Hi. Listen. I have my good working MBP running 10.5.4 with all my apps i use every day. I just bought a new Mac Pro and instead of starting all over i just used a 100% clone from my MBP to my new Mac Pro. The Mac pro runs perfect from what i know. But my question is. Is that okay to do ? Are they using the same things. From what i know they both use 10.5.x but different system files. But all files are on both systems, right. They just load what they need when it boots, yes ? Or is it not a good idea. Hope someone have some answers becaouse the Mac Pro runs fine of the MBP clone. Thx a lot for the help.
