    Hi all,

    As mentioned in the title, I can't get my new M8 (AT&T) not to connect to my macbook. HTC sync manager times out after some time and displays evice unavailable.Please reconnect your phone.

    I already tried a second macbook-the same. Also android file manager does not recognize the phone either. Really strange and any help from the community would be great!

    Thanks,

    Hard reset seemed to resolve this problem! Thanks!

    I tried hard reset, it works while booting/loading and becomes unrecognized afterwards. Help.

    I had this problem with the M7 but I can't remember what I did to get ANDROID FILE TRANSFER to work.

    EDIT: I don't want to use hTc's Sync Manager. PITA.

    I had a similar issue. I had an old copy of HTC Sync Manager. It had a green icon. I went and installed the new one, blue icon, and it worked great.

    If you restart the computer with the phone still plugged in, Android File transfer will work.

    That's great to know. I have used HTC Sync Manager successfully but much prefer Android File Transfer. The small inconvenience of a restart will be worth being able to use AFT now.

    I had the same problem with my SGSIII. After the first restart, it worked every time.

    Reboot fixed my htc one m8 as well. Once the reboot is complete, start the android file transfer app again and wait a few. Same version that I have has installed for one year on the Mac (Mavericks OS) and did not require any updates. I was apprehensive with the HTC sync app, looks clunky.

    a little late in the game, but a fix none the less, so i wanted to post it. and since this is still popping up on people's phone, i figured it was worth sharing.

    after a ton of searching and trying all of the options available. i finally found some files on a windows computer that solved this for me. i couldn't find the same files on a mac, so i am unsure if they are available, but they can be copied from a windows install.

    in the directory, c:\program files (x86)\htc\htc sync manager\ there are several apk files. AndroidHtcSync.apk and four more labeled with numbers after them. i copied all of those apk's to my phone, and tried to install them on my phone through a file explorer, one by one. one installed, the rest could not. but the fact that one installed, was promising. Well, after that install, htc sync manager on my mac, could once again connect to the m8. So it appears that the AndroidHtcSync2.apk that was on my phone, was corrupted, or otherwise not installed or running correctly. installing it again, fixed it.

    what a hassle and what a sad state that HTC themselves could not figure this one out.

    Hi all,
    None of the posted methods worked for me, so I figured I'd post the fix I finally came across for anyone who might be in the same situation.
    HTC ships its phones with USB debugging enabled by default. Every time I plugged my M8 into a computer, it would ask if I wanted to trust the computer, even if I had told it to "always trust". I figured this might be why neither HTC sync manager nor Android File Transfer could see my phone. So I went into device info, tapped the build number list item a bunch of times to enable the developer menu, and disabled USB debugging. This fixed everything, oddly enough. Just something else to try for anyone still having issues.

    I had the same problem, with my MBP 15. Try using a different USB. For whatever reason my left side USB will not talk to my android period. Switched to the USB on the right side of my mac and it works every single time. Hope it works for you too.
