Screen Sharing is a feature that allows you to view and control the screen of another Mac on your network.
However, Screen Sharing cannot be turned on if Remote Management is already enabled on your Mac.
Remote Management is a more advanced feature that allows you to remotely manage Mac computers in a commercial or business environment. Remote Management and Screen Sharing are compatible with Virtual Network Computing (VNC), but they cannot be used at the same time. To turn on Screen Sharing, you need to turn off Remote Management first in the Sharing settings of System Settings. The other sharing settings, such as Remote Login, Media Sharing, and Remote Apple Events, do not affect Screen Sharing and can be turned on or off independently.

Activities is a feature in Console that allows you to view log messages grouped by the activity they are associated with. This helps you focus on specific log messages and allows for a more complete analysis of your Mac. To view activities in Console, you need to click the Activities button in the toolbar (or use the Touch Bar). If the Activities button is dimmed, you need to click Start in the toolbar first. You can then select an activity to see the log messages for that activity, expand or collapse child activities, and view the details of an activity.

Sysdiagnose log files are located on iPhone in Settings > Privacy & Security > Analytics & Improvements >
Analytics Data. Sysdiagnose is a tool that collects information from the iPhone and saves it in a log file.
You can use sysdiagnose to troubleshoot general iOS issues or report them to AppleCare. To generate a sysdiagnose log file, you need to press and hold both volume buttons and the side or top button for 1 to 1.5 seconds, then release them. You will see a screenshot and a message that says "Diagnostics are in flight".
Sysdiagnose can take up to 10 minutes to finish. After that, you can find the log file in the Analytics Data section of the Settings app. The log file name will start with "sysdiagnose_" and include the date and time of the generation, the device type, and the iOS version. For example, "sysdiagnose_2024.01.06_17-14- 34
+0500_iPhone_OS_iPhone_19A344.tar.gz".

In the Notes app, you can lock notes to protect your sensitive information. You can access your locked notes using your device passcode or a custom password. If you have multiple Notes accounts, you choose the locking method for each account (for example, your iCloud account). You can also use Face ID or Touch ID to access your locked notes, if you enable this option in the settings. To lock notes with a custom password, you need to go to Settings > Notes > Password, choose an account, and tap Use Custom
Password. To lock notes with Face ID, you need to go to Settings > Notes > Password, choose an account, and turn on Face ID. To lock or unlock a note, you need to tap the More button and then tap the Lock icon. You can also lock or unlock all notes in the Notes app by tapping the Lock icon in the bottom

toolbar.

Some universal apps (apps that don't need Rosetta) include the setting "Open using Rosetta." This setting enables a universal app such as a web browser to use plug-ins, extensions, or other add-ons that do need Rosetta, because they haven't been updated to support Apple silicon. If a universal app doesn't recognize an add-on that you installed for the app, you can quit the app, select this setting, and try again. To do this, you need to open the app's Get Info window and check the box labeled "Open using Rosetta".
