Hello -- I had the same problem and just about 2 minutes ago, received the following info from support. I was told that they are going to release an update making the software compatible with Mavericks and that it was to come out sometime around the end of November. Because I need to make a plan around it, I wrote back for a closer approximation, since we are now into December. Here is what I got in the email from Support:
Thank you for contacting Canon product support regarding software for your PowerShot SX50 HS camera.
Canon is conducting compatibility tests for the current versions of Canon digital imaging software with the shipping versions of the new Mac operating system. Results will be posted soon at www.powershot.com. For now, Canon is not claiming compatibility with this version of Mac OS.
Mac OS X 10.1 and newer come with Image Capture drivers that support most of Canon's digital cameras with USB interfaces. When a compatible camera is connected to a compatible Mac computer running OS X 10.1 and newer, the computer detects the camera and automatically launches Image Capture. This Apple program allows JPEG images in the camera to be downloaded to the Macintosh. Try doing the following to download the images:
1. Click on your hard drive.
2. Open your APPLICATIONS folder.
3. Open the program that says IMAGE CAPTURE.
4. With Image Capture still open, click on the IMAGE CAPTURE menu, found on the top left corner of your screen, next to the Apple icon.
5. Select the option that reads PREFERENCES.
6. The dialogue box that appears should say something like "When camera connected open." From the pull down menu select IMAGE CAPTURE and then close the window.
The next time you connect the camera to the USB and power it on in replay mode, Image Capture should come up and download picture files on the camera.
I haven't tried this yet. Just thought I'd post this info while I had the time. I hope it helps you.
Marie
