27' imac is slow to navigate and download from the net, and the computer freezes while on the net, what could be causing this issue?

can anybody answer this question

Johnso,
Please complete your profile so we at least know a little more about your system, Apple has made quite a few 27" iMac models using different versions of OS X so it would be helpful to us if we knew the model you had and the version of OS X installed.
PLEASE complete your profile, you can find it under Your Stuff and Profile in the upper right of this page.

HT4009 I keep getting a message to contact itunes support when I try to make an in app purchase. What could be causing this issue? My credit card is up to date and in app purchases aren't restricted.

Have you tried contacting iTunes Support and asking them ? We are fellow users here on these forums, it could be due to a number of reasons, we won't know which one.

Install it directly from Adobe. Ensure that you use the uninstaller before installing.

I've just downloaded Sophos (yesterday) and commenced the scan. It keeps stopping part way through, the 2nd time when it was about 98% completed after 4 hours!!!! I've had to start again. What could be causing this? I have Mountain Lion.

FWIW, I have used Sophos regularly for several years now (including on my new iMac running Mountain Lion versions 10.8.2 & now 10.8.3) & never had any problems with it on any of the half dozen or so Macs I have installed it on.
Quite a few people automatically assume all Mac A-V software is troublesome junk, & many will leap to the conclusion it is the cause of some problem without considering other potential (& often much more likely) causes, regardless of which A-V product is installed.
Obviously I hope, not all A-V products are alike, so it doesn't make a lot of sense to me to condemn them all because of problems with one of them. Regarding Sophos in particular, finding first hand reports of it causing problems is quite difficult -- typically, if you ask for the details it turns out to be a second or third hand report & there isn't enough info available to know for certain if it is the real cause or not.
This is not to say it is impossible for it to cause problems, just that it is prudent to consider all the possibilities before concluding that any one of them is the cause.

ITunes on new Macbook Air is slow and laggy after a few minutes. What could be causing this?

I recently updated from PC to a 2013 Macbook Air i5 with an upgraded 8GB of memory and I copied over my iTunes library. However, when I've been using iTunes for a few minutes (specifically after editing the info of one of more songs), it gets very laggy and slow. I then have to quit iTunes and re-open it for it to run smoothly again. Anyone have any ideas what could be causing this?

Ignore all other sounds except at time frame 3 to 5 seconds in this video http://www.youtube.com/watch?v=0edpFdRZyFo
If your macbook is making that noise being woken from sleep mode, its normal and the noise of the laser tray. in the superdrive resetting, disk or no disk. (ignore the fact the video says 2010 macbook, superdrive makes the same sound).
Is that the noise you are hearing?
Ah yes, heres the SMS sensor sound > is that it?
http://www.youtube.com/watch?v=66xMoTEFH7Q
Thats a protection sound of the HD heads parking themselves to protect the HD from damage. Are you moving the Macbook at all when you hear the sound?

Thanks for the suggestion, the next step was to call Apple, who gave me a claim number, which I discovered you must have to get anything done with them. They refered me to a Apple store or repair center, after some reseach took it to the Computer Store in Mobile, Alabama and they were excellent. They took pictures of the screen with bug submitted it to Apple who denied the claim but they kept kicking it up to the next level and finally Apple agreed to sent new cover. The Computer Store had the cover the next day, they changed it out and now I am bug free. If your in the area of Mobile Alabama you can feel good about getting help from the Computer Store. For the two folks that responded to my note, Thank You, good comments and good advice.

How to Remove “Other” Data from iPhone, iPad and iPod Touch
http://www.igeeksblog.com/how-to-remove-other-data-from-iphone/
With an iOS device, the “Other” space in iTunes is used to store things like documents, settings, caches, and a few other important items. If you sync lots of documents to apps like GoodReader, DropCopy, or anything else that reads external files, your storage use can skyrocket. With iOS 5/6/7, you can see exactly which applications are taking up the most space. Just head to Settings > General > Usage, and tap the button labeled Show All Apps. The storage section will show you the app and how much storage space it is taking up. Tap on the app name to get a description of the additional storage space being used by the app’s documents and data. You can remove the storage-hogging application and all of its data directly from this screen, or manually remove the data by opening the app. Some applications, especially those designed by Apple, will allow you to remove stored data by swiping from left to right on the item to reveal a Delete button.

I purchased a refurbished iBook G4-Version 10.4.11 and everytime that I try to purchase anything on iTunes or change something in my account, I click "done" and it says that I have timed out. What could be causing this?

I purchased a refurbished iBook G4-Version 10.4.11 and everytime that I try to purchase anything on iTunes or change something in my account, I click "done" and it says that I have timed out, when I'm on there for less than a minute. Hence, none of my purchases have gone through.What could be causing this?

You need to use a newer Mac OS X version. A G4 can be upgraded to 10.5.8(if desired, buy a retail DVD from a source such as Amazon or eBay), but you'll likely find it more cost-effective to buy a secondhand Intel Mac.

My iPad isn't working properly. When I try to connect to the internet or follow a link it shuts down and returns to the main screen. Any clue as to what could be causing this? Not my internet connection, I checked that.

My iPad isn't working. I cannot follow a link in an email or connect to a game. It goes to a black screen then back to the main screen. Any idea what could be causing this?

Settings > General > Reset > Reset Network Settings
Perform a "hard reset" on the device by pressing down and holding the home button and the sleep/wake button for up to 30secs. until you see a black screen with the Apple logo, then release.
Then test to see if it solved the problem.

Unable to sync iPad and PC. Keeps crashing. Lost my music, films and photos. What could be causing this?

My sync session keeps failing and I can't upload any photos, films or music to my iPad. As a result iTunes keeps crashing. All systems are up to date. What could be causing this?

Have you considered a Restore? http://support.apple.com/kb/ht4097
First, uninstall iTunes, reboot your computer, reinstall iTunes and try another sync.

I finally resolved my problem after spending way too much time on it. I simply handed my 160GB iPod to my husband to put his fav Stones & Beatles songs on and I went back to my 80GB Microsoft Zune which has never disappointed me.
After spending so much time trying to figure this out I did finally take it back to Apple Store who performed a diagnostic and found there was a problem with the device. They replaced it with a refurbished one which has similar issues. All I wanted to do was listen to my music. Was that too much to ask? So I am happy to be free of this problematic device. No more Apple for me!!

If you have anti virus software installed, disable that.
Try turning off the Firewall in System Preferences > Security

It would help when you post to tell us which Mac OS X you have installed. Thank you !!

Hi, my MacBook Pro has become very slow... what could be causing this and what can I do to fix it?

Hi, my MacBook Pro is working very slowly.. what could be causing it and what can I do to fix it??

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.
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.

Recently, any attempt to log on to any site with my valid userid and password fails with FireFox but passes with Internet Explorer. What could possibly cause this?

I used FireFox a long time for email and other scure sites. Out of the blue my logins started rejecting. In frustration, I went back to Internet Explorer and found I could log in using the same UID and PWD.
I cain't imagine what setting could be causing this to happen. Have you ever heard of such a thing? And is there a solution?

In Firefox 3.6.4 and later the default connection settings have been changed to "Use the system proxy settings".
See "Firefox connection settings" in [[Server not found]]
You can find the connection setting here: Tools > Options > Advanced : Network : Connection
If you do not need to use a proxy to connect to internet then select No Proxy
Another possible cause is security software (firewall) that blocks or restricts Firefox without informing you about that,.
Remove all rules for Firefox from the permissions list in the firewall and let your firewall ask again for permission to get full unrestricted access to internet for Firefox.
