Kappy's Personal Suggestions About Mac 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.

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. To assure proper protection, update your system software when Apple releases new OS X updates for your computer.
Helpful Links Regarding Malware Protection:
1.Mac Malware Guide.
2. Detecting and avoiding malware and spyware
Mac Snow Leopard Download
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
Repair the hard drive and permissions beforehand.
Update your backups in case an update goes bad.
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. You can never have too many backups. Don't rely on just one. Make several using different backup utilities. 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 FAQs on maintenance and backup and restore.
Always have a current backup before performing any system updates or upgrades.
Final Suggestions
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.

Most if not all maintenance is for troubleshooting problems. If your computer is running OK, then there isn't really a thing you need to do except repair the hard drive and permissions before installing any new system updates.

In this article, we cover the best ways to clear your DNS cache on a Mac, including the different ways you can do that depending on the macOS you are running.
Your DNS cache acts like a memory that your Mac refers to when trying to figure out how to load a website.
Flushing the DNS isn’t a difficult task but the process changes with every new operating system. We’ll walk you through the steps needed to reset your DNS manually in the different versions of macOS and OS X, along with the easy solution of CleanMyMac X.
How to clear the DNS: The easy way
For those who want to get this done quickly, a much simpler alternative to clear the DNS cache on all versions of Mac is CleanMyMac.
CleanMyMac is a utility app designed to clean, optimize and maintain your Mac and flushing the DNS cache just so happens to be in its arsenal of features to help you do this.
To flush the DNS cache with CleanMyMac first you’ll need to download it — you can do that here for free.
Then…
- Launch CleanMyMac.
- Click on Maintenance from the sidebar menu.
- Select Flush DNS Cache.
- Click Run.
That’s it. Your DNS is all clear and everything should be back to normal. Or you can try one or more of the following methods.
How to clear the DNS: The manual way
Before we get started, note that resetting the DNS cache will interrupt active web browsing activity so it’s worth closing your browser before performing a flush.
How to flush the DNS cache in macOS High Sierra
1. Open the Finder and go to Applications > Utilities > Terminal.
2. Enter the following syntax at the command line:
sudo killall -HUP mDNSResponder; sleep 2; echo macOS DNS Cache Reset | say
3. Press Return, enter your password, and press Return again.
4. You should now see a message saying “macOS DNS cache reset.”
5. Exit the Terminal.
How to flush the DNS cache in macOS Sierra
Flushing the DNS cache on macOS Sierra is a near identical process to High Sierra, however, the syntax is different.
1. Open the Finder and go to Applications > Utilities > Terminal.
2. Enter (or copy-and-paste if it’s easier) the following syntax at the command line:
sudo killall -HUP mDNSResponder;say DNS cache has been flushed
3. Press Return, enter your password, and press Return again.
4. Listen out for the audio alert to signal that the cache has been successfully cleared.
If for some reason the above syntax doesn’t work, you can use the following syntax in the Terminal instead:
sudo killall -HUP mDNSResponder;sudo killall mDNSResponderHelper;sudo dscacheutil -flushcache;say MacOS DNS cache has been cleared
How to flush the DNS cache in Mac OS X El Capitan and Yosemite
The Mac OS X DNS Flush for El Capitan and Yosemite 10.10.4 and newer is thankfully the same. Both versions use the mDNSResponder.
1. Open the Finder and go to Applications > Utilities > Terminal.
2. Enter the following syntax at the command line:
sudo dscacheutil -flushcache;sudo killall -HUP mDNSResponder;say cache flushed
3. Press Return, enter your password, and press Return again.
4. Wait for the audio alert to signal a successful flush.
5. Exit the Terminal.
For OS X Yosemite versions 10.10, 10.10.1, 10.10.2, and 10.10.3 the process is slightly different. To fully flush all DNS caches, you’ll need to clear both the Multicast DNS (MDNS) and Unicast DNS (UDNS).
- Clearing the MDNS cache
Follow the same instructions as above and enter this syntax in the Terminal:
sudo discoveryutil mdnsflushcache
- Clearing the UDNS cache
Follow the same instructions as above and enter this syntax in the Terminal:
sudo discoveryutil udnsflushcaches
- Clearing both MDNS and UDNS caches
There’s also the option to combine MDNS and UDNS commands to flush both caches at once:
sudo discoveryutil mdnsflushcache;sudo discoveryutil udnsflushcaches;say flushed
How to flush the DNS cache in older versions of Mac OS X
Very few people are still working on older versions of Mac, but “very few” is still some. So, for the 3.8% of Mac owners using OS X Mavericks and the 1.6% using OS X Snow Leopard, here are the instructions for an old-school OS X DNS flush.

Clearing the DNS cache isn’t something you’ll have to do often but it’s a good way to troubleshoot named server errors. Use the correct command for your operating system and you’ll be able to resolve issues within seconds. If, for whatever reason, the command doesn’t work or you don’t feel confident using the Terminal, CleanMyMac will do the job for you.
