I’m sorry that a Mac does things when copying files to a PC or non-Apple device, that crap up the other devices that then have to deal with the issues the Mac created. I’m also sorry that the small Clip+ does not have embedded within it and its small memory whatever is needed to handle the issues that a Mac creates. I’m not sure how much of an issue it would cause to add this, but out-of-the-box universality obviously would be a good thing, if possible.
You’re right, the Clip+ manual and other product information should correctly/more fully state the issue and solution, as discussed here–that potentially would have avoided at least some of your understandable frustration. As you may know from reading posts here, the manual, while graphically nice, has informational deficits, that it would be nice to see addressed (a general continuing and growing issue with consumer product manuals, I find, some products not even including manuals at this point). I’m not an Apple computer user and don’t know how far-flung the issues that a Mac creates are–does the issue get caused by all Apple computers and operating systems? The nice thing about this forum is that it exists, in part, to solve issues such as yours, as has happened here.
Having said all this, you’ve been given the solution, the free Kopymac program, which seemingly fixes the issues a Mac creates, as you note. Perhaps there should be a sticky thread at the top of the forum, readily providing Mac-related information of this type.
And so, while I know that you are frustrated (including in having to use separate software–very understandable), it seems to me that the problem is solved. Yes, it would be nice if the Clip+ would automatically address the problems that a Mac creates. But it doesn’t, either by design (with its small memory, which has limitations and could be the source of the issue here) or overlook. In the end, though, the Mac has created the issue–it’s just that the Clip+ doesn’t address it as much larger other devices might. Computer and device operating systems are not yet universal (and, quite candidly, Apple has been known in the past to be a bit stubborn in this arena).
You might want to complain on the Apple boards about the issues a Mac creates, that other devices and software then have to handle. Or, if the issue continues to bother you, purchase and use a current generation Apple Shuffle with its user interface limitations (and you can purchase 3rd party headphone adapters for the Shuffle, at extra cost, which include the buttons needed to work that player, to address the limitations that Apple introduced onto the player), or purchase the earlier-generation Shuffle, that still easily can be found via a quick search engine search, and live with its own limitations (no screen; as well as no fm radio, no recorder, no equalizer, no microSD slot, and no folder view navigation).
Personally, I’d use the free and seemingly easy-to-use Kopymac software and enjoy the Clip+. (As I said, I haven’t used Kopymac, but: is it any more difficult or troublesome to use than having to use iTunes?) But that’s just me.
