My MacBook Pro will not reboot fully after downloading Yoesmite

You could try doing a hard shut down (holding the power button or yanking the battery) and then doing a safe boot by holding the shift key at startup:

Also, not sure if this applies in your case, but I've had that happen when there's a USB drive inserted either in the computer or a connected external keyboard. I did a hard shut down, removed the drive and it went through a normal start up.

HT1436 My Power Mac G5 will not fully boot without safe mode, it only comes to a blue screen where my cursor duplicates in to 2, (one is frozen, one can move by moving the mouse). What is my problem, and how do I fix it?

Great clue Lukas...
One way to test is to Safe Boot from the HD, (holding Shift key down at bootup), run Disk Utility in Applications>Utilities, then highlight your drive, click on Repair Permissions, Test for problem in Safe Mode...
PS. Safe boot may stay on the gray radian for a long time, let it go, it's trying to repair the Hard Drive
Reboot, test again.
If it only does it in Regular Boot, then it could be some hardware problem like Video card, (Quartz is turned off in Safe Mode), or Airport, or some USB or Firewire device, or 3rd party add-on, Check System Preferences>Accounts>Login Items window to see if it or something relevant is listed.
Check the System Preferences>Other Row, for 3rd party Pref Panes.
Also look in these if they exist, some are invisible...

System will not fully boot to display desktop

I HAVE A IMAC MID 2007 INTEL CHIP 2GIG RAM 250 HD, PROBLEM STARTED A FEW DAYS AGO WHEN I WAS UNABLE TO LOGIN INTO MY USER ACCOUNT, OTHER USERS WERE ABLE, CHATING WITH APPLE I DID EVERYTHING POSSIBLE, CHANGED PASSWORD, RESET, NVRAM,, SAFE MODE, NOTHING WORKED, PERMISSIONS, SO I RE-INSTALLED THE OS 10.10, TWICE . AFTER THE INSTALL THE SYSTEM WORK GREAT FAST AND NO ISSUES, UNTIL TO LOG OFF AND SHUT DOWN,
UPON RESTART THE SYSTEM GOES INTO THE NORMAL START UP THE APPLE ICON WITH GRAY SCREEN APPEARS THE BAR RUNS ACROSS THE SCREEN AND THEN THE SCREEN GOES TO A DARK BLUE WITH THE GRAY WHEEL SPINNING, AND SPINNING IT WILL NOT LOAD. I AM ALSO UNABLE TO START IN SAFE MODE.
I HAVE DONE ALL THAT I CAN THINK OFF, HAVE I MISSED SOMETHING? IS THE START UP COMMAND LINE BAD??
BEFORE GOING TO APPLE ANY LAST IDEA'S ?????

Please do not type in all capital letters, that is like shouting and we can hear you just fine. Run Apple's Hardware Test in extended mode 2-3 times, you will need the original install discs that came with the computer 8 years ago to run AHD. The reason to run AHT multiple time is it does not always find errors after the 1st or 2nd pass, however when it does they are correct. Also 2GB of RAM is the minimum specifications to run Yosemite, you should upgrade the RAM to 6GB, the maximum a 2007 can accommodate, if you decide to upgrade the RAM purchase only Crucial or OWC (www.macsales.com), in both case ONLY purchase direct from the vendor.

After downloading maverick, iCloud will not sync across my devices

Since downloading Maverick [10.9], iCloud will not sync across my devices. Mail is not working properly. I'm being asked for passwords from everything.
Also, every time I close and then reopen Mail, I get a message saying "Mail cannot connect to the iCloud account "iCloud", requiring my password, again!
Is there a solution to this? How can I find out if it's server related, etc.?
Thanks to anyone out there that can help!

Try restarting your router and all the other devices.

2, after download of os5 will not sync with PC. "USB device not recognised" ... ANy ideas how to fis this ...

help ... after dowloading OS5 my new iPad 2 will not sync with my PC. the message is "USB not recognised" ... any ideas how to fix this?

I had same problem. By chance, I found a "work-around".
On a whim, I tried plugging the USB cable direct into the PC (its an old 'tower' model that sits under the desk) instead of into the port on the monitor. The PC suddenly recognised the iPad.
Why this makes any difference is a total mystery. But worth trying to see if it helps in your case.

After PC crash iPod will not fully resync iTunes music library

After my PC, using Windows XP crashed, the iTunes music library was able to be copied back to the PC after XP was reinstalled. Music plays fine on PC from iTunes.
When I connected my iPod 30Gb w/color to the PC all seemed fine. It asked if I wanted to sync. I realize that what was on the iPod would be erased, but then reloaded.
Only 512 of about 4000 music files were put back on the iPod. When I connect the iPod to the PC, it says that iPod is up to date and I can disconnect.
How can I get a full resync of ALL the music files?
Windows XP

Try restoring your iPod. Restoring will erase the iPod's hard drive, reload the software and put it back to default settings. Once the restore is complete follow the on screen instructions and it should connect to iTunes and give you a prompt to automatically update your library onto the fresh installation: Restoring iPod to factory settings with iTunes 7

After downloading ff4, ff will not launch. I am connected to the internet but cannot access any pages.

I recently downloaded firefox 4 on to my linux based notepad. This is an acer aspire one. Since Firefox 4 installed I have been unable to access any internet pages, through luanching firefox browser or the search bar on my desktop. I am connected to the internet through my home wireless connection, so don't understand why not able to view pages.

I have the same problem but can go on to some websites but not others. I have tried what was suggested about clearing recent history and also the proxy server but it hasn't resolved the problem.

HP Photosmart Premium All-In-One driver software will not fully install

After downloading and installing the full version of the printer driver (both from on-line site AND from purchased driver CD), the software appears to download fine, but will not fully install. I have run Print and Scan Doctor and tried on-line support, uninstalling, reinstalling the drivers and have tried on-line HP support. My new computer (HP Envy 715 xt) is less than 3 weeks old. I am running Windows 7 Professional 64 bit. The printer/scanner/copier/fax worked fine on my old computer which ran Windows XP. I have tried everything - HP on-line support will not speak to me without charging me, even though my computer is brand new - they insist the problem is with the printer, which is out of warranty.

Uninstall the previous version (without removing your customizations) before installing the new version.
