Can I restore an intel based iMac9,1 to OSX10.4?

Hi all,
I have 12 iMacs running 10.5 leopard. The library has asked me to roll them back to 10.4 so they are compatible with the booking system they use. They are intel based iMac9,1. I have got a 10.4.3 retail restore DVD, but that only works for PowerPC based iMacs. Is there a 10.4 restore DVD avaible for Intel based 9,1 iMacs?
Thanks,
Harry

Only iMac 7,1 and earlier shipped with Tiger. The Tiger retail installer discs will not work with them if they are Intel, and only the prebundled iMac Intel installer discs would install Tiger on them. All iMac G4s will work with Tiger retail, though some only had a CD drive, and those will require a Firewire DVD drive to install Tiger retail. All iMac G5s will work 10.4.6 retail, though those Powermac 8,1 could run 10.4.0 & 10.4.3 & 10.4.6 retail, and 8,2 could run only 10.4.3 & 10.4.6 retail. PowerMac 12,1 early models could run 10.4.3 retail & 10.4.6, only to later only support 10.4.6 retail after serial numbers xx544xxxxxx and higher where x can be any letter or number.

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.

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!

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.

Can i put a intel based hard drive in my ibook g4?

Im wondering if its possible to install a intel based hard drive in my ibookg4,and am wondering if it would be more reasonable to do that instead of buying a completely new computer.Any websites you could show me,or info you could give me would help me a lot.Thank you

There really aren't "Intel based" hard drives.
However, what your iBook needs is a 2.5" PATA hard drive. If you're looking to use a hard drive from, say, a MacBook, that won't work because MacBook hard drives 2.5" SATA drives. What was your plan, exactly?
You can check iFixit.com for instructions to replace the drive--it will take a few hours, and there's a LOT of screws involved, but the project is certainly doable.
Take a search through the boards for other similar topics & you'll find some good advice.

Can I use my Intel-based MacBook to boot into Windows 7 from an external HDD?

Okay, so I need to use Windows for some simple applications. Problem is, I don't have a Windows desktop anymore and while I have both Windows and Linux partitions along with Mountain Lion on my installed hard drive, I'm probably going to wipe said drive and just use the entire partition for Mountain Lion. That said, I'd like to use an extra hard drive I have lying around to boot Windows.
My questions are:
1. Does my MacBook support USB boot to Windows?
2. If my laptop does support this, can someone point me to a set of good reliable instructions to install Windows onto the external hard drive and boot into it by USB?
Thank you; have a blessed day!

You seem to have a triple boot system that was done using the 10.6 installer disk and a copy of rEFIt.
I know because I had the same thing once.
I can tell you what will happen if you decide to upgrade 10.7 or 10.8
1: The EFI and GUID is going to change, rEFIt hasn't been updated in ages since 10.7 started rolling out back in about June 2011. There will be adverse effects with rEFIt so I hear.
2: The 10.8 upgrader is going to barf at your triple boot system, it will upgrade the 10.6 partition but warn you that the 10.8 RecoveryHD partition (10.7 and 10.8 both install) that it normally installs at the very bottom of the drive will not be installed and you can't enable Filevault.
Intel Mac's can have only 4 bootable partitions on the drive, the 10.7+ installer is normally dealing with EFI, MacintoshHD, BOOTCAMP, RecoveryHD. It barfs at anything else it doesn't understand and will not install RecoveryHD partition, which on a non-Internet Recovery capable hardware is required to reinstall the currently upgraded OS X operating system version. But you can always go back to the 10.6 disks and wipe and restore that way or via 10.6 USB boot key.
http://www.maciverse.com/install-os-x-snow-leopard-from-usb-flash-drive.html
So with 10.7+ you'll have to use something like Carbon Copy Cloner for the OS X partition.
So since rEFIt is going to be hosed, so will your ability to use the EFI based program to boot into the three operating systems at boot time.
I assume you found this out and why you want to dump Windows on a external drive. However Apple's EFI doesn't recognize Linux as a boot option.
There is a rEFIt fork that will allow Linux to boot on a Mac: http://www.rodsbooks.com/ubuntu-efi/index.html
Windows as you now know can't be booted off a external drive, however if your use of it is minor, you may want to consider using a virtual machine to run it in OS X or Linux instead using the free VirtualBox.
Windows in BootCamp or Virtual Machine?
You should Carbon Copy Cloner the OS X 10.6 partition to a external GUID OS X Extended J (JHFS+) drive.
You can use WinClone 3 in OS X to clone the Windows partition to a external drive, but it's a backup only, no booting capability. Restoring it will boot on the internal drive of course.
Linux you should already know how to clone it to a external drive using dd.
I advise you use the 10.6 install disks to set up your new partition scheme, but your going to have to uninstall rEFIt and return the machine and firmware back to basic Apple factory system as possible before doing anything.
EFI doesn't get erased, it resides in NVRAM and the EFI partition, controls the at boot key commands to boot off OS X install disks, so it's important to uninstall rEFIt completely before upgrading OS X.
If the Windows version your using is XP, to install that first using BootCamp in a fresh 10.6 install and reverse clone using WinClone before upgrading to 10.7 or above. It will be grandfathered in, but can't be reinstalled later.

Can I clone an intel based iMac to a powerbook G4

I have an intel iMac (2006) running Tiger, and have just procured a powerbook G4. Is there a way to clone the iMac onto the powerbook. I do;t have much knowledge of the differences between the intel chips and powerpc chips as to whether they cause issues being synced with each other. What I am looking for, is to be able to use the laptop for travel and have the iMac at home, but the flexibility of the data synced - like email, calendars, contacts...etc.
Any help will be greatly appreciated.

It depends on precisely what you mean by "clone". If you just want to synchronize data, there are utilities such as ChronoSync that can keep your systems in sync. As long as you use the same apps, it shouldn't be a huge problem though it can be a bit tricky with some apps to figure out what needs to be synced. It's generally not recommended to try and clone the OS and applications themselves between Intel and PowerPC Macs, even if you have legal licenses to run the OS and apps on two systems, since you often don't get the correct versions onto the second system.
Hope this helps.

Can you restore Time Machine to any Intel based Mac?

I have a bet with a friend on this one.
If you have a full Time Machine backup of your Intel based Mac and your Mac breaks down, can you use your Time Machine to restore the full system to any other Intel based Mac? Or is your Time Machine backup specific to the computer model you were using?
Similarly, if you are running your Intel based Mac off of an external drive (like a portable USB drive), can you carry that drive with you and boot any other Intel based Mac off of it, so you can, for example, use the same system at work and at home?
Thanks,
doug

If you have a full Time Machine backup of your Intel based Mac and your Mac breaks down, can you use your Time Machine to restore the full system to any other Intel based Mac? Or is your Time Machine backup specific to the computer model you were using?
The backup is specific to one particular computer, not just a computer of the same model. You can use Migration Assistant on a different computer to get all your user accounts and data onto another computer if that computer already has OSX installed.
Similarly, if you are running your Intel based Mac off of an external drive (like a portable USB drive), can you carry that drive with you and boot any other Intel based Mac off of it, so you can, for example, use the same system at work and at home?
Not always. It won't work on a Mac that shipped with an OSX more recent than that on the USB drive. Also there are some OSX updates that install only on certain hardware, so you my want to run Softwae Update when you move the USB drive to a different Mac.

How can I connect a LED Cinema Display to Intel-based iMac?

My iMac24" (Intel-based 2.8 Ghz Core 2 Duo) has a Mini DVI Output. The LED 24"Cinema Display has a Mini Display Port. Is there an adapter available to use the Cinema Display as an Extended Desktop?
Need help urgently! Thanks.

no 3rd party solutions available?
As I said, there are no converters available, from any source.

Error "You can't open... ...on an Intel-based Mac."

Hi.
On the System Preferences app. When I try to open Mail, Contacts & Calendars (preference pane), it gives me the following error:
"Preferences Error
You can’t open Mail, Contacts & Calendars preferences because it doesn’t work on an Intel-based Mac."
I already re-installed OSX Mountain Lion, and it didn't fix anything.
I noticed however, that the actual preferences file: InternetAccounts.prefPane has different permissions than the rest of the .prefPane files.
- All other .prefPane files have "System" as the first user, however, my InternetAccounts.prefPane file has "Me" (myself) as the main user, and not the System user.
Question:
A. Does someone have a solution for the problem in general?
B. Can someone check their InternetAccounts.prefPane file and let me know the preferences. The file is located at: System/Library/PreferencePanes/InternetAccounts.prefPane
C. If, your InternetAccounts.prefPane file has System as the first, or any user, can someone let me know how to set System as a user? Hopefull this will fix the problem.
Thanks to anyone trying.

Ok did some research - here is another thread which seems to address your problem.

How can I check for spyware on my Intel based mid-2007 iMac running Lion?

I recently received a message stating that my Intel based iMac desktop may contain spyware plus a friend sent me a copy of an email to my iCloud email address that i did not send to him, i was not even home using my iMac on that date. I do have anti-virus software on my iMac from Integra and I do a scan each day before i shutdown the iMac and have not received any such warnings from that software.
I do appreciate any and all advise I can receive in this matter. A long time ago I did receive an email a Yahoo based email address and was notified that I could possibly loose my email account due to junk email being sent from my iMac. I did have the support/warranty from Apple at that time and a phone rep did talk me through steps to check for any intrusion to my iMac with negative results, the iMac was clear of any spyware, etc.
Hoping there is the same for this issue.

You can't use a specific Mac OS X disc for a Mac with a different computer. First, call Apple and buy Mac OS X Snow Leopard > http://support.apple.com/kb/HE57 Then, make a backup, insert the DVD and upgrade OS X. Finally, open  > Software Update and install the most recent version

How can I tell if my iMac is Intel based?

How can I tell if my iMac is intel based?

To get more information about your computer, go to the Apple in the upper left corner of any window, then "About This Mac", then "More Info..." Copy and paste the information here, but omit the serial number and Hardware UUID (if present).
Mine is not:

Switched on my imac 24inch intel based and all I get on screen is a folder with question mark flashing,I had backup on external hard drive but when I try to reinstall it can not find my mac hard drive

Hi when I started my intel based imac this morning all I am getting is a folder with question mark in the middle flashing,I have external hard drive with backup,but when run disc utilities it does not show my mac hard drive.hope someone can help.(it's running mountain lion, well it was)

Try starting up your Mac while holding down the Option key. That should prompt the Startup Manager window where you can select the startup disk then click Restart.
The question mark folder indicates your Mac cannot find a system folder to boot from.
A flashing question mark appears when you start your Mac

You can't open Mail, Contacts & Calendars preferences because it doesn't work on an Intel-based Mac.

I updated my Mac to Mavericks and after that, I can't open the Mail, Contacts and Calendar preferences.
Every time I try, I get the following message:
"You can’t open Mail, Contacts & Calendars preferences because it doesn’t work on an Intel-based Mac."
I tried this workaround from the Mountain Lion thread (https://discussions.apple.com/message/21303574#21303574) but it didn't worked.
Further I deleted all files in the Library Preferences folder, but it didn't helped also.
Can anyone help me please?

Hi Michael,
I had the same problem. And I found a fix.
I noticed that on a different system running Mavericks without any problems, the preference pane isn't called 'Mail, Contacts & Calendars' anymore, it's now called 'Internet accounts'. The fact that it's still called by the old name on your system, means it somehow wasn't replaced while updating to Mavericks.
So the cure is pretty easy:
On a different Mavericks system, go to /System/Library/PreferencePanes/ and copy the file InternetAccounts.prefPane. Take it to the system you're trying to fix, and paste the prefPane file in the same directory. Reboot, and it should all work fine. At least it did in my case.
Cheers

You can't open Dictation & Speech preferences because it doesn't work on an Intel-based Mac.

I cannot open or use Dictation & Speech in System Preferences. When I try to open it I get the error:
"You can’t open Dictation & Speech preferences because it doesn’t work on an Intel-based Mac."
I have tried repairing the disk from the installation CD and repairing the permissions and I have also tried re-installing Mountain Lion but the feature still does not work. Any ideas?

Open Finder, press Option key and select Go > Library. Open Preferences and delete com.apple.systempreferences.plist. If you can't open, do a backup, format and install

I have Final Cut Studio V1 - the PPC/Intel V5/5.1 cross-grade version, which would suit your requirements perfectly. (I have it for sale at present down here).
If you keep looking, you're sure to find a similar second hand copy in your area, without the need to upgrade your graphics card.
I'd go for Final Cut Pro as above over any version of Express. FCP has the full version of LiveType - not the truncated version that was released later on.
