The biggest problem is with Sprints website. This problem started last week, sometimes the site comes up and I can't log in (none of the links work) and most times it doesn't come up at all, it appears to start then stalls. I have tried resetting Safari multiple times with no help. I contacted Sprint to see if they changed something with Macs and they were NO help. I have a Mac air, iPod and iMac and none are able to get in. Everything else from the web works fine. Running 10.9.5 on the air and all the updates are up to date.
