What permissions should the .gnucash files have on Mac? Some seem to be 644

777 seems wrong, but 644 seems not enough, though the .gnucash file on my Desktop
seems to open OK as 644. “Group” seems to be something called “Staff."
If you're changing permissions using chmod, you may want to use the
symbolic form for the permissions (using similar conventions to what's
shown in in the "ls -l" command) rather than the octal value of the
permissions bits.
So, for example, 644 can be set by using:
chmod u=rw,go=r accounts.gnucash
(u=user (yoU/owner), g=group, o=others).
There you can use + or - instead of = to add or remove permission bits.
The octal bits are:
400 = user/owner read
200 = user/owner write
100 = user/owner execute (the execute bit on a directory is lookup
permission)
040 = group read
020 = group write
010 = group execute
004 = others read
002 = others write
001 = others execute
Add (or or) the values together to construct the octal permissions
number that can also be used in chmod. So 777 is everyone can do
anything; and 644 is owner read/write, group and others read only; 600
is owned read/write, no permissions for group or others.
FAT file systems don't support the U*ix permissions, so when a file is
copied from a FAT filesystem, the permission bits are set using a mask
set when the FAT filesystem was mounted. That defaults to 777.
