I have a macbook and a imac both running snow leopard I can screen share from the macbook to the imac but the imac will not screen share with the mackbook.

I'm on 10.7.3 at the momrnt, but I suspect these files...

Safe Boot, (holding Shift key down at bootup), run Disk Utility in Applications>Utilities, then highlight your drive, click on Repair Permissions, reboot when it completes.

(Safe boot may stay on the gray radian for a long time, let it go, it's trying to repair the Hard Drive.)

Trash these files but d not empty the trash yet in case we need to put them back...

/Users/YourUserName/Library/Preferences/com.apple.systempreferences.plist

/private/var/db/launchd.db/com.apple.launchd/overrides.plist

/Library/Preferences/com.apple.RemoteManagement.plist

/Library/Preferences/com.apple.RemoteManagement.plist.lockfile

Reboot & set up Screen Sharing again.

can you ping the imac using the macbook and vice versa?

you can do ping via network utility or terminal.

Yes I can ping both.

connectivity is fine then.

there is one option i can suggest but i cannot guarantee if this will work for you. this is what i have on my system. i created a sharing only account.

this is how it looks.

then try connect via finder. you should see the other computer on the sidebar of the finder window and click on share screen.

Yes, I was thing those files on the iMac needed redoing.

can you also post logs on both when you try to connect. do this on both computers.

open console, click on all message then Clear display. should look like this.

then try to initiate the screen sharing and let's see what will the logs say. post the logs generated from both computers.

Have we checked the iMac's System Preferences>Security>Firewall to see if Screen Sharing is enabled allowed, or try allow all incoming connections?

Oh yeah, nobody wants MacKeeper, thanks for the report! 🙂
