I have changed my RAM and my macbook isnt booting anymore.
In order to expand my Ram I changed in my macbook (2008) the DDR2 from 2 x 1gb to 2 x 2gb.
When I restarted the mac, it did not reboot anymore. The desktop is just black.
Any advices? Thank you!
Macs can be finicky about RAM modules; even though you have the correct specs the computer might not boot, as you have already discovered. Return the modules (if possible) and purchase your modules from a dealer that supplies RAM especially for Macs; that way you have more reassurance that the computer will behave normally. OWC (Other World Computing) is a reputable place to start.

How do i restore my wifi setting back to the factory settings? I have changed it somehow :/ and now my wifi will not connect. My Airport is on and showing full strength but will not connect.
Ok, if other devices are connecting but just not your MacBook then let's start troubleshooting the MacBook to possibly find out why.
Please try each of the following, in order, until hopefully resolved:
Note the following are excerpts from an OS X Daily article.
* Turn Airport on & off – You can do this via the Airport menu bar or from the Network Preferences. This is the first thing you should try when troubleshooting Mac wireless problems.
* Make sure Wireless/Airport card software & firmware is up to date – This is usually done just by going to the Software Update menu, if there are any updates available for your Mac or Airport, install them.
* Delete and recreate connection – Try deleting and recreating/reestablishing the wireless connection, sometimes a setting can be corrupted and this may fix it.
* Create a new Network Location – Similar to the above suggestion, try creating a new and different wireless network location to see if it resolves the connection problems.
* Change DHCP auto settings to manual – sometimes there is a problem with the DHCP server, and if you manually set an IP address on the network you can be fine. Remember to set the IP to a high number so it wouldn’t interfere with other DHCP machines. As long as you have the subnet mask, router, and DNS settings configured manually as well, this shouldn’t be a problem.
* Flush the DNS cache – Launch the Terminal and enter the following command onto one full line within the Terminal: dscacheutil -flushcache
* Zap the PRAM – Reboot your Mac and hold Command+Option+P+R during restart until you hear another chime, let the Mac boot as usual.
* Delete Wireless Config files – Delete com.apple.internetconfigpriv.plist and com.apple.internetconfig.plist files from ~/Library/Preferences and reboot
* Trash your home directories SystemConfiguration – Remove all files within ~/Library/Preferences/SystemConfiguration/ and then reboot your Mac.
* Reset your Mac’s System Management Controller (SMC) – For MacBook and MacBook Pro’s: Shutdown the MacBook/Pro, remove the battery, disconnect the power, hold the Power Key for 15 seconds. Replace the battery, reconnect power, and zap the PRAM and wait for 2 chimes before letting the keys go. Let boot as usual. -
I have lightroom 5.7 and a macbook pro 10.9.5. Occasionally when I am editing a photo in the develop module, I suddenly get a "file not found" message and the editing ceases to work. There is no "exclamation" icon below the histogram box in the Library module or on the photo in grid view, and the histogram is gone. What is going on? Trying to find it using the "find missing photos" in the library menu does nothing.

I have been using my IMac without a problem when I left it and went back to enter the password the IMac did not see the keyboard. I have changed the batteries and the green light comes up on the keyboard and then starts to flash indicating it is looking for the IMac but nothing happens. I have tried another set of new batteries with the same result. Is there any known problems in this area. The IMac is 5 months old.
Thank you for any helpWhat operating system does your iMac have? (please always post your operating system to prevent confustion).
If it's pre-Lion you will have to set Mail up manually:
Entering iCloud email settings manually in Snow Leopard or Leopard
Entering iCloud email settings manually in Tiger -
I have changed my ID and I can no longer update my apps or see my purchases. I have changed my ID in the store settings.
I have been told by Apple security that the ID does not exist it is now associated with my new ID, they told me to call support there is a pending case but they can not seem to provide an answer. If I log in in with my original ID. It does not recogonise my passwords or any answers I give to the security questions Grrrrrr I wished I never changed my ID!!!

have change my name and my icloud is still using the old account. how do i change it to my new apple ID on my iphone without deleting the backup already in icloud
To change the iCloud ID you have to go to Settings>iCloud, tap Delete Account, provide the password for the old ID when prompted to turn off Find My iDevice, then sign back in with the ID you wish to use. If you don't know the password for your old ID, or if it isn't accepted, and your old ID is an earlier version of your current ID, go to https://appleid.apple.com, click Manage my Apple ID and sign in with your current iCloud ID. Click edit next to the primary email account, change it back to your old email address and save the change. Then edit the name of the account to change it back to your old email address. You can now use your current password to turn off Find My iDevice on your device, even though it prompts you for the password for your old account ID. Then save any photo stream photos that you wish to keep to your camera roll. When finished go to Settings>iCloud, tap Delete Account and choose Delete from My iDevice when prompted (your iCloud data will still be in iCloud). Next, go back to https://appleid.apple.com and change your primary email address and iCloud ID name back to the way it was. Now you can go to Settings>iCloud and sign in with your current iCloud ID and password.

Hello, I have changed my location and credit card for my apple id. All purchased apps I had before are lost. How can I get back my purchased apps? Thanks.
If you are referring to an iDevice, sign out of your new Apple ID and sign back in with your old one - they should all be there.

I have changed my password and still can't get home sharing to work. Get the message "Home sharing could not be activated because the account or password was incorrect." It's what I have used to sign in here! Any help much appreciated.
So I reset my Apple ID password. Which then stopped my MobileMe account from working. Hang on - these were 2 different accounts a while ago, with different passwords!!!
So I have logged back in to MobileMe with my AppleID, and that's working again. After a short wait I can now create Home Sharing again.
Folks, I think we have just had our Apple IDs merged with our MobileMe accounts!! With no consultation or warning.
My guess is that this is the most seamless way for Apple to do it, as the vast majority of people use only one email address and one password for everything. Only those of us who had the same email adress but different a different passwords for MobileMe and Apple ID will have noticed. Annoying for us few, but a clever strategy on Apple's part, becasue we have been driven to fix the issue ourselves by chaning the password, and in doing so we have realised that our mobileme account is now the same thing as our Apple ID. -
I have changed my username and password
I have changed my id and password i cant get my paid apps back
Apps are permanently tied to the ID and password used to purchase them. If you do not remember that information, you cannot update them. If you ned these apps, you will have to repurchase them under your new ID.

I have a Blackberry 8330 and a MacBook. For some reason I started having connectivity issues. The handheld will not sync with the computer via pocketmac. I have uninstalled, etc 15 times. Please help
Hi Peter!
I'm sorry to read that you are having issues with your Sync account.
Your best bet is to follow the steps described in this blogposts and open a bug:

After that, if you don't want to user Sync in your computer, you can stop it with this simple steps:
* At the top of the Firefox window, click on the Firefox button (Tools menu in Windows XP) and then click Options.
* Once the options window opens, click on the Sync tab.
* At the bottom of the Sync tab click on '''Deactivate this Device''' link -
