I’m not having a good experience with Mavericks on my 2008 iMac. I think the upgrade messed up my keychain in some way. Mail, Contacts and Calendar (my Google account) no longer sync — I’m constantly prompted to enter passwords over and over again. Removing the account and adding them back doesn’t resolve the issue. Since my contacts and calendar are hosted by Google I don’t have access to them locally.
Facebook, Twitter, Flickr integration are also not working. I’ve removed them from the “Internet Accounts” panel in System Settings but the system won’t let me add them back.
The iCloud Keychain won’t activate at all. I get an error message that my Mac failed to contact the iCloud server. Sigh!
What’s annoying is that everything works fine from my wife’s 2013 MacBook Air. I don’t have any problems using any of the new features from my account on that MacBook.
In the mean time, I have switched to using AirMail and I may also switch my contact over to Cobook. AirMail takes a while to start-up but once it gets going it does a great job. I especially like that I can attach documents directly from cloud services like Dropbox and Google Drive. Cobook also has an iOS version. I like that close integration.
Anyone else having OS X 10.9 issues?
Google recently announced that it would start including individual users’ names and photos in some ads. This means that if you rate some product positively, your friends may see ads for that product with your name and photo attached—without your knowledge or consent. Meanwhile, Facebook is eliminating a feature that allowed people to retain some portions of their anonymity on its website. Bruce Schneirer
If these features don’t sound particularly beneficial to you, it’s because you’re not the customer of any of these companies. You’re the product, and you’re being improved for their actual customers: their advertisers.Bruce Schneirer
