This morning when I turned my macbook pro on, an alarm sound came from my computer and a thin, short line of light was flashing next to the pulsing light that did not come on. The pulser light has not come on at all today.
This morning an alarm sound accompanied by a flashing thin light happened when I turned on my macbook pro. Now the pulser light is not coming on at all and there is a steady thin light to the left of the pulser that stays on when I close my laptop. Does anyone know what may have happened?
>an alarm sound accompanied by a flashing thin light<
That seems like a memory problem.

Every morning when I "awaken" my MacBook Pro, I come to find that my Safari browser has been closed on it's own. How to fix this? I don't want to lose anything I have possibly typed in a site that I have left to finish working on for later. I checked system preferences and everything seems to be checked appropriately as well as for Safari's preferences.
I am not sure what's going on, because Safari only just recently started doing this and I haven't downloaded anything, nothing out of my regular computer routine. As well, I upgraded to Mavericks when it came out and I have the last version of it too. I can't imagine that Safari would close simply because I don't have or want to upgrade to Yosemite. I am holding off on the upgrade for a bit, because I heard Final Cut Pro 7 can't be run on Yosemite. While I could partition my drive, I really don't want to. Mavericks is fine for right now : )
Okay sooooo...back to Safari...what the! Please help and thanks for any replies ahead of time!
I Hope All Is Well In Your World : )
NynaThere's an Apple help page on the DNS problem - at http://support.apple.com/kb/TS3408
The first thing to try is changing your DNS settings - and for that you need to open System Preferences, then the
Network section.
In Network - click on Advanced - then the DNS tab
under DNS servers - use the + button to enter two extra lines
either these, from google dns
8.8.8.8
8.8.4.4
or from OpenDNS
208.67.222.222
208.67.220.220
then click OK & then 'Apply'
You would need to do that seperately for the Cable (Ethernet) settings and Wireless (Airport) -
Hi, I was given an iMac Flat Screen over the weekend, it turned on ok, this morning when i turned it on there is a circle with a flashing ?, what does this mean, help!
It means that it cannot locate the operating system.
You need to reinstall from the disks that came with the iMac and which the vendor is required to give you. -
when i turn my macbook pro on , the apple logo shows up, but it is just loading. I have tried to turn if off , but the same problem appears. Someone know what the problem is?
Boot into Safe Mode
A Safe Mode boot can take a few minutes compared to a normal boot.
Once you are in Safe Mode open System Preferences > Accounts > Login Items
If you have anything listed there to launch when you startup your Mac, delete all items.
Then go to the Apple menu / Restart.
You can also use Safe Mode to do a "live verification" of the startup disk in case it needs repairing.

When i turn my macbook pro on I get a green apple then just a white screen
When I turn my macbook pro on I get a green and white lined apple then just a white screen anyone help please ?
Hey there Petecaswell,
It sounds like you are seeing a green Apple logo, and then a white screen before the computer boots to your user. I would start by updating your computer:
OS X: Updating OS X and Mac App Store apps
http://support.apple.com/kb/HT1338
Then if the issue persists, I would perform a PRAM reset:
OS X Mavericks: Reset your computer’s PRAM
http://support.apple.com/kb/PH14222
Shut down your Mac.
Locate the following keys on the keyboard: Option, Command (⌘), P, and R. You will need to hold these keys down simultaneously in step 4.
Turn on your Mac.
Immediately press and hold the Option-Command-P-R keys. You must press this key combination before the gray screen appears.Continue holding the keys down until your Mac restarts, and you hear the startup sound for the second time.
Release the keys.
Resetting PRAM may change some system settings and preferences. Use System Preferences to restore your settings.
Thank you for using Apple Support Communities.
All the best,

It's just a white screen with the apple logo. It doesn't move from this screen regardless of how long it's on. The charger is showing a green light. It was amber before I let it fully charge. I've tried turning it on with and without it plugged in. I hear the hard drive start up when I turn it on. And the caps lock light turns on when I hit it. Any suggestions? Help please.
Start your MBP holding the OPTION key. This should show two HDD icons. Select the one on the right, the RECOVER icon. This should display a four option menu. Select Disk Utility and repair the disk.
If no success, the the only other avenue is is a reinstall of the OS.
Ciao. -
HT203254 When I Turn My Macbook Pro On The Screen Dosen't Work
My Macbook Pro Has A Nvidia Geforce GPU And The Screen Won't Work When I Turn It On
Welcome to Apple Support Communities
When you turn on the computer, does it start properly? Do you hear the startup chime and everything else? If so, there may be a display or GPU problem. First, reset the SMC > http://support.apple.com/kb/HT3964
If you have an external display, connect it to your computer and see if it works. If not, it's a GPU issue. If it works, it's a display issue. In both cases, I recommend you to take it to an Apple Store or reseller -
When I search a file called start up disc, nothing shows up. How do I delete files so when my computer starts up, I no longer get a message stating that my start up disc is full and that I need to delete some files?
There is a boot drive inside the computer and it's storage space is filled up.
You need to create a external storage drive and transfer some of your files off the internal boot drive.
TimeMachine doesn't work for this as it's just a rotating backup image of what's on your boot drive, it's not a storage drive for more space and to save things permanently.
So what you need to do is get three external drives from the office or computer store.
I suggest 3-4 separate drives at 1TB each (or more capacity if you really got a lot of stuff), USB 2 is currently fine, the newer USB 3's are more expensive but your Mac doesn't have USB 3 ports, so get the less expensive USB 2 drives and save some money. If you can get Firewire 800/USB combination drives, those would be a better choice as Firewire 800 is the fastest for most Mac's. Only the very new ones have Thunderbolt and the new drives for that are rare and expensive.
Make sure they are self powered drives with their own power supply, not port powered as those are a bit flaky as Apple can just determine the device is drawing too much current from the computer and turn it off.
Note: sometimes if your computer is so full, you might actually have to delete some files in order to be able to get it to function transferring files, so pick ones that you can get new copies again, like free iTunes podcasts or movies for instance.
TimeMachine Drive
The first drive you connect to the Mac is going to pop up a window to ask if you want to make this a "TimeMachine Drive" go ahead and allow it to do that, it's backing up everything on your internal boot drive, it's going to take a long time.
Once it's finished, disconnect this TimeMachine drive and label it as a "TimeMachine Drive"
Extra space /Storage drives
The second drive you connect is going to be your "extra storage drive" basically to free up space off the internal boot drive by transferring files to it.
Formatting:
You first need to format this drive, you use Disk Utility in the Applications> Utilities folder.
On the left will be the 'name of the drive' + "media" click that and then click the Partition tab
Now click 1 Partition, Option: GUID, format OS X Extended (Journaled), give it a name like "StorageOne" and click Apply.
Now click the Erase Tab and Security Option> Zero All Data and click Erase (use the same name) this will take a long time, like 2 hours per 1TB. It's going to check the drive for any errors and make sure it's working.
Note: If the drive fails to format, then perform the Zero All Data first, then visit the Partition tab.
Once the second drive is finished, then do the third drive in the same manner, this time naming it "StorageTwo"
Transferring Data off to the Extra Storage drive
Connect only StorageOne drive and visit your User/Movies folder, it's likely the biggest culprit of oversized files. Create a new folder on the StorageOne drive called "ExtraMovies" and transfer the contents of User/Movies to the "ExtraMovies" folder via drag and drop methods.
Confirm the files were transferred and then delete those movies by dragging them to your Trash can and selecting "Empty Trash" from the Finder menu (if you select Secure Empty Trash on large files it takes a really long time to finish as it's scrubbing the drive, likely unnecessary except for sensitive files)
If you have a large amount of User/Files elsewhere, you will have to search yourself and repeat the same steps to free up room on your internal boot drive.
Once you have made some free space, download this free program to help you visualize where all your space is being taken up.
http://grandperspectiv.sourceforge.net/#download
Once you have completed moving files to the StorageOne drive, connect StorageTwo and copy the contents of StorageOne folders to StorageTwo drive. Both drives have to be connected of course.
Rule of thumb
Maintain TWO separate hardware copies of your User data at ALL TIMES
Because you need more room, thus the storage drives are for extra space. The TimeMachine drive is a backup of your internal boot drive and the second storage drive is a backup copy of the first storage drive. So that way your sticking with the rule of thumb, get it?
Don't connect TimeMachine while your transferring files, or formatting drives, you don't want it to "kick in" while your doing all this heavy work or transferring a large amount of files, I think it does so every hour, which you are going to taking quite some time to do all this work.
Once your all done making room and copying files to the Storage drives, disconnect them and label them and date them.
Reconnect TimeMachine drive
Then connect the TimeMachine drive and it will make a NEW backup of your now newer configuration on your boot drive and keep it updated every time you connect it.
Again, TimeMachine is NOT a storage drive for permanent keeping of data, it deletes old stuff as time progresses. So even though you can "go back in time" and recover a file you transferred then deleted off the your internal boot drive, it won't keep everything forever like a storage drive can.
Consider Cloning your boot drive.
TimeMachine drives can only restore, they are not bootable like a clone is, so a TimeMachine drive isn't a heck of a lot of help if your hard drive fails to boot the computer, so a "hold the option key bootable clone" made with third party software is a very useful as you get to use the computer just like it was before and can get online, grab files off the internal drive and so forth. Even erase and reverse cloning!
The trick with a clone is you make one and keep it disconnected, updating it from time to time. If a software update or install hoses your machine, you can option boot off the clone, grab the latest copy of your files and reverse clone the clone with the updated files back onto your OS X partition, reboot the computer and it's like nothing happened.
It's a advanced technique, you will have to learn a lot more perhaps before attempting it, but it's a lifesaver.
Cloning requires another separate external hard drive and free cloning software.
You can read more about it all here. Take your time, you have a lot to absorb.

When I turn my macbook pro on it makes a strange sound/noise, is that normal?
I got my MacBook Pro in May 2013 and when I turn it on now it makes a stranfe sound/noise, is that supposed to happen?
In Macs with a DVD reader, you may hear the DVD reader move its Read/Write head at Startup, even if the drive is empty.
The guys at the Genius Bar put their hands on these Macs all day every day. They know EXACTLY what the "Bad Sounds" are.
Ask them. It's free, in warranty or out, provided you make an appointment. -

Does anyone know of a way to force quit Mail. It is preventing me from restarting or shutting down my MacBook Pro running Maverick iOS 10.9.
Thanks.itsKeef,
You're having the same problem? Do you ALWAYS have to Force Quit Mail or will it sometimes just Quite when you select Quit? Which model MacBook Pro do you have (e.g., "15-inch Late 2011"), which version of OS X are you running and which version of Mail do you have?
