MACOS system console app
https://www.howtogeek.com/356942/how-to-view-the-system-log-on-a-mac/#:~:text=%E2%80%9C~Library%2FLogs%E2%80%9D%20is,for%20low%2Dlevel%20system%20services.
Your Mac keeps system logs, which can help diagnose and troubleshoot problems with macOS and your installed applications. These logs are stored as plain-text log files on your Mac’s system drive, and macOS also includes an app for viewing them.
To view your Mac system logs, launch the Console app. You can launch it with Spotlight search by pressing Command+Space, typing “Console,” and then pressing Enter. You’ll also find it at Finder > Applications > Utilities > Console.
The Console app, also known as Console.app, is like a Windows Event Viewer for Mac.
More logs are available under Reports. To see application crash and freeze logs, click either “System Reports” for system applications or “User Reports” for user applications. You’ll see a variety of logs with file extensions like .crash, .diag, and .spin. Click them to view them in the Info pane.
Admin user account mgt
The admin user can add other new accounts to the local system
When adding a new account, you create the new account name, password
set the user type to standard or admin based on the authority you want the new user have to manage the local computer
after that, have the new user login and go through normal account setup
User account vs Login Keychain passwords
https://support.apple.com/en-us/HT201609
The password of your macOS user account might not match the password of your login keychain. Either create a new login keychain or update it with your new password.
After you or your Mac administrator resets the password of your macOS user account, your Mac might ask you to update your keychain password or enter the password of your login keychain. It might also tell you that the system was unable to unlock your login keychain. That's because your login keychain is still using your old password.
If you don't know your old password
If you don't know your old password, the solution is to create a new login keychain.
If you know your old password
If you know your old password, use that password to update your existing login keychain:
Open the Keychain Access app, which is in the the Utilities folder of your Applications folder.
From the list of keychains on the left side of the window, select "login."
From the Edit menu in the menu bar, choose “Change Password for Keychain 'login.'”
Enter the old password of your user account in the Current Password field. This is the password you were using before the password was reset.
Enter the new password of your user account in the New Password field. This is the password you're now using to log in to your Mac. Enter the same password in the Verify field.
Manage users from CLI with DSCL
To change Mac OS X's users and groups from the command line you want to use a command called dscl.
To create a new group (change groupName to your group name - avoid spaces, shortusername should be your short user name):
dscl . -create /Groups/groupName
dscl . -create /Groups/groupName name groupName
dscl . -create /Groups/groupName passwd "*"
dscl . -create /Groups/groupName gid 33
dscl . -create /Groups/groupName GroupMembership shortusername
If you want to use Workgroup Manager; you need to open the application and login onto localhost using your username and password. (This all assumes you're a local administrator). Once in the program:
- Click on the Groups tab on the left side. The icon with multiple people.
- Click New Group from the toolbar
- Enter a name, and set the Group ID: to 33
- Click on the Members tab, and then press the '+' button and drag and drop your user name into the list.
- Press Save, then quit the program.

https://appletoolbox.com/seeing-error-operation-not-permitted-in-macos-mojave/
Error: “Operation not permitted?”
Working with your Mac’s Terminal Utility but getting the error message “Operation not permitted?” Are Terminal commands that used to work in macOS High Sierra and Sierra not working?
this error on advanced commands like super-user sudo and change ownership chown commands but also on simple commands like the list directory command ls and others. What a mess!
easy to fix–we just need to update some of your Mac’s security and protection settings!
SIP still allows access to some directories, like ~/Applications, but totally locks down others like ~/System or ~/usr.

how to disable itunes permanently
https://superuser.com/questions/88614/is-it-possible-to-uninstall-or-disable-itunes-in-os-x
If you want to just disable it, run sudo chmod -x /Applications/iTunes.app
It won't work anymore.
If you want it back, just sudo chmod +x /Applications/iTunes.app
On more recent versions of macOS, you may need to disable SIP:
- Power off your device
- Power on your device while maintaining ⌘ and R pressed
- Once you reach the recovery system, select Terminal from the Utilities menu
- Type
csrutil disable and then reboot
If you want to revert that back to the original protection, run the same steps but replace with csrutil enable at step 4.
Check the current status with csrutil status in any terminal window.

man screen
By default, each command
begins with a control-a (abbreviated C-a from now on), and is followed by one other keystroke.
Screen does not understand the prefix "C-" to mean control. Please use the caret notation ("^A" instead of "C-a") as arguments to e.g. the escape command or the -e option
managing terminal windows
split >> CMD - D
change >> CMD - ] or CMD - [ // switches terminal instances, NOT terminal panes
close split >> SHFT - CMD - D
Use cmd + d for vertical split and cmd + shift + d for horizontal split
To navigate between the vertical splits in left/right or up/down fashion use cmd + [ and cmd + ]
I recommended iTerm 2 because of these features.
Also, I like the autocomplete feature which occurs when you press cmd + ;
Features in short include the following:
- Split Panes
- Hotkey Window
- Search
- Autocomplete
- Mouseless Copy
- Paste History
- Instant Replay
- Configurability
- Full Screen
- 256 Colors
- Unix-like
- Readability
- Mouse Reporting
- Growl Support
- Exposé Tabs
- Tagged Profiles
- Multi-Lingual
using 2 terminal window instances together
If you like to work with your terminal windows in fullscreen, you can use macOS' built in screen splitting feature like so:
- Open two terminal windows
- Toggle one of the terminal windows fullscreen
- Activate 'Mission Control' (default: F3)
- Drag the second terminal window onto the first's fullscreen space
- Enjoy your vertically split fullscreen terminal windows
You can switch keyboard focus between terms with ⌘-[ and ⌘-]

After Catalina upgrade, Bash man, info cmds missing
https://apple.stackexchange.com/questions/221597/os-x-el-capitan-man-command-not-found
step 1 - upgrade xcode to latest version from app store
Apple publishes the source code for the open source parts of OSX. So the source for "man" is retrievable from https://opensource.apple.com/tarballs/man/ . The latest version (as of this writing) is v1.6c. Provided you have at least the Command Line Tools installed (you can run xcode-select --install to get them if you don’t):
curl -LORf 'https://opensource.apple.com/tarballs/man/man-16.tar.gz'
tar -xzvf man-16.tar.gz
cd man-16/man
# Undo an Apple patch that adds a dependency on 'xcselect.h',
# which is something that Apple doesn't appear to distribute.
patch -R -p0 <../patches/PR11291804-xcode.diff
./configure --prefix=/usr/local
make
make install
That done, the man binary should be available at /usr/local/bin/man. Also note that you might need to run hash -r to clear the hash table of any instances of /usr/bin/man that may be lingering there from the last time you ran man before the addition to /usr/local/bin/ will be picked up.
