My new mac book air will not show old emails. how can i fix this problem

my new mac book air will not show old emails. how can i fix this problem

The answer depends on a number of factors, such as the following:
If you have more than one email account, does this problem affect one, some, or all of your accounts?
Where did you last see this mail -- in your Inbox(es)? in some other folder(s) outside your Inbox(es)? somewhere else?
How old is the missing email -- yesterday? just before you got the new computer? over a week? over a month? over a year?
How are you reading email -- with the builtin Mail application? with some other mail-reading application? with a web browser?
How do you access your email on the server -- IMAP? POP? Exchange? web browser? other?
What version of OS X is on your new computer -- Mavericks (10.9.x)? Mountain Lion (10.8.x)?
Did you migrate your data and applications from your old computer when you set up your new computer?
For example, if the missing mail is the mail that was in your Inbox before you got the new computer, you are reading it with the builtin Mail via POP, and you failed to migrate data, then the mail was left behind on the old computer. The same would be true if the mail was in "On My Mac" mailboxes and you failed to migrate data.

HT3205 My mac book pro will not turn on. The light on the battery charger is weak, barely visible.

I recently purchased an iphone 5s. After returning home form the apple store, so very excited to sync my new device, my mac book pro won't turn on.
it was last used 3 hours prier to me returning home. It won't turn on, the charger light is weak, barely visible. When I plug the charger to another device it works fine. Before I take it to be repaired I would like to get a general idea of the problem, as well as an estimated cost.

A. We have no idea what the problem might be.
B. We have no ideaa what it will cost to repair it.
C. Please make a Genius Appointment and take it in for service.

Mac Book Pro will not turn on

I have a 2011 MBP 15 inch. I recently updated to OS X Yosemite. I was using my Mac last night when all of a sudden the display went to the restart screen. I went to log back in and it showed the bar, which i'm assuming meant it was updating the system. It got maybe a 1/3 of the way done when it restarted it's self again. It did this a couple of times all the while my caps lock button is lit up to be on, but when I went to log in I clicked it off, but it showed the icon stating that cap lock was then activated. After the fourth or fifth time logging in the screen went black and it will not turn back on. The caps lock button is still lit, but there is nothing when I push the power button. I would greatly appreciate any advice that someone could give me as I'm a senior in college and that computer has my life on it.
Thank you for your tips and advice.

Hey kgary1323,
Thanks for the question and detailed information. Since your caps lock is lit, we know that the issue is not related to power - so that’s good news. Next, we’ll want to troubleshoot the video connection:

Home Sharing one Mac Book Air Will Not allow Music to Transfer to the MAC

First here's what we have
2 users, (2) iPhones and Mac Book Pro and Mac Book Air and a Windows PC
All computers are set to manually manage music.
I have home sharing set on all 3 computers. When l log into either the Macs or the PC I can drag music I want between either computer with no problems. All computers are authorized. When my wife logs into her account on her Mac Air she cannot move any music from the shared computers. We have separate iTunes accounts. Anyone have any idea, why when using her user account she cannot drag the music files over to her Mac Air

for home sharing to work, iTunes must be authorized to the same user account.

I am running version 10.8.5, 2.66 Ghz 4 GB 1067 Mhz DDR3 late 2008 model. An anyone help? Or is the hardware just dead? Thank you in advance.

My mac book pro will not turn on

I was downloading new software it was taking a long time
I realised I had Uni work I need to do so I turn my Mac Pro off
While it was still downloading/ rebooting ...
My mac made a load noise when I turned it off
I knew that wasn't a good idea once I turn it off
Now when I turn my laptop on the screen is black

Try SMC and PRAM resets and see if they will liven up your MBP:http://support.apple.com/kb/HT3964

My mac book air will not connect to the Internet

I have a late 2010 MacBook air which has been connecting to the Internet by wifi until very recently. It now connects to the wireless router but not the Internet, there is a alert saying there is no Internet connection. My iPhone and iPad both connect to the Internet so I don't think there is a problem with my Internet connection.

Ok then.
Would you like to give the forum some more details?
If not then there is very little anyone could suggest.

My MacBook Air will not turn on. I get a white screen with the apple logo and a spinning star that just does that for hours

My MacBook Air will not turn on. I get a white screen with the apple logo and a spinning star (search icon). It will spin for hours and never go away unless I power off.

Take each of these steps that you haven't already tried. Stop when the problem is resolved.
To restart an unresponsive computer, press and hold the power button for a few seconds until the power shuts off, then release, wait a few more seconds, and press it again briefly.
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 a desktop Mac hangs at a plain gray screen with a movable cursor, the keyboard may not be recognized. Press and hold the button on the side of an Apple wireless keyboard to make it discoverable. If need be, replace or recharge the batteries. If you're using a USB keyboard connected to a hub, connect it to a built-in port.
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 in OS X 10.9 or earlier, or if a firmware password is set, or if the startup volume is 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 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.
