Log in screen appear after Mac goes to sleep even if screen lock is turned off.

Log in screen appear after Mac goes to sleep even if screen lock is turned off. This happens usually but not always. Using Yosemite, 2 year old iMac. This has only started to occur recently and it happened in Mavericks also.

Howdy stkh,
You may want to check the General pane of the Security & Privacy System preferences to make sure that the Require password...after sleep or screen saver begins is not checked. See this article for reference -
OS X Yosemite: General pane of Security & Privacy preferences
Thanks for using Apple Support Communities.
Best,

After upgrade to Lion, iPhone won't charge after Mac goes to sleep

I did a clean install of Lion, and have run Software Update. There are no problems with the system, but I noticed that when I plug the iPhone in to the Mac, it won't charge when the Mac goes to sleep.
The iPhone gives the normal charging tone when it gets plugged in, and if I l press the Home button, it displays the charging screen. If I select Sleep from the Apple menu, the Mac goes to sleep and the screen on the iPhone blinks on as if not plugged in, showing the normal unlock screen. When I wake the Mac, the phone beeps and shows the charging screen.
Is there a setting I can change to get the iPhone to continue charging after the Mac goes to sleep?

This behavior is new in my experience, having been on Snow Leopard. I've always just plugged the iPhone into my keyboard since it is very convenient, and it has always charged overnight, even while the Mac slept. So this is not normal behavior for my system.
My question is, has this changed in Lion?

Why does my screen freeze after it goes to sleep?

I have a Mac OS X Lion version 10.7.4
If I don't shut down my computer after each use and it goes into sleep mode, when I return the windows are frozen and when I move the mouse around, it blanks out the screen.
I have been able to figure out that pushing the "help" key on my keyboard, will stop the mouse from blanking out the screen wherever it moves across, however, all the windows remain frozen and I cannot click on anything even to try and shut down my computer. I have to shut it down by using the power button.
Once I restart my computer it is fine, but this problem will reoccur whenever it goes into 'sleep' mode.
Any help here?

I have been having the same problem with my MacBook Pro -2010 though. It just started a few weeks ago; can't seem to get the to screen stay on long enough to log back in; it goes back to black within seconds. I have tried all the different buttons; esc works sometimes after holding the power button down for a few seconds. Eventually the log in screen [or the screen I was at when I closed the top] will come back on.
I hope I can find the answer to this as I can't afford a new machine right now. Besides, it's only a year old but out of warranty.

Mac goes to sleep even when streaming to Apple TV?!

Hello everyone,
I just recently bought the Apple TV (3rd gen) to compliment my rMBP and am loving it.
I keep iTunes open with my Mac on, especially when I know I'm going to be streaming. However, my Mac seems to doze off half way through streaming a TV show, or a movie (usually something with a long play time). Macs have always just connected and "worked" for me so it seems strange that the ATV wouldn't just wake my Mac when I select Home Sharing.
If the show stops playing, sometimes if I go back and select Home Sharing again it will wake my Mac.. but often I get this message:
"Turn On Home Sharing in iTunes
To access your iTunes library on Apple TV, turn on Home Sharing in iTunes on your computer using <email>."
My Mac's energy savings are set to sleep after 1 hour, it's always plugged in. iTunes is always open. Do I have to set energy savings to 'always on' if I want it to serve the ATV whenever In want? I thought the ATV would be clever enough to wake the Mac when it wants something, which would save a lot of energy - and as I said it does work on occasion. As I have a connected USB hard drive I'm trying to do it this way instead of having an always-on NAS.
I should probably add that I'm using an AirPort Extreme with the correct firmware required to have the whole wake-over-wifi stuff.
Advice please :o)

seems to be a bug. What I have done is set my computer to necer sleep and the display to sleep after 3 mins
This way the Apple TV works but I do not have a bright Computer system shining at me while I am watching TV

Request to Mods. re: Yoga Tablet pro 2 not wakeable after it goes to sleep

We have a number of posts regarding the Yoga Tablet Pro 2 going to sleep and not waking up. Can we get some kind of confirmation that this is actively being worked on or passed along? I feel most of us have tried to do a factory reset, for some it's worked for a time, others (such as myself) this has not worked at all. It is not a battery issue because when you hard power off the device and repower it back on, the battery still shows maybe a few percent less than when the device went to sleep.
I do know this is frustrating me and I'm tempted to walk away from this tablet for that reason.
Perhaps we can get a confirmation that this has been passed up the chain or any kind of other "official" recommendations to try. It's not fun having to come back to my tablet after it goes to sleep and having to hard power it off and then repower it back on - every 5th or 6th time.
Thank you,
Dan

I am bumping this. I'd like to see one thread or a sticky on this topic. There are too many threads on this issue and some of us are repeating the same information. I'd also like to know if any work is being done by Lenovo on this issue. The Factory reset seemed to work for a 2 weeks and now my tablet is back to sleeping and not waking.
If someone stumbles on this, the North American Number for Lenovo Tech Support is:
877-453-8686
If you call, Remind them that the Factory reset does not work.
Dont forget to be courteous!

Screen sharing from OS X to Linux: No screen appears on Mac.

I am trying to connect from my MacBook to a Linux machine on the same subnet to see the Linux screen on the Mac. I press the "Share Screen" button in Finder under the remote desktop icon that appears in the Shared section of the sidebar and the Linux machine instantly tells me that another computer is controlling its screen. However, on the Mac, there is only a dialog box saying "Contacting xxx's remote desktop on yyy" and no remote screen appears.
I have traced the VNC packets (via Wireshark on the Linux box) and output is as below. IP ending in 140 is Linux, 150 is the Mac. Both machines are hardwired to the same switch.
4.707835 192.168.5.140 192.168.5.150 VNC Server protocol version: 003.007
4.708132 192.168.5.150 192.168.5.140 VNC Client protocol version: 003.889
4.708907 192.168.5.140 192.168.5.150 VNC Security types supported
4.709148 192.168.5.150 192.168.5.140 VNC Authentication type selected by client
5.131544 192.168.5.140 192.168.5.150 VNC Authentication result OK
If I try to go from Linux to Mac, the Mac sends its server protocol version then kills the connection.
I can happily share the screen of a Windows XP box on the same LAN via the Microsoft RDP product.
I am new to the Mac, can anyone please help?
Peter.

Greetings,
I have the Apple remote desktop working from the finder, its just as fast as any other vnc package I've tried and more convienient that chicken of the VNC or others as it is available from the finder. The configuration details below also work with chickend of the VNC and vine viewer.
I have a Mac OS 10.5 machine and a Linux centos 5 machine on the same network at home. The Linux machine is headless ie, no monitor, mouse or keyboard and my goal was to get the Apple remote desktop working to the Linux machine so that I could login and get a gnome-session desktop. I ran into the issue you describe and solved it after making the following configuration changes on the CentOS 5 machine.
On the Linux machine it is assumed that all the gnome desktop packages are installed and that you have the vnc-server.i386 package installed from the yum repository. avahi.i386 and avahi-glib.i386 are also installed. xinetd must also be installed from yum if you do not have it. xinetd.i386
I. Enable zeroconf avahi service ie, bonjour so your apple can see the Linux box in the finder.
a) If you can see the Linux machine in the finder, perhaps you already have the avahi daemon configured properly, otherwise edit /etc/avahi/avahi-daemon.conf. Mine looks like this, where mylinux_boxhostname is the actual hostname of my machine and browse-domains is a comma separated list of domains that I use:
[server]
host-name=mylinux_boxhostname
#domain-name=local
browse-domains=local, mydomain
use-ipv4=yes
use-ipv6=yes
#check-response-ttl=no
use-iff-running=yes
enable-dbus=yes
#disallow-other-stacks=no
#allow-point-to-point=no
[wide-area]
enable-wide-area=yes
[publish]
disable-publishing=no
disable-user-service-publishing=no
add-service-cookie=yes
publish-addresses=yes
publish-hinfo=yes
publish-workstation=yes
#publish-dns-servers=192.168.50.1, 192.168.50.2
#publish-resolv-conf-dns-servers=yes
[reflector]
#enable-reflector=no
#reflect-ipv=no
[rlimits]
#rlimit-as=
rlimit-core=0
rlimit-data=4194304
rlimit-fsize=0
rlimit-nofile=30
rlimit-stack=4194304
rlimit-nproc=3
b. Add or edit the file /etc/avahi/services/rfb.service, mine looks like this, note the port setting is 5900, this is the first X display . So the apple remote desktop client will attempt to connect to display on the linux machine. Other possibilites are port 5901, 5902, etc... for different X displays on the Linux machine:
<?xml version="1.0" standalone='no'?>
<!DOCTYPE service-group SYSTEM "avahi-service.dtd">
<service-group>
<name replace-wildcards="yes">%h</name>
<service>
<type>rfb.tcp</type>
<port>5900</port>
<txt-record>No User Authent0</txt-record>
</service>
</service-group>
c). Restart the avahi daemon on the linux box:
# service avahi-daemon restart
II. Configure the gdm gnome display daemon
a) My Linux machine is headless and does not have a keyboard or mouse. So, I disable display in run level 5 so that I may use VNC to connect to port 5900. Edit /etc/gdm/custom.conf. Mine looks like this:
[daemon]
RemoteGreeter=/usr/libexec/gdmgreeter
[security]
AllowRemoteRoot=false
[xdmcp]
Enable=true
[gui]
[greeter]
IncludeAll=true
[chooser]
[debug ]
# Note that to disable servers defined in the defaults.conf file (such as
# 0=Standard, you must put a line in this file that says 0=inactive, as
# described in the Configuration section of the GDM documentation.
[servers]
0=inactive
b) Restart X and gdm
# init 3
wait a minute or two and then
# init 5
III. Configure an Xvnc to start on port 5900, display from xinetd.
I'm using two monitors on my Mac, one monitor has a resolution of 1440x900 and I'm using it to display the remote Linux desktop.
a) The apple VNC seems to want a VNC password so I configure the VNC server on the Linux mahchine to use one, you can save this password in your keychain when you connect for the first time with the Apple Remote desktop client. Configure a vnc password owned by the user nobody on the Linux machine:
# vncpasswd /etc/vncpasswd
Password:
Verify:
# chown nobody:nobody /etc/vncpasswd
b) Create a vnc service under /etc/xinetd.d on the linux machine by adding the file named /etc/xinetd.d/vnc. Mine looks like this, note the vncpasswd location, nobody user, and screen resolution:
service vnc
disable = no
socket_type = stream
protocol = tcp
group = tty
wait = no
user = nobody
server = /usr/bin/Xvnc
server_args = -inetd -query localhost -geometry 1440x900 -depth 16 -once -fp unix/:7100 passwordFile=/etc/vncpasswd
c) Add the following to the end of your /etc/services file, mine looks like this:
# Local services
vnc 5900/tcp # vnc server
d) Restart xinetd
# service xinetd restart
III. Setup your user environment on the Linux machine.
a) we are logging in with the username foo whom has a password. User foo has a home directory at /home/foo. His .bash_profile is to his liking and he wants to have a gnome session.
b) Examine /home/foo/.vnc/xstartup. Make sure the file is executable. Mine looks like this:
#!/bin/sh
# Uncomment the following two lines for normal desktop:
# unset SESSION_MANAGER
# exec /etc/X11/xinit/xinitrc
[ -x /etc/vnc/xstartup ] && exec /etc/vnc/xstartup
[ -r $HOME/.Xresources ] && xrdb $HOME/.Xresources
xsetroot -solid grey
vncconfig -iconic &
gnome-session
c. Make the xtartup file executable:
$ chmod +x /home/foo/.vnc/xstartup
IV. Login using the Apple RDP from the finder as the user foo.
a) Make sure the SELinux firewall on your linux machine is not going to block port 5900. I disabled my SELinux firewall as all my machines are behind a NAT router with a firewall running.
b) If the avahi daemon is configured and working properly, you should see the hostname of your linux box in the finder window. Highlight it and you should see a "Share Screen" button. Push it. You will be prompted for the vnc password that we set on the Linux machine using vncpasswd. Enter the password and you should be able to save it in the keychain. Subseqent logins will not require you to enter it manually again unless it gets changed.
b) If xinetd and gdm above were configured properly, you should now have a gdmlogin screen at the resolution specified, mine is 1440x900. Login using the foo login and password. You should get a gnome-session desktop.
c) In case of trouble, try telneting from a term window on the mac to port 5900 on the Linux box. If you get Connection Refused, double check your xinetd configuration and/or any firewall ipfilters running on the Linux box.
Run netstat -an|grep 5900 on the Linux box. If you see a port LISTENING, then you have a firewall problem between the Mac and Linux box, xinetd is okay.
I have this working perfectly and use it to work from my Mac to the headless Linux machine every day.

My iMac logon screen locks up after it goes to sleep

my iMac log on screen locks up no mouse control after it goes to sleep when I turn it on by hitting the spacebar I have to reboot Iam running the latest softwear

Please read this whole message before doing anything.
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 in OS X 10.9 or earlier, or if a firmware password is set, or if the startup volume is 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.

Error after my Mac goes to sleep after streaming music?

After streaming music and stopping for a while, my Mac goes to sleep and I receive the error in the attached screen shot when I try to stream again. The only thing that seems to work is quitting iTunes an reopening. Why does it do this and how can I stop it from doing this? Thanks.

Hello Media Fred,
It sounds like you are getting this message after the computer wakes from sleep, and you need to restart the iTunes application to get it to work correctly. I recommend signing out of your account first:
Choose Store > Sign In (or Sign Out).
From: iTunes 11 for Mac: Manage your iTunes Store account
http://support.apple.com/kb/PH12299
Then restart your computer, and sign back into the iTunes Store and test the issue.
Thank you for using Apple Support Communities.

My sons ipod shows the apple sign and then occasionaaly a white screen appears and then goes back to the apple symbol.. He cant get it to turn on

my sons ipod shows the apple sign and then occasionaly a white screen appears and then goes back to the apple symbol.. He cant get it to turn on.. He has tried charging it.He also held down the sleep/wake button and the home button at the same time to reset it. we need help

Try:
- iOS: Not responding or does not turn on
- Also try DFU mode after try recovery mode
How to put iPod touch / iPhone into DFU mode « Karthik's scribblings
- If not successful and you can't fully turn the iOS device fully off, let the battery fully drain. After charging for an least an hour try the above again.
- Try on another computer
- If still not successful that usually indicates a hardware problem and an appointment at the Genius Bar of an Apple store is in order.

Hi I have used my macbook pro with miniport to HDM, and it was working fine. Hadnt used it for a month and now when I connect the TV, the screen on the mac goes blue then back to the page but nothing comes up on the TV. Any ideas?

Hi I have a year old Macbook pro. I was using a miniport to connect it to the TV via HDM cable. It was working fine but I have used it for a couple of months kept it in a drawer and now it doesnt work. When connected to the TV the screen on the mac goes blue as though there is some signal then back to original screen but the TV doesnt show what's on the laptop. Please any suggestions, thanks??

Hello nothingissecret
Check out the article below for troubleshooting steps to resolve the issue. One would be to try a different cable or adapter to test with the television.

Why does my iphone 3gs screen go white after it goes "to sleep" for the first time after turning it on?

Why does my iphone 3gs screen go white after it goes "to sleep" for the first time after turning it on?
The screen isn't broken because it works after i turn the device off and back on, but after it goes black once, it's only white again.
But it takes the touches although it's only white, because I can answer my phone when I slide my finger on the bottom of the screen, eventhough there in not the button to see.
This is so weird. I have already done everything I can think of that might help. But I cannot think of anything that might be causing it, because nothing has happened to the device.

Let me know if I should start a new discussion instead of opening a new topic here.
My wife's iPhone is the same vintage as mine 3Gs, but has never had the battery problem. Its affliction instead is that it cannot detect WiFi networks unless it is quite close to the source. Often, when my iPhone not only detects but shows a maximum cells connection with a network, hers cannot detect the network at all. In contrast, her iPhone seems to detect ourcellular carrier just as well as mine does.
Is there any help for this affliction?

There is always a blue screen appears after the Apple logo during the booting process. And then everything is back to normal. What is this thing? Is there something wrong with my screen or something?

Try using Disk Utility to do a Disk Repair, as shown in this link, while booted up on your install disk. You could have some directory corruption. Let us know what errors Disk Repair reports and if DU was able to repair them. This could just be a start in repairs and you may need a better utility to finish the job.
Then Repair Permissions.
No need to report any Permissions errors........we all get them.

My mac won't recognize an external monitor. The screen Goes Blue Once, then goes blue again and the second monitor just turns off. I am using an HDMI adapter to a visio TV. I also have my xbox on the tv. Can anyone Help??

Lol, figured out the first part. Just for those who may be searching, when you click on the Display Preferences, and click on the arraingment tab... it not only shows where your two screens will be displayed, but the WHITE BAR at the top of one screen is the dock/toolbar. Click and hold to grab this and just slide it over to the screen you'd like it to be on.
You have to release it IN the screen box, not on top of it... and it should pop right over to the new (or old) screen. At any rate, you can put the dock on either (or any) screen that you prefer.
I am thinking of ordering more of these. Lol. 3 monitor setup seems like it would be crazy good.
Still looking for the answer to keeping the new 16" screen on the right without switching between screen #s with that... not expose... Lion feature.
Thanks. Hope my other question has an answer out here.

what can be done?

Theres no issue with the mother board. It's the activation lock look at the link I provided.
There is nothing you or Apple can do without the previous owners icloud information.
Like I already stated you have a paperweight.
