My mac book keep on beeping and make the beep sound 3 time (same goes to the light) and it won't start up. What should i do?

If you recently installed new ram, make sure it is seated properly.
If that doesn't work try removing one stick at a time to see if one is dead or put original ram back in.

Mail won't upload? and messages won't delete? HELP PLEASE!

hello, i have no idea how to use this discussion board, but my mail on my mac will not upload/recieve new mail. i have clicked and refreshed the 'get mail' button and nothing happens. sometimes beside the inbox tab a triangle appears with an exclamation point and it has a message saying mail can't be recieved. Also, i composed a message with picture in it, and the message was too big, so i decided to just not send it, and a tab labeled "on my mac" has a tab underneath of it labeled 'recovered messages' and the email i composed with pictures appeared in that like an inbox 26 times. they won't delete and neither will my trashed emails. help please!!

Why has my mac book made a beeping sound?

my macbook has mad a beeping sound does any one know why?

Beeps on startup:
1 beep = no RAM installed
2 beeps = incompatible RAM types
3 beeps = no good banks
4 beeps = no good boot images.
5 beeps = processor is not usable

Mac book keeps crashing iPhoto and safari

Safari and iphoto can't be open at the same time without them both crashing and iphoto crashes whenever I try to upload... I cleared the cache, rebooted etc. but still keeps happening....

Launch the Console application in any of the following ways:
☞ Enter the first few letters of its name into a Spotlight search. Select it in the results (it should be at the top.)
☞ In the Finder, select Go ▹ Utilities from the menu bar, or press the key combination shift-command-U. The application is in the folder that opens.
☞ Open LaunchPad. Click Utilities, then Console in the icon grid.
Step 1
Make sure the title of the Console window is All Messages. If it isn't, select All Messages from the SYSTEM LOG QUERIES menu on the left. If you don't see that menu, select
View ▹ Show Log List
from the menu bar.
Enter the name of the crashed application or process in the Filter text field. Select the messages from the time of the last crash, if any. Copy them to the Clipboard (command-C). Paste into a reply to this message (command-V).
When posting a log extract, be selective. In most cases, a few dozen lines are more than enough.
Please do not indiscriminately dump thousands of lines from the log into this discussion.
Important: Some private information, such as your name, may appear in the log. Anonymize before posting.
Step 2
In the Console window, look under User Diagnostic Reports for crash reports related to the crashed process. The report name starts with the name of the process, and ends with ".crash". Select the most recent report and post the entire contents — again, the text, not a screenshot. In the interest of privacy, I suggest that, before posting, you edit out the “Anonymous UUID,” a long string of letters, numbers, and dashes in the header of the report, if it’s present (it may not be.) Please don’t post shutdownStall, spin, or hang logs — they're very long and not helpful.

My Mac Book Keeps on shutting and I get this message when it reopens... Does anyone know what it means

Make a "Genius" appointment at an Apple Store to have the machine tested. You may have to leave it there for several days.
Print the first page of the panic report and bring it with you.
Back up all data on the internal drive(s) before you hand over your computer to anyone. If privacy is a concern, erase the data partition(s) with the option to write zeros* (do this only if you have at least two complete, independent backups, and you know how to restore to bare metal from any of them.) Don’t erase the recovery partition, if present.
*An SSD doesn't need to be zeroed.

Mac Pro won't start up- HELP please.

I had a white screen a month ago .After buying a new harddisk and reistalling the whole system 10.6.5 and reistalling all programs from ground zero, I had the MPro working nearly for 2 weeks. But Suddenly today It got a frozen screem with a black curtain. I disconected all the external devices and after starting up I got a loading bar and then the spining wheel but it doesn't turn on.
Is this a sign that I need to change the motherboard?

You may be experiencing a Kernel Panic as seen and described in Apple doc.#106227. If not, disregard.
Bad or incompatible RAM is the most common cause of KP's. It could just need to be reset……. to make sure there's a good connection.
Try pulling any added RAM, especially if it's not OWC, Crucial or Kingston. Then run it with original RAM. Ground yourself while doing so. Keep in mind a bad stick of RAM can cause directory corruption, so Repair Disk after pulling the RAM. If it still does KP's, try removing the original RAM and running on two sticks of the added RAM.
Here's a great site for Resolving Kernel Panics. Please do all the steps in order, even if you don't think you need to do a certain step.
Here's a great MacFixIt article.

Shows flash player is installing, but then can't find it and it won't work. Help please

Hello. My flash playe worked just fine until this morning. I turned my computer on, went to a facebook app., and got a message "if doesn't load in the next 10 seconds, upgrade flash by clicking here" which brought me to adobe I have an Acer laptop, and am running Internet Explorer 7.
I've done everything I can, but can't get flash player to work. I've uninstalled, re-booted, re-installed, re-booted. I've made sure my security zones are on medium, I've temporarity disabled my virus protection program while uninstalling and installing. I've went under tools, manage add ons, to enable it, but the only adobe add-on listed is adobe PDF link helper and it's enabled. I've checked to make sure Java script is enabled, I've made sure I have the 32 bit browser, I've done everything I could find to do (I've worked on this for hours today).
When I click to download from adobe site, it shows it installing without a problem, goes all the way through, shows done, then shows to close download manager. If I go through control panel to 'uninstall programs' adobe flash is listed. If I go through start, adobe flash is not listed in my programs and does not come up when I search under start.
So, from I can find, I can download and install it, but then it's not there and doesn't work. Please Help. I've struggled with this all day, and it's very frustrating, and the only way to reach adobe is to pay $39 for a phone call. I really need help on this, it would be very much appreciated. Please, and thank you.

Hi, and thanks again for taking the time to help me with this, I sure appreciate it. I ran a disc cleanup, then I went in under internet options and deleted the cookies and such. I got rid of the uninstall and install programs I had in the download folder but still have the ones on the desktop.
I went to Windows/System32- but I don't have a Macromed folder there. I have one under the SysWOW64 folder though, a Macromed folder, with a Flash folder under it, with files uner it:
Flash10l.ocx- ActiveX control,
FlashInstall- Text document,
FlashUtil10l_ActiveX.dll- Application extension,
FlashUtil10l_ActiveX- Application (with a red file by it, and it opens the uninstall program), and
install- Text Document.
The two text documents say they were created last year, but the other three say they were created today.
And like I said, these are under the SysWOW64 folder. The System32 folder does not have a Macromed folder under it at all, and instead of being in alphabetical order from top to bottom, they start with Z and the A's are at the bottom, if that means anything. I called my frienfd and had her check her computer step by step as I did mine, and hers doesn't have a Macromed under the System32 folder either, but does the SysWOW64 file, and it has the same files I do, except two of the first one, the Flash10l.ocx, but with different dates on it.
I ran my virus scan, avast, and it didn't find anything. I did close the browsers to run the Window Defender and Malwarebytes, and tried it again a few minutes ago, and they are still saying they find nothing. The malwarebytes found 7 things this morning when I ran it, but hasn't found anything since.

I've moved itunes library onto new computer and now it won't sync. I did the back up and restore things and tried to sync, and although I've said yes to erasing and syncing, the sync won't start. Help please!

It just keeps telling me "The session failed to start"

It means the device is in recovery mode. You'll need to reconnect it to iTunes and restore it again.
You may need to connect it in recovery mode manually using the instructions in this Apple support document.

Both Lightroom 4 and 5 won't open. Help Please.

I tried installing lightroom 4 on two different pcs. Both running Windows 8 32bits. When the installation is done, I try to open it. LR does shows up in the "dock" on the bottom of the screen, but it doesn't open.
If I put the arrow/mice on it, it shows up in small the registration screen. But it just won't shows up.
I tried with LR 5, thinking the problem would be solved. But no. Still nothing.
Here's a screenshot to help you get a better understanding of the situation.
If I click on it. It won't shows up.
I had LR4 with Windows 7 and it worked great. Is Windows 8 the problem ? Is there a solution beside downgrading to Windows 7? Althout, I had no problem with the LR5 beta on Windows 8.

Hi shldr2thewheel,
it has been a while since we have last spoke, I would like to let you know, I am still working on getting used to the switch from windows to a Mac/Apple system. I do have a new question for you, I did purchase In Design CS5.5 through journeyed.com through Cuyahoga Community College of which I attend as a student, is there a way to purchase an online book through iTunes to learn that as well? Also, you know me, the struggling student, I would also, when and if the book can be purchased through the iTunes, would need to know if you do know of a much easier book for struggling students like myself and at a reasonable price as well for the In Design CS5.5 program. Our campus bookstore had closed early, and, so did the colleges library and our local library here where I do live, so, I cannot go to either place to purchase a book or to take out a book, plus cash funds are low at this moment as well but, I do have money left on the iTunes account to use, if it can be used. So, can it be used, the iTunes money, towards finding a low priced online book? I am in great need of assistance as I have a project due for my one course for this Tuesday, September 4, 2012.
Sincerely in need of help once again,
Kim

HT1379 I can't turn on my Mac Book Pro. If I press the power button will beep 3 times (won't turn on) stop and beep 3 times again. What can I do?

Three beeps at startup almost always indicate bad RAM. You probably need to get your RAM replaced. Bring it in to Apple for a definitive diagnosis if you are unable to run the Apple HardwareTest
