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 : which version of Java do I have ?

Posted on by

Question :

I would like to know which version of Java I have installed on my Mac, since the software I want to use will only run on Java 7 or higher.

How can I check (and update) ?

 

Answer :

Java is a free software platform which is operation system independent (so Mac & PC) created and maintained by Oracle. Despite it always having been a very reliable way of making cross platform games & applications, Apple has restricted the use of Java to ‘only when needed’ by default in the latest versions of OSX and macOS, because of the security risks involved in using Java and similar software that can run autonomously on your Mac next to macOS.

To find out which version of Java you have installed, do the online check that’s on this official website :

https://java.com/en/download/installed.jsp

Just follow the instructions given and the result of the check will be shown : you will either have the latest version installed, or you won’t… in that case update instructions will guide you to getting the latest version available for your Mac.

enjoy 😉

fixed : printer auto-install in Windows Vista won’t work

Question :

My HP DeskJet 930c prints colors if I print out the test page from the printer, but if I print from my Windows Vista PC, it only prints in grey-tones…

From the info on the HP website it has become clear to me that I have to reinstall the printer (and specifically the printer drivers) on Windows Vista.

But… according to HP the only way to reinstall the printer in Windows Vista using USB is to delete it from the Configuration Panel and then restart the PC and just plug in the printer and wait for Windows Vista to do the ‘magical’ auto-install…

The official HP instruction video can be found here :

http://bcove.me/4xavsoow

…and nothing happens when I do that.

And HP does not offer any other option… what can I do ?

 

Answer :

This is purely a Windows problem, and this weblog is for Apple solutions only. I do have a solution that will probably work for you, and I’ve not found that solution posted online anywhere, so I will provide it to you here ‘as is’ (meaning NO guarantee, NO additional help and NO service) ! Try at your own risk ! If it doesn’t work for you : I’m sorry… please ask a Windows-specialist.

————————-

The solution is simple (and it’s unexplainable why HP doesn’t mention this anywhere) :

Just reinstall the printer the way you would have done it in Windows XP :

– delete any previous installs of the printer from the Configuration Panel

– install all (essential) available Windows Vista updates using Vista’s built-in Security Panel

– restart your PC

– connect the printer to your PC using a USB printer cable

– go to START-menu

– then to Configuration Panel

– then to Printers

– then choose Add Printer

– choose Virtual USB Port 1 (or 2) as the connection to be used

– choose your Printer

– choose the dedicated driver [*]

– and wait for the installing to finish

– test your printer using any (color) document you have available, if you don’t have any useable color document available, use this printer test-page :

– that should be it : enjoy !

[*] if no driver is available, download it from the following website, then install and start over with this procedure from the beginning :

fixed : installing a new hard disk (option 1)

Posted on by

Here’s a simple 3-step way of replacing a HD in a Mac :

[ in this example a new HD is put into a Mac mini (version mid 2007) ]

1- clone the internal HD directly onto the new HD
These instructions assume you have another Intel-Mac and a USB-enclosure for a SATA-harddisk (that you will afterwards use to turn the old internal HD into an external one) available :
– put the new harddrive into the USB-enclosure
– connect the USB-cable to your other Intel-Mac
– connect the Mac mini to the Intel-Mac using a FireWire-cable
– (temporarily, just during startup) connect a USB-keyboard to your Mac mini
– startup the Mac mini while pressing the T-key on the keyboard (“Target Mode”)
– both the Mac mini and the USB-connected new HD will now show up in your Finder (on the Intel-Mac)
– open Disk Utility
– click on the Erase-tab
– select the USB-connected HD list on the left, and erase it in MacOS Extended (Journaled) format
[ BEWARE : do NOT format your HD in MacOS Extended (“Case-sensitive” Journaled) mode ! As that will prevent some applications to run ! e.g. Adobe Photoshop 10 Editor ]
– click on the Restore-tab
– from the list on the left drag the partition of your Mac mini onto the “Source”-field
– then drag the new partition from your new HD onto the “Destination”-field
– click the Restore-button, and wait

2- replace the HD
– open the instructions on how to replace the HD from the iFixit-website (or print them out) and read them

http://www.ifixit.com/Guide/Installing-Mac-mini-Model-A1176-Hard-Drive/1108/1

– get the new HD out of the USB-enclosure
– now gently open the Mac mini enclosure
– blow the dust of the interior using a compressed air blower [ do NOT use a hair dryer ! ] or using a vacuum cleaner with a piece of thin cloth (e.g. a napkin) tightly fit to the suction tube (to prevent anything from actually being sucked in)
– replace the HD (make sure the connectors are clean and fit thight)
– while you’re at it, you might also check the AirPort-card connector
– and finish up (all using the iFixit-instructions)

3- test the new HD
– restart
