I can confirm that it is working with 10.6.4. I just installed it on my Acer Aspire One (AO532h), and it's working beautifully.
I also have an Acer Aspire One (AO532h) on 10.6.4, and I just cant get it to work. What was your procedure or how did you get this to work. Everytime i install the boot from the file chameleon_nbi084a2.zip, I get stuck in a rebooting loop. I would really appreciate any help you can give me. Thanks
