Keeping iTunes music library on an external drive in Catalina
I didn't update when OS 10.15 was released because I read that in Catalina iTunes music files now had to be on my MB Pro's hard drive and could not be on the external drive, which is where my 600GB library is currently located. However, I spoke with an Apple Support tech earlier this week who said that isn't true, and he promised to send me instructions on how to set up iTunes on Catalina with the same set up I'm using now. Unfortunately, I didn't receive an e-mail from him so wonder if anyone can direct me to the Apple Help page(s) that describe the process.
