I am brand new to Mac and I like what I see so far but for some reason I think that YDL 5.0 is to the equivalent of like Windows 95 or 98. Can anyone let me know if I am close. I am very proficient in Windows cause thats all I have ever known. I am really wanting to learn EVERYTHING I can about Mac. All of this is for my PS3. I am one to tweak stuff or try things even tho it'll blow the computer up or whatever. I would just like to know these things for common knowledge. I see alot about Leapord 10.5.7 or something like that. Looks great but I don't think PS3 can support it. I wanna know what number like" 10.5.7" is to the equivalent of YDL 5.0. Is it like 5.0.1 or something? Also I wanna play computer games on the YDL OS but I can only find CDRoms that say PC CDRom or whatever, not Windows Specific I know I can't use those, but are PC CDRom ones for Mac? I know its alot but I want to know alot. TY for any info someone might have.
