Share Media For Mac

admin 12/11/2021

Media sharing, or streaming, is normally disabled for Windows 10 laptops. To activate the feature and make your laptop’s music, pictures, and video available to other computers on a private network, follow these steps: Open the Control Panel. Press the Win+X keyboard shortcut and choose Control Panel from the supersecret menu. Beneath the Network and. 2 days ago  Share All sharing options for. Mac gamers should know that they, too, need the real estate and the bandwidth to choke down a 150 GB download. Here are some ways to make it easy to reconnect to shared computers and servers you frequently use: On your Mac, do any of the following: Choose Apple menu Recent Items, then choose from the list of recent servers. In the Finder, choose Go Connect to Server, click the pop-up menu to the far right of the Server Address field, then choose a recent server.

A share menu plays a vital role in any operating system. If it’s broken or inconsistent (Hey Android, looking at you), then it takes away the experience of using the device. After all, the Share menu is one of your most-used interfaces on mobile and desktop. As for macOS, Apple offers a standard Share menu to send stuff. It also lets you customize the share menu based on your preference and needs.

Some may wonder why anyone would need to edit the Share menu on Mac? Well, using a custom share menu across the OS, you can make sure that you enjoy a consistent sharing experience. And unlike iOS, Apple is flexible in letting you modify such details on Mac.

In this post, we will explain how to edit the share menu on Mac, how it works on different apps, and how to add third-party apps on the share menu on Mac. Let’s get started.

Edit Share Menu on Mac

The standard share menu on Mac comes with first-party apps integration such as Reminders, Apple Notes, Mail, and Airdrop. But if you are like me and using Mail, Reminders, Apple Notes alternatives on Mac, then the default options won’t work for you.

In such cases, you need to lower down the default options from the sharing menu and put your preferred ones at the top. Follow the steps below to make changes.

Step 1: Tap on the Apple logo at the upper left corner.

Step 2: Go to System Preferences.

Step 3: Navigate to Extensions.

Step 4: Scroll to Share Menu, and you will see all the relevant options on the right side.

Step 5: Disable the ones that you no longer need. You can also use drag and drop to move your preferable sharing extensions at the top.

From now on, whenever you try to share a file on Mac, you will see your custom share menu.

Any change you make to this menu is applied right away, and it’s applied for all files. Normally, the share menu will only show you relevant options that apply to a file. For example, the Add to Reading List option won’t appear when you right-click on an image, so you don’t have to worry about the share menu being crowded.

The options that appear on the Extensions preference are for apps that support the share menu on macOS. If an app doesn’t support the share menu, you cannot force it to appear in this list. You will need to request the developer to consider adding macOS share menu support in the future update.

As for the stock apps and their sharing options, there’s no way to force them out either. They’re all mostly apps that you cannot uninstall from macOS, e.g., the Messages app, so they will appear in the share menu, whether you like it or not.

Open Finder and select any file. Right-click on it and select Share. Scroll down to More, and it will directly open the Share extension menu in the system preferences.

I Don’t See Third-Party App in Share Menu

You can’t access social media apps from the share menu on Mac. However, you can easily place note-taking apps in the sharing menu. If you don't see them in the Share extension screen, follow the trick below to add OneNote and Evernote's likes to the sharing list.

Step 1: Tap on the Apple logo at the upper left corner.

Step 2: Go to System Preferences.


Step 3: Navigate to Extensions > Added Extensions.

Step 4:
Enable Share Menu extension for third-party apps.

You will now see them in the Share Extension menu and easily access the preferred app from the Share menu.

Limitations With the Current Share Menu

The macOS share menu used to be a flexible solution and a central hub for all social network sharing needs such as Facebook, Twitter, and LinkedIn. However, starting with macOS Mojave, Apple has put brakes on social integration in the share menu.

The company states security reasons behind the decision to limit social apps from the macOS share menu. As of macOS Mojave and newer OS, Apple has stripped out Facebook and Twitter integration entirely. Even if you install Tweetbot or Tweetdeck (from the App Store), you still won't find entries for those official apps. So how do you easily share with your social networks?

You will have to go to the usual route to share stuff from Mac File manager to social media. Open the app and go to the compose option. Add media from the following menu.

In IEEE 802 LAN/MAN standards, the medium access control (MAC, also called media access control) sublayer is the layer that controls the hardware responsible for interaction with the wired, optical or wireless transmission medium. The MAC sublayer and the logical link control (LLC) sublayer together make up the data link layer. Within the data link layer, the LLC provides flow control and multiplexing for the logical link (i.e. EtherType, 802.1Q VLAN tag etc), while the MAC provides flow control and multiplexing for the transmission medium.

These two sublayers together correspond to layer 2 of the OSI model. For compatibility reasons, LLC is optional for implementations of IEEE 802.3 (the frames are then 'raw'), but compulsory for implementations of other IEEE 802 physical layer standards. Within the hierarchy of the OSI model and IEEE 802 standards, the MAC sublayer provides a control abstraction of the physical layer such that the complexities of physical link control are invisible to the LLC and upper layers of the network stack. Thus any LLC sublayer (and higher layers) may be used with any MAC. In turn, the medium access control block is formally connected to the PHY via a media-independent interface. Although the MAC block is today typically integrated with the PHY within the same device package, historically any MAC could be used with any PHY, independent of the transmission medium.

When sending data to another device on the network, the MAC sublayer encapsulates higher-level frames into frames appropriate for the transmission medium (i.e. the MAC adds a syncword preamble and also padding if necessary), adds a frame check sequence to identify transmission errors, and then forwards the data to the physical layer as soon as the appropriate channel access method permits it. For topologies with a collision domain (bus, ring, mesh, point-to-multipoint topologies), controlling when data is sent and when to wait is necessary to avoid collisions. Additionally, the MAC is also responsible for compensating for collisions by initiating retransmission if a jam signal is detected. When receiving data from the physical layer, the MAC block ensures data integrity by verifying the sender's frame check sequences, and strips off the sender's preamble and padding before passing the data up to the higher layers.

Functions performed in the MAC sublayer[edit]

According to IEEE Std 802-2001 section 6.2.3 'MAC sublayer', the primary functions performed by the MAC layer are:[1]

  • Frame delimiting and recognition
  • Addressing of destination stations (both as individual stations and as groups of stations)
  • Conveyance of source-station addressing information
  • Transparent data transfer of LLC PDUs, or of equivalent information in the Ethernet sublayer
  • Protection against errors, generally by means of generating and checking frame check sequences
  • Control of access to the physical transmission medium

In the case of Ethernet, according to 802.3-2002 section 4.1.4, the functions required of a MAC are:[2]

  • receive/transmit normal frames
  • half-duplex retransmission and backoff functions
  • append/check FCS (frame check sequence)
  • interframe gap enforcement
  • discard malformed frames
  • prepend(tx)/remove(rx) preamble, SFD (start frame delimiter), and padding
  • half-duplex compatibility: append(tx)/remove(rx) MAC address

Addressing mechanism[edit]

The local network addresses used in IEEE 802 networks and FDDI networks are called media access control addresses; they are based on the addressing scheme that was used in early Ethernet implementations. A MAC address is intended as a unique serial number. MAC addresses are typically assigned to network interface hardware at the time of manufacture. The most significant part of the address identifies the manufacturer, who assigns the remainder of the address, thus provide a potentially unique address. This makes it possible for frames to be delivered on a network link that interconnects hosts by some combination of repeaters, hubs, bridges and switches, but not by network layerrouters. Thus, for example, when an IP packet reaches its destination (sub)network, the destination IP address (a layer 3 or network layer concept) is resolved with the Address Resolution Protocol for IPv4, or by Neighbor Discovery Protocol (IPv6) into the MAC address (a layer 2 concept) of the destination host.

Examples of physical networks are Ethernet networks and Wi-Fi networks, both of which are IEEE 802 networks and use IEEE 802 48-bit MAC addresses.

A MAC layer is not required in full-duplexpoint-to-point communication, but address fields are included in some point-to-point protocols for compatibility reasons.

Channel access control mechanism[edit]

The channel access control mechanisms provided by the MAC layer are also known as a multiple access method. This makes it possible for several stations connected to the same physical medium to share it. Examples of shared physical media are bus networks, ring networks, hub networks, wireless networks and half-duplex point-to-point links. The multiple access method may detect or avoid data packet collisions if a packet mode contention based channel access method is used, or reserve resources to establish a logical channel if a circuit-switched or channelization-based channel access method is used. The channel access control mechanism relies on a physical layer multiplex scheme.

The most widespread multiple access method is the contention-based CSMA/CD used in Ethernet networks. This mechanism is only utilized within a network collision domain, for example an Ethernet bus network or a hub-based star topology network. An Ethernet network may be divided into several collision domains, interconnected by bridges and switches.

A multiple access method is not required in a switched full-duplex network, such as today's switched Ethernet networks, but is often available in the equipment for compatibility reasons.

Channel access control mechanism for concurrent transmission[edit]

Use of directional antennas and millimeter-wave communication in a wireless personal area network increases the probability of concurrent scheduling of non‐interfering transmissions in a localized area, which results in an immense increase in network throughput. However, the optimum scheduling of concurrent transmission is an NP-hard problem.[3]


Cellular networks[edit]

Cellular networks, such as GSM, UMTS or LTE networks, also use a MAC layer. The MAC protocol in cellular networks is designed to maximize the utilization of the expensive licensed spectrum.[4] The air interface of a cellular network is at layers 1 and 2 of the OSI model; at layer 2, it is divided into multiple protocol layers. In UMTS and LTE, those protocols are the Packet Data Convergence Protocol (PDCP), the Radio Link Control (RLC) protocol, and the MAC protocol. The base station has absolute control over the air interface and schedules the downlink access as well as the uplink access of all devices. The MAC protocol is specified by 3GPP in TS 25.321[5] for UMTS, TS 36.321[6] for LTE and TS 38.321[7] for 5G New Radio (NR).
