This question already has an answer here:
My employer has given me a new laptop (Windows) with good specs, but it has been too slow. At home I use a Mac and I think I would be more productive with one at work. The office uses Windows because of knowledge of other senior colleagues who do the setup and managing database.
The boss told me on my first day that restriction of software and unavailability of tools are also a factor, but I know that all the software we use is available on the Mac as well.
How can I ask for a Mac laptop while not sounding bad or making him or myself look bad?
