Screen flickering with Slim? Please check this out



  • Thomas Sanders


    I had this problem with my brand new MacBook Pro 16" and Hyper Drive Slim 8 in one, which was connected with a mini DP to DP to a dell U2412M monitor. The external monitor was flickering every 10 seconds.

    I followed these instructions, and the problem is now solved.

    Only downside: I lost a couple of hours finding the problem and solution, and you need to install Windows immediately to a new MacBook :'(

    I noticed in Windows, the screen didn't have any flickering, before updating the firmware. So it's a Mac OS only problem.

    Thanks for the clear instructions!

    Followed instructions but get "Initialize GPU library failed".

    I need to run Windows to update a product I bought for my Mac?????

    Hahahaha this joke ! You must run Windows to upgrade your new-but-broken Mac product !

    I'm using a windows machine, and the VmmUpdater software does not find the device. Any other option?

    Hi All

    The firmware update procedure was a bit confusing to me .....

    I'm new to MacBook and HyperDrive so all the steps in the procedure implied that I would have to install Windows to my MacBook (Bootcamp, etc.), something I have no clue about doing (or desire to do - at the moment)

    I have a Lenovo T580 with Windows 10 installed ... with a Thunderbolt 3 / USB-C port

    Funny thing is that the Lenovo T580 did not have any Monitor flickering issues with the HyperDrive Slim 8-in-1 HDMI port, only with my 2019 MacBook Pro 16" i9...

    I connected the HyperDrive Slim 8-in-1 to the Lenovo T580 USB-C port and ran the VmmUpdater.exe app.

    The app would indicate which firmware the HyperDrive is currently on.

    I then selected the new firmware leaf_Gopod_V14_1230-SST.eeprom

    It takes a few seconds to update.

    I restarted the Lenovo T580 and unplugged the HyperDrive Slim 8-in-1.

    When the Lenovo T580 was started, I reconnected the HyperDrive slim 8-in-1.

    Just for interest sake, I ran the app again.

    The app confirmed that the new Firmware was loaded.

    I then connected the HyperDrive to the MacBook.

    I can confirm no flickering issues observed since the updated firmware was loaded.

    It would be easier to update the HyperDrive Firmware via a Windows Laptop/PC with a USBC-C (graphic capable) port, instead of the MacBook Windows 10 Bootcamp method.

    Thank You

    This is a pretty poor excuse for a solution. I'm not going to jump through hoops because you can't put out a firmware update that will run on OSX. Instead, i'm going to never buy anything from your company again. I buy a lot of devices for Macs through you as I'm an iOS engineer that runs several teams at an enterprise software company. I will also stop recommending your products.
