Newer iMac with better processor, but lower GHz?

I am thinking of buying an iMac. The new iMacs have i5 and i7 processors, both between 2.7 and 2.8 GHz. I have done a little research on youtube and wikipedia and i found out that the older imac (with an i3), had way more GHz (over 3.1). Why does the newer one have a newer/better processor but a lower/slower GHz?
Could somebody explain that to me?
Thanks in advance.

Clock cycles for processes have become less advantageous than processing over multiple cores since Apple started using G4s. When it switched to Intel processors, it focussed more and more on cores, as it had to maintain the processor temperature cool enough for notebooks, while speed gaining speed through other means. Very few programs these days are completely processor dependent. Many are GPU dependent, RAM dependent, hard drive speed dependent, and disk space dependent. If upgrading to a newer machine means compatibility with software that you don't already have, but need, or software that is able to take advantage of a newer machine better, then by all means get it. Otherwise all you might be buying into is longer life of a machine under warranty once AppleCare is bought. And don't forget, no Mac can run an older Mac OS X than shipped with it.

I recently purchased a new iMac with an external drive. I want to transfer my files from my old iMac to the external drive, but I'm afraid that doing that will compromise the use of the external drive on my new iMac. Comments? Help?

I recently purchased a new iMac with an 1 Terrabyte external drive. I want to transfer my files from my old iMac to the external drive, but I'm afraid that doing that will compromise the use of the external drive on my new iMac. I have not downloaded the external drive's software onto my old Mac because of this concern. May I simply "drag and drop" the contents I want transferred to the external drive, then set up my new Mac with the drive and download there? or is there a better procedure? Comments? Help?

If your intention is to copy a just documents and data (word processing files and music for example) then yes, you can use drag and drop. If you want to transfer data and applications and permissions, it would actually be easiest to connect the drive to your old computer and turn on TimeMachine. Once TM is finished, connect the drive to your new computer and restart it holding the option key to get into Recovery mode. Then you can use the restore from TM option to transfer your data and programs to the new computer.

I purchased a new iMac with latest iLife suite, however, IMovie will not read my videos. I deleted a 3iVX file that was not working but nothing happens now. Help

I just purchased a new iMac with the latest iLife suite. As part of the migration process in setting up the new machine the 3Ivx video codec was brought onto the new machine as well as my old movies. When I tried opening the movies iMovie crashed and told me it had a problem with the 3IVX video codec, in doing some research I found that the 3IVX video codec created a problem so I deleted it and downloaded Perian 123. The Perian 123 works well with Quicktime but iMove does not now see my old movies. At this point I cannot open any of my movies. Can anyone help? Thanks

There also might be a more updated, compatible 3ivx codec you can install, or just try re-installing a newly downloaded version of of the same old codec: http://www.3ivx.com/download/macos.html
Otherwise download and install MPEG Streamclip: http://www.squared5.com/svideo/mpeg-streamclip-mac.html
In iMovie hold down CTRL and click on the clips that don't open. Choose Reveal in Finder. Convert those files by dragging them into the window of converter program, and save as Apple Intermediate Codec (AIC). That format is native to iMovie and will work perfectly.

I am using Photoshop CS5 on a new iMac with a wireless keyboard. I used to be able to hit F11 to perform a custom sharpening action but now the F11 key is the volume control key and I have tried everything to disable or switch the volume key. I have also tried assigning other function keys to initiate the action. Is there a simple solution to this? What am I missing?

Try unmounting the volume on your iMac using Disk Utility. Then mount it again. You may need to reboot the laptop or relaunch its Finder process (using the Force Quit window) after remounting the drive on your iMac. Remember that no process may be accessing any files on the drive you plan to unmount, or the unmount will fail. Unmounting and remounting an external drive on my iMac made it become visible on my MacBook Pro after it had disappeared.

I reinstalled tiger on one iMac, but want to re-upgragde it to Lion. I don't have the discs anymore, but I installed Lion from the Mac App Store. Now that I'm back to 10.4, I don't have the App Store. I have a new iMac with Mavericks, but it won't let

I have a 2006 iMac that I've upgraded to each new os as they came out. I just wiped it (for the kids to use, I have a new iMac with Mavericks) and reintalled Tiger from the original discs. I want to get it back to Lion - which I purchased from the Mac App Store. But Tiger doesn't have the App Store and I don't have the discs anymore from the intermediate versions. I tried downloading Lion from the new iMac but it's not available...
Any ideas?

To get to the App Store, you need to upgrade the Tiger machine to Snow Leopard.

How do you upgrade OS X 10.4.11 tiger to a higher version of operating system such as OS x 10.5.6 as have tried running the upgrade disc on imac 5,1 with intel processor but only get message saying this cannot be installed with no further explanation ?

Retail Leopard disc looks like this;
(The disc itself has the same logo). If the one you've got is grey it simply won't work.
Given the retail and second hand prices of Leopard (usually some on Amazon MP), you'll probably find it cheaper to go directly to Snow Leopard, although there could be software updates and printer driver problems that could nullify the difference.

I have purchased a new iMac, with Safari 5.0.5, but it won't retain bookmarks, I thought I can download a new Safari from Apple. So I deleted Safari from the application folder.

I have purchased a new iMac, with Safari 5.0.5, but it won't retain bookmarks, I thought I can download a new Safari from Apple. So I deleted Safari from the application folder.
Then I tried to download Safari from Firefox but after finish download, what I got was a dmg file, with a pkg icon (an opened box) and it can't be installed. Same with Google Chrome.
My question is: how can I download Safari? And will it retain bookmarks?

Reinstall Safari from the Optional Installs.pkg on your Mac install disc that came with your iMac. Or in your case, you use Pacifist to extract the Safari app from the .dmg file.

Without knowing what you have tried please open System Preferences - Sharing - File Sharing and select File Sharing. If you still have trouble you can call AppleCare in the morning when they re-open. You have 90 days of telephone support if you haven't already bought AppleCare.

It is strange. I thought 10.x might be the more recent but it also locked up when I tried to the web export. I ran into the no autoplay issue with the webpage so I'll need to look elsewhere to replace a Flash gallery... oh well. Looks like there are probably JS option that might work.
Thanks.

Trying to weigh ALL costs involved.
Thanks for any advice!!!

Anything you have that is powerpc code only will not run on a new machine. OS X 10.8 has no support for powerpc code (universal binary programs should be fine).
Other than that warning, without knowing exactly what programs you have, and what version you are on, it is hard to say whay will or will not migrate alright.
you might need to do some web searching and check apps at sites like roaringapps or on the programs Company web site.

I have a new Imac with OS Lion. When i use the apple migration tool to transfer from my PC to the Mac, it runs for two hours or so exchanging my pictures and address book, but when completed, I cannot locate anything on the Mac! Any suggestions?

You have posted to the older PPC iMac forum. You need to poster to a newer iMac forum.
