IMac HD icon became "client node" then disappeared

I noticed a few days ago that the iMac HD icon renamed itself “client node” on my desktop then the icon disappeared completely after restarting. I was able to put an iMac HD alias on my desktop so I can access my HD files, but now Time Machine is not backing anything up. It goes through the backup process every hour as set, but there is nothing being backed up on Time Machine since the iMac HD disappeared from my desktop.
What is this “client node” thing (what happened???) and where is my HD icon?
So far I’ve run Cocktail, repaired permissions, relaunched the Finder, restarted my iMac, shut my iMac down overnight and booted it up in the morning. Still missing the HD icon (and HD files).
When I click on the HD icon in the sidebar, the HD alias shows a grayed-out HD icon in the list of HDs (my iDisk, iMac HD alias, Network, & Time Machine). I can access the HD files through the HD alias, but where did the actual HD icon go, and how do I get it back?

I think what may have happened is that your HD somehow acquired a "hidden" flag, making it invisible to Finder. I have seen a "client node" icon appear on the Desktop transiently when I have deliberately made a disk volume invisible using a Terminal command. The "client node" icon disappeared if I then relaunched the Finder. I'm not sure what it represents - it may just be a transient Finder "ghost" of an object which has just become "hidden".
To restore visibility to your startup disk, I would try the following:
Launch the Terminal - it is /Applications/Utilities. Next copy-paste the following line into the Terminal window, followed by typing <Return> :
sudo chflags nohidden /
Enter your admin password at the prompt (it will not echo on the screen) and again type <Return>.
Do you now see the HD icon?

Menu Bar Icons Appear...then Disappear, then Reappear

I can't find this problem anywhere else on the internet being addressed. I have a MacBook Pro 2Ghz Intel Core Duo. Ever since I did a clean install of Leopard I have this weird problem. In the upper right corner where the Finder, Battery, Volume, Wireless, Date/Time and Stacks Icons are located, they will appear, then disappear, then reappear constantly. Ive tried restarting, Ive even gone into the System Preference to choose the Time/Date option. When I click display time in Menu Bar it will let me select it, then when the icons disappear that option goes away in sync. Very strange, has anyone else had this problem and have a cure for it?

I'm having the exact same problem and I know what's causing it but I don't have a solution to fix it. It is happening for me due to my Firewire CD/DVD drive. It's just a regular Sony drive that never had any problems with 10.4. Now though when DVD is mounted it starts up the menu bar issues. When I eject the DVD the menu bar goes back to acting normal.
I did a google search and found another thread on the macfixit forums. One guy found a solution to fix his problem with it and that was to trash these two preference files in your home/Library. One was com.apple.finder.plist and I can't remember the other one. I tried it but it doesn't work for me since it seems to be my firewire DVD drive that's causing the issues.
Do you have an external Firewire device connected? If so try disconnecting it and see if that fixes your problem. I sure hope apple fixes this issue soon.

What do I do when trying to download Lion from the app store and the icon says "waiting" and then disappears.

I am trying to update a new iMac from Snow Leopard to Lion. When I click on install in the app store, the LIon icon jumps down into the dock and nothing happens. The message above the icon is "waiting." Eventually, the icon disappears. How can I install Lion?

Start with http://www.apple.com/support/mac/app-store/

My default photo viewer and default jar opener both result in the picture of the icon getting big and then disappearing without opening a picture/program. Please Help.

Please help. I have tried redownloading java and attempted to open the jar file with Terminal. Nothing is working.

First, uninstall "SuperTV" (whatever that is) according to the developer's instructions. It isn't working and it's filling the log with noise.
If you have more than one user account, these instructions must be carried out as an administrator.
Launch the Console application.
Step 1
Make sure the title of the Console window is All Messages. If it isn't, select All Messages from the SYSTEM LOG QUERIES menu on the left.
Enter "BOOT_TIME" (without the quotes) in the search box. Note the timestamps of those log messages, which refer to the times when the system was booted. Now clear the search box and scroll back in the log to the last boot time when you had the problem. Post the messages logged before the boot, while the system was unresponsive or was failing to shut down. Please include the BOOT_TIME message at the end of the log extract.
Post the log text, please, not a screenshot. If there are runs of repeated messages, post only one example of each. Don’t post many repetitions of the same message. When posting a log extract, be selective. In most cases, a few dozen lines are more than enough.
PLEASE DO NOT INDISCRIMINATELY DUMP THOUSANDS OF LINES FROM THE LOG INTO A MESSAGE. If you do that, I will not respond.
Important: Some private information, such as your name, may appear in the log. Edit it out by search-and-replace in a text editor before posting.
Step 2
Still in Console, look under System Diagnostic Reports for crash or panic logs, and post the most recent one, if any. In the interest of privacy, I suggest you edit out the “Anonymous UUID,” a long string of letters, numbers, and dashes in the header of the report, if present (it may not be.) Please don’t post shutdownStall, spin, or hang logs — they're very long and not helpful.

How do I stop a notify icon appearing multiple times... then disappear when mouse hovers over them

Hi,
[Re-posted
from Outlook Dev Forum]
I have an Outlook addin which makes use of a System.Windows.Forms.NotifyIcon to display update message without requiring the user to click Okay to dismiss them...etc.
I declare and create it in the addin class (so not in start up or any other event) as:
Public WithEvents notifyIcon As New System.Windows.Forms.NotifyIcon
Then throughout in my code if I need to display a message I use notifyIcon.ShowBalloonTip. This works great, and I run it off the main thread as well as a syncing background worker thread. The problem is that when I go down and expand the
system tray, there are often many clones of the icon I use, which then disappear when I hover my mouse over them.
I understand this isn't an uncommon problem, and it happens also with new email icons in the system tray. However, is there any way I can prevent this from happening, or best practices I need to abide by?
In the Shutdown event I use:
If notifyIcon IsNot Nothing Then
notifyIcon.Visible = False
notifyIcon.Dispose()
End If
Any help would be much appreciated, since I can't seem to find any definitive info elsewhere online.
Thanks!
Tom
Note: I don't actually use a windows form with the notifyIcon, I just declare it as above... not sure if that affects anything?

Would this be the same as using the Application_Quit event for the Outlook addin? Since I've
seen that in Outlook 2010 onwards it doesn't call the Shutdown event now anymore, so you need to use the Quit event of the application to do any tidy up. Maybe that is why the icons are remaining.
Thanks,
Tom
Hello,
Wyck has shared a nice example with a form event, and for outlook 2010, we could deal with that notifyIcon inside application quit event.
Based on the document below you shared, it seems that you have found the reason, if that issue still exists, please feel free to let us know.

When I go to Preview to view a photo it shows up for less than a second then disappears and just leaves a gray box where the photo should be. iMac (Retina 5K, 27-inch, Late 2014). I need Preview for work.

After the OS X Yosemite 10.10.3 update When I go to use Preview to view a photo it shows up for less than a second then disappears and just leaves a gray box where the photo should be. iMac (Retina 5K, 27-inch, Late 2014). I need Preview for work.

1. This procedure is a diagnostic test. It changes nothing, for better or worse, and therefore will not, in itself, solve the problem. But with the aid of the test results, the solution may take a few minutes, instead of hours or days.
The test works on OS X 10.7 ("Lion") and later. I don't recommend running it on older versions of OS X. It will do no harm, but it won't do much good either.
Don't be put off by the complexity of these instructions. The process is much less complicated than the description. You do harder tasks with the computer all the time.
2. If you don't already have a current backup, back up all data before doing anything else. The backup is necessary on general principle, not because of anything in the test procedure. Backup is always a must, and when you're having any kind of trouble with the computer, you may be at higher than usual risk of losing data, whether you follow these instructions or not.
There are ways to back up a computer that isn't fully functional. Ask if you need guidance.
3. Below are instructions to run a UNIX shell script, a type of program. As I wrote above, it changes nothing. It doesn't send or receive any data on the network. All it does is to generate a human-readable report on the state of the computer. That report goes nowhere unless you choose to share it. If you prefer, you can act on it yourself without disclosing the contents to me or anyone else.
You should be wondering whether you can believe me, and whether it's safe to run a program at the behest of a stranger. In general, no, it's not safe and I don't encourage it.
In this case, however, there are a couple of ways for you to decide whether the program is safe without having to trust me. First, you can read it. Unlike an application that you download and click to run, it's transparent, so anyone with the necessary skill can verify what it does.
You may not be able to understand the script yourself. But variations of it have been posted on this website thousands of times over a period of years. The site is hosted by Apple, which does not allow it to be used to distribute harmful software. Any one of the millions of registered users could have read the script and raised the alarm if it was harmful. Then I would not be here now and you would not be reading this message. See, for example, this discussion.
Nevertheless, if you can't satisfy yourself that these instructions are safe, don't follow them. Ask for other options.
4. Here's a general summary of what you need to do, if you choose to proceed:
☞ Copy a particular line of text to the Clipboard.
☞ Paste into the window of another application.
☞ Wait for the test to run. It usually takes a few minutes.
☞ Paste the results, which will have been copied automatically, back into a reply on this page.
These are not specific instructions; just an overview. The details are in parts 7 and 8 of this comment. The sequence is: copy, paste, wait, paste again. You don't need to copy a second time.
5. Try to test under conditions that reproduce the problem, as far as possible. For example, if the computer is sometimes, but not always, slow, run the test during a slowdown.
You may have started up in "safe" mode. If the system is now in safe mode and works well enough in normal mode to run the test, restart as usual. If you can only test in safe mode, do that.
6. If you have more than one user, and the one affected by the problem is not an administrator, then please run the test twice: once while logged in as the affected user, and once as an administrator. The results may be different. The user that is created automatically on a new computer when you start it for the first time is an administrator. If you can't log in as an administrator, test as the affected user. Most personal Macs have only one user, and in that case this section doesn’t apply. Don't log in as root.
7. Load this linked web page (on the website "Pastebin.") The title of the page is "Diagnostic Test." Below the title is a text box headed by three small icons. The one on the right represents a clipboard. Click that icon to select the text, then copy it to the Clipboard on your computer by pressing the key combination command-C.
If the text doesn't highlight when you click the icon, select it by triple-clicking anywhere inside the box. Don't select the whole page, just the text in the box.
8. Launch the built-in Terminal application in any of the following ways:
☞ Enter the first few letters of its name into a Spotlight search. Select it in the results (it should be at the top.)
☞ In the Finder, select Go ▹ Utilities from the menu bar, or press the key combination shift-command-U. The application is in the folder that opens.
☞ Open LaunchPad and start typing the name.
Click anywhere in the Terminal window to activate it. Paste from the Clipboard into the window by pressing command-V, then press return. The text you pasted should vanish immediately.
9. If you see an error message in the Terminal window such as "Syntax error" or "Event not found," enter
exec bash
and press return. Then paste the script again.
10. If you're logged in as an administrator, you'll be prompted for your login password. Nothing will be displayed when you type it. You will not see the usual dots in place of typed characters. Make sure caps lock is off. Type carefully and then press return. You may get a one-time warning to be careful. If you make three failed attempts to enter the password, the test will run anyway, but it will produce less information. If you don't know the password, or if you prefer not to enter it, just press return three times at the password prompt. Again, the script will still run.
If you're not logged in as an administrator, you won't be prompted for a password. The test will still run. It just won't do anything that requires administrator privileges.
11. The test may take a few minutes to run, depending on how many files you have and the speed of the computer. A computer that's abnormally slow may take longer to run the test. While it's running, a series of lines will appear in the Terminal window like this:
[Process started]
        Part 1 of 8 done at … sec
        Part 8 of 8 done at … sec
        The test results are on the Clipboard.
        Please close this window.
[Process completed]
The intervals between parts won't be exactly equal, but they give a rough indication of progress. The total number of parts may be different from what's shown here.
Wait for the final message "Process completed" to appear. If you don't see it within about ten minutes, the test probably won't complete in a reasonable time. In that case, press the key combination control-C or command-period to stop it and go to the next step. You'll have incomplete results, but still something.
12. When the test is complete, or if you stopped it because it was taking too long, quit Terminal. The results will have been copied to the Clipboard automatically. They are not shown in the Terminal window. Please don't copy anything from there. All you have to do is start a reply to this comment and then paste by pressing command-V again.
At the top of the results, there will be a line that begins with the words "Start time." If you don't see that, but instead see a mass of gibberish, you didn't wait for the "Process completed" message to appear in the Terminal window. Please wait for it and try again.
If any private information, such as your name or email address, appears in the results, anonymize it before posting. Usually that won't be necessary.
13. When you post the results, you might see an error message on the web page: "You have included content in your post that is not permitted," or "You are not authorized to post." That's a bug in the forum software. Please post the test results on Pastebin, then post a link here to the page you created.
14. This is a public forum, and others may give you advice based on the results of the test. They speak for themselves, not for me. The test itself is harmless, but whatever else you're told to do may not be. For others who choose to run it, I don't recommend that you post the test results on this website unless I asked you to.

ITunes 11.3 icon bounces in my dock then disappears.

Have new iMac with iPhoto sharing turned on. When the shared library is clicked the library disappears or starts to load then disappears? What is wrong?

Have new iMac with iPhoto sharing turned on. When the shared library is clicked the library disappears or starts to load then disappears? What is wrong?

Try this: launch iPhoto with the Option key held down and create a new, test library. Import some photos and check to see if the same problem persists. If it doesn't then your current library is damaged and needs repair.
Therefore make a temporary, backup copy (select the library and type Command+D) and apply the two fixes below in order as needed:
Fix #1
Launch iPhoto with the Command+Option keys held down and rebuild the library.
Since only one option can be run at a time start with Option #1, followed by #3 and then #4 as needed.
Fix #2
Using iPhoto Library Manager to Rebuild Your iPhoto Library
Download iPhoto Library Manager and launch.
Click on the Add Library button, navigate to your Home/Pictures folder and select your iPhoto Library folder.
Now that the library is listed in the left hand pane of iPLM, click on your library and go to the File ➙ Rebuild Library menu option
In the next window name the new library and select the location you want it to be placed.
Click on the Create button.
Note: This creates a new library based on the LIbraryData.xml file in the library and will recover Events, Albums, keywords, titles and comments but not books, calendars or slideshows. The original library will be left untouched for further attempts at fixing the problem or in case the rebuilt library is not satisfactory.
If you experience the same problem with the test library then try this basic fix a try: make a temporary, backup copy (if you don't already have a backup copy) of the library and try the following:
1 - delete the iPhoto preference file, com.apple.iPhoto.plist, that resides in your
User/Home()/Library/ Preferences folder.
2 - delete iPhoto's cache file, Cache.db, that is located in your
User/Home()/Library/Caches/com.apple.iPhoto folder.
Click to view full size
3 - launch iPhoto and try again.
NOTE: If you're moved your library from its default location in your Home/Pictures folder you will have to point iPhoto to its new location when you next open iPhoto by holding down the Option key when launching iPhoto. You'll also have to reset the iPhoto's various preferences.
NOTE 2: In Lion and Mountain Lion the Library folder is now invisible. To make it permanently visible enter the following in the Terminal application window: chflags nohidden ~/Library and hit the Enter button - 10.7: Un-hide the User Library folder.
If that fails a reinstall of iPhoto is indicated. To do so you'll have to delete the current application and all files with "iPhoto" in the file name with either a .PKG or .BOM extension that reside in the HD/Library/Receipts folder and from the /var/db/receipts/ folder,
Click to view full size
Then install iPhoto from the source it came on originally.

Running cs4 w/mavericks. won't print from PS. Printer icon appears then disappears -

This started recently. I think I was in the middle of setting up a custom size for my epson 2880 when something happened. Now when I try to use the photoshop controls printing command, I'll hit print, it will start to respond, the printer icon appears then disappears and then nothing happens. I can print from other apps, I use quad tone rip for b&w and am now printing color using color sync, I can also print from LightRoom, but no luck through PS.

Has most recent drivers.
Yes, it will print from a PDF – it will print from preview, Acrobat, Word, OpenOffice - Anything other than InDesign it seems!
Tried deleting and re-installing printer. No change, unfortunately.

On ebay front page summary the 'ended' list title appears briefly, then disappears - only happens of Firefox on the imac.

When I log onto ebay and go to the front page with a summary of my account, under the Watch List there are headings for all the items. As the page loads the heading for 'ended' appears in the bar, then disappears.
I've tried deleting the tab; removing cookies, but it keeps happening. This is only on my Apple imac, using Firefox - on my Windows using Firefox it's fine.

mixalis88,
I appreciate the suggestion, but that did NOT fix the problem. I, however, HAVE fixed the problem...I now use Google Chrome as my browser.
It may not be perfect, but it correctly displays the websites I visit most, and I dont get that Goddamn annoying re-direct page in Google like I do in FF.
I use to LOVE FF...but until they work out the bugs, I'm done with it.

Click on it, choose Get Info from the File menu, and check the format.
If it's formatted as NTFS, reformat it as MS-DOS, exFAT, or Mac OS Extended (Journaled) as desired, or install software such as Paragon NTFS on the computer.
If it's formatted as FAT32 or exFAT, use the Disk Utility's Repair Disk command on it; this may also happen for a flash drive which is about to fail.
If it's formatted as Mac OS Extended, click Authenticate and provide your administrator password, or change the permissions on that specific folder in its Get Info window.

Dude or hot-spur,
Not fishy at all!!!! You really think I would have taken any more of my time to post a bogus rant? We'll no, it is unfortunately all true. I want to hear from anyone who is experiencing such problems not anyone else that wants to put there two cents in. I really don't need anymore hate or negativity. Just people's experiences because I feel like I am the only one having so many problems. Thank you
Yes, I have had some unfortunate bad luck to have so many problems at the same time, but some of them are just things you cannot do on the new OS.
Thank you again
