Lost admin permissions after migrating from imac to mbpro
Hello, I bought yesterday a new mac book pro.
As I wanted my previous settings I used migrating assistant via airport but that was very slow on my 802.11g wifi network.
So I stopped it, created a new account (let's call it "A" for easier communication), and I transferred my imac's old account ("B") to my macbookpro through firewire.
After that, I logged in with "B" account and I deleted the "A" account (when password was needed i typed "A" acc & pass).
Without having noticed it, "B" which I only now have has standard permissions and I don't have now any admin accounts on my mbp.
Is there any quick way to make "B" acc admin (system now recognises no admin accounts on his memory) and not of course any kind of format?
Thank you in advance!
