alright so after about a day of usage i'm considering going back to 10.5.4. there are way too many annoying little things happening in 10.5.7 and i personally don't think the upgrade is worth it to me. i've spent way too much time getting hackintosh to work in the first place let alone having to now deal with the following issues:

so far:
every time i boot up, it keeps finding a 'new' ethernet connection in network preferences. the internet works fine each time, but its annoying.

my usb webcam has stopped working in 10.5.7 using iusbcam 2.2.5 with ichat. it just crashes when trying to open a video chat with someone. in 10.5.4 it worked completely fine.

my mouse all of a sudden randomly stops working at random intervals. i have no idea why. i just have to unplug it and plug it back in to make it work. this never happened in 10.5.4.

i can't even open 'system profiler' anymore. just says "There was an error while gathering this information." worked fine in 10.5.4?

time machine has stopped working! i tried the efi flag/add to boot 'fix' but it didn't work for me. this is a HUGE issue for me. worked completely fine in 10.5.4.

other than not being able to use safari 4 (i use firefox anyway), i don't see any legitimate reason for me to stay at 10.5.7. just giving some feedback on my 10..5.7 experience so far.
