Done it! The command is: <sudo chown -Rv myname filename> I also tried <sudo chmod -Rv myname filename> in order to ensure that I had permissions for all the contents of the folder, but was told that 'michaelgraubart' was incorrect — perhaps because I already had the permissions. At any rate — thank...

That tells me what to search for and possibly get an answer to in the Apple Discussions forum. Thank you very much indeed.

So if I uninstall the SMART software (using the SMART uninstaller) and, possibly, examine invisible folders and remove the objectionable one, should that do it? I don't in fact really use the not-so-SMART stuff. You have been immensely helpful. Thank you very much — also in anticipation of one more ...

Those two new commands have, I think, perhaps given me a clue. This is what transpired: Last login: Sun Feb 15 00:32:45 on console Michaels-Mac-mini:~ MichaelGraubart$ ls -al ~ | grep config drwxr-xr-x 3 root staff 102 28 Oct 22:01 .config Michaels-Mac-mini:~ MichaelGraubart$ SELECT ALL -bash: SELEC...

Thank you again. I'm afraid I don't know what to do with 'SELECT ALL', but just entering 'mkdir -p ~/.config/inkscape' produces 'Permission denied', so that appears to be the problem.

Now that's really useful. Thank you once more. Could I ask for one more kindness? I am not very familiar with entering data into Terminal. Is there any chance that you could give me the full command so that I can just copy and paste it into Terminal? Thank you very much in anticipation. Alternativel...

Thanks for the explanation. But honestly — I do deny myself some things (I won't go into details!), but certainly not the ability to create directories (is that what Mac users call folders?) in my home folder. And, as I said in my first post, I am the only user of this computer and no other person h...

PS (re 'Cannot save' post): I have just tried again and, mysteriously, there is now no longer a problem with saving! But I should still be grateful for any information about the 'Cannot create profile directory' message. Does this in any way limit what I can do with Inkscape?

I have just installed Inkscape 0.91 on my Mac mini, running Mountain Lion (10.8.5). I have also installed XQuartz 112.7.7 in lieu of X11 and — as instructed — have logged out and in again. I can now open Inskscape, but initially a message appears: Screen Shot 2015-02-14 at 16.47.19.png If I click OK...
