Thought I had it fixed, by iMac is still freezing sometimes on boot up
In an earlier post, I thought we had my iMac fixed but now it's still freezing up on boot up, occasionally.
Sometimes I'll just get a grey screen with no logo after the boot up chime, sometimes it'll take a good minute or two for my iMac to fully boot up, and sometimes it'll boot just fine.
Usually, when I get just the grey screen I have to use the Command-Control-Power button to reset the Mac just to boot.
Any ideas as to why? I've repaired the hard disk after the first time this happened and it found no errors.
I read my console log and there's nothing glaring out that looks like a massive error.
I have been getting the following errors, could they be the problem?
BootCacheControl: could not stop cache/fetch history: Cannot allocate memory
vmnet: Hub 1 does not exist, allocating memory.
Any help would be greatly appreciated.
As a follow up to this.
I booted from CD and ran disk utility. I repaired the disk and said everything was A-ok. I tried to repair disk permissions and it the progress bar froze a 1/3rd of the way in saying "1 minute remaining" and never moved after that.
ideas?

Printer not responding after upgrade -- thought I had this fixed
Sorry to bring this up again, but I thought I had this solved. Maybe I omitted some important info, so here goes --
The other day I upgraded to OS 10.4 from 10.3.9 on my iBook G4. This laptop has four user accounts. My printer is an Epson 740 that is connected by USB to an Airport Extreme base station.
After the upgrade, the printer wasn't responding. I followed the very helpful advice I got here (except for downloading most recent printer drivers, of which there are none past OS9). Everything seemed OK.
Today, none of the accounts will print unless I delete the printer, reset, reauthenticate, and add the printer back. This has to be done after each account change. I also ran the repair permission option in Disk Utility (on the HD, I presume). Every attempt to print is met with the appearance of the printer icon in the Dock with a big fat red exclamation point.
How can I reset the printer once and for all and not have to reconfigure it before and during every print job on each account? Please let me know if more info is needed. Thanks.
iBook Mac OS X (10.4) iMac Mac OS 9.1Sorry for the delay in replying, but this is my home computer and at work I have Windows. Anyway, while waiting to get back to you I cruised around here and found this:
http://docs.info.apple.com/article.html?artnum=301631
Apparently, there is a problem with Tiger and Epson 740's (probably other older printers too). Well, I tried the above and it worked.
Thanks again for your help. Good to know that it's available all the way from down under. AB

Message was edited by: HudiBefore deciding that you can't replace the drive yourself, visit the following site and find the step by step instructions for replacing the drive yourself:
http://www.ifixit.com/
If you see the instructions and feel that you can replace the drive yourself, you will save money that way. I'm not that familiar with modern iMacs, but I know it was very easy to replace the drive in my old iMac. It may not be as hard to do as you think. If you want extra help, you can post questions on the iMac forum.
If you still don't feel like it is something you can do yourself, try looking for an AASP (Apple Authorized Service Provider) in your area and see what it might cost to have the AASP do the replacement. Often an AASP can do a repair for less money than Apple, and they will usually be willing to install a drive that you have obtained elsewhere for a reasonable price. From what I have read on these forums, many people have used AASP's to install bigger and faster drives on their machines.
Definitely contact Western Digital about your drive. Usually WD drives come with a 3 year warranty, and if the drive fails before then, WD will replace the drive. KT has mentioned that the drive apparently is not under warranty, but might qualify for some sort of an upgrade. Before shopping elsewhere, check to see if this upgrade might entitle you to a very good deal on a replacement drive or something of that nature.
Good luck! -
IMac (still) freezes - console: What is "unknown SIGSEGV code 0" ?
Some weeks ago I was writing that my iMac started freezing at irregular intervals. At some point I thought that had found the error - unfortunately it still occurs, though.
Most of the time what happens is this:
* I draw with my Wacom Intuso 2 in Photoshop CS4. Suddenly nothing works anymore. The mouse Cursor can still be moved (sometimes not even that any more), and iTunes or webradio like Jango still plays what's stored in memory.
Neither Finder nor the dock, expose or spaces work any more.
* I can't put the computer in sleep mode. All I can do is force-power-off by holding power for 2 seconds
* I restart the computer and it works like nothing has happened. Sometimes it stays like that for 15 minutes sometimes I can work several hours or a full day without anything weird happening.
* there are no graphic glitches so I don't suspect the graphics chip (any more)
Just to get this out of the way:
I have an itel Based iMac 24", 3.06GHz DualCore, 2GB RAM.
It's a work machine: Adobe software, Cinema4D and ZBrush.
Worked absolutely flawless before. Works stable most of the time on Windows. Crashes are different from those on OSX if they occur though.
It all started shortly after my mac choked on a security update during install (which had me force-reset the computer the hard way). I installed the Update manually but the freezes still occur.
I have fixed access-rights (several times).
I have performed an intensive system check from the OS disc - nothing found.
I keep the system updated as soon as there are new updates available.
When monitoring the temperatures the only two values above what I think reasonable at times are Graphics (up to 72°C) and power supply (up to 75°C).
All other values are well within normal limits. The Mac stands freely and not to close to any wall. No heat source close to it, no window with too much sunlight either ....
I've already reset the PRAM. No effect.
Now I'm not too familiar with the console but checking the 'system.log' shows something like this very often:
* Feb 8 15:59:09 noname kernel[0]: unknown SIGSEGV code 0
* Feb 8 15:59:39: --- last message repeated 3 times ---
Is this something that could be crashing my mac?
Or does this mean nothing, really and the fault still lies somewhere else?
I'm really helpless, any more. My only hope is that it's no hardware malfunction and that my Mac won't die on me over the next few months.
Thanks for any help or advice.
Message was edited by: BlurryVision (typos)Some discussion and suggestions re. that error can be found in this thread on Adobe's forums:
http://forums.adobe.com/thread/300392
Whether or not that will help with your freezing issues I can't say. If not, I've seen anecdotal information that suggests issues with Wacom tablets, but again I can't say with certainty that it involved in your problem, but you might try working for a bit, if you can, with the tablet disconnected and see if that has any effect on the frequency of the freezes.
Hope this helps. -
I Fixed my iMac slow internet connection
I will share with you how I fixed my iMac slow internet connection and frequently lost connection. At first, I thought it was the Airport but then it wasn't the case. I also had a Dell laptop in the same basement and it was running as fast as I expected. Here are the steps:
1/ Open Airport link on the top right window > Open Network Preferences
2/
Click + to create new Network Name and Security, I chose WPA personal - less security than the WPA2- that is why it runs faster.
3/ Go mack to step 1 and select your new network name > Apply.
May iMac is now connecting to internet as fast as I would expected.
Good luckMy iMac internet connection is not faster but as fast as it used to be. I was using WPA2 and it was really good for a year and then I got disconnected or very slow. So I created the new network bearing the same old name but use WPA and did not delete the old one, some how everything is back to normal.

From the Top: How can I fix my iMac after failed 10.4.3 update?
I have an iMac G4 (hemispheric base) with 512 extra ram (from Apple). I used software update to upgrade to 10.4.3 After an apparently successful download, the computer refused to reboot. It would get to the desktop (with my usual icons visible) but then the spinning rainbow wheel would never stop.
== I tried various combinations of rebooting and unplugging. No luck.
== I tried using the Mac OSX install disk to repair permissions. No change.
== I tried using the install disk to repair the disk. It said I had an unrepairable error on my disk.
== I tried booting in safe mode. Computer would always turn itself off.
== I tried booting in single user mode. It would show a text screen but not really start.
== I tried using disk warrior ($100). It performed a lengthy repair. Computer now behaves a bit differently (e.g. in safe mode it gets to the log in screen and then hangs rather than turning itself off and when I try to start as usual I still see my custom desktop background but not my icons) but it still will not start. Also, frighteningly, the disk drive will no longer accept the OSX install dvd -- it just spits it out.
So, I feel stuck. I need some of the data on the computer (including some digital photos of hurricane Wilma damage for insurance purposes) but even if I were willing to do an install and erase, how can I, since the computer does not accept the dvd anymore?
I know I should have fully backed up and repaired the disk with the install disk ahead of the upgrade. I naively believed the download to be routine. However, I do need the data and do need the computer. Can anyone help?
Thanks to everyone.Hi
My Powerbook was the same. Only fix is to reinstall OSX from the install CD but be sure not to pick the Format and install clean. Once you boot with the install CD pick the preserve user data and settings.
On My machine the reinstall looked perfect. My network, email, files and all the programmes were all there. Most apps worked fine but Adobe CS2, Virtual PC and NetBarrier all needed reinastallation as they reported a few files or registration was missing. I went for the 10.4.3 upgrade again and it worked fine.
Good luck

How do I locate an iPad that never had a fixed apple ID associated with it?
If an iPad was lost or stolen and no fixed apple ID was set up for that device, and the device was reset to factory settings could that iPad still be found and would restting iPad delete the data plan off the device?
I ask this question because recently at my job it appears that the work iPad was lost and or stolen. It never had a fixed apple ID so we couldn't use iCloud to locate it. Managers just recycled through their personal apple ID's. it seems no one got a serial number for it, or the data number it used. My manager says they are tracking it through the data plan, and that she has something called high tech crimes involved in tracking it; but I thought if it was reset the iPad is pretty much lost since they failed to get all the info.
Is there a way to still track the iPad?
Ironically, I told Managment what to do to set the iPad up yet no one listened to me. They have the same issue with their current iPhone 4S. Guess some people will never learn lolReport to police along with serial number. Change all your passwords.

Question
when i search via mozilla i now have to go via mystart incredimail, which i thought i had uninstalled long ago, do you have any association with incredimail and is is now part of mozilla firefox 4 ?Hmmm, Norton extensions are broken again in Firefox 4.0.1. It seems that Norton didn't allow for Firefox 4.0 security updates when they updated their Firefox extension for Firefox 4.0. Norton says they'll have a fix in two weeks. A Norton user posted a fix in this forum thread.

I opened my account on the MacAir and have the new Mountain Lion showing i purchased. When I open my account on my other two machines it does not show. Any suggestions on why or how to fix?
iMac and Mac Pro
ThanksSADLY not as i downloaded an upgrad to my original PAGES/
i have in the meantim had to open www.icloud. then from there import the file that i am working on and then check on ipad if it uploaded/ yes it did.
but what a waste of time as it doesn not save any changes done automatically back in the cloud....
i am now downloading the new LION and hope that it will fix the problem
i cant find any other way. I was lead to believe that you wrote, it saved automatically, on to the cloud, you then opened anohter device in anotother country even, and the new file was there, waiting, in its latest version.......
and the same magic was supposed to happen in reverse.
It doesn't/
if i have to open a browser, go to www.icloud....why on earth did they not just leave us an icon to drop it in in that case?
I hope the new lion will help resolve the isssue/
any other ideas> keep em coming...thank you so much. -
I had to reboot my iMac, it froze... When I went to reboot it started up as usual... Made power sound, showed apple logo (white screen)... And pin wheel started after 3 to 4 mins., went to black screen with error messages. Rebooted 5x, shot off power source, disconnected external devices... Now won't go past pinwheel... Since it does not go to black screen, I cannot convey error messages... Please advise what I could try... Thank you... I have an iMac 2009... Upgrade operating system to new system this spring... Don.
It is guitardad's again... I read past topics on this issue... As I am not overly computer savvy, I want to be careful that I don't mess things up further... Of course the extended warranty is done... There is talk about booting from the system disc... I'm not sure if this is the first thing to do or not... Can the support community, advise me on what logical steps I should take ( in order) or direct me to a website and/ or you tube video that walks one safely through the processes... Once again thank you for reading and offering your advice... I am on fixed $$$ so I'm trying to avoid calling apple, unless I have no options and/or the suggestions do not resolve the issues... Tx again Don.

OS X Yosemite v10.10.3 Update - I had problems with my iMac after installing the previous update and I removed that update. Have there been problems associated with this update ?
I've been using it on all of my computer without any problems. Remember you won't see any positive comments here. Everyone here is complaining about a problem. If you want a good experience with any upgrade or update first make a backup from which you can boot the computer. If you are installing an update, like 10.10.3 for example, always download and install the Combo Updater - OS X Yosemite 10.10.3 Combo Update. Before you install any update or upgrade over an existing system you should do this:Repair the Hard Drive and Permissions:
Boot to the Recovery HD:
Restart the computer and after the chime press and hold down the COMMAND and R keys until the menu screen appears. Alternatively, restart the computer and after the chime press and hold down the OPTION key until the boot manager screen appears. Select the Recovery HD and click on the downward pointing arrow button.
Repair
When the recovery menu appears select Disk Utility and press the Continue button. After Disk Utility loads select the Macintosh HD entry from the the left side list. Click on the First Aid tab, then click on the Repair Disk button. If Disk Utility reports any errors that have been fixed, then re-run Repair Disk until no errors are reported. If no errors are reported click on the Repair Permissions button. Wait until the operation completes, then quit Disk Utility and return to the main menu. Select Restart from the Apple menu. -
I thought I had a problem with my Ipad in which I didnt, so I backed up my Ipad and restored it, but now Some of my apps that I have purchased are not available only the free version, not the purchased version. I would have to purchase again and it is not backed up into my Icloud either ?
I assume that you will have to set up as new since it will not let you restore from the backup. Then after you set it up, you can restore from the iCloud backup. The backup should not disappear be use you are setting this device up as new. Your backup should still be in iCloud.
However, after you activate the iPd and update the software, you will have to erase the device in order to restore from the Cloud backup, that is the only way to get to the iCloud backup.
Copied from the article that linked you to this discussion ....
Resolution
Update your device to the latest version of iOS to be able to restore the backup. -
I have .me and .mac email accounts on my iPhone 4. I thought I had successfully transitioned from MobileMe to iCloud, but something must be wrong. iCloud seems to work fine on my computer and, with the exception of two email accounts, seems to be fine on my phone. Can/should I delete the accounts on my phone and start over? It is somewhat of a nuisance to have two email accounts and double the amount of emails. The only thing different about the two iCloud accounts is the email addresses. Thanks.
Well, seems I managed to unscrew this...I deleted my iCloud mail account and reinstalled it on my phone. That got rid of the duplicate .me/.mac email accounts.

I unfortunately just got my IPhone 4s stolen.I thought I had the find my iPhone enabled but I didn't because I cannot locate the phone when I sign in ICloud.I have a password on the phone but i'm not sure if I turned on the option where the phone resets if you incorrectly put the password more than ten time. I immediately called my phone company (Verizon) and reported the phone stolen.So I know whoever took the phone cannot place calls or use the phone. But can they still access my data on the phone if they manage to unlock the phone? If so how can I erase all data on the phone so the thief can't access my personal information? is there any other way other than Find my IPhone to wipe off the data on the phone? I really don't want my personal information such as pictures, text messages, notes and social networks profile available to a stranger!!? Help please!!!
Hello thewrongway,
I'm sorry to hear about your phone! I understand the need for an active device. You are able to activate an old device and process an insurance claim for your iPhone 4s within 60days from the incident date. Keep in mind if the old phone is not a smartphone and you currently have unlimited data that feature will fall off. If you have a tier data plan no changes will be made. Please let me know if you have any additional questions. Thank you.

Can't seem to fix my iMac. Suggestions?
17inch 1.83 Ghz Intel Core Duo with 2GB Ram, running OSX 10.5.8. Software all updated via Software update, all maintenance scripts run via Cocktail.
(Internal optical drive failed a while ago so use an external Plextor drive instead.)
For months now, I've had a big problem with my iMac whereby the machine just hangs and won't even reboot. When this happens, Finder won't let me force quit any app that has hung (and it isn't always the same app that hangs) and even the dock freezes and becomes unresponsive.
The only way to get the iMac back when this happens is to power down and then reboot (something I hate doing).
I noticed this tended to happen when Time Machine was "Preparing to Backup" but not any more, it just randomly and very often hangs.
As of now, my iMac is unusable and am having to make do with my old Macbook which is hopelessly underspeced for what I need to be doing.
Over the weekend, the iMac failed completely.
To cut a long story short, I have just completely reinstalled OSX 10.5.8 by hooking the iMac to the Macbook via Firewire, reformatting the iMac via Disc Utilities on the Macbook then installing OSX 10.5.8 using the Macbook running the install disc and targeting the iMac as an external firewire drive. I then used Utilities on the install disc to reload the last configuration of the iMac from the last Time Machine backup.
However, my iMac is STILL randomly freezing and behaving just as before.
Have any of you experts out there any other suggestions for me to follow? I need help here...
Thanks!Forgive me asking a dumb question but I've never done this before... Where will I find the "Zero all data" option and how do I do this? I'm guessing it's part of the Erase and Install protocol. Am I right?
When you are booted from your install disc, open the Disk Utility to reformat the drive. In there you will see a tab called "Security Options." You can select "Zero all data" in there.
And presumably, I just copy over the current Preferences folder which is in User/Library and then just over-write the new one once the new install is complete. Is this right?
Correct. Repair your permissions before and after the move also.
