Hello, everyone from Perth Western Australia, have just joined this forum and have been a Mac user since 1993. Glad to be here. Word of advice, do not upgrade to Catalina as many of your apps which we've paid a fair bit of money for will not work, the likes of Scrivener, which I upgraded not long ago. It also told me that it could not fit my audiobooks in the iBooks app, (my iTunes Library is on an external hard drive) I had to restore my computer back to Mojave. Apple TV has got a bug in it, it shows the subtitles right in the centre of the TV screen as well. My daughter has the same system I have, went to her place, her Apple TV shows the subtitles down the bottom of the screen as it should, but her son's Apple TV shows the subtitles centre screen. This is driving me nuts! Thanks for having me here and for this site.
