Simple question:
Why is Apple any better than Windows just because it is based on Linux?
Both are commercial closed environments with proprietary APIs. Microsoft are criticised for all the security fixes and the monthly updates but at least they are addressed. Yes they could handle it better in Windows 10 (it is just crap that you cannot turn off or restart any more if there are pending updates).
Is Windows genuinely less secure? Apple are notorious for their secrecy and trying to bury anything that might bring them into disrepute. People will have strong opinions but I am not sure an opinion is the same as the facts.
I tried to move a relative to Linux (Mint I think) on a Toshiba laptop and we gave up. The support overhead was worse than Windows in getting a printer, camera and a few other USB devices to work. Only when Linux has resolved those problems does it genuinely become viable for the average non-tech user. As it stands the realistic options are Windows or iOS.
