Did you just recently upgrade to 10.9.5 - such as about the same time you started having Premiere Elements problems?
Note - I'm Windows, but in the past week I have read a LOT of Mac problem messages where 10.9.5 MAY be the common factor (not just in this forum... also in other forums)
I actually started experiencing the problem about a week or two BEFORE the update to 10.9.5
Premiere Elements 11 or 13 on Mac Computer.
Which program do you want to troubleshoot first?
Let us assume Premiere Elements 11....
1. Edit Menu/Preferences/Scratch Disk
Where are the Scratch Disk pointing and how much free space is at that location
Please assure a clean up of any pile ups of any preview files (Adobe Premiere Elements Previews File Folder), conformed audio files (Media Cache Files Folder), and conformed audio (best cleaned out through Edit Menu/Preferences/Media and the Media Cache Database area Clean button.
2. Download, install, and run the free ccleaner.
3. How much installed RAM does you computer have? Are your source media stored on external hard drive (with the appropriate formatting for Mac)?
4. Does the information in online articles such as the following make any impact on your situation?
Let us start here and then decide what next.
I am strictly and Elements Windows user who tries to find common ground between Premiere Elements Windows and Mac to address some of these issue. So, I am
not all that great on Mac locations. Please help me translate from Windows to Mac if necessary.
