Hey KeyLemon, where are the themes you said are available on your website? I looked all over and didn't find any.

I bought the Gold version of KeyLemon yesterday after having tested it for a relatively long time. I verified its installation and deinstallation procedure several times before buying it and never experienced a single issue. As the developer rightly mentions it, one should use the "uninstall" button within the application to deinstall it otherwise he'll be left with a few invisible files on his system that contribute to the issues mentioned by some users here. I had a question regarding the license transferring procedure and received an appropriate answer from their service customer in less than an hour. KeyLemon might non be the bullet-proof protection for your Mac but for your daily needs and its simplicity of unlocking a computer by face recognition nothing comes even close to it.

The folder, .KeyLemon, is, somehow, AGAIN, back, as an invisible folder, in my Shared Folder, whence it magically locks my computer screen into Sleep mode. This time, I'm trying Secure Empty Trash. Maybe that will eliminate this final trace of a very-dangerous app.

THE APP THAT REFUSES TO DELETE! Well, I don't know what to say. Despite everything that I've done, KeyLemon is STILL installed and loaded on my iMac. I have AVOIDED letting KeyLemon get a picture of me. Hence, all that I need to do is to type in my password in order to unlock the screen. But, WTF?!

Seems like the program is quite stubborn. Have a look at the following Forum Entry. Maybe it'll help you.

In Lion 10.7.2, I have thrice successfully found an invisible, .keylemon folder that KeyLemon had installed into the Share folder in Drop-fxcking-Box, for God's sake! I use an old utility from '08 called "Find File," which you can find here on MUd. Even though you can't see the file on your Desktop, you CAN see it in FF's window and you can drag it from there into the trash. BTW, this invisible folder alone has all of the code necessary to re-install KeyLemon without your even knowing it it will lock you out of computer just as surely as the full installation does! And it does it from inside DropBox! It even has the power to resurrect itself TWICE from a Secure Empty Trash!

I'm not really sure that re-installing the entire app IN THE HOPE of deleting one folder, now that I've found a work-around for finding ot and trashing it - even though I've had to use it three times.

Jesus rose from the dead once. KeyLemon has done it three times! It's a hydra. You cut its head off and it grows another one. One that you can't even see and don't even know is there! Until you come back late from lunch and your screen is locked and your password won't work, because KL displays your usual name, but it has itself keyed to your "short" name! Pretty damned clever! Even though I nearly went into cardiac arrest, by the time that I was able to figure that out. Further BTW, KL works, whether you let it have a picture of you or not.

KeyLemon is definitely NOT child's play.

I think that this developer, if he ever gets its shit together, has a real future in the security field! But, his app is NOT for the rest of us!

Thanks for the suggestion, anyway, MacJ. I appreciate your thoughtfulness.

Dear users,

In order to uninstall KeyLemon correctly, please use the "Uninstall" button from WITHIN application, as explained during first step of installation.

Simply removing the application does not uninstall KeyLemon correctly. You have to use the uninstall button. Please take a look at the topic "How do I uninstall KeyLemon correctly" on our FAQ:

I thought that I had found and removed every trace of keyLEMON from my hard drive a month ago. However, today, I left my iMac unused long enough for it to go to sleep.

When I tried to awaken it, I was shocked to discover that I was Locked Out! By KeyLEMON!!!

To makes an annoying-long story short, Find File located yet ANOTHER KeyLEMON folder! This time, in my otherwise totally-unused Sharing folder.

Before, I'd been able to use Find File to delete the various pieces of KL, whether they were invisible or not, as well as to find them. This time, that didn't work. I had to use yet another app to turn on Show Invisible in order to find this particular .KeyLemon folder, shitcan it by hand, and then turn Show Invisible off, again.

If an app installs invisible files and folders ANYWHERE on your hard drive, then an uninstaller is an absolute necessity. It should never be harder to uninstall an app than it is to install it.

I downloaded and installed KeyLemon but something went wrong and KL wouldn’t work for me.
Then, I tried to uninstall it but the .Keylemon file, being invisible, couldn’t be deleted by me.
I contacted the developer and he stayed with me through many emails and suggestions ‘till I was finally able to successfully delete the recalcitrant file.
High marks for the developer’s support; it was truly outstanding. I didn’t get to try out KL but I got a good sense of the developer’s high integrity and sense of ethics.
Don’t think that I’ll try KL again because of the difficulty that I experienced uninstalling the invisible file but then, your mileage may vary.

Clearly, you chose not to heed my warnings. I specifically noted that there is no simple way to delete this app, if you decide that you don't like it or don't need it.

@Longboy
In my case it was not a disaster since I was not locked out of my machine at any time.
After attempting to delete the invisible file a number of times I double checked using EasyFind and Find Any File and found that the file kept remaining.
But by staying in contact with the developer I finally was able to resolve the issue.
At no time was my machine's operation compromised in any way.....it was just a pain in the ass getting the file deleted, although with the developer's assistance I finally managed it.

"At no time was my machine's operation compromised in any way."

ganjali, you were very lucky. When I tried the to use the previous version of this, a complete erasure of my HD followed by a full re-install was necessary, This version I didn't try to use. I merely downloaded it and - foolishly - opened it. I used an old-but-siill-working-in-Lion app, Find File, to locate and delete the files.
The first time, I couldn't contact the developer because my machine had been rendered inoperable. The second time, I didn't need to contact him, because the solution was obvious.
I still say that ho app should be posted that's not foolproof and/or has no uninstaller. KeyLemon is not foolproof and it has no uninstaller.
I'm an old-school Mac user. I'm not interested in any app that presents a challenge, unless it's a game.

Great app! It's not of course for a high secure protection of your computer but it's very convenient to protect my Mac and unlock quickly from standby.
Recognition improve a lot since v2.5 and multi-model support

If "it's not of course for a high secure protection of your computer," then there's no reason to take a chance on this. There's no point to low secure protection of your computer.
Besides, any app that installs invisible files, but has no uninstaller, is going to leave wth a major problem, you decide that you want to be rid of it.

I had installed this little nightmare but decided not to set it up. As has been mentioned here, KeyLemon is a real bitch to totally remove from one's system.
There's an invisible file but the developer's FAQ on how to remove the app doesn't work for me.
I'd say that the developer is very irresponsible in NOT warning the user that the app trial installs an invisible file that's not easy to remove. I'm currently trying to find a way to easily remove the offending file but have, so far, failed.

I installed this little nightmare but didn't set it up, yet whenever I log in to my Mac the Keylemon panel appears asking me to enter my password.
There's a Data folder that appears empty because it contains an invisible file.
It's a real bitch to completely uninstall this app.
I'd say that the developer is totally irresponsible for making the trial download
difficult to uninstall (and without warning the user before hand).
I didn't find the FAQ at the developer's website regarding uninstalling Keylemon terribly helpful.
