I have a late 2009 IMAC which is running 10.6.3. I am trying to upgrade to 10.6.6 to get the app store, but when I download from the download site, the download speed slows down to a crawl (2 kb/sec). The time remaining increases to multiple days, then the download fails. I have been searching various forums and tried lots of things - - connected via ethernet instead of airport. This allowed to download files up to 10 MB. - checked download speed - my supposed high-speed dsl is about 1.51 mbps. This is the same on my work laptop (running windows 7), and on my daughter's MBP. But I was able to download the large update at a steady rate of about 90 kbs. - changed location name in network preferences. - deleted cache, reset safari. - downloaded Mozilla and tried that. I can download the files to my work laptop, but don't have any way to get the files from the laptop to the imac. the laptop is a work computer, so it has a lot of restrictions built in. Calls to applecare have not been that helpful, but I was able to download a 144 MB update from the download site, but the next one I tried did not work. My most recent call to applecare resulted in the suggestion that I bring the computer in for a genius appointment. I have spent so much time on this already, and carrying the computer into a mall will not be easy for me. Any other suggestions? I saw a suggestion for Applejack. Thanks!
