MATLAB will not save any files PLEASE HELP MAC OSX

MATLAB will not save any files after I have put up my Firewall. I have tried everything. I contacted MathWorks and they could not help me. I have homework due Friday and I need to know what I have to do to get Matlab to save files again. I have already tried taking down the firewall and that does not work. I have gone so far as uninstall Matlab then reinstall and the files would save, but as soon as my Firewall went back up the problem persisted. PLEASE HELP PLEASE!

I have my firewall up on my Mac, and it works fine. (OSX 10.10.5)

Are you trying to save to a non-local drive, or are you using a networked MATLAB?

[Walter Roberson]

What happens when you attempt to save files? And which directory are you attempting to save them in?

I am trying to save them on my desktop in my CS 1371 folder. I am a student, I don't know anything about code.(just so everyone knows my level of expertise and understanding) so I have no idea if it is a networked version. I got it from school. It came in a zip drive format.

A Google search of "CS 1371" and "MATLAB" suggests you are at Georgia Tech. Can you use the technology support center there to help you?

[Kamania Ray]

OIT (Office of Information Technology) after I told them what I had done to try an fix the issue (Check write permissions, repair disk utility, re-install...ect) that I should probably work there. Basically we re-intsalled it once again (for the third time) and that only made Matlab work until I got home. I have been able to create text files, open them in the command line and then save them back into the file folder as a .m file. However, I cannot create a new file in Matlab and then save it. It must be a already existing file.

What happens when you CD to a different directory (let's try /tmp or /temp or wherever you put temporary files) and try to create a file there? Does it work or does it throw an error?

[Walter Roberson]

What happens if you use another method to create the file, such as going into Terminal (look in the Applications / Utilities folder), and at the prompt there, cd to the target directory and then "touch" or otherwise create the desired file. For example,

cd ~/MATLAB
touch newfile.m
echo > newfile2.m

While you are in that directory at the Terminal command window, please show

ls -led .

(The above is a command that ends in space followed by period; those are part of the command)

[Kamania Ray]

Steven Lord: error

Walter Roberson: 0: group:everyone deny delete

- I have no idea what it means, but here it is...

[Walter Roberson]

Somehow you gained an Access Control List (ACL) on the directory. At the terminal window (as described above) cd to the directory you want to be able to save in to, and then command

chmod -a "group:everyone deny delete" .

where the period is part of the command. Then use

ls -led .

and see if any more entries show up. Once you get down to just something like

drwxr-xr-x  21 roberson  staff  5406 13 Aug 00:07 .

with nothing like that "0: group:everyone deny delete" after that line, then all of the ACL have been removed.

It is plausible that your firewall is putting these kinds of ACLs in every time it is run, so you might end up having to do these kinds of commands again later, until you reconfigure the firewall.
