DL1608 destroying my Mac Mini(s)

I've been doing what you do connecting laptops/iPads/pods to 15/16 on the DL for a while and no issues ever. And I've had to run with phantom enabled while doing this. I do use a dual DI box and mic cables for long runs though, always. This is the DI I use:

When a mixer has both XLR and TRS inputs on the same channel, I've never seen a TRS jack that has phantom - the DL1608 certainly doesn't.
I always carry a bunch of 1 foot XLRF to TRS and XLRM to TRS cables so I can plug line level XLRs into the TRS line inputs anyways. That saves deploying a LOT of DI's - it's not uncommon to use up the four TRS inputs with a couple stereo keyboards and/or the XLR output from a bass amp.
It's unfortunate that the DL1608 doesn't have TRS inputs on all channels - or at least would let you route the 13-16 inputs to any channel strip you want so you could properly arrange the channels to your liking. I believe the X-Air has both of those things? I'm really hoping Mackie will have time to play a bit of catchup with the feature set of the X-Air soon - many things are doable with the present hardware :) and already in MF for the DL32R but disabled when a DL1608 is connected :( .

The DI box you're using as most others block 48V phantom power. The 48V + is on XLR 2,3 with the shield as the return pin 1. TS or TRS connectors can be used on inputs 13 - 16 on the DL. There is no 48V on any TS/ TRS connectors. For the stereo 3.5 mm T & R are the two signals with a common return S. They are unbalanced signals. TRS/TS inputs also have a 20 dB pad to accommodate line inputs.

There are several ways to do this, nearly all wrong (even some which employ a DI box). I'd be interested to know precisely what type of lead/adapter was used?

The cabling is 1/8" Stereo to XLR adapter with XLR to XLR. All cabling is from Monoprice. All internal wiring is correct i.e. no shorts or unintentional grounding, infact this worked for 4 MONTHS then POOF. I'm thinking the isolation transformer mentioned above might be the correct answer. But the $64k questions is WHY after 4 months? I'm going to give Mackie Tech a jingle and see if there is some secret button somewhere.
I sincerely appreciate all of the replies.

Can you translate that for a volunteer that is doing the audio that doesn't know diddly? ;D I'm assuming that inserting the appropriate box in-between eliminates the phantom power.

RoadRanger and WK;
Thank you both for your help and answers. I really appreciate it. The beauty of analog mixers like my ZEDD, has dedicated stereo 1/4 in and RCA. This makes it very simple to connect most stereo devices, like keyboards, consumer audio, without eating up channels which can be used for mics. As in the ZEDD, 4 XLR and 2 stereo pairs. I guess to save money by adding separate stereo pairs Mackie went with XLR and combo jacks. Which I have made do with for sometime, very happily.
