After several days of playing with my new logos 4. here are the 3 options that I tested.
1) Run Logos 4 on my mac - Alpha 5 seems little more stable.
2) Run Logos 4 on my parallel - I got to use the pc version of logos and liked it very much
3) Run Logos 4 not on parallel but on boot camp - this ran logos the fastest and I am enjoying the program.
I like using logos on parallel because I can swithc back and forth to my mac applicaitons. But, I like logos on boot camp because it runs faster and greater response time looking up things.
For now, I am settling on boot camp. But, I can't wait for the final version on the mac.
