fixed : MacBook Pro hangs during final stage of macOS startup

Question :

I have macOS 10.14 Mojave installed on my MacBook Pro ‘Mid 2012’, but every time I try to start up my Mac, it hangs when the progress bar (on the white startup screen with the Apple logo) is at 99%…

On the TechRadar-website I found some startup key-combos to try : https://www.techradar.com/how-to/computing/apple/how-to-use-os-x-boot-options-to-troubleshoot-your-mac-1305645

I have tried the following, but it didn’t help :

  • restarting my MacBook
  • zapping the PRAM / NVRAM
  • running Disk First Aid in Recovery Mode
  • running Disk First Aid from another Mac while in Target Mode
  • reinstalling macOS Mojave from Recovery Mode
  • reinstalling macOS Mojave from a USB installer

So far, no problems where found, but the exact same problem keeps occuring :

When I startup my MacBook Pro, the progress bar goes quickly to 50%, then slows down but still keeps progressing up to 99% or even 100% and then hangs…

What can I do to solve this ?

 

Answer :

You have already tried most of the options that usually give success when you encounter these types of problems, so you have little options left to choose from.

The first thing to try would be ‘Verbose Mode’ so you will be able to figure out what problems are encountered during startup :

  • shut down you Mac using the power button
  • startup your Mac in Verbose Mode by pressing the [CMD]+[V] keycombo on your keyboard during startup
  • now, your Mac starts up without a GUI (Graphic User Interface) but just displays lines of code (like in the Terminal.app and Console.app)
  • note that you might see a screen of code flashing by and than face your regular inlog screen… if so, just login and you will get to the Console-like black screen with white lines of code…
  • wait for the lines of code to halt and see what error messages are displayed in the final lines of code
  • if the error is “too many corpses being created”, use the solution outlined below (additional error terms are “Process”, “crashed:” and “opendirectoryd.”)
  • if you get any different error message : lookup the error message and the solution on the internet

The solution to the “too many corpses being created” startup-error :

  • shut down your Mac using the power button
  • startup your Mac in Recovery Mode by pressing the [CMD]+[R] key combo on your keyboard during startup
  • if FireVault is on, mount the HardDisk by clicking Disk Utility.app and then typing your password
  • then, go to Utilities in the top menu bar and click Terminal in the pulldown menu
  • in Terminal.app type this line of code (in which “Macintosh\ HD” is replaced by the name your have given your HardDisk ; the default name is “Macintosh HD”, and note that all spaces in the name of your HardDisk should be replaced by “\ ” (a backslash + a space) when typing these lines of code) :

cd /Volumes/Macintosh\ HD/var/db/caches/opendirectory

  • then press the [Enter]-key to run the code
  • when the cursor returns on the very next line you’re good, if you get an extra line in between, you’ve run into an error (e.g. “command not found” usually means you mistyped something, so you should just try again ; if you forgot to replace the space in your HardDisk’s name by “\ “ you’ll also get an error and you should just try again)
  • on the next line, type this :

mv ./mbr_cache ./mbr_cache-old

  • then press the [Enter]-key
  • when the cursor returns on the very next line you’re good
  • again, if you get an extra line in response, you’ve made an error and trying again with greater accuracy will probably solve it…
  • then, exit Terminal.app by pressing the [cmd]+[Q] key-combo
  • then restart your Mac by clicking on the Apple-icon top left in the top menu bar and clicking “Restart” from the pull down menu
  • now your Mac should startup without problems
  • note that the first startup will take a little longer, as all system settings need to be rebuilt

That’s it !

enjoy 😉

fixed : Adobe Creative Cloud Application Manager hangs at “Please wait for a moment”

Question :

I just purchased a new Student&Teacher license code for Adobe Creative Cloud, and I even though I can see on the Adobe-website that the new subscription is active on my AdobeID, I cannot use any Creative Cloud application on my Mac, because when I startup Photoshop CC (or Illustrator CC or InDesign CC), the Adobe Aplication Manager app is automatically run, the Creative Cloud window opens, it flashes and then “Please wait for a moment” is displayed and the clock keeps spinning… and spinning… and spinning…

Quitting the Adobe Application Manager app and trying again give the same result, and even restarting my Mac with all apps refreshed gives the same error… the Creative Cloud window just hangs on “Please wait for a moment”…

How can I fix this ?

 

Answer :

The first part of the solution is to make sure that your Creative Cloud subscription is active :

  • go to the Adobe-website
  • login with your AdobeID and password
  • then click on “Manage Account”
  • then, login again using your AdobeID and password
  • then, check at “subscriptions and products” if your Creative Cloud subscription is listed

If it’s not listed, use the Redemption Code that you got after purchasing your Creative Cloud renewal to (re)activate your CC-subscription.

If your CC-subscription is active, proceed to the second part of the solution :

  • on your Mac, click on the Creative Cloud logo (that looks like a cloud in the form of the number 8 that has fallen over) in the top bar of the screen, on the right side
  • there, it will say that the Application Updater or Application Manager app itself needs to be updated
  • click on update
  • wait for the update to finish
  • then a list of all individual CC-apps with updates available is displayed
  • click on “update all”
  • wait for the update to finish

That’s it – now you can startup any Adobe app and it will properly run.

enjoy !

 

fixed : SPL-C ERROR page printed by Samsung printer

Question :

when I tried to print to my Samsung printer via my Home-network today, the spooling process was very slow, then hung, and then a printed page rolled out of the printer with this text only :

SPL-C ERROR – Disconnected from Host. Please check the connection and try again.

POSITION : 0x3dc5 (252981)

SYSTEM : src_5.59/os_hook

LINE : 1978

VERSION : SPL-C 5.59 05-04-2012

So I restarted the printer, made sure there wasn’t any paper stuck, and tried again. This time I the spooling process was very slow again, hung again, and a similar page rolled out of the printer with this text :

SPL-C ERROR – Disconnected from Host. Please check the connection and try again.

POSITION : 0x15ea5 (89765)

SYSTEM : src_5.59/os_hook

LINE : 1978

VERSION : SPL-C 5.59 05-04-2012

So despite the difference in ‘position’, the problem remained.

What can I do to solve this ?

 

Answer :

This seems to be a weird bug popping up on some Samsung printers connected to Macs once in a while. To solve this problem, do this :

  • quit any printing jobs that are active
  • shut down the printer (take the power cable out)
  • on your Mac, go to System Settings > Printers & Scanners
  • there, delete the problematic printer (by selecting it in the list and clicking the minus-button)
  • then, restart your Mac
  • switch the printer back on (reconnect the power cable)
  • login on your Mac
  • go to System Settings > Printers & Scanners
  • add the printer to the list again (by clicking on the plus-button, and selecting it from the printers found)
  • then close the System Preferences and try printing your document again

That’s it !

fixed : “Your iPad could not be activated”/”Activation server temporarily unavailable”-error

Question :

After my iPad tried to update to iOS 9.3.x (this also goes for iOS 11.2.x) last night, I had to re-enter my AppleID and now I’m getting a blank page with only this error message :

“Your iPad could not be activated because the activation server is temporarily unavailable. Try connecting your iPadto iTunes to activated it or try again in couple of minutes.”

But even if I wait a couple of minutes or even an hour, and try again, I get stuck with this same message…

How can I fix this ?

 

Answer :

Apple Support has a tutorial on how to fix this, but a lot of times that doesn’t work :

If you can’t activate your iPad 2 (GSM model) after you update to iOS 9.3

If you can’t figure out how to do that, or you’ve tried and it doesn’t work for you, try this :

  • if you have an iPad with a GSM SIM-card installed, make sure you have the SIM’s 4-digit PIN-code at hand, then pop the SIM-card out using a bended paperclip or the official tool that’s comes with every iPhone and every SIM-card enabled iPad
  • then, on your Mac, go to Apple-icon (top-left in the menu bar) –> system Preferences –> iCloud
  • in the window that opens, see what eMail-address is listed under your name ; make sure to remember that eMail-address : this is your iCloud-account name (which might be different from your AppleID or iTunes Store-account name)
  • then click on “Account Details” and type the password that is connected to your iCloud-account name
  • if a new window opens, remember this password and close the window
  • if you get an error message that your password is incorrect, make sure you find the password and try again (you can try several times, but if you get a warning that you have only a limited amount of attempts remaining, stop immediately !! and skip this step)
  • now return to your iPad and do a reset by pressing the Home-button (physical button below the screen) and the Power-button (physical button on the right edge or top edge) simultaneously until the screen goes black and the white Apple logo appears
  • now, proceed though the following screens as you normally would until you are asked to enter your Account Name : there you should enter the eMail-address that is your iCloud-account name and the corresponding password
  • if this works, don’t forget to put the Sim-card back into your iPad and you’re done
  • if you happen to run into the Activation Server error page again before you get to the page where you should enter your Account Name, do this :
    • open the AppStore-app on your Mac
    • make sure you have installed all official Apple updates (especially iTunes)
    • connect your iPad directly (so without USB-hubs) to your Mac using the iPad-to-USB-cable
    • on your Mac, open iTunes
    • then do the reset on you iPad agian, simultaneously pressing the Home- and Power-buttons until the Apple logo appears
    • now iTunes (on your Mac) should detect your iPad
    • if it doesn’t, try the reset again
    • if it does, see if you can go trough all setup screen on your iPad
    • if you are unable to do so, go to iTunes on your Mac
    • if a message appears you need to unlock your iPad, type the screen unlock code on your iPad
    • if a “Trust this iPad ?” message appears on your Mac, click “Trust”
    • if a “Trust this Mac ?” message appears on your iPad, click “Trust”
    • now you see a small button with an iPad on it next to the Music/Films/etc.-pulldown menu ; click on it
    • in the next window, you should now be able to initiate the iOS-update of your iPad from your computer
    • then wait for the update to complete
  • afterwards, do not forget to put the SIM-card back into your iPad

Good luck & enjoy 😉

fixed : macOS Sierra downloaded but installer won’t run

Question :

Since the latest version of OSX (entitled “macOS Sierra) has been yesterday, I wanted to install it on my Mac. I clicked on “download” in the Mac AppStore and  the download started ; on the dedicated product page I could see the status bar filling up and finally stating “downloaded”… but then, nothing happened…

The download wouldn’t install…

I re-checked if macOS Sierra does support my Mac, it does. So I tried restarting the AppStore-app, I tried logging out my iCloud/AppStore-account & than logging back in, I tried rebooting my Mac, I tried rebooting in SafeMode, I tried FirstAid in the Disk Utility app, I tried clicking 10 times on the “downloaded” button repeatedly, I tried installing the DeBug-menus & cleaning the AppStore cache, I tried deleting the hidden AppStore downloads folder… and I tried various command line solutions found online in the Terminal app… nothing helped… I am still stuck with the button under the macOS Sierra icon saying “downloaded”… and nothing happens…

What can I do ?

 

Answer :

You are probably not (really) going to like this answer, because this will set you back hours & hours, in which you can’t use your Mac ; but it’s the only way known to solve this, and you need to have a recent TimeMachine backup (or alike) for it :

  1. shut down your Mac
  2. disconnect all cables  from your Mac (except your keyboard & mouse if you haven’t got a MacBook)
  3. restart your Mac, and be quick to press the [CMD]+[R] key-combo during startup (your Mac will now start up in Recovery Mode)
  4. in the “OS X Utilities” window that appears, select Restore From TimeMachine Backup and click Continue
  5. in the next “Restore Your System” window, click Continue
  6. now first make sure that your Mac can connect to your TimeMachine-harddisk by plugging in it’s USB-cable, plugging in your Ethernet-network-cable or connect to your WiFi router
  7. then select the hard drive that has your TimeMachine backups on it and click Continue
  8. in the next window, make sure you select the most recent backup that is from before you tried to download macOS Sierra ; only if you’re sure you’ve selected the right backup, proceed and click Continue
  9. now wait (or do something more useful in the mean time) and wait and wait ; this is going to take hours and hours ; putting back a TimeMachine backup this way will go a a speed of about 30BG per hour, so if your hard drive is 500GB it may take you about 15 hours (yes, an entire night and an entire morning…)
  10. finally, once the TimeMachine backup-reinstall is done, your Mac will restart… just let it
  11. then, when logged in, open the Mac AppStore-app and notice that the button under the macOS Sierra now says “download” ; click on it
  12. after the download has completed, you should now see the installer window popup on your screen… proceed from there…

that’s it… it’s simple, but very time-consuming…
