Two Critical Preventative Maintenance Videos


Do these two routines monthly.

Here are two critical, preventative maintenance routines we should run once a month. Not only will they help protect our data, but our computers will perform better after you run them. Most people see the difference in speed right away. As always, no preventative maintenance routine is better than a great backup strategy. If you do not have a backup strategy, get one in place today.

How to and What For?

Repairing Permissions

These two routines are basic preventative maintenance routines we should run once a month. Permissions repair checks thousands and thousands of files on your computer to make sure they have the correct access privileges as compared to a known state from the permissions database. If it finds changes, it attempts to fix them. This one utility can make your computer feel like it is brand new again. Things just fell better after you run it. Give it a try. It’s easy. Just open Disk Utility, select your Hard Drive volume (the second one, it’s indented) and then click the little button that reads “Repair Permissions.” Make sure you are plugged into a power source if you are using a laptop.



FSCK stands for File System Check. It is run in “Single User Mode.” To put your computer into single user mode, you must restart it while holding down the Command and S key on your keyboard. After the startup chime, you will see your screen go dark and some white text appears on the screen. You can let go of the keys at this point. After the text finishes scrolling, you will see that the last line says something like “root#”. That means it is waiting for you to type the secret command fsck -fy. There is a space between the K and the dash and we use all lower case letters.

After you type that command, type the enter or return key on your keyboard to get things started. This may take several minutes and you will NOT see a lot of action. When the computer finishes running the routine, it will return to the root# prompt. If the last couple of lines indicate that there were problems on the drive or something was repaired, run this command again by typing the “Up Arrow” on your keyboard. When you do that, the fsck -fy command will automatically be retyped for you so you don’t have to type it again. Hit return and away you go again. Repeat the process until you see a message that says “The HD appears to be OK.”

When all is well, type the word “reboot” (lower case) ¬†and hit the return key. You computer will restart and you are good to go.
