At my job we have a software that only runs on Windows (thats what the company says). I have a question because I'm planning to buy a rMBP saturday. Is there a posibility to surpass that and have that software on my rMBP without having a windows installed? remote desktop?
There are many software titles that are Windows-only. You need to separate the function of your software from its function. If the Windows software in question is the only software that performs this function, then you have no option but to run this software.
simsaladimbamba has given you links to two options for running Windows on the Mac. Two more problematic options allow you to run Windows software without Windows. These include the opensource
WINE and
CrossOver, the commercial superset of
WINE. The options are problematic because they can be expected to work on a case-by-case basis but not generally. This is to say that
CrossOver/
WINE may work for your software or it may not.
Even though your software title is Windows-only, the functionality may not be. There is a breadth of knowledge among the members of this forum. Perhaps someone here is family with your firm's software title. It is even more likely that some is familiar with software that performs the same or similar functions.
If you give the name of the software title and the function(s) that it performs, then you may receive more useful assistance.
