Turn Off Filename Extension Warning

In Leopard, Apple fixed an annoying aspect of working with the Finder in Tiger. Previously, if you changed a file's extension, the Finder prompted for confirmation. But since no one has ever accidentally changed a filename extension, Apple thankfully added an option to turn that warning off in the Leopard Finder's preferences. Choose Finder > Preferences, and in the Advanced screen, deselect Show Warning Before Changing an Extension.

 
 

Chapter 12 of “Take Control of OS X Server” Now Available

Send Article to a Friend

We’re heading into the home stretch with Charles Edge’s streamed “Take Control of OS X Server,” and this week Charles looks at the essential Caching and Software Update services in Chapter 12, “Software Updates.” These two services are conceptually similar: they cache software updates from Apple and redistribute them locally over your network to reduce unnecessary bandwidth usage and increase performance for users. So what’s the difference, and why would you want to run one, the other, or both?

The Caching service is easy to set up and run, works for Mac and iOS apps and updates, and needs no client configuration. It’s a no-brainer for any network, no matter how small or large, and if you are running OS X Server, you should enable the Caching service. In contrast, the Software Update service requires more work on the server, plus non-trivial client configuration, and it works only on Macs and only with software updates from Apple. But, and this is why Software Update is still useful, it enables you to specify which updates your users can install, so you can vet each update before releasing it. Even just being able to prevent users from updating instantly could save you some significant support headaches, if a particular update turns out to have some unanticipated problem.

So if you’re looking to reduce bandwidth, improve performance for users, and exert control over which updates your users install, check out this week’s chapter!
