Q: cant pair divice with macbook air

Correct, as it is not a supported protocol.

iOS: Supported Bluetooth profiles

you can't sync or transfer files over bluetooth you need wifi or an usb cable

Even a USB cable doesn't help me. I was emailed a PDF, opened it on my iphone5c and wanted to transfer it to my 2013 macbook air. (Wifi temporarily unavailable where I am.) Bluetooth didn't work - I had the same problem as noted above. But neither does the USB cable. From the MBA there is no way to see  the PDF on the iphone (let alone to transfer it).

I've registered my complaint directly with Apple, but just in case someone from the company reads these boards, I'll repeat here:

APPLE, WOULD YOU PLEASE TAKE CARE OF THIS BLUETOOTH PROBLEM? THIS IS ONLY ONE OF MANY DISCUSSIONS ABOUT THIS DATING BACK AT LEAST TO SEPTEMBER 2013. SEAMLESS CONNECTIVITY BETWEEN APPLE DEVICES HAS ALWAYS

BEEM THE MAIN REASON WHY I BUY YOUR PRODUCTS. YOU'RE SERIOUSLY SLIPPING HERE, FOR NO GOOD REASON, AND YOU WILL LOSE CUSTOMERS.

Apple doesn't monitor these forums for feedback.

Apple has never supported Bluetooth connection between iOS device to computer.  Why are you expecting that to change?

And the pdf was emailed to you?  So... forward the email to an email account you can check on your computer, or check the original email on your computer and download it.  Why is this an issue for you?

I understand Apple does not monitor these forums. That is why, as I said, I already registered my complaint directly with Apple.

Why do I "expect it to change"? I don't expect; nor do I not expect. I'm neutral regarding expectations. I hope, however, as do many. And it's not an unreasonable request: given Apple's slogan "It just works", and their highly touted connectivity among all their devices, this seems a ridiculous exception that is a real inconvenience. Especially since, as I indicated above, USB connection doesn't help either.

Thank you for your suggested workarounds. However, they won't help me. To clarify: I need to print a hard copy of this PDF in the next two hours. I cannot print directly from my iphone. I could print from my computer, but obviously I need to get the document to my computer first. Wifi is temporarily unavailable where I am. There is no cable connection either. Therefore my computer is cut off from the internet, so I cannot check email from it. The only way to get the PDF onto my computer is to transfer it from my iphone. Since Apple does not support Bluetooth connection (which is ridiculous, as noted above), the only other way is via USB cable. But Apple does not support this either (which is even more ridiculous). So there is no way for me to get this PDF to my computer to print it out.

Apple should support both bluetooth and USB compatibility for file transfer between their devices. Judging by the number of discussions on this, it's neither an unusual nor unreasonable request.

I did find one workaround; one way I can get the PDF to the computer: from the iphone, open the PDF in ibooks; then sync with the computer via USB. This will import the file to ibooks on the computer. However, there is a problem: if I open the PDF in ibooks, it is automatically saved to icloud. This may not seem like a problem, but it is: some files — such as this one — are confidential; one may not want it in the cloud. In the case of this PDF, I could get in big trouble for allowing a copy to be in the cloud.

In general, I've noticed a trend (not just with Apple): as they add ways to use the cloud (which is good), they remove ways of doing the same tasks via older methods, e.g. via USB cable. In essence, one is forced to use the cloud. I've spoken with several Apple representatives about this, and it's almost as if they cannot comprehend why anyone would NOT want to use the cloud. They say "but now you don't have to use a cable; the cloud is much more convenient. And it saves a backup for you!" Of course the cloud is convenient, but for any number of reasons I might not want to use it. They should not force one to — they should not remove other simple options that were working just fine.
