they have muti-user mode built in to the files and you can create as many users as you have licenses and they ALL can access the same file and make changes that will show up for everyone in real time. The MAC will run slow even if the file is not open on the PC (PC is the server computer) You run QB and then just access the same file when doing changes and such. If you need some help with networking, let us know - but it sounds like you've already got that part whipped. You can install Quickbooks on both computers (please don't wreck your sanity by trying to run it through the network - you see how slow it gets), and each of you can access the same file, but not at the same time.

Seriously, I admire that you're trying to do this, but it's a really, really bad idea. The purpose is this - say for example you make a change to the file while your boss has it open, then your boss makes a different change, then you save, then she saves - your change will be lost. Most reputable applications 'lock' a file for editing when another user or application has it open. Network your two computers, install Quickbooks on both of them - you may need to buy two licenses for this - and for the sake of all that is holy, don't try accessing the same file from both computers at the same time - that's asking for trouble, if you can even pull it off. Your problem is trying to run Quickbooks on both computers while having it installed on only one.

You can pair the computers together any way you like, although I would recommend using the router you're already using.
