Need to find professional income tax preparation software, capable of handling 1065, 1120, 1041, 990, etc. preferably PPR compatible with Mac's OS

Question

Need to find pro tax prep software compatible w/Macs. My software maker, Drake, does not have Mac version. I've checked Pro-Series (no) and maybe 1 other. I don't want to spend Lacert kind of $$ (neither do the majority of longtime Lacert users apparently). Obviously, no Turbo Tax, Tax Cut or any other commercial, deduction & crdit missing commercial software. They would ned to have the ability to 1) convert a few years of Drake to their program, 2) Covert files created on PC to files that 10 OS could use. Also, would like them to have reasonable PPR program, free efile, free unlimited states, capable of 1040, 1065, 1120, & (S), 1041, 990. Built in tax knowledge base. I'd be eternally indebted to you if you found sometghing as intuitive and value oriented as Drake but for OS 10. BEGINNING TO THINK APPLE bends over backwords for artistic tools but not so much business tools. Too bad, I've had a few tax returns that have bordered on art.
I will likely need to add Parallels & Windows 7 OS, preferably 64-bit to this Macbook Air. If so, I do not think I have sufficient memory or storage so would like to download & install onto NFTS (sp?) formatted 1TB HD. I do not know if hard drives, USB hubs, Optical drives etc. that work w/ Windows (as long as you choose correctly btwn SATA & IDE) will work on MacBook Air. Help greatly appreciated. So if you happen to know any pro tax prep software ompatible w/ OS 10 and/or, you could give me some info on what characteristics peripherals would need to have to use on MacBook (I'm hoping that most are inrterchanheable but my hoping ain't gonna make it so. OR if you know any great deals on Parallel-I saw some promos but not from reliable places. If I could find on Bradsdeals or Coupon Cabin I'd feel safe. I've seen  an Apple ad for a bundle of software w/ some other decent parts (Snagit) . I'd love to find a promo that applies to the bundle and download all 9programs for $9.99 (right). Too many questions, sorry for any protocol violations.  As you might have noticed, a keyboard is high on my agenda- I hate laptop keyboards though Apple's seems better than most. I also hate using scroll pads. Much rather have mouse. Real challenge is to find Bluetooth OS 10 keybrd that has numeric keypad. I wonder if the financial dept. @ apple uses keyboards w/ no numeric keypad, saw one that started at $99. I spent all the $$ I have on a MacBook, none leftover for overpriced peripherals, esp. w/ 2 kidfs going off to college in Sept.
Thanks for allowing me to whine & ramble. Feel free to call me on any breach of protocol as I am 1st time poster.
Thanks for your time and consideration, I HOPE I'M CORRECT IN MY GUT FEELING THAT I've joined the forces for good by switching. Too many PCs ruined by malware.

Bill I've also run into a very similar problem, I own many Macs but I've had a PC for Tax Stuff. My PC broke and I refused to buy another one so I began to search for an alternative. Window's Emulators have given me so much trouble with my Tax Software.
However, I've since found out that Intuit has a cloud based tax solution that works with a MAC because it's all done online. Which means you'll need a reliable internet connection whenever you want to prepare a client's return.
It's suppose to support all of the major returns (1040, 1041, 1065, 1120, 1120S and 990)
I've yet to use this solution, but it's the best thing that I've been able to find so far. This is what I'll be using this upcoming Tax Season.
So I figured that it would be worth mentioning. Good Luck!
