One of the stated features of 10.5.6 is improved performance of TC and TM. I've got a TC and have switched off TM b/c it worked so poorly on my Macbook Air. After about a week I would find that my TM would get stuck and corrupted and cause TM to stall on preparing and then fail to load the drive and then proceed to knock down the wireless network. Has anybody who was having problems with TC and TM in the past upgraded to 10.5.6 and seen improvements? I finally got my wireless network working alright and I'm not quite sure how convinced I am that TM will start working now. Thanks.
