+ | ====== ファイルの保存に関する今までの知識との違い====== | ||
+ | |||
+ | Apple has turned file saving on its head in OS X. //You cannot save a file any more// | ||
+ | |||
+ | This information is not specific to Rhino for Mac, but applies to all applications that implement OS X's Auto Save and Versions. | ||
+ | |||
+ | The following paragraph has been in each recent Rhino for Mac release note, but not everyone has read the article. | ||
+ | |||

+ | |||
+ | Everything below is also stated in the referenced articles. | ||
+ | |||
+ | **Auto Save does not mean autosaving** | ||
+ | |||
+ | On OS X prior to Lion and on Windows computers, the term autosaving means " | ||
+ | |||
+ | In OS X, Apple unfortunately uses almost the same term, //Auto Save//, to describe something entirely different. | ||
+ | |||
+ | **How often is a file saved? ** //All the time.// | ||
+ | |||
+ | This is how Apple describes it: | ||
+ | > Auto Save in OS X saves during pauses in your work and, if you work continuously, | ||
+ | |||
+ | Try the following experiment: | ||
+ | |||
+ | * Copy one of your Rhino models to the Desktop and place it where it will not be covered by a Rhino window. | ||
+ | * Select the copied Rhino file and select File > Get Info in the Finder menu. A file info window will appear. | ||
+ | * Note the Modified time of the file. | ||
+ | * Select the Rhino file on the Desktop again and press Command-O to open the model in Rhino. | ||
+ | * Adjust your Rhino window and your file icon on the Desktop so you can still see both, and note the preview image of the Desktop file icon. | ||
+ | * In Rhino, select some object in the Perspective view. | ||
+ | * Type Option-left arrow then Option-right arrow. | ||
+ | * Rotate the Perspective view a little, so you will be able to tell when the preview image has changed. | ||
+ | * Now, do nothing. | ||
+ | |||
+ | Within 10 - 20 seconds, the preview image of your file icon on the Desktop will change to match the Perspective view of your model. | ||
+ | |||
+ | The same thing happens when you switch from Rhino to another application. | ||
+ | |||
+ | Lastly, your model is saved when you close the model window or quit Rhino. | ||
+ | |||
+ | There are safeguards that are custom to each application to ensure that Auto Save does not happen while you are modifying the model. | ||
+ | |||
+ | **You can no longer save a file** | ||
+ | |||
+ | Or, perhaps more accurately, you cannot decide when your model will be saved on disk. The system is doing it for you instead, and does so all the time. You cannot save a file, because it has already been saved for you. | ||
+ | |||
+ | Apple' | ||
+ | |||
+ | **Command-S does not mean Save A File** | ||
+ | |||
+ | If you are used to typing Command-S all the time to save your model, this is now a //bad habit//, because Command-S no longer saves a file. It does something entirely different, and it is probably not what you want. | ||
+ | |||
+ | Open one of your models and look in Rhino' | ||
+ | |||
+ | Each separate version that you save is retained by the system. | ||
+ | |||
+ | Every time you type Command-S, you add another Version to your file. Pressing Command-S a lot means you create a //lot// of Versions of your file, and you probably do not need or want all those distinct backups in the future. | ||
+ | |||
+ | The system also provides a Time Machine-like interface to look at these saved versions. | ||
+ | |||
+ | **New Models** | ||
+ | |||
+ | If you are working on a new model and have never saved it, then typing Command-S brings up the standard File Save dialog (just as it did before) and you pick where you wish to store your model. | ||
+ | |||
+ | **IncrementalSave is gone** | ||
+ | |||
+ | If you are used to using Rhino' | ||
+ | |||
+ | **OS X Mountain Lion (10.8) changes** | ||
+ | |||
+ | Apple made some additional changes to Auto Save in OS X Mountain Lion (10.8). | ||
+ | |||
+ | In 10.8, Apple changed the File > Save A Version menu title back to File > Save. However, the behavior is still as described above. | ||
+ | |||
+ | Starting with OS X Lion, any standard OS X application has a File > Duplicate menu choice, and this opens another document with a copy of the contents of the current document. | ||
+ | |||
+ | Auto Save constantly saves to disk any changes you make to a model. | ||
+ | |||
+ | In 10.8, there is a new setting in **System Preferences** > **General** for changing that behavior. | ||
+ | |||
+ | **Going forward** | ||
+ | |||
+ | As you work on a model, there will be natural break points or phases in your work and these would be good places to use Save A Version to take a snapshot of your work so far. Remember that the system will also be making regular snapshots of your model about once an hour, so you will have a number of recovery points if you ever need to go back and retrieve previous work. | ||
+ | |||
+ | Apple has fundamentally changed how we are used to working with our documents. | ||
