I noticed that since updating to macOS 10.15, I get duplicate search results for some apps (due to the new read-only filesystem).
If we take Spotify as an example, is there any difference between launching either of:
or is the second option semantically equivalent to a symlink?
Clarification My question is not why there is a second folder, or why I get duplicate search results. My question is whether there is any difference in behaviour when looking at how apps from the two file locations are treated by the system (for example, does macOS impose additional restrictions on apps launched from /System/Volumes/Data?), or whether they can be treated as identical.
