Hi MacFriends
I have an IPAD "1" which connects to youtube perfectly,
Recently bought a MacBook - it cannot connect to youtube (other videos / websites etc no problem)
Does anyone have any idea why ? :confused:

A MacBook has nothing to do with iOS5 (the section you've posted the thread in).

Also, you're too vague. What does it mean "it cannot connect to youtube"?
Do you mean the website fails to load, or that you just can't see videos?
If that's the case, you might have to update (or install) Adobe Flash player.

Thanks Lost soul

Sorry it was too vague.
I cannot download the youtube site at all.
I have:
* flash 11.1.102.55 installed.
* vpn operational

i don't think all youtube videos have switched to HTTP Dynamic Streaming yet, so RTMP might not be allowed through your VPN. Does it would without a VPN connection?

Google "YouTube 5 Version 2" as an alternative method for watching youtube videos in a HTML5 browser, works smoothly.

Hi Slenpree

I have vpn and my iPad goes into youtube perfectly but the macbook cannot get into the youtube site.
I googled in as you said, and its a www.youtube... site, I cannot open the page / get into the site at all.

sounds like a DNS issue. I assume you are putting .com on the end. Applications -> Utilities -> Network Utility. In the "Ping" tab, enter 74.125.230.130 and press ping. Do you get a response?

Yes Slenpree: got a response ok
--- 74.125.230.130 ping statistics ---
10 packets transmitted, 9 packets received, 10.0% packet loss
round-trip min/avg/max/stddev = 570.311/605.932/668.186/33.399 ms

now use the "lookup" tab with youtube.com. It should respond with numbers where the first 3 octets are the same as one you did a ping on.

If not, you need to change your DNS server.

The 10% packet loss might also be an issue.

Hi Slenpree

Thanks again for your help / interest.
I am not familiar with pinging and dns , so have been googling since your last post.
1) Background : both iPad and macbook are using same wifi and vpn system.
* iPad can get onto youtube, macbook cannot.
2) I understand :
* when u type in a web address, the computer 1st looks into its internal cache to come up with the DNS required to open the site / download
* If it cannot find it , it goes the the ISP to find it.
3) It seems the solution is the the internal came of the iPad has correct DNS and internal cache of the macbook doesn't .
* If this is the case how do I get in to check computers .ipads internal ache ? OR
* am I looking at this simplistically and going down wrong track ?
