My macbook pro always runs 30°c cooler immediately after a system update

For the two days following any system update my macbook runs about 30°c cooler than normal (45-50°c), then after a couple of days it returns to its usual operating temperature of 75-80°c. This has happened probably since leopard and happens exactly the same with every system update.
What is going on?
Does this happen to anyone else?

MacBook Pro hanging with blue screen and spinner after installing Software Update

Hi I was wondering if someone could help me with this current issue. Just a few hours ago I finished reinstalling Mac OS X Snow Leopard in my MacBook Pro. I performed a clean installation as part of a yearly spring cleaning that I do on all my systems to keep them optimized. So there was I downloading some software updates which included the combo update of OSX 10.6.8 and others. The updates finished downloading and the system logged out to install the updates, when the updates finished installing my MacBook proceeded by logging out into a blue screen and show a gray spinner similar to the one seen when you start your Mac. Here's the problem after 2 hours the system is showing the spinner and the blue screen, I think that my computer has just hanged in the reboot process.
I was wondering what should I do? Do a force restart? Or leave it overnight?
Also, where can I find any information on what error is causing this issue?
I appreciate your responses and help.
By the way, I installed Mac OS X from a USB stick that has the original image of the disk installer that came bundled with my computer.

Force a shutdown. Do not restart yet, but first do the following:
Repair the Hard Drive
Boot from your Snow Leopard 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, 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.
Next, boot into Safe Mode then restart normally.
Hi Kappy,
Checked the hard drive after forcing a shutdown and booting from my Snow Leopard Installer USB Key and the status of the HDD says "Verified". I ran the repair and the volume was repaired successfully. Clicked on "Verify Disk" and it says "Macintosh HD appears to be OK". So I ran a second repair and again no errors were reported.
As suggested I booted back again in Safe Mode and restarted normally. All software appears to have been installed successfully. But I don't understand why my computer hanged and showed the spinner after installing the updates in the blue screen that appears just before rebooting. I am aware that the system shows that spinner after a OS update but the longest it lasts is 30 seconds at the most in my previous cases.

Macbook Pro Retina display says "No batteries available" after legitimate system software update

Issue Description
On July 26, 2012 I placed an order with Apple store for the 15-inch MacBook Pro with Retina display with the following configuration (Order # W269108641 Serial# C02J52S9DKQ5):
Processor 2.6GHz Quad-core Intel Core i7, Memory 16GB 1600MHz DDR3L SDRAM, Flash Storage 512GB Flash Storage
It was delivered August 8, 2012. It cost me $3,265.16
I have since equipped it with accessories like a wireless apple keyboard ($69), wireless mouse ($69), USB super drive ($79), VGA display adapter ($29), Ethernet Adapter ($29) and the excellent sleeve/pouch from Pack & Smooch GmbH (GBP60))
It's so heavily configured because it’s my main workstation. I additionally bought and installed Parallels 8 so I can run Windows 8 in a Virtual Machine because I have a few things on Windows that I need to be productive. This setup has been a dream machine until a little over a week ago.
In the one year since I bought it, I have had only 2 issues;
• A case of display flickering that resulted after a system software update on August 28, 2013
(Case ID 498560320 - not much help came from Apple Support but fortunately the problem went away a week later after another system software update)
• A case of battery failure that resulted after a system software update on October 11, 2013
(Case ID 516534003 - I have gone through all recommendations from Apple support as I will detail below)
Symptoms after system software update
• Battery Icon on status bar disabled with a message "No batteries available"
• Battery not charging
• LED on the Magsafe power adapter no longer show
• Keyboard backlights no longer show
• Notebook fan loud/noisy and permanently at high speed
• Date and time reset to a date in the past at each restart
• Notebook starts up the moment the Magsafe adapter is connected without waiting for power button to be pressed
• An update for "MacBook Pro Retina Display SMC Update 1.2" keeps appearing in Software Update
Recommendations from Apple Support
• Perform SMC Reset (http://support.apple.com/kb/HT3964)
(Done - no change in status)
• Run Disk Utility
(Done - no errors found)
• Run Apple Hardware test (http://support.apple.com/kb/HT1509)
(Done - no errors found, no change in status)
• Visit Apple Store
(Done - they confirmed no issue with Magsafe adapter. For a fee they are happy to change the battery if confirmed faulty and re-install the OS if the battery is not the issue but am uncertain that the OS re-install will resolve the issue because I have read online about a similar case where a re-install did not resolve the issue)
• Check System Report/Hardware/Power
(Done - Health Information/Cycle count:0, Battery installed: No)
• Perform NVRAM Reset (http://support.apple.com/kb/HT1379?viewlocale=en_US)
(Done - no change in status)
Comments and additional Observations
Please note the following;
• All of the symptoms above appeared after a system software update on October 11, 2013
• This update first appeared on October 10, 2013 but I was too busy to apply it especially because it required a system restart
• The battery was fully charged when I decided to apply the update on October 11 morning after I got to work
• Normally on full charge, the battery will typically deliver 3 - 4 hours depending on usage and up to 6 hours when idle
• The said update was not interrupted or anything of the sort
• On the day the symptoms were first observed when I first logged the case with apple, the system ran on battery while it performed the Apple Hardware Test while I was driving to the Apple support store on my way home even though the status bar was indicating "No battery available"
I make the following deductions solely based on my observations
• An apple authorized system software update broke the system
• The nature of the failure is communication related - the battery charging circuit and related systems are not getting the necessary instructions to function as they should (It's a known fact that rechargeable batteries do NOT die instantaneously, the total hours they run on full charge will gradually reduce over time as they degrade on use)
• It’s possible the update is not being applied correctly because the item “MacBook Pro Retina Display SMC Update 1.2” is still in Software update after subsequent attempts to apply it
• The high fan speed is nothing to do with high temperature or high processor load, according to the Activity Monitor utility the highest CPU utilization 1.9 – 4.7% is by kernel_task (PID 0) followed by activitymonitord at 1.8 – 2.2% (PID 481)
• The symptoms match what an SMC reset should resolve according to Apple documentation
• This is a known problem within Apple based on the documentation provided and the numerous similar cases reported online
Summary;
The system is running OS X 10.8.5
I have provided this detailed documentation in the hope that someone who understands this system can say exactly what is going on. It's meant to be a dream machine but now you can hear the fan from across a large room, the battery doesn't charge and is in fact not recognized so I lose data if the Magsafe adapter gets unplugged, and I have to reset the system date each time I restart the notebook.
I've used this notebook with utmost care for a little more than a year, this investment of over $3,500 could have bought 3 high end notebooks from DELL or HP but I chose Apple.
I have suffered untold loss in productivity in the last 10 days since this issue occurred, I respectfully request Apple to fix my notebook.

Canon printer WORKS in MacBook Pro but NOT in Chrome/ iPhone 6 after iOS 8 update

Canon printer WORKS in MacBook Pro but now NOT in Chrome/ iPhone 6 after iOS 8 update. The printer worked previously with NO PROBLEMS. The printer is online & connected to the WiFi, not issues.
WHY???!!!???

You probably would get better answers in either the iPhone or iOS forums. This is for Macbooks. I've asked the hosts to move it.

My mind 2014 macbook pro keeps freezing and is very slow after the yosemite update

HI my macbook 2014 model keeps freezing and it is very slow after i had updated it to yosemite

Why don't you try these: ( might or might not help, but it's worth a try )
See what you have loading on your login items.
Open up activity momitor, under All Procesess, see what's using most of your CPU resources (%).
Hightlight the one using the highest % on the CPU then click on quit process and see if that works.
Once you're done with that, go to Disk Utility and do a verify disk. After that, do a verify disk permission and repair if needed.
See if that helps you.

Macbook Pro won't start up passed installer after failed lion update.

After installing what seems now to be a phony Lion update, my mac won't fully start up. Whenever i turn it on it will bring me to the installer and I can't seem to figure out how to start up on snow leopard again. I believe all my files are still intact. Whenever i turn it on it brings me to language options then utilities where i can choose to start from back up, disc utilites, reinstall lion, or use safari. Can anyone help me with this?

Since you appear to be running Lion do the following:
Reinstalling Lion Without Erasing the Drive
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 the Hard Drive and Permissions: Upon startup select Disk Utility from the main menu. Repair the Hard Drive and Permissions as follows.
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 click on the Repair Permissions button. Wait until the operation completes, then quit DU and return to the main menu.
Reinstall Lion: Select Reinstall Lion and click on the Continue button.
Note: You will need an active Internet connection. I suggest using Ethernet if possible because it is three times faster than wireless.

My MacBook Pro is running on an older version of Mac OS X but will not allow me to upgrade to a newer version

My MacBook Pro is running on a 10.5.8 operating system but has not allowed me to upgrade. It has been fine for the past few years but is now getting to the point where programs are not functioning properly. What operating system should I be trying to upgrade to and what should I do in order for the upgrade to work? I have tried upgrading to Mac OS X Snow Leopard but it says that I need 10.6 in order to upgrade to Snow Leopard. The only upgrade that has begun to work has been a 10.5.6 which is a less updated version of the operating system that I'm already using. Will downloading 10.5.6 allow me to upgrade to a better version? Any help is appreciated! Thanks!

Choose About this Mac from the Apple menu and check the processor.
If it's a Core Duo Mac, click here, install the DVD, and run Software Update.
If it's a Core 2 Duo or better Mac, upgrade it as if it was a Core Duo Mac, and if desired, open the Mac App Store, and try downloading 10.9. If you get told it's incompatible, go to the online Apple Store and order a download code for Lion 10.7.
Mac OS X 10.7 and newer don't support PowerPC software such as Microsoft Office 2004. If you upgrade the OS, back up the computer first.

Why does safari not update to 5.1 on macbook pro when running lion 10.7.1

my macmini is running lion server and safari 5.1. my iMac is running lion and safari 5.1. my macbook pro is running lion and safari 4.0.4 and update is stating that there are no updates available.
how does one force an update to safari 5.1 for lion in this situation?

my macbook pro is running lion and safari 4.0.4 and update is stating that there are no updates available.
Did you move or copy the Safari application? It should be in the Applications folder at the top level of your startup volume.
There is no downloadable installer for the Lion version of Safari.

Back up your Mac if you have not done so already. To learn how to use Time Machine read Mac Basics: Time Machine backs up your Mac - Apple Support.
Uninstall MacKeeper:
Follow these instructions to uninstall MacKeeper. They have been tested with the most recent version of MacKeeper. Earlier versions than the one released in 2012 required more extensive work to uninstall all its components.
If you actually used MacKeeper to alter your system, e.g. "remove excess binaries" or such, you will need to reinstall OS X as well as all your additional software. Uninstalling MacKeeper is insufficient to reverse the corruption it is capable of - once again, that is if you used it.
If you merely installed MacKeeper but did not use it to perform any particular action, the following instructions will suffice.
If you used MacKeeper to encrypt any files or folders, use MacKeeper to un-encrypt them first.
Quit the MacKeeper app if it is running.
Open your Applications folder: Using the Finder's Go menu, select Applications.
Drag the MacKeeper icon from your Applications folder (not the Dock) to the Trash.
You will be asked to authenticate (twice):
You do not need to provide a reason for uninstalling it:
Just click the Uninstall MacKeeper button. You will be asked to authenticate again.
After it uninstalls you may empty the Trash and restart your Mac. All that will remain is an inert log file that does nothing but occupy space on your hard disk.

My MacBook Pro fan runs while sleeping

My MacBook Pro fan runs constantly, even while sleeping.
The problem started about 2-3 months ago, but was pretty rare. When I noticed the problem, I would restart the computer and it would stop for 1-2 weeks. More recently it has become more constant, and now it always has the fan running when it's sleeping.
Any ideas on what I should do? Thanks!

Mine too. If you're worried you might like to try a laptop cooler like one of these:

Not sure how well they'd work on a Macbook as there aren't any vents on the underside but it couldn't hurt and they're quite cheep.

Macbook Pro is running slow after mavericks upgrade

Hello everyone,
I recently downloaded the last update of Mavericks on my Macbook pro (13 inch, mid 2012).
Since the upgrade, my mac has been incredibly slow... I have tried different things including: completely re downloading and installing mavericks, running the apple hardware test (both short and long tests), I have tried to fix it through resetting the macbook to factory settings. None of my attempts were successful.
The Hardware:
Mid 2012 Macbook Pro.
Running OS X 10.9.4 Mavericks
2,5 GHz intel Core I5
4GB 1600 MHz DDR3
The Problem:
I updated Mavericks to its last version (10.9.4) and all of a sudden my macbook became super slow. It had no problem before, even under Mavericks, so my guess was it is a problem linked to this last version...
What I've Done Thus Far:
- Apple Hardware Tests (both long and short): All passed
- Reinstalled Mavericks
- Restoring to factory settings
Any suggestions on what do to?
Thank you!
Nathan.

Macbook Pro 2011 - running slow after installing Yosemite

Can anyone help me - my late 2011 Macbook Pro is running very slow since installing Yosemite. Also my Microsoft Office for Excel is not allowing me to type into cells - I can copy and paste but not add new text.
I have run the Etre diagnostic app (as suggested on another thread) and these are the results I get. Can anyone help - or do I have to uninstall Yosemite and how would I do this?
Problem description:

My Macbook Pro started running really slow

This week my Macbook Pro started running super slow, taking ages to open programs and giving me the color wheel alllll the time. I've never had problems like this before! I'm not running many applications or doing anything unusual but it's just running extra slow. Once or twice it has also totally gone to sleep while I was in the middle of using it, and I had to wake it back up. It has also been getting really hot and the battery life seems worse...! This is all new, I'm using my computer just as I always have but it suddenly has issues.
The only thing it has been doing for a while is sometimes the screen will go blue - this either corrects itself within a few seconds or if I close my Macbook and then reopen it, the screen is back to normal. This is very rare though and I don't know if it's related to the slowness problem.
What can I do to fix this??

The startup drive is failing, or there is some other internal hardware fault. The "etrecheck" output is irrelevant.
Back up all data on the drive immediately if you don't already have a current backup. There are ways to back up a computer that isn't fully functional — ask if you need guidance.
Make a "Genius" appointment at an Apple Store, or go to another authorized service provider.
If privacy is a concern, erase the data partition(s) with the option to write zeros* (do this only if you have at least two complete, independent backups, and you know how to restore to an empty drive from any of them.) Don’t erase the recovery partition, if present.
Keeping your confidential data secure during hardware repair
Apple also recommends that you deauthorize a device in the iTunes Store before having it serviced.
*An SSD doesn't need to be zeroed.

Kappy's Personal Suggestions About OS X Maintenance
For disk repairs use Disk Utility. For situations DU 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. Drive Genius provides additional tools not found in Disk Warrior for defragmentation of older drives, disk repair, disk scans, formatting, partitioning, disk copy, and benchmarking.
Four outstanding sources of information on Mac maintenance are:
1. OS X Maintenance - MacAttorney.
2. Mac maintenance Quick Assist
3. Maintaining Mac OS X
4. Mac Maintenance Guide
Periodic Maintenance
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.) See Mac OS X- About background maintenance tasks. If you are running Leopard or later these tasks are run automatically, so there is no need to use any third-party software to force running these tasks.
If you are using a pre-Leopard version of OS X, 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 after Tiger. (These utilities have limited or no functionality with Snow Leopard, Lion, or Mountain Lion and should not be installed.)
Defragmentation
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 except when trying to install Boot Camp on a fragmented drive. But you don't need to buy third-party software. All you need is a spare external hard drive and Carbon Copy Cloner.
Cheap and Easy Defragmentation
You will have to backup your OS X partition to an external drive, boot from the external drive, use Disk Utility to repartition and reformat your hard drive back to a single volume, then restore your backup to the internal hard drive. You will use Carbon Copy Cloner to create the backup and to restore it.
1. Get an empty external hard drive and clone your internal drive to the
       external one.
2. Boot from the external hard drive.
3. Erase the internal hard drive.
4. Restore the external clone to the internal hard drive.
Clone the internal drive to the external drive
1. Open Carbon Copy Cloner.
2. Select the Source volume from the left side dropdown menu.
3. Select the Destination volume from the left side dropdown menu.
4. Be sure the Block Copy button is not depressed or is ghosted.
5. Click on the Clone button.
Destination means the external backup drive. Source means the internal startup drive.
Restart the computer and after the chime press and hold down the OPTION key until the boot manager appears. Select the icon for the external drive and click on the upward pointing arrow button.
After startup do the following:
Erase internal hard drive
1. Open Disk Utility in your Utilities folder.
2. After DU loads select your internal hard drive (this is the entry with the
       mfgr.'s ID and size) from the left side list. Note the SMART status of the
       drive in DU's status area. If it does not say "Verified" then the drive is
       failing or has failed and will need replacing. SMART info will not be
       reported on external drives. Otherwise, click on the Partition tab in the
       DU main window.
3. Under the Volume Scheme heading set the number of partitions from the
       drop down menu to one. Set the format type to Mac OS Extended
       (Journaled.) Click on the Options button, set the partition scheme to
       GUID then click on the OK button. Click on the Partition button and wait
       until the process has completed.
Restore the clone to the internal hard drive
1. Open Carbon Copy Cloner.
2. Select the Source volume from the left side dropdown menu.
3. Select the Destination volume from the left side dropdown menu.
4. Be sure the Block Copy button is not selected or is ghosted.
5. Click on the Clone button.
Destination means the internal hard drive. Source means the external startup drive.
Note that the Source and Destination drives are swapped for this last procedure.
Malware Protection
As for malware protection there are few if any such animals affecting OS X. Starting with Lion Apple has included built-in malware protection that is automatically updated as necessary.
Helpful Links Regarding Malware Protection:
1. Mac Malware Guide.
2. Detecting and avoiding malware and spyware
3. Macintosh Virus Guide
For general anti-virus protection I recommend only using ClamXav, but it is not necessary if you are keeping your computer's operating system software up to date. You should avoid any other third-party software advertised as providing anti-malware/virus protection. They are not required and could cause the performance of your computer to drop.
Cache Clearing
I recommend downloading a utility such as TinkerTool System, OnyX 2.4.3, Mountain Lion Cache Cleaner 7.0.9, Maintenance 1.6.8, or Cocktail 5.1.1 that you can use for periodic maintenance such as removing old log files and archives, clearing caches, etc. Corrupted cache files can cause slowness, kernel panics, and other issues. Although this is not a frequent nor a recurring problem, when it does happen there are tools such as those above to fix the problem.
If you are using Snow Leopard or earlier, then for emergency cleaning 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. (AppleJack works with Snow Leopard or earlier.)
Installing System Updates or Upgrades
When you install any new system software or updates be sure to repair the hard drive and permissions beforehand.
Backup and Restore
Having a backup and restore strategy is one of the most important things you can do to maintain your computer. 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. Deja Vu
3. SuperDuper!
4. Synk Pro
5. Tri-Backup
Visit The XLab FAQs and read the FAQs on maintenance and backup and restore.
Always have a current backup before performing any system updates or upgrades.
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 or 20 GBs, whichever is greater, as free space. Avoid installing utilities that rely on Haxies, SIMBL, or that alter the OS appearance, add features you will rarely if ever need, etc. The more extras you install the greater the probability of having problems. If you install software be sure you know how to uninstall it. Avoid installing multiple new software at the same time. Install one at a time and use it for a while to be sure it's compatible.

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.
Repair the Hard Drive - Lion/Mountain Lion/Mavericks
Boot to the Recovery HD:
Restart the computer and after the chime press and hold down the COMMAND and R keys until the Utilites 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 disk icon and click on the arrow button below.
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.
Restart your computer normally and see if this has helped any. Next do some 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.
Note: Alsoft ships DW on a bootable DVD that will startup Macs running Snow Leopard or earlier. It cannot start Macs that came with Lion or later pre-installed, however, DW will work on those models.

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 later 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.
Helpful Links Regarding Malware Protection
An excellent link to read is Tom Reed's Mac Malware Guide.
Also, visit The XLab FAQs and read Detecting and avoiding malware and spyware.
See these Apple articles:

          OS X Mountain Lion- Protect your Mac from malware
          About file quarantine in OS X
If you require anti-virus protection I recommend using VirusBarrier Express 1.1.6 or Dr.Web Light both from the App Store. They're both free, and since they're from the App Store, they won't destabilize the system. (Thank you to Thomas Reed for these recommendations.)
Troubleshooting Applications
I recommend downloading a utility such as TinkerTool System, OnyX, Mavericks Cache Cleaner, or Cocktail that you can use for removing old log files and archives, clearing caches, etc. Corrupted cache, log, or temporary files can cause application or OS X crashes as well as kernel panics.
If you have Snow Leopard or Leopard, then for similar 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. Applejack does not work with Lion and later.
Basic Backup
For some people Time Machine will be more than adequate. Time Machine is part of OS X. There are two components:
1. A Time Machine preferences panel as part of System Preferences;
2. A Time Machine application located in the Applications folder. It is
    used to manage backups and to restore backups. Time Machine
    requires a backup drive that is at least twice the capacity of the
    drive being backed up.
Alternatively, get an external 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. Get Backup
3. Deja Vu
4. SuperDuper!
5. Synk Pro
6. Tri-Backup
Visit The XLab FAQs and read the FAQ on backup and restore. Also read How to Back Up and Restore Your Files. For help with using Time Machine visit Pondini's Time Machine FAQ for help with all things Time Machine.

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:
Pre-Mavericks
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 (>=70,) 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.
Mavericks and later
Open Activity Monitor in the Utilities folder. Select All Processes from the View menu. Click on the CPU tab in the toolbar. Click twice on the CPU% column header to display in descending order. If you find a process using a large amount of CPU time (>=70,) 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.
