~/Library/Application Support/ folder sometimes somehow is reset

Another omen is that Launchpad icons are rearranged in an alphabetic order, leaving original built-in icons in the first screen.

OK. I will try and see.

will keep this post updated.

unfortunately, reseting ACLs and home folder permissions won't help.

This morning, again, I deleted an app from Launchpad, and the issue revealed.

Sorry for this, but glad I have compay, and I belive there're more to come.

I've contacted apple, and they've collected all my records for investigation.

Will let you know if got any update on this.

Hi buddy,

Did you install any ntfs for mac? i.e., Paragon or Tuxera ntfs for mac?

Can you share any info?

~/Library/Application Support/ folder lost sometimes when restart

Hi buddy,

I reformated my HDD and recovered the whole new system from online or USB drive bootup.

*ATTENTION:

Make a TM backup, Just in case you wanna fetch any file on the old system.

However, don't recover the OSX system using the backup.

Up to now, the problem hasn't emerged. So I assume it has been fixed, as to the reason, no idea.

Up to now, no problem at all.

I suspect some system files corrupt. For those suffering this odd issue, only one suggestion:

1. Make a full new Time Machine backup including everything.

2. Erase everything on your HDD or SSD

3. Do an online full restore or USB bootable installing drive if you have poor internet (http://www.macworld.com/article/2056561/how-to-make-a-bootable-mavericks-install -drive.html)
