Help needed, how to regain admin rights

[frangio]

Sorry if it's a noob question: I've upgrade my OSx86 system to 10.5.7 with iAtkos release (install/upgrade). All went smooth, but now I'm stuck with an ordinary account with no admin rights and no way to install news apps, etc.

 

When I try to change my status in SysPref, of course I'm asked admin's name and PW. Fact is, I know for sure the PW, but it looks like any name won't do.

 

IMHO there are two chances:

1 - I forgot the admin name I used fist during installation (likely... )

2 - something changed without me knowing during upgrade. As suggested, at the end of 10.5.7 upgrade I resetted the PW before rebooting, but in the procedure there was nothing whatsoever regarding admin's name.

 

Is there a way out this hassle? Or a way to know which is the admin's name saved in the system?

 

Thanks for any of you who takes the time to give me a helping hand.
