My new iMac with FCPX crashes when rendering complex templates and crashes when exporting with Motion 5

Do you mean the application crashes, or you get a kernel panic?

Launch the Console application in any of the following ways:

☞ Enter the first few letters of its name into a Spotlight search. Select it in the results (it should be at the top.)

☞ In the Finder, select Go ▹ Utilities from the menu bar, or press the key combination shift-command-U. The application is in the folder that opens.

☞ Open LaunchPad. Click Utilities, then Console in the icon grid.

In the Console window, look under DIAGNOSTIC AND USAGE INFORMATION for crash or panic reports. A crash report has a name ending in ".crash" and a panic report has a name ending in ".panic" Select the most recent report from each subcategory and post the entire contents — the text, please, not a screenshot. In the interest of privacy, I suggest that, before posting, you edit out the “Anonymous UUID,” a long string of letters, numbers, and dashes in the header of the report, if it’s present (it may not be.)

Please don’t post shutdownStall, spin, or hang logs — they're very long and not helpful.

I have been having the same issue with my late 2012 iMac 27. FCPX and Motion 5 both freeze randomly, usually within a couple of minutes of use. Spinning beach ball, mouse frozen and the only option is to power down and restart. Adding titles in the inspector is a sure way to bring on the problem, or trying to render out is another. I am running the latest versions of FCPX, Motion 5 and Mountain Lion. I migrated everything over from my old 2008 iMac 24. Ironically both apps work fine on the old machine, albeit slowly, but with no freezing.

See below the only Panic report present in Console.

You don't get an on screen crash report when the application crashes?

Try Crash Analyzer from Digital Rebellion on the whole crash report.

Problems such as yours are sometimes caused by files that should belong to you but are locked or have wrong permissions. This procedure will check for such files. It makes no changes and therefore will not, in itself, solve your problem.

First, empty the Trash.

Launch the Terminal application in any of the following ways:

☞ Enter the first few letters of its name into a Spotlight search. Select it in the results (it should be at the top.)

☞ In the Finder, select Go ▹ Utilities from the menu bar, or press the key combination shift-command-U. The application is in the folder that opens.

☞ Open LaunchPad. Click Utilities, then Terminal in the icon grid.

Triple-click anywhere in the line below to select it, then drag or copy it — do not type — into the Terminal window:

find . $TMPDIR.. \( -flags +sappnd,schg,uappnd,uchg -o ! -user $UID -o ! -perm -600 -o -acl \) 2> /dev/null | wc -l

Press return. The command may take a noticeable amount of time to run. Wait for a new line ending in a dollar sign (“$”) to appear.

The output of this command, on a line directly below what you entered, will be a number such as "35." Please post it in a reply.

Hi Linc. I conducted this text. It came up with an instantaneous response of 74
