Jul 31, 2017 In the Data/Library/Logs/Mail I have 541 files (!!), some of them very huge. I have deleted a 75 Gb file and another of 13Gb, but I still have files from more than 9Gb (ten file obver 1Gb). I have changed passwords in my accounts and even to access my hosting proividers.

Ask Question Asked 5 years, 5 months ago. Active 2 years. With.Library you get your default library location.
Ever since Lion (OS X 10.7), Apple has hidden your personal Library folder (/Library) by default. In Lion and Mountain Lion (OS X 10.8), you could make the folder visible, but it required some work.

This appendix describes technologies that fill very specific roles. As a rule, if your goal is to have a process running while the user is logged in, you should almost always use either a launch daemon or agent, as described in Creating Launch Daemons and Agents.
Running Agents Before Login
Most software that displays a user interface does not run prior to the user logging in. However, in some rare cases, it may be necessary to create a graphical agent that does.
By default, OS X does not allow any application to draw content prior to login. If you need to do so, your agent must call the setCanBecomeVisibleWithoutLogin: method on its windows. For more information, see the documentation for that method and the PreLoginAgents sample code.
Authentication Plug-Ins
Authentication plug-ins are the recommended way to perform tasks during the login process. An authentication plug-in executes while the user is logging in, and is guaranteed to complete before the user is allowed to actually interact with their account.
You might write an authentication plug-in if you need to programmatically reset an account to a predetermined state, perform some administrative task such as deleting caches to reduce server utilization, and so on.
To learn more about writing an authentication plug-in, read Running At Login.

Login and Logout Scripts
Important: There are numerous reasons to avoid using login and logout scripts:
Login and logout scripts are a deprecated technology. In most cases, you should use
launchdjobs instead, as described inCreating Launch Daemons and Agents.Login and logout scripts are run as root, which presents a security risk.
Only one of each script can be installed at a time. They are intended for system administrators; application developers should not use them in released software.
One way to run applications at login time is to launch them using a custom shell script. When creating your script file, keep the following in mind:
The permissions for your script file should include execute privileges for the appropriate users.
In your script, the variable
$1returns the short name of the user who is logging in.Other login actions wait until your hook finishes executing. Therefore, your script needs to run quickly.
Use the defaults tool to install your login script. Create the script file and put it in a directory that is accessible to all users. In Terminal, use the following command to install the script (where /path/to/script is the full path to your script file):
To remove this hook, delete the property:
Use the same procedure to add or remove a logout hook, but type LogoutHook instead of LoginHook.
Note: If no plist file exists for com.apple.loginwindow, this method will not work. This file (/var/root/Library/Preferences/com.apple.loginwindow.plist) does not exist on a fresh installation until the user changes a login window setting (such as turning on fast user switching).
If you must install startup scripts programmatically, you should consider providing a copy of this file containing the default configuration options. Then, if the file does not exist, copy that default configuration file into place before running defaults. Again, application developers are strongly discouraged from using login or logout scripts, because only one such script may be installed.
Bootstrap or “mach_init” Daemons
In OS X v10.3, a mechanism similar to launchd was supported to allow the launching of programs either at system startup or on a per-user basis. The process involved placing a specially formatted property list file in either the /etc/mach_init.d or the /etc/mach_init_per_user.d directory. Such daemons also are sometimes referred to as mach_init daemons.
The use of bootstrap daemons is deprecated and should be avoided entirely. Launching of daemons through this process may be removed or eliminated in a future release of OS X.
If you need to launch daemons, use the launchd facility. If you need to launch daemons on versions of OS X that do not support launchd, use a startup item.

Hello and welcome to my User Tip
Sometimes you have a problem with System Preferences or something related to it, like it remembering your screensaver or desktop selection, or perhaps it won't launch or launches funky.
This procedure is for deleting the 'preferences' file(s) that is located in your (hidden) User/Library folder that can resolve issues like this.
When the computer is rebooted and the associated program launched again, it recreates this file, but blank of preferences, thus since it's rebuilt it's free of problems.
This procedure also works for other programs like iPhoto or iTunes, or whatever that stores a preference file (.plist) in the (hidden) User/Library folder, the procedure is the same, just sub out the program your having problems with .plist file instead of the System Preference .plist file below.

Known preference files issues:
com.apple.systempreferences.plist (corrupted/not launching System Preferences)
com.apple.desktop.plist (corrupted/not working desktop picture changes)
com.apple.safari.plist (safari issues)
See the Steps #12 and #13 for OnyX and it's preference file checker to find other corrupted preference (.plist) files that might be causing your issues.
So we are going to delete a preference file in a hidden folder, this will only affect the preference file, not your personal files or programs.
1: Go to the Finder and select Go menu and Go To Folder
2: Now paste or type
~/Library/Preferences
3: Press GO! and a folder will appear
4: Scroll down and find
com.apple.systempreferences.plist com.apple.desktop.plist (or whatever program your having problems with)
5: There may be two of the same named file, drag the one you can to the Trash can
6: Restart the computer and open System Preferences (or problem program) and reset all your preferences again
