Hi,
I just started trying to use windows steam on crossover recently and I have yet to fully start up Steam.
I'm on a 2008 MacBook.
OS X 10.7.5
Processor: 2.2 GHz Intel Core 2 Duo
Memory: 2 GB 667 MHz DDRs SDRAM
Crossover version: 12.5.1
I installed steam by opening Crossover, going to Install Software -> Supported Applications -> and clicking Install.
Didn't have any issues with the installation but once I login and verify this computer with a new code it quits out of steam. I've tried this several times without any success. I also tried using the tip to remove 'ClientRegistry.blob' but that didn't seem to help either.
Let me know if any other information will be helpful!
