Mar 5, 2012
I have a macbook pro purchased last June. Want to connect an external display and the only option is usb. Apple does not make a minidisplay to usb adaptor and I can not find one on line. Computer will not recognize the display connected directly to the usb. What can I do?

My Mac mini is connected to a Samsung widescreen (1360x768) display using mini port to VGA adapter. When starting, the both sides of the screen is not used, left black. Mac mini thinks the display is a 4:3 display, but does not recognize this as a 16:9 display. What can I do?

I hooked up my macbook pro to a mini display port to a dvi -> hdmi to my tv no problem. However, when I hooked up the mini display -> dell monitor, I get nothing. The screen is black. The weird thing is that my macbook pro recognizes that a second monitor is plugged in... it just won't display anything

I have a mid-late 2008 MacBook connected to a Dell U2211H monitor using a Mini DisplayPort -> VGA connection.
When I use 1920x1080, I only get 60 Hz and the display is a fuzzy (text). Also, there are black bars. Why?
Will my issues be solved using a Mini DisplayPort -> DVI connection? Or should I exchange it for the 2209?

I just got a ps3 and what it boils down to is that I cannot use the ps3 and my macbook on my wireless network at the same time. I have the late 2008 unibody 2.0 macbook. Each plays nice with the network individually but as soon as I try to connect to the internet on both at the same time they crap out and I get the "your computer is not connected to the internet" error message in safari and a similar message on my ps3.
I tried researching it online and all I could find is that the routers DNS server could possibly be issuing the same ip address to both units and this could be causing the problem, seeing as you can't have the same ip address twice on a given local network. I've done all the basics like restarting each machine, disconnecting and reconnecting etc and it doesn't seem to work.

My macbook pro 15's screen is dead and I don't want to buy a new one. I've been using it connected to my tv for a while now and the display has started to feel irritating and unnecessary so I wanna get rid of it completely.

I have a MacBook Pro 13'' (mid 09) and another MacBook pro 15'' (early 09). The problem below applies to both of them.
I often use my 15'' mbp connected to a usb keyboard, mouse, display etc. Basically it is used as a stationary computer that can be easily moved (to work/school etc). This is my main laptop so this is where I noticed the problem first. Sometimes when just using the computer as normal (using itunes, opera, adium etc) the OS X will just suddenly become very sluggish and unresponsive.
However it is not OS X itself, but the GUI! Example: if I move my mouse over the dock, it wont animate. If I try to do any finder related action the GUI response is way of and if I try to do something in the menubar I have to hold left click, if I let go it just closes the menu.
This goes for the application folder as well (I have it as a list). Normally it will just funtion as normal but when this problem occurs I have cant let go of the mouse button when moving through the menus because then the menu closes!

I have a 19-inch Envision EN9410e LCD flat panel monitor. Right now I did a mirror display setup. The native resolution of this monitor is 1280 x 1024. When I went to System Preferences to change it to that resolution my LCD monitor shows the Snow Leopard desktop but it's in the middle of two black bars. I had to revert to 1024 x 768 resolution to not have the black bars show. Is there a way I can change it to the native resolution and not have the black bars on the top and bottom show up on the screen?

When I connect my 13" MBP to an external display to watch a movie etc. the external display seems to be darker than it would appear if I was watching on my MBP. Is there anything I can do to make things brighter (other than turning the brightness up on my TV)?

My Macbook Pro (15 in 2 GHz core i7) absolutely crawls when I plug in the thunderbolt display. I'm running on snow leopard with 4 gigs of memory. Ive made all the neccesary updates. I plug in the screen and close my laptop and the computer gets unbearably slow. Once I open it up it gets way better and when I unplug the display it goes back to 100% speed. Ive called apple and they cant figure it out. Ive taken it to the apple store and they tell me they cant figure it out.

I am going to install a new SSD drive on my MBP mid-2009. After it is installed, can I then start up computer and then insert the DVD Install operating system disk, or do I install the DVD install disk, then shut down computer and swap the HD drive? I know that I will reformat the disk when Installer begins, but I want to know if the computer will recognize the install disk with a new blank HD in place.

The menu that lists the choices for my wifi internet connection includes the internet connection I set up with the SSID that I recognize (call it A) - but it also contains another SSID that I may have set up a long time ago and forgot about (call it B). B's SSID is the same name as the brand of my router; it has no protection listed. It also gets better connectivity than SSID A. How can I find out if B is actually my own connection? How can I add a security password?Â

"This page can't be displayed because your computer is currently offline" - what exactly does that mean? I've gone through and repaired by hard drive, and there didn't seem to be a problem there. I've manually entered in an IP address several times...and I've checked that there are no proxies selected.

WITHOUT closing the lid, because i like using the touchpad. i know that you can turn the brightness all the way down, but sometimes windows from the main screen randomly open on the other display. and it also slows down performance. i want to turn off the 13" screen as if the lid was closed. that way, the mac doesn't even see it.

After months of an incredibly slow internet connection @ home I finally discovered the problem. I have a MacBook Air 1.6 GHz Intel Core 2 Duo. It can connect to any wireless network at home, school, office, etc. However, when at home I connect my Macbook Air to a 23" Apple Cinema Display (ACD) the internet goes from 1500 Kbps to 60 Kbps. Not believing the reason I have tried it several times and there is no other factor. At home I use a 2701HG-T 2Wire router.
Updates:
1) I do not have a network adapter so I can't know if the same would happen with Ethernet.
2) The problem exists whether with my MBA is opened or closed.
3) I do not change the location of my MBA when I connect it to the ACD.

After using my MacBook Pro I close the laptop and it goes to sleep. Later when I return to it and open it, sometimes it can't find the network. The computer is able to see that I have an Apple Network available, but it won't connect.Sometimes when I try to connect, it gives me a timeout. How I fix it is to walk over to the router and unplug it and plug it back in. After I get the green light again, I go to the Apple Network and it works.

I have 2 Macbook Pro's, a 2009 and this brand new one I got today. My external hard drive is a 1 TB clickfree. It has worked for months on my old Mac but when I plug it into my new mac it doesn't even show up in finder or disk utility. I tried the USB ports with another device and they work fine. So it isn't a hard ware issue. The cables are USB 3.0. The external hard drive model number is HD2037N3.I have tried taking everything off (huge pain) and reformatting the drive and still it doesn't recognize it! how I can get my Mac to recognize it?

My macbook is running Mavericks OS X 10.9.4, and I'm having difficulty getting rid of the vertical black columns on my computer screen when it is connected to my classroom projector. I've played with the resolutions, and the best resolution for the VGA display is 1024x768...Unfortunately this creates less than desirable black columns on my computer screen. Another teacher in my school has display settings of "1024x768 stretched," and her macbook does not have the issue mine does. However, I don't think she is running Mavericks 10.9.4. I cannot find this display option on my computer.

I have a 2 month old 13" MBP which I absolutely love. The only hitch is that there is an oddity when connected to my Dell 2008wfp display. It only happens when I wake the MBP from sleep. A number of things happen sometimes. Usuaully, when I wake the MBP from sleep, i get a black screen on both displays and all I can see and control is the cursor. Sometimes the main display will be black, but the MBP display will show the desktop wallpaper, but again, I can only see and control the mouse cursor. It should also be worth mentioning that the keyboard is rendered non-functional as well.
Sometimes, OS X will appear on both displays, with mouse cursor active, keyboard inactive, but I am unable to click anything or interact with anything OS X.
Anyway, I'm at the point where I need to mention this because it happens quite frequently and its getting rather annoying. The only way I can get out of this hang, is to cold reboot the machine. It happens everyday and at least 50% of the time I wake the MBP from sleep. When not connected to the display, I never get this occurrence. Also, this display worked perfectly when I used to own the classic 15" MBP, so its hard for me to pinpoint what exactly is the anomaly that is happening.
Anyone else experiencing this same issue? I am using a mini display port to DVI adapter to the Dell display.

Well my unibody macbook display decided to screw up last night, it was working fine last night no problem. Connected to a external monitor. I fell asleep last night with front row left on, obviously it went to sleep and then I woke up and the screen was black. Now the LED lights are working, my external display is also working. The display settings recognize a screen being present (when I click detect displays and gather windows - 2 windows appear). Ive reset PRAM, SMC, reseated the RAM, control+shift+eject (which just made the screen flicker a little after turning it back on) and Im out of ideas. Its out of warranty and about about 18months old.

I would like to connect my Macbook Pro to my hometheatre via HDMI. Normally no problem with the mini display port and an HDMI adapter, but the port is already used for the 27" cinema display... Is there another adapter available that let`s me connect both, an HDMI device and the cinema display to my Macbook? I only care about the sound - I want to get digital sound to my receiver. (I am not interested in the solution via airport express and then connect via analogue audio cable - I am looking to get a digital sound signal all the way through...) about Macobook Pro: mid 2010, 17", Processor 2.53 GHz Intel Core i5, Graphics NVIDIA GeForce GT 330M 512 MB) Â

I have a Late 2011 MBP, just recently I also go an Xbox and wanted to hook it up to my external display that I have been using for a long time with no issues. I went and bought this: URL....to be able to easily switch between the two inputs. The xbox works fine, however when I view my Macs input the screen flickers a static image very frequently.Â
I know what you're thinking, it's probably an issue with either a cable, or the device. But when I boot into Windows via Bootcamp with the same exact setup, there is no flicker at all. The display is a dell s2440L, the HDMI adapter is a rocket fish.Â
Here are the troubleshooting steps I have tried:Â Resetting PRAM/SMCChanging out HDMI cables on both the Splitter output, and the inputs (I tried 3 different cables on both the inputs, and outputs.)Downgrading OSX to 10.7 (And then went back to 10.9)Lowering the resolution on the monitor (Lower resolutions flicker just as much, if not more.)Resetting the splitter by unplugging the HDMI cord powering it and plugging it back in.and of course, plugging my computer into the splitter input that the Xbox works fine on, as well as taking the xbox one out so the computer is the only input on the splitter.Â
Like I said, the Xbox works fine, and even the computer works fine in Windows, but whenever I boot into OSX my screen flickers with this static. I should add, the display works fine when not connected to the splitter on OSX.
