Does your video use a Variable Frame Rate? See https://community.adobe.com/t5/Premiere-Pro/Variable-frame-rate-video-with-Premiere-Pro/td-p/4601935
If yes, use https://handbrake.fr/ open source transcoder/converter to convert to Constant Frame Rate

This computer is also a mac, if that makes a diffrence. thanks for your help in advance.

Make sure Default Input in the Audio Hardware in the Preferences is set to No Input.

This is most common with clips that are variable frame-rate ... in other words, the actual number of frames per second varies throughout the clip. If the program playing that clip back uses a straight number of frames per second, the audio will vary of course.

So ... was this from a phone or screen-capture recording? And is it VFR?
