A few were work laptops, so they came with the suite of poorly-written corporate spyware agents which I suspect was the culprit.
On my personal laptops the cause could be all the accumulated junk I installed. Apple's refusal to support legacy software may help out since it seems the old software doesn't want to run on new hardware.
