I can use mac if I'm forced to do but my sanity is worth more than some extra money I can get doing so

and seriously, using slow and noisy machine with poor multitasking and overall terrible UX WILL slow me down considerably, it's not worth it also for employer

and you know what? I've done it before already and been the happy guy in the office laughing at all the trouble people forced to use macs had

EDIT: ofc if I'd know beforehand that mac is the only option I simply wouldn't apply to that place, there's no reason to make your own work lower quality
