Hi, See this link for your first query: How to Use Adobe Photoshop Elements with iPhoto - YouTube For second query, below are the steps to make Photoshop your default app on MAC. You can use these steps to set up default app as Photoshop elements. 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. Then choose Get Info from the menu that appears: Choosing "Get Info" from the menu. 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 Photoshopfrom 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: Selecting Photoshop CC 2015.5 from the list. 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: Confirming the change by clicking Continue. 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. Let me know if you face any issue. Thanks Arshla Jindal
