App Store :: Deleted Mac Certificates - Application Damaged And Cannot Be Opened

May 24, 2012

I messed around with my certificates in the keychain, because I have troubles with it in xCode. The problem is, I accidentally deleted also certificates for the Mac App Store. Now every app from the Mac App Store says:

"[name]" is damaged and can't be opened.
Delete "[name]" and download it again from the App Store.

Which certificates, keys etc. Do I need and where can I get it? (I have a second Mac activated for the Mac App Store but no backup for this Mac.)

PS: Mac OS X 10.6.8 (Snow Leopard)

App Store :: Deleted Application From Mac But Update Still Showing In List

Apr 4, 2012

I have a issue with my app store. When I downloaded a free app from the app store and later decided that I do not need it, I just erased it. What I have observed is that the updates for the application are still in the list in the app store. I tried to install the application again, and install the update, but when the new updates came out, it started repeating.

OS X Yosemite :: Error Message Says Preview Is Damaged And Can't Be Opened?

Dec 11, 2014

Whenever I try to open a file associated with Preview by double-clicking the file I get the following error message...

If I open Preview first and then open the same file from within Preview it works fine. I've tried going into Info for various filetypes and changing the "Open with:" value to change it to something else then change it back to Preview but that doesn't change the behavior. As you can see in the error message it says "Acorn created this file on August 27, 2014"... what that means. I tried deleting the Acorn app but get the same error message..

Jun 17, 2012

Tried to turn off computer and it kept prompting me to force quite various applications. I have since restarted the computer but now am getting this error when trying to open Finder. I have looked through several discussions and unfortunately am not an apple expert so much of what I am reading is foreign to me.I have opened the Terminal and entered a prompt that made all of my desktop docs and finder visable, but as soon as I closed out the Terminal it all disappeared again.Can anyone point me in the right direction - step by step - to get Finder back up and running.To my knowledge all other applications seem to be working as normal.FYI I do have a few extermal items attached to the Mac. (1) extermanl hard drive for the Time Machine, and USB drive.

OS X V10.7 Lion :: Application Switches Spaces When Opened From Finder

Feb 8, 2012

I am using Lion 10.7 , I assigned dreamweaver to desktop1 by choose Options > This Desktop when in desktop1. Then relaunch DW and it correctly opened in desktop 1. Now if i open a file using in finder (which is itself assigned to desktop3) on a file that is default to DW then Dreamweaver moves itself to Desktop3.

I thought the point was that we could assign different applications to different spaces and they would stay that way. Are we saying that if a file is opened from finder its default application will be moved and set up of spaces does not apply ?.

OS X V10.7 Lion :: Delete An Application That Says It Cannot Be Deleted?

Feb 6, 2012

I installed a game called PlaneShift and now want to uninstall it. It does not appear to have an uninstaller. When I try to move the file the client is in, the client itself, or any of the other files in the folder to the trash I get a message that says this cannot be done because the file cannot be deleted. The file stays where it was and nothing happens. The file is not locked nor is the application running. I even downloaded CleanMyMac to delete it which would claim to have done the job yet the folder and everything it it would still remain. Googling it yielded some commands to put in to the terminal to delete it with the root account

Are Cancelled Mac App Store Downloads Deleted

Jun 12, 2012

I was attempting to download a 3 GB application from the Mac App Store. I cancelled it as it was slowing down my internet speed, but now I am redownloading it. I am worried that the file might still be on my computer as Launchpad still showed the progress bar even after I closed the App Store application. The file downloaded was close to 1 GB and I can't tell if my Mac automatically deleted the file for me.
