Your Sophos anti-virus software is crashing a LOT. Uninstall it, and do not reinstall it.

My Apple Macbook Pro running OS X Yosemite freezes 10.10.1 regularly. When it freezes the only remedy is to physical shut the screen. I don't use any external devices.

My Apple Macbook Pro running OS X Yosemite freezes 10.10.1 regularly. When it freezes the only remedy is to physical shut the screen and wait for the battery to run down. I do not run any external devices, and when it freezes you cannot do anything with the computer. It is new, and this problem is very frustrating. Any suggestions?
Thanks

These instructions must be carried out as an administrator. If you have only one user account, you are the administrator.
Launch the Console 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 and start typing the name.
Step 1
For this step, the title of the Console window should be All Messages. If it isn't, select
          SYSTEM LOG QUERIES ▹ All Messages
from the log list on the left. If you don't see that list, select
          View ▹ Show Log List
from the menu bar at the top of the screen.
In the top right corner of the Console window, there's a search box labeled Filter. Initially the words "String Matching" are shown in that box. Enter "BOOT_TIME" (without the quotes.)
Each message in the log begins with the date and time when it was entered. Select the BOOT_TIME log message that corresponds to the last boot time when you had the problem. Now clear the search box to reveal all messages. Select the ones logged before the boot, during the time something abnormal was happening. Copy them to the Clipboard by pressing the key combination command-C. Paste into a reply to this message by pressing command-V.
For example, if the system was unresponsive or was failing to shut down for three minutes before you forced a restart, post the messages timestamped within three minutes before the boot time, not after. Please include the BOOT_TIME message at the end of the log extract—not at the beginning.
If there are long runs of repeated messages, please post only one example of each. Don’t post many repetitions of the same message.
When posting a log extract, be selective. A few dozen lines are almost always more than enough.
Some private information, such as your name, may appear in the log. Anonymize before posting.
Please don't indiscriminately dump thousands of lines from the log into this discussion.
Please don't post screenshots of log messages—post the text.
Step 2
In the Console window, select
          DIAGNOSTIC AND USAGE INFORMATION ▹ System Diagnostic Reports
(not Diagnostic and Usage Messages) from the log list on the left. If you don't see that list, select
          View ▹ Show Log List
from the menu bar.
There is a disclosure triangle to the left of the list item. If the triangle is pointing to the right, click it so that it points down. You'll see a list of reports. A crash report has a name that begins with the name of the crashed process and ends in ".crash". A panic report has a name that begins with "Kernel" and ends in ".panic". A shutdown stall report has a name that ends in ".shutdownstall". Select the most recent of each, if any. The contents of the report will appear on the right. Use copy and paste to post the entire contents—the text, not a screenshot. It's possible that none of these reports exists.
I know the report is long, maybe several hundred lines. Please post all of it anyway.
If you don't see any reports listed, but you know there was a crash or panic, you may have chosen Diagnostic and Usage Messages from the log list. Choose DIAGNOSTIC AND USAGE INFORMATION instead.
In the interest of privacy, I suggest that, before posting, you edit out the “Anonymous UUID,” a long string of letters, numbers, and dashes in the header of the report, if it’s present (it may not be.)
Please don’t post other kinds of diagnostic report—they're very long and rarely helpful.

My MacBook Pro, running 10.7.3, does not recognize when my iPhone and iPad are on the same network, thus it does not synch. Any ideas?

My MacBook Pro, running 10.7.3, does not recognize when my iPhone and iPad are on the same network, thus it does not synch. Any ideas?

Try the basics first:
Change your router channel number. Most times this works & is all you have to do.
Disconnect & reconnect your modem. unplug it for about 10 seconds. Plug it back in. Do the same for Apple’s routers. Wait for everything to reboot.
System Preferences>Network
Click the Assist Me button.
In the next window that pops up, click the Diagnostic button & do the necessary.

Why is my macbook pro running so slow and losing internet connection?

Why is my Macbook Pro downloading so slowly and losing internet connection frequently?

Write off the MS stuff as indicators for now--starting with Office 2008, they developed very long launch times. The time to launch 2008 on my old 1.25Ghz G4 and my MBP 2.2G are virtually the same. Even document opens/saves are slow compared to Office 2004 and earlier.
1) You have adequate hard drive space so that eliminates one of the usual suspects.
2) Check for runaway background processes. Quit all running user applications so the computer is at normal idle. Find Activity Monitor in Applications > Utilities and launch it. If you've not run it before, change the "Show" pulldown at the top of the AM window from its default of "User Processes" to "All Processes." There is a column for "%CPU." Click that column header to sort by CPU usage. Watch the processes "bubble" for about a minute to get a better picture of the usage.
If any process is using more than about 25 percent of the CPU cycles while the computer is idling, post the names of the processes and we can see if they can be eliminated. My MBP shows nothing using more that about 5 percent on any given test run as long as I close all my user apps.
3) If you have never done any sort of maintenance procedures, taht can slow you down. Simply restarting the computer a few times a week clear a lot of temporary files. You also may wish to review this article on the Mac OSX periodic maintenance scripts, which, if run, also do a lot of cleanup:
http://thexlab.com/faqs/maintscripts.html
There are other useful articles on file maintenance associated with the one. Here's the index:
http://thexlab.com/faqs/faqs.html
Check out articles with "Maintain" and "Tuning" in the titles.
4) Use Disk Utility to check the SMART Status of your hard drive. A failing drive can make things slow before it makes things stop.

I have a macbook pro running lion and it will not log on to a microsoft exchange server. any suggestions

i have a macbook pro running lion and cannot log on to my microsoft exchange server. Not a problem with my iphone and ipad are there any issues or fixes for this?

I found the following suggested fix, posted by a user on Barnes & Noble's site:
1. Create a folder in your Applications folder, call it: NOOKforMac
Once you've done this, copy the Nook app to this folder. This should allow the app to run on the 1st or possibly second attempt to launch it.
2. Once you're done using the app always quit it by clicking on the X (red in some cases) button of the application window (upper left hand corner)
This seems to have resolved the issue and my guess is that somehow the .dmg volume path is somewhere hard coded in the app configuration.
Elsewhere in that thread, the administrator advises calling Customer Service Team at 1-800-THE-BOOK (1-800-843-2665) and choose option 2 for Digital Support.
Good luck.

MacBook Pro running mountain lion restarts with Ethernet connected

Hi all,
My MacBook Pro (early 2012 15") running Mountain Lion (10.8.1) seems to always restart whenever I connect it to an Ethernet. The wireless works fine and there are no problems. The Ethernet connects then about a minute later my MacBook just restarts no matter what I am doing. I have gotten a new Ethernet cable but the same issue keeps happening. I haven't been able to try another Ethernet port as of yet, I am at school so mine might not work correctly however the Ethernet works fine for my friends PCs.
Does anyone have any ideas that could help me? I would really like to use Ethernet because the wireless here tends to be slow.
Thank you!

I realize no one has responded to this but I am still having the issue even after a month. I also now have a panic report if that helps at all.

MacBook Pro running amazingly slow (formatting DID not work)

I own a MacBook Pro with OS X installed on it, and it suddenly started running very slow.
It happened literally overnight. One day it was working, the next morning it wasnt. I tried formatting the hard drive via the disk utility when starting the MacBook, but it didnt work. I also tried to delete my Windows partition, but it didnt allow me (though I dont believe that is a problem, since the last time I used it was over a year ago).
Anybody has any ideas?
Thanks for your help,
Andre.

Suggestions of Things You Can Do To Help A Slow Computer
If your computer seems to be running slower here are some things you can do:
Start with visits to:     OS X Maintenance - MacAttorney;
                                  The X Lab: The X-FAQs;
                                  The Safe Mac » Mac Performance Guide;
                                  The Safe Mac » The myth of the dirty Mac;
                                  Mac maintenance Quick Assist.
Boot into Safe Mode then repair your hard drive and permissions:
Repair the Hard Drive and Permissions Pre-Lion
Boot from your OS X Installer disc. After the installer loads select your language and click on the Continue button. When the menu bar appears select Disk Utility from the Utilities menu. After DU loads select your hard drive entry (mfgr.'s ID and drive size) from the the left side list. In the DU status area you will see an entry for the S.M.A.R.T. status of the hard drive. If it does not say "Verified" then the hard drive is failing or failed. (SMART status is not reported on external Firewire or USB drives.) If the drive is "Verified" then select your OS X volume from the list on the left (sub-entry below the drive entry,) click on the First Aid tab, then click on the Repair Disk button. If DU reports any errors that have been fixed, then re-run Repair Disk until no errors are reported. If no errors are reported click on the Repair Permissions button. Wait until the operation completes, then quit DU and return to the installer.
Repair the Hard Drive - Lion/Mountain Lion/Mavericks
Boot to the Recovery HD:
Restart the computer and after the chime press and hold down the COMMAND and R keys until the Utilites Menu screen appears. Alternatively, restart the computer and after the chime press and hold down the OPTION key until the boot manager screen appears. Select the Recovery HD disk icon and click on the arrow button below.
When the recovery menu appears select Disk Utility. After DU loads select your hard drive entry (mfgr.'s ID and drive size) from the the left side list. In the DU status area you will see an entry for the S.M.A.R.T. status of the hard drive. If it does not say "Verified" then the hard drive is failing or failed. (SMART status is not reported on external Firewire or USB drives.) If the drive is "Verified" then select your OS X volume from the list on the left (sub-entry below the drive entry,) click on the First Aid tab, then click on the Repair Disk button. If DU reports any errors that have been fixed, then re-run Repair Disk until no errors are reported. If no errors are reported, then click on the Repair Permissions button. Wait until the operation completes, then quit DU and return to the main menu. Select Restart from the Apple menu.
Restart your computer normally and see if this has helped any. Next do some maintenance:
For situations Disk Utility cannot handle the best third-party utility is Disk Warrior; DW only fixes problems with the disk directory, but most disk problems are caused by directory corruption; Disk Warrior 4.x is now Intel Mac compatible.
Note: Alsoft ships DW on a bootable DVD that will startup Macs running Snow Leopard or earlier. It cannot start Macs that came with Lion or later pre-installed, however, DW will work on those models.
Suggestions for OS X Maintenance
OS X performs certain maintenance functions that are scheduled to occur on a daily, weekly, or monthly period. The maintenance scripts run in the early AM only if the computer is turned on 24/7 (no sleep.) If this isn't the case, then an excellent solution is to download and install a shareware utility such as Macaroni, JAW PseudoAnacron, or Anacron that will automate the maintenance activity regardless of whether the computer is turned off or asleep. Dependence upon third-party utilities to run the periodic maintenance scripts was significantly reduced since Tiger. These utilities have limited or no functionality with Snow Leopard or later and should not be installed.
OS X automatically defragments files less than 20 MBs in size, so unless you have a disk full of very large files there's little need for defragmenting the hard drive.
Helpful Links Regarding Malware Protection
An excellent link to read is Tom Reed's Mac Malware Guide.
Also, visit The XLab FAQs and read Detecting and avoiding malware and spyware.
See these Apple articles:
          Mac OS X Snow Leopard and malware detection
          OS X Lion- Protect your Mac from malware
          OS X Mountain Lion- Protect your Mac from malware
          About file quarantine in OS X
If you require anti-virus protection I recommend using VirusBarrier Express 1.1.6 or Dr.Web Light both from the App Store. They're both free, and since they're from the App Store, they won't destabilize the system. (Thank you to Thomas Reed for these recommendations.)
Troubleshooting Applications
I recommend downloading a utility such as TinkerTool System, OnyX, Mavericks Cache Cleaner, or Cocktail that you can use for removing old log files and archives, clearing caches, etc. Corrupted cache, log, or temporary files can cause application or OS X crashes as well as kernel panics.
If you have Snow Leopard or Leopard, then for similar repairs install the freeware utility Applejack. If you cannot start up in OS X, you may be able to start in single-user mode from which you can run Applejack to do a whole set of repair and maintenance routines from the command line. Note that AppleJack 1.5 is required for Leopard. AppleJack 1.6 is compatible with Snow Leopard. Applejack does not work with Lion and later.
Basic Backup
For some people Time Machine will be more than adequate. Time Machine is part of OS X. There are two components:
1. A Time Machine preferences panel as part of System Preferences;
2. A Time Machine application located in the Applications folder. It is
    used to manage backups and to restore backups. Time Machine
    requires a backup drive that is at least twice the capacity of the
    drive being backed up.
Alternatively, get an external drive at least equal in size to the internal hard drive and make (and maintain) a bootable clone/backup. You can make a bootable clone using the Restore option of Disk Utility. You can also make and maintain clones with good backup software. My personal recommendations are (order is not significant):
1. Carbon Copy Cloner
2. Get Backup
3. Deja Vu
4. SuperDuper!
5. Synk Pro
6. Tri-Backup
Visit The XLab FAQs and read the FAQ on backup and restore. Also read How to Back Up and Restore Your Files. For help with using Time Machine visit Pondini's Time Machine FAQ for help with all things Time Machine.
Referenced software can be found at MacUpdate.
Additional Hints
Be sure you have an adequate amount of RAM installed for the number of applications you run concurrently. Be sure you leave a minimum of 10% of the hard drive's capacity as free space.
Add more RAM. If your computer has less than 2 GBs of RAM and you are using OS X Leopard or later, then you can do with more RAM. Snow Leopard and Lion work much better with 4 GBs of RAM than their system minimums. The more concurrent applications you tend to use the more RAM you should have.
Always maintain at least 15 GBs or 10% of your hard drive's capacity as free space, whichever is greater. OS X is frequently accessing your hard drive, so providing adequate free space will keep things from slowing down.
Check for applications that may be hogging the CPU:
Pre-Mavericks
Open Activity Monitor in the Utilities folder. Select All Processes from the Processes dropdown menu. Click twice on the CPU% column header to display in descending order. If you find a process using a large amount of CPU time (>=70,) then select the process and click on the Quit icon in the toolbar. Click on the Force Quit button to kill the process. See if that helps. Be sure to note the name of the runaway process so you can track down the cause of the problem.
Mavericks and later
Open Activity Monitor in the Utilities folder. Select All Processes from the View menu. Click on the CPU tab in the toolbar. Click twice on the CPU% column header to display in descending order. If you find a process using a large amount of CPU time (>=70,) then select the process and click on the Quit icon in the toolbar. Click on the Force Quit button to kill the process. See if that helps. Be sure to note the name of the runaway process so you can track down the cause of the problem.
Often this problem occurs because of a corrupted cache or preferences file or an attempt to write to a corrupted log file.

Macbook Pro (Lion 10.7.3) will not connect to Wi-Fi -- persistant 'connection time-out', and fails.

I can see this seems to be a common problem, and it is amazing that there seems to be no consensus (that I can find) on what the underlying problem is.
Here are the basics.... I have two Macbook Pro 13's... Pretty much identical setups (Lion 1.7.3 etc.).
One, works flawlessly connecting to Wi-Fi - whether that is my Airport Express, or any other open or closed networks.
The second, will continually refuse to connect -- to the Airport Express or even a wide-open 802.11b network. It will continually pop up the "connection timeout" erorr, and refuse to connect...
Iphones etc all connect perfectly... Even when connecting to the iPhone hotspot - the same error.
This will happed consistently, until I give up. I can leave it for a day (use ethernet), and come back tomorrow, and voila - it will connect. I may be able to use it for a day or several, but once it decides to 'fail', there is virtually nothing I can do to bring it back... it will continue to fail over and over again.
All updates are applied, I've cleaned out all other networks etc from the list. Tried all civilized things that I can.
Thoughts? Anyone have any other insight? Think this could be a hardware issue? I was thinking to yank the wi-fi module from the working notebook to the non-working one as a test...
Thanks,
Brad

Change your router channel number. Most times this works & is all you have to do.
System Preferences>Network
Click the Assist Me button.
In the next window that pops up, click the Diagnostic button & do the necessary.

MacBook Pro to Samsung sound bar Bluetooth not connecting

Hello all,
I recently purchased a Samsung sound bar with bluetooth connectivity. I can connect my iPhone 5s to it and stream music with no problem. But when I try to connect my MacBook Pro, it simply connects and promptly disconnects. I have tried shut down, restart, and even unplugging the battery on the MacBook with no luck.
I am running OSX 10.9.3 with all available updates.
Has anyone else had this problem?
Thanks,
Jerry

Same here I'm using a Samsung HW-H550 Sound Bar - Connect's with iPhone/iPad on IOS 7.1.1 on my Mac Book Pro Retina OS X 10.9.3. Having no joy even went down the root of deleting the Bluetooth Pref file didn't work either.
Looking forward to any workable solution

Macbook Pro Mini Display Port To HDMI Not Connecting To Sony Bravia KDL-52XBR9 And Any HDMI TV's In My House

I have a Macbook Pro (Mid 2010) and recently purchased a mini DVI to HDMI cable. I was using it perfectly fine on my LG TV for a while but than one day I plugged it in and it just stopped working. The Macbook Pro screen would flash blue for a few seconds than return to normal as if nothing was plugged in. I tried detect displays and everything and it sill does not work. I tried it on 4 HDMI inputs on TV's in my house and none of them are working. Does anyone have any idea on what's wrong? I didn't change the settings at all. Just plugged it in than it stopped working. Anyone know whats wrong?

Hi 1,
You are far from the first to experience this issue. An SMC Reset may resolve some video issues, although this scenario is not listed; still, I would try it: http://support.apple.com/kb/HT3964

Why does my Macbook Pro run slow if it's not on the Charger?

My macbooks running terribly slow and I've tried everything. The only thing I've noticed is that it runs faster on the charger. The mouse is super laggy and it's been like this for a couple weeks now. I restored my whole computer, clear cookies, ran updates, cleared disks, etc. Has anybody else had this problem before?

Try a smc reset:

Follow directions for a battery you should not remove yourself.

Macbook Pro thinks wireless mouse or trackpad not connected, keyboard and trackpad nonrespsonive

Hi,
I have a 2009 MB Pro. It is now displaying a screen that says "Bluetooth Mouse or Trackpad Setup: There isn't a wireless mouse or trackpad connected" and then it says it is looking for a wireless mouse or trackpad and is just spinning. It says if you don't want to set up a mouse or trackpad press commad-Q to quit, but both my trackpad and built in keyboard are now completely non-functional, so I can't get out of this screen. This is weird because I have never used a wireless mouse or keyboard on this computer. The only options it gives me at the bottom are to put the computer to sleep, restart or shut down. I have no idea how to make my keyboard or mouse functioning again. Any help would be much appreciated. Thank you.
-Max

sorry you say your built in trackpad. and your built in keyboard. reboot. reset your pram. maybe your smc
see if that helps

My Macbook Pro running Lion 10.7 will no longer connect to either my HP or Epson printers. Both printers report that they are connected to the correct wireless network and until 2 weeks ago work perfectly.

My Macbook pro running Lion 10.7 will not connect via a wireless network to either of my printers, Epson and HP. Both printers report an excellent connection to the correct network. The Macbook reports "printer not found"
Until 2 weeks ago all worked well. Both printers makes me think some setting in the computer must have changed.
Any suggestions?

System Preferences>Fax & Scan. Delete the printers and re-add them back in.
