How should I answer this question? Can I ask for financial needs or the macbook that I want to buy?
Of course. I'd say there's a few categories you can mention here:
Pay - This is probably not what they're directly getting at - I would take this as "how can we make your life better at work", not "how can we fairly compensate you for the work you're doing". But if that's a factor, then sure, mention it.
Working conditions - Are you happy with the time that you're working? Would you like it to be more flexible? Would you like a block of time you're not disturbed in the day / week?
Physical items - Macbook comes under this - but don't forget other hardware too. New monitor, new mouse / keyboard, KVM switch if you want to use the kit for two machines, better headset for videoconferencing, etc. But don't forget the non-tech items either - new desk, new desk chair, heck even a nice fan if it gets hot where you work - all important stuff.
Software / licenses / tools - Don't forget this! This is often the cheapest category, and often the one that could make your life easiest. Are you stuck using Eclipse and want to use IntelliJ? What the full Atlassian suite for tracking bugs / source control etc.? Want Stackoverflow for teams? Mention it.
Events - Training, conferences, networking events etc. - if you want tickets to these sorts of things, or training organised for interesting stuff you feel would be useful to your role, then ask for it.
There will of course be more, and I'm certainly not saying you should mention all of the above, it's just for ideas - but don't be afraid to ask for what's going to make you more productive. The costs of most of the above is likely completely insignificant compared to your salary, and for a company, that means it's a great investment (you'll likely perform better and be more loyal as a result if they give you what you're after.)
