Will any files or apps delete after updating to Mavericks?

I'm downloading the update right now and I would like to know if any of my files or app gets deleted after this update... I'm sure many people here already installed the update so what can you say?

Solution 1:

I have been running Mavericks for about two weeks and I haven't noticed any apps that were deleted during the install. Some of Apple's apps may be updated during the upgrade, but I'm not aware of anything that gets deleted.

Solution 2:

The upgrade to Mavericks overwrote the config file for the Apache web server (localhost). It also overwrote the environment variable giving access to Java.

Solution 3:

From my upgrade experience, nothing has been lost in the process. All application settings are the same, all the applications are there and all the files are still here.

Upgrading an operating system should never touch your personal information and your installed applications unless you are doing a clean install, but if you are simply running the "Install OSX Mavericks" application, you have nothing to worry about.

However, the only thing that does get deleted is the installer itself once you have finished upgrading. If you would like to keep it to either create a bootable recovery USB or use the installer to upgrade other Macs you own, you can either copy it to a USB or some other form of storage besides your boot hard disk or simply make a copy of it in a compressed zip folder which wont be deleted regardless of its location.

Hope this helps!
