Half screen goes dark on macbook 2.13 ghz intel core 2 duo

Hi everybody...I am having problems with the screen on my MacBook Laptop. Half the screen has greyed out (the bottom half). All of a sudden using the MacBook, the half the screen goes grey, perfectly in horizontal. I´ve been with Apple 21 yrs, I have zapped the PRAM, taken out Ram, put it back in, repaired permissions, passed it thru Disk Warrior. I am out of solutions...Has anybody experienced these problems?
What were your symptoms? Thank you so much to all the good people out there.

Let's find out for sure if this is a hardware issue. Boot the MacBook holding down the option key to get to the startup manager. Is the problem present here?
If so your MacBook has a hardware problem. Contact Apple using expresslane.apple.com if you are in a country that supports it or call the appropriate phone number on this page. Alternatively carry the MacBook in to an Apple retail store or service provider to ask for an estimate.
Best of luck.

Adding Memory to a White MacBook 2.16 Ghz Intel Core Duo (Memory 1Gb 667 Mhz DDR2 SDRAM)

Good afternoon from London.
I want to put 2x2GB memory into my MacBook (mid 2007) but Apple support site specifies that the maximum amount of memory for this model is 2Gb. In other words, I can only add 2X1Gb.
What would happen if I proceed?

Thanks. They say the following, which I take to mean that I am good to go:
MacBook2,1 (All) - Install up to 4.0GB total memory, uses up to 3.0GB.
Note: Although limited to physically utilizing a maximum of 3GB, there is a performance
benefit due to 128 Bit addressing when 4GB( 2GB x 2 Matched set) is installed.

Old macbook pro3,1 (2.4 GHz Intel Core Duo) camera not working with Mavericks

I have an old macbook pro3,1 (2.4 GHz Intel Core Duo, I think 2007), builtin camera not working and I think it is related to mavericks update.
Anyone had the same problem, and if yes what is the solusion?

Try these in order testing your system after each to see if it's back to normal:
1. a. Resetting your Mac's PRAM and NVRAM
    b. Intel-based Macs: Resetting the System Management Controller (SMC)
2. Restart the computer in Safe Mode, then restart again, normally. If this doesn't help, then:
     Boot to the Recovery HD: Restart the computer and after the chime press and hold down the
     COMMAND and R keys until the Utilities 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 and click on the downward pointing arrow button.
3. Repair the Hard Drive and Permissions: Upon startup select Disk Utility from the Utilities menu. Repair the Hard Drive and Permissions as follows.
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 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.
     Reinstall the 10.9.2 update: OS X Mavericks 10.9.2 Update (Combo).
4. Reinstall Lion/Mountain Lion, Mavericks: Reboot from the Recovery HD. Select Reinstall Lion/Mountain Lion, Mavericks from the Utilities menu, and click on the Continue button.
Note: You will need an active Internet connection. I suggest using Ethernet if possible because it is three times faster than wireless.
Reinstall the 10.9.2 update: OS X Mavericks 10.9.2 Update (Combo).

My Mac has a 2.16 GHz Intel Core Duo, is it going to be compatible with Lion?

Anything I can do, Niel?
Enjoy it and by the time your machine finally kicks the bucket there will be three more cats gone by.
Likely there won't be any keyboards, trackpads, cd/dvd or hard drives or even screens.
They will just stick a Mac-borg implant in your head and you wave your fingers around in the air to access data.
Think of all the money you'll save in between!

I have Microsoft Office 2004 on my MacBook (2.4 GHz Intel Core 2 Duo). It is currently up to date with Microsoft updates. I am running Mac OS 10.6.8. I just updated my Mac software with "Security Update 2012-001". I am now unable to print (Epson NX510

I have Microsoft Office 2004 on my MacBook (2.4 GHz Intel Core 2 Duo). It is currently up to date with Microsoft updates. I am running Mac OS 10.6.8. I just updated my Mac software with "Security Update 2012-001". I am now unable to print (Epson NX510 printer) from Excel or Word. When I click on the Print menu item in Excel, there is a flash in the background like it is trying to open the print window, but nothing else. I am able to print from other programs like TextEdit, Mail or KakeidaGraph. As far as I know I have the latest Epson print driver.
Also, I am also unable to open an existing Excel or Word file from the open menu - both programs lock up and do not respond. I have to force quit. After I restart Excel or Word I can open an existing file by double clicking on the file, but if I again try to open another file from the open menu, Excel or Word lock up.
Any similar problems?

Howdy,
Apparently some are reporting that this causes the older PowerPC (PPC) applications that are supported in 10.6 via 'Rosetta' to crash upon attempting to open/save/print using any dialog box, or fail in other similar ways such as simply not printing or quitting, or freezing/hanging/crashing of the application.
I have read of some companies that have indeed submitted proper bug reports to Apple, but that is not a guarantee of a bug-fix being issued.
You might wish to read:
http://www.macintouch.com/readerreports/snowleopard/index.html#d02feb2012
If you are unsure if you are still using PowerPC apps, if the application is currently running, look under the 'Activity Monitior' (in Applications -> Utilities), or alternatively you could check in the System Profiler, Applications. Check the column "Type".
Here is a fairly simple way you can restore you system and restore you applications functionality again, if you don't have a recent clone or good Time Machine backup that you can restore from. If you do, restore from your backup prior to having installed the Security Update 2012-001.
Time Machine restore: http://support.apple.com/kb/ht1427
If you are restoring a backup made by a Mac to the same Mac
With your backup drive connected, start up your Mac from the Lion recovery partition (Command-R at startup) or Mac OS X v10.6 installation disc. Then use the "Restore From Time Machine Backup" utility. Select the backup prior to your issues, and it will be restored back to the state it was in at that time.
If you can't easily restore from a backup, you can instead do the following:
- You first start by reinstalling your OS X 10.6.x, this will preserve all your user data, your applications, no worries there.
- Then install the Mac OS X 10.6.8 Update Combo v1.1 (links provided below)
- Make sure you're printers are showing up correctly in your system preferences, if not, re-add the printers
- Then finally, run the Apple Software Update (by pulling down the Apple Menu), and install any and all remaining updates, except do not then re-install the Security Update 2012-001. It is possible that you may have to reboot after installing some of the updates, and you may even need to run it a 2nd time to make sure that you've got all updates, except NOT the Security Update 2012-001.

Macbook Pro with 2.16 GHz Intel Core Duo Windows install advice

I find myself after 20 years using mac's needing to run a windows program. I have Macbook pro 2.16GHz Intel Core Duo and was wondering if anyone can tell me if parallels or fusion works better on this machiene. Also i see some folks here feel Windows 7 is the way to go. Any advice would be appreciated.
tks in advance for any advice
-R-

A lot of the answer really depends upon you and your usage.
VMWare Fusion, and Parallels Desktop both work well, nad each ahs its strengths and weaknesses. I have used Fusion v3, 4, & 5, as well as Parlallels v 3, 4, 5, 6, 7, & 8. I got my first copy of Parallels when I got my first MacBook Pro as a bundle deal along with a Windows XP Pro license. For my usage, I find that Parallels seems to be more "efficient" (it runs a little faster) but Fusion seems to be a bit more stable, and supports a slightly broader collection of hardware peripherals. Luckily for you, both packages offer a free trial before you buy the software, so you can test them both to see which works best for you. You could also consider using VirtualBox (a free tool much like Fusion or Parallels), or even Boot Camp if you need the "raw power" of running the system in native mode with no emulation overhead.
As for What version of Windows you run, it would really depend upon what licenses you have, and what your Windows software requires. some Windows software still requires Windows XP, some requires Windows 7 or later. Since you didn't mention your Windows app, I can't say for it.
In the end, it depends upon you, what you want, what you need, and what you are willing to pay for.

Will my Macbook 13" late 2006 take the RAM from a Macbook Pro 13" 2.4 Ghz Intel Core Duo?

I have a macbook 13" late 2006 and i found it was cheaper to buy a 13" Macbook Pro 2.4 Ghz Intel Core Duo Ram, I was just wondering if the ram out of the pro model will fit my older model?

Some basic guesses from http://www.everymac.com
MacBook 13" Late 2006 is a MacBook2,1 and that uses PC2-5300 DDR2 667 MHz ram.
MacBook Pro 13" did not use 2.4 GHz but the first of the 13" models was the MacBook Pro7,1 and that uses PC3-8500 DDR3 1066 MHz ram.
Those are not compatible and cannot be used interchangeably.

Is it possible to upgrade a macbook 2.16 ghz intel core 2 duo to OSX 10.8.5?

I have an old mackbook, approx 2007 era. Is it possible to upgrade a macbook 2.16 ghz intel core 2 duo to OSX 10.8.5?

You can only upgrade to 10.7 Lion. Lion is still available from Apple. You will have to call Apple Customer Care 1-800-692-7753 or 1-800-676-2775. to purchase it. Then within 3 days you will get an email with a code which you can use to download Lion from the App Store. Or go to http://store.apple.com/us/product/D6106Z/A/os-x-lion and purchase it there. The price is $19.99.
You will have to be at 10.6.8 first.
The 10.6 Snow Leopard DVD is in the Apple online store. You can get it for $19.99. After you’ve installed that then use the 10.6.8 combo updater to finish it off. http://support.apple.com/kb/DL1399 You will need to be running 10.6.8 to access the App Store to order Lion. http://store.apple.com/us/product/MC573/mac-os-x-106-snow-leopard
System Requirements for 10.6:
Mac computer with an Intel processor
1GB of memory
5GB of available disk space
DVD drive for installation
Some features require a compatible internet service provider: fees may apply.
Lion will require at least 2gb of RAM but really needs 4gb to run smoothly.
As for third party programs see this list for compatibility with 10.7 http://roaringapps.com/apps:table
Also Lion doesn't run any Power PC programs. To see if you have any Power PC programs go to the Apple in the upper left corner and select About This Mac, then click on More Info. When System Profiler comes up select Applications under Software. Then look under Kind to see if any of your applications are listed as Power PC. Universal and Intel will run under Lion.
Before Mac switched to Intel processors in 2006 they used Power PC processors from 1994 to 2005. Power PC 601 through 604, G3, G4 and G5. Applications written for the Power PC processors need the application called Rosetta to run on Intel processors. This was part of the Operating System in 10.4 and 10.5 but was an optional install in 10.6. With 10.7 Lion Apple dropped all support for Power PC applications.
You can put two 2gb RAM sticks in your model 2,1 but it can only use 3,3gb. This is a hardware limitation and cannot be changed.
http://en.wikipedia.org/wiki/3_GB_barrier
http://www.everymac.com/systems/apple/macbook_pro/faq/macbook-pro-core-2-duo-3-g b-memory-limitation-details.html
OWC tests have found that there is a slight speed increase with having two 2gb sticks in rather than one 1gb and one 2gb. Your model is in the gray lines at the bottom of the graph. http://eshop.macsales.com/shop/Memory_Benchmark/Apple_MacBook/

I have a macbook pro with a 2.16 GHz Intel core Duo processor. Can I install the iOS 5 software

I have a macbook pro with a 2.16 Ghz Intel core Duo processor. Can I install the iOS 5 software?

iOS 5 is for iDevices, not OS X. Your iDevice would only require 10.5.8 or later. If you have a Mac with a Core Duo processor then you cannot install Lion but you can install Snow Leopard provided you have at least 1 GB of RAM installed.

Is installation on 2.16 GHz Intel Core Duo (MacBook Pro)really not possible and why?

I would like to buy OS X Lion and install it on my MacBook Pro with 2.16 GHz Intel Core Duo, but this processor is not in the list of the specifications (Mac computer with an Intel Core 2 Duo, Core i3, Core i5, Core i7 or Xeon processor).
Is it really true that I can't install Lion on my Mac? If so, what is the reason?

It has to be a Core 2 Duo. Those are the requirements for Lion.
Requires a newer Mac.
Lion requires an Intel-based Mac with a Core 2 Duo, i3, i5, i7 or Xeon processor and 2GB of RAM.

What is a recommended decompression software for a non-Lion compatible MacBook Pro 1,1 2 GHz Intel Core Duo running OS X Version 10.6.8?

What is a recommended decompression software for a non-Lion compatible MacBook Pro 1,1 2 GHz Intel Core Duo running OS X Version 10.6.8?

My thanks to you and all other respondents. In backing up "theVault" App I thought that my ancient version of Stuffit was inadequate to unzip the backup file. I attempted to download the latest Zipit version which only works with Lion. After upgrading to Stuffit 9 I realized that theVault backup file was encrypted so as to not open on the backup Mac. One must restore to the iPhone where is does open.
My apologies for the imprecise post. I am finding limitations with not being able to install Lion on my early MacBook Pro. I can recommend theVault to those looking for a password App with secure backup.

Since my macbook pro is an intel core duo but not a core 2 duo, I cannot upgrade to Yosemite. So... what OS X can I upgrade to with this computer?

Since my macbook pro is an intel core duo but not a core 2 duo, I cannot upgrade to Yosemite. So... what OS X can I upgrade to with this computer? Thanks for the input.

Intel Core Duo is a 32-bit processor, so the latest Mac OS X version you can install is Mac OS X Snow Leopard -> http://store.apple.com/us/product/MC573Z/A/mac-os-x-106-snow-leopard
You are running Mac OS X 10.6.8, so you are already running the most recent Mac OS X version for your computer.

Whats the lastest software i can put on a macbook 2.2 GHz intel core 2 Duo. the software i have on the laptop right now is the Mac OS X (10.6.7)?

whats the lastest software i can put on a macbook 2.2 GHz intel core 2 Duo. the software i have on the laptop right now is the Mac OS X (10.6.7)?

It would help to know which one of the 9 different models of MacBook you have. To see which model you have go to the Apple in the upper left corner and select About This Mac, then click on More Info. When System Profiler comes up check the Model Identifier and post it back here.
If it's the Late 2007 model 3,1 then 10.7 is the most that it can run.

You need a "Core 2 Duo" for lion, and I'm guessing you only have a "Core Duo" My wife's macbook is also a "Core Duo" and has Snow Leapord, but cannot install Lion.....
