fixed : MacBook Pro sighs then hangs during startup without progress bar over and over again

Posted on by

Question :

I have a  2018 MacBook Pro 13″ with TouchBar and 4 Thunderbolt3 ports that seems to hang during startup : the MacBook ‘sighs’ (fan noise) during startup and shows only a black screen with a white Apple-logo, but no progress bar as usual… then it automatically restarts… and the same thing repeats itself…

Is there any way to solve this ?

 

Answer :

This might be caused by a hardware problem, so if it happens frequently, you should take your MacBook Pro to an AppleStore or authorized Apple Repair shop for repair.

But before you do so, try this, as it might fix your problem :

If you do see a progress bar during startup, look at this post :

fixed : MacBook Pro hangs during final stage of macOS startup

If you do not see a progress bar during startup, do this :

  • unplug everything else from the USB-C ports
  • now plug in the USB-C power-adapter
  • then, if you can, plug-in a USB-C-to-Ethernet-adapter and make an ethernet-connection to your network (and the Internet), if not leave it
  • then, press the ON/OFF-fingerscan-button (top-right in the Touch Bar) to restart your Mac
  • then, during restart, immediately press the [CMD]+[ALT]+[R] key-combo on your keyboard
  • keep this key-combo pressed for about 30 seconds, then release
  • now, leave your MacBook connected to power and internet overnight
  • in the morning, your MacBook will have reinstalled the latest version of macOS

…and you will be good to go 😉

If the problem persists overnight, you might want to try this also, before you decide to bring in your MacBook Pro for repair :

  • create a macOS installer on a USB-stick (or even a USB-C stick)
    • as your own MacBook Pro is not available for this, you need to do this on another Mac or ask someone to do this for you
    • instructions on doing this can be found here on Apple.com
  • then plug the USB-C stick (or USB-stick with a USB-to-USB-C-adapter) into your MacBook Pro
  • then restart your MacBook Pro, while pressing the [ALT]-key on your keyboard
  • release the [ALT]-key when the Startup Manager window opens
  • then select the USB-stick as your startup disk
  • then follow the onscreen instructions for (re)installing macOS

That’s it !

As mentioned before : if you keep running into this problem frequently, you might have a hardware problem and you should bring your MacBook Pro in for repair.

enjoy 😉

fixed : old hard reset procedure doesn’t work on new iPhones with finger scan

Posted on by

Question :

I just encountered an error (or bug) in iOS forcing me to do a hard reset on my iPhone, but when I try the good-old reset-procedure by pressing both the MENU- and POWER-button simultaneously, there’s no reset… just a click-sound and a screenshot photo being taken…

What’s going on ?

 

Answer :

For all iPhones (and iPads) that still have the MENU-button (*) without fingerscan [ so all iPhones up until and including the iPhone 5 and 5c ], the procedure for a hard reset is :

  • make sure you have the PIN-code of your SIM-card at hand
  • press and hold the MENU- and POWER-buttons (*) of your iPhone/iPad simultaneously until the entire screen turns black and the Apple logo reappears
  • then release both buttons and wait for the screen to go back to normal
  • and when asked, enter the PIN-code to unlock your SIM-card

…that’s it

For all iPhones that have the new fingerscanning MENU-button (*) [ so all iPhones starting from the iPhone 5s and iPhone 6 and newer ], the above procedure does no longer work, so there is a new procedure for a hard reset :

  • make sure you have the PIN-code of your SIM-card at hand
  • press and hold the POWER-button (*) until the screen goes fuzzy and the ‘slide to power off’-slider appears
  • then release the POWER-button and slide the slider to the right to turn the iPhone off
  • wait for the screen to go black
  • then press and hold the POWER-button until the Apple logo (re)appears
  • then release the POWER-button and wait for the screen to go back to normal
  • and when asked, enter the PIN-code to unlock your SIM-card

UPDATE : since iOS 9.3 the ‘old’ procedure for a hard reset was re-introduced as an extra for the newer fingerscanning iPhones, so these can now also be reset by simultaneously pressing & holding the MENU- and POWER-buttons 

…that’s it

(*) the MENU-button is the button that is on the front side of your iPhone or iPad just below the screen :

  • on iPhones up until the iPhone 5 and 5c, the MENU-button has a ’rounded square’ icon on it
  • on iPhone 5s, iPhone 6 and newer, the MENU-button has no printing on it, but it has an (invisible) fingerscanning-sensor inside

…the POWER-button is the button that is used to turn the iPhone/iPad screen ON and OFF :

  • on iPhones up until the iPhone 5c and 5s, the POWER-button is on the top-side of the iPhone (just like it is on iPads)
  • on iPhone 6 and newer, the POWER-button is on the right-side of the iPhone

fixed : no audio on iPhone, just an annoying beeping noise

Question :

Today the output-sound of my new iPhone 6s turned into complete noise. No matter which app I use, be it YouTube, iTunes Music or online TV, all sound is reduced to an alternating beep-sound. I can turn the volume down (or up), but it doesn’t go away, no matter what I try…

What can I do ?

 

Answer :

Regardless of the exact cause of the error you run into… your best option when encountering weird behavior of your iOS-device (iPhone/iPad) is to do a reset.

For your audio-problem this is tested and proven to work also.

For the iPhone 6s the reset-procedure is a little different from the one used on previous iPhones (*) :

  • make sure you have the PIN-code of your SIM-card at hand
  • press and hold the POWER-button until the screen goes fuzzy and the ‘slide to power off’-slider appears
  • then release the POWER-button and slide the slider to the right to turn the iPhone off
  • wait for the screen to go black
  • then press and hold the POWER-button until the Apple logo (re)appears
  • then release the POWER-button and wait for the screen to go back to normal
  • and when asked, enter the PIN-code to unlock your SIM-card

…that’s it

😉

 

On previous iPhones the reset-procedure is :

  • make sure you have the PIN-code of your SIM-card at hand
  • press and hold the MENU- and POWER-buttons of your iPhone/iPad simultaneously until the entire screen turns black and the Apple logo reappears
  • then release both buttons and wait for the screen to go back to normal
  • and when asked, enter the PIN-code to unlock your SIM-card

…that’s it

fixed : wake MacBook from deep sleep

Question :

Whenever I think I am only closing the lid on my MacBook for a few minutes, but get distracted and end up not turning back to it for about an hour, my MacBook seems to have fallen into deep sleep. Then nothing seems to help to get it ‘back to life’, and even though the battery is still indicating about ‘half full’, the usual click on the SPACE-bar doesn’t help, and neither does typing any key or key-combo on the keyboard…

My MacBook’s sleep is actually so deep my wife calls it ‘hibernation’, and my children call it ‘zombie Mac’…

So I always end up either taking out the battery to completely restart my MacBook or keeping the power-button pressed until it finally restarts…

Isn’t there any other way to wake my MacBook from deep sleep ?

Answer :

Yes, there is.

The solution you have been so near to the simplest solution, but you didn’t recognize it…

Instead of keeping the power-button pressed, you should just press the power-button for one quick second…

…that’s is. Then your MacBook will slowly wake from deep sleep… it will first show a faded white-ish screen with a progress bar… and if that’s finished loading, your MacBook (Pro) will be right back were you left off…
