OS X :: Can't Get Anything To Show Up On Screen - Just Background
Dec 27, 2009
I own a new 13" MB and a Samsung 40" a550 LCD TV. i bought a Mini-port-to-DVI cable and a DVI-to-HDMI. I hooked the HDMI into the 2nd monitor HDMI-slot on the back of the TV and the Mini-port into the MB. I can only get the TV to display the "standard" Mac desktop background -the one thats the picture of outer-space (purple & blues). but i cant get anything to show up on the screen other that just that desktop background. nothing else shows up.

So my problem with my Macbook Pro's pixels is many of them look blurry and are multiple colors almost like a rainbow. They also only show up on white backgrounds, not black. Some of them are in clusters and others are spread out. One of the clusters is very annoying and looks like a big blurry dot on my screen. I am hoping to take it in to the apple store and see what they can do about it because it seems like it is getting worse. I am assuming these are all dead pixels but I am not certain.

I have a problem with my desktop background i tried clicking "change desktop background" but it wouldn't show the window where i can change the background, i tried the right click to a specific image and it doesn't say about using it as a desktop background. doesn't require removing nor deleting certain files i'm very wary about eleting certain files i own to where if i did delete or remove a file or program the computer would be messed up and i would have to find that Mac OS X 10.5 disk to restart it all over again and rebuild everything.

Display flatters for up to one second while doing the regular boot.Means it gets blue with Apple logo bright - like a negative of original screen.Was not observed with Mavericks first releases .1, .2.iMac Late 2013, 27 inch, NVIDIA GeForce GT 755M 1024 MB.Again possibly a problem with SMC and it's reset as first solution candidate,or rather graphics?

I cant figure out how to change the background color of it in candybar. I'm sick of the standard grey mac color.When I'm in candybar I go to the dock section-->view-->dock-->preview background..the options under preview background are greyed out. Also when I am in the dock section-->view-->background-->change color. I try changing the color but it doesn't change. Am I doing something wrong..or what?

I have a Macbook Pro and I have been recently changing around my backgrounds including my login background. However, when I changed my background via command in the terminal by switching the defaultdesktop.jpg with another picture in the CoreServices folder, My picture does not show up on the login screen instead it is just a plain blue screen. Is there anyway to restore the original login background settings?because I actually found a program "loginox" that easily changes the login picture however, it will not open because it says I have changed the original background photo.

I'm not happy with the backdrop that appears on my display when my MBA starts up, before I log in to my user account. So I'm not referring to the wallpaper that you'd see on the desktop if all your applications were minimised or closed, but the background when you first switch the notebook on (visible when the theme tune is played, and the apple symbol shown). The MBA I purchased in September had a lovely background that was a subtle cross hatch of dark and medium grey. The newer model, purchased this June (after I destroyed the first one through water damage) has a boring, solid light grey background instead. I haven't been able to work out how to alter this in system preferences.

MacBook Air, OS X Mavericks (10.9.4), Purchased June 2014

I was watching YouTube on my Mac book Air. I paused it and closed the laptop. When I opened it and tried to turn it on, it shows a blank screen. But when I press esc, I can barely see a very very very faint login page with the box asking for my password. When I type my password, it logs in and I can play the YouTube and hear everything and all. But my screen is just black. My keyboard lights doesn't light up either. I've tried everything.

Whenever I start up my macbook it stayed on grey background with an apple logo and spinning thing. I press and hold the shift key once and it went to safe mode and did my diagnostic and found out that some file got corrupted so I thought maybe I'll just do another start up and everything will go back to normal. Then I restart it again but this time it wont past that grey back ground w/ apple logo w/ spinning thing again. I tried to do the safe mode again and it won't let me anymore. I went to apple site and i found a bunch of keyboard shortcuts, non of those help me. Any here have any idea what might happen to my MacBook. I'm in Kazahstan for work related trip and they don't use Mac here so there is no where I can buy another snowleaopard cd.

I have an iMac 21inch, Late 2009. I found after it was runing really slow that my hard drive was failing. It told me there were SMART errors on the drive. The computer is out of warranty and I'm in the middle of no where so i have no Mac store to take it to. I bought a new drive, same model, and installed it into the computer. It turns on fine, but after the Apple logo and spinning coge wheel the screen flashes, shows the blue back ground like its going to load the desktop and then goes black.
I've tried connecting an external monitor to it and shows up like an extended display. I've tried connecting it to another Mac, a Mini, and the Mini can boot off the iMacs hard drive just fine. If it Target Disk mode the Mini and boot the iMac I get the same flash of blue desktop then it goes black.
This is where it gets weird though, I'm sure your thinking, ok the screen is going bad... BUT, I boot off an Ubuntu CD, or the AHT disk and it loads fine and has no turning black. Its only when booting into the Mac OS or the installation disk.
One last note is that when its at the black screen and I'm sure its loaded the desktop, if I hold the power button down for about 3-4 seconds, till I hear a click. I then press the button again right away and the screen flashes on showing me the desktop and everything, for about 2 seconds...

My tibook .867Ghz was working fine this morning, but now when I restarted it this afternoon, the colors are all off (lots of green and rapidly vibrating pixels in background). The computer works, I can run programs and so forth. There are no changes to the displays settings, still 1280x854 and colors "millions". When I switch to thousand or 256 colors there is no significant change.

I have my 24" iMac connected to a 22" LG monitor via an Apple mini DVI to VGA. The best resolution the monitor will run at is 1680x1050 which I guess is the native resolution.
My problem is that there is a black line at the bottom of the screen, and I can drag windows of the top of the screen by about the same amount as is missing of the bottom. What can I do to get that bit of screen to show up in the right place?

When I switch between applications such as Safari, iTunes and iPhoto, the screen doesn't show - only the grey tool bar at the top. I think have to click on the appropriate application in the dock for the screen to reveal itself.
What setting do I need to change to be able to see the screen immediately when I switch to the application?
btw, I generally use the cmd/Tab command to switch between applications.

The title pretty much says it. If I uncheck the "show Visualizer in full screen" box it works, but if I have it checked it won't run the visualizer. Even if I am already running the visualizer then right click and choose show in full screen it just brings me back to the music page. This is realy been baffling me.
This particular system is running Windows 7 64 bit. My Win 7 Laptop running 32bit it works fine. Not sure if this has anything to do with it but I figured it was worth a mention.

i have had my macbook go to sleep an not fully wake up, the keyboard, cd drive wake an the screen would just turn the LED on, it brights up but does not show anything.i do NOT think its hardware, i believe the os is just not turining on the screen or speakers. it has done this 2 times an had to hardboot. before i hardboot it, i let it sit for a few minutes to see if it would wake up fully , an tried to close the lid again. also is there a short cut to restart or put it back to sleep so i dont have to hard boot. i dont expect to have this happen again , but if it does a key would be nice

Today, while turning on my iMac, a strange gray progress bar appeared in the 'Apple' start screen. I assume I felt some fear. Then, the login screen shows in red: 'Safe Boot'. Later, the menu bar appeared to be brighter than ever. Thanks to google, I found that safe boot is a mode which you can access by holding shift during startup. Probably I pressed shift accidentally, even though I do not remember. The question is: now, that I restarted my mac and it's back to the normal, will this 'Safe Boot' bring me any consequences? How to proceed?
