Can I use a Shure Beta 58 vocal mic with my PowerBook MacIntosh laptop? I have an older Shure Beta 58 mic purchased in 1996 that I would like to use as an external microphone in lieu of th built in mic on my PowerBook laptop.  What interface do I need?  I would like to use it for conferencing software like Zoom.  I am also supposed to make an audio recording of some songs to send to a virtual choir project.
An XLR (the connector on the Shure mic) to USB audio device is what you need. There are several varieties on the market, but this is a very handy gadget which has worked well for me.
