No they are not, only All Access or LiveSafe offer cross-device protection.
Check the product pages Virus Protection and Security for All Your Devices – PC, Mac, Smartphone and Tablet | McAfee
There is also "McAfee Internet Security for MAC" and "Family Protection".
Yosemite is, I believe, not yet fully covered except by the trial version available online..
As far as your other Mac problems go probably best to post on a specialist Mac forum.
You best speak to Technical Support regarding coverage as I was not aware Total Protection would cover a Mac, it certainly isn't supposed to....unless you are running Windows on the Mac.
See link below. It's a free phone call or you can use online chat. Customer Service can also clarify which packages work on what system or device and they are also a free phone call and listed below
