account in which to test, and delete it, including its home folder, after testing.
Step 2
The purpose of this step is to determine whether the problem is caused by third-party system modifications that load automatically at startup or login.
Disconnect all wired peripherals except those needed for the test, and remove all aftermarket expansion cards. Boot in safe mode* and log in to the account with the problem. The instructions provided by Apple are as follows:
Shut down your computer, wait 30 seconds, and then hold down the shift key while pressing the power button.
When you see the gray Apple logo, release the shift key.
If you are prompted to log in, type your password, and then hold down the shift key again as you click Log in.
Safe mode is much slower to boot and run than normal, and some things won’t work at all, including wireless networking on certain Macs. The next normal boot may also be somewhat slow.
The login screen appears even if you usually log in automatically. You must know your login password in order to log in. If you’ve forgotten the password, you will need to reset it before you begin.
*Note: If FileVault is enabled, or if a firmware password is set, or if the boot volume is a software RAID, you can’t boot in safe mode.
Test while in safe mode. Same problem?
After testing, reboot as usual (i.e., not in safe mode) and verify that you still have the problem. Post the results of steps 1 and 2.

On start up i just get a grey screen with the apple logo-this has suddenly started happenin. Please help?

on start up i just get a grey screen with the apple logo-this has suddenly started happenin. Please help?

Take each of these steps that you haven't already tried. Stop when the problem is resolved.
To restart an unresponsive computer, press and hold the power button for a few seconds until the power shuts off, then release, wait a few more seconds, and press it again briefly.
Step 1
The first step in dealing with a startup failure is to secure the data. If you want to preserve the contents of the startup drive, and you don't already have at least one current backup, you must try to back up now, before you do anything else. It may or may not be possible. If you don't care about the data that has changed since the last backup, you can skip this step.
There are several ways to back up a Mac that is unable to start. You need an external hard drive to hold the backup data.
a. Start up from the Recovery partition, or from a local Time Machine backup volume (option key at startup.) When the OS X Utilities screen appears, launch Disk Utility and follow the instructions in this support article, under “Instructions for backing up to an external hard disk via Disk Utility.” The article refers to starting up from a DVD, but the procedure in Recovery mode is the same. You don't need a DVD if you're running OS X 10.7 or later.
b. If Step 1a fails because of disk errors, and no other Mac is available, then you may be able to salvage some of your files by copying them in the Finder. If you already have an external drive with OS X installed, start up from it. Otherwise, if you have Internet access, follow the instructions on this page to prepare the external drive and install OS X on it. You'll use the Recovery installer, rather than downloading it from the App Store.
c. If you have access to a working Mac, and both it and the non-working Mac have FireWire or Thunderbolt ports, start the non-working Mac in target disk mode. Use the working Mac to copy the data to another drive. This technique won't work with USB, Ethernet, Wi-Fi, or Bluetooth.
d. If the internal drive of the non-working Mac is user-replaceable, remove it and mount it in an external enclosure or drive dock. Use another Mac to copy the data.
Step 2
If the startup process stops at a blank gray screen with no Apple logo or spinning "daisy wheel," then the startup volume may be full. If you had previously seen warnings of low disk space, this is almost certainly the case. You might be able to start up in safe mode even though you can't start up normally. Otherwise, start up from an external drive, or else use the technique in Step 1b, 1c, or 1d to mount the internal drive and delete some files. According to Apple documentation, you need at least 9 GB of available space on the startup volume (as shown in the Finder Info window) for normal operation.
Step 3
Sometimes a startup failure can be resolved by resetting the NVRAM.
Step 4
If a desktop Mac hangs at a plain gray screen with a movable cursor, the keyboard may not be recognized. Press and hold the button on the side of an Apple wireless keyboard to make it discoverable. If need be, replace or recharge the batteries. If you're using a USB keyboard connected to a hub, connect it to a built-in port.
Step 5
If there's a built-in optical drive, a disc may be stuck in it. Follow these instructions to eject it.
Step 6
Press and hold the power button until the power shuts off. Disconnect all wired peripherals except those needed to start up, and remove all aftermarket expansion cards. Use a different keyboard and/or mouse, if those devices are wired. If you can start up now, one of the devices you disconnected, or a combination of them, is causing the problem. Finding out which one is a process of elimination.
Step 7
If you've started from an external storage device, make sure that the internal startup volume is selected in the Startup Disk pane of System Preferences.
Start up in safe mode. Note: If FileVault is enabled in OS X 10.9 or earlier, or if a firmware password is set, or if the startup volume is a software RAID, you can’t do this. Post for further instructions.
Safe mode is much slower to start and run than normal, and some things won’t work at all, including wireless networking on certain Macs.
The login screen appears even if you usually log in automatically. You must know the login password in order to log in. If you’ve forgotten the password, you will need to reset it before you begin.
When you start up in safe mode, it's normal to see a dark gray progress bar on a light gray background. If the progress bar gets stuck for more than a few minutes, or if the system shuts down automatically while the progress bar is displayed, the startup volume is corrupt and the drive is probably malfunctioning. In that case, go to Step 11. If you ever have another problem with the drive, replace it immediately.
If you can start and log in in safe mode, empty the Trash, and then open the Finder Info window on the startup volume ("Macintosh HD," unless you gave it a different name.) Check that you have at least 9 GB of available space, as shown in the window. If you don't, copy as many files as necessary to another volume (not another folder on the same volume) and delete the originals. Deletion isn't complete until you empty the Trash again. Do this until the available space is more than 9 GB. Then restart as usual (i.e., not in safe mode.)
If the startup process hangs again, the problem is likely caused by a third-party system modification that you installed. Post for further instructions.
Step 8
Launch Disk Utility in Recovery mode (see Step 1.) Select the startup volume, then run Repair Disk. If any problems are found, repeat until clear. If Disk Utility reports that the volume can't be repaired, the drive has malfunctioned and should be replaced. You might choose to tolerate one such malfunction in the life of the drive. In that case, erase the volume and restore from a backup. If the same thing ever happens again, replace the drive immediately.
This is one of the rare situations in which you should also run Repair Permissions, ignoring the false warnings it may produce. Look for the line "Permissions repair complete" at the end of the output. Then restart as usual.
Step 9
If the startup device is an aftermarket SSD, it may need a firmware update and/or a forced "garbage collection." Instructions for doing this with a Crucial-branded SSD were posted here. Some of those instructions may apply to other brands of SSD, but you should check with the vendor's tech support.
Step 10
Reinstall the OS. If the Mac was upgraded from an older version of OS X, you’ll need the Apple ID and password you used to upgrade.
Step 11
Do as in Step 9, but this time erase the startup volume in Disk Utility before installing. The system should automatically restart into the Setup Assistant. Follow the prompts to transfer the data from a Time Machine or other backup.
Step 12
This step applies only to models that have a logic-board ("PRAM") battery: all Mac Pro's and some others (not current models.) Both desktop and portable Macs used to have such a battery. The logic-board battery, if there is one, is separate from the main battery of a portable. A dead logic-board battery can cause a startup failure. Typically the failure will be preceded by loss of the settings for the startup disk and system clock. See the user manual for replacement instructions. You may have to take the machine to a service provider to have the battery replaced.
Step 13
If you get this far, you're probably dealing with a hardware fault. Make a "Genius" appointment at an Apple Store, or go to another authorized service provider.

PSE automatically launches on Mac OS

All of a sudden whenever I turn on or log on to my iMac OS X, PSE 6.0 automatically launches. It never used to do this. The icon is on my dock and just starts bouncing and launching and it's driving me crazy. There is no place I can find in PSE preferences to turn this off. Help!

There is nothing at all in PSE that could do this, but I bet it's the Adobe Updater that's causing it: look in the dock a minute or so after PSE launches. Do you see a white rectangle there? That's the adobe updater. To stop it, since you probably already clicked on Later or something sometime to make it do this, you'll need to let it run, then go to the Updater window and you'll see a Preferences button. Click that and turn off auto updating. It's just a nuisance and the only thing it ever successfully updates is Adobe Reader, not PSE.
If that's not it, somehow PSE got into your startup items folder. System Preferences>User Accounts>Login Items.
