Our Mac is running very slowly. What do we do?
We have a Mac desktop circa 2003 and it is starting to run very slowly. Any things we can try to speed it back up?
Start by working out what model you have.
Apple Menu > About this Mac > More info button. Look for the 'Model Identifier'. Also check the OS version that appears in the first dialog.
iMacs from around 2003 cannot run 10.6.8, so something is not correct.
Many things could be the reason for slowness - you need to indicate what is wrong, when it happens what apps are being used.
If you have system disks backup this Mac & run Disk Utility from the install DVD/CD to see if the disk is OK, repair the boot disk. It also helps to remove ALL non Apple USB, Firewire & other devices to see if any attached devices cause the slowness.
It could also be that hardware is failing, so a backup is essential. The original grey install disks will have Apple hardware test which may indicate a fault (or may just report an erroneous message). Record any error numbers & re run the tests several times (issues can depend on temperature). The instructions should be printed on the install disk (normally hold D @ startup with it inserted).
If you have spare external HD's it may be simplest to install a clean version of OS X to see if that boots & is stable. Firewire may be the fastest connection type on older iMacs.
I assume this Mac has been running this OS for a while now? Have you got a full backup of it? How much is installed on it? Are you fastidious about updating software & removing things you don't use?
If any bits are unclear ask & we may be able to dig out links that explain parts of it, but it's important to know the model & OS version accurately.

Hello everyone. My Mac is running very slowly when I am using the internet, and especially when on Facebook. The little rainbow globe spins around for ages before changing pages etc. I have done several virus checks etc, but cannot find anything wrong. Sorry, but I am not tech savvy, so have difficulty with these issues.
Thanks for your reply. Well, I am not sure about the OS X version, I just gave that info from the Install DVD. I have the machine on automatic updates so I guess I am using a newer version. I know it is iMac Snow Leopard and I bought it in 2009. It is the 21.5 inch model. That is all I can tell you. I have 499GB and have used only 32GB, so it isn't a space problem.

Your profile was way out of date so the updater I gave you will not be suitable. This thread does prove the need to keep up to date.
The 4GB is sufficient for your apparent needs though it may be helpful to apply the updater below for the newly advised OS. It may take some time; it is a biggie!
Mac OS X 10.6.8 Update Combo v1.1 Then check things out.
If that doesn't help check out the number of operations that are running in the background. If you have the iStat Pro app located in your dashboard, that will help. It's an excellent app - and free. See if they're all necessary.
Apple - Downloads - Dashboard Widgets - iStat Pro
Almost certainly others will chip in soon but hopefully I've set you on your way. -
My Mac Mini runs very slowly. I upgraded memory but it didn't help. Wi-Fi is very fast with other computers in sae location so I don't think that is the issue. Ideas?
Hi, is it just Wifi that is slow?
If so try this...
Make a New Location, Using network locations in Mac OS X ...
http://support.apple.com/kb/HT2712
10.5, 10.6, 10.7 & 10.8…
System Preferences>Network, top of window>Locations>Edit Locations, little plus icon, give it a name.
10.5.x/10.6.x/10.7.x/10.8.x instructions...
System Preferences>Network, click on the little gear at the bottom next to the + & - icons, (unlock lock first if locked), choose Set Service Order.
The interface that connects to the Internet should be dragged to the top of the list.
10.4 instructions...
Is that Interface dragged to the top of Network>Show:>Network Port Configurations.
If using Wifi/Airport...
Instead of joining your Network from the list, click the WiFi icon at the top, and click join other network. Fill in everything as needed.
For 10.5/10.6/10.7/10.8, System Preferences>Network, unlock the lock if need be, highlight the Interface you use to connect to Internet, click on the advanced button, click on the DNS tab, click on the little plus icon, then add these numbers...
208.67.222.222
208.67.220.220
(There may be better or faster DNS numbers in your area, but these should be a good test).

Hi Apple Community,
My mac has been running very slowly, and there has been several other problems as well. I have a early 2009 iMac, running OS X 10.9.5. First of all, I have recently moved all of my photos and music to an external hard drive to clear up the internal hard drive, and Time Machine is also backing up to an external hard drive, and the internal hard drive is now about 60% free. I thought that would be able to get my Mac to run quicker, but it is still has slow as it was before. I have read recent community posts on what to do about this, one suggested downloading Etresoft to get a report on the condition of my mac. I ran Etresoft (I honestly don't know what to make of anything in the report), and the report is here:
Problem description:
Mac runs very slowly, applications will take longer than usual to open. Internal hard drive is about 60% full, and 3 external hard drives are used to hold photos, music, and backups.

So if someone could please explain what this means, or suggest some other ways to find out what is wrong with my Mac, it would be extremely helpful.
Thanks
MorganYou need to uninstall all Norton Antivirus softwarwe/ utilities.
https://support.norton.com/sp/en/us/home/current/solutions/kb20080427024142EN_En dUserProfile_en_us
Also, uninstall all Seagate hard drive software.
In addition, you need to install more RAM into your iMac.
Your year and model IMac can take a max. total of 8 GBs of RAM.
I strongly recommend that you purchase and install the maximum amount of RAM.
Correct, compatible and reliable Mac RAM can ONLY be purchased from online RAM sources Crucial memory or OWC (macsales.com). -
Hi All,
I am using a Mac Mini at work and it is running very slowly at the moment. General tasks are ok, but anythng video related (youtube is a nightmare to use) is super slow, and when closing it down it often takes several attepts as it seems to hang.
I am running MAC OS X 10.6.8 have 4GB of RAM
I have plenty of space on the HDD
Any thoughts would be appreciated.
ThanksMac troubleshooting: What to do when your computer is too slow | Macworld

HT6065 After upgrading to Mavericks , I now find my Mac mini runs very slowly.
Now that I've upgraded to Mavericks why does my Mac mini feel like a PC?
Speed was never an issue I have stock standard 2011 model....
Processor 2.3 GHz Intel Core i5
Memory 16 GB 1333 MHz DDR3
Graphics Intel HD Graphics 3000 512 MB
500Gb Hdd SATA (175Gb free)
1x USB3 external hub w/- 4 Seagate external self powered hard drives
(3x 2Tb/ 1x 1Tb)
I regularly remove files that I no longer require, I use Clean my Mac and remove the garbage regularly too.
I have checked for any open programs with activity monitor and the results are.....there hasn't been any.
As mentioned before upgrading I was using OSX Mountain Lion with no problems at all.
My son said" Don't upgrade until all the bugs are ironed out"
Well.....Younger generation knows best
and of course I use Time machine for back ups.
So I am very tempted to downgrade after the new year...
Any speed resolutions would be handy
Thanks in advanceIf you don't already have a current backup, back up all data before doing anything else. This procedure is a diagnostictest. It changes nothing, for better or worse, and therefore will not, in itself, solve your problem. The backup is necessary in case your startup drive is failing.
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 procedure will help identify which such modifications you've installed, as well as some other aspects of the configuration that may be related to the problem. Don’t be alarmed by the seeming complexity of these instructions — they’re easy to carry out.
If possible, these steps should be taken while booted in “normal” mode, not in safe mode. If you’re now running in safe mode, reboot as usual before continuing. If you can only boot in safe mode, you can still use this procedure, but not all of it will work. Be sure to mention that in your reply, if you haven't already done so.
Below are instructions to enter UNIX shell commands. The commands are safe and do nothing but produce human-readable output, but they must be entered exactly as given in order to work. If you question the safety of the procedure suggested here — which you should — search this site for other discussions in which it’s been followed without any report of ill effects. I am not asking you to trust me. If you can't satisfy yourself that these instructions are safe, don't follow them.
The commands will line-wrap or scroll in your browser, but each one is really just 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, and you can then copy it.
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. Step 1 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 (“$”) or a percent sign (“%”). If you get the percent sign, enter “sh” and press return. You should then get a new line ending in a dollar sign.
Step 1
Triple-click anywhere in the line of text below on this page to select it:
PB=/usr/libexec/PlistBuddy; PR () { [[ "$o" ]] && printf '\n%s:\n%s\n' "$1" "$o"; }; PF () { o=$($PB -c Print "$2" | awk -F'= ' \/$3'/{print $2}'); PR "$1"; }; { o=$(( $(vm_stat | awk '/Pageo/{print $2}' | tr -d .)/256 )); [[ $o -gt 1024 ]] && printf "\nPageouts: %s MiB\n" $o; o=$(kextstat -kl | grep -v com\\.apple | cut -c53- | cut -d\< -f1); PR "Loaded extrinsic kernel extensions"; o=$(launchctl list | sed 1d | awk '!/0x|com\.apple|org\.(x|openbsd)|\.[0-9]+$/{print $3}'); PR "Loaded extrinsic user agents"; o=$(launchctl getenv DYLD_INSERT_LIBRARIES); PR "Inserted libraries"; o=$(crontab -l); PR "User cron tasks"; o=$(cat /e*/lau*); PR "Global launchd configuration"; o=$(cat ~/.lau*); PR "Per-user launchd configuration"; PF "Global login items" /L*/P*/loginw* Path; PF "Per-user login items" L*/P*/*loginit* Name; PF "Safari extensions" L*/Saf*/*/E*.plist Bundle | sed 's/\..*$//;s/-[1-9]$//'; o=$(find ~ $TMPDIR.. \( -flags +sappnd,schg,uappnd,uchg -o ! -user $UID -o ! -perm -600 \) | wc -l); [[ $o -eq 0 ]] || printf "\nRestricted user files: %s\n" $o; cd; o=$(find -L /S*/L*/E* {,/}L*/{A*d,Compon,Ex,In,Keyb,Mail/Bu,P*P,Qu,Scripti,Servi,Spo}* -type d -name Contents -prune | while read d; do ID=$($PB -c 'Print :CFBundleIdentifier' "$d/Info.plist"); ID=${ID:-No bundle ID}; egrep -qv "^com\.apple\.[^x]|Accusys|ArcMSR|ATTO|HDPro|HighPoint|driver\.stex|hp-fax|JMicron|microsoft\.MDI|print|SoftRAID" <<< $ID && printf '%s (%s)\n' "${d%/Contents}" "$ID"; done); PR "Extrinsic loadable bundles"; o=$(find /u*/{,*/}lib -type f -exec sh -c 'file -b "$1" | grep -qw shared && ! codesign -v "$1"' {} {} \; -print); PR "Unsigned shared libraries"; for d in {,/}L*/{La,Priv,Sta}* L*/Fonts; do o=$(ls -A "$d"); PR "$d"; done; } 2> /dev/null | pbcopy; echo $'\nStep 1 done'
Copy the selected text to the Clipboard by pressing the key combination command-C. Then click anywhere in the Terminal window and paste (command-V). I've tested these instructions only with the Safari web browser. If you use another browser, you may have to press the return key after pasting.
The command may take up to a few minutes to run, depending on how many files you have and the speed of the computer. Wait for the line "Step 1 done" to appear below what you entered. The output of the command will be automatically copied to the Clipboard. If the command produced no output, the Clipboard will be empty. Paste into a reply to this message. No typing is involved in this step.
Step 2
Remember that you must be logged in as an administrator for this step. Do as in Step 1 with this line:
PR () { [[ "$o" ]] && printf '\n%s:\n%s\n' "$1" "$o"; }; { o=$(sudo launchctl list | sed 1d | awk '!/0x|com\.(apple|openssh|vix\.cron)|org\.(amav|apac|calendarse|cups|dove|isc|ntp|post[fg]|x)/{print $3}'); PR "Loaded extrinsic daemons"; o=$(sudo defaults read com.apple.loginwindow LoginHook); PR "Login hook"; o=$(sudo crontab -l); PR "Root cron tasks"; o=$(syslog -k Sender kernel -k Message CReq 'GPU |hfs: Ru|I/O e|find tok|n Cause: -|NVDA\(|pagin|timed? ?o' | tail | awk '/:/{$4=""; print}'); PR "Log check"; } 2> /dev/null | pbcopy; echo $'\nStep 2 done'
This time you'll be prompted for your login password, which you do have to type. Nothing will 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.
You can then quit Terminal.
To prevent confusion, I'll repeat: When you type your password in the Terminal window, you won't see what you're typing.
Note: If you don’t have a login password, set one before taking Step 2. If that’s not possible, skip the step.
Important: If any personal information, such as your name or email address, appears in the output of these commands, anonymize it before posting. Usually that won't be necessary.
Remember, Steps 1 and 2 are all copy-and-paste — type only your password. Also remember to post the output. -

帖子经 karoc编辑过Start by working out what model you have.
Apple Menu > About this Mac > More info button. Look for the 'Model Identifier'. Also check the OS version that appears in the first dialog.
iMacs from around 2003 cannot run 10.6.8, so something is not correct.
Many things could be the reason for slowness - you need to indicate what is wrong, when it happens what apps are being used.
If you have system disks backup this Mac & run Disk Utility from the install DVD/CD to see if the disk is OK, repair the boot disk. It also helps to remove ALL non Apple USB, Firewire & other devices to see if any attached devices cause the slowness.
It could also be that hardware is failing, so a backup is essential. The original grey install disks will have Apple hardware test which may indicate a fault (or may just report an erroneous message). Record any error numbers & re run the tests several times (issues can depend on temperature). The instructions should be printed on the install disk (normally hold D @ startup with it inserted).
If you have spare external HD's it may be simplest to install a clean version of OS X to see if that boots & is stable. Firewire may be the fastest connection type on older iMacs.
I assume this Mac has been running this OS for a while now? Have you got a full backup of it? How much is installed on it? Are you fastidious about updating software & removing things you don't use?
If any bits are unclear ask & we may be able to dig out links that explain parts of it, but it's important to know the model & OS version accurately. -
Internet on Mac suddenly running very slowly
I've had my imac for a few months now and evrything seemed to be fine. Now my internet is going really slow. All my other devices on wifi run fine and anything non internet related on my mac runs fine. Any ideas on what is happening?

Please Help!!

Is there a way to fix this?
Yes and no......99.9% NO however.
When a HD dies its like asking about "cleaning a used paper towell"..........no.
$70 for a nice 1TB HD replacement, very easy to do , see videos posted above for you on replacing your HD.
In the future ALWAYS have a HD clone!
HD clones
Advantages:
1. HD clones are the best, quickest way to get back to 100% full operation in mere seconds.
2. Once a HD clone is created, the creation software (Carbon Copy Cloner or SuperDuper) is no longer needed whatsoever, and unlike TM, which requires complex software for its operational transference of data, a HD clone is its own bootable entity.
3. HD clones are unconnected and isolated from recent corruption.
4. HD clones allow a “portable copy” of your computer that you can likewise connect to another same Mac and have all your APPS and data at hand, which is extremely useful.
5. Rather than, as many users do, thinking of a HD clone as a “complimentary backup” to the use of TM, a HD clone is superior to TM both in ease of returning to 100% quickly, and its autonomous nature; while each has its place, TM can and does fill the gap in, say, a 2 week old clone. As an analogy, the HD clone itself is the brick wall of protection, whereas TM can be thought of as the mortar, which will fill any cracks in data on a week, 2-week, or 1-month old HD clone.
6. Best-idealized 2nd platform redundancy for data protection, and 1st level for system restore of your computers internal HD. (Time machine being 2nd level for system restore of the computer’s internal HD). -

You could post in the notebook and Mac OS forums, look under the hood and diagnose the patient. Figure what you did or are doing. You can also relolad the OS and files from backup.

My Macbook Pro is running very slowly, what can I do?
Things You Can Do To Resolve Slow Downs
If your computer seems to be running slower here are some things you can do:
Start with a visit to: OS X Maintenance - MacAttorney.
Boot into Safe Mode then repair your hard drive and permissions:
Repair the Hard Drive and Permissions Pre-Lion
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 Utilities menu. 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.
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.
Repair the Hard Drive - Lion
Boot from your Lion Recovery HD. When the recovery menu appears select Disk Utility. 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, then click on the Repair Permissions button. Wait until the operation completes, then quit DU and return to the main menu. Select Restart from the Apple menu.
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.
Restart your computer normally and see if this has helped any. Next do some maintenance:
Suggestions for OS X Maintenance
For situations Disk Utility cannot handle the best third-party utility is Disk Warrior; DW only fixes problems with the disk directory, but most disk problems are caused by directory corruption; Disk Warrior 4.x is now Intel Mac compatible.
OS X performs certain maintenance functions that are scheduled to occur on a daily, weekly, or monthly period. The maintenance scripts run in the early AM only if the computer is turned on 24/7 (no sleep.) If this isn't the case, then an excellent solution is to download and install a shareware utility such as Macaroni, JAW PseudoAnacron, or Anacron that will automate the maintenance activity regardless of whether the computer is turned off or asleep. Dependence upon third-party utilities to run the periodic maintenance scripts was significantly reduced since Tiger. These utilities have limited or no functionality with Snow Leopard or Lion and should not be installed.
OS X automatically defragments files less than 20 MBs in size, so unless you have a disk full of very large files there's little need for defragmenting the hard drive. As for virus protection there are few if any such animals affecting OS X. You can protect the computer easily using the freeware Open Source virus protection software ClamXAV. Personally I would avoid most commercial anti-virus software because of their potential for causing problems. For more about malware see Macintosh Virus Guide.
I would also recommend downloading a utility such as TinkerTool System, OnyX 2.4.3, or Cocktail 5.1.1 that you can use for periodic maintenance such as removing old log files and archives, clearing caches, etc.
For emergency repairs install the freeware utility Applejack. If you cannot start up in OS X, you may be able to start in single-user mode from which you can run Applejack to do a whole set of repair and maintenance routines from the command line. Note that AppleJack 1.5 is required for Leopard. AppleJack 1.6 is compatible with Snow Leopard. There is no confirmation that this version also works with Lion.
When you install any new system software or updates be sure to repair the hard drive and permissions beforehand.
Get an external Firewire drive at least equal in size to the internal hard drive and make (and maintain) a bootable clone/backup. You can make a bootable clone using the Restore option of Disk Utility. You can also make and maintain clones with good backup software. My personal recommendations are (order is not significant):
1. Carbon Copy Cloner
2. Data Backup
3. Deja Vu
4. SuperDuper!
5. SyncTwoFolders
6. Synk Pro
7. Synk Standard
8. Tri-Backup
Visit The XLab FAQs and read the FAQs on maintenance, optimization, virus protection, and backup and restore.
Additional suggestions will be found in Mac maintenance Quick Assist.
Referenced software can be found at CNet Downloads or MacUpdate.
Additional Hints
Be sure you have an adequate amount of RAM installed for the number of applications you run concurrently. Be sure you leave a minimum of 10% of the hard drive's capacity as free space.
Add more RAM. If your computer has less than 2 GBs of RAM and you are using OS X Leopard or later, then you can do with more RAM. Snow Leopard and Lion work much better with 4 GBs of RAM than their system minimums. The more concurrent applications you tend to use the more RAM you should have.
Always maintain at least 15 GBs or 10% of your hard drive's capacity as free space, whichever is greater. OS X is frequently accessing your hard drive, so providing adequate free space will keep things from slowing down.
Check for applications that may be hogging the CPU:
Open Activity Monitor in the Utilities folder. Select All Processes from the Processes dropdown menu. Click twice on the CPU% column header to display in descending order. If you find a process using a large amount of CPU time, then select the process and click on the Quit icon in the toolbar. Click on the Force Quit button to kill the process. See if that helps. Be sure to note the name of the runaway process so you can track down the cause of the problem.
Often this problem occurs because of a corrupted cache or preferences file or an attempt to write to a corrupted log file.

Installing bootdrive in Pavilion AiO
Hi, I have Pavilion Model 22-h020ex that came with a 1TB HD (Model WDC WD10EZEX-60M2NA0) and its kind of slow when editing very large excel sheets or opening 10 applications at once. I plan to install a fast boot drive (SSD / mSATA / M.2). My quest
