I just bought a Macbook Pro and I can't connect my HTC One to it. It's very annoying, especially since I already uploaded my music to the Macbook.

You need to contact HTC or find an HTC forum.

That is where you will find people with any kind of experience with HTC software.

Having the same problem, since i just bought a HTC One and looking for the almost the same answer, I'll help you.
This is however more a HTC problem then a Apple problem, HTC should've made sure that the phone is capable with OSX.

Anyway, go to your settings > developers options
and turn these 3 on.
Stand-by (don't make your screen go out while being charged)
USB Debugging

and Allow Mock Locations.

This way it is possible to sync with HTC Sync.
I haven't found a way to make the One act like an USB stick though.

Download and Install

• Step 1:Click Download Now above.
• Step 2:When the download completes, double-click androidfiletransfer.dmg.
• Step 3:In the Installer window, drag Android File Transfer to Applications.

I had this problem, but I solved this easily. First, try and open HTC Sync Manager. It will deny you from entering because it is from a Unidentified Developer.

After you've done that, go to System Prefences > Security & Privacy > General and on the bottom it will say Open anyways. Tada.

Thank you so much.....Your advice really help me.... 🙂.

Great advice! Everyone is always giving stupid or unrelated advice. Your advice actually works so kudos!

No problemo.

No problemo 🙂 I'm glad i could help

TADA is right. OMG so easy. Thanks.

Hi i downloaded

http://www.android.com/filetransfer/

but every time i connect my HTC one to my Mac book Air it says no Andrioid device found.

some help will be appreciated

The only way I could get it to work was by opening HTC Sync, which apparently has no problem establishing the connection, then with HTC Sync open, could use ADB/AFT/etc

Try using another USB connecter.

This is not an HTC problem but an ongoing Apple vs Google/Samsung feud and its ripple effects down the chain. Apple has become less innovative, laggier in its performance and hacknyed in its innovation so the only "good" they are doing is raising hurdles for their only competition. If I were Apple, I would focus on bettering their stuff (and producing dialogue across platforms) rather than wasting their time on sabotaging. The legal suits shows envy and the company now reminds us of Microsoft!

OK Folks i believe i have actually found the solution. I know i am a bit slow but i only got my New HTC One 32gb today (it was free from Three). Like you it would not connect to my Mac or work PC. So here is the way i got it to work. Download Android File Transfer if you have not already got it. Make sure you have USB Debugging setup etc. Now you need to download a free programme called SyncMate. I used SyncMate 4 because i am running OS X 10.7. There is a paid for version of Syncmate but we just want the free version as it seems to contain some drivers that will make Android File Transfer see you phone. Download SyncMate, install it as per usual and hey presto when you plug in your HTC One Android File Transfer should open automatically...BINGO!!! It worked for me which i am really chuffed about as i was just about to ring Three back up to get the phone returned. Let me know if it worked for you too :-)

Cheers dudes

Dear Luis!

The "Android FIle Transfer" was the perfect solution for my problem and I can easily access now the file storage of my HTC One Dual.

Thanks for the help...
