Macbook does not recognize external monitor

Hi,
I have a Macbook and I tried to connect an external Benq FP93GW using a Mini DisplayPort to DVI Adapter but the external monitor does not detect any signal.
Any suggestions?
Thank you in advance for any help.

You might read this post of someone who couldn't get his external display to be recognized until he reset the MacBook's SMC (System Management Controller).
http://discussions.apple.com/message.jspa?messageID=9351216#9351216
This thread also has some other details on trying to workaround color issues on the external display but it was a reset of the SMC that finally allowed the MacBook to recognize the display. However, Apple cautions that a reset of the SMC should only be done after other options or possibilities have been exhausted. Before you try a reset of the SMC you might want to try a reset of the MacBook's PRAM.
Here is a link to Apple's support article on resetting the SMC:

Windows 8 Bootcamp Does Not Recognize External Monitor

So, my Bootcamp of Windows 8 does not recognize my external monitor when I try to plug it in. I have read that the startup must recognize the monitor during the boot process. However, I have already done this and my external monitor remains in sleep mode. My drivers are all up to date with this bootcamp and I work on programming a lot so I need a solution for this issue because going back and forth between windows of the internet and my code is not ideal for me and wastes too much time. The external monitor works when I run my OS X, just not on Windows 8. If anyone could point me in the direction of how to solve this issue, it would be greatfully appreciated.

They're downloadable. But I'm going to create a system restore point in case something happens.
The below discussion had a similar issue but with Windows 7

Macbook does not recognize external USB drive - except when booting with CD

Hi all,
I recently swapped my Macbook's internal HD (Toshiba 100gb 5400 rpm) into an external USB enclosure (Eagle Consus). The computer does not recognize the external HD, even when using two USB cables for extra power. No luck with safe mode or resetting PRAM. Disk utility just hangs with spinning wheel if I start it. Switching the USB ports does not help.
I thought it might be a power problem until I noted the following:
1)The external drive works fine if I boot the Macbook from the Mac OS install CD... with this I can run disk utility and scan the drive with no problem
2)It works fine on an old Mac Mini with only ONE of the USB connectors plugged in
3)The enclosure worked fine on the Macbook when I had the new drive in it (320 GB 7200 RPM) while copying the files over
Any thoughts?
Many thanks,
--T

It is actually using a power supply, yet it will not actually power on unless it is connected to a computer's USB port. At least this is how it works on my old desktop running Windows 2000. When you disconnect the drive from Windows, or put the machine in hibernate mode, the device actually shuts down. It powers back up once the machine wakes up from hibernate mode.
It's a somewhat older device which predates the Macbook Pro, but it claims to support older Mac, such as the G3, G4, G5, iMac, iBook. OSX 10.0.4. So perhaps it's just too old?
It's a Buffalo HD-HB250U2 (250 GB).
So you're in Japan too?

IMac does not recognize external monitor using Mini Display Port to HDMI

Hello,
I have been trying to get an external monitor (HDTV) set up for use with my iMac using a Mini Display Port to HDMI cable I just got. However, when I connect it to my iMac's mini display port, the imac's screen goes black for about a second, then returns, but it does not detect the external display. The other display is just showing a "no signal" message on the screen.
I have restarted, reset PRAM, connected and disconnected the cable several times, tried changing the resolution on the imac, plugged in/out the other display, and clicked the "detect displays" button using the option key in display preferences, but nothing has worked.
I am using an early 2009 iMac running Mavericks.
I've been using the AirParrot app, but it's horrible for video and a little slow.
Can anyone please help sort the issue here? I feel like ive exhausted everything that I know to do.
Thanks.

I am having the same issue. Hope Apple can fix this soon!!!

MacBook Pro does not sense external monitor (Panasonic HDTV in my case) via thunderbolt-HDMI connection...Is update 10.8.3 helping anyone?

My MacBook Pro (newest model in 2013 so far) does not sense external monitor (Panasonic HDTV in my case) via thunderbolt-HDMI connection...Is update 10.8.3 helping anyone else who has this issue? I returned my multiple HDMI adapters after figuring out it had to be an Apple issue n not the adapters so I can't check it myself now.
Thanks!

I have late 2012 MBP 13" and connect to my Panasonic Plasma correctly.
But using the same cable, can't connect to an LG 47LM6200, the MBP detects the TV, the screen blinks blue, but the TV shows "no sinal detected" message.

Macintosh: Flash Player does not recognize external webcam

Hi,
the Adobe Flashplayer does not recognize an external webcam on my iMac. When I open Settings and try to choose a camera, it offers:
DV Video
IIDC FirWire Video
USB Video Class Video
The last entry activates the built-in iSight camera, but not the Logitech Camera which is connected via USB. If I choose one of the other options, the picture freezes, but it does not activate the external Logitech cam.
The Computer recognizes the Logitech Cam alright, it works fine with other apps (Skype, iChat). Does anyone have an idea what can be the problem?
Webcam: Logitech Vision Pro USB für Mac, nagelneu
Computer: Intel Mac, OSX Tiger 10.4.?
Browser: Mozilla Firefox
Thanks for any help!

I've been trying to work through similar problems, as have many other Mac users from what it looks like. Here's a quote from a post I found in Apple's forum:
My Logictech 9000 doesn't show up in the Flash video source dropdown for me either. Selecting USB camera just selects the iSight.
However, I did find a workaround: it seems to choose the first available usb webcam, which is typically the built-in iSight. If you have a mac mini with no built-in iSight, it uses the external camera by default. For my MacBook, I found the trick was to make the iSight busy by opening Photo Booth first, then opening the flash chat page. That causes the flash player to find and use the external USB webcam.
Note: your webcam probably has to support the new standard USB Video plug-and-play protocol for this to work, and perhaps only on Leopard.
Here's the link to the page where I found this post:
http://discussions.apple.com/thread.jspa?threadID=1374761
Hopefully this works for you if you haven't already found a solution - I see you posted back in April! I'm sorry that no one attempted to answer your question before now, including the Adobe people who staff these forums!

New Macbook does not recognize Time Capsule backup from old macbook

I just purchased a late 2013 13" macbook pro. I have a mid 2009 macbook pro running Mavericks. The new macbook will not recognize the time capsule backup from my old macbook. I am trying to migrate all data over, but the new mac does not ever acknowledge the external drive that contains the backup. I've tried two different external drives with the same result each time. Both computers are running Mavericks.

Do you see the drive in Disk Utility?
If yes, run Repair Permissions then restart the drive.
1. Open Disk Utility in your Applications/Utility folder.
2. Click on the First Aid tab and select Repair Permissions
3. Click on the icon for your boot volume.
4. Click the repair permissions button.
In System Preferences > Time Machine can you select the old Time Machine with Select Disk?

New MacBook does not recognize bluetooth mouse

I just migrated to a new MacBook, running (OS10.6.8) and it will not recognize my Logitech Bluetooth laser mouse. The mouse works just fine with my old MacBook. I downloaded control center, but that also does not recognize the mouse. Any help would be appreciated.

"browse device" showed the mouse, but said it was not connected. I started the setup assistant, but it did not seem to see the mouse. But I noticed a tiny button on the bottom of the mouse labelled "connect" and pushing that while running setup assistant seems to have done the trick. Now I hope it "sticks".
Thanks to IAmMe123 for pointing me down the right path.

MacBook does not recognize Treo 650 Bluetooth DUN!

Hey gang-
We got our new MacBook today. For some reason, it does not recognize the Bluetooth Dialup Networking (DUN) capability of my Palm Treo 650. I have no problem creating the trusted pair, and the MacBook and Treo discover each other no problem. But when I finish setting up the trusted pair, the Bluetooth Setup Assistant reports "There were no supported services found on your device"
Now here's why I'm worried- In the exact same setup, my 1-year old iBook G4 recognizes and offers the choice of Bluetooth Dialup Networking from my Treo! Something is definitely different in Bluetooth support in the MacBook.
Any got a MacBook to recognize Treo 650 DUN?
Thanks!
Dave

I am having the same problem with both a brand-new Macbook and intel iMac. After going through setup identically to several other Macs around, I only get "There were no supported services found on your device." Bluetooth syncing works fine, but neither of the Intel machines will find the DUN. Powerbook G4 12in and iBook G4 12in both work fine with identical setup procedures. There is definitely something buggy here.

Mac mini does not recognize external drive

I have an 80GB external drive full of music files. I disconnected my computer to move to a new house and, with everything re-connected, the mini does not recognize the external drive. I wonder whether it is because the internal drive is nearly full. I have tried restarting the computer, disconnecting and re-connecting the USB cable to the external drive, serching for it with the disk utility, un-pluggin the external drive power cable and re-connecting it, but I'm out of ideas. What might have happened?

My iMac does not recognize external hard drive

My iMac does not recognize my external hard drive. Disk utility recognizes it and a test of the hard drive does not review any error. I use the hard drive as a back up for the time machine. This problem comes and goes. It comes when I turn off and turn on the computer, with the hard drive attached.
Please help.
Insightful

can be this reasons
01 , you have problem with connection ? check the port if you can find any problems physically .
02. if not try to change the cable and with connection ,
03. may be its good idea to check the hard drive with another mac ?(if you have )
Did you note any diference of sound from Hard Drive ? listen to it that carefully to note some unusual sound comes when the hard drive works.
check this link this might usefull: http://www.youtube.com/watch?v=JjgOSxKy-FQ

MBP Does Not Recognize External USB Devices

MBP does not "see" external USB devices (such as Garmin Nuvi GPS) or any thumb drive. No external USB devices show up in Finder nor does Disk Utility see them. No cable issues. Have tried restarting several times, but to no avail. This MBP used to recognize these USB devices, but no longer do so.
I have seen this question posed several times in forum, but no suitable answer. Don't know if it is H/W or S/W problem.

Hi Terry Temple
Is there at least any power going to the USB ports? ( as in if for example you plug in a USB light, will it switch on? )
If there is power in the USB ports it might be a software problem.
Try resetting the SMC see link: http://support.apple.com/kb/HT1411
also try re-set the PRAM see link: http://support.apple.com/kb/HT1379
However if you do not have any power at all it probably is a hardware problem.
Is it still under warranty?
Regards,
Andrew

MacBook Pro 2011 does not detect external monitor

I have a MacBook Pro 13'' early 2011 runing Lion 1.7.2.
I have an HP v185ws external monitor connected via an Apple Thunderbolt to VGA connector.
Since last month's Thunderbolt firmware update, my external monitor is no longer detected.
Does anybody has a solution to this problem?
Thanks.

I have a problem connecting external display (Dell U2311H) to my 13" MacBook Pro (Early 2011).
I use Tecklink Mini DasplayPort to HDMI adapter (http://www.techlink.uk.com/products/wires_cables/wiresmedia/wiresmedia_media/wir esmedia_mini_displayport_plug_to_hdmi_plug), but since U2311H doesn't have HDMI input, I also use Manhattan DisplayPort to HDMI Adapter (http://www.manhattan-products.com/en-US/products/8101-displayport-adapter).
And nothing.
The display is not detected, no picture or even external monitor presence at all.
I even reset PRAM, and installed 10.8.2 Supplementary update.
I also plugged and unplugged all I could, with no luck.
As I can see on Apple discussion, it is a common problem with 2011 MacBook Pro's.
It seems like the problem is in Thundebolt port, it somehow does not work properly.

My macbook does not recognize my external hard drive

I have a brand new external drive which I have already formatted in FAT32 and previously used in my MBP with no issues at all. From a couple of days ago though it simply ceased to appear on my Desktop, Finder or Disk Utility. It is, however, recognized in the System Profiler or System Configuration when I click on the USB port tab. No physical damaged has been applied to the HD, and the light turns on normally, making a perfectly normal noise. As I said, it used to run just fine on my MBP, and even on other Mac computers and PC's.
I took it to a store with Apple technical support, they plugged it into one of the store's Macbooks and, surprise surprise, it magically appeared and worked perfectly. They even tried it on a Windows PC and ran just fine. Came back home, turned my computer on, connected it and the problem persists....
Any ideas?... Can you help me?
My specs are:
15'' Macbook Pro 5,1 with an Intel Core 2 Duo 2,4 GHz processor and 8GB of RAM
Mac OS X 10.6.8 fully updated
Western Digital Hard Drive - WE Elements SE Portable WDBPCK0010BBK-01

Did you get a solution for this issue ? I have the same HD which works fine on two other Mac Book pros (Snow leopard and mountain Lion) but does not work on a brand new mac book pro with Mavericks
