Replace the Glossy Screen with the Matte Screen on a 2008 Macbook Pro?

Can you replace the Glossy Screen with the Matte Screen on a 2008 Macbook Pro?
Where would I get a Matte Screen for a reasonable price if I could change it?

There are a number of issues you should consider before embarking on this project.
1. If you have a late-2008 unibody MBP, you are undoubtedly aware that there was never any anti-glare option offered for that machine. So there is no anti-glare display that was made to work with it.
2. If you choose to replace only the LCD panel and not the entire display assembly — which is probably feasible but involves a great deal of painstaking work — you will also need to buy (separately) the aluminum bezel that takes the place of the glossy cover glass panel in models that came equipped with the nonglare screen. The bezel covers and protects the edges of the LCD and the delicate electronic connections there, and hides all that from view.
3. If you go that route, you will have to make sure that the cabling related to the display you are installing is identical to the cabling related to your original display. This means checking to make sure the cable lengths, connectors and routing both within the display assembly and hinge cover and within the lower case of the computer are all the same.
4. If you choose to replace the entire display assembly with one that contains a nonglare LCD, you will have the entire, intact glossy display assembly available to sell afterward. If you replace only the LCD panel, the LCD and glass cover panel that you remove will have much less resale value and are likely to be much harder to sell at all, because you won't practically be able to offer any warranty with them and because there are probably far fewer people willing to tackle the fussy, risky display disassembly process than are willing to replace the whole assembly as a unit.
5. Even if you choose to replace the entire assembly, you will need to verify that the cables dangling from the replacement display assembly are the right lengths and have the right connectors to tie into your lower case properly. Because the assembly will have come from a later MBP model than yours, cable routing and connectors may have changed from one to the other.
If this all sounds more daunting than you were expecting, you may want to consider just applying a nonglare film to the glass covering your present screen. If you aren't happy with the results, you can fall back on the replacement option.

What version of LR should I choose to run it on a 2008 macbook pro OS 10.5 (updated with 8GB RAM)

As it says in the title: I want to run LR on my 2008 macbook pro OS 10.5 (updated with 8GB RAM). Adobe support told me that it would not be a problem, yet i'm confronted with a com.apple.installer.pagecontroller error -1. I have no idea what it is or how to solve it.
Can you please help me? Thank you.

You will not be able to use a LR 5 key on an older LR. While an intermediate version of OS X may be easier on your system and may allow a newer version of LR than LR3, if it is not current you still have to get that old version of LR from an alternate channel.
If you have an easy way to clone your system I would try upgrade you Yosemite and putting LR 5 on it since you have a key. If it doesn't perform to your satisfaction you can always clone back to 10.5 and seek an alternate solution.
However, was the LR 5 key owned by your previous job along with that other laptop? If so, it violates the license for you to use it.

As I can understand you want to make some of the screen field to disable or visible on screen depending upon the interaction of user with screen 1.
You may use this example code in PBO of screen 2.

I just finished downloading and attempting the install of ios 7 on my iPhone 5. I'm using the newest version of iTunes. And now, I'm stuck at the screen with the iTunes logo and the plug. But no matter what recovery mode wont work

I just finished downloading and attempting the install of ios 7 on my iPhone 5. I'm using the newest version of iTunes.
And now, I'm stuck at the screen with the iTunes logo and the plug. But no matter how many times I try, recovery mode will not work. My phone is currently useless unless I can figure this out.

No problem, glad to help!
Update: my PC USB hub was connected to a USB 3 port, I connected the 30 pin cable directly to my PC, And the restore worked just fine. Restored phone from iCloud backup and seems to be working fine.

Refurbished iPod touch 3rd gen won't start. Just got it today to replace my broken one. It freezes at the screen with the apple logo, then flashes off and tries to restart again. Help!

I have tried holding the power home button but all that does is turn it off. When I try to start it again it goes into the same loop.

I have a late 2008 Macbook Pro last updated to Mavericks OS. The screen died and it's not worth replacing. How do I remove the hard drive and use a drive sled to access info I need?

I have a late 2008 Macbook Pro last updated to the Mavericks OS. The screen died and I took it into an Apple store and was told replacing the screen and the hardware to repair everything would cost almost as much as buying a new laptop or a cheaper model. I was told that I can use a drive sled to access data I need on my hard drive. How do I remove my hard drive and use a drive sled to get to the information I need? What makes matters more complicated is I need to update my iPhone and my iTunes/App store purchases. How can I accomplish this?
My wife has a late 2008 Macbook Pro as well, which I am assuming I need to run my hard drive. Is there a way to just access just my hard drive without interfering with hers?
I know this is lengthy. Thanks to whoever looks at this and offers advice/instruction.

the device you need is an External enclosure for a 2.5" (laptop form factor) SATA drive.
A USB-interface enclosure will be slow, but is adequate for this task and for re-purposing as a backup drive later. A firewire-interface drive would be faster, but is harder to find, more expensive, and faster than needed for this purpose.
The drive will mount as an "extra" drive on your wife's Macbook, and you can drag and drop whatever you wish. You could create a separate Account for yourself on her computer, and use Migration Assistant or just copy your stuff over to the new account. Then it would not interfere with her files.

Tecra M2 - black screen with the cursor flashing

Hi guys,
Im hoping someone out there may be able to help me fix my laptop.
Ive read a couple of posts but not sure they can help me.
When I swicth on my Tecra M2, I just end up with a black screen with the cursor flashing in the top left or I get a screen filled with alternating 0's and 1's.
Sometimes the TOSHIBA splash screen appears with the boot options, other times it doesnt.
I cannot boot to CD and it wont boot to the HDD. Ive taken the HDD out and the CDROM out but it does the same thing which to me suggests that its not getting through the BIOS even as far as the boot sequence.
Does this sound like BIOS failure to you and do you know of a way to fix it? Ive tried taking the battery out, powering off and starting again but the same thing happens.
Any advice would be be appreicated.
Thanks,
Ross

I have had this twice now and in both cases it was caused by a faulty HDD - to confirm that the motherboard etc is still OK load the recovery CD in the DVD drive (or even better a freestanding XP disc), press F2 on startup and shift the cursor under the DVD drive as the boot drive.
If the motherboard etc is OK you will get the reload instructions (from the recovery disc) or a Windows install screens (from the XP install disc).
Satisfied that the machine at least works - replace the HDD and recover from the recovery disc or try a Windows repair from the recovery console (from the XP install disc with the HDD still in place).
In my cases I was forced to recover to a new HDD and then rebuild the machine from backups - I now clone the HDD when rebuilt.

My ipad 2 turnes to black screen with the apple icon in the middle, it just hanged and i have to restart it?! so why this is happening ?! is there is an error or something i can do to prevent doing this ?!

my new ipad 2 turnes to black screen with the apple icon in the middle while using it or if i just left it locked for a while, it just hanged and i have to restart it?! so why this is happening ?! is there is a productio error or something i can do to prevent doing this ?!
Appreciate responding as soon as possible.

No, it's definitely not normal. Your User's Guide recommends a series of troubleshooting steps to go through when your iPad is misbehaving: As you're already in effect doing the first of the main steps, a Restart of your iPad, and that's not curing it, move on to the next .. a Reset.
To do this, press and hold both the Home and the Sleep/Wake buttons for about 10-12 seconds, until the display blanks and the red Power Off slider appears. Continue holding the buttons until the slider disappears, replaced by the black screen and white Apple logo.
This shows your iPad is starting to reboot. Release the buttons and allow the process to continue until the Lock screen appears again, then slide the slider to complete the process.

After using my iPod classic in my infinity G35 a few weeks ago, I took it out of the car and it no longer works. Just a white screen with the web address for Apple iPod support. Worked fine when hooked up to iPod jack in car. But wont work anywhere now

After using my iPod classic in my infinity G35 a for the last few weeks, I took it out of the car and it no longer works. Just a white screen with the web address for Apple iPod support. Worked fine when hooked up to iPod jack in car. But won't work anywhere now. I tried re-setting but has not worked. Any ideas would be appreciated.

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!!

I have a 4th generation iPod nano 4th and when I turn it on, the screen won't progress passed the main screen with the Apple logo. What should I do?

I have a 4th generation 8GB iPod nano and it will not progress past the blank screen with the white apple logo on it. I have charged it fully and tried to restart it by pressing and holding the menu buttons for 3-7 seconds. The devices screen will turn off and then, after a couple of seconds, the screen with the Apple logo will appear again. This screen will remain lit until the iPod runs out of battery again. I have tried plugging it into my Macbook Pro. I have the newest versions of iTunes software and OS X Mavericks. The computer will not recognize the iPod and the device will not show up in the computers list of devices. I looked up the troubleshooting for the device and found out how to put the device into disk mode. I followed the intructions but the iPod would not go into disk mode. The screen still displayed the Apple logo and would not set into disk mode. I fear that I have run out of options. I have come to this forum in hopes that I can still salvage my device. If there is anything I can do, please loet me know so I can try it. If not, I am affraid I will have to go to an Apple store of authorized retailer and have it repaired or replaced.

Try manually connecting the device to your PC in Disk Mode and then restoring it iTunes.
From http://support.apple.com/kb/HT1363
Putting iPod devices with a Click Wheel into Disk Mode
If necessary, verify that your iPod has a Click Wheel.
Before placing the iPod into Disk Mode, verify that it is charged.
Toggle the Hold switch on and off (set it to Hold, then turn it off again.)
Press and hold the Menu and Select buttons for at least six seconds, until the Apple logo appears.
When the Apple logo appears, release the Menu and Select buttons and immediately press and hold the Select and the Play/Pause buttons until the Disk Mode screen appears.
Connect the iPod to your computer; the screen on the iPod will should say "Do not disconnect".
If you are having difficulty putting your iPod into Disk Mode, set it on a flat surface. Make sure that the finger pressing the Select button is not touching the Click Wheel. Also make sure that you are pressing the Play/Pause button toward the outside of the Click Wheel and not near the center. If you are still unable to put your iPod into Disk Mode, use one finger from one hand to press the Select button, and one finger from the other hand to press the Play/Pause button.

My 2011 IMac will not boot up past the White apple logo screen with the whirly circle

My 2011 IMac will not boot up past the White apple logo screen with the whirly circle. I have tried various commands but to no avail. does anybody have any advice?

Take each of these steps that you haven't already tried. Stop when the problem is resolved.
Step 1
The first step in dealing with a startup failure is to secure the data. If you want to preserve the contents of the startup drive, and you don't already have at least one current backup, you must try to back up now, before you do anything else. It may or may not be possible. If you don't care about the data that has changed since the last backup, you can skip this step.
There are several ways to back up a Mac that is unable to start. You need an external hard drive to hold the backup data.
a. Start up from the Recovery partition, or from a local Time Machine backup volume (option key at startup.) When the OS X Utilities screen appears, launch Disk Utility and follow the instructions in this support article, under “Instructions for backing up to an external hard disk via Disk Utility.” The article refers to starting up from a DVD, but the procedure in Recovery mode is the same. You don't need a DVD if you're running OS X 10.7 or later.
b. If Step 1a fails because of disk errors, and no other Mac is available, then you may be able to salvage some of your files by copying them in the Finder. If you already have an external drive with OS X installed, start up from it. Otherwise, if you have Internet access, follow the instructions on this page to prepare the external drive and install OS X on it. You'll use the Recovery installer, rather than downloading it from the App Store.
c. If you have access to a working Mac, and both it and the non-working Mac have FireWire or Thunderbolt ports, start the non-working Mac in target disk mode. Use the working Mac to copy the data to another drive. This technique won't work with USB, Ethernet, Wi-Fi, or Bluetooth.
d. If the internal drive of the non-working Mac is user-replaceable, remove it and mount it in an external enclosure or drive dock. Use another Mac to copy the data.
Step 2
If the startup process stops at a blank gray screen with no Apple logo or spinning "daisy wheel," then the startup volume may be full. If you had previously seen warnings of low disk space, this is almost certainly the case. You might be able to start up in safe mode even though you can't start up normally. Otherwise, start up from an external drive, or else use the technique in Step 1b, 1c, or 1d to mount the internal drive and delete some files. According to Apple documentation, you need at least 9 GB of available space on the startup volume (as shown in the Finder Info window) for normal operation.
Step 3
Sometimes a startup failure can be resolved by resetting the NVRAM.
Step 4
If you use a wireless keyboard, trackpad, or mouse, replace or recharge the batteries. The battery level shown in the Bluetooth menu item may not be accurate.
Step 5
If there's a built-in optical drive, a disc may be stuck in it. Follow these instructions to eject it.
Step 6
Press and hold the power button until the power shuts off. Disconnect all wired peripherals except those needed to start up, and remove all aftermarket expansion cards. Use a different keyboard and/or mouse, if those devices are wired. If you can start up now, one of the devices you disconnected, or a combination of them, is causing the problem. Finding out which one is a process of elimination.
Step 7
If you've started from an external storage device, make sure that the internal startup volume is selected in the Startup Disk pane of System Preferences.
Start up in safe mode. Note: If FileVault is enabled, or if a firmware password is set, or if the startup volume is a Fusion Drive or a software RAID, you can’t do this. Post for further instructions.
Safe mode is much slower to start and run than normal, and some things won’t work at all, including wireless networking on certain Macs.
The login screen appears even if you usually log in automatically. You must know the login password in order to log in. If you’ve forgotten the password, you will need to reset it before you begin.
When you start up in safe mode, it's normal to see a dark gray progress bar on a light gray background. If the progress bar gets stuck for more than a few minutes, or if the system shuts down automatically while the progress bar is displayed, the startup volume is corrupt and the drive is probably malfunctioning. In that case, go to Step 11. If you ever have another problem with the drive, replace it immediately.
If you can start and log in in safe mode, empty the Trash, and then open the Finder Info window on the startup volume ("Macintosh HD," unless you gave it a different name.) Check that you have at least 9 GB of available space, as shown in the window. If you don't, copy as many files as necessary to another volume (not another folder on the same volume) and delete the originals. Deletion isn't complete until you empty the Trash again. Do this until the available space is more than 9 GB. Then restart as usual (i.e., not in safe mode.)
If the startup process hangs again, the problem is likely caused by a third-party system modification that you installed. Post for further instructions.
Step 8
Launch Disk Utility in Recovery mode (see Step 1.) Select the startup volume, then run Repair Disk. If any problems are found, repeat until clear. If Disk Utility reports that the volume can't be repaired, the drive has malfunctioned and should be replaced. You might choose to tolerate one such malfunction in the life of the drive. In that case, erase the volume and restore from a backup. If the same thing ever happens again, replace the drive immediately.
This is one of the rare situations in which you should also run Repair Permissions, ignoring the false warnings it may produce. Look for the line "Permissions repair complete" at the end of the output. Then restart as usual.
Step 9
If the startup device is an aftermarket SSD, it may need a firmware update and/or a forced "garbage collection." Instructions for doing this with a Crucial-branded SSD were posted here. Some of those instructions may apply to other brands of SSD, but you should check with the vendor's tech support.
Step 10
Reinstall the OS. If the Mac was upgraded from an older version of OS X, you’ll need the Apple ID and password you used to upgrade.
Step 11
Do as in Step 9, but this time erase the startup volume in Disk Utility before installing. The system should automatically restart into the Setup Assistant. Follow the prompts to transfer the data from a Time Machine or other backup.
Step 12
This step applies only to models that have a logic-board ("PRAM") battery: all Mac Pro's and some others (not current models.) Both desktop and portable Macs used to have such a battery. The logic-board battery, if there is one, is separate from the main battery of a portable. A dead logic-board battery can cause a startup failure. Typically the failure will be preceded by loss of the settings for the startup disk and system clock. See the user manual for replacement instructions. You may have to take the machine to a service provider to have the battery replaced.
Step 13
If you get this far, you're probably dealing with a hardware fault. Make a "Genius" appointment at an Apple Store, or go to another authorized service provider.

My 06' Macbook Pro crashed with vertical, green pixelated lines and now will not advance past the turn-on screen with the apple filled with green lines as well. Then, it says to hold down the power button to restart. Help?

My 06' Macbook Pro crashed with vertical, green pixelated lines and now will not advance past the turn-on screen with the apple filled with green lines as well. Then, it says to hold down the power button to restart. I have tried several times to get it past this point but tnothing helped.
I have an appointment at the Apple store today, but was wondering : will all of the information and files on my desktop be lost? Or is this a logic board problem?
Any help is much MUCH appricated.

I'm not sure, if you're out of warrenty it'll cost quite a bit for the replacement of the logic board replacement...unless you have apple care. you could ask apple to try and recover your hard drive but i'm not sure.

HT4623 I downloaded ios7 and initially it was working fine. Now it is flashing from my home screen to the white screen with the black apple every 3-5 seconds. It's so annoying and I can't make it stop! I tried shutting down all the way - nope! HELP!

I downloaded ios7 on my iphone 5 yesterday. All day it worked fine, then last evening it started blinking from the white screen with the black apple to my home screen. Each screen only stays up for 3-5 seconds then switches back. I have tried shutting down and it is still happening! Does anyone know how to fix this issue without having to go into the store?

Your power adapter is OK. If the only place it will not work is in your home, your house wiring and / or the appliances connected to it are likely to be the reason your Mac will not charge.
From Troubleshooting MagSafe adapters:
Identify line noise issues.
Unplug the power adapter from the wall, let it sit for 60 seconds, then plug the adapter back in.
If the adapter works after this 60-second "rest", you most likely have a line noise issue with your power source. You should reset the adapter periodically by repeating this moment of rest. This issue occurs when the AC adapter's "over voltage protection" feature senses ground noise and then turns off the adapter.
Some possible sources of line noise include lights with ballasts, refrigerators, or mini-refrigerators that are on the same electrical circuit as your computer. This behavior may not occur if you plug the power adapter into an uninterruptible power supply (UPS) or plug it into a different circuit.
Unless the adapter continues to exhibit this behavior on a known good outlet, it does not need to be replaced.
Household wiring problems are very common. They can also be very dangerous. Fortunately most problems can be easily fixed by a qualified electrician.

I am not able to use my Mac while FileVault is encrypting. Is it frozen on a gray screen with the apple logo. Is it actually encrypting?

I have an early 2008 MacBook and running iOS Lion. I just turned on FileVault and restarted my computer as instructed. It told me before hand that I would still be able to use my Mac while the files were being encrypted. However, when I logged in on the secure gray login screen, I was only directed to a plain gray screen with the apple logo in the center. There are no time turners or anything moving. Is my Mac encrypting or is it frozen in some sort of way? If it is encrypting, how long does it usually take? and if it is frozen, how do I unfreeze it?

Launch Disk Utility in Recovery mode (see Step 1.) Select the startup volume, then run Repair Disk. If any problems are found, repeat until clear. If Disk Utility reports that the volume can't be repaired, the drive has malfunctioned and should be replaced. You might choose to tolerate one such malfunction in the life of the drive. In that case, erase the volume and restore from a backup. If the same thing ever happens again, replace the drive immediately.
This is one of the rare situations in which you should also run Repair Permissions, ignoring the false warnings it may produce. Look for the line "Permissions repair complete" at the end of the output. Then restart as usual.
Step 9
If the startup device is an aftermarket SSD, it may need a firmware update and/or a forced "garbage collection." Instructions for doing this with a Crucial-branded SSD were posted here. Some of those instructions may apply to other brands of SSD, but you should check with the vendor's tech support.
Step 10
Reinstall the OS. If the Mac was upgraded from an older version of OS X, you’ll need the Apple ID and password you used to upgrade.
Step 11
Do as in Step 9, but this time erase the startup volume in Disk Utility before installing. The system should automatically restart into the Setup Assistant. Follow the prompts to transfer the data from a Time Machine or other backup.
Step 12
This step applies only to models that have a logic-board ("PRAM") battery: all Mac Pro's and some others (not current models.) Both desktop and portable Macs used to have such a battery. The logic-board battery, if there is one, is separate from the main battery of a portable. A dead logic-board battery can cause a startup failure. Typically the failure will be preceded by loss of the settings for the startup disk and system clock. See the user manual for replacement instructions. You may have to take the machine to a service provider to have the battery replaced.
Step 13
If you get this far, you're probably dealing with a hardware fault. Make a "Genius" appointment at an Apple Store, or go to another authorized service provider.
