I am running v.10.0.3 on Win 7 64bit and I am notified that v.10.5.4 is now available for download. When instructed to download, however, it will not do so. I have stopped all Apple IoS services but this makes no difference. Anny clues ?
Thanks for that but, in the interim, after 2 days of trying and as soon as I posted my request for help, the download worked. The power of thought, I think. Thanks for the swift response though.
