OS X :: Dock Disappearing Suddenly / Activity Monitor Flashes And Then Disappears
Dec 24, 2007
Very suddenly my dock has disappeared, (and occasionally reappears), and is now completely non-useable. Why..?
I have created other accounts on my computer previously and the dock on those is fine...I have looked in Activity monitor and it flashes on and then disappears in there. I tried using terminal to 'killall Dock', but this did nothing...Am using Leopard on Alu iMac.

I leave the Acitvity Monitor running all the time with my CPU Usage as the dock icon. I like to see the cores working away. On my Quad MacPro at work I have four blue bars, on my old iMac C2D, MacBook etc. I have two bars. On my new i7 QC iMac I am only getting one bar. Any body have any thoughts on why this is? Has Apple changed the way the icon shows cores? Here is a link to a photo of my current dock on my i7. Current Dock Icon on i7 Quad Core
I have a 21.5" iMac bought in November 2009. I am having a strange happening with it. I have just been using Mail, clicked on the red button at the top left to quit, but the mail window just kept disappearing all but about 3mm off the screen to the top and top left and not quitting. I have also had this happen when using Safari, occasionally if I click on a link on the page to another open another page Safari disappears off the top and top left except for about 3mm.
I have no idea what happened, but a lot of small stuff on my mac either disappeared or changed. I took my macbook off the charger after a nights charging, and I noticed: all my icons on my desktop were no longer there, my widgets were all gone, and all my programs gave me a setup up screen when I tried to use them. I'm not too upset because everything on the hard drive is still there, but still I'd like if anyone has a clue to as what the heck I did to cause this?
I'm not sure why but whenever I go onto the internet, my wallpaper disappears and it turns blue. If I want to restore it I have to click on a different wallpaper in system preferences then click back to the one I want. Any ideas?
Anyone come across this? I 've been having it a lot recently on my imac, not my pbook though, and I can't seem to find how to fix it... very strange behaviour, as soon as you start writing the cursor vanishes...make for some very hard writing I tell you...
Well, that's ms, they might even have it as an option somewhere that I cannot find...
Every time I wake up my Mac Pro, the monitor flashes 2-3 times before it is fully on. Quite annoying. Any idea what it might be? I have the latest Mac Pro 2.66 Quad (got a referub about a month ago) and LaCie 526 (same as NEC 2690). Basic video card, DVI connection.
I have been using the latest macbook pro 13.3" since April 2010. Over the last week the monitor suddenly goes completely white and the external monitor goes black. The laptop becomes unresponsive although the programmes opened continue running (e.g a skype voice call would continue without interruption although the monitor is all white).
The only solution at the moment is to press the turn off button for a few seconds then switch the laptop on again. It will then work normally until for no apparent reason this happens again.
When Safari is active, the menubar and the dock disappears. I have chosen not to show/hide dock in system preferences, and whenever any other program than Safari is active, the dock and menubar stays put. My OS is 10.7 - P.S. I have not maximized the Safari-window.
What could cause this, and how do I get the dock and menubar to stay even when Safari is active?
The dock on my Mac only appears when I click on it. I'm pretty sure I just accidentally pressed a keyboard shortcut, but I don't know how to reverse it.
I already tried Command+Option+D, but that's not the problem (it's not that my mouse has to hover over where the dock should be - I physically have to click in that space. As soon as I click on another application, the dock disappears again).
I have been trying to figure out why my MBA seems to be so odd?
I am running 10.6.2 OSX and every time I try to move the icons around in the dock they either move place by themselves or delete themselves?
This is especially true with browser icons. For example I could have safari open and try to move the icon in the dock from the far right towards the left ..... It will do this and stay there for approx. 5 seconds and then return back to the far right.?
If I close the safari program the icon disappears from the dock. If I then try to drag the safari program into the dock from the applications folder, it will sit there for 5 seconds again and then just delete itself off the dock. This also happens to Skype, Firefox etc.....
I have tried everything from terminal / killall Dock ..... to deleting files from /Users/~/Library/Preferences/com.apple.dock.plist etc with nothing working ??
// ps I do have a mobileme account with syncing function but have dock syncing turned off etc .... I have also tried re-booting multiple times after trying different routes and nothing has worked.
After trying nearly everything I can think of (even checking repairing in disk utility) I seem to have drawn a blank.
So I have enclosed a video of my desktop showing the problem of the disappearing icons. The weirdest part is its selective so some icons could stay when being dragged their while other disappear in a matter of seconds?
When I open up mail, the dock and the header bar both disappear and won't return even if I hover the mouse in the area. Have tried changing preferences for dock and have reset the dock - still not working.
I just purchased a MBP (prev gen) about a week ago, and I've been noticing something weird in the dock. This usually happens a few minutes after I boot the computer from being completely off, but what seems like an Application quickly shows in my dock and then disappears. It happens in a split second and there's not enough time to see what it is. It just opens and closes. I haven't installed much on this MBP, just Office, Firefox, Visualhub, Mactracker and perian and flip4mac. I have all these Applications installed on my iMac and I have never seen this happen before.
My Safari and iTunes icons are just spaces on my dock. There is no icon for either of them. If I click where there would be an icon, the programs launch. If I hover over the spaces, it shows the name of iTunes and Safari like it does for every other program. When they are open it shows the little light under the blank space like it normally would.
This morning my wireless mouse needed battery replacement. After that, the cursor disappears as I move it away from the dock area. If I move over buttons and am lucky, the proper action will take place but I cannot see the cursor. Sort of like playing Battleship game. Blindly move the mouse and hope I hit something. Although this is new this morning, I've had the same problem in the past but it went away. It seems worse or much more annoying this morning.My wired mouse displays the same problem. I had to borrow my wife's laptop to send this problem. The only program open is Safari.
I installed Leopard from an OS disk I purchased to upgrade from Tiger. I just went to launch Activity Monitor and it is not there? I checked Applications and Utilities. From what I read it seems that Leopard should have activity monitor.
So maybe what I am looking for is in the activity monitor, but I just can't find it. I always see people on here posting screen shots of their CPU usage. If they have a quad core machine then there are four columns with blue in it showing the usage. Where can I find this in OS X, or is this a 3rd party program?
Im running SL (updated of course) on my MacBook Pro 4,1. Im fairly new to Macs and to be honest I didnt even know about Activity Monitor till very recently. So I figured I would check out whats going on with my system and fire it up. Activity Monitor does not respond. It starts to open but then sits at this screen with a beach ball...
After a while I usually just Force Quit. Ive ran Onyx recently as well as Disk Repair and everything seems ok.
I have an Apple Cinema HD 23" ( HDMI port) and a 19" off brand (Thunderbolt port) hooked up to the Mini. It is most noticable using Photoshop but happens using other software or just using Safari.
Moving cursor from one monitor to another it will disappear. does not happen all the time. clicking on desktop will make it come back. very inconsistant. I have applied all system and firmware updates. any solutions or are we still waiting for Apple to fix this.
Info: Mac mini, Mac OS X (10.7.3), i5 chip with 8GB ram
My doc disappears every few minutes than reappears suddenly. I have no idea why this is happening. When the doc disappears from the bottom of my desktop I cannot downsize anything until it reappears. Very frustrating! I tried to find something in system preferences but couldn�t. Has anyone else out there had this happen? I�m running 10.2.4.
A while back I installed an application that allowed me to stream media from my Mac to my PS3, called Gridcast. It didn't work well, so I got rid of it. Since then I have had two processes constantly running, "gridcastd" & "GridCastAlerts." When i select and quit the processes nothing happens, they just continues to run.
According to the screenshot, both Users (green) and System (red) uses 0,19% CPU each. Which means that idle (black) should be around 99%, which it clearly isn't. If I check each process individually, none is using more than 1% of CPU. The screenshot is taken after a reboot and I don't use and third-party background services like VMWare. It's Mac Pro 2.66 Quad (2009).
