My MacBookPro is less than 3 months old and for the last few days, it has been itslow to load anything, especially web pages. I get the rainbow swirl when loading or reloading. I guess I am spoiled. Up until now it was lightening fast!

Question

My MacBookPro is less than 3 months old and, for the last few days, it has been loading so slowly, mainly with webpages.  I have gotten the swirling rainbow "thinking" icon more in the last days than I have since I bought it.  I know I'm spoiled and expect it to be faster than lightening (which it has been) but I am worried that I may have been compromised in some way, or, is there anything I can do as administrator to clear out some "junk"?

Answer 1

Back up your documents and everything else important to you, not that there is any reason to believe your hard disk may be failing, but the symptoms you describe may presage an impending disk failure, and you should have backups anyway.
Given that your MacBook Pro is so new, you should certainly contact AppleCare and take advantage of the free telephone support included in its purchase price.
Until then, if you are motivated to investigate this yourself consider the following:
Apple Support Communities contributor etresoft wrote a very useful app to quickly gather certain system information that may help point to a cause of this problem. Go to his website, download and run EtreCheck:

Etrecheck will be in your Downloads folder. Open it from there. You may see the following dialog box:

It will take a moment to run as it collects its data.
Copy and paste its output in a reply.
Do not be concerned about anything that says "Problem" or "failed".
EtreCheck was designed to remove any personal information (such as your computer's name and serial numbers) but if you see anything that looks like an email address or any other personal information that should not be divulged to others, please delete or obscure that information when you post the reply.
When you are finished with EtreCheck, quit the program. It occupies very little space, and you can keep it or drag it to the Trash as you wish.
