Really should be in OffTopic, but Mac is the safest to use with BTC applications on it. I use linux sometimes though.
that's a myth, mac is not less secure at all, they are all about the same, the secuirty of a desktop depend mostly on the person using it
True.
Many people tend to believe that Mac OS is more secure than Windows because you hardly see any viruses for Mac.
The truth is malware developers want to target the largest user base to make their 'hard work' worthwhile, so they target the Windows ecosystem.
You hardly see viruses for Mac, because bad guys target it less than they target Windows.
