Someone is logged in but I have no password.

It has an L2 Cache 512kb

Memory 512 Mb built in and one slot empty.

I don't know anyone with knowledge of older apple sys.

I agree with BDAqua that old Mac is not likely to work on the modern internet.


I'd advise you to reconsider gifting this old tech to your friend who is "not too computer literate". You won't be doing her any favors giving a computer that is outdated and obsolete and with high potential for hardware failure.


If you are intent on providing a low cost computer for your friend, consider buying a quality used Mac from a known good provider of Mac hardware and accessories such as OWC/macsales. This link will get you to their new and used Macs website: New, Used and refurbished Macs – macsales.com

(I'm unaffiliated, just a satisfied customer.)


Look for a Mac that is not more than 5-6 years old. This could provide another 5-6 years of productive use for your friend. You might also consider a used iPad if your friend only needs the basics for email and similar tasks.

See if you can create a new administrator account by restarting the Setup Assistant:

  1. Boot into Single User Mode: Start/restart your Mac. As soon as you hear the startup tone, press and hold ⌘ + S until you see a black screen with white lettering. (If you end up back on the login screen after a flash of the black screen with white lettering, enter your password and it will return to the black screen.)
  2. Check and repair the drive by typing /sbin/fsck -fy then ↩ enter - as directed by the on-screen text.
  3. Mount the drive as read-write by typing /sbin/mount -uw / then ↩ enter.
  4. Remove the Apple Setup Done file by typing rm /var/db/.AppleSetupDone then ↩ enter.
  5. Reboot by typing reboot then ↩ enter.
  6. Complete the setup process, creating a new admin account.


Be very careful to notice the spaces in those Terminal Commands.


Once you've done that the computer reboots and it's like the first time you used the machine, except all your data will still be there. Your old accounts are all safe. From there you just change all other account passwords in the account preferences!!


I understand & remember quite well the 1st time I did it, but there's not another way as far as I know. :)


Paste these lines into Text Edit so you can arrow thru & see the spaces...


/sbin/fsck -fy

/sbin/mount -uw /

rm /var/db/.AppleSetupDone
