How to downgrade my new iMac to OSX 10.4

I have just received my new iMac 24" (intel, 3,06 Ghz) with 10.5.4 pre-installed.
Due to specific driver problems with an important printer I need to downgrade to 10.4.x but none of my "old" disks seems to work. They either do not recognise the hardware or just keep on rebooting.
Anybody an idea on how to do this?
Thanks,
Peter

Hello and Welcome to Apple Discussions.
The general rule is that you can't:

I know that the first revision of Aluminium iMacs probably could be downgraded as the early ones were shipped with Tiger.
Could you post details of the driver issue to see if we can help with that?

BTW this forum is for the much older iMac (Flat Panel) models

How to downgrade a new iMac (model 12.1) to SnowL

Hi I just got a new iMac with the latest version of Lion but I want it to run under SL, since many of my prgrams won't work on Lion.
I got the original SL instalation disc as well as a Time Machine Backup HD (with Leopard from my old iMac).
Regards

Your new iMac may not be able to boot into Snow Leopard. Although the currently-shipping models were first released with Snow Leopard, and so one might assume that they can boot into Snow Leopard, those being sold now might have received minor changes to their hardware or firmware which prevent Snow Leopard from fully functioning or booting these machines at all.
I know that I've had mixed success with recently-purchased iMacs and Snow Leopard. So I suggest that you do not remove the Lion installation, but instead use an external hard drive or a partition of the internal hard drive for any attempt to install Snow Leopard.
If you have a "full retail" Snow Leopard installation DVD, just pop it into your iMac's optical drive (after formatting the external drive/partitioning the internal drive using Disk Utility, of course), restart while holding the C key on your keyboard, and be sure to choose the external drive/correct internal drive partition on which you want to try installing Snow Leopard.

I am using a new imac with osx lion 10.7.5 and have bought a copy of Apple iLife 11 on dvd a so that I can install iWeb and idvd, when I click on install iLife I get a message saying "iLife.kpg was signed with an invalid certificate

I am using a new imac with osx lion 10.7.5 and have just bought Apple iLife 11 on dvd so that I can install iWeb and iDVD, as macs no longer ship with these apps. When I click on install iLife I get a message saying "iLife.kpg was signed with an invalid certificate.
Next problem is that when moving through the installer and get to custom install, as I only want to install iDVD and iWeb, I am presented with the option to install iDVD, Sounds & Jingles and iWeb, but not sure what is going on with the other 3 options iLife Support etc, they seem to be greyed out but still look like they may install over the top of the newer versions already on my imac. Is it ok for me to just go ahead and hit install? Or do I have a problem?

Yep, just install iDVD (plus sounds and jingles) and iWeb if you want it (but note that iWeb apparently won't work if you upgrade to Mountain Lion).
Then use Software Update to get any late iDVD updates.

Wacom Intuos Tablet and Pen not working on new iMac with OSX 10.9.4

Hi there, I've been using an A3 Wacom Intuos tablet and pen for many years now on a 2006 iMac for my illustration work, but I cannot get them to appear or work on my new iMac with OSX 10.9.4. I think they are the original Wacom Intuos tablet and pen. Does anyone know if they are just out of date now and aren't supported on the new OSX 10.9.4? Any advice would be greatly appreciated as I need to work and it's frustrating!
Many thanks,
Steve

I have done as you suggested; I uninstalled PSE 11 and set my wife's account up as admin and reinstalled from there. Still have the same problem with my wife's account, but when I went to mine it is working correctly. Any ideas on why that would be? I'm sure it should work on both accounts. I have 2 accounts on my Mac Mini running OS X 10.6 Snow Leopard and it works on both.
Thanks for your help; at least it's working on my account so that's a great improvement.

How do I run new iWork on OSX 10.6?Thanks

How do I run new iWork on OSX 10.6?Thanks

iWork is licensed for the system, not the user, so if this user is on the same system, there's nothing you need to deactivate. If this copy of iWork is installed on a different computer and you want to install on this second one, just delete the iWorks apps from the first system.

Help, please! Any advice on how I link my new iMac and my new itunes software with existing external harddrive containing my entire itunes library?

Hello!
It should be a matter of
Quiting iTunes first if it's running
Connecting your external harddrive to your Mac, use the Finder to browse to it
Find your iTunes folder on the ext HDD and double-click on iTunes Library.itl
If you have any trouble with this, please let us know.

Looking to downgrade my new iMac to mountain lion HELP

Can't seem to find the right help. I run Mountain Lion on my laptop and I love it. I recently bought a new iMac and was very excited at my new work station at home only to discover Mavericks is unusable.
I'd like to go back to Mountain Lion. Yes, the iMac came with Mavericks loaded, but this OS is fail. I need to be able to work, and work fast with out having to be my own IT support as well. I need my tools too, track pad, safari, etc.
How can I downgrade? Is it going to cost me? Heck, is it possible? Support has been unhelpful. If I can't downgrade I am going to take this shiny paper weight and exchange it for a PC and save money. Why pay a premium when the one feature that demanded the premium is unusable? I am NOT a happy apple customer. After 25 years I am about to walk away for good.

You may not be able to "downgrade" the OS on a machine that shipped with Mavericks installed.
The normal method would be to erase the drive and then install 10.8.5. You'll need to buy a redemption code at the Apple Store to use at the App Store.

How noisy/quiet is new iMac with Retina 5K display?

How noisy/quiet is new 5K iMac compared to the standard display versions? I returned three 27" iMacs (3.5GHz Quad-core Intel Core i7) back in May because they were too noisy for me. Is this 5K machine any different?

imac 5k sadly has a very active fan, especially in the combination of i7 and the amd r9 m295x gpu (4gb).
check the forums (wow, cod etc.) where many people are currently complaining and returning their mac (me as well considering it).. while gaming the fan speed is at 2700 rpm which is around 38 db (very loud!) and the gpu is 105C (not fahrenheit!).
all processor (cpu) intensive tasks like handbrake, rendering etc. will make the i7 go warm and the fan go loud.
all graphics (gpu) intensive tasks like any game will make the amd m295x go hot and the fan go very loud.
regular surfing, photoshop etc. is not affected!
in normal mode, it's always at 1200 rpm where it is not audible to me.
if you want it as quiet as possible go with the i5 and the cheaper graphics card (290x).
just be aware that this is the loudest imac or even mac ever (louder than current mac pro) and I'm not sure if constant heat (105C) is affecting life expectancy and I've been having them since 1991.

How do i get new imac to work with windows

I'm new to the imac world, how do I get it to work with windows

If you are talking about MS Windows then you need to launch either Boot Camp or run it in Virtualization app such as Parallels or VM Fusion. You also need a valid license of MS Windows.However if that is not what you mean then you must be much more specific. For example:
"I want to share some files between my PC running Windows 7 and my new iMac running 10.9.3, how do I go about that?"

How do I wipe new iMac (3/2012) H.Drive and reinstall Lion and the preinstalled application?

I just bought a 27" iMac (3/2012) and migrated the data from my Mac Pro into the new iMac. It's now overloaded with the settings and files that I should have just put on an external drive, but I didn't. I want to erase everything and start with what OS and applications when I purchased it. It is running Lion OS X Version 10.7.3. Before the app store I understood how to do this when there was a recovery disc for the OS and Applications but need help on how to get it back to a clean new system (and I do not need to save any settings or information on the new imac).
Really appreciate the help
CJ

Install or Reinstall Lion from Scratch
If possible backup your files to an external drive or second internal drive.
Boot to the Recovery HD:
Restart the computer and after the chime press and hold down the COMMAND and R keys until the menu screen appears. Alternatively, restart the computer and after the chime press and hold down the OPTION key until the boot manager screen appears. Select the Recovery HD and click on the downward pointing arrow button.
Erase the hard drive:
Select Disk Utility from the main menu and click on the Continue button.
After DU loads select your hard drive (this is the entry with the mfgr.'s ID and size) from the left side list. Note the SMART status of the drive in DU's status area. If it does not say "Verified" then the drive is failing or has failed and will need replacing. SMART info will not be reported on external drives. Otherwise, click on the Erase tab in the DU main window.
Set the format type to Mac OS Extended (Journaled.) Click on the Erase button and wait until the process has completed.
Quit DU and return to the main menu.
Reinstall Lion: Select Reinstall Lion and click on the Install button.
Note: You can also re-download the Lion installer by opening the App Store application. Hold down the OPTION key and click on the Purchases icon in the toolbar. You should now see an active Install button to the right of your Lion purchase entry. There are situations in which this will not work. For example, if you are already booted into the Lion you originally purchased with your Apple ID or if an instance of the Lion installer is located anywhere on your computer.
