Logout, sleep, and secure trash empty

When securely emptying trash, the system goes to sleep, then tries to log out if the system is left unattended while trash is securely being emptied. When I go to wake the system, I have to log in (expected from reading other threads); however, the secure trash emptying prevented finder from quitting (the "Finder can't quit becaused some operations are in progress" and the "Trash" emptying window still active diolog window appears after relogging in) and the login items closed during the logout do not reopen after logging in. Energy saver is temporarily set for the system to not sleep due to a very large amount of files that need deleting.

Open the Security & Privacy pane of System Preferences and turn off automatic logout.

Regular and Secure Trash...

Hi, all.
What is the real difference between just "Emptying" the trash and "Secure Empty" it ???
I tried to find info, but found nothing.
Also, in the trash window, it always shows the option "Secure Empty". I remember in Tiger that the default was just "Empty"
How do I change that trash default in Leopard to be just "Empty" (not secure) ???
Thanx !!

Empty trash just unlinks the "file" from the space on the disk where the file is physically located. This allows other files to be written on top of the data on disk. Secure erase will write either zeros or random garbage to the data as well as unlinking the data from the "file".
In the finder's preferences (Finder Menu --> Preferences) in the "Advanced" section you can select whether or not to have secure empty trash be default.

LMS 3.2.1 on Solaris 10 - Setup Center / System and Security Settings Empty

Hi All,
When I get to the LMS Setup Center / System Settings option I can a screen that shows no options. The same happens when I try the Security Settings option.
I've attached a capture of the screen.
Thanks,
Jose Ribeiro

We're starting to see more and more users install on Oracle-branded Solaris. There is a workaround to installing on newer Solaris. You can modify /etc/release, and remove the word "Oracle" from the release name. Install LMS, then restore the original file. We're still trying to get an official word from development as to what our Solaris support plans are.

iMac Sleep Problem Waking - Screen Black & Pixelization
Have a new BTO 27" iMac I received a couple of weeks ago. Of course it is running Lion 10.7....
I am having a screen problem "waking" my iMac. (I also have this problem randomly on my MB Air - mid 2011 model)
After the iMac is in true sleep mode
(I have it set to enter a password after sleep mode)
Screen is blank/off
I "wiggle" my mouse or trackpad
Screen is still blank (sometimes it may display my screen saver, but the screensaver is frozen)
If I start moving the mouse or trackpad, it starts "un painting" the black screen. You can see whatever is supposed to be on the screen, such as the logon "button".
It is really wierd. Like a black "overlay" is painted on the resume from sleep screen. As I move my mouse or trackpad, it is basically erasing the black, to show what is underneath. Each movement of the mouse, erases a small black square.
I usually move my mouse around the middle of the screen to uncover the logon button. Press the logon button. The screen magically reappears as normal. I enter my password and system logs back on normally.
It only seems to be when the iMac is in really deep sleep mode. If the screen is just blank for an hour or so. I move the mouse/trackpad, and the logon screen is immediately displayed normally.
Any thoughts or recommendations?
Thanks to all in advance.

Still experimenting.
If certain programs are running (ie Firefox), then I don't have a problem coming out of deep sleep. It gives me a message when I reenter my password, that Firefox prevented the system from logging off.
Does that additional information help? It is a really annoying problem. And since I have it on my MBA, I am concerned it is more widespread. Does anyone else have this issue?

Black Screen and "Erasure" with Mouse.
I am having this same problem. I am using the Mac OS X Lion 10.7.2, not using a screen saver, and it happens sporadically upon trying to wake my iMac from sleep mode. The screen is black, and as you move the mouse over the screen, it "erases" the black, like the opposite of a blackboard, to reveal the login name and picture underneath. After that everything works fine. There is no pattern to this that I can discern (e.g. - happens every fifth time, only happens when a program isn't running etc.). It appears random, but is uber annoying, and behaves like a virus. I have Norton Antivirus, and it updates daily, and upon scanning states no virus is found. I also do system scan with MacKeeper, and it scans, says system is excellent. Something is definitely going on, I just wish I knew what it was. If anyone has any knowledge of this, any solution or insight would be greatly appreciated! Thanks!

That's because there are no Mac OS X viruses. You should uninstall Norton. You don't need 3rd party antivirus apps to protect your Mac from malware. Macs are not immune to malware, but no true viruses exist in the wild that can run on Mac OS X, and there never have been any since it was released 10 years ago. The only malware in the wild that can affect Mac OS X is a handful of trojans, which can be easily avoided with some basic education, common sense and care in what software you install. Also, Mac OS X Snow Leopard and Lion have anti-malware protection built in, further reducing the need for 3rd party antivirus apps.

You don't need MacKeeper, either. You really don't need "cleaner" or "maintenance" apps to keep your Mac running well, and some of these apps can do more harm than good. Most only remove files/folders or unused languages or architectures, which does nothing more than free up some drive space. It will not make your Mac run faster or more efficiently, since having stuff stored on a drive does not impact performance, unless you're running out of drive space.
Mac OS X does a good job of taking care of itself, without the need for 3rd party software.
Your problem, and the OP's is a graphics problem, likely having to do with the screensaver, not a malware problem.

Norton Antivirus, and what does it mean?
I suppose one reason I developed a concern that there was more here than meets the proverbial eye, so to speak was a message that I have received through Norton on multiple occasions. The last message of similar stated messages reads as follows (Norton Antivirus 2.2.1 (5) ): "Vulnerability blocked, December 13th, 2011, 8:57 P.M. When I click on "View Recent Activities", a window is opened that is titled "Activity Log." There, four columns are listed, titled from left to right "Date", "Event Type", "Result", and "Details." Under the December 13th episode, It lists "Portscan" under Event type, "Result" gives an IP Address (192.168.x.xxx), and "Incoming" under details.
I am admittedly a neophyte in the Mac world, having switched over from Windows 7 to Mac recently, but am intent on educating myself to the not-so-subtle differences. The above information that Norton displayed would lead one to believe that their antivirus software is protecting my iMac, and that its subsequent removal would have perhaps disastrous results ( i.e. - my iMac would be susceptible to said "Vulnerability", whatever it is, and that "Incoming would NOT be blocked). I had a conversation with Norton because previously, every time the stated "Vulnerability" attempted access, I was interrupted by a pop-up screen informing me of this. The Norton representative was able to turn off the pop-up screen notification, but stated that it would continue to log episodes of the "Vulnerability" when it attempted to portscan and access. So am I to understand that uninstalling Norton would leave my computer no less vulnerable to this vulnerability? It is confusing to me.
Furthermore, I suppose I did wonder if this vulnerability threat had anything to do with the issue of the black screen erasure with the mouse. I will attempt to post a picture of the screen as it was being erased with the mouse, and perhaps a short movie as well. As previously stated, I do not have a screen saver enabled. Thank you for your input, any information is helpful to me! _

Ditto & FYI Workaround
UncHeel...
Thanks for posting the picture. It is same as my iMac problem. On my iMac, it happens 100% of the time. On my MBA, it happens randomly like yours.
I began to notice if certain programs were running, when it went into screen saver and sleep mode, this didn't happen. And when I woke it up, I got a message that said "could not be logged off due to Firefox or Sketchbook Pro, etc. So that got me to thinking. So....
Over the weekend, I disabled "logoff after xx minutes of activity" in system preferences. That seems to fix the issue. I still have it set to require a password after the screen saver/sleep mode kicks it. But I disabled the logoff toggle.
Still not sure what this is an issue, but seems to be a work around. I just want to make sure my iMac is still going into sleep with these new settings. Including the monitor sleep.
Any thoughts based on this new information?
Thanks again
Greg

You have to remember that many antivirus apps consider cookies to be a "vulnerability" or "threat", when they're not. The only malware in the wild that can affect Mac OS X requires the user to actively install it. As long as a user is reasonably careful about where they get software, there is no need for 3rd party antivirus apps to protect Mac OS X from malware. Just make sure your firewall is enabled (System Preferences > Security > Firewall), and disable Java in your browser (Safari > Preferences > Security > Enable Java (uncheck))

You can let it sleep without logging off. That way, your apps/documents are still open when you wake it up, rather than having to relaunch apps and reopen documents. Recovery from sleep is much faster than from logging off.

I have had the same problem on my mid-2010 iMac since upgrading to Lion and it's been driving me nuts. The relation to automatic Logoff makes sense to me now that I look at my settings. The logoff was occurring after sleep and it's the only thing I haven't tried yet. I had previously thought it was related to Sleep but it never occurs if I force it to sleep. It only occurs after the system was left unattended and went through it's normal steps of screensaver then sleep. I'll try disabling the automatic Logoff and see if it fixes the problem for me too.

I can only declare partial success with unpicking "logoff after xx". It solved the pixelated screen issue but now the computer is not sleeping. I guess I'll have to uncheck file sharing now.

Just wanted to see if there had been any changes since the last posting in this thread. I'm experiencing the same issue as OP on my 2011 13" MacBook Air w/ OS X 10.7.3, as well as on my parents' mid-2010 iMac (running OS X 10.7.2).
I can't seem to pin down the cause and have tried the steps suggested previously. Thanks!

Still having the same issue here as well.
Have any of you tried a clean install of OSX?
Before I try a full reinstall I did an install on a external drive with no aps, just the bare install and I could not replicate the issue.
I continue to question if this is a graphics card firmware issue or and OS issue.
A reinstall (overlay) of the OS did not resolve the issue.
I have screen shots as follows:
1) Paint pixels on screen

Having the same issue
I have four MacBooks and a MacBook Air. I am seeing this issue on two MacBooks both running Lion 10.7.3. One is a newer i5 MacBook the other is an early 2010. The only common denominator I can think of is they are both set up with Parental Controls and they are set to logoff after X amount of time. The other MacBooks don't have this "pixel painting to revel the login screen issue" I also don't see it on our iMacs or the MacMini. Only the two with the issue are set to auto logoff. So the above poster is most likely on to something. I will give it a try by turning off the auto logoff on the two MacBooks in question. If that solves the problem then I will assume its a bug that needs to be addressed.

wchp - Thank you for following up and posting the screenshots. They match exactly what I was experiencing (and what UNCHeelYeah reported previously). I can confirm that I experienced the issue even following a clean reinstall of Snow Leopard on my MacBook Air (13-inch, Mid 2011).
jrobin - "I will give it a try by turning off the auto logoff on the two MacBooks in question. If that solves the problem then I will assume its a bug that needs to be addressed."
Good thinking! Thanks for taking the time to test with your machines. This will help provide further validation of what gswilder (OP) tried as well in reply #6. Interesting about Parental Controls, too.
Side note:
Since I recently joined the Apple Developers program, I did a clean install of SL on my MBA then upgraded via the App Store to Mountain Lion to "kick-the-tires" if you will. Interestingly, I've not yet experienced any issue related to waking from sleep with a black screen and pixilation, even while running all the same apps I had previously. I'll report here (and file a bug report with Apple) if I do see this issue pop-up in ML. I'll be reinstalling SL in a few weeks and will report back if/when the black screen and pixelation issue reappears. I'll be sure to note the applications left running at the time the computer went to sleep.

I have experienced the same issue with my brand new MBA Late 2011.
I recently found out that this only happens when DISPLAY is set to go to sleep minutes before the "Log out after X minutes of inactivity". I had "Display sleep" option set to 5 minutes and "Log out after 10 minutes of inactivity" and this causes the display to go to sleep first (screen goes black) and then, 5 minutes later, it logs out.
If "Display sleep" is off and "Log out after X minutes of inactivity" is on, the issue does not replicate. So Im thinking it has something to do with the screen being black at the moment it logs out. Can you try and replicate that?
Thanks

Just tested this premise and yes, you are correct.
IF: Screen saver ON after 5m AND require password immediately AND Sleep (Display) after 30m AND Logout after 60m I am able to reproduce the problem.
IF: Screen Saver ON after 5m AND require password immediately AND Sleep (Display) after 30m AND Logut after xx NOT enabled, problem goes away
IF: Screen Saver ON after 5m AND require password immediately AND Sleep (Display) OFF AND Logut after 60M enabled, problem goes away
So on my machine (iMac 27, 3.4/i7, 16GB/1333, Radeon 6970m/2048MB, OSX 10.7.3
It would appear that if I am running Monitor Sleep and it kicks in prior to LogOff then I am able to reproduce this artifact. Only Display sleep with immediate login OR Loguot should be used but not both.
The only other thing to test is is I leave display sleep on, and screen saver on but with NO immediate password and enable logoff if the problem goes away.
Testing for another day.
I have linked this entire thread to a Apple support ticket and will report back on Apples response

Thank you so much wchp, this is brilliant. I have had this annoying problem for a long time. I eventually rang Mac support, they did not know how to fix the problem as you have suggested so they instigated many hardware replacements which eventually left my iMac severely crippled. They eventually replaced it with the latest model. But I spent two months working with a disabled computer which really interfere with my work.
Your solution appears to have solved my problem, at least so far, but I am hopeful that it is a permanent fix. I hope that your suggestions are taken up by Apple support. This may solve many users problems and avoid Apple making expensive fixes that don't actually work.
I thought that the new iMac would not have the 'Wake up from sleep by painting in the login window' problem but it did, this really annoyed me. Anyway now the problem appears to be solved, it's not I will repost and keep working on it. Thanks again.

I accidentally hit the stop (x) button when the "empty secure trash" process was going on. Have I screwed up my computer? Can I continue the "Empty Secure Trash" later?

I was cleaning my caches which was taking forever to clean up. (more than 4 hours). I accidentally hit the stop (x) button when the "empty secure trash" process was going on. Have I screwed up my computer? Can I continue the "Empty Secure Trash" later?

Just restart your computer. Then go to Finder menu and change 'Secure empty trash' to Empty trash.
Unless you work with state secrets you really don't need secure empty trash which takes seven times longer to do its job. Empty trash is fine for all but the afore-mentioned secret files.

I have 74k photo's in my iPhoto trash and crashes when emptying. I have tried deleting the com.apple.iPhoto.plist but still won't empty.

Hi! I have 74k photo's in my iPhoto trash and it crashes when trying to empty. Clearly it's too much for the system to handle so after researching I downloaded 'Trashit!' which didn't help even if I selected one photo and dragged it to the trashit icon, not a single photo will delete from the iPhoto trash.
I've tried creating a new album but the photo's won't drag. I have tried deleting the com.apple.iPhoto.plist and done several timely rebuilds but I still can't find a way to empty the trash. I hope there's something really simple I'm missing here, any help appreciated

iiPhoto is known to lock up if you try to delete a large number of photos at a time. Here are a couple of ways to get out of the predicament you're in:
1 - go into iPhoto's General preference pane and uncheck the Show item counts checkbox:
and then try emptying the iPhoto Trash bin again. It's iffy however.
2 - If that fails and you don't use the Rating stars you can do the following: select all of the photos in the trash and Control-click to bringup the contextual menu. There will be the 5 stars for the ratings. Select either 5 or 1 to apply that rating to the photos.
Next create a smart album with the criteria:
selecting the number of start you applied to those in the Trash bin.
Move the photos from the Trash bin to the Library and the Smart Album will immediately be populated with those photos.
You can now select about 100 photos or so at a time and use the Command+Option+Delete key combination to move them back to the Trash bin and empty it. Repeat with groups of about 100 or so photos till they are all deleted. Then delete the Trash bin in the Dock to completely remove them from your hard drive.

if you use time machine, you should be able to get it back that way. Although IBA saves changes on an ongoing basis, it doesn't create a back up or supplemental copy elsewhere on your drive.

Ok. Add me to the moron list. I guess I am an over zealous trash emptier. Can I retrieve those images from the vastness by entering my time machine and restore the library from a previous date (when I wasn't a moron?)
