New to Mac

[JasperHiggins]

Have just begun the transition form PC to iMac. 1) DO I need to add security such as McAfee as I did with windows software? If so, does the McAfee subscription I already own apply to Macs as well. 2)While using the mouse sometimes the display suddenly jumps to high zoom mode. I'm not sure what causes this or how to get it back to normal view without closing the window I'm in. 3) how can I put more than one screen on the display at a time?

Hi,

DO I need to add security such as McAfee

Defiantly not do not install any antivirus software.

I would recommend Malwarebytes from here.

Try a double tap

how can I put more than one screen on the display at a time

If you do not mean monitors but desktops this is done with the Mission Control feature on your dock.

And welcome to Mac.
