No. The facts you are not going to like:
- serial numbers are platform specific
- platform switches only apply to the latest version (CS6)
- CS4 no longer is eligible for upgrades to CS6
- even if none of this was an issue, CS4 has limitations and issues on current versions of OSX. It's showing its age...
In short: No way other than sign up for CC or buy CS6.
