The display on my 4 year old iMac has horizontal lines and gradations of gray. Is my machine on its way out? Can I fix the screen?

My four year old iMac has developed horizontal lines and gradations of gray over the last month. Is my machine on its way out? Is there anyway to fix the display?

If you live near an Apple Store, make a Genius Bar appointment to have the computer tested. Supposedly there is no charge for testing.

I plan to buy iMac w/Mountain Lion How do I un-install FCE and MSoft Office 2011 from old iMac and reinstall

How do I uninstall FCE (v 4.0.1) from old iMac (OS 10.6.8 2GHz Intel Core Duo)?
Can I re-install on new iMac I plan to buy with Mountain Lion? I have install FCE CD.

I couldn't remember from my earlier experience what the software was that worked, but I found FCS Remover on my Mac in Applications, so that's what I plan to try.
That will do the job removing all the FCE related files.

And I was surprised to learn the new iMacs don't have a DVD burner which I use all the time on this iMac and my newer Macbook Pro. I suppose that's why the prices start at $1299? I will look, but does the Apple store sell DVD burners? And assuming so, do any of you have recs?
As Keith mentions Apple sells one as an optional extra.
There are others on the market as well.
My experience is to do some serious homework before buying any unit to make sure it is compatible with your specific Mac. Some users have been very disappointed.
I use an OWC (Other World Computing) bluray burner with several types of connections and it works fine.

Lastly, it has taken me about 4 years to master FCE. I am willing to go to FCP X if those here can advise me about 1)how tough is the learning curve if you're good at FCE and 2) is it a better program?
Question 1.
Totally different to FCE and you need to forget most of what you learnt there to adapt to FCP X.
Most dramas occur learning FCP X because users try to think and use FCP X the the old way.
It took me some adjusting to get into the new methods and thinking and terms used.
Advice: Read the manual and unlearn FCE. Search the FCP X forum or ask a specific question, the info there is mounting.
Question 2.
Better is a subjective term.
I have sold all my old legacy FCP stuff and moved on to FCP X.
As a broad statement it makes it easier for someone who knows little about editing and the quirks of codecs to Import and Edit a Project.
That being said the underlying complexity of the app is very powerful.
Like all apps it's not perfect, the current version is 10.0.8 and I made the shift at 10.0.7 when it had matured to the extent I was personnaly happy to make the jump.

How do you clean install CS6 on a new PC Win7 64bit system?

How do you clean install CS6 on a new PC Win7 64bit system?
I think I've upgraded all th way from Version 7.

There is no problem. If no previous, activated software is detected on the system, the upgrade installer will simply revert to its secondary mode and request to input the old serial in a second step for verification. Unless you do some exotic crossgrade/ sidegrade stuff, this should work with no problems whatsoever.

My 2006 MBP 15" has now been erased. How do I install the system again

Because I was having problems with my 2006 MBP 15 " - sudden freezing up, I tried several ways of fixing it all without success.
Eventually, I was forced into erasing the 500 GB harddrive completely using DU from the install disks (Tiger) that came with it
and had hoped I could re-install the system afresh from the original disks.
On start up all I get is the "Welcome page" again and it repeats itself continually. If i select any thing the spinning beach ball
occurs and a forced shutdown is required.
Everytime I do an install, I get to a "welcome page" and go thru the usual entering of details etc. but every time after I get to
clicking on "continue", when setting up ownership/address, I get a spinning beachball and can get no further.
This continually repeats itself and If i select any thing the spinning beach ball occurs and a forced shutdown is required.
I've tried starting up from an external drive with a firewire cable, but again nothing constructive happens, but I do get a popup saying
it can't find my "home folder as its not in the right place or its missing completely"
Using DU I have tried to do a restore but some how I'm unable to select either the source or the destination - its either all
or nothing available in the side bar of DU.
It seems to me that whatever I do on the MBP I get the spinning ball and no further - even leaving it for a couple of hours -
and still spinning.
Can anyone suggest ways of doing an install, please.
Does it look terminalto you?

The external drive is a bootable one done with SuperDuper.
I am able to do a startup with it but then I get that window saying home folder is missing etc.
Surely i should be able to install the Op/System using the original disks that came with it, or will they only work if there is something on the H/D to start with. I completely erased it to start withj.
I've just found an Install disk for Tiger I bought in 2006 - perhaps that might work or not.

Hello i have a problem with my MacBook Air they wiped out the operating system then installed windows 7 how do i re install the apple firmware

Hello i have a problem with my MacBook Air they wiped out the operating system then installed windows 7 how do i re install the apple firmware please help

That is incorrect. You can install Windows on a Mac, any Mac, without having OS X installed on it.
To the OP you will need the original system reinstall USB thumb drive that came with your Mac Air if it is older than a Mid 2011 model or if it is newer than a Mid 2011 model you use the Online Internet recovery system.
If you don't have that original reinstall USB thumb drive you can order one from Apple for a small charge. Call Apple and ask to speak to someone Specifically to order a Replacement USB system reinstall thumb drive for your model year. You will need the serial number of that Air. It is etched into the bottom of the case.

You can't run Windows on your Macbook Air without having Mac OS X installed with Boot Camp. So it should be an option to select the Mac OS X partition at startup when holding down the option key. Take a look at this link, http://support.apple.com/kb/HT4818

This problem has me put my head in the water and I can not solve: I have done as said already put the trash preferences but nothing worked, still crashes.

My newest iMac from a year ago is showing signs of slowing down its processing capability. Notice it especially in Aperture where I get the whirling dervish thing sometimes for a minute or more and once it crashed. Is there a way to "clean up the system"?

My newest iMac from a year ago is getting very sluggish. I notice it particularly in Aperture. I get the whirling dervish thing going on an operation sometimes for many seconds, even a minute or more and once it just crashed and I had to restart with the button. So I'm wondering if there is some way to "clean up the system" that is built into the iMac or if there is a reliable app I can obtain that will clean things up. I'm supposed to have a super fast processor in this version of iMac and lots of hard drive space and RAM. What gives? Any suggestions?

Things You Can Do To Resolve Slow Downs
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.

How do I re-install the OS if I can't get past the user login screen?

Hi. I recently was given a Mac mini. Great right? Problem is, it's used and it has two users with password protection and there us no way to get in touch with those people to get their passwords and log in.
I thought I would just try putting in the OS X install disk and re-install the system and start fresh. I tried holding down the C key while starting up the computer. It still goes to the log in screen. Does that sound right? I tried that a few times, tried starting up in safe mode... every time it just goes to the log in screen. How do I get passed this? Are there any other ways to wipe the hard drive clean and do a clean re-install of the OS and not have to deal with the log in screen???

As long as you have the original OS X disks, follow directions here,about half way down the note, to change the admin password: http://support.apple.com/kb/HT1274

How can I re-install the last version of iPhoto, I hate this new version.

How can I re-install the last version of iPhoto. I hate this new version "Photos 1.0" which installed yesterday on my iMac. Please help. My operating system is OS X YOSEMITE 10.10.3. THANKS.

Go to the App Store and check out the Purchases List. If iPhoto is there then it will be v9.6.1
If it is there, then drag your existing iPhoto app (not the library, just the app) to the trash
Install the App from the App Store.
Sometimes iPhoto is not visible on the Purchases List. it may be hidden. See this article for details on how to unhide it.
http://support.apple.com/kb/HT4928
One question often asked: Will I lose my Photos if I reinstall?
iPhoto the application and the iPhoto Library are two different parts of the iPhoto programme. So, reinstalling the app should not affect the Library. BUT you should always have a back up before doing this kind of work. Always.

I have hp 430 laptop,how can i re install the windows 7, if i not have original windows on my laptop. i have oem number,
But i have troubol to finishing installation of window.

Originally the Notebook will have the Recovery Partition and that would give you an option to create a set of Recovery Disk. If you have not created those Recovery Disks when the Notebook was in working condition we cannot do that right now
As of now if you need to recover your Notebook with the new Operating System you can check if the Recovery Partition is in a working condition or not, If yes you can easily recover/restore your Notebook
If Recovery Partition is corrupted
You need to call HP Technical Support and request for a set of Recovery Disks , So you can recover/restore your Notebook at the earliest
OR
You need call up Microsoft and purchase an Operating System with the License Key, So you can recover/restore your Notebook at the earliest
I strongly recommend you to Contact HP Technical Support over the Phone for further assistance without any delay
Hope this helps, for any further queries reply to the post and feel free to join us again

Clean up the system

I have been using Archlinux for almost a year now. I started to notice that my root filesystem size has been increasing. It now stays at 6GB. I wanted to know if there are any ways of cleaning up the system of leftover files.
I asked in irc and read in newsletter about pacman -Qdt and removed all orphan files. I still cant believe 6GB has been filled. Is it possible for pacman to list the packages in the order of decreasing size?
Have anybody faced a problem like this ? What should be the approach to cleanup the sytem?

sense wrote:That cleaned up 300MB. It seems I have installed a *lot* of packages. Can pacman output the packages in the order of decreasing size?
pacman can't, but there are many ways to do it. A simple script using pacman, or using directly /var/lib/pacman, or a tool using libalpm.

Do a backup before doing anything.
If you want to make a clean install of Yosemite boot into the Recovery Volume (command - R) on a restart, use Disk Utility to Verify/Repair the disk and run Repair Permissions. Then erase the hard drive using Mac OS Extended (Journaled) format using the Options button. Reinstall Yosemite. Restart normally and test. Use Setup Assistant or Migration Assistant to import what you want.

I would download the installer and you can make a bootable USB stick to install using this free program. You can then install from there.
