How To Transfer Your Data From Your Old Mac to Your New Mac

In: Applications| How-To

3 Sep 2007

I just got my new Intel 24 inch iMac. This iMac will replace my older one. If you spend a lot of time working on your Mac then you understand the necessity when you upgrade to be able to transfer your data from one machine to the other in a seamless fashion. I did not want to spend much time on data transfer and application installation but I wanted to import my data and settings to the new Mac as quickly as possible so the next day I could be operational. I am going to show you how to go about data migration on Mac OS X.

1. Mac OS X comes with a built-in application for data migration called Migration Assistant. This incredible application can painlessly transfer files from one MacIntosh to other. The first thing you need to do is launch “Migration Assistant” located in /Applications/Utilities.

2. Once you double click on the Migration Assistant’s icon, the application will launch and show you an introduction window. Click Continue. A window might pop up asking you to type your administrator password.

3. The next screen will allow you to choose a Migration Method. You can either migrate files from another hard disk connected to your computer or from another Mac which is the option that we are going to chose. Then click Continue

4. Now the assistant will prompt you to connect the two Macs together using a Firewire cable.

5. Then you will be prompted to restart your older Mac computer in Target Mode.

6. After you restart your older Mac in Target Mode, Migration Assistant will look for connected drives. Once it finds the hard drive(s) containing Mac OS X, it will ask you to select the System to migrate from. Select the appropriate drive and click Continue

7. The application is now ready to Migrate your data. In steps 1 through 4, the Migration Assistant will let you configure the Migration process by selecting which user account(s) to migrate, whether you want to migrate the network settings, sharing settings, Applications, Files and Folders etc.

8. Your data migration will now start. The duration of the transfer depends on the total size of the files to migrate. It can varies between just a few minutes to a few hours. In my case I migrated over 450 GB of data and it took about 4 hours. You can now leave, hangout with friends, have fun, drink a beer, until you see the following screen:

You are now all set. You can turn off your old Mac and login to your migrated account in your new computer. You will be amazed how great of a job Migration Assistant will do for you. You won’t even need to re-install all the programs that you had on the old machine as this assistance can migrate them for you. Migration has never been so easy and painless.
Feel free to post some comments should you have any questions.

I just bought the new Imac, the alluminum one. I have an old G5 Imac pre intel. I’m wondering how migrations assistant will handle things such as programs that use classic and programs that might not have the update to intel? I realize that I won’t be able to use my classic on there but I wonder if Migration assistant will recognize that and maybe freeze or something. I suppose if it transfers everything I’ll have to delete them later on. Thanks for your info though It eases my mind considerably about my new Imac.

I believe that Migration Assistant could also copy your classic System Folders to your new Mac. If it does so then you classic programs might still be able to work under classic.

What I do know for sure is that any non intel program will run seamlessly on your new Mac through Rosetta. Depending on how much resource consuming your old programs are, they might be slightly slower on the new intel platform if they run through Rosetta.

Your best bet would be as much as possible to get an intel or universal binary version of your applications where and when possible to have them run natively on the new intel-based Mac

I hope this helps.

I have spent the last couple of hours trying to use migration assistant to transfer from my old G4 to my new iMac 20″ Duo Core intel machine. It doesn’t work. It won’t recongnize the drives of my old machine when it has been started in firewire transfer mode.

I spent some time with the apple support folks and found out that it is an intel vs. powermac thing.

If you have any ideas on this it would be great. Thanks.

Ryan,

If your old G5 does not turn on then try to start it up on Target Mode.

You can achieve this by pressing the power button,
then as soon as you hear the shime sound you press the “T” key on your G5’s keyboard and maintain it pressed until you see the firewire logo sign on your screen.
At this point you can release the “T” key and plugin your G5 to your new iMac using a Firewire cable.
You will now see your G5’s drive onto your iMac and you should be able to run the migration assistant from your new Mac specifying the G5’s hard drive…

I hope this helps… Good luck.

Wow…I’m getting the SAME issue “can’t find OS X” drive…and of COURSE there’s OS X drive on my G4. Good grief…just spent $2k and can’t move my files over? I was told it was almost “automatic”…well, 3 hours later I’m NO closer and the Apple Care I purchased got me nowhere either.

PLEASE…does anyone have any ideas????

I’m using the 800/400 firewire cable and my older Mac does boot into the “transfer” mode with the firewire icon on the screen. New mac does nothing.

What OS is your old G4 running? You may want to consider upgrading it first to leopard and then trying it again. Not sure why it does not show up.

Transferred music and photos from 2005 power mac to daughter’s new ibook using migration with same network connection. Seemed to work fine. She wants the photos to go into her new iphoto and music to go into her new itunes. But neither photos or music seem to be there. How do we access the files on the new ibook?

I’m trying to transfer from an old G3 iMac running Panther to a new G5 iMac running Leopard. I got as far as the Disk Target Mode on the old one (which shows the globe) but it won’t switch to the FireWire mode. I read in Apple Help that if you had OS 9, you have to get FireWire 2.3 software. I’m still up in the air on this too. Please help! Thanks.

Hi! Can I choose which applications I transfer from my IMac to my Macbook Pro? Or do I by selecting transfer initiate a complete transfer of all programs other than those already present on my new macbook? I do not want all of the applications loaded on my older computer. Thanks. Tim.

Trying to move an application from an old mac to a new one. Son spilled milk in old one, which is why I had to get a new one. The milk caused the firewire port to be inop. Is there a non-firewire way that anyone knows to transfer applications from one mac to another, perhaps via USB?

I have a new 21.5″ iMac and an older MacMini but have been unable to find a firewire cable locally. Is there a way to use USB2 cable or even Ethernet?
Please advise.
Thanks, Wolf

I have just transferred all files and apps from G4 to Imac using the migration process listed above. The firewire needed a new adapter that I purchased at Mac Authority in Nashville. (6 pin to a 9 pin) The Imac works great. After the transfer the G4 no longer starts. Yet it will start in Target mode. How do I get the G4 to start up?

I’ve previously done this process from an EMac to a MacBook about 4 yrs ago. I’ve forgotten a few things about the process. Does anyone know if you transfer the old programs does it overwrite any of the new ones in the new computer? I dont want to mess up the new system I am buying. I have a MAcBook and just bought a new MacBook Pro.

Thanks!

Earlier this evening (last now) a completed migration message appeared in my 2008-09 macbook 13 (source) and my 2009 imac (destination computer).

All in all a good 24 hrs passed from start to finish. Part of the reason I suspect (time) is that I mistakenly ‘allowed’ the mackbook to go to sleep..it dawned on me over night/I made the adjustment..it took 12 or so hours to finish.

As I remember there were about 65-70 GB of program applications, plus/inculding the iphoto file, mail, and browsing historybookmarks & browsing history…the latter migrated/programs not:

None of the program applications seem to have migrated (eg. the Adobe Suite, Iwork, MS Office 2008, Final Cut, etc.

I used my wireless network as the method of migration since my macbook doesn’t have a firewire port–just a couple of usb2 and an ethernet port.

The Imac HD reads 595 GB capacity and 514 GB available. The Macbook HD @ 232 GB capacity & 135 GB available.

Any help/direction will be greatly appreciated.

I was able to transfer successfully from my Ibook G4 to Macbook Pro but it is in two separate accounts and won’t let me use files from the old, imported User in the new user. I’ve tried eliminating the password in the old User. Is there any way of importing files from the other User on the same computer?
