Odds are there are no apple servers or mirror servers close to dubai... thus no way to feasibly attain updates... I dont know what else you can do other than go into the "local" apple store to update your computer.
What ISP are you using? I know several asian ISP's are forced to filter content. I can't imagine they would be killing apple update packets but who knows.
I have a Macbook Core2Duo running version 10.5.8. I have 2 problems which I am not sure if they are related:
1) when trying to do a 'Software Update' it just keeps trying to search forever saying 'checking for new software'
2) I have just been to relocated to Dubai. I keep trying to download news.bbc.co.uk and it goes on for a very long time if not forever. However, it will download bbc.co.uk. Same problem with cnn.com
I would be grateful for your help.
Oh and by the way Happy New Year
