Warning message in Lion

That is an extremely dangerous thing to do. Those warnings are in place to help you avoid opening malware on your computer. If they are malfunctioning, you need to address that problem rather than just turn them completely off!

"Extremely dangerous"? I don't think so. Not even slightly risky if you know what file you are downloading and it's source.

Same problem here. It's very annoying and even workflow disrupting. I disabled it with Terminal as explained in this thread.

This is not the first big problem Lion is giving me. I use Mac OS since Tiger and I always updated without significant troubles until now. Really disappointed with this Mac OS release.

I have the same issue after updating to Lion, really annoying. Apple please fix it!!!!

Thanks Fujita. I disabled the messages. I don't want to approve every mp3 radio program I open that I receive from a friend (i.e. trusted source). It works great now. No message. One less button to click. Yeah! I understand this message serves a purpose... I guess. But, for some people who know what they're downloading/doing these messages are a bother. For others who don't know what they are downloading/doing they get used to these message and just click, click, click through them without thinking after awhile.

Anyway, thanks for the tip! 😎

BTW, I downloaded these mp3 files from my MobileMe account where I told my friend to upload them to!

Same issue for me as well. Get it with various d/l (i.e., not all) .jpg, .rar, .zip and application files.

I've just downloaded 800 pdf files of patents from an on-line database, just like I do every month. I used to be able to open them in batches of 20 or so, now only 3 or 4 open, each with the warning message.

It's driving me nuts too!

Message was edited by: histon_mike Thanks to the edit in Terminal in the message above - problem solved, can open 20+ pdfs at a time without the warning message. Life back to normal.

I am getting the exact same warning with every file I open that has been downloaded. Most of the files are PNG or JPG files. It doesn't seem to matter if they were all in the same zip file, I get the message for each file. It is extremely annoying.

I tried to disable this feature in Terminal but was not sucessful! I don't want to have to open every file this way! There has to be some fix!

Try the Terminal trick posted earlier in this thread and then restarting. Worked for me. YMMV.

I tried that. Are you running Lion?

Yes.

The advice from Fujita Senpai from earlier should work. It worked for me and other people as well. Just be sure to copy the green text below, open terminal, paste in that command and then hit your enter key. Then close terminal and after a restart it should be fine. I have not had the annoying messages since doing this. I hope this works for you. I would encourage you to give it a try once more.

Fujita's message:

I for one find these warnings extremely annoying and chose to disable it completely using the Terminal.

Just input:

defaults write com.apple.LaunchServices LSQuarantine -bool NO

and restart.

Should you choose to enable it again just change NO to YES. Pretty straightforward.

I believe I got it! I was not hitting the ENTER key afterward. Thank you so much! I was going to be crazy if I had to keep seeing that warning.

Yes. Thank you. I did this, and it works. This issue was driving me nuts. Even though it was obviously not a solution Apple would reccomend. I just could not wait for a fix. I was seriously considering downgrading back to Snow Lion. I open jpegs from zipped files all the time, and was wasting way too much time opening each image one by one so I could press "OK" on each warning that came up, since I could not open images in a group because of this warning.

Thanks again.
