MacOS¶
The best overall desktop OS even when compared to Linux + KDE.
shortcuts¶
Some keyboard shortcuts can be changed, some can't (or are a bit complicated to change). Go to Settings -> Keyboard -> Shortcuts to view the changeable ones.
command+Q¶
Command + Q is an unchangeable shortcut key which will close an application. You can't remove it, but you can remap it to harmless stuffs (like Show Notification Center).
https://apple.stackexchange.com/questions/78948/
Minimize shortcut¶
The unchangeable shortcut for minimizing a window is CMD+M. To disable it
- System Preferences > Keyboard > Shortcuts > App Shortcuts
- Add a shortcut with title =
Minimizemapping to an obscure shortcut - Close the settings window for it to take effect
Active apps also need to be reopened otherwise pressing CMD+M on them will still minimize them.
See https://apple.stackexchange.com/a/125628
Or you can reassign CMD+M to another shortcut.
Reassign system shortcuts¶
See Locking your Mac with Command+L

Prevent sleep when lid closed - Amphetamine¶
M2
It does not work
Before M2
There is no native way to do this (unless you're connected to an external monitor). Have to install 3rd party app.
- Install Amphetamine on App Store.
- Install Amphetamine Enhancer from Github
- Setup Amphetamine Enhancer
- Click Amphetamine's icon on the menu bar
- Quick Preferences -> uncheck "Allow system sleep when display is closed"
- Start New Session -> "Indefinitely"
- Preferences -> General -> check all boxes under "Launch and Wake behavior"
- That's it
- you can still make your computer sleep in the normal way
Only show relevant menubar items¶
Use Bartender. It's not free but after the free trial it only pops up to tell you to buy it from time to time while still letting you access full features, like WinRAR.
You can also try Dozer
Dozer will giver you 2 dots on the menubar. Drag relevant menubar items to the right of the leftmost dot and press it, now all the other items will be gone. Click again and they will reappear.
Show ethernet status in menubar¶
Use https://apps.apple.com/us/app/ethernet-status-missing-lan/id1186187538
Troubleshooting¶
Show hidden files in Finder¶
Some settings do not take effect¶
Close and reopen the app if the new settings aren't working on an app.
Stop desktop order from changing itself¶
System Preferences > Mission Control -> uncheck "Automatically rearrange Spaces based on most recent use"
https://apple.stackexchange.com/a/214349
Stop apps pinning itself on dock¶
System Preferences -> Dock & Menu Bar -> Uncheck "Show recent applications in Dock"
https://apple.stackexchange.com/a/338004
make dock appears on another display¶
When you're using more than one display, you can only make the dock appears on one of them. To make the dock appears on another display:
hide the dock (use the shortcut listed in system preferences -> keyboard -> shortcuts) -> go to another display -> keeps moving your cursor down (bottom screen edge) until the dock appears
use the normal fullscreen in firefox¶
When you press f11, the tabs and bookbar bar are still there. To hide them, (when you're still in "fullscreen") right click on the hamburgar menu -> "Hide Toolbars".
To return to the default retarded MacOS behavior, create a new tab (with your hotkey or whatever) to make the tab bar appear, and then right click on the hamburgar menu -> unselect "Hide Toolbars".
Note that the fullscreen after you hide the toolbars is still not the same as it is on Windows & Linux. When your cursor move to the top of the screen, only the bookmark bar & the main bar are show, while the tab bar still remains hidden.
Two Finger Pinch Zoom Unreliable¶
sol1: spread wide open on trackpad (doesn't work)
https://discussions.apple.com/thread/253369850
sol2:
No xxx in spotlight result¶
See https://support.apple.com/en-us/HT201716
- Locate the directory the missing thing is in, e.g.
simulator.appis from/Applications/Xcode.app/Contents/Developer/Applications. - Go to System Preferences -> Spotlight -> Privacy
- Drag the directory into it (so the directory will not be indexed)
- Remove it (so the directory will be indexed again)
- Quit System Preferences
- Now it should work

Press with a finger not registered for TouchID

Some menubar items hidden¶
If your screen have a notch and have a ton of items in the menubar, many will get hidden. Only (free) solution is to command+drag to drag the unimportant ones out to make space for relevant ones.
If you want to pay, Bartender seems to be a solution.

Area under notch is not used even if "Scale to fit below built-in camera" option is not checked¶
Reboot
Can't connect to ASUS monitor¶
Problem
My Asus monitor will oscillate between connected and not connected when connecting to my MacBook Pro 14" M2 Pro 2023.
Solution
First install DisplayLink Manager if you haven't. You can find the files you need to download in ASUS's download page.
Next, go to System settings -> Displays -> set "Refresh rate" to 60Hz
It works for me in Macbook Pros with Intel chips but not M2. For M2, I tried a few type C to type C cables and only one of them can make the connection work consistently.
Chinese input laggy¶
Kill the process and reopen your app if it's still laggy on an app.
