How to fix a 'laggy' Macbook Pro?

Recently, my Macbook Pro began to lag a bit. When i toggled from safari to Microsoft Word, the rainbow wheel would pop up. Also, occasionally when i type text it takes a few seconds before the words coordinate with the keys. Does anyone know what the problem is or how to fix it?

Hi drei.flash: Check out the Apple article below as a first test.

Hi: My highest percentage right now is about 9%, so 70% is significant. How much hard drive space is free? It is recommended to have 10-15% free.

I have the same problem I don't have any open applications that take up more then 5%. Furthermore I had 4 gb of DDR3 So I have then upgraded to 8GB of DDR3 with the problem still remaining. If anyone could shed light on this I would appreciate it.

Running 10.6.6 2009 mid 13' macbook pro
8GB DDR3 2.26 Dual core duo

same problem. just did a clean install of 10.6 and still doing it.

Hi there! I am a very novice guy but let me try to help you with what knowledge I have!
1- Leave your Mac open and stop it from going to sleep for a whole night! Sometimes Mac likes to do some house-cleaning and maintenance inside and leaving ti up all night will make sure you've given it enough time to do that!
2- If you have bootcamp-d windows in your Macbook then go to the system preferences and choose spotlight and then under privacy tab, put the BOOTCAMP drive in it so that your Mac stops indexing windows files and settings for the spotlight!
3- Download the cleanmyMac or snowleopard cache cleaner and do a house-cleaning! Mac has the tendency to use a lott of space as cache and virtual storage and those two softwares will make sure you get rid of the unwanted junkies!
4- Before closing the Safari click on the Safari in the menu bar and click on reset safari! A lot of choices will come and you can empty everything over there including history, unless you want safari to remember the webpages you visited!
5- Some of the Apps over time gets corrupted so you can re-check the premission setting and uninstall the unused, corrupted apps.
hope it helps..:) thank you

Some basic repairs perhaps?

Try using Disk Utility to do a Disk Repair, as shown in this link, while booted up on your install disk.

You could have some directory corruption. Let us know what errors Disk Utility reports and if DU was able to repair them. Disk Utility's Disk Repair is not perfect and may not find or repair all directory issues. A stronger utility may be required to finish the job.

After that Repair Permissions.

No need to report Permissions errors....we all get them.

If those don't help, post back.

my macbook has been freezing then unfreezing (spinning beachball) on almost anything i try to click, so i tried to do the disk repair and i can't even get the disk to stay in the computer without it spitting it right back out, what does that mean?

In this case I would download and install AppleJack (372 KB.) Boot into Single User Mode and run AUTO.

One question is what percentage free HD and how much RAM?

i'm not sure how much, where would i figure that out?

One way is under the --> *About this Mac.* It will tell you how many GB of RAM.

Continue with *More Info* --> Hardware --> Serial-ATA if you scroll down and you will see *Macintosh HD* capacity and available.

okay, my capacity is 270 gb because i partitioned my hardrive and available is 102 gb.

I tried using Disk Utility and that did not seem to solve the constant freezing, so now i'm going to try Applejack. If that doesn't work, I have no clue what to do
