System becomes unresponsive (hang) on exit from screen saver

subject line says all, frequently when exiting from the screensaver (type in password and hit enter) the system becomes un-responsive (hang). Any ideas ?

Are you using the stock Arch kernel or some other one?
What's the output of 'cat /sys/block/sdb/queue/scheduler'?

Resume from Screen Saver Issues

Hey All,
Well...migrated from Leopard to Snow Leopard with minimal issues but
In Leopard, after waking from screen saver, a box would prompt for a password. I've gotten SL to do this, but there is no way to switch user.
I have multiple users and i'm unable to switch users from SL.
Any ideas??

I try to solve it,
but it dose not any effect.
Now I will updating OS X to v10.10.3

right, i'd just like to add that this issue was solved by installing "proper" ati drivers, or lowering sync and refresh rates in /etc/X11/xorg.conf, one of those

OSX Mountain Lion Finder slowly dies, system becomes unresponsive - restart required to

I have a MacBookPro retina and it was working fine for months but all of a sudden its now started to fall apart every few hours. I use my computer daily for work and when i first boot up everything runs well but over time, say 2 hrs, i notice that screenshots take ages to appear on my desktop and then finder doesnt open and even new web pages or new applications do not load. I try restarting finder, but that doesnt help forcing me to restart my computer, which i sometimes need to force restart as it hangs on the grey screen.
Things I have tried that have not worked
- re-installing Lion
- removing the 'All my files' bookmark from finder
- uninstalled air display (which registered some 3rd party kernels)
I have noticed that my mac never finds my backup timecapsule, so i will try turning off timemachine entirely.
Help!!!
p.s. I kinda miss my 2009 Macbook pro with Snow Leopard, still going strong and has had a fraction of the issues i have experienced with my new retina and OSX lion combo.

Crashing after return from screen saver. MacBook Air late 2011 Lion

Hi, hoping to get some help from this community. I have a late model 2011 MacBook air running the latest version of OS X Lion. The last few months I've had an issue with getting a complete black screen with the squarely ball rotating and otherwise very little response but I can move the mouse around. The last time this happened, I was actually able to three finger swipe between desktops, but otherwise the system was unresponsive. This swiping between desktops eventually stopped also. Alt-tab also work as long as I was switching between desktops. While I can still scroll the cursor around the only way out seems to be a hard reboot.
My configuration is fairly standard, however I do have office 2011 installed and also Lotus Notes. Both are at the latest level, however I do realize this might be part of the problem. I am also using a VPN connection into work however this is a normal set up through OS X.
I'm trying to narrow this down to root causes. Any thoughts?

Boot into Internet Recovery (command-option-R at the startup chime) and try to repair the boot volume in Disk Utility. You will have to unlock the volume before you can do anything with it.

PowerMac G5 hangs after going into screen saver power save mode

I have a PowerMac G5 and it's been working fine, but as of late has been hanging. I had a couple of external disks on the machine ( Maxtor OneTouch II and a OneTouch III). I recently added two more OneTouch III and stripped the three OneTouch III's together in a RAID set. I'm wondering if that is causing the hangs, but I've also seen it hang without the RAID so I'm not convinced it's the RAID.
Anyway, I can't figure out what's causing it to hang, but it seems to hang at some point after the screen saver runs and then the screen goes into power saver mode. It's not hung right when it shuts down the monitor, but at some point after that.
When it gets in this mode, I can't remotely login using ssh and I can't seem to wake it up. What I end up having to do is to hold the power button down for several seconds until the machine powers off.
In an attempt to see what's going on, I set the OS X monitor power save mode to "never", but I don't think I left it that way long enough and I never saw it hang.
Does anyone have any debugging tips that would help me identify the culprit?

I've been having the same troubles lately. Seem
since the JAVA update. It hangs completely after the
screen is shut down. Every morning I have to reboot
with the power button.
I am also joining the crowd with this issue. I have a 15" Powerbook G4 that has acted normally until recently. Not sure exactly when it started, but about the same time as the recent updates. Similar behavior to the previous forum posts.
When I manually put the laptop to sleep it freezes up before it sleeps and the multi-language reboot warning comes up. This also happens if it is set to auto-sleep after xx minutes.
When I try to wake it up, the screen is black and the power light shows it is on and it never unfreezes or I get the reboot message.
I have tried everything I can think of to troubleshoot this. I just re-installed the 10.4.8 update over the exisiting one (using an external boot drive made with SuperDuper) and it still happens... BUT when I put the laptop to sleep with the startup drive being external, it seemed to behave properly. I can't figure this out since the external clone was made only minutes earlier from the laptop... and it works. I have zapped PRAM, and done the battery removal / power button reset.
Below is the "report" I have been getting - and sending to Apple. They must be getting tired of the many I have sent.
Any thoughts out there?
Thanks.

Apple TV unresponsive after 15 minutes in screen saver

Hi,
I have a 1 week old Apple TV. It works great until you leave the room. Then, after the screen saver kicks in for about 10 minutes, it will no longer accept commands from the remote.
The remote is unpaired, and I also tried my macbook remote on it, and that doesn't work either.
I have swapped batteries in the remotes, this didn't work.
The one intersesting thing is although I cannot get out of screen saver mode with the remote, I can hit Menu and - and reboot the apple TV.
The other issue is upon reset, it hangs on the Apple screen. The only way to succesfully reset is to unplug and leave it for at least 15 minutes.
What I have not yet tried:
1) Disabling the screen saver completely
2) factory reset

It was bought online through a third party retailer, so its not exactly as convenient as driving to the store. I'd rather exhaust my options before having to send it back.

MBP switches spaces when returning from screen saver

When I move my finger minimally across the touchpad to bring my screen out of screen saver, invariably my MBP decides to shift spaces to the next to the left or right.
It is annoying.

From System Preferences, go into Security. Hopefully, the padlock icon at the bottom will show as unlocked, because if it doesn't you need a password to open it to allow you to make changes. You will see a box that says "Require password to wake this computer form sleep or screen saver." That should do it. The password being asked for is your administrative password.

HUGE SECURITY HOLE IN LOGIN FROM SCREEN SAVER

One of the options in the security panel permits a user to require that a username and password be entered to login once the screen saver locks your account.
The option is "Require password to wake this computer from sleep or screen saver"
Although one would assume that the credentials required to wake the computer is the username/password of the account that was being used when the computer went into sleep mode or the screen saver. WRONG!!! Anyone with an account on the machine can enter their username/password and wake the computer and voila that user now has control of the machine as the former user. That's right you guessed it HUGE security hole.
Anyone thinking that they can wake away from their machine and have the screen saver or sleep mode protect their account after a specified period of time is sadly mistaken. Anyone with an account on the machine can enter their own username and password and drop right into your account right where you left off.
Can you believe this stuff? No warning, no release note to tell you of such a poorly designed "security" option.
Apple please fix what must have been an oversight or at least tell people about this intentional design BEFORE they find anyone can wake the computer and become you as a user.
Thanks,
JH

Anyone with a standard user account? Are you quite sure?

I never think that way. A more secure lock is ensured by using the screen lock feature of the keychain.
Can you believe this stuff?
Not sure what stuff you refer to.
No warning, no release note to tell you of such a poorly designed "security" option.
Would you believe that anyone can access your computer? Stolen computers are regularly started up without much problem.

You are writing to other users like yourself here, not Apple.

Missing password window when waking from screen saver

I've had some issues with waking from sleep once I turned on the screen saver password. I opened the lid and the screen lit up and I had the mouse pointer--but no user name/password box.
I tried opening/closing the lid a few times, plugging it in to an external monitor, etc, and no luck. I ended up having to hold the power key down until the machine turned off and then I rebooted, and I lost some work.
Is there any way to force a login screen?

I have a simple solution, go to your "Energy Savings" setting under the System Settings, once there move the slider-bar so that your screen saver is never activated. Now move the slider-bar so the system goes into "stand-by" mode after 5-10 minutes, thus once opened again, should prompt you to enter your password..?!
Please ignore the "Windows" terms. I'm a new Mac user, but this solution has seamed to work in my case, at least until a "Fix" is made.

10.9.4 not responding when logging in from screen saver

I have a MacBook Air with Mavericks and this wee I updated to 10.9.4. I have password activated restart from screensave; everything was normal but today, when I close the display and it sleeps, at the start screen I type my password and it freezes, it does not log in or does anything else, the dots showing representing the password go grey and ceases working. If I press the power button it restarts the login screen but after typing the password it does the same. If you type the wrong pass it shakes and says bad password so it responds to that but does not login.
If I force a restart, at the login screen it accepts the password and logs in but not after sleep or screen saver. Any ideas? I deactivated the password protected screen saver but it is not a solution, I hope you could help me.

This procedure is a diagnostic test. It’s unlikely to solve your problem. Don’t be disappointed when you find that nothing has changed after you complete it.
The purpose of the test is to determine whether the problem is caused by third-party software that loads automatically at startup or login, by a peripheral device, by a font conflict, or by corruption of the file system or of certain system caches.
Disconnect all wired peripherals except those needed for the test, and remove all aftermarket expansion cards, if applicable. Start up in safe mode and log in to the account with the problem. You must hold down the shift key twice: once when you turn on the computer, and again when you log in.
Note: If FileVault is enabled, or if a firmware password is set, or if the startup volume is a Fusion Drive or a software RAID, you can’t do this. Ask for further instructions.
Safe mode is much slower to start up and run than normal, with limited graphics performance, and some things won’t work at all, including sound output and Wi-Fi on certain models. The next normal startup may also be somewhat slow.
The login screen appears even if you usually login automatically. You must know your login password in order to log in. If you’ve forgotten the password, you will need to reset it before you begin.
Test while in safe mode. Same problem?
After testing, restart as usual (not in safe mode) and verify that you still have the problem. Post the results of the test.

Security problem: Waking from screen saver botched in 10.5.5

When using my MBP, I like to have my screen saver as simple computer lock in that it requires a password to wake the computer from sleep or screen saver (option in the Security system preference pane).
Since the update to 10.5.5, my computer just wakes from sleep or when in screen saver mode, without demanding a password to be entered, even though the option is checked in the pane. I did an immediate SMC reset after the installation because the fans were acting oddly, and a PRAM zap just now to see if it'd do any good with this problem.
Has anyone experienced something similar?

I had this happen a few times back when I was running Tiger. I was able to fix it by going to Homefolder/Library/Preferences/ByHost and deleting all of the com.apple.screensaver.xxxxxxx plist files, and then logging out/in.

Sign in from screen saver

I am having trouble with my Mac accepting my password from the screen saver. What happens is that when I enter my password into the screen saver it gets hung up and doesn't move past that point. Each time this happens I basically have to reboot my system. I use my Mac as a corporate machine so I'm assuming this is some kind of authentication problem with my credentials?

Fast User Switching From Screen Saver

How can I make my Mac display the login screen (as though I'd selected "Login window" from the fast user switching menu) after the session has been idle for a certain time?
I can make it log out after some amount of inactivity, but I don't want that. I want my programs to continue running.
I can also set the screen saver to require a password, and clicking the "Switch user" button on the password dialog will display the login screen. I'd effectively like to skip that step and go directly to the login screen without having to push the button.
note: I stole the wording of this question directly from here , which was posted 2 1/2 years ago. One solution then was to download a custom Script Saver and use a custom Apple Script, and the other was to purchase a 3-rd party product which costs $50.
The reason I want to do this is because I am setting up an iMac for a family with small children. The iMac will be shared by 4 people, and training the kids to click on the "Switch User" button is a hopeless task, so please don't suggest "train the users to click on the 'Switch User' button".
Also, this is not my computer. I want to keep the solution as simple and fool-proof as possible, becuase I don't want to get called if something breaks (which is why I'm disinclined to use a script or buy a 3-rd party product I don't trust).

PS -- Script Saver has been discontinued.
https://www.macupdate.com/app/mac/9599/scriptsaver
So that's not an option anyway.
