How do I connect my intel based imac to a LG LCD tv?

I have a 2007 20 inch Intel core 2 duo iMac and an LG 46" LCD tv. I bought an HDMI cable and a Mini DVI to HDMI adapter but cannot get them to work together. Nothing happens when I click on detect displays in the system preferences.
Do I possibly have the wrong version on Mini DVI, for instance DVI-D instead of DVI-I?

A mini-DVI to HDMI adapter is the correct adapter. for a 2007 20" imac. DVI-I is a combination of DVI-D and DVI-A so a I should work as well as a D.
Set the TV to the input you connected the HDMI cable to.
On your computer, in the Displays system preferences, if there is no Arrangement tab there is something physically wrong with your connection. Try clicking detect displays (you say you alread did that) just to see if the computer can now sense the presence of the connection. Check your cables and connections.
If the Arrangement tab shows two screens then set your computer's Displays preferences for the proper resolution and refresh rate for the TV. You may have to click Gather Windows to get the TV's Displays preferences on to you main screen so you can make those changes. I also recommend turning off mirrored displays if it is enabled.
Note, if you get this working you will need to pass your audio separately (assuming you want audio on the TV) since DVI does not pass audio.

How can I format my intell based imac without the original Tiger discs? I have a user account on it that I dont want. I have upgraded to Snow Leopard but I want to to star affresh. Thank you.

How can I format my intell based imac without the original Tiger discs? I have a user account on it that I dont want. I have upgraded to Snow Leopard but I want to to start affresh. Thank you. I have tried loading the Snow Leopard disc whilst holding down th C key but it goes straight into install mode. I am new to Macs and I have inherited this machine.

Hello, many options...
1. Insert the Mac OS X Install disc, then restart the computer while holding the C key.
   2. When your computer finishes starting up from the disc, choose Disk Utility from the Installer menu. (In Mac OS X 10.4 or later, you must select your language first.)
      *Important: Do not click Continue in the first screen of the Installer. If you do, you must restart from the disc again to access Disk Utility.*
   3. Click the Erase tab.
   4. Click the disclosure triangle to the left of the hard drive icon to display the names of your hard disk volumes and partitions.
   5. Select your Mac OS X volume.
   6. Highlight the drive, select Partition Tab, then Format type... MacOS Extended Journalled, select the Security Options button, choose Zero Out Data, Erase... after completion do a new install.
Or...
Open System Preferences>Accounts, unlock the lock, click on the little plus icon, make a new admin account, log out & into the new account.
In the same pref pane highlight your old account, click the little minus icon, then use Disk Utility to Secure Erase Free Space.

Only 10 seconds of Internet connectivity on Intel based iMac

My iMac of 2007 is having trouble connecting to the Internet.
The setup is pretty straight forward. The iMac is connected through ethernet to a motorola cable modem. The provider is Ziggo. I live in The Netherlands.
Two PC's, a desktop and a laptop work fine and keep working when plugging in the ethernet cable.
Plug the ethernet cable in the iMac and everything works fine too -- Only for 10 seconds! Then internet connectivity is lost, while the ethernet status remains "connected" and even the IP address is still there.
A "Renew DCHP Lease" gives me another 10 seconds of Internet connectivity, after that same problem.
I changed cables, just to be sure. Even though the PC's are working fine with the original cable.
I've reset the modem a 100 times already.
Any suggestion would be greatly appreciated!

Solution was simple, just leave all PC's turned off for a day. The modem "forgets" the MAC addresses and all works fine.

"Which Firewire cable should I purchase to connect a late 2006 Intel-based iMac with a 400 port to a Mid 2010 IMac with an 800 port?"

“Which Firewire cable should I purchase to connect a late 2006 Intel-based iMac with a 400 port to a Mid 2010 IMac with an 800 port?”

To connect both iMacs, you need a FireWire 400 to 800 adapter, and a FireWire 400 cable, so you will be able to connect both Macs

Connecting External Speakers to My Intel-based iMac

Hello everyone,
I have a 24-inch, white, Intel-based iMac. I also have a pair of wonderful sounding old Mission speakers that are not self-powered, and I was wondering if anyone knew whether the iMac's internal amp can drive them. Would I connect via the headphone port? And if so, is there a connector that I can buy to patch the speaker wires to a one-eighth inch pin to do the trick?
Regards,
Gregory

I also have a pair of wonderful sounding old Mission speakers that are not self-powered,
and I was wondering if anyone knew whether the iMac's internal amp can drive them.
*No way!* The iMac's 24 watt internal amp is NOT connected to the headphone output;
that's only for the internal speakers. The headphone output is spec'd at 1.6 Vrms max
with an output impedance of up to 24 ohms -- so, Apple only guarantees that it can
deliver 0.1 watt to an external load. In reality, the output impredance is probably less
than 24 ohms, so it will probably deliver a little more than that -- but the maximum
power output is still gonna be well under 1 watt. Headphones, yes ...speakers, NO!

How do I fax from my Intel-based iMac through a shared network fax?

The Intel-based iMac no longer has a built-in modem, so sending a fax from it is impossible. However, I set up fax sharing on my older (wiser and more mature) iMac, through a shared computer. The problem is that when I go to fax from my Intel-based iMac, it tells me that it cannot find a modem. I don't understand why it won't simply go through the shared fax on the network. I realize that it doesn't have an internal modem. That is why I am telling it to go through the network fax/printer that I set up. It won't listen. Kids!
As it stands, If I want to fax an InDesign document, for example, I have to export it to a pdf and move it (via the network) to the older iMac. This is time consuming and cumbersome. But, if the new iMac is incapable of performing properly over the network, what other choices are there?
If anyone knows of a way to fix this, I'd appreciate knowing. I am looking for the most efficient, time-saving way. Going online to find a faxing service, free or not, is not an option as that is just adding more steps.
Thanks very much.

I have been faxing from my Leopard machine through the shared internal fax modem on a Tiger machine across the room ever since I bought it and it worked fine. Until now. Apparently the 10.5.7 upgrade broke something, because it no longer works. I get this error message:
"A really really real fax number was not provided"
and then the document is deleted from the queue. I tried resetting the print system, as suggested elsewhere, but that still doesn't work.

Windows drivers for Intel-based iMac

Hi,
I have installed Windows XP Home on my new Intel-based iMac. Windows and Windows-based applications run fine, but there seem to be missing drivers that prevent the computer from connecting to the internet when it is running Windows (we have a DSL cable modem); audio drivers are missing, too. Where, and how, can I download and install these missing drivers? Thanks for any advice or hints!

You didn't say if Windows XP was installed in Boot Camp or Parallels.
If it's in Boot Camp make sure you used the right one. There are two versions of Boot Camp, one for Windows XP and one for Windows Vista. You have to run the driver installation CD in Windows after Windows is installed in Boot Camp.
If you're using Parallels make sure that the Windows Tools are installed by changing the window to OS Window mode and running Install Tools from the Action menu in Parallels.

What can happen to an intel-based iMac when a power outage occurs while it is on and I unplug it to avoid a surge when power comes back?

The power went out today, while I was using my intel-based iMac (2008) and I rushed to unplug the power from the wall, before the poser could surge back on. Did I do damage?
I have a surge protector that it was plugged into, but I thought just to be safe I should unplug!
Thanks, Group!
artdough

Good point!
Art a surge protector (a good one) is designed to provide contant power to the devices that are plugged into it. This is good in the event of a surge of power up or down however in the event of a complete power outage they're of no value.
A UPS (Uninteruptable Power Supply) is just that, it has surge protection like a surge suppresor however it also has a battery integrated into it. The battery is designed to provide enough power for a user to do an orderly shutdown. In addition most UPS's can also plug into your iMac via a USB cable. Then you can set energy saver preferences that you cannot see now. For example you can set how long the computer should run in the event of power going off. You can also set if you want the computer to reboot or not when the power comes back on etc. For about $100 you can get a fine UPS that will add an additional layer of protection for your computer and give you extra peace of mind.

My old Intel-Based iMac is no longer recognizing USB wired input devices; it only recognizes Bluetooth. What happened?

My friend's old Intel-Based iMac is no longer recognizing USB-wired input devices (Kensington TrackBall, Logitech Mouse) plugged into any USB slot at the back of the computer.
They were working before and for many years.
All of a sudden, A pop up window came up. IT said no Bluetooth mice could be found. We don't know what set off that window to pop up and look for a WL mouse. It never has before in the 5 or more years my friend has been using this computer.
I supplied a wireless Apple mouse and his is back running again.
But want to know why his USB-input devices (Except his keyboard) are not being recognized. He would prefer to use his Trackpad (Wired), but can't find anything in SYstem PReferences to allow that. The computer only seems to want a Bluetooth input device.
Anyone have an idea what happened and if this can be reversed?
I think he is still running Mac OS X 10.5.8.

Hi Carol, lets try this...
reset FW bus, same goes for USB reset...
Reset the Firewire bus
If your Firewire or USB isn't recognizing any device. A solution which has worked for some whose hard drive became invisible in 10.4 was simply to follow these four steps to reset the Firewire/USB bus:
1. Shut the machine down.
2. UNPLUG the power lead to the computer and any firewire/USB drive/devices.
3. leave it for 10 minutes.
4. Connect back up and reboot.

Then boot from that on your computer and install
You need an internet connection to install via Recovery mode

Convert an iMac G5 PPC to Intel Based iMac early 2006?

I have been working with Macs for some time and I know how annoying their hardware will only work for one series of computers and that's it. I was given an iMac G5 2004 for free and when looking to replace the motherboard I realized that it only uses DDR memory, terrible. I know they have 17" Intel based iMac G4 computers and figured with an iMac there are few parts you need to worry about. I would need to change out the LCD screen or connector and rewire it, I have hard drives that will work, I will need an Intel Core Duo processor (can pick a working one up real cheap), Motherboard will cost me $100, and I assume the DVD/CD drive is universal and will work with the Intel board. Now my concern is the power supply and the LCD inverter. That is pretty much all there is to these machines.
Now why don't I just buy a 2006 iMac? Because where is the challenge in that? Has anyone ever attempted this conversion? Money is not a problem, I enjoy moding and having little projects like this. I have a flat screen eMac with an LED LCD screen, I have a G4 with Mac Mini guts, I have a Gen 1 Apple TV running 10.5... you get the idea. I am tearing the machine apart now I just need to find the proper information, Google has failed me. I assume the 2006 MOBO should be a direct fit because the form factor is almost identical. USB and other slots look to be the same, if not I can bust out the plastic fill and Dremel. Anyone have any thoughts besides that this is a dumb idea?
If I go ahead with this I plan on doing a write-up. In theory, these seems like a very simple conversion just because everything is based around the MOBO and the parts that would need to be replaced I have or are inexpensive. I figure the project would cost me around $300. I run a tech shop and get parts dirt cheap. Any ideas or information would be great as I typically don't work on 2004 models, thanks!
Please no flaming, if you intend to flame just go bother someone else thanks!

You also have to consider to port locations, and if the ventilation is enough for the logicboard.
Furthermore a Mac mini uses a SATA bus that is more geared towards powering 2.5" drives, not 3.5" drives. Though I've seen some who hacked an eSATA on a Mac Mini on the net. Don't forget a CoreSolo or CoreDuo Mac Mini won't give you much of an advantage over the G5. Core2Duo 2.2 Ghz or higher is better unless you still depend on numerous non-Universal applications.

Mac os 9 on intel-based imacs

I used to own a Windows computer and had a lot of software for it. then I moved and bought a Mac. I tried to install the software on it but it didn't work. on the box it said it needed os 8 or 9. how do I install mac os 9

You want to install OS8 or OS9 on a new Intel-based iMac ???
That ain't gonna happen. And it won't run Windows 3.1 either or accept floppy disks either.
It is not a good idea to run any unsupported system and that includes any Macintosh system that PRE-DATES the date of manufacture of your computer.
With programs like VMware or Parallels or BootCamp or Virtual PC or other emulators it IS entirely possible to install just about any version of Windoze on just about any Macintosh.

Older printer set ups on Intel-based iMac

I just bought a new iMac with Intel inside running OS 10.4.4 and I bought a new AsanteTalk adapter. I have tried to hook up an Apple Laserwriter 12/640 PS as well as an Epson Stylus Color 800. The drivers are in the iMac, but I can't get the machine to see either printer using AppleTalk through a direct Ethernet connection or through an Ethernet hub. Is this a new problem because of the Intel-based iMac? Has anyone tried using older printers with the new Intel-based iMac?

Intel-based iMac stuck in grey screen with spinning wheel. SMC::smcReadKeyAction ERROR THOP kSMBadArgumentError(0x89)

Hi guys,
since yesterday my Intel-Based iMac doesn't boot normally, its stuck in grey screen with a spinning wheel.
Its an Intel-based iMac 21.5'' purchased in 2011, and i recently (2 months ago) upgraded it to Mavericks.
-2 weeks ago, i installed smcFanControl app
-Tried start up in Safe Mode by holding Shift but its not working. i think i hear fans are working more than they were before the problem occurs.
-entered Single User Mode and i get an error
SMC ::smcReadKeyAction ERROR THOP kSMCBadArgumentError(0x89) fKeyHashTable=0x0xffffff8029fa1000
-followed some instructions found online, but can execute the correct commands in SingleUserMode
tried to remove FanControl as explained here: http://apple.stackexchange.com/questions/110667/errorr-kernel-smcsmcreadkeyactio n-in-console
any ideas what may caused this and how can i fix this?
Thanks in advance

Take each of these steps that you haven't already tried. Stop when the problem is resolved.
Step 1
The first step in dealing with a startup failure is to secure the data. If you want to preserve the contents of the startup drive, and you don't already have at least one current backup, you must try to back up now, before you do anything else. It may or may not be possible. If you don't care about the data that has changed since the last backup, you can skip this step.
There are several ways to back up a Mac that is unable to start. You need an external hard drive to hold the backup data.
a. Start up from the Recovery partition, or from a local Time Machine backup volume (option key at startup.) When the OS X Utilities screen appears, launch Disk Utility and follow the instructions in this support article, under “Instructions for backing up to an external hard disk via Disk Utility.” The article refers to starting up from a DVD, but the procedure in Recovery mode is the same. You don't need a DVD if you're running OS X 10.7 or later.
b. If Step 1a fails because of disk errors, and no other Mac is available, then you may be able to salvage some of your files by copying them in the Finder. If you already have an external drive with OS X installed, boot from it. Otherwise, if you have Internet access, follow the instructions on this page to prepare the external drive and install OS X on it. You'll use the Recovery installer, rather than downloading it from the App Store.
c. If you have access to a working Mac, and both it and the non-working Mac have FireWire or Thunderbolt ports, start the non-working Mac in target disk mode. Use the working Mac to copy the data to another drive. This technique won't work with USB, Ethernet, Wi-Fi, or Bluetooth.
d. If the internal drive of the non-working Mac is user-replaceable, remove it and mount it in an external enclosure or drive dock. Use another Mac to copy the data.
Step 2
If the startup process stops at a blank gray screen with no Apple logo or spinning "daisy wheel," then the startup volume may be full. If you had previously seen warnings of low disk space, this is almost certainly the case. You might be able to start up in safe mode even though you can't start up normally. Otherwise, start up from an external drive, or else use the technique in Step 1b, 1c, or 1d to mount the internal drive and delete some files. According to Apple documentation, you need at least 9 GB of available space on the startup volume (as shown in the Finder Info window) for normal operation.
Step 3
Sometimes a startup failure can be resolved by resetting the NVRAM.
Step 4
If you use a wireless keyboard, trackpad, or mouse, replace or recharge the batteries. The battery level shown in the Bluetooth menu item may not be accurate.
Step 5
If there's a built-in optical drive, a disc may be stuck in it. Follow these instructions to eject it.
Step 6
Press and hold the power button until the power shuts off. Disconnect all wired peripherals except those needed to start up, and remove all aftermarket expansion cards. Use a different keyboard and/or mouse, if those devices are wired. If you can start up now, one of the devices you disconnected, or a combination of them, is causing the problem. Finding out which one is a process of elimination.
Step 7
If you've started from an external storage device, make sure that the internal startup volume is selected in the Startup Disk pane of System Preferences.
Start up in safe mode. Note: If FileVault is enabled, or if a firmware password is set, or if the startup volume is a Fusion Drive or a software RAID, you can’t do this. Post for further instructions.
Safe mode is much slower to start and run than normal, and some things won’t work at all, including wireless networking on certain Macs.
The login screen appears even if you usually log in automatically. You must know the login password in order to log in. If you’ve forgotten the password, you will need to reset it before you begin.
When you start up in safe mode, it's normal to see a dark gray progress bar on a light gray background. If the progress bar gets stuck for more than a few minutes, or if the system shuts down automatically while the progress bar is displayed, the startup volume is corrupt and the drive is probably malfunctioning. In that case, go to Step 10. If you ever have another problem with the drive, replace it immediately.
If you can start and log in in safe mode, empty the Trash, and then open the Finder Info window on the startup volume ("Macintosh HD," unless you gave it a different name.) Check that you have at least 9 GB of available space, as shown in the window. If you don't, copy as many files as necessary to another volume (not another folder on the same volume) and delete the originals. Deletion isn't complete until you empty the Trash again. Do this until the available space is more than 9 GB. Then restart as usual (i.e., not in safe mode.)
If the startup process hangs again, the problem is likely caused by a third-party system modification that you installed. Post for further instructions.
Step 8
Launch Disk Utility in Recovery mode (see Step 1.) Select the startup volume, then run Repair Disk. If any problems are found, repeat until clear. If Disk Utility reports that the volume can't be repaired, the drive has malfunctioned and should be replaced. You might choose to tolerate one such malfunction in the life of the drive. In that case, erase the volume and restore from a backup. If the same thing ever happens again, replace the drive immediately.
This is one of the rare situations in which you should also run Repair Permissions, ignoring the false warnings it may produce. Look for the line "Permissions repair complete" at the end of the output. Then restart as usual.
Step 9
Reinstall the OS. If the Mac was upgraded from an older version of OS X, you’ll need the Apple ID and password you used to upgrade.
Step 10
Do as in Step 9, but this time erase the startup volume in Disk Utility before installing. The system should automatically restart into the Setup Assistant. Follow the prompts to transfer the data from a Time Machine or other backup.
Step 11
This step applies only to models that have a logic-board ("PRAM") battery: all Mac Pro's and some others (not current models.) Both desktop and portable Macs used to have such a battery. The logic-board battery, if there is one, is separate from the main battery of a portable. A dead logic-board battery can cause a startup failure. Typically the failure will be preceded by loss of the settings for the startup disk and system clock. See the user manual for replacement instructions. You may have to take the machine to a service provider to have the battery replaced.
Step 12
If you get this far, you're probably dealing with a hardware fault. Make a "Genius" appointment at an Apple Store, or go to another authorized service provider.

Intel based iMac Seems to Be Getting Slower

I have one of the recent Intel based iMac's. Everything seems to run fine but the system is starting to slow down. I doubt it's mechanical, I do IT work for a living so I'm probably much more sensitive to it then most people are. I'm just wondering what might be causing it? For example system startup seems to have gotten noticeably slower since I purchased back in may of this year. Normal application use seems the same, but if I run a old powerpc based game, I need to restart the machine after I close it, otherwise the machine crawls.
The system has the latest OS updates, 4GB Ram, 2.8GHZ processor, Geforce 8800GS 512MB. I'm using a wired Apple Pro Keyboard (white keys, right before the aluminum release), Logitech MX518 Wired Mouse. The 4GB of ram is not standard, but a matched pair of 2GB chips from Other World Computing.
I use a program called Xslimmer to weed out files I don't need to save space. I don't have any really large files on the system, just thousands of smaller photos & documents. Free space on the hard disk is 318.79GB. I have 3 login items: CoverSutra, iTunes Helper, and EyeTV Helper that run automatically on startup.
Any suggestions? Should I consider an application like Drive Genius, Spring Cleaning, etc? I did install the Logitech Control Center (don't know how to remove it) but I don't use it, it's not in my startup items, and doesn't see the mouse anyway.
Thanks!

Try starting without the eyeTV stuff. (I've noticed my Macbook which used to shut down in exactly 3 seconds now takes 8 seconds, and this began the day I installed eyeTV).
I would then try starting without CoverSutra. You need to eliminate things one by one.

How do I connect my intel based imac to a LG LCD tv?
