+# Understanding zsh error on macOS (2025-11-11 17:23Z)
+
+_**User (2025-11-11 14:46Z)**_
+
+@zsh (530-531) why do i get this error on macos

+
+
+This is a macOS privacy/permissions issue. The terminal doesn’t have permission to access your Downloads folder, even though you own it.
+
+## Why This Happens
+
+macOS restricts terminal access to certain directories (like Downloads, Desktop, Documents) unless the terminal app has Full Disk Access. This is separate from file permissions.
+
+## How to Fix It
+
+1. Open System Settings (or System Preferences on older macOS).
+2. Go to Privacy & Security → Full Disk Access.
+3. Click the + button.
+4. Add your terminal app:
+   - Terminal.app: `/Applications/Utilities/Terminal.app`
+   - iTerm2: `/Applications/iTerm.app` (if installed)
+   - Or whichever terminal you’re using
+5. Toggle it ON in the list.
+6. Restart your terminal.
+
+After that, `ll ~/Downloads` should work.
+
+## Alternative Workaround
+
+If you don’t want to grant Full Disk Access, you can:
+- Use Finder to navigate to Downloads
+- Or use `open ~/Downloads` to open it in Finder
+
+The Full Disk Access setting is the proper fix if you want terminal access to these directories.

+Notes for SC 24 booth talk on Lmod
+
+* Lots of new stuff this year
+* Support for Dynamic LMOD_MODULERC and DOWNSTREAM Conflicts
+  Explain why this was requested
+* Support for new function depends_on_any()
+* Support $MODULES_AUTO_HANDLING env var
+  if set then prereq() becomes depends_on()
+  and prereq_any() becomes depends_on_any()
+  Something that Tmod already supported.
+* zsh and ksh working together (finally)
+  The fight over FPATH
+* Improvements to sh_to_modulefile command and source_sh() function
+  Old code sometimes did setenv("PATH", "..." which would clear PATH
+  on unload.  This should be fixed now.
+* Generate actual manpage via pod2man
+* % module --dumpname -> Lmod
+  Could use module --version but --dumpname is easier
+* Now show module extension when doing "module --terse avail"
+* Coming Attractions
+** Changes on how Lmod tracks module usage
+*** Old way was efficient on space but not on time
+*** Old way stored all old module usage
+** New way is one table with duplicate data (module names, paths etc)
+*** But it is easier to remove old data
+*** Faster to search
+*** Using mysql.connector.python as replacement for python MySQLdb interface
+** Support for hide{} and forbid{} to match Tmod
+** Support for LMOD_SHOW_HIDDEN env (all, list, avail, spider)
+   Set this variable if you don't want to have to remember to do:
+** Some sites want to hide modules that are loaded on your behalf     
+   I don't like that.  I want to know what module have been loaded.
+   I can set this variable to not have loaded modules hidden from me.
+** Support for no-reversible module functions   
+   setenv, load etc when unloading a module
+   setenv{"A","B", mode={"unload"}}
+** Support for TCL 9.0+
+   works now as separate fork-exec. Needs work to be integrated back
+   into Lmod.
