Macs   are a powerful machine . Unlike Windows , they just work . You grow it ON , do your study and then turn it OFF . However ,   today while I was set up an OpenVPN   customer on my iMac ( macOS Sierra Version 10.12.6 ) I capture a weird error saying .

You ca n’t open up the program ‘ app name ’ because it may be damaged or incomplete

The first mentation was to re-start the twist , and when I did that , the affair went south . Now , I was not capable to give any app even the system app was not solve . After a turn of Google search , I came across this forum which recommend re-start the Mac to safe style and doing all kind of geeky clobber . Now , I usually wish troubleshooting software problem but not today . I had a deadline .

You can’t open the application ‘app name’ because it may be damaged or incomplete

After hr of Google lookup , I came acrossthis answeron Apple assembly by the userLinc Davisand surprising it process . And the honest part is , it only   takes   2 minutes to fix everything . However , my   experience   was a niggling piece different from what he had save so , I decide to rewrite this egress .

Fixed: You can’t open the application because it may be damaged or incomplete

Note : Before we start out , please back up all data to an external hard driveway . The following workaround is just one solution that worked for me and some other people , there is no guaranty that it ’ll work for you . So   proceed at your own risk .   Once done , follow the steps .

1 . select the discoverer icon and then go to the top menu bar . Click onWindow > Go to Folder

2 . Copy paste or manually typecast the following folder location .

You can’t open the application ‘app name’ because it may be damaged or incomplete

/var / folders

3 . A new booklet will toss off open , Inside   that you ’ll see several subfolders , each with a two - character name like‘4v , hr , tv , zz ‘ etc . This could be same or different for you .

Now according to the original poster , you need to tangle all the subfolders   except   the one nominate “ zz ” to theTrash .   Do n’t erase the subfolder nominate “ zz ” .   You ’ll be incite for your administrator login credentials .

Go to Folder

However , in my case , I was not able-bodied to edit any folder except “ hr ” , and even that reappear once I delete it . But it still fixed the problem . I do n’t know how , but just after that , I was able to open up all the apps again .

4 . Restart the computer and this will fix the mess up icons . You might have to access to your browser app and all the saved account once again , but that should be much of an takings , equate to what you just saw now .

Overall , I still not sure , what was the issue ( might have to do with some important files get corrupted ) and how this workaround fixed this issue . But thankfully it saved me the entire of tedious employment and I desire it works for you as well . Again , all credits go to the user   Linc Davis .
