I downloaded vlc-2.2.1.dmg to my computer and it opens ok. When I try to copy the app to the Application folder I get this error message. enter image description here

When I try to open VLC from the DMG file it runs fine. I just can't move it to the application folder. Any ideas why? I am running OSX 10.6. I thought i was because I didn't have trust applications from the internet turned on but that is not an option in 10.6 enter image description here

  • Validate the MD5 or SHA1 checksum of the vlc-2.2.1.dmg file. MD5: 744fc1aece233e19efa2d6d0adcfc9fd or SHA1: ac20bcdeb18fd21627fd2b08e7bcf295258ad513 and if it doesn't match then re-download the vlc-2.2.1.dmg file. Commented Jul 3, 2015 at 5:30
  • @user3439894 the OP says the VLC runs fine? so what would the checksum do ?

  • @Buscar웃SD, Anytime there is an issue with a downloaded file that there is a published checksum for then one the first steps on the diagnostic tree is to validate it against its published checksum. IMO The first step is to reboot the system and try reproducing the error and if it still errors out then validate the checksum. If it doesn't match then re-download it and try again and validate again before doing anything else and go from there. Also just because a given application might run from within the .dmg file doesn't mean something isn't corrupted or wrong with the .dmg file. Commented Jul 3, 2015 at 13:01
  • @Buscar웃SD, And since there is an error code 36 being thrown the diagnostic process has to start somewhere and validating checksums is an appropriate step. Commented Jul 3, 2015 at 13:02
  • @Paul, I downloaded vlc-2.2.1.dmg file and it copied and pasted as well as dragged and dropped fine. The downloaded .dmg file also matched against its published checksums. Did you validate it against its published checksum? Commented Jul 3, 2015 at 13:06

After you download the VLC.dmg, you double click on it to create a installer and it opens new window that looks like this.


Now just "drag" the VLC.app icon to the Application folder.

Alternatively, copy the VLC.app to the desktop and then move it to the Applications folder.

There are some reports regarding the Finder Error -36.

Try the "dot clean" as described here http://osxdaily.com/2015/02/21/fix-error-code-36-finder-mac-os-x/

and explained here: https://developer.apple.com/library/mac/documentation/Darwin/Reference/ManPages/man1/dot_clean.1.html

  • 1. He already has the .dmg file opened. 2. By default one will not see the .app extension as shown in your picture when the .dmg file is opened. 3. It doesn't make any difference, it can be copied and pasted or dragged and dropped! Commented Jul 3, 2015 at 5:22
  • @user3439894 I am showing what happens when I click on the VLC dmg file

  • I see the same thing that is in this image. I cannot copy and paste it or drag it to the Application folder. It runs just fine when I double click and open it.

  • @Paul, By default the .app is hidden, as well as many others, and the advanced Finder preference [] Show all filename extensions is unchecked and therefore when images are posted for technical support purposes it should be so noted so as to avoid confusion. Not all users check that preference and I've seen many a post in this same context when a user will say e.g. "I don't see that on my system" etc. As to not being able to c&p or d&d yet run the .app bundle from within the .dmg file nonetheless the issue needs to be troubleshot and I've already commented under your question on this.

  • It would not harm if you repair the disk permissions (in the Disk utility). Is it VLC the only app you have problems with ?
