My Mac Book Pro has slowed to less than a crawl (possibly from a worm or virus). How do I make sure it's running at peak efficiency before I complain to comcast

Please answer as many of the following questions as you can. You may already have answered some of them; in that case, there's no need to repeat the answers.
Restart the router and the broadband device, if they're separate. Any change?
Run Software Update and install all available updates for OS X or the computer's firmware. Any change?
If possible, connect to the router with an Ethernet cable and turn off Wi-Fi. Any difference?
Are any other devices on the network, and if so, are they the same?
If you can connect to more than one network, are they all the same?
Are all network applications affected, or only some? If only some, which ones?
Is networking always the same, or is the problem intermittent?
Disconnect all other devices from the network. Any change?
If you're running a MacBook with the lid closed, open the lid. Any difference?
Start up in safe mode and test. Any difference?
Start up in Recovery mode. From the OS X Utilities screen, select Get Help Online. A clean copy of Safari will launch. No plugins, such as Flash, will be available. Any difference?
If possible, turn off Bluetooth and disconnect any USB 3 devices. Any difference?

Mac book pro has become very slow. How to analyze this and resolve this?

My mac book pro has become very slow. How to analyze and resolve this?

First, back up all data immediately, as your boot drive might be failing.
There are a few other possible causes of generalized slow performance that you can rule out easily.
Reset the System Management Controller.
If you have many image or video files on the Desktop with preview icons, move them to another folder.
If applicable, uncheck all boxes in the iCloud preference pane.
Disconnect all non-essential wired peripherals and remove aftermarket expansion cards, if any.
Check your keychains in Keychain Access for excessively duplicated items.
Boot into Recovery mode, launch Disk Utility, and run Repair Disk.
If you're booting from an aftermarket SSD, see whether there's a firmware update for it.
Otherwise, take the steps below when you notice the problem.
Step 1
Launch the Activity Monitor application in any of the following ways:
☞ Enter the first few letters of its name into a Spotlight search. Select it in the results (it should be at the top.)
☞ In the Finder, select Go ▹ Utilities from the menu bar, or press the key combination shift-command-U. The application is in the folder that opens.
☞ Open LaunchPad. Click Utilities, then Activity Monitor in the icon grid.
Select the CPU tab of the Activity Monitor window.
Select All Processes from the menu in the toolbar, if not already selected.
Click the heading of the % CPU column in the process table to sort the entries by CPU usage. You may have to click it twice to get the highest value at the top. What is it, and what is the process? Also post the values for % User, % System, and % Idle at the bottom of the window.
Select the System Memory tab. What values are shown in the bottom part of the window for Page outs and Swap used?
Next, select the Disk Activity tab. Post the approximate values shown for Reads in/sec and Writes out/sec (not Reads in and Writes out.)
Step 2
If you have more than one user account, you must be logged in as an administrator to carry out this step.
Launch the Console application in the same way you launched Activity Monitor. Make sure the title of the Console window is All Messages. If it isn't, select All Messages from the SYSTEM LOG QUERIES menu on the left. If you don't see that menu, select
View ▹ Show Log List
from the menu bar.
Select the 50 or so most recent entries in the log. Copy them to the Clipboard (command-C). Paste into a reply to this message (command-V). You're looking for entries at the end of the log, not at the beginning.
When posting a log extract, be selective. Don't post more than is requested.
Please do not indiscriminately dump thousands of lines from the log into this discussion.
Important: Some personal information, such as your name, may appear in the log. Anonymize before posting. That should be easy to do if your extract is not too long.

Hello, I'm pretty sure my fan on my 2009 mac book pro has stopped running. Would this cause the computer to slow down and take for ever to boot up and show the color wheel every time I select an application ?

Hello, I'm pretty sure my fan on my 2009 mac book pro has stopped running. Would this cause the computer to slow down and take for ever to boot up and show the color wheel every time I select an application ? how involved to replace fan ? cost ?

Not directly, but if the CPU overheats because of incompatible software, that would cause slowdowns. Do not allow the computer to run if the fan is not working unless you wish to fry your motherboard. Please make a Genius Appointment and take it in for service.

My mac book pro speed slow

speed slow problem for my mac book pro

My mac book pro has an i7 processor, and still slow. The monitor of activity, when the computer just turned on says 1.8 GB in use (or more). Is it OS Lion?, because the amount of processes in the list don´t use much memory. Programs have a delay to open, close, save, etc. Y can´t have more than 4 or 5 programs running and my memory decreases dramatically. My disk has 140 GB free. I´ll be very thankfull if I can have some help.

My mac book pro has a white screen and won't start up

My Mac book pro has been running slow, so I thought I would shut down and reboot. It wouldn't reboot past a white screen and an apple logo. I have rebooted several times and after an hour or so it still won't go any further. Any suggestions?

Howdy Lowana42,
Welcome to Apple Support Communities.
It sounds like your MacBook Pro has a startup issue that is causing it to only display an Apple logo. Try the suggestions in the article below, they will resolve most issues like this one.

You can use iCloud to lock it if you had that set up. Otherwise, the only thing to do is report the theft to the police. You may want to contact your homeowner's insurance to see if it would be worth filing a claim with them also.

Why is my computer slow?

My Mac Book Pro is slow and at times I have to reboot to connect to the net

My Mac Book Pro is slow and at times I have to reboot to connect the net. Also wondering how do I check if my software is up to date? Thank you.

To check to see if your software is up to date, go to >Software Update and you can check for updates.
No idea why your Mac is slow--there could be a variety of things that could cause slowness. A good start would be to see if all your RAM is recognized. >About this Mac will show you how much RAM you have. You can also open Activity Monitor and check your RAM usage.
Also, how full is your hard drive? You should have a minimum of 10% free space for the OS to operate properly, and 15% to 20% is better.
No idea why you have to reboot to connect to the internet, but it could be related to the slowness. Rebooting will free up RAM among other things.
Which MBP do you have and which version of the OS are you running?

It is highly likely that this attachment is malware. It's also highly likely that it is Windows malware. So you're probably not infected with anything. What is the exact name of the attachment you opened? Please be sure to include whatever extension the filename has (such as .exe, .pdf, .doc, etc).
What happens when you try deleting the attachment files from your desktop? Is there an error message of some kind? If so, what is the exact error message you're seeing? (Please don't try to paraphrase it... tell us the precise wording of the message.)

If you didn't have "Find My Mac" enabled under the iCloud System Preferences pane, there's likely no way to trace your machine over the Internet.
