Q: iMa  Mac. HD    MY QUESTION:   LOST EVERYTHING ON COMPUTER.  HAVE USED DISK 1 AND 2 AND REINSTALLED.  IMAIL AND ICHAT WILL NOT SEND.

Ok, is gMail POP also?

Gmail send but not receive...

Here are two steps that have come in handy in related situations

1) login to gmail on your computer or device via a web browser

2) once logged in successfully, go to this URL to unlock:

https://www.google.com/accounts/DisplayUnlockCaptch

One step at a time!

Ah, so gMail works OK both ways then? I guess I misunderstood.

Did you try changing the port to 110 & authentication to SSL Off on the other one?

Great news, thanks!

Is iChat working or not yet?

Ah, yes, 10.5 has been left behind for most of iCloud, but you can get a free AOL/AIM account that will work...

OS X: Using me.com or mac.com IDs with AIM in iChat requires OS X v10.7.2 or later - Apple Support

I have no need for an AOL account, other than to make iChat connections in older OSX versions.
