laggy MBP 15'' after only a month...

[PurpleShaman]

i purchased my base 15'' MBP around a month ago. everything was pretty good until around a week ago. I installed a couple of plugins for firefox, and things have been pretty laggy recently. Browsing site like ESPN have become choppy and even scrolling around the iTunes store has been laggy. I uninstalled Firefox and it's still still laggy with Chrome and Safari. Is there any way I can manually uninstall plugins? I feel like this might have something to do with Flash...How can I fix this?

thanks!

Have a look at Activity Monitor ( Applications / Utilities / ) and select All Processes and sort by CPU to see what the culprit may be.

image below uses sorting by CPU as an example

To properly uninstall applications:

To manually remove an application and all associated files:

1. Launch Finder and search for the app name (hopefully unique, such as Skype)
2. You can narrow the search to specific folders or search your whole Mac
3. Searching "File Name" vs "Contents" usually provides better results.
4. Click the + button below the search term to add criteria
5. Click the "Album" drop-down and select "System files"
6. Click the "Don't include" and change to "include"
7. Sort by name, kind, date, etc. to identify components of the app, such as folders, .plist files, cache files. etc.
8. Delete all files and folders related to the app.
9. Don't empty your Trash until you've determined that everything is working OK, in case you need to restore something you deleted by accident.
10. A reboot might be necessary to completely remove some apps.

Check to see if you have a document trying to print that can not be done. It is a usual suspect in cases like these.

To uninstall apps, I think it's better to use CleanMyMac

Might be failing HDD... if everything in your system (like CPU load, RAM usage) checks out, it might be your HDD is failing.

Did this happen before you got Chrome? I would get rid of Chrome. Firefox and Safari are good enough.
