I purchased adobe photoshop elements 13 from dell to download on my Mac OS Which has been updated to maverick. When i download the link it goes into the download bucket and tells me to choose an app to open and I can't figure out which app to choos

if you have a serial number, and if you follow all 7 steps you can directly download a trial here:  Adobe Photoshop Elements 13 Direct Download Links, Premiere too | ProDesignTools

and activate with your serial number.

if you have a problem starting the download, you didn't follow all 7 steps, or your browser does not accept cookies. 

the most common problem is caused by failing to meticulously follow steps 1,2 and/or 3 (which adds a cookie to your system enabling you to download the correct version from adobe.com). 

failure to obtain that cookie results in an error page being displayed after clicking a link on prodesigntools.com or initiates the download of an incorrect (eg, current) version.
