Beta 3.2

• Sharp opens again on macOS 10.15 Catalina and 11 Big Sur

Beta 3.1

IMPORTANT: after updating, open Sharp and click Screen Recording, then switch Sharp on in System Settings. macOS asks one last time: from this version on, updates keep the permission.

• Updates no longer turn off Screen Recording
• Native 5K shows up again on iMacs set to a scaled resolution
• Sharp tells you when Screen Recording needs your attention, and continues by itself once you allow it

Beta 3

• Much sharper and smoother on 5K iMacs, thanks to @ivanhreyes
• Colors now match the iMac's own apps
• Resume from iMac
• The display always returns to full screen
• Mirror works with the MacBook lid closed or a Mac mini without a screen
• The update window now lists what's new
• The High Sierra receiver gets all of the above and a Resume button, and its source is now in high-sierra/

Beta 2.2

• Fixes Sharp using a full CPU core after a stream stopped
• Stops connection attempts over Wi-Fi when no cable is plugged in

The High Sierra receiver is unchanged: Beta 2.

Beta 2.1

• Thunderbolt now connects when Advanced › Connection was set to an Ethernet port
• Connects faster: Sharp no longer tries Wi-Fi first
• Sharp now tells you when a new version is available

The High Sierra receiver is unchanged: Beta 2.

Sharp 1.0 Beta 2

New

• Thunderbolt support: connect with a Thunderbolt cable (Thunderbolt Bridge). Preferred over Ethernet, with faster sharpening.
• Cursor states: text, link, resize, move, not-allowed and more now show on the display Mac.
• Smoother cursor.
• Quit Sharp from the menu bar.
• The menu bar shows the active link: Thunderbolt, Ethernet, or a slow 100 Mb/s adapter.
• Local Network permission is requested during setup.

Fixed

• Connection dropping and reconnecting about once a minute.
• Display Mac dimming while in use. It now sleeps when the sending Mac's screen sleeps.
• Black screen at 3840×2160 and other large resolutions.
• Switching Mirror/Extend or resolution no longer requires restarting both apps.
• Stream frozen after the screen saver or a lock.
• Endless reconnect loop when the display Mac is on Wi-Fi; Sharp now says why.
• 100 Mb/s adapters no longer flooded.
• Port conflicts handled.
• Display Mac's own pointer hides while idle.
