Hello,

To help you with this matter and check why cannot detect macs, there are a couple issues we can try, but first and most important:

1) I need to know the model / EMC of the computer that give you a hard time detecting and we can check the pinout of the debug port and confirm the adapter number and orientation;

2) Just to rule out a potential issue: All of our adaptors are hard to damage I'm sure that even if adaptor 2(blue) and adaptor3(yellow) look similar, you know they are not interchangeable as they they have different pinout;

3) Only component that could have issues: Is the flex between those adapters and SPI connector. Just look it at NOT to have any sharp twists / bents on it

4) And to completely rule our adaptors: Do a quick visual inspection, not to have anything between pins (check both sides), the soldering should look clean, and no solder bridges between pins or any debris. If you see anything, use a soft brush to clean them.

This is all I can think of for now, and after i get the model and EMC I could check more.

Also, macs can be picky about in what power mode you connect to them. For example on my personal A1466, i have to remove mag safe, remove battery, then connect mag safe, wait for it to start (spin fans) then press power button to shut down, and only then put connector in, and I can connect to it. In other power modes the mac's only SMC will control the data lines to the chip and wont release the control to the HDBOX.
