Broad support for high dynamic range (HDR) video, such as HDR movies and TV shows from Apple or other providers, requires the latest version of macOS and a compatible Mac model. If your Mac, display, video cable, or video cable adapter doesn't support HDR10, video plays in standard dynamic range (SDR).

3. All HDR content plays at resolutions up to 1080p.

External displays

Use the Thunderbolt 3 (USB-C) ports on your Mac to connect to external HDR10-compatible displays:

DisplayPort displays

Use a cable that has a USB-C connector for your Mac and the appropriate connector for the port on your display, which is usually a DisplayPort, USB-C, or Thunderbolt 3 port.

HDMI displays

Use an HDMI cable and a USB-C adapter such as the Apple USB-C Digital AV Multiport Adapter or Belkin USB-C to HDMI Adapter.

Apple Pro Display XDR

Apple Pro Display XDR supports several HDR formats, including HDR10, when used with a Mac compatible with this display.

When an external display tells your Mac that it supports HDR10, your Mac might automatically enable HDR for that display. You can also enable or disable HDR for external displays in Displays preferences.

Getting the best HDR picture

If HDR video doesn't play in HDR or with the quality you expect, try these solutions.

Check your Mac

• Install the latest Apple software updates for macOS Catalina or later. Some HDR features are available only with the latest macOS.
• Choose Apple menu  > System Preferences, click Displays, then make sure that High Dynamic Range is selected. It appears only on third-party displays that support HDR10, not on built-in displays. If you don't want to use HDR, deselect this checkbox.
  
• Choose Apple menu  > System Preferences, then click Battery or Energy Saver. If 'Optimize video streaming while on battery' is selected, your Mac saves energy by playing HDR video in SDR while on battery power. To play in HDR, connect your Mac to power or deselect this checkbox.
  

Check your external display

• Make sure that your display supports HDR10. If the display has its own HDR setting, turn it on or set it to prefer HDR when available.
• Make sure that your display is using the latest firmware from the manufacturer. Check your display's documentation for details.
• Some televisions support HDR only on a specific input, such as HDMI input 2 or HDMI input 3. Check its documentation for details.

Check your media

If you're playing premium content from a third-party content provider, check with the content provider to be sure that they support HDR on your Mac.

Check your cables and other devices

• If you're using HDMI, make sure that the HDMI cable and adapter support HDR10. Apple recommends HDMI cables that have been tested with Apple TV 4K and a wide range of televisions, such as the Belkin UltraHD HDMI Cable. Compatible adapters include the Apple USB-C Digital AV Multiport Adapter and Belkin USB-C to HDMI Adapter.
• If your video connection passes through an AV receiver, sound bar, or other device before connecting to your display, make sure that the device supports HDR10 and is using the latest firmware from the manufacturer. You can test by connecting your Mac directly to the display.

Developing an application for Mac OS, sooner or later you'll want to add an icon to it. And Mac OS uses Apple's own format for application icons - Apple Icon Image format - files with .icns extension. But how does one create such a file?

It is actually not so hard, but there are some tricky moments. I'll cover those and as a bonus I'll show you how to use .icns icon in Qt-based application (deadly simple).

There is an out-of-the-box Mac OS tool for such conversion - iconutil (documentation for which is nowhere to find at Apple's website, so this brief man page is all we have).

However, you cannot just take a random PNG and feed it to iconutil. I mean, you can, but it will give you the following error: Adobe reader xp offline installer.

Because iconutil takes only specially named folders. Just how am I supposed to know about that? And it shows similar short and useless error messages for other things it doesn't like. For example, here's an output for the situation when files inside iconset folder are not named 'properly' or have 'wrong' dimensions:

Go figure.

After a set of trials and browsing the internet I found out (hopefully) all the requirements:

1. First you need to prepare a set of icon pictures and put those into a folder with .iconset 'extension', for example some.iconset;
2. Pictures from this set should be named in a certain way and have specific dimensions.

Correct dimensions can be found in Apple Guidelines. So it's 5 different dimensions, but actually 10 'physical' files as each dimension is represented twice (you'll see why). And these files have to be named according to the following format:

So here's the full list of proper filenames:

At the same time, I've got a commit to my script, and this commit adds more sizes, which supposedly solves some missing size error. I never got such an error, so even though I accepted the commit, I won't add those changes to the article.

Script to automate the process

Adobe premiere hack mac. But that's rather boring to create all those files manually in some graphics editor, right? So let's use sips utility (although, I recommend using ImageMagick, as it gives better quality results):

Better, but still - we have to run it 10 times. So let's write a Python script for that:

The full script is published here.

As an example, I prepared a square picture with a resolution of 2048x2048 and 150 pixel per inch, so there is plenty room to prevent upscaling:

Pass picture path to the script like that:

Adobe premiere cs6 for mac free. The script will:

1. Create a folder ~/Desktop/apple.iconset;
2. Generate 10 files with different dimensions and save those into that folder;
3. Call iconutil on this folder and put resulting apple.icns to ~/Desktop/.

Here's how the final apple.icns looks like in Preview:

So everything from that folder is bundled into one file.

And now the bonus part - how to use .icns as an icon for a Qt-based application.

As I said, it's deadly simple: put apple.icns into your Qt project folder and add the following line into your-project.pro:

And that's it:
