My iMac does not see the new Toshiba external drive in Finder or Disk Utility. How can I get it to see the drive?

My iMac does not see the new Toshiba external drive in Finder or Disk Utility. How can I get it to see the drive?

From the menu bar, select
 ▹ System Preferences ▹ Energy Saver ▹ Power Adapter
and uncheck the box labeled Put the hard disk(s) to sleep when possible, if it's checked.
If the drive has more than one interface (USB, FireWire, Thunderbolt, eSATA), try one of the other interfaces.
Check that the data cable is securely inserted at both ends.
Try a different cable.
If you're connecting the drive through a hub, connect it directly to a built-in port on the Mac.
If you're connecting it directly, try a different port.
Disconnect all other devices on the bus, or as many as possible.
Test the drive with another Mac. Test another drive with this Mac.
If the drive is bus-powered, but has an AC adapter, connect the adapter.
Start up in Recovery mode and launch Disk Utility. Is the drive recognized?
Start up in Safe Mode and test.
Reset the NVRAM.
Reset the System Management Controller.
If the drive doesn't work under any of the above conditions, and if another drive does work with the same Mac, then the drive is malfunctioning.

IMac does not see my external HD...but my MacBook Air does

I have a Toshiba 1TB HD that I partitioned into iMac and PC. I run my backup on it with no problems. Then I got a Time Capsule and set it up. Now my iMac does not see my HD any more. But my Mac Book Air picks it up. You can see the 2 partitions on the MBA. I also cant see it in my Disk Utilities and "Mount" is not clickable. I tried to use different USB ports as well as different USB cables.

What to do if your computer won't recognize a FireWire or USB device...
If the issue persists, try these steps:
   1. Shut down the computer.
   2. Disconnect all devices and all other cables, except the keyboard and mouse cable(s).
   3. Disconnect the computer from the power outlet and wait for 3 to 5 minutes.
   4. Plug the computer back in and turn it on.
   5. Reconnect the device(s) (one at a time if there is more than one) and test. Test with each port if you have more than one.

After upgrading to Mavericks my iMac does not see Sony camcorder in iMovie anymore. It still works on MacBook, so nothing wrong with camera or connections.

After upgrading to Mavericks my iMac does not see my Sony camcorder anymore. I tried the new iMovie as well as the old version 9.0.9, which is still in Applications. I checked the camcorder and connections in iMovie on my MacBook (not upgraded) and that still functions properly, so the problem does not seem to be in iMovie, old or new, or in camcorder and connection.
Anybody with the same problem or a solution?
Thanks mbkom

IMac does not 'see' Sony DCR PC5E when connected

It depends on what Mac you have and what version of iMovie. You may need to use Firewire.

MBA mid-2012 does not see external display on wakeup

My mid-2012 MBA does not see external displays on wakeup. VERY annoying
I have a BenQ 24" HD display connected by HDMI and it is not seen by the Air on wakeup. I have to open the laptop, pull the mini-DV plug out 3 or 4 times before the display is recognised - some of the time. Most of the time requires a reboot with multiple cable/plug inserts.
What an absolute POS this mid-2012 MBA is! Apple finally fixed the garbage colours on external displays in 10.8.4 but the issue of recognisisng external displays remains. Its a crock. Totally regret buyiing this POS.
Have reset PRAM, SMS, cleared prefs etc etc ad nauseum. No solution with any of them. After almost a year of this garbage, the laptop is close to being thrown out as e-waste.

Trying to see DVD drive through DVD sharing. iMac does not see MacBook. DVD sharing is ON.

I have an iMac with a non-working DVD drive and I'm trying to install Snow Leopard from my MacBook's DVD drive. I have turned DVD Sharing ON but the iMac does not see the DVD drive in Finder's Shared Devices. I have tried FireWire, LAN through TimeCapsule and WiFi. Am I missing a step?
The iMac and MacBook are both late 2007 purchases and have 10.5.8.
Thanks for any help.

Two commands you need to type in terminal on the computer that has the dead drive.
Disk sharing like the macbook air does is one of those things that's included in all OS X's on all computers, but that is not enabled. (I think it's cause apple doesn't want to have to support it on more devices that they absolutely have to)
So here's how you enable it.
In your Utilities Folder, open Terminal
copy and paste each line:
sudo -s
*type your password*
defaults write com.apple.NetworkBrowser EnableODiskBrowsing -bool true defaults write
com.apple.NetworkBrowser ODSSupported -bool true
shutdown -r now
Okee dokee... That last command will restart your computer, then you're off to the races!

Imac does not detect external vga display

Please help with connecting external vga display to an imac 21.5'', late 2012, OS X 10.8.5 via Mini DisplayPort to VGA adapter.
I have connected an external monitor (Fujitsu Siemens) to the thunderbolt port of the imac using a Mini DisplayPort to VGA adapter. The imac does not detect the external monitor. I have followed all instructions and suggestions I could find at Apple Support Communities without success.
The monitor is in perfectly good working order as it has no problem connecting and performing flawlessly with a dell windows laptop. The imac, connected via the Mini DisplayPort to VGA adapter to the D-Sub connector of a Samsung smart TV, also worked perfectly.
To add insult to injury, occasionally, when restarting the iMac with the external vga display connected and powered on, the iMac screen starts intermittently turning blue for a brief second or so and resuming back to normal. The frequency of 'blueing' is once in 2-3 seconds. This particular rather disturbing problem, luckily ceases when the external display is switched off.
Any advice and help with resolving the above connection problems will be gratefully appreciated.
Thank you

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

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

Capture mode does not see external camera

When I use the capture in iMovie, it only allows you to choose the built in iSight camera, and the external web cam is long listed as a choice. The external works fine in other programs (like skype).
Is iMovie intentionally crippled to only work with iSight in capture mode? Or am I doing something wrong?
THanks
bob

Thanks for your help...
It is a Logitech Quickcam Pro 9000 using drivers from mac.
It does show up in USB section under apple system profiler.
It is connected through a powered hub (I have tried it directly connected with no difference).
It is recognized fine in other programs, such as Skype (you can change from isight to external web cam).
I downloaded and installed iGlasses 2, but that did not solve the problem. Curiously, if memory serves me correctly, photobooth only works with isight internal, but after iGlasses 2 install, it works (only) with external (when external is available).
Any other ideas on why iMovie does not see the external web cam?

System preferences -Sound does not see external USB speakers

The computer internal speakers are working OK but the problems come when I try to use external USB speakers. The previous volume problem of the imnternal speakers resolved itself.
I have now purchased a new USB set of speakers (BOSE Companion 20) but now they will only work through the "headphone" slot at the rear of my Imac and then only thru one speaker.(right)
I have reset the PRAM - anyway I followed all the instructions and it was not solved.
In "Sounds" in system preferences the Imac cannot see the USB speakers - it only recognises the internal speakers for output.
I think until "sounds" recognises the USB Speakers I will not get both speakers working.
I insert the USB speaker wiring pin in the Headphones slot at the back of the Imac and as mentioned sound only comes thru the right USB speaker -nothing works when I put the pin in the speakers slot alongside the Headphones slot.
Any help apprecaited

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.

Cannot Wi-Fi Sync iPad; Appears to see iMac but iMac does not see the iPad

Like many, I have upgraded my iPad (1st Gen) to iOS 5 and for the most part, it's been an easy transistion to learn the new features. However, I've not been able to overcome a Wi-Fi Sync issue.
The iPad does recognize that it can Wi-Fi Sync with my iMac.
When it was connected via cable, I had already selected the "Sync with this [iOS device] over Wi-Fi" Option in iTunes then clicked "Apply."
Under Settings > General > iTunes Sync on my iPad, the "Sync Now" button is grey when I connect to an alternate Wi-Fi network in our house, but when I am on the same Wi-Fi network as my computer, through an Apple Airport Extreme Basestation, the "Sync Now" button becomes actively black as it if recognizes my iMac, but it does not show up under iTunes to sync.
I connected the iPad to an alternate computer which is linked to iPhone running iOS 5 on the alternate Wi-Fi Network I spoke of earlier and through which we succesfully Wi-Fi Synced, but when my iPad was linked to this same computer (connected first by cable to enable "Sync with this [iOS device] over Wi-Fi" Option in iTunes first, it still would not show my iPad. And this time, not even my iPad would see the computer when on the same network, yet I could also see the iPhone mentioned which was upstairs.
I have tried following the steps in this Help Page (http://support.apple.com/kb/TS4062) but without any change. The only thing I haven't followed to the letter is restarting my router. I did tell my Airport Basestation to restart via the Airport Utility.
Has anyone else yet experienced this issue and been able to resolve it? Please share any insight.

When one device can't see another via Bonjour, it suggests a problem with how the network or the devices are handling "multicast" packets. Handling multicasts is tricky on Wi-Fi. Is there any way you can temporarily plug the iMac into the LAN port of the base station via an Ethernet cable, and try the sync that way? If that works, then it's a clear indication of multicast problems on your network.
Apple is usually very good about making sure multicasts work reliably on AirPort base stations and all Macs and iOS client devices. It would be interesting to know which generation of AirPort Extreme you have, what firmware version you're running on it, exactly which wireless security mode you're using (for instance, WPA2 "mixed mode", where both WPA2-style AES-CCMP and original WPA-style TKIP encryption are available, is trickier for multicasts because multicasts have to use a different cipher and key. "WEP TSN" is also tricky for similar reasons). Oh, and what you have your "multicast rate" set to on your base station.

Maverick does not see External Harddrive

I had a Seagate external usb3 harddrive connected. I was working on a video file when suddenly I got a message in the upper right hand corner saying that the external harddrive was incorrectly disconnected or dismounted. OK. So, I unplug and then plug the ext. HD back into the usb3 port. To make the story short, the hd light comes on, I can hear the disk spinning. But it does not appear in the Finder or desktop. The only sign on the Mac is by going to the "About This Mac" and to the System Report which lists hardware and software. Clicking on the USB line, it shows the external HD plugged into one of the usb 3 ports. The disk info indicates its ID and other data and how much energy it is consuming (it appears it is only using 96 mA from an available 500 mA). So, it appears that the Mac sees it and can read it and has power enough to run it.
I then removed the first ext. HD and inserted another Seagate external usb3 harddrive - the Mac doesn't see it either except in the System report. The external HDs do not show up in the Disk Utility app. The only conclusion is that the harddrives are probably OK but the Mac won't mount them anymore. Most people with unmountable ext. HDs usually see them in the disk utility (greyed out).
Any ideas.

Update - I have three Seagate FreeAgent GoFlex external harddrives. The two that I have connected to my Macbook Pro no longer can be read. I took the two and connected to another MacBook Pro but it would not read the drivers either. I took my third drive which I have not connected to my Macbook Pro for several weeks and connected to the other Macbook Pro and it reads it fine.
I downloaded drivers from Seagate but it didn't help. I started my computer in safe mode, HD didn't work. I have another drive containing a duplicate of my internal HD (using Superduper) and booted with the backup drive. It would not open the two drives. I'm taking the HD to a friend who has a G5 using an early Mac OS, 6.0. These two drives contain my video files and I need to retrieve the files.
Conclusion: The Maverick on my computer has corrupted the first two Seagate drives.

Bridge CS4 Does Not See External Drive

Very suddenly, Bridge is not seeing the external USB connected driver I use to store recent photos. I read a similar message here and the writer was told to add the drive to favorites. That appeared to work for him, but I could not do that since the folder doesn't appear under Computer in the favorites section either. The drive appears in Windows Explorer. I am using Vista 32. Any suggestions?
Fran

Did you power up or connect the external drive after Bridge had been started? I've observed that Bridge only includes drives that were attached and active when Bridge was launched; it does not add a drive to its folders list if that drive is started after Bridge is active. With your external drive on (and appearing in explorer) try exiting and relauching Bridge.
