#8911 - 03/18/10 03:25 AM Mystery plist

My mail program was acting goofy so I thought I'd do a quick check of my drive. From a second bootable drive I ran Disk Utility and then Disk Warrior. I got the following reports but not a rebuilt directory.


Disk: "Macintosh HD" The Property List data was checked in 12,685 files. The Resource Data was checked in 14,700 files. The maximum Folder Depth on this disk is 23. This does not exceed the maximum recommended depth. The System Symbolic Link Files were checked and no problems were found. Location: "Desktop"

File: "Localized.rsrc" Detected that the resource header is damaged and cannot be repaired Location: "Macintosh HD/Applications/StuffIt 11/DropStuff.app/Contents/Resources/French.lproj/"

File: "com.apple.iphotomosaic.plist" Detected that Property List data is damaged and cannot be repaired. Conversion of string failed. The string is empty. Location: "Macintosh HD/Users/douglasinglis/Library/Preferences/"

File: ".a23t.mk4e.plist" Detected that Property List data is damaged and cannot be repaired. Unexpected character at line 1 Location: "Macintosh HD/Users/Beverley/Library/Preferences/"


For the Stuffit file, I used CleanApp to remove everything Stuffit to the trash and then moved only the applications back from the Trash to the Applications folder.

For the iPhotomosaic file, I simply moved the plist to the Trash. I wasn't too worried about this one as it always says that.

The ".a23t.mk4e.plist" was the head scratcher. I opened the other account and couldn't find it. Even a Spotlight search couldn't locate it.

I returned to my account and re-ran DiskWarrior using the Scavenge function and everything came up roses. However it would be interesting to know what the ".a23t.mk4e.plist" file could have been and why I wouldn't be able to locate it.

Googleing ".a23t.mk4e.plist" reveals that you are not the only one scratching your head.

The dot at the beginning of the file name indicates that the plist in question is invisible by default. Temporarily making invisible files visible (via the Terminal command

defaults write com.apple.finder AppleShowAllFiles -bool YES; killall Finder

or one of the various third-party utilities which provide a GUI front end to that command) should make the file visible.

(To restore the invisibility of invisible files, change the YES in the above command to NO.)

Switch from scratching to guessing:

Trip Down Memory Lane

The conclusion is that the file is a plist file for the registration code for a currently unregistered program, and that the file would become visible upon registration.

"A23T" for some reason is ringing in my head as a type or font management somethingorother. That file is no doubt either a registration or preference file. Knowing the contents of the file may be helpful in identifying it. Were you able to find it? It should be immune to spotlight, but you can use the terminal FIND command probably.

find ~ -name ".a23t.mk4e.plist"

though it's very likely to be in your ~/Library/Preferences/ someplace with an extension like "plist".

If that doesn't find it, try

find / -name ".a23t.mk4e.plist"

Once you find it, tell is where it was, what its creation / modification dates are, and show us a snippet of its contents:

stat (type path here)

and

cat (type path here) | xxd -c 32 | head -n 20

Objective Development makes Little Snitch. That is their Little Snitch Daemon plist. Probably their registration information. The file begins with a period so it is not normally displayed by the finder. Best to leave that alone if you have a registered installation of LS.

I have LS registered here and I see the same file but with no leading period. This may be what LS does if it is not registered is to add the period in front of it?

speculating, I'd say that the period is there to prevent the casual user that is still running the demo, or the expired demo, from easily deleting the plist to reset their demo period?

I dunno... I'm running Little Snitch registered, and I've got no such file, visible or invisible.

Also, unless LS has changed over the years I've been a registered user the demo is freely and easily renewable for as long as you want to deal with the bother (every 6 hours as I recall).

There are two issues in play here: (1) what to do about any problem(s) caused by this mystery plist, and (2) which program does it belong to.

Limiting myself here to the latter, I agree with Artie that it's most likely NOT LittleSnitch, as this utility contains clearly recognizable strings like 'LittleSnitch or 'LS'' in its plists (personal observation). Apparently current LS versions no longer contain the string '23' (e.g., at.obdev.LSD.plist or at.obdev.LittleSnitchConfiguration.plist).

Google produces only a few (fairly recent) hits when searching for 'a23t.mk4e.plist'. My personal favorite for the source program is Mortal Kombat 4 Enhanced. tongue

That worked great and I found the file in the Prefs folder. Thanks, I'll store this away in case I ever need it again.

I couldn't get either of these to work, so I assume I may not know the right way to enter the path. In either case, if I entered what I thought was the path using the brackets, I got:

-bash: syntax error near unexpected token

If I did the same without brackets I got:

No such file or directory

At any rate, I checked the plist with Get Info and found that both the Creation and Modified dates were the same and they corresponded with a day this user got one of those internet greeting cards.

This user would not install anything so I'm assuming it's from the card.

Still would be nice to view the contents (to be sure). Did you look at it with TextEdit? (or better yet, a hex-editor such as 0xED).

While the output is nice to hear about, copying the full session from the terminal screen (especially including the commands *you* had entered) is the way to go, if we are to properly discuss what really happened. [brackets?? where??]

Yup. I almost always include the -x option with find (to prevent it from diving deep down inside the /Volumes folder. It will also search networked shares in such cases). Obviously the permissions stuff was due to not prefixing with sudo. [ryck, those last 2 sentences were for primarily for Virtual1's consumption. wink ]

Odd/curious. You (or some user) seem to have strange junk in the home folder which is not accessible by the (home) owner. If interested, we could pursue that here (mods/admins willing) or in another thread.

imac 300HD 4 Gb ram TTP D/W tinkertool.

[Like ryck] I too was having problems with my email, [and] I previously posted that my imac was running slow so like ryck, I ran D/W, TTP, deleted all languages in tinkertool.
D/W told me that there were several property list data could not be repaired along with some others. I noticed that all these files were located in 2 recovered file folders. I deleted them and ran D/W again and that solved that.


However my email problem still persisted (I wasn't receiving any mail that was sent when my computer was off. If someone sent an email whilst I was using it, then I received them.) I phoned my mail server and the first 2 technicians couldn't find out why. The third one was conversant with macs and after adjusting my mail settings, sent me a test email which of course I received.

He then suggested I shut down and he would send me another email which did not come through. He checked at his end about missing emails and told me that someone was receiving them. He had never heard of such a problem and said whoever was receiving them must be using the same password which I thought should be impossible unless like he thought, someone was intercepting them by whatever means. He said to change my password which we did and since then, my emails are coming through.


I mention this [possibly related email issue] in case someone else may encounter the same problem.

I tried the "hit shift" but couldn't seem to get any result other than the first, which was the same as TextEdit:

The brackets are those in Virtual's instruction. i.e. stat (type path here) became stat (User/Beverley/Library/Preferences)

I have no idea what "streamtyped" is for.

plists that are in binary format must be converted to something text based first

you can convert plists with plutil:

plutil -convert xml1 filename.plist

and then view it in a text editor. but I don't think that's a "normal" plist?

Nothing to worry about... just looks like very disposable debris (from a sloppy update program or something).

I agree... it's some sort of "freeze dried" Cocoa (code), tucked into a file with a .plist extension added. That's probably why DiskWarrior (and Drive Genius) seem to think it's a corrupt plist... because it's not really a plist. [which does however make it somewhat suspicious, imo.]

After some digging, i found a very similar header structure in (at least a few) objects.nib files:

xxd -l 16 /Applications/iSync.app/Contents/Resources/English.lproj/iSyncMain.nib/objects.nib
0000000: 040b 7374 7265 616d 7479 7065 6481 e803 ..streamtyped...

Only the last byte differs (out of the first 16).

We could probably get more out of it using the strings command (to save space in the forum window).

So, I think I should get rid of it. Here's what I think I need to do.

1. Enter that User account and make Invisibles, visible.

2. Go to the Prefs folder and drag the suspect plist to the Trash.

3. While in this mode (Invisibles are visible), empty the Trash.

4. Make the Invisibles invisible again.

However, I wonder if I will cause a problem as another Invisible normally in the Trash will now also be gone. I was thinking about the DS_Store. Will the System software just generate a new one, the way it does with some prefs?

Well, if you're going to use the Terminal command posted above to make stuff visible... may as well just save a ton of time and use Terminal to remove the file in a blink of the eye.

May i request we study it for a moment longer? This command will display extended attributes (if any), which could be interesting:

xattr -l /Users/Beverley/Library/Preferences/.a23t.mk4e.plist

Also... if this command doesn't produce too much output, please post:

strings /Users/Beverley/Library/Preferences/.a23t.mk4e.plist

A total non-issue.

First off, items in the trash get erased whether visible or not. Second, we don't care about .DS_Stores in the trash [partly because (as just mentioned) they get erased when the trash is emptied anyway, but also] since they don't contribute anything to our "view" of the trash. All that info is kept in com.apple.finder.plist

It may be of interest to note that: the window we get when we click on the trash icon in the dock is not a real folder. That "container's" view is fabricated. It is manufactured to abstract the union of all trash folders for which the current user has read access. That's how items from other mounted volumes appear in "our" trash.

I don't think it was anything bad... just unconventional.

If you would like to use Terminal to eradicate it, here are two choices...

RM - the basic Unix "remove" (for simple files like this, one could also type unlink):
rm -f /Users/Beverley/Library/Preferences/.a23t.mk4e.plist

SRM - Apple's own "secure remove" to which i like adding the verbose option (for visual progress):
srm -fv /Users/Beverley/Library/Preferences/.a23t.mk4e.plist

Warning: those commands make stuff go away instantly... and there is no
"undo". So be sure the files they're aimed at are truly not needed anymore.
