CD drive always opens on start up

Hi
I have a G4 Sawtooth OS 9.2.1. With an M7803 Mac keyboard. Works fine, except that the CD drive ALWAYS opens when I boot up, and I have to close it manually. Happens with or without extensions on/off ?

Hi, GoneToLunch -
Welcome to Apple's Discussions.
That model Mac (as well as many others) is hardwired with a hardware startup instruction - if the mouse button is held down from the beginning of booting, it instructs the Mac to eject all removable media; effectively it instructs all drives capable of ejecting to do so regardless of whether there is anything in the drive.
If an attached USB device happens to send a signal which the Mac interprets as a mouse-down signal, that commad is sent to all such drives.
The culprit can be most anything USB, including any device, hub, or even the extension cable furnished with some G4's for use with the keyboard. Items which have been reported most often as causing this are an iMate adapter, a dongle, and a digitizing tablet.
The only way to find out which item is causing it is to test by trial and error - disconnect all USB stuff except keyboard and mouse, then test; add one or two usual items back in, test again. When the problem recurs, you'll know it was the last item reconnected.
Sometimes the offender can be prevented from causing this problem by isolating it, via a self-powered USB hub. Sometimes a reconfiguration of the USB connection scheme will do it, such as by using a different port for the offender. Sometimes nothing will help, and it becomes an inconvenience that must be tolerated if the device is needed.
Relatedly, perhaps, this Apple KBase article recommends that not much at all be connected to a keyboard's ports -

Finder window always opens on start up.

Whether I am starting up or restarting, when I login then a finder window always opens on the desktop. Why? Is this now normal behavior for the finder? Is there a way to stop it?

do you have anything at all in your login items? sometimes other apps will open a finder window like that. see this thread for example

Mounted drive is opening during start up.

Can any of you help me with the following problem? I have mounted a drive and you can have it automatically start up without having to connect them manually every time. However, you can avoid with a hide button that it opens in a screen every time you startup. Hide the selection does not work. Every time I boot the disk opens in a screen. Does anyone know what the problem is and how I can fix this? Thank you.

Howdy Scapin,
It sounds like you are using the Hide option in the Login Items to try to keep mounted servers from opening.
Check out
OS X Yosemite: Open items automatically when you log in
If you don’t want an item’s windows to be visible after login, select Hide.
Note: Hide does not apply to servers, which always appear in the Finder after login.
You might want to try closing the server window before shutting down.
Best,
Nubz

External drive always opens embarrassing folder when mounted

This ought to make a few of you laugh...
Every time I plug in my 120Gb external WD drive, the finder opens up straight to the Videos>****> folder (less than 1% of the drive, I swear!) This is potentially embarrassing, and I have already narrowly escaped situations with my family and workmates. I don't know how to change it! I don't remember having this problem before I installed Leopard.
Any ideas?
thanks,
B

According to Google, FAT32 uses a 16-bit time field and has a resolution of 2 seconds.
Mac OS X has a resolution of at least 1 second, and possibily even finer granularity depending on the HZ clock frequence used by the kernel for managing the clock, where HZ=100 would be 10 milliseconds resolution
sysctl kern.clockrate
So it is very possible that img99, img100, img103, img104 all have odd time values, and when they are rounded down on the FAT32 file system, they always look older than the originals on Mac OS X.
It is a theory.
Have you experimented using a say another directory on Mac OS X to see if going HFS+ to HFS+ works as expected? Have you tried using a Linux ext2/ext3, etc... file system (which should have at least 1 second precision as well).
OK, using Disk Utility, I've created a FAT32 disk image, and copied a file with a modification time containing an odd number of seconds. Then I compaired the original time against the FAT32 time
stat tmp.1
234881026 61128371 -rw-r--r-- 1 harris harris 0 43
"May 22 21:07:47 2010"
"May 22 21:07:27 2010" <<<--- Modified time
"May 22 21:07:27 2010"
"Dec 26 21:57:18 2009"
4096 8 0 tmp.1
stat /Volumes/FAT32/tmp.1
234881031 10 -rwxrwxrwx 1 harris harris 0 43
"May 22 00:00:00 2010"
"May 22 21:07:26 2010" <<<--- Modified time
"May 22 21:07:26 2010"
"May 22 21:07:46 2010"
131072 4 0 /Volumes/FAT32/tmp.1
Notice the modify time on the original has 27 seconds, but the FAT32 copy of the file has 26.

Terminal window always opening at start-up?

My apologies if this is not the most appropriate place to post my questions.
Recently, I've been getting frequent messages that my start up disk is almost full. I've emptied the trash and will soon be burning some of my iPhoto albums onto disk. I'm very hopeful that will help. (Any other suggestions would be greatly appreciated.)
However, the bigger reason for my post is that the terminal window has started opening automatically every time I start up.
This is what the window says:
Terminal 80 x 24
-X print help on non-standard options
-ea[:<packagename>...|:<classname>]
-enableassertions[:<packagename>...|:<classname>]
enable assertions
-da[:<packagename>...|:<classname>]
-disableassertions[:<packagename>...|:<classname>]
disable assertions
-esa | -enablesystemassertions
enable system assertions
-dsa | -disablesystemassertions
disable system assertions
-agentlib:<libname>[=<options>]
load native agent library <libname>, e.g. -agentlib:hprof
see also, -agentlib:jdwp=help and -agentlib:hprof=help
-agentpath:<pathname>[=<options>]
load native agent library by full pathname
-javaagent:<jarpath>[=<options>]
load Java programming language agent, see java.lang.instrument
-splash:<imagepath>
show splash screen with specified image
logout
[Process completed]
I have NO idea what any of this means. Would someone please tell me what's going on with my Macbook and what to do about it? Thank you so much.

back on your disk problem - does it seem that the bulk of your space is within your user account?
If so, then carry on moving what you can.
it's worth quickly checking that the numbers make sense, and your shortage isn't due some file you can't see.

Installed evernote web clipper and now evernote windows always open upon start up

Have installed the Evernote webclipper and now when I open Firefox it opens my home page but then immediately opens at least one if not more Evernote windows. I have uninstalled and reinstalled Firefox. I have disabled and reinstalled the web clipper to no avail.
The problem started after I had to reinstall Firefox and the search engine Delta Search came attached to that. Delta appears to be gone but I can't seem to resolve this. If I disable the web cliper add on Fire Fox works fine. Previously I had no problem. I also have downloaded the Evernote web clipper to my Chrome browser and it works fine. Any suggestions would be most appreciated.

''' ... I had to reinstall Firefox and the search engine Delta Search came attached to that ... '''
Where did you download Firefox from? <br />
When you download Firefox directly from Mozilla you don't that Delta Search stuff or other unwanted programs or add-ons.
Please download Firefox from here: <br />

Then uninstall what you now have and install the official version.
Then see if that issue with Web Clipper is fixed.

Finder Window is always open upon start up of MBP.

Hello:
Just bought a new MBP 2.2Ghz C2D 15.4. running Leopard.
Each time I turn on the laptop. The finder window is open to my home folder.
What could be the cause of this and is there a way to correct it?
Thanks!

Do you mean that finder is open on your dock, and if you click on it, you get the window with your home folder? That's the way mine works too--I just assumed it was supposed to be that way.
Or am I misunderstanding your question?

Add on page always opens when starting Firefox

Why does the add on page open up every time I launch Firefox? It does it only on my desktop computer, not my laptop and they both have the same version and options.

Firefox will not open on my computer the majority of the time. If I shut down and restart it will work sometimes, but not always. This started recently in the last two weeks. Today is June 12th 2011.

CD/DVD drive opens on start and restart

This has been a problem ever since I installed 10.3.9 about a year ago.
Every single time I start up or restart the machine the CD drive pops open.
I'm running a 400 MHz PowerPC G4 (grey tower) and I've installed a LaCie CD/DVD drive. The drive was installed long before the upgrade to Panther and it was not a problem in OS 9 nor in 10.1.x.
Aside from being annoying, it means that I can't start from a CD, which I need to do to run things like Diskwarrior.
400 MHz PowerPC G4 Mac OS X (10.3.9)

Are you using an Apple keyboard and mouse? I just did the firmware update on a 400MHz Sawtooth G4, and the problem you describe started happening to me. I was/am using a non-Apple keyboard and a PS2-USB converter to plug it into the Mac. I just did the 4.2.8 firmware upgrade, and now the drive tray opens on boot/startup. It didn't do that before the firmware upgrade! I hate it when updates/upgrades create more problems than they solve. Anyway, I borrowed a friend's Apple pro keyboard and mouse, and with those plugged in, everything is normal. So if you aren't using an Apple keyboard, you might try plugging one in to see if that fixes the problem.

When I start Safari 5.1 in Lion, it always opens the last page opened. Is there a way to start on the homepage?

When I start Safari 5.1 in Lion, it always opens the last page opened. Is there a way to start on the homepage?

That sounds great, but on my system, that box is not at the bottom of my Pref/General page, but is when I log out and put it to sleep. What is really annoying is that I have to do this every time, instead of unchecking it and it being permanent. Yes, I have Safari 5.1 and Lion. I would like to permanently disable this as I too, think it is absurd and not a great idea when banking, paying bills, etc.

Firefox opens with a window that says "Checking for compatibility for Add-ons" then it always opens 2 tabs... one with my home page and one that says Congratulations, Firefox is up to date. How can I stop it from starting that way?

Firefox opens with a window that says "Checking for compatibility for Add-ons" then it always opens 2 tabs... one with my home page and one that says Congratulations, Firefox is up

Hi konee,
You should look at [https://support.mozilla.com/kb/Firefox+has+just+updated+tab+shows+each+time+you+start+Firefox this article about that specific issue] and the article [http://kb.mozillazine.org/Preferences_not_saved Preferences not saved]. These should give you all the information you need!
If that doesn't work:
# Type about:config in the address bar
# Click ''I'll be careful, I promise'' if prompted
# In the Filter input field type ''startup''
# Double click on startup.homepage_override_url
# Delete the text string and click ''OK''
# Close Firefox and reopen the window to verify that it has worked.
Hopefully this helps!

Bookmark sidebar always open when I start Firefox. How to prevent?

Upon starting Firefox, the bookmarks sidebar is always open. It is a nuisance to constantly need to close it. This has never happened before. It suddenly started a couple weeks ago and now the sidebar is open each morning I open Firefox. I can't find any options for it in the menu. Just the temporary closing. Using Firefox 26.

You can check for problems caused by a corrupted localstore.rdf file.

It always open system preference and firefox everytime i start my mac

it always open system preference and firefox everytime i start my mac.
what should I do to get ride of it?

When you shutdown a window appears to uncheck the loading of programs when the machine starts back up again.
Unfortunately one of Lion's annoyances is you have to keep unchecking this box each time as it rechecks itself.
A hack is to lock a preference file (aka .plist), I haven't tried it.
Unfortunately, it will recheck itself. One permanent fix is as follows:
1. Close all apps you don't want to open at startup.
2. Open your user Library folder. It is normally invisible, so press the Option key while selecting the "Go" menu in the Finder then select "Library" to open it.
3. Use the Get Info dialog "Locked" checkbox to lock this plist:
~/Library/Preferences/ByHost/com.apple.loginwindow.*.plist
where "~" is your home folder and "*" is a sequence of characters (12 in my case). No need to delete the corresponding lockfile.
This plist is where the System stores "reopen windows" info, so the System can't change/delete it if it is locked. Works fine for me and others.
hope it works for you.
Also look for Lion Tweaks, that also may help.
Also take a look at my large post here for backup, restore and other information
