I use a TI-84 Plus (recently upgraded to version 2.55) and a TI-89 Titanium on a regular basis for school, and I create my own programs for my benefit. I have connected both calculators to my PC with TI Connect multiple times without a problem to sync programs and rearrange files, but I want to use TI Connect X for Mac to use the new version with a program editor. Upon installing TI-Connect and connecting my calculator(s) to the computer, I receive no indication that my calculator is seen by the application. Only after turning off and then back on my calculator do I get this message:

 

TI Device Explorer Error.png

It reads: "Alert - A device was connected, but we could not communicate with it for some reason."

 

This has happened with both my calculators every time I try. I have uninstalled and reinstalled, used different cables, downloaded the software again, and connected to different usb ports, all to no avail. I sought out help from TI for this, and it was concluded that the problem was probably with my MacBook Pro because I am still able to connect to my PC and my friends' Macs, under the same conditions.

 

Does anyone know of a reason for why my TI-84 Plus and/or TI-89 Titanium cannot connect to my new MacBook Pro using the TI Connect X software?

MacBook Pro, Mac OS X (10.6.7), Calculator: TI-84 Plus and TI-89 T.

    I have also used TI-Connect for Mac back in the old days when I was also programming for TI Voyage 200.

    It's a issue related to your MacBook Pro's USB Ports I think.

    Have you tried to hook up other kind of devices via USB?

    This is just a guess, but I suspect TI needs to update its software for compatibility with the latest MBPs, or perhaps with the latest version of OS X.

     

    If your USB ports weren't working, the alert message wouldn't appear.

    Andrew, are you still having this issue or did you figure out what the problem was? I too am having the same issue with my TI-89 Titanium. I do not have the cable that came with the calculator and attempted to use a standard camera cable that's USB to mini. I'm curious to know if this has anything to do with it. So, did you have the original cable (or purchase one through TI) or did you use a generic cable like did? Thanks in advance.

    Ok, so I went to Best Buy in an attempt to buy a TI cable hoping this would fix the problem. One of the guys from the Geek Squad told me TI's accessory products are not proprietary so it shouldn't matter what cable I used and directed me to the cell phone area for a generic USB-to-mini cable as they did not sell TI cables. I bought one for good measure just to make sure I didn't have a bad cable at home. STILL the same problem and error. I sent TI a message through their website trying to get help on the issue and this is what they said:

     

    "First, I would like to inform you that Texas Instruments has not tested this software on your platform. It was last updated to work with Macintosh 10.6.4 OS. While we will continue to troubleshoot any issues that may arise I am not able to guarantee that a solution may be available.

     

    Since you have Snow Leopard OS I am assuming that you either have 10.6.5 - 10.6.8 OS, if I am incorrect please correct me so that I continue troubleshooting. At this point, our software developers have become aware of an issue with our software and your platform. They are working on possible solutions for a possible future update to the software. Unfortunately, I do not have an estimated time frame as to when this update may become available. I do apologize for any inconvenience that this may have caused."

     

    I definitely have 10.6.8 so I guess I'll be waiting for the software developers to do their thing. If you've got 10.6.4 then you should contact TI for more help.

    Update to last:

     

    So, I remembered that my wife's MBP has Windows XP w/Bootcamp installed on it. I install the TI Connect software from TI, connect my 89, and viola. Why didn't I think of this sooner.

     

    One caveat: the cable I purchased from Best Buy still seemed to not allow TI Connect to see my calculator. So I reverted back to my camera cable which has what I believe to be an adapter (small cylindrical object close to mini-B end) and everything worked fine.

     

    It's definitely a software issue on TI's Mac OSX developing side of the house because everything works as advertised with Windows; even on a Mac.

     

    I still wonder, though, if the name brand TI cable would resolve the inconsistent cable issue I still seem to have. But everything's working for me now so I'm happy enough...

     

    Hope this helps.

    If it helps any, I don't think it's the cable.  This is happening for me as well and I have the original USB calble from TI.  I just updgraded to Lion and unfortunately I didn't try this prior to installing Lion so I can't say for sure that it would not have worked, but it sounds like any version above 10.6 is not supported yet by TI.  Hopefully they will fix this soon.  I really don't want to have to install windows or parallels just for this one thing.

    I'm in the same boat... but with my 2011 MBA 13.3". It's the same problem and it sounds like it's related to the OS (I'm running Lion as well). The message "A device was detected but we could not communicate with it" comes up when I turn the calculator on after being plugged into the USB. I hope TI can figure this out asap-- this makes it challenging to effectively use it in class as I'm teaching.

    Hi

     

    I am trying to update my TI 84 plus as i am a student and i need this new app for a new chapter and i seem to ba facing the same problem. Does this mean it is the problem with mac recognising my calculater and i should try with a pc instead?

  • jasonVC Calculating status...

    Im having the same problem, im running mac os x 10.7.1, on the ti-89 titanium for calculus 2. It seems all the applicaton of integral apps were all updates to the os, so i connected the usb cable and installed the product cd but it wont recognize the device. so then i tried to install the disc on an old mbp but it ate the cd(guess it's been broken), so now im really screwed.

    I just tried the current version (1.8) of TI Connect in Lion -- it's TI unConnect -- no luck. I ran a USB probe; the calculator is recognized by the Mac. The problem is TI's software. When it will be updated is anyone's guess. But keep watching

    for a new version.

  • joseluisfromvail Calculating status...

    It is DEFINITELY the TI -Software. I had exactly the same problem as you with my new MacBook Pro with Lion.  I figured it had been working OK with my old Mac that had Leopard so I got my old Mac out of the closet and tried with that one.  Worked perfectly.

     

    So... Your solution is to try with an older Mac, go to a friend's house or something if you don't have one anymore.

     

    Good Luck
