Ever since I bought this particular MacBook Pro back in 2023 I've been asking this question, and I've spoken with Apple Tech Support numerous times. The reply has always been - no Hard Disk access is the normal, use the Documents folder. So unfortunately for me and my machine the dye is cast.
The advent of System Integrity Protection (SIP) means users will have no access outside of /Users, and specific other paths. This means allowing access to two of the Applications paths, but not to the third, for instance.
These access prohibitions are an intentional and deliberate choice to keep updates easier, to allow detection of attempts to modify macOS itself, to allow better integrity including easier rollbacks when an update fails, and to keep malware somewhat more constrained.
Last I checked, Windows PCs didn’t have Windows itself located on a cryptographically-signed separate storage volume. Not past the now-discontinued SteadyState, or Kiosk mode, or setting up Unified Write, or an app such as Deep Freeze or a rollback to a checkpointed guest state. macOS SIP just write-locks macOS itself, even while running, always.
In a manner of consideration, macOS now operates in some ways similar to the ROMs in the Apple II from a few years ago. You could write to RAM, but the contents of ROM are not modifiable. With the expected mix of RAM and ROM, you can’t write everywhere you might want. (Yeah, you could bank switch ROMs for add-on third-party RAM on Apple II and then write where you want, not all analogies hold perfectly.) Downside of using ROMs was needing to physically ship and manually swap ROMs, if something needed to change. The macOS SIP scheme means macOS can be updated without the equivalent of shipping and installing new ROMs, but also largely remains protected against accidental and malicious writes.
Thanks for the link regarding Apple Music and iTunes. I'll give it a try. My issue is that only Apple purchased music is playable on your iPhone. The computer, no problem.
I have purchased music, subscribed music, and music I’ve ripped from my CDs loaded, and it works. Works fine, though not entirely without glitches, as an album I’ve previously downloaded and then more recently purchased from Apple is showing double tracks, and I haven’t bothered to sort that out.
Exactly how purchased, subscribed, and ripped music works (and it does work) depends on where your library is located (iCloud, or local to Mac or PC), and on whether Apple Music (Apple Music the service, not Apple Music the app), or iTunes Match service, or cable sync, is in use.
And also on whether you previously had stuff on the iPhone or iPad that wasn’t loaded into the device from your current music library, and want to keep that.
P.s. First computer Tandy 1000HL, second Mac Plus. I've been in the Apple ecosystem for quite some time. :-)
With some of the helpers around here, that makes you somewhat of a newbie. 😉
