New mac running High Sierra audio and video out of sync
Recently purchased a new iMac 27" desktop. Memory: 6 GB 2400 MHz DDR4. Processor: 3.8 GHz Intel Core i5.
The one BIG bug is that the audio and video are not synchronized. Doesn't matter if it's YouTube, Vimeo or Vevo or whatever. Drives me crazy. Do not know how to even begin to fix this as I am not a technologically oriented person. Any suggestions?
