Warning message in Lion

Thank you Fujitsa

I also find it extremely anoying and its a pitty Apple provides no way of disabling it.

For thos einterested, I have devised an easy work-around for this known issue. It is a but tedious but not too bad until such time as Apple effects a "fix."

1) Download images and after extracted into a folder that you create on your desktop, drag the images into that folder.

2) Open iPhoto, and IMPORT the folder into iPhoto. ALl of the images will easily and without issue import into iPhoto.

3) Go back to DT folder where the original images reside and DELETE them ALL.

4) Go back to iPhoto and select all and copy images and PASTE them in the folder and you are in business!

Good luck!

There IS a work around. A bit of a pain but not too bad. Import your pictures from the downloaded folder into iPhoto. Then delete the original files in your folder residing on your desktop. Then, highlight and copy all of the photos just imported into iPhoto into that folder on the desktop and you're good to go. Preview will open and present normally. The process of importing these zipped files into iPhoto renders them "safe" in the mind of Lion. You can layer delete from iPhoto without issue

Looking for a reference from Apple that this is a known issue. Got some pic's sent to me that triggers the xyz.jpg is an application downloaded from the internet etc. I choose to not open.

I can preview the jpg's in finder and they look ok but I'm suspicious.

Beginning of the file looks like this in a simple editor:

ÿØÿà JFIF ÿþ;CREATOR: gd-jpeg v1.0 (using IJG JPEG v62), quality = 90

If you read the thread, this is a known issue with Lion. Basically the warning will pop up for files that are downloaded from the internet including picture files, ie: .jpgs; so if you downloaded the picture from a trusted source, it should be fine.

Correct; the problem is that one must still go throgh the tediius process of saying "yes, this is safe", and proceed to repeat the same process as many as 100 or 200 times, depending on the amount of files within the zipped file one has downloaded from a "trusted" source. It's ridiculous and I'm sure Apple is workinng on a fix for this as the process is absurd and combersome.

The only person I trust on the Internet is me. If I created the .jpg I wouldn't DL it from the net.

I have read the thread, but I don't trust stuff DL'ed from the net 🙂 IOW's the problem remains.

Peace and love

found this command string from

http://www.macworld.com/article/145324/2010/01/filewarnings.html

no need to reboot, single shot only,

xattr -d -r com.apple.quarantine ~/Downloads

covers ALL files in ALL folders under ~/Downloads

or you could substitute ~/Desktop, etc.

Thanks Brian; I prefer the "case by case" basis approach as I understand it is quite dangerous to routinely diable such warnings. But this command works great and is a quick work-around, Thanks!

Just want to add my experience. I'm running Lion on a new Mac Book pro. I'd prefer if Apple would create some switch in the prefrence panel rather than insert code that completey diables the warning. Or just FIX the warning. I also have files sent to me all the time. I just had a entire website zipped to me. When I open the the image folder to view the .jpg files I get a warning for every freaking one. and NOOOOO these aren't applications. I trust the source.

Guys and gals: I have spoken with upper level support and currently there is no fix OTHER than the one described in this thread, OTHER than the BETTER one I have figured out!

1. Open up iPhoto and IMPORT all of the files within this folder. Phots will import normally and without issue.
2. Delete the filers residing in your imported folder, presumably in residing on your desktop.
3. Copy and then paste the photos from iPhoto in to the now empty folder residing on your desktop.
4. Return to iPhoto and then delete the photos you've just imported, The files now residing in your folder on the desktop will open without issue.

Apple is working on a fix, but it could take weeks or months.

I hope this helps!

I also have this annoying problem, but with a bunch of mp3 files.

I copied some mp3's from my imac to my macbook (both with lion, but the files were downloaded on snow leopard long time ago, from a trusted source), and i got the message telling me that the mp3 files were applications.

The strange thing is, i redownloaded the exact same files, from the same source and i didn`t get the warning when opening them.

I've been getting this same message for the past week ever since upgrading to Lion. I love everything about Lion ... except this!

Thanfully, the command below fixes it without me taking it off the whole system (which I hear is a major security risk).

xattr -d -r com.apple.quarantine ~/Downloads

Just replace "~/Downloads" with the path where you usually download your files, and it works like a charm! No restart needed 🙂

As most you say, this is a known issue. I never had this warning when I was using Snow Leopard. Began with my new MacBook and Lion.

And for what matters, in my case, it happens to apps and unzipped files (images or pdfs)... Every app I downloaded from the Mac App Store works fine. Skype, Chrome, Firefox, downloaded from their sites with Safari, also shows the warning every time I open them, even in the same session. I don't mind having this one time, the first time I open an app or downloaded file (always from sites & people I trust) but every single time since downloading or installing is annoying.

The terminal command to completely disable the warning is dangerous of course, if it feel dangerous to someone, then just don't use it.

I do prefer the termnal command that turns off quarantine of folder mentioned above, or removing the quarantine just for the app:

xattr -d -r com.apple.quarantine /Path/to/application/

Hope this helps.

Thanks for this; as already mentioned it is EXTREMELY annoying to have to "allow" access to a simple .png file before opening it up with Preview (oh how the times have changed... yeah I'm talkng about that stupid Vista security warning that the first thing users did was disable... seems we are now in a similar camp!) however I took it one step further (security wise) and made a new folder named SafeDownloads. I move "things" I download and have confirmed safe into this folder. I did not want to disable the automatic checking on my ~/Downloads folder since Safari will auto-run "safe" downloads ;-)

One thing I did notice is you have to update this command:

xattr -d -r com.apple.quarantine ~/SafeDownloads

everytime you update the folder, which I'm assuming you had to do with the ~/Downloads folder too. Hmm, maybe it's because most of my files are in sub-folders. doesn't matter I have an Automator folder action attached to ~/SafeDownloads so every time it gets updated, it is re-run.
