MacBook freezes after memory installation

I have a 2006 13-inch MacBook. I recently upgraded its operating system to OS X 10.5.8 and yesterday I installed 2 new memory modules of 1GB each to reach the maximum 2GB memory. Last night and today upon trying to start the computer by pushing the power button I got a repeat sound like the computer was trying to start (like an engine turning over) but it didn't start up until something I did finally turned it on (I'm not sure what). Today the problem repeated itself. I finally got it to turn on by pushing the power, option, command, and P and R keys simultaneously (a suggestion in the user's guide) and that seemed to work, but I'm afraid this is going to happen every time I try to turn the computer on. The battery is fully charged, too. Any ideas? Thanks!

I'd suspect those RAM cards, make sure they are fully pushed home, they can need considerable force depending on the manufacturer. If that doesn't work you may have to get some alternatives, BTW what RAM manufacturer did you use?

Help my MacBook freezes after I log in.

If you hold down the "shift" key on your keyboard when you log in, does the same thing happen?

MacBook freezes after shutting the screen closed down

Since some time ago, my MacBook freezes when I close the screen down for substantial time like a few hours or maybe even an hour, so that I have to kill the MB by pressing the power button for a few seconds. I did this almost everyday for maybe a few weeks now. Perhaps this is the after effects of a fall and there is no cheap cure for it?

Many here have reported no wake from sleep or failure to sleep, running 10.6.3 and other versions, on MacBooks and MBPro's, using Parallels and VMware. Some say deactivating the Sudden Motion Sensor and shutting down Parallels and VMware ,before sleeping, helped.

Macbook freezing after waking from sleep

My 4 GB RAM macbook freezes for 30 seconds after I wake it from sleep mode. Sometimes it is unresponsive and sometimes the beachball comes up. I have 200 gigs of free space and no login items. The bluetooth wake is also turned off. What is the problem?

I have noticed similar behaviour. I think it depends on the network activity being carried out when I closed the lid, and maybe it has to wait for something to time out. I don't really know, I'm just guessing.
I have noticed that when it happens, I have to close the lid and watch the light on the front. This will be solidly lit. When it starts "breathing" I can open my MacBook again and it will work ok.

Help: Macbook freezes after sleep and gray screen freeze on startup

I've got a new MacBook (45 days old, minimal usage) and I'm starting to have some problems.
When my computer goes to sleep after inactivity I have a hard time waking it. The screen turns on right away but the mouse/cursor remains frozen. The computer does not respond to any keyboard commands. I usually have to reboot the machine when this happens. I noticed this problem a few weeks ago and it has since become more and more frequent.
I've also noticed that with some regularity my computer freezes on the gray screen during start up and never reaches the mac icon. This has become more and more frequent since I first noticed the initial problem and happens one in every 3 or 4 startups.
I haven't installed any new software except for the regular software upgrades. Nothing extraordinary.
Is it possible that these problems are related? Am I doing something wrong?
Any help would be greatly appreciated.

The grey screen on startup may be the known issue, especially if you start to get vertical lines on the screen. If you can reboot using PRAM reset, go to the displays control panel, set the resolution to something besides your current resolution, then revert to your original setting. That should fix that part.
As far as the freezing after sleep goes, I had a similar issue where the macbook would not actually go to sleep (white light stayed solid), and opening the lid would result in a dimmed screen that I had to force-shut down the computer to get out of. After sending it in for RSD, this seems to have been resolved.

Quirky Macbook Pro After Memory upgrade and big movie project

Hi all,
Last December I made a movie for a class project with imovie. I noticed that the processor temp got up to 180-190 degrees for long periods of time (I use Intel's CoreDuo Temp reader to tell). Ever since then my MBP has been real flaky and weird. I wonder if I burnt the chip or something. Here are some of the issues
Applications crashing (Apple and 3rd party)
hard time finishing big tasks (i.e. they start but then crash towards the end)
major slow downs at odd times
Overall loss of performance
Beachball for no reason
WILL NOT ARCHIVE!!!
WILL NOT TRANSFER BIG FILES TO EXTERNAL HD!!!
(those two are big to me)
I found a great app called fancontrol 1.1 and since then my temps have been down. wish I knew about it before my project. It's as if I can't trust this thing with anything more than surfing the net. Even that has been messed up lately.
I recently bought an extra gig of memory (I used 667 mhz ddr2 sdram bumping it to 2gb total) and that made things worse. Apps and performance are a little more unstable. I then completely wiped the hard drive and reinstalled the OS and all the updates and it still runs noticably slower than when I first got it. Stability got better but not at the level I would expect with 2gb of ram. I barely made it through making a movie yesterday. Had a crash at end of burning the DVD and had to re-render everything.
My biggest fear is that since I have one of the first Macbook Pros (I was one of the waitlist people) that I am screwed out of my warranty. I think it expires sometime this month. I use this thing everyday and I can't afford to upgrade. I'm pretty savy with macs and I've done about everything I can. Any advice or insight will be much apreciated.
MacBook Pro 1.83 ghz 2gb Mac OS X (10.4.8)

Among other things: Have you performed the firmware updates required for your particular model?
Have you run diagnostics? Boot from the OS X Installer Disc One and after the chime press and hold down the "D" key until the diagnostic screen appears. Run the extended tests several times.
Check that you have properly installed the added RAM. It's quite easy to insert it improperly. Remove the new RAM module to see if the problems cease. If they do you have a defective module.
Under heavy load it's not uncommon for the CPU core temperature to reach 83-85 ºC. Normal idle temperature may range between 40-45 ºC.
Otherwise, take the computer to an Apple service center for service.

Macbook Freezes after 4 GB RAM upgrade

I work on many Macs for my company, and we have been upgrading our Macbooks with 4 GB of RAM standard. But this causes the screen to freeze, image to break up into different colors and locks up the whole system.
I thought it was the OCZ RAM we were using, so we switched to Crucial. But the same problem exists, and it exists on over 10 machines so it cannot be that all of this RAM is failing. This must be a problem with the unibodies or with OS X?

Please note, I am fairly new to Mac, and only found this info after much searching on-line...
I also have had problems after upgrading to 4GB of RAM, I bought Kingston from Best Buy in Edmonton, AB. I have spent a great deal of time searching for a solution, and just thought I would share what I have found.
It seems to be an issue with the NVIDIA GeForce 9400M graphics card and the way it accesses memory, and it seems to affect anything over 3GB of RAM. Now that being said, on Nvidia's website, with some searching there is a pdf document stating which RAM is compatible with this video card. I should mention that this issue also affects MacBook Pro users with the 9400/9600 graphics card. According to the pdf, my Kingston memory is not on the compatible list...I'll try to include this list:
The tables below list the SO-DIMMs that NVIDIA plans to support on their GeForce 9400M G platform.
Note: Using an SO-DIMM from this list does not imply reduced or simpler design validation on the part of the OEM. NVIDIA recommends customers to perform their full suite of memory interface design validation testing on their systems.

The first part is the manufactrer name, next is type of memory, then latency, then density, then part number.
Another solution seems to be to edit the com.Apple.Boot.plist to set maxmem to 3456, which cuts available memory after rebooting to 3.5GB, on my MacBook, I got fair results with 3072, basically 3GB, it doesn't freeze as often, although I haven't played any movies, etc, for a few days, which always seemed to lead to my freezes. But the system seems much more stable for the moment.
Another solution which I am going to test when I get home and have access to my original RAM is to put one of the 1GB sodimms which came with my machine in the first slot, and one of my Kingston modules into the other slot, I've read that this solves the problem completely. Now I realize this leaves you with 3GB Ram, not the 4 I wanted, but further research showed me that the performance hit is not that significant from 3 to 4 GB, There are a couple of websites with testing results for different RAM configurations, and for my needs, the difference is minimal, I know that may not be acceptable to everyone. If I had bookmarked one of these pages, I would include the link.
Another solution seems to be a change to one of the Kext file, link is here: http://www.insanelymac.com/forum/index.php?showtopic=127611
but this is related to kext for MacOSX on a PC, and I don't know enough about dealing with kext files to feel comfortable doing things like this to my MB.
I don't know if anyone else will find this useful, but if it does, great. In the meantime, I will be able to test the 3GB RAM configuration on Friday, and will test out the MB with movies, etc and post how it goes... one test I read about is to use the program REMBER, and do multiple hard drive searches, etc while it is running, according to the website I found that on, it leads to the freezing fairly rapidly, so at least the problem can be reproducible for those who take their Mac Books or Mac Book Pros into an Apple Genius Bar or where ever so that they can see the freeze in action.
Cheers,
Dan

Freezing after HD installation - failure - HELP.

Hi,
Major major problems after attempting a HD upgrade. Initially the system was freezing when a Seagate Barracuda 400GB drive was installed as primary boot drive with 10.4. installed. Jumpers were set to master - with drives 2, 3, 4 running off a SATA controller. After 2/3 minutes - system would freeze and required force quit. So removed drive - re-installed 80GB drive and the same is happening. Help.
The boot drive has Tiger - my question is - could the failed installation upset the CPU - and if so - should I re-set it? I've even tried re-booting of a secondary drive running 10.3.9 - and the same thing happens - total freeze.
All suggestions for cure would be appreciated.
BB

Hi Majordadausma,
Haven't tried changing the jumper to cable select yet - thanks for the advice. I've actually ordered a Dual core G5 - because IMO - the G4 just can't handle my power apps + Tiger. Re-setting the pmu stabilised the system to work with - and when i have the new G5 - i'll get back inside the G4 and try your tip. Too scared to attempt any more meddling just now.
Finally - I did note the Seagate Barracuda 7200.8 - ST3400832A firmware was 3.03! Could this be significant as the other HD in the G4 has firmware 3.06?
Regards,
BB

After installing ox lion macbook freezes after start up

so... just like the title says. after installing ox lion on my macbook pro, sometimes it freezes right after start up, and I could not click on anything, and i had to force it to shut down by holding the power button.
I don't know if anybody else have the same problem or not? is it a bug or something? hope it can be solved soon.....

I just don't know if this is showing some sort of problem..
If your Mac boots to the Desktop without freezing, nothing to worry about. The screen color may vary somewhat betweeen one Mac OS X to another.
This can help startup issues also.
Disable the Lion "resume" feature ...
Open System Preferences > General

Macbook freeze after Lion

My Macbook Pro freezes every now and again, especially when using Safari. This happens after an upgrade to Lion.
When I pop out the forced stopping window and give it the command to stop Safari, that window to freezes.
Mouse pointer still moved though, but can't select anything outside the frozen window's scope.
Safari was not running full-screen this time, so the link I suggestede earlier is not confirmed.
Hope This Helps in solving the issue.

I am having the same problem except I get the pinwheel and cant do anything, it just freezes randomly. However mine freezes upon reboots if i do not leave that box checked that says to reopen windows. I have to hold the power button down to shut it down then it will come back up ok. I hope they fix this with a patch soon especially since I had 0 problems before the upgrade

MacBook freeze after desktop loads

I repaired permissions, and this still occurs. I have a new insall of OS 10.7 as I purcahsed a new HD for my MacBook.
Any ideas what would cause this?
Any ideas how to reover or force a reboot when it hangs? Right now I am just holding the power button until the MacBook powers off.

You're responding to a post from five months ago. If that's how long you had to wait for the issue to reappear, it may never be resolved.
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.
☞ If you’re running Mac OS X 10.7 or later, 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 freeze, 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 or hang logs — they're very long and not helpful.

MacBook freeze after upgrading the hdd

Hello,
I have following problem with my MacBook. I have made a upgrade of my harddisk to a 500gb WD Blue Skorpio Harddisk. I made a backup of the old HDD and install the new HDD. After the changing, the computer boot normal. But then he freezes every time for a few seconds.
For Information: The HDD is partition into 2 GUID Tablet Parts. What is your recommandation. It is a problem of the HDD or it is a Problem of my MacBook.
I asked Western Digital for support, but I get no answer. I hope some knows the problem and can help me.
Perry_R

Hello Jay
Hello iyacyas
thank you for the fast response due my Problems. In the evening I will try Jays recommendation.
@iyacyas
The only reason to use two GUID Partitions is, to have a better overview about my files. In the main Partition I have all Mac OS files. The second Partition is for Medial file, like Music, Videos and Pictures. There is the folder of iTunes. I know, I didn´t need such differentiation. But to hold that were a good idea to get a better overview about my files. Sorry I worked too long with windows.

My Macbook freezes after using it for awhile

I startup my MacBook (aluminum 2008 verions) running lion 10.7.1 and after about 5 minutes of using it, my computer displays the rainbow cursor and freezes. I am unable to click on anything or force quit.
My processor is 2.4 Ghz and has 2Gb ram.
It would be great if someone could give me any thoughts ASAP as I have an assignment due next week and need my computer.
Thanks in advance

Your problem is caused by third-party software that you installed. I'd need more information to be more specific.
Reboot as usual (not in safe mode) if you haven't already done so. Launch the Terminal application, copy or drag -- do not type -- the line of text below into the window, and press return:
kextstat -kl | awk ' !/apple/ { print $6 $7 } '
Post the lines of output (if any) that appear below what you just entered (the text, please, not a screenshot.)
Next, do the same thing with this line:
sudo launchctl list | sed 1d | awk ' !/0x|apple|com\.vix|edu\.|org\./ { print $3 } '
That's one line, not two. You'll be prompted for your login password, which won't be displayed when you type it. You may get a one-time warning not to screw up. You don't need to post the warning.
Next, this command:
launchctl list | sed 1d | awk ' !/0x|apple|edu\.|org\./ { print $3 } '
Again, one line. Finally, one more:
ls -1 /Library/{InputManagers,StartupItems}
Remember, this is all drag-and-drop or copy-and-paste, whichever you prefer -- no typing, except your password.
You can then quit Terminal.

Macbook freezes after change of wifi location

Finally I can reproduce the freezing of my macbook air. If I change from wifi location for example i go to work from home the following happens:
the MBA will not fall a sleep resulting in a very hot MBA in my bag.
the MBA will fall a sleep but it is not possible to wake it up again
the MBA will fall a sleep and is able to wake up again after opening the lid but now it will freeze the entire mac within 5-10 minutes.
I have to push the power button for a long time in either cases.
I just did a complete restore so i have no extra software installed.
Is repair the only option here?

Can you reproduce the problem after erasing the startup volume and installing OS X, without restoring anything from a backup? If so, the machine needs to be serviced.

Constant freezing after clean installs of OS X

I have a Late 2008 Macbook Pro.
I did a clean install of the OS and immediatly after booting into OSX, the system freezes and I get the spinning beach ball. Sometimes it lets me click on Finder, but then it just freezes again.
I have installed Leopard, Snow Leopard, Lion and Mountain Lion, each time formatting the hard drive and doing a clean install. It happens everytime on each version!!!
I have checked disk permissions and verify disk through Disk Utility. Comes back clean.
I have ran the apple hardware test. Comes back clean.
Here is the kicker. It works perfectly in SAFE mode. It does not freeze up at all.
Please help! I've spent many hours (20+) trying to fix this.

Are there any methods to confirm a faulty graphics adapter, such as running some kind of diagnostics? Im assuming the graphics card is built into the logic board so I cant just replace it. In Windows I could reinstall the graphics controller and reinstall the driver. Are there any Mac equivilents to this? I am fairly new to Mac troubleshooting.
