Mavericks install on new MBP went fine, no issues. Install on PM from MLion went fine but after restarting all windows lose focus in 3-5 seconds, forcing you to reclick on the window to continue, the the problem repeats. All apps including finder.
Suggestions for finding the problem? (I will roll back via TM to ML since it is basically unusable at this time. )
It was Cox for me as well. I disabled and no problems for the past 36 hours.
I have talked to the Cox Backup support group in the past (they have their own support number) and will report this issue.
TwahPisto since you have a pretty new machine under warranty with not much installed I would contact Apple support. Should make isolating the problem easier.
Just tried the 10.1 update, still an issue. Uninstalling Cox fixed it immediatley. I will ping the Cox backup support group again.
I'm so glad I found this post. I was so frustrated with my windows loosing focus. I uninstalled Cox Backup and it was fixed immediately.
Found it listed in the Cox Backup uninstaller script.
In Cox Backup, uncheck "Show status in menu bar". My issues went away without uninstalling Cox Backup.
Thanks iMichael -
Your script verified the same app for me as well (corporate Symantec software - I can't uninstall it).
Losing focus every 5 seconds as I type this....
Thank you really much!
I know it is about a year later, but I just had this same problem with Cuda_Drive!
After using the python script to detect (see accepted answer), I was able to confirm that Google Drive was causing this problem.
Thank you for this tip. It worked for me as well.
All windows lose focus after 3-5 seconds
