Mac OS Yosemite 10.10.1 fails to boot

I am running OS 10.10.1 on Mac Pro Early 2009. This morning all running programs including Finder froze. All i could do was Quit or force-quit the running programs and shut down. Then the computer failed to boot. I was able to boot in Safe Mode. But any attempt for normal boot failed.
Since i have Boot Camp, I tried booting to the Disk Startup Manager (pressed Option key). I got the 3 options -- (1) Mac OS; (2) Windows; and (3) Recovery. But after I selected either Windows or Mac OS and the arrow moved to my selected option, nothing happened when i clicked the "arrow" button. I could click it many times but the screen remained frozen till I powered off the computer.
Strangely, when I held down the Command key by itself the computer started normally. But subsequent all attempts to boot normally failed again.
Any suggestions?
i will greatly appreciate any help. Thank you all in advance.

Boot into the recovery partition and select Disk Utility from the 4 option menu.
Run Disk Utility>First Aid, Verify and Repair.
If the disk cannot be repaired an new HDD will have to installed.
Ciao.

Mac OS 9.2.1 CD fails to boot on PowerBook G4 running Mac OS 10.3.9

I reformatted a friend's PowerBook G4 and installed Mac OS 10.3.9 with no problem. They have a few Classic applications they need to use, but I can't get the Mac OS 9.2.1 CD to boot so i can install it. The CD is bootable, because it says so right on the disc (white disc with orange "9"). I tried setting the startup disk to the CD drive, but that drive won't show up in the startup disk preferences. I've also tried installing from the desktop while booted into Mac OS X, but the OS 9 installer will not install. Any ideas?
PowerBook G4 Mac OS X (10.3.9) 1.25 GHz; 512 MB RAM

Hi, Temporos. Most Powerbook G4 models aren't able to boot into OS 9.anything, regardless of the disc being used.
All Titanium PB G4s, which have two separate hinges and most of their ports on the back panel between the hinges, are bootable into some version of OS 9. Some of them require the model-specific version of OS 9.2.2 that was shipped on the discs that came with them. There is no other source for a bootable OS 9.2.2 on those models.
The many different Aluminum PB G4 models (12", 15" and 17"), which all have a single continuous hinge running all the way across the back and all their ports on the side panels, can't boot into any version of OS 9. The discs that were shipped with them include installers for Classic, i.e. a non-bootable installation of OS 9 that can be used to run OS 9-based apps in OS X.
Whether or not your Powerbook can boot to an OS 9.2.1 retail installer disc is not dependent on having OS 9 drivers installed on the hard drive. Even without those drivers installed, a Powerbook that is capable of booting to a retail 9.2.1 disc will do so, if the disc and the PB's optical drive are in working order. But if the PB can't boot to that disc, nothing you can do will change that.
Please identify your PB G4 model precisely. Then we'll know how to advise you.

My HP Photosmart 5510 won't scan photos to file on my Mac running Yosemite

I keep getting an error message that the scan failed every time I try to scan a photo. I've downloaded the latest driver via the Apple App Store. I've restarted both computer and printer. Help!
This question was solved.

Hi @JaneCat,
Welcome to the HP Forums!
I understand that you cannot scan photos from your HP Photosmart 5510 to a file on your Mac running Yosemite. I am sorry to hear this, but I am happy to help!
I would recommend downloading the full feature software and drivers from our website, HP Photosmart 5510 e-All-in-One Printer Full Feature Software and Drivers, as it is compatible with Mac OS X Yosemite.
If you are still having issues, I would also recommend this scanning guide, A 'No computer found' Message Displays during Scanning. Then follow the steps for the section that says it is for, Mac OS X v10.6 Snow Leopard, OS X v10.7 Lion, OS X v10.8 Mountain Lion, or OS X v10.9 Mavericks. As these steps will still work on Mac OS X Yosemite.
I would also see this how to scan guide, Scanning with the Full Feature HP Software in OS X v10.10 Yosemite.
Hope this information is helpful, and thank you for posting!

I have 10.6 8 Sno Leopard and trying to download yosemite by it keeps failing. Are there other operating systems in between that need to be installed first?

I have 10.6 8 Snow Leopard and trying to download yosemite by it keeps failing. Are there other operating systems in between that need to be installed first?

Before embarking on a major OS upgrade, it would be wise, advisable and very prudent if you backup your current system to an external connected and Mac formatted Flash drive OR externally connected USB, Thunderbolt or FireWire 800, Mac formatted hard drive. Then, use either OS X Time Machine app to backup your entire system to the external drive OR purchase, install and use a data cloning app, like CarbonCopyCloner or SuperDuper, to make an exact and bootable copy (clone) of your entire Mac's internal hard drive. This step is really needed in case something goes wrong with the install of the new OS or you simply do not like the new OS, you have a very easy way/procedure to return your Mac to its former working state.
Then, determine if your Mac meets ALL minimum system install requirements.
To install OS X 10.8 Mountain Lion, 10.9 Mavericks (free upgrade, but currently unavailable) or OS X 10.10 Yosemite (currently available free upgrade) you need one of these Macs:
OS X 10.8 Mountain Lion purchased emailed download code here.
http://store.apple.com/us/product/D6377Z/A/os-x-mountain-lion
iMac (Mid-2007 or later)
MacBook (13-inch Aluminum, Late 2008), (13-inch, Early 2009 or later)
MacBook Pro (13-inch, Mid-2009 or later),
MacBook Pro (15-inch or 17-inch, Mid/Late 2007 or later)
MacBook Air (Late 2008 or later)
Mac mini (Early 2009 or later)
Mac Pro (Early 2008 or later)
Xserve (Early 2009)
Your Mac also needs:
OS X Mountain Lion, Lion, or Snow Leopard v10.6.8 already installed
2 GB or more of memory (I strongly advise, at least, 4 GBs of RAM or more)
8 GB or more of available space
Next,
If you run any older Mac software from the earlier PowerPC Macs, then none of this software will work with the newer OS X versions (10.7 and onward). OS X Snow Leopard had a magical and invisible PowerPC emulation application, called Rosetta, that worked seamlessly in the background that still allowed older PowerPC coded software to still operate in a Intel CPU Mac.
The use of Rosetta ended with OS X Snow Leopard as the Rosetta application was licensed to Apple, from a software company called Transitive, which got bought out, I believe, by IBM and Appe could no longer secure their rights to continue to use Rosetta in later versions of OS X.
So, you would need to check to see if you have software on your Mac that maybe older than, say, 2006 or older.
Also, check for app compatibilty here.
http://roaringapps.com/
If you have any commercial antivirus installed and/or hard drive cleaning apps installed on your Mac, like MacKeeper, CleanMyMac, TuneUpMyMac, MacCleanse, etc. now would be a good time to completely uninstall this apps by doing a Google search to learn how to properly uninstall these types of apps.
These types of apps will only cause your Mac issues later after the install of the new OS X version and you will have to completely uninstall these types of apps later.
Once you have determined all of this, you should be able to find the latest versions of OS X by clicking on the Mac App Store icon in the OS X Dock and then login to the Mac App Store using your Apple ID and password and if you purchased a download code, input that code.
You can then begin the download and installation process of installing the newer versions of OS X from the Mac App Store.

I am trying unsuccessfully to download CC 2014 onto a new Mac with Yosemite 10.10.2, newest version.

I am trying to download CC 2014 onto a new Mac with Yosemite 10.10.2, newest version, but it will not hold the internet connection for more than a few minutes so the download keeps failing. Can anybody help please. All the other devices in my house are working well, no internet problems at all. Mavericks on my MacBook is fine with the internet. I have CC and LR5.5 on it, I have a subscription.

<Edited by Host>

Take each of these steps that you haven't already tried. Stop when the problem is resolved.
To restart an unresponsive computer, press and hold the power button for a few seconds until the power shuts off, then release, wait a few more seconds, and press it again briefly.
Step 1
The first step in dealing with a startup failure is to secure the data. If you want to preserve the contents of the startup drive, and you don't already have at least one current backup, you must try to back up now, before you do anything else. It may or may not be possible. If you don't care about the data that has changed since the last backup, you can skip this step.
There are several ways to back up a Mac that is unable to start. You need an external hard drive to hold the backup data.
a. Start up from the Recovery partition, or from a local Time Machine backup volume (option key at startup.) When the OS X Utilities screen appears, launch Disk Utility and follow the instructions in this support article, under “Instructions for backing up to an external hard disk via Disk Utility.” The article refers to starting up from a DVD, but the procedure in Recovery mode is the same. You don't need a DVD if you're running OS X 10.7 or later.
b. If Step 1a fails because of disk errors, and no other Mac is available, then you may be able to salvage some of your files by copying them in the Finder. If you already have an external drive with OS X installed, start up from it. Otherwise, if you have Internet access, follow the instructions on this page to prepare the external drive and install OS X on it. You'll use the Recovery installer, rather than downloading it from the App Store.
c. If you have access to a working Mac, and both it and the non-working Mac have FireWire or Thunderbolt ports, start the non-working Mac in target disk mode. Use the working Mac to copy the data to another drive. This technique won't work with USB, Ethernet, Wi-Fi, or Bluetooth.
d. If the internal drive of the non-working Mac is user-replaceable, remove it and mount it in an external enclosure or drive dock. Use another Mac to copy the data.
Step 2
If the startup process stops at a blank gray screen with no Apple logo or spinning "daisy wheel," then the startup volume may be full. If you had previously seen warnings of low disk space, this is almost certainly the case. You might be able to start up in safe mode even though you can't start up normally. Otherwise, start up from an external drive, or else use the technique in Step 1b, 1c, or 1d to mount the internal drive and delete some files. According to Apple documentation, you need at least 9 GB of available space on the startup volume (as shown in the Finder Info window) for normal operation.
Step 3
Sometimes a startup failure can be resolved by resetting the NVRAM.
Step 4
If a desktop Mac hangs at a plain gray screen with a movable cursor, the keyboard may not be recognized. Press and hold the button on the side of an Apple wireless keyboard to make it discoverable. If need be, replace or recharge the batteries. If you're using a USB keyboard connected to a hub, connect it to a built-in port.
Step 5
If there's a built-in optical drive, a disc may be stuck in it. Follow these instructions to eject it.
Step 6
Press and hold the power button until the power shuts off. Disconnect all wired peripherals except those needed to start up, and remove all aftermarket expansion cards. Use a different keyboard and/or mouse, if those devices are wired. If you can start up now, one of the devices you disconnected, or a combination of them, is causing the problem. Finding out which one is a process of elimination.
Step 7
If you've started from an external storage device, make sure that the internal startup volume is selected in the Startup Disk pane of System Preferences.
Start up in safe mode. Note: If FileVault is enabled in OS X 10.9 or earlier, or if a firmware password is set, or if the startup volume is a software RAID, you can’t do this. Post for further instructions.
Safe mode is much slower to start and run than normal, and some things won’t work at all, including wireless networking on certain Macs.
The login screen appears even if you usually log in automatically. You must know the login password in order to log in. If you’ve forgotten the password, you will need to reset it before you begin.
When you start up in safe mode, it's normal to see a dark gray progress bar on a light gray background. If the progress bar gets stuck for more than a few minutes, or if the system shuts down automatically while the progress bar is displayed, the startup volume is corrupt and the drive is probably malfunctioning. In that case, go to Step 11. If you ever have another problem with the drive, replace it immediately.
If you can start and log in in safe mode, empty the Trash, and then open the Finder Info window on the startup volume ("Macintosh HD," unless you gave it a different name.) Check that you have at least 9 GB of available space, as shown in the window. If you don't, copy as many files as necessary to another volume (not another folder on the same volume) and delete the originals. Deletion isn't complete until you empty the Trash again. Do this until the available space is more than 9 GB. Then restart as usual (i.e., not in safe mode.)
If the startup process hangs again, the problem is likely caused by a third-party system modification that you installed. Post for further instructions.
Step 8
Launch Disk Utility in Recovery mode (see Step 1.) Select the startup volume, then run Repair Disk. If any problems are found, repeat until clear. If Disk Utility reports that the volume can't be repaired, the drive has malfunctioned and should be replaced. You might choose to tolerate one such malfunction in the life of the drive. In that case, erase the volume and restore from a backup. If the same thing ever happens again, replace the drive immediately.
This is one of the rare situations in which you should also run Repair Permissions, ignoring the false warnings it may produce. Look for the line "Permissions repair complete" at the end of the output. Then restart as usual.
Step 9
If the startup device is an aftermarket SSD, it may need a firmware update and/or a forced "garbage collection." Instructions for doing this with a Crucial-branded SSD were posted here. Some of those instructions may apply to other brands of SSD, but you should check with the vendor's tech support.
Step 10
Reinstall the OS. If the Mac was upgraded from an older version of OS X, you’ll need the Apple ID and password you used to upgrade.
Step 11
Do as in Step 9, but this time erase the startup volume in Disk Utility before installing. The system should automatically restart into the Setup Assistant. Follow the prompts to transfer the data from a Time Machine or other backup.
Step 12
This step applies only to models that have a logic-board ("PRAM") battery: all Mac Pro's and some others (not current models.) Both desktop and portable Macs used to have such a battery. The logic-board battery, if there is one, is separate from the main battery of a portable. A dead logic-board battery can cause a startup failure. Typically the failure will be preceded by loss of the settings for the startup disk and system clock. See the user manual for replacement instructions. You may have to take the machine to a service provider to have the battery replaced.
Step 13
If you get this far, you're probably dealing with a hardware fault. Make a "Genius" appointment at an Apple Store, or go to another authorized service provider.

FW CS6 compatible with Mac OS Yosemite?

Is FW CS6 compatible (without issues) with Mac OS Yosemite?

Photoshop and Indesign worked directly after the upgrade. I had some trouble getting Illustrator to work:
I had problems with Adobe Illustrator CS3 and Yosemite. After the upgrade I installed Java for OS X 2014-001, as suggested by others. This seemed to work (sometimes) but when I opened Illustrator for the 2nd time it failed to open. Illustrator opened without crashing, but it did not show any menus, if I opened an .ai file the file did load and show on the screen, but I could not click on the window (unresponsive). Essentially this made Illustrator useless. I tried the following:
Re-installation
Install Java for OS X 2014-001
Cleaning font cache
Checking permissions
Installing other versions of Java (both JRE and JDK)
Nothing seemed to help. Until finally 15 minutes ago I found the solution by accident:
Open System Preferences > Java
Wait for the Java Control Panel to load
Open Adobe Illustrator (while keeping the Java Control Panel window open)
Hope this will also help others!

I have just updated Acrobat to version 10.1.13. I am using a MAC Running Yosemite. When I try to scan a document, after the printer scans Adobe Acrobat quits and I get an unexpected closure error.

I have just updated Acrobat to version 10.1.13. I am using a MAC Running Yosemite. When I try to scan a document, after the printer scans Adobe Acrobat quits and I get an unexpected closure error. I am running Mac OS 10.10.1. This only started happening when I installed the update of Adobe Acrobat.

Hi MEW1,
Is the printer connected wirelessly or wired?
Go to Preferences and under categories go to > Convert to Pdf then select the Image Capture and then hit ok button.
Close Acrobat and then relaunch it and see if it helps you while you do scanning.

How can I delete the files .DS_store in Mac OS Yosemite?

How can I delete the files .DS_store in Mac OS Yosemite?

The .DS_Store file is normal. It holds certain settings related to the folder it is found in. Removing these files is futile, as they will come back, as you have observed.
If you are seeing them on your Mac, that means you have changed settings so that your Mac is showing invisible files in the Finder. To reverse that, run the following command in the Terminal:
defaults write com.apple.finder AppleShowAllFiles NO
This will hide them, and any other invisible files, from view.
If you are seeing them on a Windows machine, just ignore them. They're not doing any harm.
If you found a Terminal command that is supposed to stop them from being created, I would be extremely skeptical as to the wisdom of running it.
