OP:
Do you have an external USB drive available?
If so, fastest, easiest, surest way:
1. Use CarbonCopyCloner to create a cloned backup of the OLD internal drive
(CCC is FREE to download and FREE to use for 30 days)
2. Take NEW MacBook out of the box, don't power it on yet
3. Connect cloned backup to the new MacBook
4. Press the power-on key and begin setup
5. At the appropriate moment, setup assistant will ask if you wish to migrate data from an older computer or drive -- you DO want to do this, so...
6. ..."aim" setup assistant at the external cloned backup
7. NOW -- you will be offered choices as to what to bring over (apps, accounts, data, settings)
8. If you DON'T want to migrate apps, I'd choose everything else and the click ok
9. Let setup assistant do its thing
10. When done, you'll be presented with a desktop that looks like your old one did.
If you didn't migrate 3rd party apps, you'll have to reinstall them.
IF you kept pictures, docs and videos in your [old] home folder, these will all be brought over.
IMPORTANT:
If you've already booted up the new MacBook and set up a NEW account, the above isn't going to work as expected.
You'll probably end up with TWO user accounts.
Could result in a permissions nightmare!
