Performance and instability trouble with intel iMac after 10.4.8

Hi all,
I have a 20" intel (Core Duo) iMac. Everything was super fast and nice since I bought it last February.
I recently "software updated" to 10.4.8 and since then it seems slower, groggy, and Safari crashes regularly.
Is this a known issue or is it just me? Is there anyway to uninstall 10.4.8? Or, can anyone recommend a utility to help diagnose the problem?

Hi boxlight,
No, you are not the first to mention the issues you are now experiencing with the 10.4.8 update...
Here's what I would try: http://www.apple.com/support/downloads/macosx1048comboupdateintel.html - you can run the Combo Update and see if that "fixes" any issues. There have been posts re: using the Combo Update which ended up fixing some software glitches...
You can also go here: http://www.thexlab.com/faqs/maintscripts.html#Anchor-Manually-49575 - I use the Terminal method to run the Maintenance Scripts and my Mac runs better than new...
Good luck, Rick

Trouble with intel iMacs and OD binding

When setting up 12 of our new iMacs at school this fall, I've run into a problem. Once bound to our OD server, the machines will hang intermittently during boot (before a login screen).
In this lab we have 16 eMacs running 10.4.7, and now 12 intel iMacs running 10.4.7. The OD server is 10.4.7 server.
All machines were first bound to our school's AD server and tested. All logged in for two days of students.
Then today the OD server was finally up and running for mcx settings. The 16 eMacs were added without problem. The iMacs were added, but now if they are restarted they often hang. Rebooting them may fix it. Sometimes they need to be rebooted several times.
Once an intel iMac makes it to the log in screen they act as they should. They authenticate first to AD, then get whatever mcx settings they need from the OD.
Tried: clearing out all bindings and caches and starting fresh.
Note: The OD master is not bound to the AD, The OD server's kerberos record is disabled as outlined in this help article (http://docs.info.apple.com/article.html?artnum=300765)
Any help?

You don't really need the old OS 9 printer utility - other than to know how many prints your printer has made. It prints fine in OS X at it's best resolution.
I am using this printer everyday w/ an intel iMac.
Of course ... you need to connect your 16/600 to your network through an ethernet hub.
In System Preferences - Network - make AppleTalk active.
Then go to the Print & Fax preferences and set up new printer.
The 16/600 will show up there.

Dual networks, express and extreme problem with Intel iMac accessing both

I have two airport networks setup to two different ISP's. One is setup using two Airport Expresses with a printer hung off one. The other is setup with an Airport Extreme with two USB disks.
I have a G4 iBook 14" laptop and a MacPro 17" Intel laptop that see and can bee switched between both networks utilizing Internet Connect. They are running OS X 10.4.11.
The other system is an Intel iMac 20" (late 2006) running OS X 10.5.1. The only wireless network it sees is the Airport Extreme. This is frustrating because I want to be able to switch to the Express network to print and cannot get the iMac to recognize the network. Before upgrading to 10.5.1, I could, on occasion, see the other network, now I can not.
Has anyone experienced this and is there a way to fix it? I believe it is operating in 802.11n, but have no way to verify this.

I miss posted this in windows. I reposted this in the Airport Extreme.

Success with iDefrag and DiskWarrior on my Intel iMac! (indirectly)

Had some very good success using iDefrag and DiskWarrior on my intel iMac, both of which do not run directly on the intel platform yet. As I had observed a gradual (modest) slow-down over the course of the past month since I got my iMac, I couldn't help but try to figure out a way to defrag and optimize the hard drive since I had over 125GB (including quite a few large media files, and a couple system updates, both of which tend to cause fragmentation). So, after doing two independent backups on separate external HD's, I ran iDefrag on my iBook and defrag/optimized the iMac's hard drive using Target Disk Mode. As expected, the hd was VERY fragmented - and the process took overnight to complete. Being as careful as possible to ensure no problems, I then ran verify disk and repair permissions on the iMac's hard drive, and no problem. Did notice a very meaningful increase in responsiveness and speed on the iMac, even more than I would have expected. Since I historically always ran DiskWarrior after doing this exercise on my PPC mac's, I decided to attempt the same here. Since I (and others on this board) have been unsuccessful in running DW3.03 using the iMac in Target Disk Mode, I decided to update backup drive #1 post-iDefrag, and was then able to mount this drive (backup#1) and run DiskWarrior on it from the iBook. No problems were detected which was great news, but the I had it write the new index/directory files. I then sync'd back to my iMac's hard drive (from backup#1 to iMac HD) and observed that a number of files were updated most likely as a result of the updated directory/index files from running DW (I use FolderSynchronizer to sync). So keeping backup#2 of the pre-iDefrag/DiskWarrior for a while, but so far so good, and a very meaningful improvement in performance. So the experiment seems to be a success.
DISLAIMERS: If anyone does "try this at home" please backup and re-backup before attempting. In addition, please note that Coriolis is in the process of developing an intel build for iDefrag and probably recommended in general to wait for this update.

Thanks for this posting and the good advice. I put in some time chasing the 801.57 gb limit before finding this thread that steers in the direction I see now I must persue, a new enclosure (modern day version rather than 5 year old technology -- yes, the old external drive has the Oxford chipset mentioned repeatedly in other threads) to go with my new drive. Would have been better off $$-wise to have purchased a complete unit, but this is so much more fun on a Monday evening.
Great being here with you all!

I am feeling so ripped off right now. I have wanted a Mac for years and believed the hype about it's stability and I have had more trouble with this Imac 2011 than I have ever had with a pc. It locks up with several software products from APP store.

I am feeling so ripped off right now. I have wanted a Mac for years and believed the hype about it's stability and I have had more trouble with this Imac 2011 than I have ever had with a pc. It locks up with several software products from APP store. I have already had to have a technician to look at it and really couldn't figure out what the deal was. I was told that the APP store software should give me no problems but the truth is that it locks up on the software. This machine is only 4 weeks old and I am using 37 g on a 1 T hard drive. There is no reason for it to be locking up. Also, when I try to use the help program, it always tells me that I am not connected to the internet even though I have used both the mail program and the browser with no problem just before that. I successfully used the help program on my pc lots of times. I did not need a $2000. plus machine to just get email. I just wanted to unload on somebody that might understand my pain and after checking out this site...I think there is a few of you out there.

I was told that the APP store software should give me no problems but the truth is that it locks up on the software.
The apps downloaded from the Mac App Store are written by third party developers, not Apple. If you have problems with those apps you need to visit the support area for their websites. Launch the App Store, locate the app name. You should see a support link.

Go to ~/Library/Preferences. Move the com.apple.helpviewer.plist file from the Preferences folder to the Trash. Restart your Mac, try the Help menu.
If you need help finding that file, hold down the Finder icon in the Dock then click: New Finder Window. From the menu bar top of your screen click: Go > Go to Folder. Type this in exactly as you see it here: ~/Library/Preferences/com.apple.helpviewer.plist That will take you right to that file.
(.plist) files stores information about a particular app or in this case, the Help viewer. Often times deleting the .plist file resolves the issue.
It's fine to "unload"... we understand that you expect your iMac to be stable but there are times when things go awry. That's why we have these forums so that you can you get help.

HT4623 Is anybody having trouble with your ringer after installing OS 6.0 and using the new GPS system?

Is anybody having trouble with your ringer after installing OS 6.0 and using the new GPS system?

The good (?) news is many people are have OS 6.0.1 wifi problems.
I could not connect to my home network. What eventually worked for me (twice now), though it makes no sense, is to go to the particular connection you want to use, hit the little blue arrow on the right to get the details screen. Scroll down to the bottom and change "HTTP Proxy" from "None" to "Auto". Then leave the "URL" field that pops up blank.
This should not work. However, it has for me where many other suggestions have not.
*shrug*
Best of luck.

I have an iMac and a MacBook with Intel Core 2 Duo processors. I realize that this is within the stated requirements for Lion. However was wondering if by migrating to Lion this will result in too much demand on processor resources, thus a slower machine than using Snow Leopard?

Which iMac? Which Macbook? Both have had several model
itertations, even within the framework of a Core2Duo processor.
With that said, I have an early 2009 iMac 24", with 2.66 GHz
Core2Duo with 8 gig of RAM, and in my opinion, seems to be running
smoother and faster with Lion.

HT204490 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 ?

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.

How to Perform an Archive and Install
An Archive and Install will NOT erase your hard drive, but you must have sufficient free space for a second OS X installation which could be from 3-9 GBs depending upon the version of OS X and selected installation options. The free space requirement is over and above normal free space requirements which should be at least 6-10 GBs. Read all the linked references carefully before proceeding.
1. Be sure to use Disk Utility first to repair the disk before performing the Archive and Install.
Repairing the Hard Drive and Permissions
Boot from your OS X Installer disc. After the installer loads select your language and click on the Continue button. When the menu bar appears select Disk Utility from the Installer menu (Utilities menu for Tiger, Leopard or Snow Leopard.) After DU loads select your hard drive entry (mfgr.'s ID and drive size) from the the left side list. In the DU status area you will see an entry for the S.M.A.R.T. status of the hard drive. If it does not say "Verified" then the hard drive is failing or failed. (SMART status is not reported on external Firewire or USB drives.) If the drive is "Verified" then select your OS X volume from the list on the left (sub-entry below the drive entry,) click on the First Aid tab, then click on the Repair Disk button. If DU 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 DU and return to the installer. Now restart normally.
If DU reports errors it cannot fix, then you will need Disk Warrior and/or Tech Tool Pro to repair the drive. If you don't have either of them or if neither of them can fix the drive, then you will need to reformat the drive and reinstall OS X.
2. Do not proceed with an Archive and Install if DU reports errors it cannot fix. In that case use Disk Warrior and/or TechTool Pro to repair the hard drive. If neither can repair the drive, then you will have to erase the drive and reinstall from scratch.
3. Boot from your OS X Installer disc. After the installer loads select your language and click on the Continue button. When you reach the screen to select a destination drive click once on the destination drive then click on the Option button. Select the Archive and Install option. You have an option to preserve users and network preferences. Only select this option if you are sure you have no corrupted files in your user accounts. Otherwise leave this option unchecked. Click on the OK button and continue with the OS X Installation.
4. Upon completion of the Archive and Install you will have a Previous System Folder in the root directory. You should retain the PSF until you are sure you do not need to manually transfer any items from the PSF to your newly installed system.
5. After moving any items you want to keep from the PSF you should delete it. You can back it up if you prefer, but you must delete it from the hard drive.
6. You can now download a Combo Updater directly from Apple's download site to update your new system to the desired version as well as install any security or other updates. You can also do this using Software Update.

Hi, having trouble with my iMac on startup. Background screen appears, but no icons,

Having trouble with my iMac- on startup, the background screen appears, but no icons. The spinning beach ball appears for quite a long while, then when the icons finally come up, when I open a finder window, the only icons to appear are the Network and Macintosh HD icons. I've tried to repair disk permissions: this came up with heaps of errors, which it then fixed, but the original problem remains.
Any suggestions on how to fix this?
thanks

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 and log in as Guest. For instructions, launch the System Preferences application, select Help from the menu bar, and enter “Set up a guest account” (without the quotes) in the search box. Same problem(s)?
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 in Mac OS X 10.7 or later, then you can’t enable the Guest account. 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.
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:
Be sure your Mac is shut down.
Press the power button.
Immediately after you hear the startup tone, hold the Shift key. The Shift key should be held as soon as possible after the startup tone, but not before the tone.
Release the Shift key when you see the gray Apple icon and the progress indicator (looks like a spinning gear).
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 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.
Same problem(s) in safe mode?
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.

There are some patterns of crashes that suggest possible causes and fixes; some users report crashes when FCPX is in the process of loading; others while importing/exporting, etc. Asking to narrow the list of possibilities.
Suggest starting with three things:
1) Update the software from the APp Store if need be.
2) Trash preferences.
3) Repair permissions.

I downloaded mountain lion and then iPhoto '11 in order to tap into iCloud capabilities with all of my devices. (My Mac was outdated in regards to operating platform to do this). After installing iPhoto 11, I had to repair and rebuild my library of photos. However, after doing this, all of my albums were jumbled and, while I can see the image thumbnail, when I click on the thumbnail, and error that looks like a black triangle and gray exclamation pops up as opposed to the larger hi def image I want to view.
