Has SB-TB4K KVM Switch upgraded firmware since introduction?


  • There are some reviews on Amazon and B&H Photo saying

    Thunderbolt 4 KVM Switch has fried MacBook and Mac Thunderbolt ports and motherboards.  Others says the unit has overheated even in rooms at 70F.

    I like to (safely) use this KVM switch with my Apple Pro Display 6K Display with a 2019 Intel Mac Pro and a 2023 M3 Max MacBook Pro.

    Please advise.

     



  • @Paul Chiu We applied a fix for uncertified devices and that's the unit sold today. If your devices are Thunderbolt-certified, there was never an issue. The units can get quite warm but operate normally in a normal, open air room.


  • @Sabrent Would the 2019 Apple Pro Display XDR be Thunderbolt-certified and safe to use with the SB-TB4K?

    It has one Thunderbolt 3 USB-C port, which connects to the Mac end.

    Also, are these upgraded units ready to ship and ETA to New York City?


  • @Paul Chiu This list is a good place to start but it doesn't list everything. However, it's my understanding that all Apple products are TB certified, but I will verify. If you do get the KVM I can check the SN for you. Everything we sell should be revised as a precaution.


  • Hey @sabrent.com could you please check if my docking station has the revised firmware applied? The serial number is 47786080301111.


  • @Andre Kay It is my understanding that the newer revisions starts at x1275


  • i just received the switch from amazon and its serial number starts with 4782, similar to @Andre Kay's. so, i received an old version? kind of a bummer...


  • @bogner.f The originals started at 4778608300001, ones higher than 47786080301794 have the native fix but some below this were handfixed. 4782x should be newer.


  • I have a unit with a lower serial number.  Is there a way to get the fix?


  • @kevin Please contact technical support/customer service via the website, thank you!


  • G’day, I had some free time and wanted to try a simple online casіno. Browsing discussions online, I discovered chicken road. I started with their Slots game, and the first spins gave me nothing. Then I placed a bigger bеt and finally hit a solid win. Players from Nigeria can enjoy special bonuses, which made the gameplay even more exciting. Now it’s my favorite place to relax casually.


  • What’s up, crew? I saw an ad on a news site while planning a fishing trip to Whangarei and decided to register. I have been on a losing streak for what feels like an eternity and was almost out of funds. Using vegashero changed my fortune in an instant during a quick session. I landed a sequence of wins that put me well into the green. I earned enough to be very happy and finally feel like a winner. It was a great experience.


  • One thing that surprisingly helped streamline my workflow was switching focus to pari-app-match.in for quick breaks between sessions, keeps things light without the hardware headaches. Sabrent's later updates seem to have fixed a lot though, no major issues on my end anymore.


  • Hardware safety remains the top priority when managing complex KVM setups with Thunderbolt-certified devices. For those looking to take a quick break between technical configurations, exploring the PAK500 platform provides a responsive mobile betting experience optimized for high-performance Android devices. Ensuring you have the latest firmware for your switch and a verified app for your gaming needs will keep your workflow smooth and your entertainment secure in 2026.


  • Sometimes it’s not even about the odds, but how smooth the whole experience feels. When everything updates quickly and you don’t have to dig around for matches, it makes a big difference. That’s why options like Win Bet for Bangladeshi players can feel more convenient if you just want to follow events and place bets without overcomplicating things.
