New 27 iMac won't mount my 3tb WD My Book.

New 27 iMac (10.7.3) won't mount 3tb WD My Book. It worked fine for about a month and then suddenly said it wasn't ejected properly (it wasn't ejected at all). Now my iMac won't recognize the drive. It doesn't come up in disk utilities, it's invisible.
I think the issue may have started when I restarted my iMac. First the power of the external drive wouldn't come on and now that I resolved that I can't get it to mount.
Help!

Disconnect all your peripherals, reset the PRAM
and then reconnect everything.

Imac won't mount lacie drive

I had a new internal hard drive installed on my iMac. The data from the old drive was backed up to a Lacie P'9231 external hard drive (brand new). Now, the iMac won't recognize the Lacie drive, so I can't reinstall my data and settings.
When I start up the iMac, it goes through the whole multi-lingual welcome and then asks whether you want to set up a new computer, restore the computer from another part of the internal drive, or use Time Machine to restore it. I checked Time Machine because I thought that the iMac would see the Lacie as a Time Machine device. It doesn't. As far as I can see, the obvious stuff--connections, power, etcs, are OK.
I'm wondering if I shouldn't just let the internal hard drive set itself up and THEN import the backup from the Lacie drive, rather than attempt to import through Time Machine.
Any ideas?

One of those options should be to restore from another disk/volume/partition. Use that.

My iMac won't mount or even read my NTFS external hard drive

I have a new model iMac running 10.9.4
I have a 4TB usb 3.0 external Seagate hard drive formatted in NTFS.
I cannot get the iMac to recognize it.
I've tried:
- mounting via disk utility: "the disk could not be mounted. try running first aid on the disk and then retry mounting" I haven't tried first aid because I don't want to erase or change anything on the hard drive. It also said I could try verifying the disc but haven't done that for same reasons. It works perfectly fine on my 2009 iMac.
- Finder preferences - external discs is checked
- I installed an app called NTFS-3G which was recommended along with MacFUSE 2.0 but that didn't seem to do anything
The only place I can see my hard drive is in disk utility, but it is grayed out.
Any help would be much appreciated.

You must remove the "NTFS-3g" software.
Any third-party software that doesn't install by drag-and-drop into the Applications folder, and uninstall by drag-and-drop to the Trash, is a system modification.
Whenever you remove system modifications, they must be removed completely, and the only way to do that is to use the uninstallation tool, if any, provided by the developers, or to follow their instructions. If the software has been incompletely removed, you may have to re-download or even reinstall it in order to finish the job.
I never install system modifications myself, and except as stated in this comment, I don't know how to uninstall them. You'll have to do your own research to find that information.
Here are some general guidelines to get you started. Suppose you want to remove something called “BrickMyMac” (a hypothetical example.) First, consult the product's Help menu, if there is one, for instructions. Finding none there, look on the developer's website, say www.brickmymac.com. (That may not be the actual name of the site; if necessary, search the Web for the product name.) If you don’t find anything on the website or in your search, contact the developer. While you're waiting for a response, download BrickMyMac.dmg and open it. There may be an application in there such as “Uninstall BrickMyMac.” If not, open “BrickMyMac.pkg” and look for an Uninstall button. The uninstaller might also be accessed by clicking the Customize button, if there is one.
Back up all data before making any changes.
You will generally have to restart the computer in order to complete an uninstallation. Until you do that, there may be no effect, or unpredictable effects.
If you can’t remove software in any other way, you’ll have to erase and install OS X. Never install any third-party software unless you're sure you know how to uninstall it; otherwise you may create problems that are very hard to solve.
Trying to remove complex system modifications by hunting for files by name often will not work and may make the problem worse. The same goes for "utilities" such as "AppCleaner" and the like that purport to remove software.

New 27" iMac won't display above 1280 x 720

I just got my new 27" iMac but the max display size is 1280 x 720.
I went for the higher-end NVIDIA GeForce GTX 780M. On first startup the screen is full of static and then is drops into the 1280 x 720. I tried zapping the PRAM but the same static problem happens.
I'm trying to get in touch with support but the support page is giving me error messages.

I restarted my system this morning, and the correct display rersolution is currently working. No update was installed this morning. I had the system up and running overnight setting up iTunes Match. Can't explain it, but we are fully up and running now. I am going to do some more testing with it and send an email to my support rep with this screen shot. WOOT. Display finally looks as amazing as I was promised. Also did a Graphics Benchmark last night, and got results:
FPS:
100.8
Score:
2539
Min FPS:
45.3
Max FPS:
198.2
Which blew my 2 windows desktop machines with NVIDIA Desktop Graphics cards out of the water. Now I can play with photos!

New Hard Drive Won't Mount

I have an iMac running Leopard 10.5.1 and recently bought a 500GB drive to go into an external housing. All went well but when I turned it on...nothing.
I looked at system profiler and it sees my disk and tells me the size etc and that it's connected to the firewire bus.
In disk utility it shows, but in the disk tree, the actual partition is greyed out although the disk itself is there.
I cant mount it from there, I get the following error 'Disk cannot be mounted, try running first aid'. So I run first aid and then get the following message: 'filesystem verify or repair failed'
So I take it out of that housing (a FW 400 Firecor II rack unit caddy system) and try it in a LaCie housing (Quadra aluminium style) BINGO, Mounted first time!
So I put it back in the Firecor unit...nothing! So I tried putting the original LaCie drive that was originally in the housing into the Firecor system..Nothing!
I have another 3 caddy drives that all work fine with the Firecor so I know it's not that and I've tried every configuration, every jumper position, other leads etc etc but I'm stumped. Why does it work in one external housing and not another? Why does the system see it but refuse to mount it?
Any ideas?

No please enlighten me!
Don't forget though that I have others that work perfectly well in the same enclosure and have done for a number of years.
Having done some research it appears that the FW chipset on my Firecor system may not be fully supported by Leopard. It may work, it may not, which is what now appears to be happening.
To make sure, I powered it up on my old POwerbook with 10.4.9 and it worked no problem with both new drives.
I'd still love to know your thoughts...

Brand new 20" iMac won't recognize Ethernet cable - can't get online

I just got my iMac and cannot get the ethernet cable to recgonize. I know it works b/c I'm using it this very moment to type this on my Powerbook. When I plug it into the PB, I get the yellow,then the green once it connects. However, when I plug it into the iMac, I get nothing. I thought maybe I needed to configure Built-In Ethernet, but it won't let me select configure or connect. The assistant won't recognize it either. I posted in the Tiger forum mistakenly, but thought this forum would be more appropriate. This is what I posted (for more detail):
I just unboxed my new iMac and can't get on the internet (I'm on my powerbook). The problem is this; in Network, it says "The cable for Built-In Ethernet is not plugged in." Only, it is. Can't be the cable b/c that's the cable I'm connected with right now. So, I go through "assist me" and when I click on "Assistant" it takes me to the Intro page where I'm supposed to give a Location Name. I do this, calling it "home." The ver next screen, after clicking "continue" takes me to "How do you connect to the internet?" The problem here is that, of the 5 options, only one is selectable. Airport is the only one that can be selected?? "I use a telephone modem to dial my ISP" as well as "DSL Modem/Cable/Lan" are all greyed out..they cannot be selected. I use an ethernet cable. Why is this not able to be selected? It's very frustrating. I've turned off Airport and Bluetooth, yet I still cannot check any of these. I need to check "I use a cable modem to dial my ISP" but I can't b/c it won't allow me. Can anyone help me here? I can't use my brand new iMac and it's kind of a bummer. I thought these things were plug and play? Thank

Well I tried that and nothing. I'm completely stumped. I have no idea why this is happening. And it's weird b/c, everytime I'm jumping back on here, I'm just unhooking the ethernet cable from the iMac and plugging it into my PB. And, nearly immediately, i'm up and running, connected with the PB. How can it work on the PB and not on the iMac? And why would those options be grayed out on the iMac? It's like it just refuses to let me check them and/or configure. That is very weird.

New 27 iMac won't run Chrome Beta (fresh download) - I used Migration Asst.

I just setup my shiny new 27 inch i7 and used Migration Assistant to copy my stuff from an older dual G5 running Leopard. It took nearly 12 hours to copy the 300+GB of data.
Mostly things like iPhoto, Lightroom, Mail, etc. work GREAT.
However, one of the first orders of business was to download the Google Chrome beta which I've been running on my MBP and MacPro.
When I try to open the Chrome app it immediately quits (tried a restart of the iMac). The detail report doesn't shed any light on what happened to me (maybe others would be able to determine the cause from the report).
Any ideas ?
I was wondering if by copying stuff from a Leopard system (and non-Intel) that I now have some backwards compatible setting ON that is preventing Chrome from loading.
I've never used Migration Assistant before, always hand copying what I needed on a fresh install. Maybe I should reinstall Snow Leopard over my current User folders.
Thanks,
Ed

In the end a manual transfer of pictures, music, data, etc. was far faster than using Migration Assistant and worked fine. Just replaced Music, Pictures, etc. with the folder from the old computer and all upgrades were performed and everything was in place.
What really made the manual migration palatable is that I have MobileMe. All of those data files (address book, mail preferences, bookmarks, etc etc) moved automatically via MobileMe sync. Without MobileMe, it would have been much harder I suppose.
More difficult was the hassle of reinstalling Adobe Creative Suite, Office, etc. But in the end a fresh install of everything has made my new iMac i7 a screaming fast machine.
Absolutely love it !
Thanks for all the advice.

New intel iMac won't run PE3

My new iMac w/ OS 10.5 will not open my PE3. It shuts down before it is fully open!
Can anyone shed a little light on this problem?

Hi Barbara,
Thanks for taking the time to respond. I never installed the Snow Leopard 10.6 that came with the iMac. I've been waiting till I read a bit more about it! PE3 is the only Adobe product on this computer. I downloaded a trial version of the new PE8 and I was pleased with it. It seems a good idea to up grade now and avoid any future problems with incompatibility.
Thanks again,
Hank

New MacBook Pro, Won't mount ANY media in superdrive

I just bought a new MacBook Pro on Wednesday (6.20). I have spent a whole day transferring my info over, and today put in a CD to rip and found that the CD wouldn't mount.
I tired blank media, DVD's, CD's, everything and nothing will mount. It will be sucked in the drive, think for about 6 seconds and spit it out. Restarts haven't worked, I tried to run the Hardware Test, but I can't keep the disc in, so no hardware test. I once put the disc in and shut down quickly, then restarted holding down "d", yet it just spit the OS X dvd right back out when it started up.
I can't take this back to the Apple store till monday. Are there any ways to look at this, or will I just be sending my brand new computer to Apple Care 5 days after I bought it?
MacBook Pro 2.4gHz Mac OS X (10.4.10)

Yes, Please Let me know how it goes. I just left for business with the new MBP and realized the problem so I can't make it to AS till monday. I did call though and of course they said it would go to the Genius Bar.
I asked for the manager and let him know the problem, and kindly told him that I was going to leave the AS on monday with a working MBP. He said, if the drive was dead, he would just swap it out for a new one.
I am not sure how I am going to switch my apple care (since I already registered it)
Hope this helps, and I hope you get you problem solved without loosing the machine to apple care 4 days after the purchase.

Brand new 27" iMac won't turn on anymore.

I bought this computer new on Friday last week. I only got it back from a data transfer yesterday.
Everything was fine until my screen grayed out and said I have to shut down the computer. I shut it down and now it won'tturn back on. I can here the hard drive and fan spin but there is nothing happening on the monitor.
Any ideas?

If the plug is flush inside the back of the machine, and the power outlet you have it connected to works for a lamp, you have a lemon. Bring it back for an exchange.

HT5287 new 27" iMac won't read DVD from older iMac

Have enabled on iMac with teh Optical Drive
Option to enable doesn't exist on new iMac

thanks for your responses and sorry for not asking my question clearly
I know there's no optical drive. I am trying to install Mac 2011 onto my new iMac from my old iMac which has the optical drive.
However the old iMac doesn't show up under Remote in Finder, even though I have enabled CD / DVD sharing
Thanks again

New 13" MBP won't mount or recognize external drives via FW 800

Hi all,
I have a brand new 13" MBP. I have two external 750GB Lacie drives that were formatted for MacOS on my previous 13" MacBook. I mounted these drives via USB on the older laptop.
Neither of these drives will mount on my new laptop via the FW 800 ports. I've tested two cables on both drives and nothing works. Also, neither of the drives appear via disk utility when using FW 800. The drives do however appear when using USB.
Is my FW 800 port faulty? Could it be something else? Thanks!

Hi,
I'm having a similar problem to you - my external drive is not recognised by my MacBook Pro when using FW800 but it is when using USB2.
Did you have any luck getting your firewire to work properly?

IMAC won't boot with USB card reader attached

My quite new 24" iMAC won't boot if I have a USB card reader attached:
I get to the white screen with the apple logo, but it gets stuck there and the little spinning gear below the apple logo never appears (I've waited several minutes). (In all my test cases, there is no card in the card reader.)
I've tried two different card readers with the same results ("iDOTconnect" brand and a brand new Apacer unit, both are USB2.0 multi-format card readers).
The 1st one I tried via a USB hub, the second one I tried via a new hub and also directly connected to the mac (both of those hubs work fine).
Anyone have any ideas?
Regards,
Strathglass

Hello strathglass
The same thing can also happen with other connected devices such as external HD's and iPods, the Startup Manager is lost and searching for a boot volume.
1. You may be able to fix it by going to: *System Preference / Startup Disk* and select the *Mac OS X 10.5.5 on Macintosh HD* then *Click the lock to prevent further changes.*
2. Leave those devices that cause boot issues disconnected until the iMac is up and running!
3. Only sleep the iMac, and be sure to disconnect those devices be for shutting down or updates that require a restart!
As a habit, I have always ejected and disconnected all mounted USB devices (flash driver, iPods, cameras, card reader, etc.) from my hub be for sleeping, restarting or shutting down...

Printing problems with HP laserJet 1320 and new Intel iMac

My new Intel iMac won't print to my HP 1320 from Eudora or from web browsers. The applications "quit unexpectedly". From Safari, nothing happens.
I can print PDF documents and Office documents with no problems. The Intel is connected to a router via Airport. The printer is connected to the router via Ethernet. My old G4 iMac prints fine (connected to router via Ethernet) as does my G4 laptop (connected via Airport).

A post from another threat that might help.
From Payson
Solution!!!
Just spent 90 minutes with some nice folks in level 1 and level 2 support.
Problem seems to be that I used migration utility to import the soul of my old machine into the new machine. When you do that, you bring along the old print system (PPC vs Intel).
I had upgraded to 10.4.5 after the migration and assumed that it would correct any problem like that, but it had not.
After a great deal of trial and error, the solution was to go to move disk/library/printers to the desktop and restart the system
Then use the the install disk 1 that came with the iMac and use the OPTIONAL INSTALLS package to reinstall the printer drivers.
Worked like a champ.
Suspect similar problem might happen for any of you with I/O drivers.

LaCie drives won't mount in daisy-chain setup on new 21" iMac

Hi,
My 2 LaCie externals (Quadra v3 and Quadra v2.1) are not being recognised as a daisy-chain setup with my new 21" iMac.
I have the Quadra v3 connected to the iMac with USB 3.0 cable. It mounts only every 1 in 10 attempts. When successfully mounted, I daisy chain the Quadra v2.1 into the v3 via a FW800 cable and it is not mounting at all.
- Both drives are being powered independently using original power supplies.
- This exact same setup works flawlessly on my Macbook Pro.
- I have updated all firmware using LacieFirmwareUpdater.
- I have tried different cables and using firewire ports.
- I can get the Quadra v2.1 to mount independently using a USB 2.0 cable directly into the iMac. However I wish to daisy chain with Firewire to the v3 and this is not working.
If anyone has had this issue and knows a solution I'd love to hear it!
Regards,
rowbo

You cannot daisy-chain disk drives across different connection types/protocols. In other words, you cannot daisy-chain drives using both USB and FW in the same daisy-chain. This is explained in the Lacie d2 user manuals.
It is, actually, quite surprising that you have been able to do this with your MBP. It should not work at all. You are lucky in this particular case, but I would urge caution assuming that this connection will continue to work, or even work reliably. imho you are lucky you haven't fried your drives doing this, or fried the USB port in your MBP.
Anyway, no multi-connection drive is built to support cross-connection daisy chaining. You can do USB-USB or FW-FW, but not USB-FW.
