Hey, i've just made the leap from pc to mac with a lovely white mac book (the medium flavour if you please - it still smells lovely too!), but i'm feeling a bit awkward with it. I consider myself reasonably sharp with pc's - its my job, but what i'm after is that someone could give me answers to the following to help me familiarise myself with my mac; - how to see the chip info (eg speed, etc) as you would in a pc - right click my computer, properties etc - what kind of file structures to mac have - are there equivalents for mac - eg fat, fat32 or ntfs - how much are .mac accounts in UK and are they worth it, i mean, what are the benefits? - could i, if needed use my pc tft to have an extended desktop for my mac? - as i have office 2008 on my mac, do they have the same file extension that would allow me to view the same document on a pc? if not, how severe are the differences? i think these will do for now, i'm sure i'll have loads more questions soon, but i don't want to build a case against my lovely new mac against my tried and tested old xp machine! any assistance would be great. Cheers! i knew i'd think of some as soon as i'd posted this; - as i have leopard, i'm trying to set up the time machine, or at least get the hang of it so when i have more data to back up, it will worth the effort now, the only trouble is when i click on the time machine icon, and choose the disk to back up to, it stays blank - why? also, would it be worth partitioning the HD for the purpose of using time machine. - will i ever need to defrag the HD on my mac? - could you elaborate? - are there any app's that would haelp my transition from pc to mac - i'm trying to avoid boot camp or parallels a- cold turkey i guess thanks - i'l be back for more i sure!
