You must repair a corrupt InDesign file on Mac OS X after an InDesign file gets damage. Even though there is a feature called document recovery in InDesign that prevents from damage inside documents automatically which can occur because of power outrages and system crashes. But on the other hand this functionality can't protect the file being corrupted other possible reasons including bad spot formation, software conflicts and so on. So users need to repair a corrupt InDesign file on Mac OS X sometimes. For this one should check whether the problem is in due to unsupported version of application. For the latest InDesign version you can update it from Adobe site. In case the issue is just because of InDesign preference file then it is resolved through recreating. For recreating InDesign preference file one can try following feasible measures such as:
- After quiting InDesign start application along with holding Control+Option+Command+Shift keys.
- Then dialog box asking "Delete InDesign Preference Files?" need to click yes.
- Now InDesign would launch regenerated preferences along with defaults.
This is the handy way for repair a corrupt InDesign file on Mac OS X. But do remember to backup proper copy of file before starting troubleshooting. Else you have to rely on InDesign Document Recovery Software for regaining lost file.
