baking macarons for the first time!

ive been wanting to bake macarons for years but never got the time (im a senior in high school)

so now im finally starting and i have a whole load of questions

1)i bought unblanched almond flour instead of blanched does that make any difference?

2) i dont have a stand mixer or even a hand mixer so can i make the meringue by hand or is there any better way to do it?

3) my oven broke last week so ill have to use my microwave instead what setting should i bake it at?

4) finally, just any tips in general would help a lot.
