I have to renew my computers, I've been Mac user for 11 years and I'd like to get Mac again, but I'm concerned about a couple of things:
1- I don't want any iCloud, App Store and things like that working in any way. So I need to know if they can be hard disabled from Terminal or stuff like that without encountering problems while working. That's because I have to guarantee to my clients that their intellectual property is intact and I don't want to delegate this responsibility to any one other then me (specially not to corporations that delegate their responsibilities to their call centers). And also because Apple Automatic Update, every time I used it, it always have screwed up my OSX installation, becoming slower and buggier (more crashes and problems in general), so if Automatic Update gives these problems I wouldn't even imagine what a App Store could do to my system (considering is much more complex and coded deep inside the OS)
2 - I want to know if I can install in some way OSX 10.6 because 10.7 is very buggy and has much worse performances in every pro application I know and I suppose this is not only because it is a new OS but because the way it is created to stay always synced to a iCloud service and upgraded with the App Store, meaning the OS is always working to update/upgrade its status in iCloud/ App Store. And in general I don't have time to lose because Apple needs beta tester (even thought I think this time the problem isn't of the OS but of what you are asking to the OS... to update (and upload) its status everytime).
I have to use a system that works great, fast, without hassles and very reliable. That's the only reason why I choose Apple.
3 - I don't use the internet in the computer I'm working with (because from every aspects it's better to not use internet in a computer you are working with, because it slowes down everything and makes the computer behaviour really unpredictable. Now I'm using a Mac Pro first gen and it runs like the first day, that's because I've never used internet on it, I have another one near to it where I used internet and works at half of its potential, even thought it is mainteinedly properly, cleaning, repairing, everything)
And I'd like to know if there are any hassle of any kind if you use the computer without internet (like softwares that asks a million of times to connect to internet or other things that do not work without internet, not talking about internet related softwares or function, just I want be able to disable any function that requires internet without having to check every time error messages that says "iTunes Store cannot connect to the internet". I open and close iTunes hundreds of time a day and it is really annoying having to check for something you haven't asked)
So, if in some why I can have a positive solution to all three points I've asked, I'll remain with Apple, otherwise... bye bye Apple
