Cannot get iPhone 4 to talk with Mac Lion using Numpad. Have updated, restarted etc. Have Screen Sharing on. It sees my computer but when I press keys on the NumPad there is no response. I have tried it on the Calculator and on Sibelius. Any clues??
Here's how to do it.
1. App Store, iTunes Store should have the same AppleID on Computer and iPhones. (Free to share apps, music and books... )
2. Person A uses the same purchasing account for everything (ie. email, contacts and ...).
3. Person B have the same purchase account see no. 1 (for App Store and iTunes Store) but create a second AppleID for iCal, e-mail, contacts and etc. -
21" iMac getting white screen and does not boot up
Hi All!
This is my first time to post here but have been using Mac OS since 2009.
I am having issues with my Mid 2011 iMac 21". I keep getting a white screen and it does not boot up.
I am a bit technical so I have done all the necessary steps as below:
1. Powercycle the system (Shutdown, unplug for 10 seconds and replug) = No go
2. Reset NVRAM several times = No go
3. Went to Safe Boot = Vertical white stripes on blue screen appears
4. Tried booting on Recovery Disk = Vertical white stripes on blue screen appears
I'm thinking my video card is faulty now.
Any help guys? I hope my hard drive is not fried
What's worse, my 3 year extended warranty just expired last June and it's only been 3 monthsFirst i can't send it back becuase it didnt have a warranty i purchased it on ebay. second the guy didnt send the install disks with it as he promised i have tried to follow up with him with no luck so hes been reported to ebay. and due to current buisiness expenses cant afford the new software. is there anything else i can do to at least boot the thing so i can figure out whats wrong with it. and has anybody experienced this before and if so how was the issue resolved. soooo frustrated as buisiness is at a stand still till this machine works. p.s.it has osx leopard latest version.

when i active my mac pro all i get is a white screen and it loading and when it fully load its turn off , and it keep on doing the same thing for hours
Hi Shahenaz,
It's a little difficult to understand exactly what's going on with your mac based on the description you gave. Is there anything else you could add? Is it stuck in a reboot loop? Or is it just showing a white screen forever?
I had pretty much the same problem a few days ago, and was worried my mac was screwed permanently, but I got it fixed up no problem!
Follow these steps to try and troubleshoot/fix the problem.
1. Boot into OSX Recovery Mode
First, turn off your Mac. If it isn't responding, or is stuck in a reboot loop, just hold down the power button until it turns off, and you hear the fans stop. Then boot it while holding the Command and R keys. If it successfully boots into OSX Recovery Mode, continue with this step. If not, skip to step two. (My Mac couldn't successfully boot into the recovery mode, so I had to go to step 2)
Select "Disk Utility" from the list of options, and find your built in hard drive from the list on the left. Usually there are two listings/names for your drive. The first should be something like "500GB longchainoflettersnumbers Media". Then the one below will be a little easier on the eyes, named Macintosh HD, if you haven't changed its name. That's the one you want, click it.
Now go to the "First Aid" tab. Click on the "Verify Disk" button in the bottom right corner, and let it do its thing. Once that's done, hit repair disk, also in the bottom right corner. If your disk is corrupted, you may need to run the repair process several times, before it comes up completely clean.
Once this is done, select Shut Down from the Apple menu and, once your Mac is completely off, turn it back on like normal. If it works, great. If not, proceed to step two.
2. SafeBoot
Sometimes, when a mac is acting up and doesn't want to start, all it takes is a safe boot, followed by a regular restart. Or maybe you recently installed a program that either has malicious or errored coding that's causing your troubles. This is where Safe Boot comes in.
Turn off your mac, and reboot it while holding Shift. (If you want to see the process that's going on in the background, boot while holding Shift, Command, and V. This will enter something called Verbose Mode).
If it boots successfully into Safe Mode, great. If you believe that there's a particular program that you recently downloaded that might be causing your trouble, now's the time to delete it. If not, just reboot normally and see if it works! If it doesn't, or if your Mac didn't even Safe Boot like mine, proceed to step 3.
3. Fsck!
For this step, you're going to be booting your mac into Single User Mode. I'm not going to go into details as to what this step does, but it works for some people. Here are the steps.
Turn off your mac, and reboot it while holding Command and S. The screen should go black, and you'll see some white text run across the screen, wait a few seconds, until you see the command prompt. Now type
fsck -fy
and hit the Enter key. This will run a series of system checks, which could take a few minutes. Be patient on this part. Once it's done, it will show one of two messages:
1. "The volume (your Mac) appears to be OK
or
2. "File System Was Modified"
If you got message 1, type reboot and press Return. Hopefully your computer works after this - if not, proceed to step 4.
If you got message 2, run the same command again until you get message 1. If it doesn't seem to be working, turn off your system and proceed to step 4.
If you couldn't even boot into Single User Mode in the first place (like me), go to step 4 anyways.
Step 4: Reset the NVRAM
The NVRAM is another kind of RAM that stores data like the computer volume you had set before you turned it off, or the screen brightness, resolution etc. This memory is saved, unlike with regular RAM. Resetting it isn't harmful to your system, it will just put your screen brightness, volume, etc. to defaults.
Turn off your Mac, and reboot while holding Command, Option, P, and R, and continue holding them down until you hear the computer restart again.
I can't really explain why to do this step, I just know it works for some people, and seems to be what unbricked my MacBook Pro. If none of these steps, fixed your Mac, well the situation is looking pretty grim. Try setting up a meeting with a Mac Genius at your local Apple store. However, I know that many other people with these symptoms ended up having a logic board failure. Apple can swap out your logic board for a new one, but the price is pretty hefty, somewhere around $300 I believe.
Well I wish you luck, I hope this helped you! -

I recently bought a Macbook Pro, this is my first Mac. I restarted it, but when it started back there was a plain white screen and then it prompted me to insert the reboot disk. Has anyone else had this problem and is there a way to do this manually like with PC's?
The new Mac's came with OS X Lion 10.7 and there are no boot disks.
Since it's so new, take it back to the Apple Store and let them deal with it.
If not you can hold Command and r (as in rotten) keys down and boot the computer.
You'll be presented with a several options, including one to reinstall OS X Lion provided you have a Apple ID, which means you have to use Safari in there to set one up. To do that you need to set up a email account with Google or Yahoo. Once you get the ID, then you can download Lion and reinstall it.
It's so stupid not having a copy of the OS on hand to perform your own repairs.
Of course Apple will be happy to sell you a $69 Lion USB stick.
Like I said, take it back to the store, and try to get your money back, that will force them to think about just giving you a replacement machine that works.
Lion doesn't work really but it can be acceptable until the patches get released. -
My new Mac mini (3 month) didn't start up, all that appeared was a white screen and a flashing folder with a question mark inside it.
I followed by recommendations from 'Everything Mac': "shut it down by pressing and holding the power button for about 5 seconds.
Then hold down the Option key and press the power button again to start up the Mac mini. Keep holding down the Option key until
the Mac mini starts up."
But I got a Wi-Fi button only to chose and connect the local network. I connected to my network and I can't use this connection
becouse no icons.
Could you please help me?Your Mini (running 10.6.4) should have come with grey-colored install disks. Now is the time to put them into service. Turn on your computer so that there is power to accept disk #1 into the optical drive. Once the disk is in the drive, shut off the computer by holding the start button down until it powers off. Then turn it on this time holding down the "C" key to make the computer boot from the disk. The question mark that you saw indicates that the computer cannot find a bootable volume. This can happen due to corrupted system files or an improper shutdown etc. Once you are in the "Installer" you can choose Disk Utility from the Utilities Menu in the menu bar. Use it to repair the disk and to see if that can solve your trouble.

When I turn on my IMAC I get the white screen and it won't start
I was working on my IMAC and it froze, so I restarted it a couple of times. It is now not restarting and I get a white screen and spinning circle. What can I do to get the computer to start up or do I need to take it in to the Apple store.
First, use Disk Utility to repair the drive and permissions. Second, reinstall OS X. This will require booting from an installer DVD or the Internet.
Because you have not provided any information about the exact model you have nor version of OS X installed, I cannot provide more information. -

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 boot failure is to secure your 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 your last backup, you can skip this step.
There are several ways to back up a Mac that is unable to boot. You need an external hard drive to hold the backup data.
a. Boot into 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.”
b. If you have access to a working Mac, and both it and the non-working Mac have FireWire or Thunderbolt ports, boot 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.
c. 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
Press and hold the power button until the power shuts off. Disconnect all wired peripherals except those needed to boot, and remove all aftermarket expansion cards. Use a different keyboard and/or mouse, if those devices are wired. If you can boot 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.
If you've booted from an external storage device, make sure that your internal boot volume is selected in the Startup Disk pane of System Preferences.
Step 3
Boot in safe mode. Note: If FileVault is enabled, or if a firmware password is set, or if the boot volume is a software RAID, you can’t do this. Post for further instructions.
Safe mode is much slower to boot 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 your login password in order to log in. If you’ve forgotten the password, you will need to reset it before you begin.
When you boot 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, your boot volume is damaged and the drive is probably malfunctioning. In that case, go to step 5.
If you can boot and log in now, empty the Trash, and then open the Finder Info window on your boot 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 reboot as usual (i.e., not in safe mode.)
If the boot process hangs again, the problem is likely caused by a third-party system modification that you installed. Post for further instructions.
Step 4
Sometimes a boot failure can be resolved by resetting the NVRAM.
Step 5
Launch Disk Utility in Recovery mode (see Step 1.) Select your 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 reboot as usual.
Step 6
Reinstall the OS. If your Mac was upgraded from an older version of OS X, you’ll need the Apple ID and password you used to upgrade.
Step 7
Repeat step 6, but this time erase the boot volume in Disk Utility before installing. The system should automatically reboot into the Setup Assistant. Follow the prompts to transfer your data from a backup.
Step 8
A dead logic-board battery in a Mac Pro can cause a gray screen at boot. Typically the boot failure will be preceded by loss of the startup disk and system clock settings. See the user manual for replacement instructions.
Step 9
If you get this far, you're probably dealing with a hardware fault. Make a "Genius" appointment at an Apple Store to have the machine tested. -
My 13" macbook just stopped working. When you turn it on you get a white screen and hear a repetitive clicking sound on the left side. Is this the hard drive? Any suggestions on replacement drives?
ThanksPut your install DVD into the optical drive (CD/DVD drive) and reboot. Be sure to either use the disc that came with your Mac, or, if you installed a later Mac OS X version from disc, use the newer disc. As soon as you hear the boot chime, hold down the "c" key on your keyboard (or the Option Key until the Install Disk shows up) until the apple shows up. That will force your MacBook to boot from the install DVD in the optical drive.
When it does start up, you'll see a panel asking you to choose your language. Choose your language and press the Return key on your keyboard once. It will then present you with an Installation window. Completely ignore this window and click on Utilities in the top menu and scroll down to Disk Utility and click it. When it comes up is your Hard Drive in the list on the left?
If it is, then click on the Mac OS partition of your hard drive in the left hand list. Then select the First Aid Tab and run Repair Disk. The Repair Disk button won't be available until you've clicked on the Mac OS partition on your hard drive. If that repairs any problems run it again until the green OK appears and then run Repair Permissions. After repairing use Startup Disk from the same menu to choose your hard drive for restarting from your hard drive.
If your hard drive isn’t recognized in Disk Utility then your hard drive is probably dead. -
Macbook pro boots to white screen and a ?
macbook pro boots to white screen and a ?
Gus@MaggiesFarm,
try this: boot your MacBook Pro into Recovery mode by holding down a Command key and the R key as it starts up. Once the Mac OS X Utilities menu appears, select Disk Utility. On the left-hand side of the Disk Utility window, select your internal disk’s boot partition (typically called “Macintosh HD”). On the right-hand side, press the Verify Disk button if it’s not greyed out; if it is greyed out, or if it reports that errors were found, press the Repair Disk button. Once the verification/repair is completed, exit Disk Utility and select Restart from the Apple menu to restart in normal mode. Does it get past the white screen now?
