Apple released a minor update on December 16, 2003 that brought ARD to 1.2.4. This update concentrated on security, performance and reliability. On June 21, 2004 Apple announced Apple Remote Desktop 2 (released in July), which was designed to use the VNC protocol (with many private extensions) instead of Apple's original ARD protocol.

Apple Remote Desktop (ARD) is a Macintosh application produced by Apple Inc., first released on March 14, 2002, that replaced a similar product called Apple Network Assistant.^[1] Aimed at computer administrators responsible for large numbers of computers and teachers who need to assist individuals or perform group demonstrations, Apple Remote Desktop allows users to remotely control or monitor other computers over a network.

Apple fixed the vulnerability in Big Sur 11.2.1, Catalina 10.15.7 and Mojave 10.14.6, but did not fix High Sierra and dropped support for that version. Software vendors have quickly followed suit and no longer support products on High Sierra which includes Microsoft Office 365 and Adobe CC 2021.

Releases[edit]

The original release, which used the User Datagram Protocol (UDP) on port 3283, allowed remote computers (running Mac OS 8.1 or later) to be observed or controlled from a computer running macOS. It also allowed remote computers to be restarted or shutdown, to have their screens locked or unlocked, or be put to sleep or awakened, all remotely. Version 1 also included simple file transfer abilities that would allow administrators to install simple applications remotely, however to install applications that required the use of an installer the administrator would have to run the installer manually through the client system's interface.

Version 1.1 (released August 20, 2002) introduced the ability to schedule remote tasks.

Version 1.2 (released April 2, 2003) added a number of features that were designed to ease the administration of a large number of computers. Software could now be installed remotely on a number of machines simultaneously, without using the client system's interface. The startup disk on remote computers can also be changed, setting them to boot from a NetBoot server, a Network Install image, or a partition on their own drives. The client ARD software could also now be upgraded remotely to allow administrators to take advantage of new features without having to visit each individual computer.

Apple released a minor update on December 16, 2003 that brought ARD to 1.2.4. This update concentrated on security, performance and reliability.

On June 21, 2004 Apple announced Apple Remote Desktop 2 (released in July), which was designed to use the VNC protocol (with many private extensions) instead of Apple's original ARD protocol. This allows the ARD administration software to observe and control any computer running VNC-compatible server software (such as Windows and Unix systems) not just Macs and conversely allowing standard VNC viewing software to connect to any Mac with the ARD 2 software installed and VNC access enabled. This version also uses the Transmission Control Protocol (TCP) for most functions (on ports 5900 and 5988), which is designed to be more reliable than the UDP used in ARD 1.^[2] Another significant addition to ARD 2 was the Task List, that allows remote tasks to be queued and monitored, reporting their status (such as Succeeded or Failed). This release also dropped support for older versions of the Mac OS, requiring 10.2.8 or higher.

On October 11, 2004 Apple released version 2.1 which improved on a number of existing features while adding the ability to view observed or controlled computers in full screen, the ability to see the displays of computers with more than one monitor and support for mouse right-click and scroll-wheels.^[3]

On April 29, 2005 Apple released version 2.2 which added support for Mac OS X 10.4 along with several other bug-fixes and improvements to reliability.^[4]

On April 11, 2006 Apple released version 3.0 which is now a Universal Binary and features improved software upgrade functionality, Spotlight searching, as well as increased throughput and encryption for file transfers, and Automator support.

On November 16, 2006 Apple released version 3.1 which provides support for the new Intel-based Xserve Lights Out Management feature.

On October 18, 2007 Apple released version 3.2 which introduced Mac OS X 10.5 support and compatibility for third party VNC viewers and servers.

On August 20, 2009 Apple released version 3.3 which fixed many bugs and allowed function keys and key combinations to be sent to the remote computer instead of the local machine.^[5]

On January 6, 2011 Apple released version 3.4 which provides compatibility with the Mac App Store.^[6]

On July 20, 2011 Apple released version 3.5 which provides compatibility with Mac OS X 10.7.^[7]

On October 22, 2013 Apple released version 3.7 which provides compatibility with OS X 10.9, multiple monitors, and enhancements to remote copy/paste.^[8]

On January 27, 2015 Apple released version 3.8, which primarily added support for OS X 10.10, while also including various user interface improvements, a new icon, stability improvements and the ability to update the application using the Mac App Store, even if the application was not originally installed from that source. This version now requires OS X 10.9 or above.^[9]

On February 21, 2017, Apple released version 3.9, which heightened communications security between local and remote computers (including a Preferences checkbox to allow communication with pre-3.9 clients), added support for the MacBook Pro TouchBar, addressed various stability issues, allowed the user to export and import an encrypted list of computers with user credentials, and debuted the ability to use an 'Assistance Cursor' to call attention to items for the remote user. This version now requires OS X/macOS 10.10.5 or later.^[10]

Encryption[edit]

Prior to version 3, ARD encrypted only passwords, mouse events and keystrokes; and not desktop graphics or file transfers. Apple therefore recommended that ARD traffic crossing a public network should be tunnelled through a VPN, to avoid the possibility of someone eavesdropping on ARD sessions.^[11]

ARD 3.0 has the option of using AES 128 bit, the same as a basic SSH server.

ARD 3.9 included as yet unspecified enhancements to communications security that made the native mode incompatible with previous-version clients. A Preferences checkbox was provided in the Apple Remote Desktop app to explicitly allow communications with older clients. ARD 3.9.2 made the use of this checkbox optional for seeing clients in the list.^[10]

Legal[edit]

In November 2017, the United States International Trade Commission announced an investigation into allegations of patent infringement with regard to Apple's remote desktop technology. Aqua Connect, a company that builds remote desktop software, has claimed that Apple infringed on two of its patents. ^[12]

Restrictions[edit]

ARD does not support reverse connections to listening VNC viewers.^{[citation needed]}

24 Apr How to Upgrade Mac to macOS High Sierra

April 24, 2018

The latest version of the macOS operating system, macOS High Sierra, was released on Monday, September 25, 2017.

In this article, we will explain how to upgrade mac to macOS High Sierra.

Why Should We Upgrade to macOS High Sierra?

Apple released the latest macOS, High Sierra, and added some new features including a new and improved Apple File System (AFPS), a faster browser, stellar graphics, better gaming capabilities and VR support. MacOS 10.13 is absolutely worthwhile to upgrade your Mac.

macOS High Sierra System Compatibility

You can download and install macOS High Sierra OS for free in 2009 or later. Basically, if your Mac is currently running macOS Sierra system (macOS 10.12), you can smoothly upgrade to macOS High Sierra.

The following is the device compatibility information released by Apple:

• iMac (Late 2009 or newer)
• MacBook Air (Late 2010 or newer)
• MacBook (Late 2009 or newer)
• Mac mini (Mid 2010 or newer)
• MacBook Pro (Mid 2010 or newer)
• Mac Pro (Mid 2010 or newer)

Some features, such as High Efficiency Video Coding (HEVC) encoding and decoding require newer processors and devices, some of which unfortunately cannot run on older devices.

If you are running OS X Lion (10.7.5) or later, you can upgrade directly to macOS High Sierra.

How to Upgrade macOS

There are two ways to upgrade macOS: directly in Mac App Store, or upgrade using an USB device.

Apple Upgrade From High Sierra To Catalina

No matter which way you choose, always remember to back up your data before performing an upgrade.

Time Machine Backup

Apple has its own official backup tool: Time Machine. This feature was released in OS X 10.5 Leopard. If you have never backed up, let me tell you how important it is.

Time Machine can connect to your Mac and any external hard drive via USB, FireWire or Thunderbolt port. Back up everything on your Mac directly to your hard drive, in case the Mac cannot upgrade properly.

It also supports Apple’s Time Capsule and backup disks connected over a network as long as the disks support AFPS. As long as the disk is available to your Mac, you can use it for Time Machine backups.

When enabled, Apple’s Time Machine will periodically transfer all files and store data on an inserted external hard drive or on a Time Capsule connected to the network.

You can choose hourly, daily or weekly backup to store your data on the external hard drive. When the external device is full, Time Machine will delete the oldest backup and replace it with the newer version.

Let’s check how to enable Time Machine backup on Mac devices.

1. Choose “System Preferences…” from the Mac menu.

2. Double-click the Time Machine icon.

Apple Upgrade To High Sierra

3. Click “Select Backup Disk…” to select the disk you want to use as a Time Machine backup.

4. Select the “Back Up Automatically” check box so that your Mac will automatically back up data to your chosen disk.

If you want to restore files from Time Machine, make sure your Mac is running. Click “Enter Time Machine”, find the previous file or folder, and then click “Restore.”

Besides Time Machine, you can try other great backup and restore software such as Carbon Copy Cloner (CCC) and SuperDuper.

1. Direct Upgrade in Mac App Store

Generally, you can upgrade your system directly in the Mac App Store by clicking “Check for Updates” or click the following link to download macOS High Sierra:

https://itunes.apple.com/app/macos-high-sierra/id1246284741?l=en&mt=12

If you use a Beta version, you still need to click the link above to download the system, or go to the developer’s website for download information.

If you want to choose “USB clean upgrade”, check the detailed information below.

2. Upgrade using USB device

i. USB Preparation

Before formatting your current operating system, download macOS High Sierra from the Mac App Store first. You will need a copy of macOS High Sierra to perform a clean installation later. If you want to upgrade to this version, it is possible as long as your current operating system version is lower than macOS High Sierra.

Natively, look for “Disk Utility” in your application, select an external USB device with a capacity of 8 GB or larger, format it directly, and remember to choose the format “Mac OS Extended (Journaled)”. If it is a hard disk, it would be better to make a partition beforehand.

If you have already downloaded the macOS High Sierra package, do not click on the installation. Directly open the “terminal” program, which you can find in the application.

When typing the following text in the terminal, check the name of the formatted external USB device. If you do not name it “Untitled”, you need to change the command syntax of the path name: Volumes/Untitled. The names of external USB devices cannot contain spaces and are case sensitive.

sudo /Applications/Install macOS High Sierra.app/Contents/Resources/createinstallmedia –volume /Volumes/Untitled –applicationpath /Applications/Install macOS High Sierra.app –nointeraction

Press “Enter” on your keyboard to execute the command. You will then be prompted to enter the administrator password. It will start the process after the operation, which can take a long time, depending on the transfer speed of the external USB device. When done, the terminal window will report “Done.”

ii. USB Upgrade Installation

a. Click the Apple icon .

b. Choose “Restart…” from the drop-down menu.

c. Press and hold “Command+R” when you hear a startup ring (or when the screen on your newer Mac device turns black), and hold down the keys until your computer restarts.

d. Open “Disk Utility”, choose your startup disk, and then click “Erase”.

e. Select “Mac OS Extended (Journaled)” from the list of volume formats and start formatting.

f. When it returns to the former page, insert your USB and click “Continue”.

g. When the installation window appears, click “Continue” again.

h. Agree to the software terms and conditions. Choose your hard drive.

i. Click “Install” and wait until the upgrade is done

How to Keep Your Mac Always Clean

If you have done a complete installation of macOS, you must be enjoying the completely new macOS now. I believe you also want to keep your Mac clean. Let’s say someday your Mac has a lot of junk files and duplicate photos. There are also probably many apps you have never used and don’t need them anymore. I must tell you there is a savior for your Mac! Its name is Cleaner One. It’s really great to have such a system optimizing tool. With its “Junk Files” feature, it not only cleans temporary files including logs, mail caches, iTunes and iOS temporary files, and empties trash for the current user, but also detects remaining files after deleting apps.

It also has a function called “Duplicate Files”, which can find duplicate files on your Mac through fast and accurate scanning techniques covering your entire home folder. Duplicates are selected not only by the file name but also by their contents. Files are shown in detailed previews. It can further help you decide which copy to delete by presenting the “Auto Select” button.

Duplicates can be sorted by file type and listed in their full route for you to track. You can decide which way to clean these files; either by sending them to trash or deleting them permanently.

You probably also need an intelligent app uninstaller. Don’t worry, Cleaner One has this function. It can auto-clean leftovers of deleted apps and manage all the applications installed on your Mac easily. When you remove an app you don’t need anymore, it can get rid of all the associated files of the uninstalled app as well. It will also notify you of new updates to installed apps.
