Mac Settings We should Change

Table of Contents
Tweak Trackpad
Tweak Dock
Tweak Touch Bar
Turn off iCloud Drive
Preferences > General
Turn screen corners into shortcuts
Install apps downloaded from web:
Series: Awesome Tips about Mac
Tweak Trackpad
The settings is at System Preferences -> Trackpad.
Enable “Tap to click” to make Trackpad less noisy at “Point & Click” tab.
Uncheck “Scroll direction: Natural” at “Scroll & Zoom” tab.
So when we move two figures down in the trackpad, the page goes down. <!– - Tap three fingers to look up in dictionary & data detectors.
Tap two fingers for right click: open context menu. –>
Tweak Dock
Go to System Preference -> Dock: - Enable Automatically show and hide Dock - Disable Show recent applications in Dock
Remove Apps from Dock:
We can use Spotlight(Cmd+Space) to open any application instead of moving mouse and clicking the icon in the dock to open it, so usually it’s no much use to keep apps in the dock when not used.
By default, Apples shows a lot of its apps in the Dock, remove them from the Dock: right click on the icon in the Dock, click Options -> unselect “Keep in Dock”
Move Docker on the right side
By default dock shows at the bottom, so it will auto show a lot by accident.
Go to System Preferences > Dock and choose either Left or Right for Position on Screen
inlineAds=true;var isMobile=/iPhone|iPad|iPod|Android/i.test(navigator.userAgent);if(!isMobile){document.write("<script src='//ap.lijit.com/www/delivery/fpi.js?z=332935&width=728&height=90'><\/script>");} else{document.write('<script src="//ap.lijit.com/www/delivery/fpi.js?z=460172&width=320&height=480"><\/script>');}
Tweak Touch Bar
Go to System Preferences > Keyboard > Customize Control Strip, drag the buttons we want to to the Touch Bar below the display, drap tge buttons we don’t want upward and out of the Touch Bar.
Enable Touch ID
Preferences > Touch ID
Then we can use touch id instead of manually type password
Use Touch ID for sudo
vi nano /etc/pam.d/sudo
add “auth sufficient pam_tid.so” to the top
Remove Siri from the Touch Bar
System Preferences > Keyboard > Customize Control Strip
Highlight the Siri button, click, and drag the Siri button upward and out of the Touch Bar
Disable Siri at Preferences -> Siri
Turn off iCloud Drive
Mac backup files in desktip and Documents folder to iCloud, if we never use iCloud(for me, I use Google Drive to backup files), we can turn it off at System Preferences -> iCloud,
Also turn off “Photos” at System Preferences -> iCloud.
Preferences > General
Turn on Dark Mode at System.
Check “Automatically hide and show the menu bar”
Change “Default web browser” to Chrome.
Turn screen corners into shortcuts
Go to System Preferences -> Desktop & Screen Saver -> click on Screen Saver tab -> click on Hot Corner button at the bottom-right.
Add “Put screen into Sleep” to the top right corner: this is useful when we are playing music, but want to put display into sleep right away to save battery.
Install apps downloaded from web:
System Preferences > Security & Privacy -> at General tab, choose App Store and identified developers for Allow apps downloaded from.

Compatible with commands from other OS
If we have scripts that were originated written for MacOS, now we want to run it in another Linux System: for example, Debian. Some commands like “pbcopy and pbpaste” are only available in Mac. We can change the code to detect which command it should use like below:
pb() { if ! type "pbcopy" > /dev/null; then pbcopy else xsel --clipboard --input fi }
Or we can just define alias in .bashrc:
function pbcopy () { xsel --clipboard --input "$@" } function pbpaste () { xsel --clipboard --output "$@" }
UNIX Command Options
# Let there be color in grep! export GREP_OPTIONS=' — color=auto' # Set Atom-Beta as the default editor export EDITOR="atom-beta --wait" # http://bashrcgenerator.com/ # only show current directory export PS1="\w \[$(tput sgr0)\]"

Maximize Finder Window Size with Relaunch
The default Finder window size is way too small.
Keep only one finder window: as when Finder opens a new window, it uses the last accessed window size, if there are multiple windows, it’s hard to tell which one Finder uses as the template.
Adjust the finder window size
If you keep the Dock at the bottom, don’t take the whole bottom of the screen, as it may conflict with the Docker: when we want to click “Path bar” at the bottom, it will accidentally show the Docker.
Or we can move dock to the right side: at System Preference -> Dock, look for Positions on Screen and choose right.
Relaunch Finder
Go to Apple menu -> Force Quit: (or Command+Option+Esc) to kill finder, Mac will relaunch Finder automatically.
or click Alt(Option) key first then right click on the Finder in the docker, then click “Relaunch”
Change Default Finder Window other than default “Recents”
When we open a new finder, it opens “Recents” smart folder, but in most cases, we want to go to some folder, don’t really care about recently added files.
We can change the default folder to our frequently accessed folder at the General pane of Finder -> Preferences: for example the home folder, or the master folder that we hold all our files in work.
inlineAds=true
Search Current Folder instead of “This Mac”
At Preference -> Advanced tab, find “When performing a search:” at the bottom and choose Search the Current Folder.
Customize the sidebar
At Preference -> Sidebar tab, choose what to show and hide in sidebar.
Command+Ctrl+T(or drag) to add frequently accessed folders to the sidebar.
Show Path Bar
Show the Current Path the the bottom: Go to View menu > check Show Path Bar
When we right click on any folder in the path bar, then for any folder, we can Copy xx as Pathname, “Open in new Tab”, “Show in Enclosing Folder”(go to that folder in current tab), “Get info”.
Customize the Toolbar
Go fo Finder -> View -> choose “Customize the toolbar”, we can add “Get info”, “New Folder” buttons.
Quick Look
Select one or more items then press the Space bar, use left, right to go to previous or next.
Press Option key when press space to quick look in full-size.
Hold Option Key while Click
In the right context menu, press Option key would:
- Change “Copy xxx” to “Copy xxx as Pathname” - Change “Open with” to “Always Open with” - Change “Quick Look x items” to “Slideshow x items”
Everything about File or Folder Path on Mac
Check here for how to quickly copy file path or use shortcut to open (parent) folder in iTerm2(or Terminal)
Show Me More Info: Filename Extension and Hidden Files
Check “Show all filename extension” at Advanced tab from Finder’s Preference.
Show hidden files
Run defaults write com.apple.finder AppleShowAllFiles -bool YES && killall Finder at Terminal.
Reveal Files in Finder in Spotlight
When search in Spotlight, use the arrow keys to select file:
- hold Command key(⌘) would show the file path - hold Command key(⌘) while press enter would show the file in Finder
Search, Saved Search(Smart Folder)
During search, we can specify conditions like: kind, file extension, created date, modified date, last opened date, and much more.
We can directly delete files in search result.
We can save the search as smart folder and add them into side bar for easy access.
More Tips for Mac Finder
We can lock a file by right clicking a file -> Get info -> select Locked.
Command+delete to delete files
Actions on multiple files
After select multiple files, we can copy, rename, quick look, slideshow, compress them, put them into new folder.
Cmd-C then Opt-Cmd-V to Cut a File
It only works for files, not folder.
Finder Shortcuts We Should Know
Command + N(T) New Finder Window(tab) Shift + Command + N New folder Command + Delete Move selected item to trash Command + D Duplicate selected files Control + Command + T Add selected item to sidebar Command + O Open selected item Command + Down Arrow In list view, opens the selected folder Command + Up Arrow Go to enclosing folder Command + 1(2,3,4) View as icons(list, column, cover flow) Command + Right(left) Arrow In list view, expands(collapses) the highlighted folder Command + [(]) Go back(forward) to previous location Command+Shift+G Go To Folder

Right click on a file to show the context menu, hold Option(⌥) key, “Copy xxx” will be changed to “Copy xx as Pathname”.
Copy a File or Folder Path at Path Bar
First go to Finder -> open View menu, check “Show Path Bar”, then right click at the path bar at the bottom, choose “Copy xx as Pathname”.

Get File or Folder Path at iTerm2(or Terminal)
If we want to get the file or folder path in Terminal, “Ctrl+C” to copy the file or folder in Finder, then paste it into the Terminal: it will paste the full path (all special characters are already escaped, so no need to add " ").
Go to the Parent Folder (of a File or Folder) at Iterm2(or Terminal)
To go to the parent folder of a folder or especially for a file:
First let’s define the following pcd command in ~/.bash_profile which will go to the parent folder of the file; then source ~/.bash_profile
function pcd () { cd "$(dirname "$1")" ; pwd; }
Then “Ctrl+C” at the selected file in Finder, then in Terminal type pcd, space, then paste the file.
“New iTerm2 Tab” in Finder
I use iTerm2 as my default Terminal, but the approaches for iTerm2 would also work for the default Terminal.
After select a file, choose New iTerm2 Tab in the context menu, it will create a new tab and cd to the enclosing folder.
After select a folder, choose “Services - > New iTerm2 Tab”.
Assign Keyboard Shortcut to “New iTerm2 Tab” at Finder
Go to System “Preferences -> Keyboard -> Shortcuts”, choose “Services” in the left panel, find “New iTerm2 Tab” and assign a shortcut like: Ctrl+Option+i.
To check whether the shortcut assignment works, we can go to Finder menu, Finder -> Services, check whether the new shortcut is shown for the “New iTerm2 Tab” menu item.
If the shortcut is not there and doesn’t work, it’s often because the shortcut we choose conflicts with other existing shortcuts.
Now we can Ctrl+Option+i to open a new tab for any file at Finder.

is:trashed - find files in trash folder
Search by Owner
find files owned by this user: type user’s email first(Google Drive can auto autocomplete the gmail name), then add “owner:” prefix.

Manage Storage: Use Less Space to Store More Files
Open settings(shortcut: t), click the View items taking up storage to find out what files are using most spaces.
or access drive.google.com/drive/quota directly
Caveat: the files in trash would not shown in the here.
Delete Files from Trash Folder
When we delete a file in Google Drive, it will be put into trash folder and thus still take your space.
When you are out of space, you can try to delete files from trash or empty trash folder. Be sure to know what you you are doing, as if we delete them from trash folder, they would be gone forever.
Check Whether a File Use Storage or Not
Google Drive may or may not use storage limit for files like videos: if we backup them with high quality option, it will not use storage.
To check whether a file uses storage or not, open the details vide by shortcut: ‘d’ or click More Actions at the top menu bar and choose View Details,
Backup Files using Backup and Sync App with High Quality
If you don’t mind the reduced quality, when backup, choose “High Quality” for Free unlimited storage for videos and photos.
This “High Quality” option only works for backup, NOT sync: it means videos, photos you synced using the App would still use original quality and thus use storage.
Files you upload to drive would still use original format, thus use storage limit. Don’t upload big video or images files directly using the web to drive, use the Backup and Sync App
To keep files with original quality, we can zip these files and store them into another Google drive account.
We can add the files in backup to other folders: go to Computers side bar in Drive, choose the file then click Add to My Drive in the context menu.
Transfer Files to Others
Files that shared with you would not count as against your quota. You can transfer these big files into another account.
We can only transfer ownership of Google files like Google Docs/Sheets/Slides etc.
To transfer videos to another account
Share the file with another account
Collaborator makes a copy of the file and share it with the original account
In the original account, delete the original file permanently and move the shared file into appropriate folder.
Sync folders using Backup and Sync App
We can specify what Folders in Google Drive would be synced to local laptop.
Organize Files/Folders
Raw Files in Root Folder
Be aware that files(like pdf, videos) including those created in future in the root(/) folder would be also synced into local laptop.
Google should improve this
Google should improve this: as usually we save files into root folder, then we move it to right folder. But Google Drive already synced files to local laptop then delete it locally. Kind of waste computation resource.
For example when we save to Google drive at the print dialog, we can’t set the destination folder. Though we can change the file name at the advanced settings.
Google Drive can fix this by simply create a default “GoogleDriveDownload” folders, all files are stored in this folders by default.
Put files into right folders
Be sure to rename the file to a better name and put it into right folder.
We may not be able to put files in the right folder when we are saving it to Google Drive for example during print. But be sure to go to Drive to rename and move it: the newly added files will be shown at Quick Access section or check the recent tab at right side.

Embed Images from Google Drive into Website
Get a shareable link from the image in Google drive and replace the id https://drive.google.com/uc?export=view&id={fileId}
This link seems to be subject to quotas. So not ideal for public/massive sharing.
