My Mac Book Pro will be 4 years old in Sept. I now have Snow Leopard and bought an IPhone 4S this week. I know I need Lion to use ICloud. Can I upgrade to Lion with a computer this old?

As long as it meets the minimum requirements:
Lion System Requirements
Mac computer with an Intel Core 2 Duo, Core i3, Core i5, Core i7, or Xeon processor
At least 2GB of memory
OS X v10.6.6 or later (v10.6.8 recommended)
7GB of available space on hard drive
Some features require an Apple ID; terms apply.

My mac book pro 17 inch , 2008 year , display went dark, and the steps in "everthing Mac" book did not work, any ideas?

The router might be bad or incompatible, but let's be optimistic.
On System Preferences, go to Network/Advanced/PPP. Only two items should be checked: Connect Automatically When Needed and Disconnect when switching user accounts. Uncheck everything else. Now, click Okay on the end of the page. The next time you're online, you shouldn't be disconnected.
If you still get disconnected like before, we might be dealing with a router issue - which can get rather complicated.

My new mac book pro will not save any bookmarks I make in safari. Why is it doing this? I would really like to use my bookmarks.

MY new Mac book pro will not save any of teh bookmarks I make in safari. If I make a bookmark, it will not appear until I close safari and reopen it. Then, if I shut my computer down and reopen safari, all of the bookmarks are gone. This has happend multiple times and I don't know what is going on. I would really like to use my bookmarks.

Delete the

Downloaded and installed os x yosemite and now mac book pro will not restart? How long should this take? Is there something wrong? Please helpthanks in advance

MAc book pro. I have downloaded and installed os x yosemite now mac book pro will not start? How long should it take? Is there something wrong?

The 2 computers here took about 45 minutes to an hour each.
The best thing to do is give it more time. If it gets too ridiculous, shutdown using the power button and then restart. Check  menu/About This Mac to see if it is installed.

I have had my mac book pro for about a year and a half and suddenly my dvd player will not play DVDs and i can not play alot of things on full screen. Does anybody know how i can fix this?

This could be several things, but let's get the obvious ones out of the way, first:
1. Judging from your text, there's no problem with anything stuck in the mechanism; it's more an issue of no being to put in a disk. In other words, you're sure that there isn't a disk stuck in your MBP. (That happens a lot for all computers.)
2. Go to Applications/Utilities/Disk Utility, and repair the disk. This should take under 10 minutes.
3. Perform the procedure outlined here:

4. After you're done, leave a message here as to the status of the repair.

You could try doing a hard shut down (holding the power button or yanking the battery) and then doing a safe boot by holding the shift key at startup:

Also, not sure if this applies in your case, but I've had that happen when there's a USB drive inserted either in the computer or a connected external keyboard. I did a hard shut down, removed the drive and it went through a normal start up.

My mac book pro will not shot down or restart.

mac book pro 13 2011 dec. mac os x 10.7.4. my mac book pro will not shot down or restart, my mac is to slow to much loading. . when i open some apps loading when i will restart my mac book pro
loading. i can't restart the same problem when i wil shut down my mac. need help

Mackeeper has been known to cause more problems than fix, all the posts here say don't use it and offer instuctions on how to remove it, which is not as easy as just dragging it to the trash.
I am willing to guess that some of the third party software could be the issue.
Try a safe boot:
http://support.apple.com/kb/HT1564
Starting up in “safe mode” may help you diagnose problems you’re having with your Mac.
Note: To print these instructions, open the Help Viewer’s Action pop-up menu (looks like a gear) and choose Print.
Shut down your Mac and wait 10 seconds.
Press the power button.
Immediately after you hear the startup tone, hold down the Shift key.You should press the Shift key as soon as possible after you hear the startup tone, but not before.
Release the Shift key when you see the gray Apple logo and progress indicator (spinning gear).
To leave safe mode, restart the computer normally without holding down any keys during startup.
If you still have problems I would take it to Apple, there seems to be something strange going on here.
You search remove mackeeper on this forum, and get rid of it.

17 inch MAC book pro will not boot up

My 17 inch MAC Book Pro will not power/boot up. The battery is charged and it displays a green light on the power adapter. However, it will not boot up.

Reset the SMC > http://support.apple.com/kb/HT3964
If it doesn't work, probably there's a logic board problem, so it's possible that you need a new logic board. Take your computer to an Apple Store or reseller

My Mac Book Pro will not start up. I ran the AHT and received the following error: 4SNS/1/40000000:Th0H-90.750. Anyone know what this means?

I have no idea how much it will cost to repair. I don't even know what the exact problem will prove to be. It may be quick if it isn't a motherboard problem. I just don't know. Take it in for a service diagnostic, then they can tell you what is involved.

Mac Book Pro will not start on Battery Power

Mac Book Pro will not start on Battery Power although battery at 98% need to connect charger. When started date and time incorrect, comes up as 1st Jan 2012.

What is the exact model of your MBP? The date change often is an indication of power loss to the MBP, such as disconnecting the battery.
If the SMC reset does not solve the situation, post this from your MBP:
Make certain that the power adapter is connected.
Ciao.

Insteade of using mac os on macbook pro, i wanted to install windows 8 pro on mac book pro, will that void my warranty

insteade of using mac os on macbook pro, i wanted to install windows 8 pro on mac book pro, will that void my warranty

Installing any OS you want on your machine will not void the warranty. Only making hardware changes other than those listed as "user servicable" by Apple, or negligence will void your warranty.
I will warn you that there might be SMC or EFI udates you will want for your Mac hardware that are only available if you are runnign Mac OS. For this reason, you may want to keep a small partition on your drive which still has Mac OS installed, or at the very least, keep an external HD around to be able to boot Mac OS. Additionally, if you are having hardware issues, like a failing DVD writer, you may have a harder time getting Apple to repair it under warranty if you can not reproduce the error under Mac OS. When I had the DVD writer replaced in my first MacBook Pro, I found the problems trying to write discs under Windows 7, but when the tech could reproduce an error under Mac OS, he quickly accepted it was a hardware problem and not software. Without reproducing it under Mac OS, he admitted that he might not be able to get them to replace the drive.

My mac book pro will not recognize

My mac book pro will not recognize my hp printer after years of knowing it's connected. USB port works fine with other connections. I have reinstaled it. What do I do?

Hi ...
Go to the HP site and download the drivers (software) that is specific to your HP printer model > http://www8.hp.com/us/en/support-drivers.html
That way you will have the latest software available for your printer.
Then open System Preferences > Print & Scan - Print.
Select the printer on the left then click - (minus)
Now click + and follow the instructions. You may need to turn the printer off then back on before your Mac recogizes the new drivers.
You may also need to click the lock icon in the Print window in order to make changes. You may be prompted for your admin password.

I have OS 10.8.2 and use wireless at home just fine.
When I visit a friend with only a cable modem internet my Mac Book Pro will not connect.
I see that the Mac Book Pro is picking up the internet when I check the internet preference section but it will not open Safari.
What do I need to do connect via a cable modem?

You need to power off the modem for 15-30 seconds, then power back up and then connect. The modem is remembering the last connection (your friend).

My Mac Book Pro will not power on

My Mac Book Pro will not (boot-up) power on.
What should I do?

Do you have the power adapter connected? Does it display a light, amber or green?
Have you checked the battery charge level by pressing the exterior battery level button?
Try a SMC reset:
