The terminal command defaults write com.apple.finder ShowMountedServersOnDesktop true sets the Finder preference to show mounted servers on the desktop. This is equivalent to checking the box for "Connected Servers" in the Finder settings under the General tab. The other commands are either invalid or do not change the preference value.
* defaults read com.apple.finder ShowMountedServersOnDesktop true reads the current value of the preference, but does not modify it.
* defaults cat com.apple.finder ShowMountedServersOnDesktop true is not a valid command, as cat is not a valid subcommand for defaults.
* defaults append ShowMountedServersOnDesktop com.apple.finder true appends the value true to the preference key ShowMountedServersOnDesktop, which is not a valid operation, as the preference value should be a boolean, not a list. References:

Activity Monitor is an app that shows information about the processes running on your Mac, including how much CPU, memory, disk, network, and energy they use. You can use Activity Monitor to identify and quit processes that are slowing down your Mac or causing other issues. You can also view graphs and statistics of your Mac's performance and activity. To open Activity Monitor, go to Applications > Utilities, or use Spotlight to search for it. You can then select a process and click the Info button to see more details, or click the X button to quit the process. You can also sort the processes by different columns, such as CPU, Memory, or Energy, to see which ones are using the most resources. You can also choose different tabs to see different types of processes, such as CPU, Memory, Disk, Network, or Cache. Activity Monitor is a useful tool for troubleshooting performance issues on your Mac and optimizing its efficiency.

Your Mac uses Bluetooth to broadcast its location information after you turn on Find My when it's offline or in sleep mode. This is part of the Find My network, which is an encrypted, anonymous network of hundreds of millions of Apple devices that can help you locate your device, even when it's offline1. When your Mac is offline or in sleep mode, it sends out a secure Bluetooth signal that can be detected by other Apple devices nearby. These devices relay the location of your Mac to iCloud so you can view it in the Find My app2. The other options, Ultra Wideband (UWB), Emergency SOS, and Wi-Fi, are not used by your Mac to broadcast its location information in this scenario.

If you forgot your passcode and your iPhone is disabled, you need to erase your iPhone and set it up again.
The only way to do this is to put your iPhone in recovery mode and connect it to a computer with iTunes or Finder. This will erase all your data and settings, including the passcode, and install the latest version of iOS or iPadOS on your iPhone. You can then restore your data and settings from a backup, if you have one, or set up your iPhone as a new device. To put your iPhone in recovery mode, you need to follow these steps:
* Make sure that your iPhone is not connected to your computer, then turn it off completely.
* Press and hold the correct button for your iPhone model while connecting it to your computer. For iPhone 8 and later, use the side button. For iPhone 7 and 7 Plus, use the volume down button. For iPhone 6s and earlier, use the home button.
* Keep holding the button until you see the recovery mode screen on your iPhone, then release the button.
The recovery mode screen shows a cable and a computer icon.
* On your computer, open iTunes or Finder and locate your iPhone. You should see a message that says there is a problem with your iPhone that requires it to be updated or restored.
* Choose Restore to erase your iPhone and install the latest software. This may take some time, so do not disconnect your iPhone until the process is complete.
* After your iPhone is restored, you can set it up again using the onscreen instructions. You can choose to restore from a backup or set up as a new device.
