    This could be an easy fix, cause I think I might have a solution I thought of on the way to work.

    So what happened was, while backing my old macbook to Time Machine, I switched the wifi off so I could go online a lot smoother with my new Macbook Pro. I think it also sped the backup process up too, cause I've never seen it back up 10 gb's that fast.

    Anyway, I migrated it to my new Macbook Pro with the external HD. It brought over all my user accounts, and when I logged into the one I was on on my old mac, the wifi was still toggled off.

    So i tried toggling it on, the signal indicator was full bars. Then it switched off. I tried doing this a couple times to no avail. It was weird, cause the internet was JUST working right before the migration.

    Do you think I can go back to my old macbook, toggle it on, time machine back it up, then migrate it and it should work? or anyone know what else I can try?

    Maybe have a look at this thread on the Apple support forum:

    From the 2nd post, it seems the OP had no luck with booting in safe mode, but ultimately solved it by removing the 2 files mentioned in the thread.

    Back up those 2 files first, then delete them and reboot.

    I remember when I was jailbreaking my iphone some years back I had the ability to do the whole file add/removal in terminal I think it was.

    I just haven't really messed around with the technical stuff in a while.

    No need to mess with terminal to remove those files.

    In finder, open the "Go" menu, then click on "Computer". In the resulting finder window, open "Macintosh HD" (or whatever your boot drive is called), then "Library", then "Preferences", then "SystemConfiguration".

    Inside that folder, you'll find the 2 files:

    NetworkInterfaces.plist
    preferences.plist

    Make a backup of these 2 files, then delete them from the original location, empty the trash, and reboot.

    That seems to be what fixed it for the person in that thread.

    No problem......let us know how it works out for you.

    When I say backup, I mean make a copy of the files before you delete them just in case you need to copy them back to their original location at any point. Once everything is working, you can delete the copies.

    Copy them to a USB key if you have one.
