Installing OS X 10.5 on to iMac 24inch 2.93Ghz
Our company haS purchased a new iMac 24inch 2.93Ghz, preinstalled with Snow Leopard. In our company there are some applications which are not compatible with Snow Leopard. As such I want to re-install this iMac with OS X 10.5. I have tried to do this with about 5 different installation DVDs for Leopard 10.5, however none of these will boot up into the installation menu.
Is the iMac 24inch 2.93Ghz compatible with an older version OS? Does anyone have any suggestions of doing a clean installation of OS X 10.5?

No, you can not use different or older versions: see > http://support.apple.com/kb/HT2186
+Important: Even though one version of system software may be identical in version number to another, the software may not be exactly the same. For example, you may have a retail version of the Leopard install disc (Mac OS X v10.5) and your computer perhaps came with Mac OS X v10.5. Your computer may have additional software specific to it included on its software disc (Mac OS X 10.5) which may not be present on the retail Mac OS X v10.5 disc. See this article for more information.+

Sorry, you can not: see > http://support.apple.com/kb/HT2681
+Computer-specific versions of Mac OS X include special software that lets Mac OS X work seamlessly with the new model's hardware, and is required for the computer to work correctly. That's why you usually can't use an earlier version of Mac OS X than the one that came with the computer. The special software is not included in Mac OS X reference releases or software updates that were released before the model was introduced.+

I have just installed a 2TB time capsule on my iMac i7, it see my second 1TB hard drive but the 256 SSD doesn't come up in the list of hard drives I can back up. How can I enable the time machine to see my first SSD 256gb hard drive?
iLife is preinstalled on all the Macs. If you purchased iLife in the App Store or your computer came without DVDs, open App Store > Purchases and download the applications. If your Mac came with discs, insert the Applications DVD and install iLife applications

I have an iMac 5.1 which is running OSx10.5.8 - it runs very slowly and I can't find if there is a particular problem. In the process, I have tried to install 10.6 [I have a new iMac] and the 5.1 won't accept the install discs.
As you have discovered... you cannot use the install discs from another Mac...

How To Install 10.5 On A 1st Gen iMac G5
Hi All
1:40am and I give up and ask for help!
I am trying to install 10.5 on my old iMac G5 but am having massive problems.
I wont bore you all with the history but just descibe the position I now find myslef in and hope someone can help me get this machine up and running.
So, now I know that my machine can't read dual layer disks and that I have to use target mode to my brand new MBP running the latest version of 10.5.
The iMac (please don't ask why) now has a formatted HD with nothing on it.
It will boot into 10.4 on the install DVD OK but I can not find out how to link the two machines and thus use the DVD drive on the MBP to do the install.
I have tried turning the iMac on with the 10.4 DVD in the slot and holding down T but that has no effect ... just boots into the 10.4 installation routine.
I have looked around in the 10.4 Utilities menu to try and find n option to boot into target disk mode but can not see it in startup disk or disk repair. Might be too late at night but ...
Any help with this gratefully received.
Thanks
DavidUnless there's something wrong with your hardware the machine should be able to read dual layer disks, but the target mode should work for installation as well.
To boot off the leopard DVD on the iMac, press and hold "C" at bootup with the DVD in the drive, not "T". If this doesnt work (as you mentioned the thing has a hard time reading dual layer DVDs), then do the following to boot off of the DVD in Target Disk mode with the DVD in your MacBook Pro.
With the DVD in the drive, boot the MacBook and hold "T" and it will have the firewire symbol dancing on the screen. Connect the MBP to your iMac using a firewire cable. Then boot up the iMac and hold "options" down until it displays a list of drives that can be booted from. The Leopard DVD in the MacBook should be displayed (so should your MBP hard drive, but dont boot off of this). Select the installer DVD and press go (might be a bit laggy, so be patient), and it should boot into the installer. -
After installing the new Yosemite OS on my iMac I can no longer send email. I can receive email, but not send. I use gmail and can send email on the gmail (google) site, but not on "mail" on my iMac. Any others with this problem? What should we do?
My gmail, which is correctly configured for Mail with gmail SMTP and Google IMAP, works for awhile on Mail, which I leave open while working on other applications. But several times a day I get msg from Google: "We recently blocked a sign-in attempt to your Google Account" . . . and requiring me to verify my account details, re-enter passwords, confirm security settings (or change them from "disable" to "enable less secure methods" and so on). In Mail I also have tried "taking all accounts online", and re-entering my gmail password inside Mail account settings. These steps successfully re-set comms between gmail and Mail ... for awhile, then it happens again. Enough occurrences over a work day that I just quit Mail and revert to accessing gmail directly. Apple Care advisor and an Apple knowledge base article say that Apple can't deal with this, as gmail is third-party app, and they refer me to gmail, and so far I've found nothing helpful there.
From today I also have several instances of a window saying "Mail has unexpectedly closed" and asking me to Re-open it.
I also use Yahoo mail, which stops working with Mac Mail at the same time as gmail, but I do not receive notices to re-verify from Yahoo.
I recently upgraded from Mavericks to Yosemite. The Mail problem happened occasionally with Mavericks but is far more frequent with Yosemite. -
hi im having huge problems trying to install flash for my mac 10.5 imac, iv gone through the internet and tried all of the solutions, everytime i try to install flash it says cant read the download file, or it just wont install, anybody plz help!
iv unistalled flash, iv checked plug ins it just wont work,It would have been a great help to know precisely what Mac you have, so some of the following may not apply:
You can check here: http://www.adobe.com/products/flash/about/ to see which version you should install for your Mac and OS. Note that version 10,1,102,64 is the last version available to PPC Mac users*. The latest version,10.3.183.23 or later, is for Intel Macs only running Tiger or Leopard, as Adobe no longer support the PPC platform. Version 11.4.402.265 or later is for Snow Leopard onwards.
(If you are running Mavericks: After years of fighting malware and exploits facilitated through Adobe's Flash Player, the company is taking advantage of Apple's new App Sandbox feature to restrict malicious code from running outside of Safari in OS X Mavericks.)
* Unhelpfully, if you want the last version for PPC (G4 or G5) Macs, you need to go here: http://kb2.adobe.com/cps/142/tn_14266.html and scroll down to 'Archived Versions/Older Archives'. Flash Player 10.1.102.64 is the one you download. More information here: http://kb2.adobe.com/cps/838/cpsid_83808.html
You should first uninstall any previous version of Flash Player, using the uninstaller from here (make sure you use the correct one!):
http://kb2.adobe.com/cps/909/cpsid_90906.html
and also that you follow the instructions closely, such as closing ALL applications (including Safari) first before installing. You must also carry out a permission repair after installing anything from Adobe.
After installing, reboot your Mac and relaunch Safari, then in Safari Preferences/Security enable ‘Allow Plugins’. If you are running 10.6.8 or later:
When you have installed the latest version of Flash, relaunch Safari and test.
If you're getting a "blocked plug-in" error, then in System Preferences… ▹ Flash Player ▹ Advanced
click Check Now. Quit and relaunch your browser.
You can also try these illustrated instructions from C F McBlob to perform a full "clean install", which will resolve the "Blocked Plug-in" message when trying to update via the GUI updater from Adobe.
Use the FULL installer for 12.0.0.44: Flash Player 12 (Mac OS X)
And the instructons are here: Snow Leopard Clean Install.pdf
(If you are running a PPC Mac with Flash Player 10.1.102.64 and are having problems with watching videos on FaceBook or other sites, try the following solution which fools the site into thinking that you are running the version 11.5.502.55:)
Download this http://scriptogr.am/nordkril/post/adobe-flash-11.5-for-powerpc to your desktop, unzip it, and replace the current Flash Player plug-in which is in your main/Library/Internet Plug-Ins folder, (not the user Library). Save the old one just in case this one doesn't work. -
I'm installing windows 7 64-bit on my imac which I've done before but I get a message that the partition is GPT even after I format the bootcamp partition. I just upgraded my hard drive to a 3tb and I'm allocating 1tb for windows. How can I fix this?
No easy fix for a few reasons:
1) Bootcamp requires a hybrid MBR for the partition table. That is: both an MBR and a GPT partition table at the same time with the GPT one having all partitions and the MBR one having only the ones that are relevant, but at most 4 of them (including the protective partition and the Macintosh HD one). Which leads us to:
2) The MBR part of the hybrid partition table cannot work with 3TB hard drives. MBR is limited to 2TB.
I am working on a small EFI app that can boot Windows in EFI mode on a Mac and that would mean that you can go GPT only on your system. The progress of the app is slow due to the nature of EFI and for now requires that you do an unattended Windows install with slipstreamed graphics drivers, but we are adding VGA loading on top of EFI quite soon after the rest of the app stabilises. The status of the app is documented at:
Win7 x64 booting natively via EFI (no bios emulation)
Windows does actually successfully boot in EFI mode on most Macs (anything with a 64bit EFI should work), but does not have graphics support even if you load the driver due to the VGA pci registers not being set by the firmware. Furthermore, in Setup and Safe Mode, Windows uses VGA instead of GOP which is a failure by design since VGA is a BIOS standard and not really compatible without hacks with EFI. Other EFI implementations also add VGA compatibility at a high cost to the firmware complexity for the VGA cards available on the market that don't actually contain anything in their ROM except the VGA BIOS.
My recomendations:
1) Install on a second smaller hard-drive; or
2) Wait for the EFI app to come out officially and use that to boot Windows Vista SP1 x64 and Windows 7 x64 (RTM and SP1) in the native EFI mode.
3) Wait for Windows 8 which supports VGA-less booting acording to the AMD presentation at UEFI Plugfest. -
Just done a replacement of the pata DVD drive (its new and is working ok), and a fresh clean install of Snow Leopard with all updates, iMac 5.1 behaves strange, sometimes I start Google Chrome and look at youtube videos the computer freezes and shuts down immediately,
I believe its related to overheating ?
iStat Pro shows GPU diode temp at 66 C, CPU at 48 C, Fan rpms is around 1000
Any ideas somebody ?
The hard disk has been previously checked with state of the art techniques that have confirmed that the hard disk drive is in perfect condition.1.5-3 minute boot up as opposed to 15-20 seconds
And
why it takes a long time to load a lot of things.
I have restored this
from a time machine partition.
TimeMachine is only a backup and restore, it won't fix issues in software and according to your information, doesn't even optimize the restore for best performance on boot hard drives.
What you need to do to regain your speed is to understand how your machine works
Why is my computer slow?
Fix any and all issues in software following this list of fixes
..Step by Step to fix your Mac
Then follow this defrag method I've outlined
How to safely defrag a Mac's hard drive
Most commonly used backup methods
There shouldn't be need to reinstall OS X fresh unless your having file structure issues which if they are should appear when in the Steps, which then a zero erase and install will cure as well as any bad sector issues, the defrag step wouldn't be necessarry on a freshly installed system obviously as the files are written all together, not in portions all over the drive.
Hope this assists. -
Cannot install Win 8 on a late 2013 iMac using bootcamp on 10.9
I'm trying to install Win 8 on a late 2013 iMac (purchased a couple of months ago)
I have a win 8 pro DVD, but obviously there is no DVD in this iMac. I usally use the DVD drive in my older 2009 iMac for any disk based installs but I can't appear to use it here.
I followed the instructions and downloaded a Win 8 Pro ISO from Microsoft to use with my authentication code, created a bootable USB using bootcamp, created the partition and rebooted. Once I'd entered the code I get to the install location but it says I cannot install on the partition created by bootcamp. Even if I format the partition it says I need a GPT drive but I have MBR, so won't let me install.
I tried several suggestions including creating aprtitions in various other programs and once I even got past that screen, but as soon as it tried to install I got another error saying the MBR was formatted incorrectly and it failed.
I had no issues installing Win 7 via bootcamp on the older iMac, but this one has me stumped. I used to think I knew a bit about computers, but I'm fairly new to Mac related issues as the older iMac has always just worked.
Any help would be greatly appreciated.Hello,
I just installed Windows 8.1 on my Late 2013.
There are just a couple of things I had to do that deviated from the Boot Camp Installation Manual.
1. I downloaded my copy of Windows 8.1 as an ISO image AND as a bootable USB from the Microsoft site.
Not sure why I did that but it came in handy because Bootcamp was taking a very long time to copy the ISO onto the USB stick..
The ISO copying seemed to freeze up, but it's likely that it was just taking a long time, probably 20mins.
So, instead of waiting, I took the contents of the the USB startup stick and simply moved them over to the stick that Bootcamp had formatted for the ISO copy (I cancelled that copy function and deleted any files that had copied but didnt complete).
Once that was done, the machine rebooted from the USB stick and began the normal Windows setup process.
All went very smoothly except that my mouse was not working.
2. To get around the mouse issue, I simply plugged in a MS USB Mouse and it worked immediately.
The Bootcamp manual advised that the way around this was to 'click in upper right corner and search for Bootcamp'. Problem was, it was nowhere to be found.
So, using my MS mouse, I navigated to the 'DESKTOP' icon in Win 8.1 and found File Explorer, which showed my USB stick connected along with Bootcamp and the MS Support File (i.e. All the Apple Drivers).
I began manually clicking on all the driver files until realizing that there IS a Bootcamp executable which will automatically install the drivers for the Nvidia card, keyboard, camera, mouse, etc....
Once that was done, my installation was completed.
The entire process took about an hour, but now that I've done it, it really shouldnt take much more than 45 mins.
I have the late 2013 iMAC, with the GTX780M and 1TB Fusion Drive i5 Quad Core.
For those who are leery about doing this, please note that I'm a PC 'lifer' and this is my very first go-around with doing anything on an Apple product.
It all went much more smoothly than I could have imagined, but if you are not a PC person, you might be a little challenged finding the Bootcamp in File Explorer or doing anything in Win 8.1 to get over these minor hurdles.
Good luck!
I'm looking forward to getting STEAM up and running to see how this thing games! -

I have just installed a new hard drive in my imac intel 20" (2006) and upgraded the memory and now the hard drive does not show up in the 'select destinations' folder of the install program. I can see the hard drive in the disk utilities window however it wont let me do anything.
It is a seagate 1TB SATA II drive however it is displaying it as a 7.3 TB.
If anyone has any suggestions I would be happy to hear them.
I have tried to erase and partition and get the same error message each time, 'Input/Output error'.
I have tried starting the thing with the install disk which is Mac OS X (Tiger?) which came with the computer. No good.
Anyone?Thats correct. I can see it in the list however when I attempt to erase it or partition it it's like it's not being found or recognised and it throws up the input/output error message. I am pretty sure that the sensor it attached correctly and it is a SATA drive. I can see all the infor regarding the drive when disk utility is open and it all looks good but I cant access it or do anything with it. It's taunting me!
The install disk is in the drive and the install program runs right up to the point where you have to select the location for the install and there is just nothing in the box where you have to select the hard drive icon.
I have my suspiscions about the drive but any help would be appreciated. -
Can not install OEM Windows 7 64 bit on iMac 24"
I have a late 2006 iMac 24" white. I have installed Lion with Boot camp 4.0. I am attempting to install Windows 7 64 bit OEM. At Step 3 "Install Windows" of the Installation and Setup Guide the system does not start the Windows 7 installer. Please Help!
I found another thread about running Windows 7 64 Bit on systems other than in a list provided by Apple. I ran the suggested Terminal Command with the following result:
george-halls-imac:~ georgehall$ ioreg -l -p IODeviceTree | grep firmware-abi
| | "firmware-abi" = <"EFI32">
Does this mean that I can not run 64 Bit Windows 7 on my system? Do I need to upgrade the firmware? Can I change this parameter and get the system to boot the Windows 7 install disk?

Sincerly AppleNoob92
p.s i have no experience in apple imac's at all never used before, but im kinda windows nerd so computers i understand but this imac make my insane, cant seem to find any solutions anywhere on the WWW....Your HD may be crashed, so you probably should use the oringinal install discs to run Apple Hardware Test in extended mode. If error codes appear this confirms a hardware failure. In addition you cannnot repair the HD using Disk Utility from the startup disk, you have to use the origninal Install discs that shipped with the computer or the most up-to-date version of OS X on a disc that you have.
