May 07, 2015 Let’s cover everything one by one so you understand how they all appear and function across your Mac. First, the default view will open to “All” your third-party extensions. These are the result of other software we’ve installed. Below each third-party extension, you see where it appears along with a checkbox to enable or disable it. May 20, 2019 In Microsoft Outlook 2016 for Mac running on Mac OS X Yosemite (10.10) or later versions, you cannot set Outlook as the default application. In Outlook Preferences, under General, you enable the Make Outlook the default application for e-mail, calendar, and contacts option.However, when you check the general preferences again, this option is not enabled.
System extensions on macOS Catalina (10.15) allow software like network extensions and endpoint security solutions to extend the functionality of macOS without requiring kernel-level access. At WWDC19, we announced the deprecation of kernel extensions as part of our ongoing effort to modernize the platform, improve security and reliability, and enable more user-friendly distribution methods. Kernel programming interfaces (KPIs) will be deprecated as alternatives become available, and future OS releases will no longer load kernel extensions that use deprecated KPIs by default.
Jun 05, 2016 Maybe you want all JPG picture files to open in a photo editor instead of OS X Preview. These and other file types open in a default program set by the operating system. The installation procedure of some apps will change the default. They’re not supposed to change the default Mac app for a file type without the user’s agreement. Oct 08, 2009 Is there a quick way to change the default program that opens certain file extensions? For instance, I have dozens of flv videos that suddenly open with a Finale (music notation program) video information page! I can't imagine what happened, but obviously the files won't play. I want the default program to be QuickTime Player. Disk image files that are stored in the DMG file format and are appended with the.dmg extension are intended as virtual disks for Mac OS X platforms. These DMG files can be mounted unto a virtual drive or directly activated to launch the Apple Disk Utility program, in order to view and use the content of these.dmg files.
Transitioning Your Kernel Extensions
If your software uses deprecated and supported KPIs, you’ll need to factor out deprecated components into a stand-alone system extension. If your software uses new system extensions and legacy kernel extensions, you can distribute to supported operating systems. Software that supports a broad range of macOS versions should continue to use kernel extensions for older versions and run system extensions where supported.
Below is a list of deprecated KPIs as of macOS 10.15. In macOS 10.15.4, use of deprecated KPIs triggers a notification to the user that the software includes a deprecated API and asks the user to contact the developer for alternatives.
KAUTH
Please use EndpointSecurity instead of the following deprecated KPIs:
- kauth_listen_scope
- kauth_unlisten_scope
Network Filter
Clients should use NetworkExtension instead of the following deprecated KPIs:
- ipf_addv4
- ipf_addv6
- ipf_inject_input
- ipf_inject_output
- ipf_remove
- sflt_attach
- sflt_detach
- sflt_register
- sflt_unregister
- sock_accept
- sock_bind
- sock_close
- sock_connect
- sock_getpeername
- sock_getsockname
- sock_getsockopt
- sock_gettype
- sock_inject_data_in
- sock_inject_data_out
- sock_ioctl
- sock_isconnected
- sock_isnonblocking
- sock_listen
- sock_receive
- sock_receivembuf
- sock_send
- sock_sendmbuf
- sock_setpriv
- sock_setsockopt
- sock_shutdown
- sock_socket
- sockopt_copyin
- sockopt_copyout
- sockopt_direction
- sockopt_level
- sockopt_name
- sockopt_valsize
IOHIDFamily
All KPIs in IOHIDFamily are deprecated. Clients should use HIDDriverKit instead.
IOUSBFamily
IOUSBFamily has been deprecated and headers removed from SDK since macOS El Capitan (10.11). All clients should move to IOUSBHostFamily or USBDriverKit, where appropriate and outlined below.
USB Networking
The combination of using IONetworkingFamily KPIs as well as any USB KPI (IOUSBHostFamily or IOUSBFamily) is deprecated. USB KPIs have alternatives in USBDriverKit . Clients of IONetworkingFamily KPIs should use NetworkingDriverKit instead.
USB Serial
The combination of using any IOSerialFamily KPI as well as any USB KPI (IOUSBHostFamily or IOUSBFamily) is deprecated. USB KPIs have alternatives in USBDriverKit. Clients of IOSerialFamily KPIs should use SerialDriverKit or USBSerialDriverKit instead.
USB Vendor Specific IPC
Any kernel extension using USB KPI (IOUSBHostFamily or IOUSBFamily) that does not tie into the IO Family subsystem and uses IOUserClient, or subclasses, for IPC is deprecated. USB KPIs have alternatives in USBDriverKit or consider IOUSBHost. DriverKit also has mechanisms for communication channels.

Learn how to make Adobe Photoshop your default image viewer and editor for popular file formats like JPEG, PNG and TIFF, as well as Photoshop's own PSD format, in Mac OS X.
Even though every copy of Photoshop, whether it's a standalone version or part of a Creative Cloud subscription, includes a free and powerful file management program called Adobe Bridge, many Mac users still prefer the Finder for locating and opening their images.
While there's nothing technically wrong with that, there is one annoying problem; Mac OS X, at least by default, ignores Photoshop when we open images directly from within a Finder window. Instead, it prefers to open them in Apple's own Preview app with its basic and very limited set of image editing features. Since Photoshop is obviously our editor of choice, let's learn how to easily configure Mac OS X so that our images will automatically open for us in Photoshop every time.
Note that this tutorial is specifically for Mac users. For the PC version, see Make Photoshop Your Default Image Editor in Windows 10.
This is lesson 2 of 10 in Chapter 2 - Opening Images into Photoshop.
Turning On File Name Extensions
First, navigate to a folder on your Mac that contains one or more images. Here, I've opened a folder that's sitting on my Desktop. Inside the folder are four image files. Starting from the left, we have a PNG file, a JPEG file, a Photoshop PSD file, and a TIFF file. How do we know which file type we're looking at? We know because of the three letter extension at the end of each name:
A Finder window showing four image files.
If you're not seeing the extensions at the end of your file names, go up to the Finder menu in the top left of your screen and choose Preferences:
This opens the Finder Preferences dialog box. Click the Advanced tab at the top, then select Show all filename extensions by clicking inside its checkbox. Close the dialog box when you're done. You should now see the file extensions listed at the end of your file names:
Click the Advanced tab, then check 'Show all filename extensions'.
The Default Image Viewer
Let's try opening one of the images to see what happens. I'll double-click on my JPEG image ('fashion.jpg') to open it:
Opening a photo by double-clicking on its thumbnail.
Even though I have the latest version of Photoshop installed, and even though Photoshop just happens to be the world's most powerful image editor, Mac OS X completely ignores it and instead opens my photo in its own Preview app (fashion photo from Adobe Stock):
Preview has a few image editing features, but it's no Photoshop.
That's obviously not what I wanted so I'll close out of the Preview app by going up to the Preview menu at the top of the screen and choosing Quit Preview:
Making Photoshop The Default Image Viewer And Editor
So how do we tell Mac OS X to open this image in Photoshop instead of in Preview? And more importantly, how to we tell it to use Photoshop not just for this one image this one time but for every JPEG image we open in the future? It's actually very easy to do. First, Control-click on a JPEG image you want to open:
Control-clicking on the JPEG photo's thumbnail.
Mac Default Email Program
Then choose Get Info from the menu that appears:
A long, narrow Info dialog box will open full of details about the image. Look for the section that says Open with. You may need to click the small arrow to the left of the section's name to twirl it open. This section tells us which program Mac OS X is currently using to open JPEG files. By default, it's set to Preview:
Preview is currently our default image editor.
Click on 'Preview.app' to open a list of other apps currently installed on your system and choose Adobe Photoshop from the list. If you have more than one version of Photoshop installed, choose the most recent version. Again, at the time I'm writing this, the most recent version is CC 2015.5:
There's just one step remaining. To set Photoshop as the new default app for opening all JPEG files, not just this one, click the Change All button:
Clicking 'Change All'.
You'll be asked if you're sure you want to open all JPEG files (that is, all files with a '.jpg' extension) with Photoshop. Click Continue to confirm it:
You can close out of the Info dialog box at this point, and that's all there is to it! Photoshop is now set to open all of your JPEG files. I'll double-click once again on my JPEG image in the Finder window:
Opening the same photo again.
And sure enough, instead of opening in the Preview app as it did before, this time the photo opens for me in my latest version of Photoshop:
Photoshop is now my default image editor for JPEG files.
PNG Files
So far, so good. We've set Photoshop as the default app for opening JPEG files. But we still need to set Photoshop as the default app for opening the other file types as well, so let's run through the steps quickly. I'll return to my Finder window, then I'll Control-click on my PNG file ('butterfly.png') and choose Get Info from the menu:
Control-clicking on the PNG file and choosing 'Get Info'.
This opens the Info dialog box where we see that Preview, not Photoshop, is currently set as the default app for opening PNG files:
I'll click on 'Preview.app' and select my latest version of Photoshop from the list. Then, to set Photoshop as the default app for all PNG files, I'll click Change All:
Changing 'Open with' to Photoshop, then clicking 'Change All'.
I'll confirm that I want all PNG files to open in Photoshop by clicking Continue:
Then I'll close out of the Info dialog box. And now, when I open my PNG file from my Finder window by double-clicking on its thumbnail, the image opens in Photoshop, as will all PNG files from now on (butterfly design from Adobe Stock):

TIFF Files
Let's do the same thing for TIFF files. I'll return once again to my Finder window where I'll Control-click on my TIFF image ('portrait.tif'). Then, I'll choose Get Info from the menu:
Control-clicking on the TIFF file and choosing 'Get Info'.
In the Info dialog box, we see that just like with the JPEG and PNG files, Mac OS X is using Preview to open TIFF files. It's possible that your system may have a different app selected so don't worry if it does. All that matters is that we change it to Photoshop:
I'll once again click on 'Preview.app' and select my latest version of Photoshop from the list. Then I'll make the change apply to all TIFF files by clicking Change All:
Changing 'Open with' to Photoshop, then clicking 'Change All', this time for TIFF files.
I'll click Continue to confirm the change:
Then I'll close out of the Info dialog box. And now when I double-click on my TIFF file to open it in the Finder window, we see that it opens automatically in Photoshop (portrait photo from Adobe Stock):
Mac Os Default Programs

PSD Files
Finally, while Mac OS X will usually set Photoshop as the default app for opening PSD files (since PSD is Photoshop’s native file format), it still never hurts to check. Plus, if you have multiple versions of Photoshop installed on your computer, it’s worth making sure that your PSD files will open in the newest version, as we're about to see.
I'll return one last time to my Finder window where I'll Control-click on my PSD file ('performer.psd') and choose Get Info:
Control-clicking on the PSD file and choosing 'Get Info'.
In the Info dialog box, we see that sure enough, Mac OS X is using Photoshop to open PSD files. But, there's a problem. I still have older versions of Photoshop installed on my system, and Mac OS X has chosen one of the older versions, not the newest version. Here we see that it's set to use Photoshop CC 2014, while the newest version (at the time I'm writing this) is CC 2015.5:
Photoshop is set to open PSD files, but it's the wrong version of Photoshop.
I'll click on 'Adobe Photoshop CC 2014.app' and choose the latest version of Photoshop from the list:
Then, as I've done with the other file types, I'll make the change apply to all PSD files by clicking Change All:
Clicking 'Change All'.
I'll click Continue to confirm the change:
Then I'll close out of the Info dialog box. And now when I double-click on my PSD file in the Finder window, it opens automatically in my latest version of Photoshop (performer photo from Adobe Stock):
