Mac getting slower and slower, HELP!

well, i know that it is not normal for mac to be slow but this actually happens to me when i have only safari and the finder open. i checked and i have only the norton anti virus at the back ground running as well as the messenger for mac. Is it a problem with the soft ware updates? Because when i 1st got it, (feb 2008, but last year model), it was running as fast as apple had declared. But it is running very slow now, which is as good as windows. If i go down to apple and fix it or do i have to pay for any problem even if my warranty is still covered (expires at dec 08)
Thanks

Go down there before you 90 days are up and tell them the Norton AV ware is causing havoc on your system, remove it. Basic steps to speed up your computer is repairing permissions from Utilities, reset the PRAM,NVRAM:
Resetting PRAM and NVRAM
Shut down the computer.
Locate the following keys on the keyboard: Command, Option, P, and R. You will need to hold these keys down simultaneously in step 4.
Turn on the computer.
Press and hold the Command-Option-P-R keys. You must press this key combination before the gray screen appears.
Hold the keys down until the computer restarts and you hear the startup sound for the second time.
Release the keys.
Next install the Leopard disk when the first aid i is is the menu, chose it, first aid, repair your drive.
These are all steps to help performance, post back with your results. This way we can try other things. Nothing I gave you to do is harmful to your system.

I have a mac 10.5 and need help figuring out how to change my email settings so it does not automatically delete my inbox every 30 days. How to I adjust the mail settings?

I think it must be an IMAP account then, & in Mail>Preferences>Accounts>Advanced>Keep copies for Offline viewing:>Don't keep copies, then on the Server, or maybe it's just this one itself, but on the Server you have a setting to remove eMails after 30 days.
If it's a POP account we'd have to investigate that... but you didn't say so I'm guessing here.

Mac gets slow after installed OS X 10.5 Leopard

Dear All,
Hope you had a great Christmas!!
As I mentioned, after I upgrade my OS X10.4 to 10.5 Leopard my Mac gets very slow to start the machine. Normally takes less than minute to start to operate, but now it takes long time to load.
First I thought it because of my hard drive running low space so I moved most of files to my external hard drive, left 57G free space but nothing is improved.
Any ideas why? Anyone knows how to improve the speed?
Thanks for your helps!
Michael

Sounds plenty sufficient to me.
according to a quick google search, mdworker is related to spotlight, indexing what/where/content of files.
there may be other ppc stuff lurking, especially if this is not your first mac and you used migration wizard to move from a PPC to intel mac.
Thats what I did...and was quite unhappy with the perfrmance.
I finally found a QT plugin that was (one of the things) killing my quads performance. (select the plugin, do a get info, it'll tell you if its PPC or universal) QT plugins do not show in activity monitor.
Found another firefox plugin that did the same.
activity monitor shows relative processor usage.
with no programs open other than activity monitor, whats using a high percentage of processor?
Oh, and if you have an old copy of Norton utilities, that will cause all sorts of problems. The only Norton/symantec product that is still OK to use is their anti-virus, and then, only version 8 or higher. System saver and all the other parts of NU just cause problems under X.
As longs as you have at least 15% of your disk free, you should be OK there.
Much below that, and the system will complain and start doing strange things.

My mac gets slow when I play music from my iTunes library

Hi, aproximately six months ago I noticed that everytime I play music from my iTunes library that its stored in my 27" iMac's hard drive, the computer gets slow, the images start to flicker, the animatios on the dock and the one when u minimize or maximaze the windows, also flicker. As soon as I close iTunes the computer works fine again. When I play music from a CD this doesn't happen.
I've taken the iMac to two service providers along theese 6 months and neighther have been able to fix the issue. What they have diagnozed is an issue with the hard drive which has been changed 4 times already.
What could be the issue?

Basic troubleshooting from the User's Guide is reset, restart, restore (first from backup then as new). Try each of these in order until the issue is resolved.

Mac Mini Power and Standby help - Boot camp XP

Hey guys, I am an apple freak. Got a mac pro,mac book pro and now a mac mini! I upgraded the ram to 2gb.
I cant figure out why I cant get the computer to come out of standby correctly with xP? the screen doesnt come up at all, though sound seems to work. I have it attached to my plasma via dvi, and was plan on using it as a media center (sagetv) system.
I also was wondering, if I just forget about the whole standby issue, how much energy does this thing take? I mean, will going into standby really save that much energy?
Thanks
Mo

Hi,
For issues with Boot camp it is best to ask in the offical Boot camp forum (http://discussions.apple.com/forum.jspa?forumID=1165)

Mac Mini slow - Help

Looking for some help. I am running a 2010 Mini, with Lion 10.7.5.
I have 8GB of memory installed. Contantly find that the computer slows down with only 2 Google Chrome tabs and maybe a couple other apps. What can I do to troubleshoot the root cause of my problems?
Couple screen caps from my system:

This comment applies to malicious software ("malware") that's installed unwittingly by the victim of a network attack. It does not apply to software, such as keystroke loggers, that may be installed deliberately by an attacker who has hands-on access to the victim's computer. That threat is in a different category, and there's no easy way to defend against it. If you have reason to suspect that you're the target of such an attack, you need expert help.
All versions of OS X since 10.6.7 have been able to detect known Mac malware in downloaded files. The recognition database is automatically updated once a day; however, you shouldn't rely on it, because the attackers are always at least a day ahead of the defenders. In most cases, there’s no benefit from any other automated protection against malware. Starting with OS X 10.7.5, there is another layer of built-in malware protection, designated "Gatekeeper" by Apple. By default, applications that are downloaded from the network will only run if they're digitally signed by a developer with a certificate issued by Apple. Applications certified in this way haven't actually been tested by Apple (unless they come from the Mac App Store), but you can be sure that they haven't been modified by anyone other than the developer, and his identity is known, so he could be held responsible if he knowingly released malware. For most practical purposes, applications recognized by Gatekeeper as signed can be considered safe. Note, however, that there are some caveats concerning Gatekeeper:
It doesn't apply to software that comes packaged as an installer. Treat all third-party installers with caution.
It can be disabled or overridden by the user.
It can be bypassed by some third-party networking software, such as BitTorrent clients and Java applets (see below.)
It only applies to applications downloaded from the network. Software installed from a CD or other media is not checked.
For more information about Gatekeeper, see this Apple Support article. Notwithstanding the above, the most effective defense against malware attacks is your own intelligence. All known malware on the Internet that affects a fully-updated installation of OS X 10.6 or later takes the form of so-called "trojan horses," which can only have an effect if the victim is duped into running them. If you're smarter than the malware attacker thinks you are, you won't be duped. That means, primarily, that you never install software from an untrustworthy source. How do you know a source is untrustworthy?
Any website that prompts you to install a “codec,” “plug-in,” or “certificate” that comes from that same site, or an unknown one, is untrustworthy.
A web operator who tells you that you have a “virus,” or that anything else is wrong with your computer, or that you have won a prize in a contest you never entered, is trying to commit a crime with you as the victim. [Some reputable websites did legitimately warn users who were infected with the "DNSChanger" malware. That exception to this rule no longer applies.]
“Cracked” copies of commercial software downloaded from a bittorrent are likely to be infected.
Software with a corporate brand, such as Adobe Flash Player, must be downloaded directly from the developer’s website. No intermediary is acceptable.
Java on the network (not to be confused with JavaScript, to which it's not related) is always a potential weak spot in the security of any operating system. If a Java web plugin is not installed, don't install it unless you really need it. If it is installed, you should disable it (not JavaScript) in your web browsers. Few websites have Java content nowadays, so you won’t be missing much. This setting is mandatory in OS X 10.5.8 or earlier, because Java in those obsolete versions has known security flaws that make it unsafe to use on the Internet. The flaws will never be fixed. Regardless of version, experience has shown that Java can never be fully trusted, even if no vulnerabilities are publicly known at the moment.
Follow these guidelines, and you’ll be as safe from malware as you can reasonably be.
Never install any commercial "anti-virus" products for the Mac, as they all do more harm than good. If you need to be able to detect Windows malware in your files, use the free software ClamXav — nothing else.
Why shouldn't you use commercial "anti-virus" products?
Their design is predicated on the nonexistent threat that malware may be injected at any time, anywhere in the filesystem. Malware gets into the system by being downloaded, not by materializing from nowhere.
In order to meet that nonexistent threat, the software duplicates low-level functions of the operating system, which is a waste of resources and a common cause of instability and poor performance.
By modifying the system at a low level, the software itself may create vulnerabilities that could be exploited by malware attackers.
ClamXav doesn't have these drawbacks.

Mac Getting Slower...

Hi,
I have a 8 Core Mac Pro, with 10 Gb of Ram. I did a clean restore, and manually installed the programs. I'v had SL for a week, and I'v noticed a decrease in speed. At startup, its slower and I have unchecked everything at login menu. Programs that used to take 10-15 seconds to open, like Photoshop are now taking double that time or more, (the first time opening it).
I'v read that if you hold 6 & 4 while restarting the computer, the mac then runs in 64 bit. Since I do have all the qualifications to run in 64, would I benefit from this, since most of the programs I use are not meant to run in 64?
The sluggishness has happened to me before in 10.5. After every clean restore it would go slower as time went by. I was told to disable all login items, and I did, which sped up my mac for a while. I can't understand why this happens, I don't install many 3rd party apps that are unknown. I don't feel like my mac is really using all my processors and ram as best as it could as it gets stuck for a half a minute at times with SL. I repaired permissions, but nothing seems to help.
Any ideas,
Zevie

There's little advantage to running in the 64-bit kernel. Any third-party software using 32-bit plug-ins or extensions will not work, and only third-party applications written for 64-bits can take advantage of it - as of now there are very few of those. And, there's little benefit to the ability to use large amounts of RAM since the none of the current Mac models can even address the maximum enabled in the 32-bit kernel.
There are likely other reasons for your experience of slowness (unless it's simply perceptually in your mind.) You might open Activity Monitor, select All Processes from the Processes drop down menu, click twice on the CPU column header to display in descending order. Look for any entry use a large amount of CPU time. You may have some program corruption, cache or preference file corruption that could be causing the slowdown. Also look for any applications listed that are running via Rosetta - PPC only applications - as they will run slower. For example any pre-CS4 applications from Adobe.
Repairing permissions is not going to make a computer run faster. Repairing the hard drive won't either, but it may fix disk errors if any that can slow down disk accesses. But this doesn't cause a program to run slower.
I know you said you did a clean "restore" but that is not a clean "install." I suggest the latter. Boot from the SL DVD, use Disk Utility to erase the hard drive, then install SL from scratch.

Now i finally got a different report back from windows error reporting saying a "Non Compatable BIOS is the cause " here is the error report screeny i took and uploaded to flickr http://farm4.static.flickr.com/3538/3349882297_4a3194e3df_b.jpg and this is another screeny in flickr of my BIOS in MSI Info View http://farm4.static.flickr.com/3445/3349882397_ef282a33d2_b.jpg , i believe i have the newest BIOS installed and the correct one also and have been running that version for along time . When i first setup this system i could not get my Q9550 to boot at all with this mobo till i updated the bios to the P0B6 but have never had it stable from BSOD . My Specs are Q9550 "Core 2 Quad Yorkfield SLAWQ Q9550 333 2.83 12M " / MSI P7N Platinum 750i SLI / OCZ Vendetta CPU cooler / 4GB- 4x1GB OCZ FLEX DDR2 1150 / OCZ GameXtreme 1010W / 2x - XFX GTX260 Black Edition in SLI / 1TB Seagate HD .

I suggest that you clear CMOS and use flash it to the BIOS v1.1 under the MSI website for your board and see how it goes.

LOL thats funny !!!!! 1.1 is what came installed on the mobo and is not compatable with the Q9550 it will never boot to bios using 1.1 with a quad core ! Thats the first problem i had thats why i explained all the steps i had to go through to get this mobo / cpu to boot with the help from MSI tech support !

Sync to Entourage and Not Mac Address book and ical HELP

I just got a brand new MacBook Pro (no more PC)!!!! My I Sync my phone and it put all the data in ical and address book. I use Entourage and thats where i would like all my info to go. how do i set up itunes to go to entourage and not the apple sofware.
And Can i sync via bluetooth?
thanks you
Brad "new Mac guy" Glaberson
Message was edited by: bradley Glaberson

The isync database, as I called it, is really just the master database from which ical, address book, bookmarks, etc., are stored, and it's used for syncing with the .mac service. Entourage can sync with it too, just go to the Entourage menu, choose Preferences, and look under General Preferences for Sync Services. Then check the boxes you want -- I just wanted the contacts to be the same in Entourage and Address Book so I only checked that one. The calendar is kind of funky because iCal uses separate calendars to group events, and I think if you check that box, iCal will then get a new calendar called Entourage, or something like that, in which all the Entourage events will go to and from. That is, I think Entourage will sync only with that iCal calendar, but I could be wrong about that since I don't use it.
Once you check the contacts box, Entourage will populate with all the contacts in your Address Book, and I think if you don't already have contacts there (that is if you've only been using Entourage for your contacts) then it will ask you if you want to put all your Entourage contacts into Address Book. I just don't remember.
Surely someone else out there is more familiar with this, but it should get you started.

Mac gets slowly and stops at the end. Reboot is necessary until next shutdown. What is the problem?

I face the problem that since some week my iMac gets very slowly and stops working at a time. Any idea what I could do to avoid that
thanks caparica

Apple warns about using an older version pre-10.4.3, with later versions of Tiger. you should be able to just boot to Single User Mode and at the command prompt follow the directions for running
/sbin/fsck -fy
to repair the boot drive.
Then, when you can, clone (backup your system) to another disk drive twice, once for your "working system" and another which is just your emergency system. That way, if, say 10.4.7 doesn't go as planned, you also have a backup.
Sometimes you need a 3rd party utility like TechTool Pro, Disk Warrior, Drive Genius or something.
Also, deleting the cache files/folders can help. And Applejack can be run along with fsck from S.U.M. (though I only use manual functions, and I never ever run it in auto mode).
How about a Safe Boot by holding down the Shift key which would help rule out startup items or 3rd party extensions?
If you do see power outages, and don't have UPS, that can help protect modem, ethernet port, and your system.
Boot to Tiger DVD, use Disk Utility Restore, and copy your boot drive to another drive. Always have a backup before working on trying to repair a drive.

Just Bought New Mac Mini Server and Need Help on Migrating Old Single User

This is for my home / home office The issue is I was unable to connect to my old computer using migration assistant for some reason, but I didn't want to go down a rabbit hole to figure it out.
I would like to transfer all of my applications and prefs / settings to the new machine and I was thinking about using a synching program to do it so I wouldn't mess with the SL Server settings. I suppose I could do this manually but am concerned some hidden files or settings may not get moved properly. I am able to mount my old hard drive on the new mini so I just need a strategy. Thanks.

Good question - my angst is subsiding as I type. I was concerned that my preferences and other application linked things like Application Support were the same as it was, but I suppose if I have to mess a bit with it upon opening or reinstalling a program is the worst thing that will happen. After going thru the list of programs I realize that like most people I regularly use about 15% of the things in my Applications folder. The biggest hassle is Adobe CS4 which I need to get reauthorized by Adobe and this could only have been solved if I de-authorized it before blowing out my earlier computer. Luckily that is worst issue I am encountering.

My Mac gets freezing

my Mac gets freezing and getting some strange lines across the screen! I have run Sophos and nothing is detected. Can you help

It's not a virus! Your GPU may be failing. Do a
SMC RESET
http://support.apple.com/kb/HT3964
Shut down the computer.
Unplug the computer's power cord and ALL peripherals.
Wait 15 seconds.
Attach the computers power cable.
Wait another 5 seconds and press the power button to turn on the computer.
It is the 5 second timing that initiates the reset.

My MAC is running very slow and i am a complete novice and don't know what to do. i have had my Mac since 2008 and its probably in a mess. if you can help i would be grateful. EtreCheck version: 1.9.15 (52) Report generated 8 September 2014 09:09:26

My MAC runs very slow. Rainbow wheel every time i try to go somewhere. Im a complete MAC novice. Only really use it for iTunes and email. the odd document here and there. The odd spreadsheet. Was brought up on a PC. I would imagine my system is in mess. I think i downloaded that Mackeeper which i have just discovered was not a good idea. I found a thread about EtreCheck and it suggested i posted the report of my machine which i have done.I only have 2GB of space. Not sure how much i have left. My wife keeps putting photos on here like they are going out of fashion. Bought the machine in 2008 because everybody said you have a MAC. I've never really got to grips with it but at least it worked. Now it does not run very well at all. That spinning wheel is driving me mad. HELP please, never ever used a forum light this either so please go gentle on me. Cheers Paul

1. This procedure is a diagnostic test. It changes nothing, for better or worse, and therefore will not, in itself, solve the problem. But with the aid of the test results, the solution may take a few minutes, instead of hours or days.
Don't be put off merely by the seeming complexity of these instructions. The process is much less complicated than the description. You do harder tasks with the computer all the time.
2. If you don't already have a current backup, back up all data before doing anything else. The backup is necessary on general principle, not because of anything in the test procedure. Backup is always a must, and when you're having any kind of trouble with the computer, you may be at higher than usual risk of losing data, whether you follow these instructions or not.
There are ways to back up a computer that isn't fully functional. Ask if you need guidance.
3. Below are instructions to run a UNIX shell script, a type of program. As I wrote above, it changes nothing. It doesn't send or receive any data on the network. All it does is to generate a human-readable report on the state of the computer. That report goes nowhere unless you choose to share it. If you prefer, you can read it yourself without disclosing the contents to me or anyone else.
You should be wondering whether you can believe me, and whether it's safe to run a program at the behest of a stranger. In general, no, it's not safe and I don't encourage it.
In this case, however, there are a couple of ways for you to decide whether the program is safe without having to trust me. First, you can read it. Unlike an application that you download and click to run, it's transparent, so anyone with the necessary skill can verify what it does.
You may not be able to understand the script yourself. But variations of the script have been posted on this website thousands of times over a period of years. The site is hosted by Apple, which does not allow it to be used to distribute harmful software. Any one of the millions of registered users could have read the script and raised the alarm if it was harmful. Then I would not be here now and you would not be reading this message.
Nevertheless, if you can't satisfy yourself that these instructions are safe, don't follow them. Ask for other options.
4. Here's a summary of what you need to do, if you choose to proceed:
☞ Copy a line of text in this window to the Clipboard.
☞ Paste into the window of another application.
☞ Wait for the test to run. It usually takes a few minutes.
☞ Paste the results, which will have been copied automatically, back into a reply on this page.
The sequence is: copy, paste, wait, paste again. You don't need to copy a second time. Details follow.
5. You may have started the computer in "safe" mode. Preferably, these steps should be taken in “normal” mode, under the conditions in which the problem is reproduced. If the system is now in safe mode and works well enough in normal mode to run the test, restart as usual. If you can only test in safe mode, do that.
6. If you have more than one user, and the one affected by the problem is not an administrator, then please run the test twice: once while logged in as the affected user, and once as an administrator. The results may be different. The user that is created automatically on a new computer when you start it for the first time is an administrator. If you can't log in as an administrator, test as the affected user. Most personal Macs have only one user, and in that case this section doesn’t apply. Don't log in as root.
7. The script is a single long line, all of which must be selected. You can accomplish this easily by triple-clicking anywhere in the line. The whole line will highlight, though you may not see all of it in the browser window, and you can then copy it. If you try to select the line by dragging across the part you can see, you won't get all of it.
Triple-click anywhere in the line of text below on this page to select it:

Copy the selected text to the Clipboard by pressing the key combination command-C.
8. Launch the built-in 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.
Click anywhere in the Terminal window and paste by pressing command-V. The text you pasted should vanish immediately. If it doesn't, press the return key.
9. If you see an error message in the Terminal window such as "Syntax error" or "Event not found," enter
exec bash
and press return. Then paste the script again.
10. If you're logged in as an administrator, you'll be prompted for your login password. Nothing will be displayed when you type it. You will not see the usual dots in place of typed characters. Make sure caps lock is off. Type carefully and then press return. You may get a one-time warning to be careful. If you make three failed attempts to enter the password, the test will run anyway, but it will produce less information. In most cases, the difference is not important. If you don't know the password, or if you prefer not to enter it, press the key combination control-C or just press return three times at the password prompt. Again, the script will still run.
If you're not logged in as an administrator, you won't be prompted for a password. The test will still run. It just won't do anything that requires administrator privileges.
11. The test may take a few minutes to run, depending on how many files you have and the speed of the computer. A computer that's abnormally slow may take longer to run the test. While it's running, there will be nothing in the Terminal window and no indication of progress. Wait for the line
[Process completed]
to appear. If you don't see it within half an hour or so, the test probably won't complete in a reasonable time. In that case, close the Terminal window and report what happened. No harm will be done.
12. When the test is complete, quit Terminal. The results will have been copied to the Clipboard automatically. They are not shown in the Terminal window. Please don't copy anything from there. All you have to do is start a reply to this comment and then paste by pressing command-V again.
At the top of the results, there will be a line that begins with the words "Start time." If you don't see that, but instead see a mass of gibberish, you didn't wait for the "Process completed" message to appear in the Terminal window. Please wait for it and try again.
If any private information, such as your name or email address, appears in the results, anonymize it before posting. Usually that won't be necessary.
13. When you post the results, you might see an error message on the web page: "You have included content in your post that is not permitted," or "You are not authorized to post." That's a bug in the forum software. Please post the test results on Pastebin, then post a link here to the page you created.
14. This is a public forum, and others may give you advice based on the results of the test. They speak only for themselves, and I don't necessarily agree with them.
