Time Machine is the built-in backup feature for macOS that allows users to back up their system automatically. It continuously backs up everything on the Mac, including files, applications, system files, and settings, allowing users to restore their system to a previous state if needed. Time Machine operates by creating hourly backups for the past 24 hours, daily backups for the past month, and weekly backups for all previous months. Other options like 'Mission Control' help in organizing windows, while 'System Restore' is a feature more common in Windows operating systems, not macOS.

The first step in securing a newly installed SOHO (Small Office/Home Office) wireless router is to ensure it has the latest firmware installed. Firmware updates often include important security patches and new features that protect the router from known vulnerabilities. Other actions, like disabling unused ports or guest accounts, can be useful for hardening the security, but they should come after the router is running the most recent and secure version of its firmware.

Time drift occurs when the internal clock of a computer is not properly synchronized, often leading to discrepancies like being an hour behind. In this case, the workstation is the only device affected, indicating that it's likely a local issue. Time drift can happen if the system clock isn't syncing properly with an NTP (Network Time Protocol) server or if automatic daylight savings adjustments aren't enabled. It's less likely to be a CMOS battery issue since the technician has already verified the correct date and the system clock isn't completely reset (which is what happens when the CMOS battery fails).

A checksum is a cryptographic hash function (like MD5 or SHA-256) used to verify the integrity of files. When downloading files from the internet, websites often provide the checksum value of the file so that users can ensure the file was not altered during download or corrupted. The user can generate the checksum on their local system and compare it to the one provided by the site. If they match, the file is intact and safe to use. Other options like BitLocker or FileVault are encryption tools, and a password manager is irrelevant to file verification.

In macOS, the 'Privacy' settings under 'Security & Privacy' are where users can control which applications are allowed to run, including third-party apps. By default, macOS may restrict apps that are not downloaded from the App Store, but in the Privacy settings, users can enable installations from identified developers or even from any source. The other options like 'Keychain' manage passwords and certificates, 'Accessibility' deals with assistive technologies, and 'Spotlight' is the search feature.

The most likely reason for the installation failure of a 64-bit software is that the operating system is incompatible, specifically if the system is running a 32-bit version of the OS. A 64-bit program requires a 64-bit operating system to run, and if the user's OS is a 32-bit version, the software will fail to install. Other reasons, like needing administrator privileges or updating .NET, are valid but less likely since the error message would be different.

Windows 10 is natively compatible with Active Directory. Active Directory is a Windows-based directory service that manages domain-based networks. It allows for centralized management of users, groups, and resources, which is a key feature in enterprise environments using Windows OS, such as Windows 10. Other operating systems like macOS, Linux, and Chrome OS may require additional software or configurations to interact with Active Directory, but they do not natively support it.

To configure a new SSD, the technician would use diskmgmt.msc (Disk Management) and diskpart.msc (Diskpart). These tools allow for partitioning, formatting, and managing the SSD. Disk Management is a graphical utility that provides easy access to these tasks, while Diskpart is a command-line tool with advanced features for disk configuration.

Diskmgmt.msc: A GUI-based tool used to manage disk partitions.

Diskpart.msc: A command-line utility used for advanced disk configuration.

The user should configure extensions/add-ins. Since the issue involves a browser plug-in, checking if the extension or add-in is enabled or properly configured can resolve the issue. If the plug-in is disabled, the OTP prompt will not appear as expected.
