Apple's ARM-Based Macs To Support Thunderbolt (theverge.com) 137

Posted by BeauHD from the no-need-to-worry dept.
tlhIngan writes: For those worried that the transition Apple is doing to ARM-based Macs will drop Thunderbolt, Apple has stated that they will continue to support Thunderbolt. This was a worry since Thunderbolt is primarily an Intel design (formerly known as Light Peak) with Apple collaboration, and that none of Apple's ARM based devices support it (not even the ARM Developer Transition Kit).

        Unfortunately ethernet isn't an alternative mode for USB4, you still need a dongle.

        Of course if you are in the Apple ecosystem you have to deal with USB and Lightning, or just resign yourself to charging up those headphones every day. If they are going to force wireless then they could at least include a Qi charging pad on the phones and laptops. Samsung phones have Qi charging.

          IEEE 1394 / FireWire had an ethernet mode. Cable length was limited to 4.5 m, but that would have been enough to reach a switch/hub at a desk or on the wall. It's mostly dead on consumer electronics now. I think it hit the technical requirements better than USB 3, but it struggled as a secondary port in a world where ubiquitous interfaces and compatibility are important. Every time USB shifts between connector types they run the risk of losing their market dominance. I have computers that don't have USB-C c

      Dingles come and go. It mostly depends on what you want to run. Right now a single USB hub is your docking station. The issue is that so many thing are on the old USB Random shape brigade.

      When Apple went to intel, you had to buy a FireWire adapter for SCSI and a 400 adapter for old 800 devices. SCSI provided true plus and play and true chaining, so it was useful. Now everyone has hubs.
