I've accidentally deleted my iBooks app on my OS X

Hi alienxp03,

I understand you have deleted the iBooks app from your MacBook Pro by mistake. If you have not emptied the trash yet on your computer, you should be able to open the Trash, right-click on the item and choose "Put Back" from the contextual menu.

If you have a Time Machine backup of your system, you should be able to restore the file from an earlier point.

I'll include some information about both of these options below:

Get to know the Finder on your Mac

Delete files

To move a file to the Trash, drag the file to the Trash in the Dock. Or select one or more files and choose File > Move To Trash (Command-Delete).

To remove a file from the Trash, click the Trash to open it, then drag the file out of the Trash. Or select the file and choose File > Put Back.

To delete the files in the Trash, choose File > Empty Trash. The storage space used by those files then becomes available for other files.

Restore from a Time Machine backup

Restore specific files:

1. Choose Enter Time Machine from the Time Machine menu , or click Time Machine in the Dock.
   
   
2. Find the files to restore:
   • Use the timeline on the edge of the screen to see the files in your Time Machine backup as they were at that date and time. The timeline may also include local snapshots.
   • Use the onscreen up and down arrows to jump to the last time the contents of the window changed. You can also use the search field in a window to find a file, then move through time while focused on changes to that file.
   • Select a file and press Space Bar to preview the file and make sure it's the one you want.
3. Click Restore to restore the selected file, or Control-click the file for other options.

Take care,

Hi alienxp03,

You could check to see if the iBooks app is included in the past purchases for your Apple ID. If it is not, then you would need to make a backup of your computer, and reinstall your existing OS X or upgrade to the newest one to get the iBooks application reinstalled.

Take care,

I deleted iBooks on purpose (I prefer to keep my books in iTunes since I don't read on my laptop) and twice it has come back automatically with an update. So you might check the App Store and see if there are any updates you haven't downloaded.
