Screen freezing in Lion

Since upgrading to Lion, I've had to hard shut down (?) my computer more each day.
Is this a common problem or possible virus?

Sorry - I should have run through a few of the things I've tried:
Reset PR / NV Ram
Disk and file permissions check and repair and verify
Re-installed with 3 separate app store downloads
Installed from scratch
Bought a new HDD and installed it there so make sure it wasn't the disk
Memcheck
Everything unplugged for 25 minutes and then turned back on
Safe mode
SSH in from another computer
I spoke to Apple yesterday, they sent me an app so shovel over all the log files. Whilst doing that, I wrote a timeline of the errors:
12:39
Computer wouldn't wake from sleep, so had to hard reset (with power button). I've had this a lot as well.
12:41
Power on noise -> Apple logo with spiny
12:43
Login screen visible, light on Caps Lock key working, keyboard and mouse aren't functioning. This time, there was no grey flashing square.
12:51
Keyboard suddenly started working, all the characters I'd hit since 1243 came through. I logged in as normal
12:52
I clicked the notifications icon (top right). Nothing happens, the dock stops working, doesn't respond to mouse-over or click. Cmd-tab also doesn't work. Applications, spotlight, finder, etc all function as normal.
12:56
Notifications bar finally slides out, dock works again, and now clicking notifications icons works perfectly.
Thanks for the suggestions though Grant, sincerely appreciated.

Login Screen freezes after Lion 10.7.2 upgrade - needs 3 hard reboots

Just upgraded my 21.5" late 2009 iMac to OS X Lion 10.7.2.
0. Power up from cold start: login screen appears, and mouse works, but clicking on users does not bring up the password box. No option except for hard reboot.
1. Hold down power button until it shuts down. Power up, still no respponse (see 0.).
2. Hold down power button until it shuts down. Power up, still no respponse (see 0.).
3. Hold down power button until it shuts down. Power up, responds normally, can login (or start computing if login screen is bypassed).
I saw messages (mostly for MacBook Pros) dating back to July/August 2011 with similar problems. But none for 10.7.2, and none where it consistently takes 3 hard reboots to get a response. I tried all of the suggestions that applied: SMC reset, repair disk permissions, change password, bypass login screen. If I use automatic login, it boots up into my desktop and all the services seem to start. The mouse works, but nothing responds when I click on it (see 0.).
Any ideas?
thanks,
david

Thanks lynque. It turns out I did need a keychain repair, but that didn't fix the problem. I probably should have done this earlier, but I ended up unplugging all peripherals (2 firewire + 3 USB) then powered up without issue.
So I shut down, plugged in one at a time, and ran into the problem again after plugging in an external hard drive (WD My Book Essential). I repaired with disk utility, but the problem remained.
I then rebuilt the partitions with Disk Warrior, and now everything seems to work....

Mac OS X Lion Server screen freezes frequently

I have recently purchased the Mac Mini Server with 8GB RAM Upgrade and have been experiencing screen freezes frequently. The Mac Mini is connected to a ViewSonic LED Monitor via an HDMI cable and is running Mac OS X Lion Server.
It all started a month ago and I suspected it was due to an external hard disk I had. When I removed it the problem didn't crop up for a few weeks. So I thought the issue was resolved.
Over the past week the problem re-surfaced again and nearly everyday I am experiencing screen freezing about five times a day and the only option is to power down my Mac Mini Server from the power button. This is becoming increasingly frustrating. When screen freezing occurs, everything freezes and I get some small rectangular boxes on screen moving.
The only things that have changed over the past week was that I installed the latest Safari fix and connected the Harman Kardon Sounsticks II to the Mac Mini.
Can't understand what is happening. From various threads I read, many mac users are experiencing screen freezes. If anyone has any resolutions please let me know.

Lion has a screen refresh bug it is just the screen going to sleep and the the screen updating only where the curser moves.

Mountain lion screen freeze

Since I downloaded Mountain Lion OS 10.8, my screen freezes constantly. I wish I had never downloaded this "upgrade." Need solution ASAP becasue this puts me out of business.

If you have more than one user account, these instructions must be carried out as an administrator.
If you have an optical drive, make sure there is no disc in it.
Launch the Console application in any of the following ways:
☞ Enter the first few letters of its name into a Spotlight search. Select it in the results (it should be at the top.)
☞ In the Finder, select Go ▹ Utilities from the menu bar, or press the key combination shift-command-U. The application is in the folder that opens.
☞ Open LaunchPad. Click Utilities, then Console in the page that opens.
Step 1
Make sure the title of the Console window is All Messages. If it isn't, select All Messages from the SYSTEM LOG QUERIES menu on the left.
Enter "BOOT_TIME" (without the quotes) in the search box. Note the timestamps of those log messages, which refer to the times when the system was booted. Now clear the search box and scroll back in the log to the last boot time when you had the problem. Post the messages logged during the time something abnormal was happening. That time might be before or after the boot.
For example, if the problem is a slow startup taking three minutes, post the messages timestamped within three minutes after the boot time, not before. If the problem is a system crash or shutdown failure, post the messages from before the boot time, when the system was about to crash or was failing to shut down. In either case, please include the BOOT_TIME message at the beginning or the end of the log extract.
Post the log text, please, not a screenshot. If there are runs of repeated messages, post only one example of each. Don’t post many repetitions of the same message.
Important: Some private information, such as your name, may appear in the log. Edit it out by search-and-replace in a text editor before posting.
Step 2
Still in Console, look under System Diagnostic Reports for crash or panic logs, and post the most recent one, if any. In the interest of privacy, I suggest you edit out the “Anonymous UUID,” a long string of letters, numbers, and dashes in the header of the report, if present (it may not be.) Please don’t post shutdownStall, spin, or hang logs — they're very long and not helpful.

Screen freezes after login on Lion OS X (intermittent)

Ever since upgrading my MacBook Pro (purchased Apr-10) from Leopard to Lion I'm experiencing an intermittent problem where the screen freezes once a user has logged in. The problem only occurs when the machine is started from off and doesn't occur when starting from sleep or when switching users.
This problem affects all users set up on this machine and results in a cursor that can still be moved but can't select anything and a keyboard that is unresponsive. Most times the cursor shows as the coloured wheel. I have left the machine in this state for over 30 minutes to see if it would recover but it doesn't and I have no option other than to perform a hard reset by holding down the power button. Sometimes it can take a couple of hard resets before the machine recovers.
The configuration of my machine is fairly straight forward with an Apple Time Capsule providing backup and WiFi and minimal software installed.
I have found that disabling all 'Open At Login' apps reduces the likelihood of the problem but doesn't cure it.
Has anyone else experienced this problem and can provide a solution as I want to avoid having to revert to Leopard if possible.

Accelerated Video Drivers for the 5770 and 5870 first appeared in 10.6.5, so when running 10.6, be sure to update to at least that version before drawing conclusions.
Otherwise, I think your conclusions that this is a graphics card problem are likely correct. Over a very large sample, these cards have been much more reliable than many previous cards. But you do not have a very large sample, you have one card.
The Mac Pro (65lb tower) uses Error Correcting Code memory, so this is NOT a RAM memory problem or you would be getting kernel panics with machine check, uncorrected error.
Apple hardware test is a tool that only seems to detect the grossest of errors. It is famous for false negatives.

OS Freezes since Lion Update

Ever since I upgraded my MacBook Pro to Lion, it has been freezing the entire system on startup.
I can move the cursor, but I can't click on any files, folders or bars.
I end up having to do a hard boot of my laptop and try again.
I know it isn't because of system requirements, because i have a Core i7, 8GM RAM, and a 1TB hard drive (with 700GB free).
I don't have any apps that load on startup, so it can't be that (unless Lion added soething).
Anyone else have this problem & or know how to fix it?
cheers,
X

I am experiencing the precisely the same problem. In addition, text often lags the keystroke significantly. I have performed disk repair.
Below are the feedback messages that I have sent about Lion.
7-30-11 On five occasions the system has frozen on startup. Half the time it takes an excessive amount of time for the computer to complete the startup process. Programs lag periodically when commands enter and the autosave feature slows the processes significantly. These are the kinds of issues I expect from Microsoft, not Apple. I have never had these kinds of issues with an Apple OS before. I am very disappointed.
7-31-11
Well, this is getting to be a bad habit. At startup the screen freezes, the cursor can be moved; however, (and this is relatively important) no programs , menus, files, can be selected. Basically it turns into a painting with a cursor. About 40% of the time it takes two attempts for Lion to get off its haunches and get hunting. In addition, the appearance of text still significantly lags the keystroke, even in Safari. I think that Lion was misnamed. A better name would have been Siamese or maybe gigantic fur ball. But, what's in a name? A turd by any other name would just stink as badly.

Start up screen freeze. keep buffering how i can get rid off . I have iMac desk top OS X

I have iMac desk top OS X. tried to install mountain lion. after download the screen freeze on me, keep buffering and doing nothing. I turned it off on couple of times
it goes straight back to buffering

Where exactly did you download Mountain Lion from? To the best of my knowledge since Mavericks was released, Apple only make ML available on DVD at:
http://store.apple.com/us/product/D6377Z/A/os-x-mountain-lion

Screen freezing randomly.

Tried verify and repair disk, or permission. Reinstalled mountain lion and using migrate from my time machine backup. Nothing happen, still screen freeze randomly and the mac just crashes.
Spec of my mac:
-early 2011 macbook pro 15"
-2.2 Ghz I7
-AMD 6750 1gb
-OS X 10.8.3 (12D78)

Hope someone can tell me what happen, have no trouble using and playing games on the bootcamp which is operated by Win 7 64bit.

Ouch - thank you very much for the update.
I've got the same model MacBook Pro8,2 (early 2011) and an AMD Radeon HD 6750.

My iMac screen freezes and a grey colour slowly creeps down my screen

Hi, my iMac screen freezes and a grey colour slowly creeps down the screen and has a large black square in the centre saying "You must restart your computer by pressing the power button and then pressing it again to restart" or words to that effect in English and about 4 or 5 other languages. I find this happens more frequently when I try to stream movies or tv shows. It also happened when I was trying to download a couple of tv shows from iTunes.
It also sometimes makes a wierd sound a kind of loud noise like a record stuck in a groove. This has happend many times since upgrading to Lion. I hear a lot of people on here talking about their screens going completely black and not responding. I believe that mine has only gone black a couple of times and I couldn't wake it up from "sleep mode" with the mouse or keyboard. I don't know if this is also happening to other people, but my bluetooth keyboard keeps disconnecting all the time since the upgrade as well, it's driving me nuts!! Plus my wifi will show that it is fully operational, however, I can't use the internet when I wake my computer from sleep mode. I have to click on wifi and turn wifi off then on again before i can use it.
Is Apple going to come out with a fix or are we going to eternally suffer indefinitley.

Hi Eric,
I don't know why it didn't work before, but here is the most recent errol log. It crashed again about an hour later. If there is a solution, i would greatly appreciate knowing what it is because I can't enjoy using my computer anymore because of these constant crasahes.
Thanks for your time.

Osx screen freeze

Hi all, I have a macbook pro early 2011 and a few days ago I installed Lion Mountain, the first day everything is fine, but a couple of days every now and then the screen freezes (or becomes blue or black or busts the image) therefore I am forced to restart.
Initially I thought it was a mistake of VL, but recently it has started to do it without using it. Does anyone know how to fix?

If the machine is freezing then I'd keep Activity Monitor (Applications - Utilities - Activity Monitor) continually running and then when it freezes look look for processes that are either using huge amounts of RAM and/or are large %CPU. That will tell you if you have a RAM issue or a problem process that needs attention. With the small amount of information we have thats about all I can suggest. YouTube videos are HUGE RAM hogs because they on Flash so even though you have 12 GB you may need to figue out how to manage your RAM differently. Keep an eye on AM for now though.

Alarm sound and screen freeze

I have a 13 inch MacBook pro running OSx lion, after around 2 hours intermittent alarm sounds and screen freezes with coloured checks, reboots ok but reoccurs, it has a ssd drive any suggestions?

I just had this happen. I just installed new memory. Did you install any new hardware.

Gray screen after screen freeze and finder+all programs restart.

Sometimes, (like 4 or 5 times a day) my screen freezer, i get a loading circle, a gray screen and then Finder and all my programs restart.
It's doing that since i updated to Osx lion.

- 15" MacBook Pro 2006
Does anyone know what this is? And how do I solve this problem?
Because its shuts down everything im busy with (and doesn't save it).

I found this to work at least to get in and backup some files. It is VERY important to put these commands in EXACTLY as seen here, including spaces.
Boot into Single-User mode (Command-S while booting up)
Execute the following commands:
/sbin/fsck -fy /
/sbin/mount -uw /
mkdir /Disabled_System_Library_Extensions
cd /Disabled_System_Library_Extensions
mv /System/Library/Extensions/ATI* .
mv /System/Library/Extensions/AMD* .
touch /System/Library/Extensions
exit
I guess these two graphics extensions go bad quite often on Macbook Pro 15-inch. They are part of the logic board. The only problem I had was I still couldn't get into my computer any other way, and the graphics for Safari were messed up. Firefox was okay. Good Luck!

Random screen Freeze, but mouse is responsive

Hi,
For the last month, I have been having random screen freezes , requiring me to hard-boot the computer. During this freeze the mouse is responsive. I wait 15 minutes to see if the freeze goes away before rebooting.
I have re-formatted the disk and installed Mountain Lion, again , but it did not help. Most of the time it seemed to happen when I am using Safari, but this is not always the case.
The hardware tests came clean.
I have isolated the console logs to the following just before the issue happens. Any suggestions on how to proceed?

Back up all data immediately as your boot drive may be failing.
If you have more than one user account, these instructions must be carried out as an administrator. I've tested them only with the Safari web browser. If you use another browser, they may not work as described.
Triple-click anywhere in the line below on this page to select it:
syslog -k Sender kernel -k Message CReq 'Channel t|GPU D|I/O|n Cause: -' | tail | open -ef
Copy the selected text to the Clipboard (command-C).
Launch the Terminal application in any of the following ways:
☞ Enter the first few letters of its name into a Spotlight search. Select it in the results (it should be at the top.)
☞ In the Finder, select Go ▹ Utilities from the menu bar, or press the key combination shift-command-U. The application is in the folder that opens.
☞ Open LaunchPad. Click Utilities, then Terminal in the icon grid.
Paste into the Terminal window (command-V).
The command may take a noticeable amount of time to run. Wait for a new line ending in a dollar sign (“$”) to appear.
A TextEdit window will open with the output of the command. Normally the command will produce no output, and the window will be empty. If the TextEdit window (not the Terminal window) has anything in it, post it — the text, please, not a screenshot. The title of the TextEdit window doesn't matter, and you don't need to post that.

Firefox can't open normally without going through the "this is embarrassing" routine; nor does it close down properly; it also sticks frequently, i.e. screen freezes for a minute or more; should I uninstall and re-install to try and debug?

Firefox can't open normally without going through the "this is embarrassing" routine; nor does it close down properly; I get the "end program" message and have to say "end now"it also sticks frequently, i.e. screen freezes for a minute or more; should I uninstall and re-install to try and debug?
- I've used Firefox exclusively for around 2 years.
- My outlook express has no problems
- other programs seem unaffected; it seems peculiar to Firefox.
- my main use is surfing the net, primarily entering competitions on line via specialist competition sites.
- every day at some stage(s) I have to switch computer off as Firefox has got very slow/sticky/freezes.
I'm not techy by any means, but I can only thing of un- and re-installing to hopefully start with a clean slate.

Sounds like something is keeping Firefox from closing properly. See this: <br />

When I go to a website, it half-way downloads and then the screen freezes for 10-20 seconds while ads appear; this never happened till recently.

Until recently, I loved Firefox. Lately, when I go to any website and try to download a page, the screen freezes for between 10-20 seconds while ads load. Why the screen freezes is both frustrating and annoying. I have the latest version, nothing on my computer is different, and as I said, it didn't used to do this. Any ideas what's going on?

Create a new profile as a test to check if your current profile is causing the problems.
See "Basic Troubleshooting: Make a new profile":
* https://support.mozilla.com/kb/Basic+Troubleshooting#w_8-make-a-new-profile
There may be extensions and plugins installed by default in a new profile, so check that in "Tools > Add-ons > Extensions & Plugins" in case there are still problems.
If that new profile works then you can transfer some files from the old profile to that new profile, but be careful not to copy corrupted files.
