Stuck In A Groove Mac OS

If you have ever used a Windows Operating System (especially windows 98, XP, and 2000 series OS) then you surely know what a “Blue screen of Death” or a “Blue screen of Doom” is! Every time you encounter this screen, you know there is something seriously wrong with either the hardware or the software. Similarly, we have a “Gray Screen of Death” for the Mac OS X which I didn’t know until I encountered it.

Mac restart refers to the process where after the installation of new updates is finished, the system shuts itself down and starts again to reflect the changes and improvements in the Mac OS present in your device. A lot of times due to issues during installation of the update or due to bugs, your Mac may get stuck during this point. Free download Groove Agent Groove Agent for Mac OS X.

Mac OS X Gray Screen of Death

I recently upgraded my Mac Mini from 10.9.3 Mavericks to 10.9.4. After the upgrade, the system seemed to be quite sluggish and almost hanged at times!!. The next day after the upgrade I was working with Eclipse IDE and Safari window was open, the system hanged!, I waited for some time (though maybe some Build activity was consuming up the resources) but nothing seemed to be happening, so I did a Forced Restart by holding down the Start button.

After restarting my Mac, I could see a Gray Screen with the Apple logo as usual, but there was also a Gray Color Spinner and a Progress Bar which we normally see when system restarts after upgrades. The Spinner was stuck in a loop for a long time.

Mac OS X Grey Color Screen with Spinner and Progress Bar

Just a few minutes later (25% completion of the progress bar) the Monitor went black and the Mac turned off. I did a restart again, but it was all the same, Gray Spinner and the Progress-Bar reaching unto 25% and the screen goes blank. Now I knew that I was in big trouble. First thing I realized that I didn’t do my weekly backup! If it turns out to be an OS crash or HDD failure I would lose all my data.

Recovery & Troubleshooting Mac Mini/Mac Book

I did some google search and found out that many people were facing this issue. Everything pointed out that I could be that the Hard-disk is dying.

It took me 2 days to restore my Mac Mini and to get all my data back. I am putting down all my experience here so that someone may find it useful.

Apple Startup Key Combinations (Intel-based Macs)

Note : Before we talk about this a really important note if you have a wireless Apple keyboard ( or maybe any other brand wireless keyboard) boot key combinations won’t work (though it may work for newer versions, mine is 2012 make). You have to get a wired keyboard preferably apple one ( i borrowed a Microsoft USB keyboard but it too did work, then I got a Logitech keyboard and it did work)

Initial Troubleshooting Steps

This may sound weird, but it does works sometimes. Turn off your PC and remove all connections. USB devices, HDMI cables, Mouse & Keyboard, etc, and the power cords. Reconnect your system after 10-20 mins with minimum peripherals ( keyboard and mouse ) and see if things get back to normal.

Force Shut down

Press and hold the Power Button on your Mac Mini ( or equivalent on your Mac Book, Mac Book Air) for 5-10 secs. Note that if you do a Force Shutdown when your system is running you may lose all your unsaved data, but not in our case as the OS is not getting loaded on the first-hand :P

Resetting PMU :

Power Management Unit (PMU) is a chip responsible for Mac's power management i.e. controlling HDD spin down, sleep and wake up and devices that are attached to the computer. Resetting PSU can resolve hardware failures related to power management. Resetting PMU also resets PRAM settings and it should be tried only after none of the below works,

How to do a PMU reset :

1. Unplug all cables, USB, HDMI and even the power button. 2. Wait for some time (10 secs or more) 3. Plugin the power cord simultaneously press and hold the power button. 4. Release the power button and press it again to start up for mac Mini.

Safe Mode Booting

You must always try doing a Safe Mode Boot as the first troubleshooting step, for Mac try doing a safe mode boot by holding down Shift Key during boot time (when you hear the chime sound) until you see an Apple Logo and a spinner and a progress bar. I was not able to hear the chime. So had to reset the NVRAM/PRAM.

NVRAM is a memory area that stores certain data related to a system that is persistent even after shutdown. Information that NVRAM/PRAM stores are, Screen resolution that you may have set, the Speaker Volume, Startup disk to be selected and Kernel panic information.

Resetting NVRAM/PRAM settings :

I followed these steps and I could head the chime sound. But it didn’t resolve the issue, nor I was able to start my Mac in Safe Mode.

Apple Hardware Test

Press D Button when you hear the Chime on boot to start Apple Hardware Test (AHT). Any hardware abnormalities can be detected ( read more http://support.apple.com/kb/HT1509). I got an AHT screen where you have to select your language and then perform hardware tests, I start the test and I waited around 3-4 hours until I realized that I was stuck and nothing was happening. If you're lucky you may get to know what the issue is performing this test.

Boot form CD/DVD or USB Drive

If you have a CD or DVD ROM and a Mac OS X setup disc ( in my case, as I have a MAC Mini I do not have a CD ROM ) you can hold C during startup to boot from CD/DVD. Make sure that you insert the Disc before you perform CD startup.

Similarly if you have a bootable USB drive with Mac OS X setup you can boot the system by holding down C button during boot.

Booting in Single-User Verbose mode

Start your Mac and press Command + V when you hear the chime. Now when the system boots you will not see the Gray screen, instead you will see a black screen with Text. This is a really helpful boot option and it really helped me to know what was the exact problem. The best part is you get access to the command line, so backup is possible.

Here are the logs :

disk0s2: I/O error! : Macintosh HD could not be Verified!! was surely related to hardware i.e Hard Disk to be more specific.

This error is an indicator that the HardDisk is dying.

fsck is a Linux/Unix command used to check and repair Linux/Unix file systems. Mac OS X includes fsck utility as a command-line utility which can be used by entering single-user mode using (Command + S at startup)

fsck is used at reboot to check to do a filesystem check. As soon as your system is booted in Verbose mode in Single user mode you would see the following.

Output :

Once you get the # command-line prompt :

Type the following command :

-y: Assume a yes response to all questions asked by fsck this should be used with great caution as this is a free license to continue after essentially unlimited trouble has been encountered.

Output : https://diamondsmpepromocodesblackdeposit-geniuscasino.peatix.com.

If everything is fine you will get This volume Macintosh HD appears to be OK. , else you will get disk0s2: I/O error. https://extranewline220.weebly.com/sako-sushi-yuki-mac-os.html. The volume Macintosh HD could not be verified completely.

You can mount an internal file system (USB disk) using /sbin/mount/.

-uw: It is used to change the status for the already mounted file system. You can change a read-only file system to read-write and vice versa.

Now plug in your USB stick. As soon as you insert your USB disk you get a message on the prompt that it has been installed.

:/ root# USBMSC Identifier (non-unique) : 2828472829C8192929 0x2493 0x304 0x2939

Now let's check all disks that are mounted.

To list down all the attached disks.

all disk0 devices are mostly the internal disks with file system HFS, so disk1s1 must be the external disk i.e our USB disk, let's check the file type.

Output : msdos

so we now confirm that it is a USB disk named as disk1s1,

Now we need to make a mount point, a dir where we will mount our USB drive.

Now let's mount the USB to my mount point,

Now that our USB stick is mounted, let verify that it has been mounted correctly by running the ls command.

Output :

Now that you have the access to the external Drive/HHD/USB you can simply copy all your important files from the Mac and once you are done you can go for a fresh installation.

Once you have copied all your files you can unmount the USB drive using the command,

Mac OS X Internet Recovery mode

Press Command + R button during startup and you will be taken to Recovery Mode, wait until you see a gray screen with the apple logo. (Note: this option is available for Macs that were shipped with Mac OS X Lion or later. Some Mac’s may require EFI BootROM update for this command/feature)

I got a screen where i was asked to select my Wifi Connection and set the password. Once I did so, I was taken to internet recovery mode, a black-and-white globe appears spinning and reads,

Starting Internet Recovery. This may take a while. Depending upon your internet connection speed it will download Utility data.

If everything goes well you will be able to see Mac OS X bar and utility window. Options like

Run Disk Utility to check if the disk is in good health. As I had recovered my data I did a format of my disk and did a fresh install of Mac OS X Lion. The setup will be downloaded from the internet after checking that you have a genuine account.

Finally my system was back running Mac OS X Lion (10.8). I was able to restore all my purchases and other apps via App Store and even did upgrade to Mac OS X 10.10 Yosemite and things seem to be working fine.

To get the latest features and maintain the security, stability, compatibility, and performance of your Mac, it's important to keep your software up to date. Apple recommends that you always use the latest macOS that is compatible with your Mac.

Learn how to upgrade to macOS Big Sur, the latest version of macOS.

Check compatibility

If a macOS installer can't be used on your Mac, the installer will let you know. For example, it might say that it's too old to be opened on this version of macOS, or that your Mac doesn't have enough free storage space for the installation.

To confirm compatibility before downloading, check the minimum requirements for macOS Catalina, Mojave, High Sierra, Sierra, El Capitan, or Yosemite. You can also find compatibility information on the product-ID page for MacBook Pro, MacBook Air, MacBook, iMac, Mac mini, or Mac Pro.

Make a backup

Before installing, it’s a good idea to back up your Mac. Time Machine makes it simple, and other backup methods are also available. https://crapsisseedslotswhatabetawivfinplace.peatix.com. Learn how to back up your Mac.

Download macOS

It takes time to download and install macOS, so make sure that you're plugged into AC power and have a reliable internet connection.

Safari uses these links to find the old installers in the App Store. After downloading from the App Store, the installer opens automatically.

  • macOS Catalina 10.15 can upgrade Mojave, High Sierra, Sierra, El Capitan, Yosemite, Mavericks
  • macOS Mojave 10.14 can upgrade High Sierra, Sierra, El Capitan, Yosemite, Mavericks, Mountain Lion
  • macOS High Sierra 10.13 can upgrade Sierra, El Capitan, Yosemite, Mavericks, Mountain Lion

Safari downloads the following older installers as a disk image named InstallOS.dmg or InstallMacOSX.dmg. Open the disk image, then open the .pkg installer inside the disk image. It installs an app named Install [Version Name]. Open that app from your Applications folder to begin installing the operating system.

  • macOS Sierra 10.12 can upgrade El Capitan, Yosemite, Mavericks, Mountain Lion, or Lion
  • OS X El Capitan 10.11 can upgrade Yosemite, Mavericks, Mountain Lion, Lion, or Snow Leopard
  • OS X Yosemite 10.10can upgrade Mavericks, Mountain Lion, Lion, or Snow Leopard

Install macOS

Follow the onscreen instructions in the installer. It might be easiest to begin installation in the evening so that it can complete overnight, if needed.

If the installer asks for permission to install a helper tool, enter the administrator name and password that you use to log in to your Mac, then click Add Helper.

Please allow installation to complete without putting your Mac to sleep or closing its lid. Your Mac might restart, show a progress bar, or show a blank screen several times as it installs macOS and related firmware updates.
