IBook freezes every hour

while on a public WiFi network. Any public WiFi network - actually I don't have access to private ones. It looks like the laptop momentarily looses connection, then Safari stops responding, then Finder stops responding and then the only solution is reboot. This pattern started sometime at the beginning of the summer. Any ideas?
Eugene

In the meantime, a possible workaround to rebooting is to use one of these lines in terminal...
sudo ipconfig set en1 BOOTP;sudo ipconfig set en1 DHCP
sudo ifconfig en1 down;sudo ifconfig en1 up

MacBook Pro 15" Late 2013 freeze every hour at the same time

Hi guys,
My MacBook Pro 15" Late 2013 Retina freeze every hour at the very same time. Before every freeze in console i see something like this:

I have 512GB SSD Drive which has 2 partitions. One for Mac OS X 10.9.4 (13E28) one for Windows 8 (which I'm not using) also I have Parallel Desktop App which I use once a month. Also I'm using TimeMachine + external HDD (do backups once in 2 weeks).
Everything was ok for 4 month. A month ago I've start experiencing freezes 1-2 a day and now it became worse, every hour. I've try to repair disk permissions, repair disk. Does anyone know how to fix this issue?
I read in one of the website that some people fixed this issue updating ssd firmware. But I'm not sure where to get firmware for my ssd.

Sorry I missed that.
This is what I think is happening:

There are two options, keep the Time Machine HDD connected full time or turn Time Machine off and on only when you want to make the backup.

Computer freezes every hour

I built my brothers computer about 2 years ago and there were no issues. Awhile ago he uninstalled itunes from the C drive and installed it on the F drive. Well when he did this is when the computer started freezing every hour. Whether that was the exact
cause or not, I'm not sure. I tried reinstalling it back on the C drive but it still freezes. I retrieved the admin logs for when the error occurred. There were 5 events. I have them zipped up but I don't know where I can upload them on here. Any help would
be most appreciated, I've spent hours looking for a solution.

Hi, sorry for the delay. It's been a busy couple of days. I was toying with my brother's computer yesterday and this is what I came across. The computer has a Crucial M4 64GB SSD (C: drive) which is used for the OS basically. He also has an external HD (we
will call it F drive). Whenever I unplug the external and manually restart the computer, it restarts as normal. However, when it freezes and I restart the computer by actually shutting down the comp, it doesn't recognize the C drive. It boots to the bios but
I don't have the ability to change the boot order because it doesn't recognize the C drive (the F drive is unplugged). Once I plug the F drive back in and restart the computer, it will boot up as normal. The F drive is purely for programs, everything OS related
is on the C drive.
I also tried to install something from windows update but it got stuck, blue screened (I wasn't able to see what it said) and eventually froze on checking for updates. I'm suspecting it may be a hard drive failure but I'm not 100% certain.
I've never used skydrive so I hope I did it correctly. I just uploaded the zip file. Thank you for all your help.

Macbook freezing every hour

I've had my laptop for about a year and a half now and recently its just started freezing every hour and the spinning wheel appears but i can still move the cursor, this lasts for a couple of minutes and then everything starts working fine again. I havnt dropped it or done anything different from how i usually treat it and havnt downloaded any new software recently. Anyone know what might be the problem or how I could fix it? Its pretty annoying when im trying to work.
Thanks

Open your Activity Monitor.app.
Leave it open so that you can see the contents of the window.
Now click the banner for the CPU% so that it is sorted showing the highest usage at the top of the list.
Next step, play the waiting game =) you need to make sure that you can see the list in the Activity Monitor when the time comes around that everything is freezing.
Look at the list, when it freezes up and see what is at the top of the list for CPU usage. Also note what the CPU usage is listed at. (write down the top 5 items and the cpu usage)

Snow leopard freezing every hour at the same time

Hi all,
I've been having freezing problems with my macbook pro. I'm running 10.6.4 and have noticed that every hour to the exact minute, my computer will be unresponsive for approximately 30 seconds to a minute, and then returns back to normal.
The time that it freezes will vary from day to day, ie some days it will freeze at 7 minutes past the hour all day, other days it will freeze at 19 minutes past the hour every hour.
This has only been happening for possibly the last month, and I have no idea what is the cause. I've used console to see if get any error messages, but nothing is coming up. I'm not using time machine. I've tried restoring disk permissions.
I'm not sure whether this is a macbook pro related thing or a snow leopard related problem so excuse me for posting this in both forums.
Please help!

You're likely to need it, sooner or later. If you suspect hardware problems, for example, the +Apple Hardware Test+ on it is tailored to your Mac's hardware. If you can't find it, AppleCare will send you a replacement for a nominal charge.
If the file system on your HD is ok, and the hang occurs at exactly 60-minute intervals, then it must be related to some periodic process running on your Mac.
I'd have expected another message in your logs. There may be something that doesn't show in Console's +All Messages+ selection.
In the Console sidebar, select your system.log file; it's the first one shown in the Files folder. The I/O message should be there; confirm that they occur every hour, and see what other messages are near it in time. Again, if theres's anything dire-sounding, copy and post here.
Also open the various folders, looking for one or more named HangReporter. If you find any, look inside. Each process that generated a log there will be named in the sidebar, along with the date & time. That may provide a clue (please don't copy a whole log here; just the beginning page or so).

Transferring Images to SD Card - iBook Freezes

I'm trying to move photos from iPhoto 5 to a Kodak 512MB SD Card via a USB card reader. Trying to move about 320 images (approx 480MB). The iBook freezes every time I try to copy the files across.
iBook is a G4 with 1GB RAM. I've tried to load them a few (approx 50) at a time, but I still end up with the iBook freezing.
I'm doing this to load the SD card for a digi photo frame for Xmas pressie. Any thoughts/ suggestions?
Thanks for any help you can give me.

Thanks - I tried that (of sorts). I dragged them into a folder from iPhoto and then tried to transfer them onto the card - didn't work unfortunately.
I did solve the issue. Much to my chagrin I burned the photos to CD then dragged and dropped them onto the SD card on my mother-in-laws windoze machine (to much gloating from her!).

Why is the purge command running every hour, and freezing my system?

I noticed over the past several days that my mac pro will freeze for several seconds (clock stops, mouse/keyboard don't work. completely frozen) every hour, to the minute.
I've tracked it down to the "purge" command, which is causing the problem. But, I can't find where it's being called. Any hints where I might look to find the cause?
I don't believe this was happening a few days ago. I have installed all software updates.
I'm running 10.7.5 on a 2x2.66Ghz 6-core mac pro.
Thanks!

Please read this whole message before doing anything.
This procedure is a diagnostic test. It won’t solve your problem. Don’t be disappointed when you find that nothing has changed after you complete it.
Third-party system modifications are a common cause of usability problems. By a “system modification,” I mean software that affects the operation of other software — potentially for the worse. The following procedure will help identify which such modifications you've installed. Don’t be alarmed by the complexity of these instructions — they’re easy to carry out and won’t change anything on your Mac.
These steps are to be taken while booted in “normal” mode, not in safe mode. If you’re now running in safe mode, reboot as usual before continuing.
Below are instructions to enter some UNIX shell commands. The commands are harmless, but they must be entered exactly as given in order to work. If you have doubts about the safety of the procedure suggested here, search this site for other discussions in which it’s been followed without any report of ill effects.
Some of the commands will line-wrap or scroll in your browser, but each one is really just a single line, all of which must be selected. You can accomplish this easily by triple-clicking anywhere in the line. The whole line will highlight, and you can then copy it. The headings “Step 1” and so on are not part of the commands.
Note: If you have more than one user account, Step 2 must be taken as an administrator. Ordinarily that would be the user created automatically when you booted the system for the first time. The other steps should be taken as the user who has the problem, if different. Most personal Macs have only one user, and in that case this paragraph doesn’t apply.
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.
When you launch Terminal, a text window will open with a line already in it, ending either in a dollar sign (“$”) or a percent sign (“%”). If you get the percent sign, enter “sh” and press return. You should then get a new line ending in a dollar sign.
Step 1
Triple-click the line of text below to select it:
kextstat -kl | awk '!/com\.apple/{printf "%s %s\n", $6, $7}'
Copy the selected text to the Clipboard by pressing the key combination command-C. Then click anywhere in the Terminal window and paste (command-V). Post the lines of output (if any) that appear below what you just entered. You can do that by copying and pasting as well. Omit the final line ending in “$”. No typing is involved in this step.
Step 2
Repeat with this line:
sudo launchctl list | sed 1d | awk '!/0x|com\.(apple|openssh|vix)|edu\.mit|org\.(amavis|apache|cups|isc|ntp|postfix|x)/{print $3}'
This time you'll be prompted for your login password, which you do have to type. It won't be displayed when you type it. Type it carefully and then press return. You may get a one-time warning to be careful. Heed that warning, but don't post it. If you see a message that your username "is not in the sudoers file," then you're not logged in as an administrator.
Note: If you don’t have a login password, you’ll need to set one before taking this step. If that’s not possible, skip to the next step.
Step 3
launchctl list | sed 1d | awk '!/0x|com\.apple|edu\.mit|org\.(x|openbsd)/{print $3}'
Step 4
ls -1A /e*/mach* {,/}L*/{Ad,Compon,Ex,Fram,In,Keyb,La,Mail/Bu,P*P,Priv,Qu,Scripti,Servi,Spo,Sta}* L*/Fonts 2> /dev/null
Important: If you formerly synchronized with a MobileMe account, your me.com email address may appear in the output of the above command. If so, anonymize it before posting.
Step 5
osascript -e 'tell application "System Events" to get name of every login item' 2> /dev/null
Remember, steps 1-5 are all copy-and-paste — no typing, except your password. Also remember to post the output.
You can then quit Terminal.

Macbook Freezes every one hour. On the console I could see only LKDCHelper Starting when the OS X 10.8.3 Freezes

Hi
Macbook Pro (OS X 10.8.3) keeps freezing everyone hour. On the console I could see only "LKDCHelper Starting" message whenever MBP freezes. I dont see any other message. So, far, I have tried doing all the below.
1. Did a hardware test.
2. Started in safeboot.
3. Booted in the recovery mode and verified disk and verified permission
4. Reinstalled the OS X
Not sure whatelse I could do, could you please help?

Please read this whole message before doing anything.
This procedure is a test, not a solution. Don’t be disappointed when you find that nothing has changed after you complete it.
Step 1
The purpose of this step is to determine whether the problem is localized to your user account.
Enable guest logins,* log out of your account, and log in as Guest. For instructions, launch the System Preferences application, select Help from the menu bar, and enter “Set up guest users” (without the quotes) in the search box. Don't use the Safari-only “Guest User” login created by “Find My Mac.”
While logged in as Guest, you won’t have access to any of your personal files or settings. Applications will behave as if you were running them for the first time. Don’t be alarmed by this; it’s normal. If you need any passwords or other personal data in order to complete the test, memorize, print, or write them down before you begin.
Test while logged in as Guest. Same problem?
After testing, log out of the guest account and, in your own account, disable it if you wish. Any files you created in the guest account will be deleted automatically when you log out of it.
*Note: If you’ve activated “Find My Mac” or FileVault, then you can’t enable the Guest account. The “Guest User” login created by “Find My Mac” is not the same. Create a new account in which to test, and delete it, including its home folder, after testing.
Step 2
The purpose of this step is to determine whether the problem is caused by third-party system modifications that load automatically at startup or login, or by a peripheral device.
Disconnect all wired peripherals except those needed for the test, and remove all aftermarket expansion cards. Boot in safe mode* and log in to the account with the problem. The instructions provided by Apple are as follows:
Shut down your computer, wait 30 seconds, and then hold down the shift key while pressing the power button.
When you see the gray Apple logo, release the shift key.
If you are prompted to log in, type your password, and then hold down the shift key again as you click Log in.
Safe mode is much slower to boot and run than normal, and some things won’t work at all, including wireless networking on certain Macs. The next normal boot may also be somewhat slow.
The login screen appears even if you usually log in 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.
*Note: If FileVault is enabled, or if a firmware password is set, or if the boot volume is a software RAID, you can’t boot in safe mode.
Test while in safe mode. Same problem?
After testing, reboot as usual (i.e., not in safe mode) and verify that you still have the problem. Post the results of steps 1 and 2.

My firefox stops responding and fades for about a half min almost every hour, OR MORE often

My firefox stops responding and fades for about a half min almost every hour, OR MORE often.
I am typing a message or information, the screen fades to about half bright. the curser freezes in place and no key responds.
The information bar at the top of the page says "firefox not responding" in about 30 seconds it restores and continues as tho nothing happens.

I might have discovered the solution without starting over with all your places and bookmarks.
Right after i installed 7.0.1 over a week ago,every 10-30 min When i would be watching videos online, it would freeze for 20-30 seconds. Firefox would say ( Not responding) both firefox and the plugin container process would be very large memory files. I tried to go back to Firefox 5.0. No avail it would still freeze.I tried to disable the plugin container . no good. I tried to adjust memory or cache or plugin settings in “about:config”.Nothing fixed it!
I finally discovered why my Firefox 7.01 was periodic hanging fix. It is something to do with some of your personal files. download this this add on and install it
https://addons.mozilla.org/en-US/firefox/addon/places-maintenance/
or you can Google "places maintenance Firefox"
After you install the add on, restart Firefox.go to "tools", then "add ons" and then click “extensions” tab ,then click' options" on the "places maintenance" entry. choose "ALL' or just "expire" and hit "execute", then wait until its done., restart Firefox. should be fine then and all my bookmarks, customizations ,settings, and history stays untouched!
After i did this my Firefox did not freeze once for over 3 days straight. Might not work for everyone. I already read that Mozilla is aware of the problem and are working on a fix it in the full version of 8( the 8 beta did not fix the problem for me) . But they said this is a good temporary fix at least,( might be permanent)
For me at least ,Firefox works fine in 7 now. perfect actually.And many people i saw on similar forums had similar problems.
Enjoy. Hope this helped

Mac keeps freezing every 15minutes even when re-installing of OS

I tend to have this issue after I've updated my latest OS to 10.4.11... My mac has the tendency to freeze every 15-20minutes... After checking my hardware realising that it's still in good working condition, I downloaded main menu to do a clean up... It has more or less fix the problem but it comes back after I updated my Safari browser...
Unknowingly what's the underlying cause, I decided to re-install the OS... The more frustrating thing is that it hangs even when I re-installed the OS, approximately about 15 minutes before the entire set-up is done... I've no choice but to restart my mac.. But not it seems I can't really boot it as it even hangs during start up...
Really at wit's ends... Can anyone help??
Thanks

Hi S.U,
No problem at all.. But really thanks for your advice which I think it might be the case...
My mac is the very first G4 batch and it's about coming to 5 years old... My harddisk crashed 2 years back and had sent it for a replacement from a 30GB to a current 120GB HD... I do face initial software problems after the fix and I got it back again and the technician install my mac with his Tiger installation disc instead on what's my initial package comes with... It worked fine subsequently for the next 2 years till recently, especially I've not been using my mac for months, the hanging issue came... Frustrating as it is, I had thought it's due to the upgrading of the OS and security measures that's too taxing for my current hardware... But now since you mentioned about the additional hardware problem that any hardware software can't detect, I'd think it stands a pretty high chance since I had once had my harddisk replaced and my mac being too old and wear and tear could be a problem...
I had managed to do an Erase and Install the OS last night despite after several hanging sessions during the reinstallation program... I've updated my OS to the latest 10.4.11 with security added... Right now my mac appears to look fine after operating for several hours of software updating, reinstalling of all my other applications as well as moving my back-up files back to the system... I hope after all these, the hanging issue won't persists though I have this feel that it might not be fully resolve and my sister is saying that I should get a new mac with extra huge space RAM and processor to suit an extra huge consumer like me...
Well, for now I just have to KIV and I hope this current mac of mine can stay on till I get a new mac...
But anyway, thanks for your advice, will look into it seriously if the hanging issues come back again...

MacPro freeze every night

Hello
My MacPro 2.66 with 10.5.1. Freeze every time when I leave it alone about 6 to 8 hours. The screen saver freeze. When I tape the keyboard and click the mouse. No response... I have no choice but to turn it off and on by the bottom in front of the machine....
If I turn it into sleep mode. No problem. I have checked the Machine by the the hardware test. No problem. I try to reset the PRAM. No use.
Even I don't let my harddisk sleep. The problem still here.
Can anyone help? Thanks so much
Eric

Did you install 10.5.1 over your previous system? If you can backup your important files to another drive, it would be best to erase your startup drive and reinstall Leopard from scratch.
Do not do an archive and install or upgrade install; do the erase and install. Afterwards, repair permissions in disk utility and use software update to get the updates; repair permissions again.
Clean installs of Leopard seem to clear up a lot of problems for a lot of people.

Airplay disconnects every hour

I have a late 2013 MacBook Pro running OSX Mavericks 10.9.2 connected using AirPlay to an updated AppleTV. I am NOT running battery power. Using iPhoto I am playing a slideshow on the TV. The slidewhow runs seamlessly but the AirPlay connection automatically disconnects every hour (exactly one hour).
It is not a networking issue associated with any latency or interference. There are no other devices on the wireless network; the environment is free of other sources of competing RF energy. I have no overlapping channels, competing radios or other sources of RF energy in the same frequency range (I live in the country and the nearest home is more than 1/2 mile away). There are no operating microwave ovens, bluetooth devices, cordless phones, baby monitors or other potential competitors in the area. Even if such interference were present it would not account for an interruption that occurs at exact 60-minute intervals. To further prove this I have verified that the problem still exists when connected via Cat5e.
When the AirPlay connection is broken the slideshow continues to play on the MacBook. If I stop the slideshow and re-start it the mysterious 60-minute disconnect counter does NOT reset; it still disconnects exactly one hour after the AirPlay connection started. This suggest the issue is not a timer or setting in iPhoto.
I tried unchecking the "Automatic graphic switching" box in the Energy Saver section of System Preferences but this actaully caused a random freeze in the slide show.
I suspect there is a setting somewhere that I am unaware of or have overlooked. Has anyone had this problem or can you suggest a fix? There are lots of posts on the Internet of people having AirPlay disconnect at irregular intervals but I cannot find one that addresses a non-networking-related every 60-minute disconnect.
Any insight will be appreciated.

It may be worth looking at what your DHCP lease is set for on your dhcp server. If it is set for a 1 hour lease it may be the cause. You could try setting up the ATV and the Macbook Pro with a static IP or set your dhcp lease to expire at a longer interval, say 4 hours to see if it goes longer than an hour. I have seen dhcp lease setting cause this type of problem in the past.

Blackberry 8320 freezing every 3 seconds???

Hi there, I've had my 8320 for about a year and a half now, still has the original OS on it, haven't updated anything major. About 2 days ago, it started "freezing" every 2 or 3 seconds. By freezing I mean, the little hourglass will pop-up for 3 seconds then dissappear. This won't stop. Also, it is doing this so much, that it drains the battery in a matter of hours. Any thoughts on what could be happening? Thanks!

Low memory likely, for one thing:
First thing? Check the File Free at Options > Status, what is the number at File Free?
Now, leaving the device powered ON, remove the battery of your device, hold a minute, replace and reboot. What is the File Free now?

OSX now crashes every hour. OSX apps like Dock, desktops, launchpad, finder, toolbar, etc become unresponsive, although sometimes non OSX apps (like Chrome, TextMate, etc) remain functioning briefly. No obvious reason or trigger

OSX now crashes every hour. For no obvious reason or trigger, suddenly OSX apps like Dock, desktops, launchpad, finder, toolbar, etc become unresponsive, although sometimes non OSX apps (like Chrome, TextMate, etc) remain functioning briefly, before the whole thing hangs and needs a hard reboot.
It is not apparent what I do to provoke the crash -- it happens while I am in seemingly any application, sometimes just reading a page and not taking any actions.
This started happening very suddenly two days ago. It might have happened around the time I updated ITunes but I'm not sure of this at all. And I never use ITunes or have it open.
Don't know how to diagnose the problem since nothing is accessible whence it freezes up on me. I tried software update, but problem continued after. Would appreciate troubleshooting advice. Thanks!

☞ 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 icon grid.
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. If you don't see that menu, select
View ▹ Show Log List
from the menu bar.
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 after you had the problem. Select the messages logged before the boot, while the system was unresponsive or was failing to shut down. Copy them to the Clipboard (command-C). Paste into a reply to this message (command-V). Please include the BOOT_TIME message at the end of the log extract.
If there are runs of repeated messages, post only one example of each. Don’t post many repetitions of the same message.
When posting a log extract, be selective. In most cases, a few dozen lines are more than enough.
Please do not indiscriminately dump thousands of lines from the log into this discussion.
Important: Some private information, such as your name, may appear in the log. Anonymize before posting.
Step 2
Still in Console, look under System Diagnostic Reports for crash or panic logs, and post the entire contents of 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.
