This will be a small article, but I thought I would share my findings about Auto Save and Versions in Mac OS X Lion.
I recently updated my 2011 model MacBook Pro to Lion. I have not had any problems, but I did discover one thing that caught me way off guard. The Mac apps that have been updated to support Auto Save and Versions no longer have a Save As option in the File menu when working with existing files.
I opened a photo in preview the other day to re-size it and save a smaller copy to email it. I am sure there are a ton of ways to do this, but I use a method I am familiar with. I noticed after I re-sized the photo that there was no Save As option in the file menu. And, after I closed the photo, I then realized my original had been re-sized. So, I then had to teach myself how to use the Revert to Save feature to undo the re-size. After a little experimentation, I discovered the Export option, which appears to be what they are calling Save As now.
I have to say, once I get used to this new feature, I am sure I will like it. I have never used Time Machine on a Mac before, but this Versions feature is pretty cool. But, there will be a learning curve to get used to it.
For more information on these features, check out Apple page on it.
