Hello Everyone,

I have got a multimedia project. I have made a hybrid CD (macimage) to be able to use it on both platforms with an autorun but unfortunately is not working on older mac’s ( just on 10.5 or above ). I tried nearly everything. It is running well on every Pc’s on the newer mac’s but the older ones doesn’t even recognise the cd. I always get an error message saying the Cd is not readable. I have used CS4 ( and actionscript 2). Is it something to do with the .app file? Shall I use .hqx with an older version? Is it can be the problem?

Does anyone knows what the problem can be?

Thanks for the help 🙂
