I'm rewriting a 330-page book, copying each session's output back and forth between OS 10.6.8 Snow Leopard on a MacBook Pro and 10.7.5 Lion on an iMac. I'm doing this to meet deadlines, which requires me to work in two locations. Unable to "Save As" on the iMac, I have used the Duplicate command to assign a progress number to the book before copying it to the MacBook Pro, where I perform additional work on the manuscript. From there it goes back to the iMac, and the back-and-forth process continues.
Tonight, thinking I have completed three weeks of work, I ran through the page thumbnails on the Pages siebar an discovered the 330 pages had grown to 660. Apparently a more recent version had been added atop an earlier one. Unfortunately, the same date and progress number has been assigned to both as if it were a single document. I also discovered this double-up situation goes back at least six versions. This means changes made on prior versions may not be included on later ones. The only way I can produce a finished document from this mess is by arranging side-by-side comparisons of every line on every page, six times! This looks like a full-time job that may take weeks to accomplish!
Can anyone tell me how this happened? How can I avoid it reoccurring?
(Because I'm frustrated at missing the deadline, I'm ready to trash the iMac and Lion as an unusable combination of Apple hardware and software that has disrupted my entire business. The lack of a "Save As" command and reliance on auto-saving is a widely-known disaster among Mac users, and I'm unaware of any Apple efforts to undo the damage. Moreover, the auto-save activity in Pages causes the program to freeze for a few seconds after every touch of the Return/Enter key on the iMac. It slows down my writing to the point where I've had to compose some projects with TextEdit and paste it into Pages afterwards.)
