    There are many potential reasons that a Mac may be running slower than expected, but more information is required to begin troubleshooting, much more.


    Back up your documents and everything else important to you before proceeding. It is premature to conclude your hard disk is failing, but the symptoms you describe may presage an impending disk failure, and you should have backups anyway.


    To help determine the possible causes of this behaviour read the following. None of what follows is intended to fix anything, but it will provide the additional information required to advance troubleshooting:

    Boot OS X Recovery by holding and r (two fingers) while you start your Mac. At the Mac OS X Utilities screen, select Disk Utility. Select your startup volume (usually named "Macintosh HD") and click the Repair Disk button. Describe any errors it reports in red.


    When it finishes restart your Mac and test again for operation. If it's still not behaving as you expect it should, please post the results of EtreCheck in accordance with the following instructions:

    Apple Support Communities contributor etresoft wrote a very useful app to quickly gather certain system information that may help point to a cause of this problem. Go to his website, download and run EtreCheck:




    Etrecheck will be in your Downloads folder. Open it from there. You may see the following dialog box:




    Click Open - etresoft contributes to this forum frequently and can be considered a trustworthy developer.


    It will take a moment to run as it collects its data.


    Copy and paste its output in a reply.


    Do not be concerned about anything that says "Problem" or “failed” or anything else that may appear in red.


    EtreCheck was designed to remove any personal information (such as your computer's name and serial numbers) but if you see anything that looks like an email address or any other personal information that should not be divulged to others, please delete or obscure that information when you post the reply.


    When you are finished with EtreCheck, quit the program. It occupies very little space, and you can keep it or drag it to the Trash as you wish.

    After completing the above please determine if the problems also occur in "Safe Mode":


    • Safe Mode or "Safe Boot" is a troubleshooting mode that bypasses all third party system extensions and loads only required system components. Read about it: Starting up in Safe Mode
    • You must disable FileVault before you can start your Mac in Safe Mode.
    • Starting your Mac in Safe Mode will take longer than usual, graphics will not render smoothly, audio is disabled on some Macs, and some programs (iTunes for example) may not work at all.
    • Merely starting your Mac in Safe Mode is not intended to resolve the problem, it's to observe its performance without certain additional components.
    • To end Safe Mode restart your Mac normally. Shutdown will take longer as well.

    System performance problems for reasons that cannot be isolated to any other cause justify an SMC reset. Be sure to read the procedure carefully and follow all the steps exactly as written, even if they seem inapplicable or trivial.

    If you don't already have a current backup, back up all data before doing anything else. This procedure is a diagnostic  test. It changes nothing, for better or worse, and therefore will not, in itself, solve your problem. The backup is necessary on general principle, not because of anything suggested in this comment. There are ways to back up a computer that isn't fully functional. Ask if you need guidance.
    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. Here's a brief summary: In each of two steps, you copy a line of text from this web page into a window in another application. You wait about a minute. Then you paste some other text, which will have been copied automatically, back into a reply on this page. The sequence is copy; paste; paste again. That's all there is to it. Details follow.

    You may have started the computer in "safe" mode. Preferably, these steps should be taken while booted in “normal” mode. If the system is now running in safe mode and is bootable in normal mode, reboot as usual. If it only boots in safe mode, use that.

    Below are instructions to enter UNIX shell commands. They do nothing but produce human-readable output. However, you need to think carefully before running any program at the behest of a stranger on a public message board. 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. 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.
    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 () { [[ "$o" ]] && o=$(sed 's/^/   /' <<< "$o") && printf '\n%s:\n\n%s\n' "$1" "$o"; }; PC () { o=$(grep [^[:blank:]] "$2"); PR "$1"; }; PF () { o=$($PB -c Print "$2" | awk -F'= ' \/$3'/{print $2}'); PR "$1"; }; PN () { [[ $o -eq 0 ]] || printf "\n%s: %s\n" "$1" $o; }; { system_profiler SPSoftwareDataType | sed '8!d;s/^ *//'; o=$(system_profiler SPDiagnosticsDataType | sed '5,6!d'); fgrep -q P <<< "$o" && o=; PR "POST"; o=$(($(vm_stat | awk '/Pageo/{sub("\\.",""); print $2}')/256)); o=$((o>=1024?o:0));  PN "Pageouts (MiB)"; s=( $(sar -u 1 10 | sed '$!d') ); [[ ${s[4]} -lt 90 ]] && o=$( printf 'User %s%%\t\tSystem %s%%' ${s[1]} ${s[3]} ) || o=; PR "Total CPU usage"; [[ "$o" ]] && o=$(ps acrx -o comm,ruid,%cpu | sed '2!d'); PR "Max %CPU by process (name, UID, %)"; o=$(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"; PC "cron configuration" /e*/cron*; o=$(crontab -l | grep [^[:blank:]]); PR "User cron tasks"; PC "Global launchd configuration" /e*/lau*; PC "Per-user launchd configuration" ~/.lau*; PF "Global login items" /L*/P*/loginw* Path; PF "Per-user login items" L*/P*/*loginit* Name; PF "Safari extensions" L*/Saf*/*/E*.plist Bundle | sed 's/\..*$//;s/-[1-9]$//'; o=$(find ~ $TMPDIR.. \( -flags +sappnd,schg,uappnd,uchg -o ! -user $UID -o ! -perm -600 \) | wc -l); PN "Restricted user files"; 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=${ID:-No bundle ID}; egrep -qv "^com\.apple\.[^x]|Accusys|ArcMSR|ATTO|HDPro|HighPoint|driver\.stex|hp-fax|JMicron|microsoft\.MDI|print|SoftRAID" <<< $ID && printf '%s\n\t(%s)\n' "${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 "$1"' {} {} \; -print); PR "Unsigned shared libraries"; o=$(system_profiler SPFontsDataType | egrep "Valid: N|Duplicate: Y" | wc -l); PN "Font problems"; for d in {,/}L*/{La,Priv,Sta}*; 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 beautomatically copied to the Clipboard. All you have to do is paste into a reply to this message by pressing command-Vagain. Please don't copy anything from the Terminal window. 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 () { [[ "$o" ]] && o=$(sed 's/^/   /' <<< "$o") && printf '\n%s:\n\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=$(sudo crontab -l | grep [^[:blank:]]); PR "Root cron tasks"; o=$(syslog -k Sender kernel -k Message CReq 'GPU |hfs: Ru|I/O e|find tok|n Cause: -|NVDA\(|pagin|timed? ?o' | tail -n25 | awk '/:/{$4=""; print}'); PR "Log check"; } 2>&- | 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. Please note:

    ☞ Steps 1 and 2 are all copy-and-paste — type only your login password when prompted.
    When you type your password, you won't see what you're typing.
    ☞ If you don’t have a password, set one before taking Step 2. If that’s not possible, skip the step.
    ☞ Step 2 might not produce any output, in which case the Clipboard will be empty. Step 1 will always produce something.

    ☞ The commands don't change anything, and merely running them will do neither good nor harm.
    ☞ Remember to post the output of both steps (unless you had to skip Step 2.) It's already in the Clipboard after you complete each step. You don't have to copy it. Just paste into a reply    

    ☞ If any personal information, such as your name or email address, appears in the output of either command, anonymize it before posting. Usually that won't be necessary.

    Don't post what you see in the Terminal window. The output is copied automatically to the Clipboard.

    Don't paste the output of Step 1 into the Terminal window. Paste it into a reply.

  • madpat2012 Level 1 (10 points)


    Does a back up always have to be to an external hard drive. I dont have one

  • Csound1 Level 8 (46,935 points)

    Yes, and you must have one, unless your files do not matter to you.

  • Linc Davis Level 10 (192,559 points)

    If you don't have a backup, shut down the computer immediately and don't turn it on again until you have an external hard drive and are ready to back up.
