    I'm so used to Thunderbolt,SSD's and USB 3.0 I don't know what I'd do if I had to go back to slower technology.

    Albeit for an expensive price. Well worth it imho.

    ... Perhaps this will stop my MBPr from freezing when I connect the Thunderbolt/Ethernet adapter.

    Backup first

    I'm going to be sure to backup my iMac first after what happened last time there was a Thunderbolt update. I need to be prepared for another kernel panic. My rule of thumb is to always backup before installing an update that requires a restart.

    10.8.3 is Mountain Lion is it not? Do they mean that, or 10.7.3?

    Can we finally use the iMac as an external display to a thunderpolt PC now?

    I really get the sense that Thunderbolt is another Firewire. Very seldom used, high cost due to the circuitry needed.

    Just curious but those of you who have Thunderbolt on your MBP's would you rather those would have been extra USB 3.0 ports instead?

    EDIT:// Ok you can stop replying now :p - I get it, you guys love Thunderbolt.

    no issues for me

    I use that nearly every day. No problems, whether I plug it in when the machine is in sleep (lid closed, plug in, open lid) or not (lid open, plug in).


    Hell no. Hooks up to my thunderbolt display really nicely. And I have a second thunderbolt in the box next to it, just waiting for me to pull it out. The lack of a mess of wires is much much appreciated.

    I wonder if this affects Thunderbolt -> HDMI adapters in any way. :confused:

    I've depended on Thunderbolt for quite a while on my MBP for my 10Gbe, Sonnet SSD RAID and Blackmagic cards. No problems here. I'm not updating.

    It is not another FireWire. FireWire was quite popular and not that expensive.

    Good lord no, for certain tasks Thunderbolt is well worth the price premium especially if you're earning a living on devices that connect that way.

    You're right in a way though, Thunderbolt much like Firewire will almost certainly not be the consumer standard as USB (in this case USB3) is fine for the majority of users and doesn't incur the extra costs associated with implementing the standard. But for those that need the benefits of that standard (or who can afford to pay extra for the best possible performance) it's a god send. The problem is that some (and there are dozens of examples just on these forums) don't get what it's for or why it's expensive and start complaining while the simple fact is for them it's a luxury item and a USB 3 device would meet their needs perfectly. Actually now that I think about it maybe a better analogy would be the old days of SCSI versus IDE.

    I use it to connect to the Thunderbolt Display, which makes for a very nice laptop docking station. The integrated Thunderbolt/power cable drives the display and connects my keyboard, printer, external hard disk and Ethernet. Very convenient.

    No. Such adapters are really Mini DisplayPort to HDMI adapters, Thunderbolt isn't involved.

    I have a Thunderbolt to HDMI cable, and it's working great. Doubt l'll ever update my MacBook Pro. I'll probably never update iTunes either. I remember one update that wouldn't let me play iTunes content on my TV (second display, not mirrored). The next update fixed it, so that's where I'm staying.

    I'm hoping this fixes the sound crackle that occurs when a Mac connected via Target Display Mode wakes from sleep and the random screen blackouts...

    Currently using a 27" iMac with 2 other 27" iMacs connected as displays via target display mode.

    Pro tip: You can use the Audio Midi Setup app to merge the speakers of each Mac connected via target display mode into a single sound card entity.

    I would prefer the Thunderbolt, even if I don't use it often, it is more versitile, hook up displays, USB, drives, ethernet, firewire, etc.. etc...

    I want to stab myself every time I am required to use USB 2 over FireWire 800. I'd imagine in 5 or so years, I'm going to feel the same way about USB 3 and ThunderBolt.

    Yeah, that's usually the case. At first I thought it might be a hardware issue, but there's enough people in Apple's forums and elsewhere reporting it that I think it's just a bug.

    My Thunderbolt port on my mid-2011 MacBook Air 13" stopped working after I installed this update, for both Thunderbolt devices and with a display that does DisplayPort without Thunderbolt. Did anyone else experience this?

    This is what it now says in System Information for that port:

    Status: No device connected
    Link Status: 0x7
    Port Micro Firmware Version: FFFF.FF.FF

    I'm confused, my mid2011 MBA claims Tbolt Sw Udte V 1.2.1 was installed on 2012.06.21.

    Is this an update that is just being rolled out to other devices now?
