    Thunderbolt 3 Splitter?

    I was wondering if anyone could shed some light on something I've been trying to accomplish. I have a 16" MacBook Pro and the LG UltraFine 5K monitor which only allows Thunderbolt 3 for it to work with the Mac. This is fine, though the Mac needs 96 Watts and the monitor over Thunderbolt 3 only...

    Yes the 16" MBP does run quieter with an eGPU on an external Monitor

    I share this information with you because I saw it coming up in several Threads if the 16" MBP connected to an eGPU does (and if how much) run quiter compared to having the monitor connected to the internal dGPU. And it does. Obviously. Quite a bit, in my personal use case - Webdevelopment (CPU...

    MBA 2015 turns on only with SMC reset after being shut down...

    This last week, my Macbook Air Early 2015 didn't respond to the power button for the first time. It took a 15 minute battle with the power button. After that, whenever I shut down my notebook, I had the same problem. The power button didn't answer and the screen was wholly black, so I learned...

    My current setup is a MacPro5,1 with a GTX Titan X (6+8 pin). Currently using a 6-to-8 pin adapter for the 8 pin input on the card. Would I need to pick up another 6-to-8 pin adapter since the EVGA PowerLink has dual 8 pin inputs?

    Do you own a Talos II?

    I believe the PowerPC community needs no introduction regarding the brilliant Talos II, Talos II Lite, Blackbird and the upcoming Condor product lines by Raptor. Knowing these computers being insanely high-performant, cost-competitive, privacy-respecting and completely blob-free (unless we count...

    How do I find out MBP 2014 power?

    I've got to report the electrician rMBP 2014 power so he calculates what automatic breaker I can afford. I've heard the unit for power is watts (W). I've also heard outside my country the power is measured in A. https://support.apple.com doesn't state anything like this but MagSafe 2 specs...

    Random question. I recently moved into a new house that was built a long long time ago. (Zillow says 1900, but I don't know). So the house has older wiring, not sure if it's dirty yet... However, Do we need a power conditioner on our systems? Would a UPS do the same thing? If so how many watts...
