Freezing Mac after trying to upgrade to Yosemite

Those are the screens I will still be getting and spend 4 times with Apple-support chat, restarted with command,option,P,R and still the same.

No non-Apple kexts present.
a really wacky hfs error is occurring.
It is crashing in backupd.
I expect there is something unusual or damaged about the drive you are trying to update. Yosemite makes some big changes to the hfs layout of the drive, and it appears that is not working.

Currently on Mountain Lion. Tried to upgrade to Yosemite. Computer is now locked onto OSX installation page. No access to finder or anything. Have to push off button to shut computer down.

iMac running Mountain Lion.... Yesterday, I tried to upgrade to Yosemite. System seemed to be upgrading. However, the OSX installation window is now frozen on the computer with the blue bar showing installation complete. I do not have access to even the finder. Force quitting with keys is not working. The only way I can shut the computer down is to hold down the on/off button. Restarting brings up the same frozen OSX installation window. What to do?

There are three ways:
A. Reinstalling Yosemite, Mavericks, Lion/Mountain Lion Without Erasing the Drive
Boot to the Recovery HD: Restart the computer and after the chime press and hold down the COMMAND and R keys until the menu screen appears. Alternatively, restart the computer and after the chime press and hold down the OPTION key until the boot manager screen appears. Select the Recovery HD and click on the downward pointing arrow button.
Repair the Hard Drive and Permissions: Upon startup select Disk Utility from the main menu. Repair the Hard Drive and Permissions as follows.
When the recovery menu appears select Disk Utility. After DU loads select your hard drive entry (mfgr.'s ID and drive size) from the the left side list. In the DU status area you will see an entry for the S.M.A.R.T. status of the hard drive. If it does not say "Verified" then the hard drive is failing or failed. (SMART status is not reported on external Firewire or USB drives.) If the drive is "Verified" then select your OS X volume from the list on the left (sub-entry below the drive entry,) click on the First Aid tab, then click on the Repair Disk button. If DU reports any errors that have been fixed, then re-run Repair Disk until no errors are reported. If no errors are reported click on the Repair Permissions button. Wait until the operation completes, then quit DU and return to the main menu.
Reinstall OS X: Select Reinstall OS X and click on the Continue button.
Note: You will need an active Internet connection. I suggest using Ethernet if possible because it is three times faster than wireless.
B. Install or Reinstall from Scratch
Be sure you backup your files to an external drive or second internal drive because the following procedure will remove everything from the hard drive.
Boot to the Recovery HD:
Restart the computer and after the chime press and hold down the COMMAND and R keys until the menu screen appears. Alternatively, restart the computer and after the chime press and hold down the OPTION key until the boot manager screen appears. Select the Recovery HD and click on the downward pointing arrow button.
Erase the hard drive:
1. Select Disk Utility from the main menu and click on the Continue button.
2. After DU loads select your startup volume (usually Macintosh HD) from the
      left side list. Click on the Erase tab in the DU main window.
3. Set the format type to Mac OS Extended (Journaled.) Optionally, click on
        the Security button and set the Zero Data option to one-pass. Click on
      the Erase button and wait until the process has completed.
4. Quit DU and return to the main menu.
Reinstall Yosemite: Select Reinstall OS X and click on the Install button.
Note: You will need an active Internet connection. I suggest using Ethernet if possible
            because it is three times faster than wireless.
C. Internet Recovery
Install OS X Using Internet Recovery
Be sure you backup your files to an external drive or second internal drive because the following procedure will remove everything from the hard drive.
Boot to the Internet Recovery HD:
Restart the computer and after the chime press and hold down the COMMAND-OPTION- R keys until a globe appears on the screen. Wait patiently - 15-20 minutes - until the Recovery main menu appears.
Partition and Format the hard drive:
Select Disk Utility from the main menu and click on the Continue button.
After DU loads select your newly installed hard drive (this is the entry with the mfgr.'s ID and size) from the left side list. Click on the Partition tab in the DU main window.
Under the Volume Scheme heading set the number of partitions from the drop down menu to one. Click on the Options button, set the partition scheme to GUID then click on the OK button. Set the format type to Mac OS Extended (Journaled.) Click on the Partition button and wait until the process has completed. Quit DU and return to the main menu.
Reinstall Yosemite: Select Reinstall OS X and click on the Install button. Be sure to select the correct drive to use if you have more than one.
Note: You will need an active Internet connection. I suggest using Ethernet if possible because it is three times faster than wireless.
This should restore the version of OS X originally pre-installed on the computer.

Install more RAM in the computer; the Mac needs to have at least 2GB of RAM and should have 4GB or more first.

What OS is on the Install/Restore DVD that came wit your G5? If Tiger 10.4.x, you will need a black, retail Leopard install DVD. There is no free download of Leopard, only free updates once you have installed the base OS.
First use your Mac's Install/Restore DVD to install an OS & apps. Then upgrade the OS.
Leopard is no longer available at the Apple Store *but may be available by calling Apple Phone Sales @ 1-800-MY-APPLE (1-800-692-7753)*.

Photoshop CS5 64x partially freezes up after trying to save a file !

Photoshop CS5 freezes up after trying to save a file. It doesnt freeze up totally .It just leaves me about 3 choices from the drop down menu.
This only happens with the installed 64 bit version and not with the installed 32 bit version?
My Operating System(OS) is Win.7 64x. I have all the latest versions of everything installed! The computer is run by an Intel 7 930 quad core processor with 8GB DDR 3 Ram(1600Hz). I have reinstalled both Photoshop Versions(32&64 bit versions) but still get the same problem.
The image files that i have tried to save are not corrupted as I can save them using the 32bit ver. But cannt save them via the 64 bit ver. without the software partially freeing up! Would be most grateful for any proper and constructive advice in order to remedy this problem.
All the best from NUGCS5.

Re comparing to Irfan View:
For what it's worth, Irfan Skiljan's marketing strategy is just different than Adobe's. He may actually be more wealthy for having written that one application than most any Adobe engineer has made from Photoshop (well, maybe not Mr. Knoll). I know I've paid Irfan for my copy. By some counts he has hundreds of millions of copies in circulation. If only one in a thousand people paid him the $10... And who knows what Google pays him for piggybacking their stupid toolbar (grrrrr, but it's deselectable)...
I agree with you that recovering a corrupted file at all costs is way better than "nope, can't open it for you", don't get me wrong.
Just keep in mind that IrfanView is not chopped liver - it's Irfan's lifetime achievement, and he may well have a few unique tricks all his own up his sleeve. In some parts of the software world a bright individual can still shine, even amongst the giants.
At least you have a workaround: Open it in Irfan View, Copy, File-New in Photoshop, Paste, Merge Down.

Can I download an app from the Mac App store without upgrading to Yosemite

I purchased the Lion upgrade through Apple for my Late 2006 MacBook and was given a redemption code to use in the Mac App store. I cannot open or download the Mac App store without upgrading to Yosemite, which is impossible with my old MacBook. Any help would be appreciated.Thanks

If for some reason App Store is not showing on your 10.6.8, check Apple logo > about this Mac And the version number. Anything less than 10.6.6 would explain it. If that is the case, software update, preferably to the 10.6.8 Combo.

HT201364 Trying to upgrade to Yosemite

I am trying to upgrade to Yosemite and I have Snow Leopard 10.6.8 installed and 2GB of memory and plenty of free space on my hard drive, but when I try to upgrade it just says, "This version of OS X 10.10 cannot be installed on this computer" with no further explanation. Any ideas?

A Mid 2007 MacBook is a MacBook2,1.
According to Eric Root it must be 3,1 or higher and I have 2,1.
The 3,1 number is for a MacBook Pro, you have a MacBook, not a MacBook Pro. The minimum requirement for a MacBook is 5,1, as stated by Eric.
See: http://support.apple.com/en-us/HT201608 This will translate model identifier numbers to introductory year model names.

If you restored from a backup, the backup may be corrupted.

Tried to Upgrade to Yosemite - Mac Got Locked! - HELP!!!

Today I tried to upgrade my late 2013 15" MacBook Pro Retina from Mavericks to Yosemite. After launching the installation, the computer restarted and within 30 seconds it displayed a screen asking for a four-character password and the following message "Enter your system lock PIN code to unlock this Mac."! I cannot bypass this screen and I have no clue what this password might bemas I never set one.
I called Apple Canada and was with them for four hours on the phone. No result other than the fact that my computer appears to be iCloud locked. I only remember experimenting and trying to lock it once through my iClold account 6-8 months ago and the procedure had no effect on the Mac at that time (although it locked my iPnone and iPad). The Apple guy thinks that that the very old command might have activated now. But how do I unlock it my computer now?
On the phone, Apple advised me to go to an Apple Store to see the Genius Bar. But the earliest appointments are available on Wednesday next week and Saturday I need to fly to the UK on business for a week and all my work files and presentations I need to make are on the locked computer.
What has Apple done to my computer? How could they lock me like this out of my data? Please let me know what do I have to do to recover access to my computer and data as soon as possible?
Many thanks.

I did the same thing, I realised what I did wrong after it was too late and ended up with the 'white no entry sign' on the black screen.
I did manage to sort it, but because the solution happened so fast, I can't recall the exact details, but here is a general guide: Please read all of this before following the sequence I went through.
After much messing around searching the net on another machine and getting nowhere I decided to do a re-install the system. I started the Mac holding down Command-R. I then opted to re-install the software thinking that I was going to lose everything. I clicked on the Install button and it would not let me re-install the system because the drive was locked. This turned out to be an amazing stroke of luck.
I then went to Time Machine out of curiosity more than anything else, and this is where I can't remember exactly what happened. I think I went to see if there were any backup, knowing there was not! but it gave me the option to 'unlock' the drive. I did this, immediately shutdown and re-started and I was then able to get back in as normal. I then went straight into Filevault and made sure that it was switched off.
I hope that helps.

IMovie '11 freezes on launch trying to upgrade library

Hi everyone,
I recently bought iLife '11.
I launched iMovie '11 but it froze on the first launch, trying to upgrade the "iPhoto movie library" from my '09 library.
I restarted my mac several times, and upgraded to iMovie 9.0.1, but I still have the same issue. iMovie freezes every time, I always end up force-quitting it after a few hours.
I have a 3 years old iMac with snow leopard (10.6.6)
Thanks for the help!

I have the same exact problem!!! I cannot use the program! And there is no software update available.
What can we do? At this point iMovie is unusable. I have tried deleting all plist files to no avail.
Software update please?

http://i.imgur.com/FLLd0.png
same thing happens when i restore to default, and then try to restore again from my backup.
i am frastrated. i have a serious headache. 5 hours of trying to upgrade. i really want to CRY (really).
i REALLY need ALL of my information. including contacts, calendar and internal information of application i bought (like 2Do, awesome note etc.). i can not afford myself losing all of this information. i have no other backup. this information worth more then 5k $ to me.
what can i do? i need HELP.
only thing it let me restore is my music.

Try moving the existing backup file to a safe location so that iTunes has to create an entire new file. If you get a successfull backup you can delete the moved backup. The backup is located:
iTunes places the backup files in the following places:
Mac: ~/Library/Application Support/MobileSync/Backup/
Windows XP: \Documents and Settings\(username)\Application Data\Apple Computer\MobileSync\Backup\
Windows Vista and Windows 7: \Users\(username)\AppData\Roaming\Apple Computer\MobileSync\Backup\
Note: If you do not see the AppData or Application Data folders, you may need to show hidden files (Windows XP, Windows Vista, Windows 7), or iTunes may not be installed in the default location. Show hidden files and then search the hard drive for the Backup directory.
