I'm currently using 5.0.1 on Mac OS 10.10. I just got an update notice from 1password. Here's what happened:
I think there is some technological confusion with some links at AgileBits just at the moment. So far as I'm aware the current version for OS X on Yosemite is 5.0.2 and certainly not 5.1.1. I suggest waiting a little while then trying again (1P5 > Check for Updates...).
Got it, but the download link at
bottom of https://agilebits.com/onepassword also not working.
I rebooted and it allowed an update ... it loaded 5.0.2
I'm having the same issue on my iMac running Yosemite. Every time I click the update button it comes back with the reply "Download Failed. Expected status code (200-299) got 404.
Sorry about this, we had a glitch on our downloads service where it was pushing the iOS 5.1.1 changelog to the Mac channel. We've fixed it already and it should be all set now.
The latest update is 5.0.2 and if you're running that already, you should not see any more updates when you check for updates again.
