Directory enumeration gives wrong file type for aliases

I am trying to enumerate the contents of a directory (aka folder) using NSDirectoryEnumerator. My problem is that the file attributes always returns NSFileTypeRegular, no matter whether it is an alias/symlink or a regular file. You can see my code below. I have tried to retrieve the file

Can a Spotlight search follow aliases / symlinks?

I am doing Spotlight searches using the NSMetadataQuery API. Usually, my search is limited to a specific folder. Is it possible to make it follow aliases (and symlinks) that might exist in that folder? I am especially interested in aliases/symlinks that point to other folders. Or do I have to

Help - Epic Browser SPDY Encrypted Proxy Failing in Sierra

For some mysterious reason our SPDY encrypted proxy fails in our chromium based browser only in Mac OS X Sierra. It works fine in every other operating system. We're getting a "CERTIFICATE_INVALID_ERROR" even though our certificates are of course fine. If you have any idea what's causing this,

Logging in macOS 12

Some app with NSLog (not running in Xcode) does not show anything in Console.app. Only when Iog in as administrator I can see the NSLog lines. Is this working as expected? Can anything be done to make common people see the NSLog lines too? Gerriet.

deleting connections in .xib

Hello, I haven’t found a way yet to delete actions, outlets etc. using the xib interface. I’ve resorted to editing the project bundle with a text editor. Surely that isn’t the way this is supposed to be done? Any pointers appreciated. Jan E. ___

How to count Atoms

I need (just for debugging purposes) to count something in a thread safe way. This works, but is deprecated: SInt32 counter; - (IBAction)doSomething:sender { counter = 0; some loop { IncrementAtomic( );// 'IncrementAtomic' is
