Resetting MacBook

Hi, I bought a new MacBook and I'm looking for some advice on the following:

01 - I need to move all of my existing files over from my old MacBook to my new MacBook, and then re-install my applications... what is the best approach for this:

A - manually migrate the files via external hard drive and manually re-install each app

B - clone / image my old MacBook to my new MacBook (even though there is 3 years between the models)


02 - I want to give my old MacBook to a friend, so I want to wipe it clean before I do... what's the best method?


Thanks in advance for your help.

The Mac will do this automatically for you. When you first start the new Mac, make sure the old Mac is handy. The new Mac will ask you if you want to migrate apps, settings and files from another source. Say yes, connect the two Macs by ethernet and everything will be done automatically.

Once that is done, to wipe the old Mac, open the users and groups preference pane and create a new administrative user called "Temp".

Log out of your existing sure and log back in as Temp.

Open the Users and Groups prefs pane and click on the lock at the bottom left to unlock the pane. Then highlight the old user name and click the minus sign to delete it. Choose the option to delete the user folder.

Once that is done, open Disk Utility (found in /applications/utillities) and click on erase, then on Erase Freespace.

Cool, thanks...

Just a few more questions :-)

01 - the MacBook Air doesn't have an Ethernet connection, what other options do they give you?

02 - from a performance point of view, would I be better off manually installing files and apps, instead of copying a setup that is 3 years old now? (maybe I'm still stuck and thinking my old Windows days)

You can do it wirelessly, but it would be slow. Better to buy a Thunderbolt to Ethernet Adapter (http://store.apple.com/us/product/MD463LL/A/thunderbolt-to-gigabit-ethernet-adapter) so you can connect the Air to ethernet.

You are better off letting the Mac do the migration. It will disable any non-compatilble software automatically.

The Mac migration is amazing. Once it is done, your Mac will reboot and you will have all your old preferences, bookmarks, passwords, wallpaper, screen savers and settings. No need to set up anything new.

If you have a large User profile of several hundred Gigabytes and want less down time, you can save some time by using the rsync command line tool to just copy the /Users/ folder while you're still using the system.  You then do one final rsync with another Admin user account.  That way, when you run the Migration Assistant, you only have to copy the smaller System and Network settings along with the /Applications, speeding up the time you do the Migration.

I have several users with several hundred Gigabytes of Data in their profiles, and doing the rsync reduces the amount of time they are without their computers.

That's fine in a corporate setting, but for a home user, it is much simpler just to start migration assistant in the evening  and let it run overnight.

It works for a home setting too, if you don't have as much time.  Sure, Migration Assistant is easier, but it means your system is out of commission for much longer.

I must admit that I don't much care if my system is out of commission overnight. I tend to be sleeping then.  :-)
