I am shooting tethered with a 1DsII via EOS Utility 2.4 and Lightroom 1.4.1 on OS10.5.1. Canon does not support the 1Ds, 1DII, 1DIIn or 1DsII and 10.5.2 if you read the fine print on the EOS Utility 2.4 download page. I installed the 10.5.2 update and it killed the connection. Now that 10.5.3 has been released I am curious if anyone has been able to shoot tethered with the 1DsII.
Thank you,
Tony
