Tethered to a Mac...

Paul Guarente
Hi All,
It appears tethering to a Mac, especially with a Canon 5D mark 3, seems to be a problem for a lot of us.
I have now come across two postings, by two different people, which should have a positive impact with our problem.
It seems the USB ports that we use have a hierarchy and we need to be tethering via the number one port.
I am trying to find out which is the number one port on my mid-2010 27" i7 iMac, but so far, I cannot find nor get the answer, at least that I can understand.
If anyone out there, especially you techies, can verify this, it would be appreciated by many.
Here is one of the posts that I was talking about.......

Good luck to us all,

    in the past it used to be that I would have to tether into whichever usb port was closest to the power supply (ac connection on mac) those used to have a greater bus output then other ports, but I thought apple fixed that with a firmware update. It could be that some of your USB ports have more bus speed then others..just run a test and tether into each one…see which, if any, your machine gets the most stability out of.

    I strongly recommend using a powered USB hub (Belkin etc) which are inexpensive but really effective. Also, it has enabled me to use a 5 metre extension cable from camera to computer without any issues.

    I haven't had any tethered shoot problems from a Canon 1DX into CO Pro 7.1 since using one.
