Restored my computer, now im stuck!!! Please help!!!

Your Mac is old enough that it should have been prebundled with a set of original disks. Call AppleCare

to get them. Going to 10.7 is only necessary if the application you have is not compatible with your current operating system, but definitely is for 10.7. See http://www.roaringapps.com to figure that out.

The original discs include some version of 10.6, which supports even more applications, because as of 10.7 or later Rosetta is gone:

If you still desire to get 10.7, setup your App Store account and link it to your computer

And request them to set you up with a redownload for the computer.

Remember 10.8 is the same cost as 10.7, and 10.9 is free.

Without knowing if you are dependent on a specific software library, it is hard to know what options to give you.

1. Is your machine able to get to a place you can manage the files?

2. Do you have any specific tasks you want to do with your Mac?

3. Have you made any backups?

4. Is there any data on your machine you want to recover before doing any further steps?

5. Do you have anything external to the computer other than a mouse, a keyboard, and some means to get online?

6. What is the means you have of getting online? Do you have a cable, satellite, DSL, FiOS, or dialup modem? Is it integrated with WiFi or not?

Not really, unless you want to pay. I suggest bringing the machine into the Genius bar, or an Apple Usergroup if you want instant feedback. They will give you an occasional free bit of advice. There may also be people at the Apple Store who can help you with their in store machines so you can see what can be done. What country are you from?

> I followed some instruction on some forum where it said that I had to delete "Machintosh HD" disk or whatever so I did and now im stuck!!

That's your problem. Doing stuff that crazy that makes absolutely no sense.

Macintosh is the computer. HD is the hard drive. Delete means erase, get rid of, etc...

Honestly, it sounds like you need one of the "For Dummies" books. Don't be afraid of them.

Now when you sell a machine, it is likely a good idea to get the original installer discs. That's why I recommend calling AppleCare for them. They are only about $20. That will get you a base system, but anything you had on there before would be lost. That's why I ask those questions of you. If you don't have anything critical, that's what I'd do first is get the original discs. Once they have the original discs, and you can verify the computer is empty, that's pretty much all you need.

Get those discs, and someone here can help you set it up.
