Strange things are happening to my MacBook. Please help.
Since buying my first MacBook nearly two years I have not had a single problem with it until earlier this week, when strange things started to happen.
1) The first obvious problem was that my dock lost its settings.
2) Then the green light at the top of the screen was on when I turned on my computer. Although this was resolved by shutting down and restarting, I have no idea why it was on in the first place.
3) Thirdly, my email disappeared from Mail. After exploring, I found out that one of the check boxes in preferences had disabled my account and when I checked it again my email reappeared.
4) And finally, it seems to be getting slower and slower. Whether it is opening a program such as Mail, opening system preferences or restarting, it all seems to be taking longer than I previously remember. However, once things are up and running they are generally fine.
After doing some research I have found two possible fixes: resetting PRAM and resetting the System Management Control. The problem is that although I can read how to do them, I have no idea if they will fix my problems or what the implications of doing either are.
So, do you think it would be a good idea to reset either the PRAM or SMC? If so, which should I do or what order should I do them in?
Also, what, if any, are the risks of doing either? As I understand, my settings for things like the display will be reset but not things like wifi or the firewall, and all my programs, updates and files will remain untouched. Is that correct?
Anyway, I hope that all makes sense and thanks in advance for any help you may be able to offer me.

Hmm, free space is okay, though some folks would say it's a little on the low side.
How much RAM do you have in your computer?

How do i change my iPad language because I went to general and international and changed the language to English, but most things are still in Spanish. Please help me set everything to English
To clarify Settings > General > International > Language is set to English?
and Settings > General > International > Keyboard > includes the English keyboard?
When you are on your Home screen is Settings called 'Settings' in english?

All of the sudden FF is running very slowly & other strange things are happening as well???
I have FF ver. 5 and for about a week now it is taking way longer than normal to load any and all pages. My OS is Windows 7 & I'm on a dual core processor computer that runs each processor at 3.40 GHz.
I can't play any of my games because of how slow it is running. I'll click on a dropdown menu or something of the like like the "Tool's" menu and it will suck up so I'll have to push on it several more times before it will finally stay open and I can choose something. It also takes much longer for it to close down completely. Start up is running at normal for the most part. Every once in a while it will take a while to load and open. It has also been crashing way more than it ever has before and for no apparent reason.
I've done everything I know to do like clearing cookies and history to no avail. I've even run a virus scan which only came up with some tracking cookies, no viruses or anything like that. I have also done a disk clean up and defragged (which I do every week).
I know about 3 days before this started happening I updated the Java stuff and that's it.
I'm at my wits end as I work on the internet for a living and this is making it very difficult and frustrating to get anything done.
Please help!!!!!!!!!!! :( Cheryl-> Tap '''ALT''' key or press '''F10''' to show the Menu Bar

N8-Social-client; strange things are happening !!!
Hi, i just discovered a very strange issue with the social client on my N8; today is one of my FB-friends birthday and when i was checking this friends profile on my N8 there was already a post from myself wich i haven't written. I checked this friends profile on FB on my PC and there i could see that this post was actually from somebody else (wich of course it was since i didn't wrote anything). I logged out on my PC and checked again on my N8's social client and there again it shows my name and picture on that post. What is happening?

Strange Things are Happening...
Hello,
Whenever I turn on or restart my Mac mini v. 10.4.3, it successfully logs in until it reaches the desktop. Then everything disappears, leaving only my background, and then reappears. However it disappears again and goes into an endless loop of everything - the top bar, the dock, any windows open, all icons on the desktop - disappearing and then, around 3 seconds later, reappearing. Whenever I try to start a program it doesn't start. The finder window will open and then disappear with everything else. I have to start my computer in Verbose mode and enter in a string of text (number 7 at http://docs.info.apple.com/article.html?artnum=106464 has the text I must enter). Is there anything I can do to stop my computer from doing this? I posted here before and got a fix, but as I said, it is only temporary. I must do that fix every time I log on. I'm looking to fix it once and for all.
Thank you!Just a couple of things first. 1. Single-user mode isn't verbose mode. Thus, to boot into single-user mode, restart holding down the S key and not the V key. 2. Your problem appears to be the Finder crashing.
Before redoing the steps in the document you cited, do this:
Insert you install/restore disk.
Reboot into Open Firmware: restart holding down the CMDOPT+OF keys. Then, type these in, sequentially, following each by the return key:
reset-nvram
set-defaults
reset-all
The last command restarts the machine; thus, hold down the S key to get into single-user mode.
Once you do that, then type these in, sequentially, following each by the return key:
mount -uw /
mv /Library/Preferences/SystemConfiguration/preferences.plist preferences.old
mv /Users/<yourusername>/Library/Preferences/com.apple.finder.plist preferences2.old
mv /Library/Caches Caches_old
chmod 1775 /
reboot, holding down the C key.
Click on the install icon, select Disk Utility from Utilities, and repair the disk and permissions, quit DU, select Startup Disk, select the Internal HD, and click restart. -
After re-install, strange things are happening with my emails
I had a crash during an optimization adventure with TechTool Pro when I was running 10.4.10. Since I had problems with this version (another issue), I did an archive and install for 10.4.8, with a subsequent upgrade to 10.4.9, and stopped there. So when I moved the mailboxes from the previous system folders to the active ones, my emails "disappeared". The mailbox windows are completely empty. In one mailbox, I "lost" nearly 2000 messages that I needed to archive. On my iMac, I have about 60% of those emails saved and backed up.
I put quotes around "lost" and "disappeared" because I can open the files with TextEdit. They're complete and intact. But I can't open them up within Mail.
I rebuilt the mailboxes, with no success.
So what can I do to get Mail to recognize these invisible email files? Can anyone suggest a way to get Mail to recognize these files?Rather than tinkering with the contents of ~/Library/Mail/, you should have either restored the whole ~/Library/Mail folder as if it was a monolithic entity, or import the mailboxes by means of File > Import Mailboxes.
That said, if Mail doesn’t recognize the messages in those mailboxes even after rebuilding them, chances are that importing them by normal means wouldn’t have worked either. In that case, you may try using emlx to mbox Converter or Emailchemy to convert the *.emlx files to standard mbox format, then import that in Mail as Other. -
I'm using Apple Mail 2.1.3 on a MacBook running OS 10.4.11. A very strange thing is happening. E-mail messages that I either sent or received months ago are showing up in my mailbox and receivers' mailboxes. In one case, a message someone had sent to me wound up in the mailbox of a third person, who was not included in the address list!! I have only two accounts, and have checked everything; only one account is showing the repeats Now, that account is my professional account, and it resides in three places: I use it on the laptop described here, I use it through Apple Mail on the much newer desktop Mac in my office, and I can run it through Web mail on my employer's server, which is where the professional account resides (I have a mailbox there, etc.) That program is called Zimbra.
My personal account is with Earthlink and is not doing the repeats. I access it either through my MacBook's Apple Mail or the Web; the Apple Mail on my office Mac is not configured to access the Earthlink server.
What IS going on here?? My friends, colleagues, and students (I teach college) are mystified by these ancient messages.

I updated to FF4 and after a few days, strange things started happening. How do I recover to normal?
I updated to FF4 and after a few days, strange things started happening.
The groups I had set up disappeared and the Group button is gone.
When I first open the app, it opens 8 - 12 separate windows with 1 blank tab. The orange Firefox button is there with nothing else on that bar. Also, 3 tool bars are blank (i.e. space is there but it's just grey) with NO buttons.
If I want my previously opened tabs, I have to use the "Recently Closed windows" option to get back to where I was when I last closed down. The orange Firefox button is missing from this window but all the original menu items are back across the top.
So how do I get back to the way it is supposed to operate?Have a look here

Hey Davidl678,
Thanks for the question. It sounds like you are unable to download the purchases from your purchase history, because iTunes believes the songs to be in your library. It may be necessary to delete the items from your library, then re-download from your purchase history. Before doing so, you may want to take note of which song are available for re-download:
iTunes 11 for Windows: Delete songs, playlists, or other items

iTunes 11 for Windows: Download previous purchases from the iTunes Store
