why it is so slow to download El Capitan?

Thanks. Worked like charm.

But could explain how it happened 😝

Am I the only one this didn't work for?? I'm trying to download El Capitan on a 2011 Macbook Pro. I'm running OS X 10.6.8. First of all, I don't see an estimated time for download. Second of all, I've barely seen an improvement on the progress bar after repeating what everyone else did. Any suggestions??

What he said ... I have same year mb pro doing painfully slow download. came on here to see what was up ... guess I'll wait until I try that dns...

I tried several of the tips here, but none worked. Then I quit my anti-virus program, and BAM! Went from 8 days to only 19 minutes. By the way, turning OFF the anti-virus did not work. I had to QUIT the program.

Now uninstall the anti-virus and depend on what OS X gives you are you are all set.

I am having slow very slow download speed for El Capitan. I am with TPG I have changed to different DNS addresses but no gain. I do not have any antivirus installed. My firewall is disabled. I do not have any network firewall just a standard modem/router from billion. I have been downloading for the last 6 hours and I have only downloaded just over 2GB of total 6.X GB. Any of you gentleman many suggest anything ?

Entering that DNS in settings immediately breaks my connection. Safari stops working, nothing will download.

Too bad. I have a remaining time of 3 DAYS until download completion! 😠

The suggested DNS didn't work but then I used DNS 203.122.233.11 and it worked a treat.

First paused download, deleted all the current DNS, then added 203.122.233.11 and hey presto 3 days to 1 hour!

Found the DNS here http://www.theshell.guru/fix-slow-os-x-el-capitan-download-speed/

I heard a theory as to why changing the DNS server is working.

Apple uses Akamai edge servers to distribute the downloads around the world. However, some ISPs have a hodgepodge of IP addresses where some look like they are in a different region. This may cause the download to be sent to an Akamai server that is not close to the user.

Changing the DNS server may cause a different Apple server to be contacted which is closer or at least has a faster path do your door.

AM on install window, I can't go to network prefencess cside old version of OX is gone.

its so slow ( 86 hours)

anyone , help ?

There are slow servers and there are faster servers. The DNS name resolution gets to choose the regional server.

If the DNS name resolution things you are closer than you are, you may get a server very far away (there is more than one ISP that has blocks of IP addresses which used to be located on the other side of the globe; if the DNS server has not learned its new home, then it may assign a server on the otherside of the globe, maybe going through some restrictive governments country boarder firewall).

In many cases the home router is the first level DNS server and forwards requests it does not have cashed to the ISP's DNS server. HOWEVER, most home routers all you to specify a specific DNS server, and not take the one from the ISP. You could plug in the OpenDNS servers or Google DNS servers and see if that helps. BUT IT WILL NOT HELP an existing transfer. That is in progress and the server is locked in. You would have to start over again.

OpenDNS.org

208.67.222.222

208.67.220.220

Google DNS

8.8.8.8

8.8.4.4

Well I tried the DNS thing and it stopped me from accessing the internet at all!

I had an error message telling me it was the incorrect DNS and did I want to revert to the original one, which of course I did, internet working now but still slooooow El Cap download :(

do you have to delete the one that is already there, or just add another one

If you have your own custom DNS setting, then just drag the desired DNS address to the top of the list.

System Preferences -> Network -> Advanced -> DNS

Did you download it already? Because I have the same problem too 😟
