For those looking to use ACI with Crossover Office you will be able to install ACI 2010. It wasn't thoroughly tested though, because it is outdated. Once you update your install with the latest service pack for UAD updates (sp2.8 was tested), the install will no longer work. If you are not doing work for Fannie Mae or Freddie Mac and don't need UAD, you may be able to make it work for you. I have not found any of the integrated sketchers to work however.
