fixed : external display goes black when I close my MacBook

Question :

Since I need to work form home at this moment, I have connected an external display. It works great and I now have a far better overview than I had on my tiny MacBook Pro screen. Now I have connected a USB-keyboard and a wireless mouse, so I would like to close my MacBook’s lid while I’m working on the external display. But, somehow, every time I close my MacBook’s lid, the connection to the display is lost and the display goes black…

What is going on ?

 

Answer :

To prevent your battery from draining while you are not using your MacBook, all connections are cut off when the lid is closed (since you cannot access the keyboard or the screen when the lid is closed). This also means that the connection to your external display will be cut off whenever you close your MacBook’s lid.

However : since your MacBook’s battery will no drain as long as extra power is provided, this shut down feature will not be activated as long as your MacBook is plugged into the wall charger. So, there’s your answer : just plug your MacBook into external power, and your external display will not go black when you close the MacBook’s lid.

Note : if you already have your MacBook connected to external power and your external display still goes black, see this post.

That’s it !

fixed : NVIDIA GeForce NOW completely broken in macOS 10.15 Catalina

Question :

I’ve just upgraded to macOS 10.15 Catalina on my MacBook Pro, but now the NVIDIA GeForce NOW app is broken so I can no longer play Fortnite in a decent way…

The NVIDIA GeForce NOW app seemed to have disappeared completely from my Mac, but I found it is still in the Applications folder, but the icon is now a greyed-out NO ENTRY sign… so nothing happens when I click on it…

What can I do ?

 

Answer :

For some unknown reason, some upgrades to macOS 10.15 Catalina break the NVIDIA GeForce Now app…

Luckily, the solution is simple : download the latest version of NVIDIA GeForce NOWΒ here and install it… choose Replace Old Version during install and then just restart the app…

It’s simple as that…

fixed : Birthdays not showing in macOS Calendar.app

Question :

I just did a clean install of macOS on my Mac and everything works fine. Except for one thing…

The birthdays of my contacts are not showing up in Calendar.app even though they were properly showing in Calendar.app on my previous version of macOS and they are still showing up properly in Calendar.app on my iPhone.

I’ve already tried unchecking and re-checking the checkmark at “Birthdays” in the list of available calendars (at “Other”),Β login out of iCloud and back in, restarting my Mac, adjusting some birthdays in Contacts.app, etc. Simply put : I’ve tried any solution I could think of…

How can I fix this ?

Answer :

The solution might be simple, but easily overlooked :

in Calendar.app on macOS, go to “View” in the menu-bar and when the pulldown-menu appears, put a checkmark at “Show All-Day Events”, then click “Refresh Calendars”.

Now check if that solves your problem. If it doesn’t, try this :

  • goto Calendar.app
  • select Calendar (in the top menu-bar)
  • select Preferences (from the pull-down menu)
  • select General (the left tab)
  • put a checkmark at β€œShow Birthdays calendar”
  • note : if you already had a checkmark at β€œShow Birthdays calendar”, do this also :
    • remove the checkmark
    • close the Calendar-app
    • restart your Mac
    • open the Calendar-app
    • put the checkmark back at β€œShow Birthdays calendar”

That’s it.

fixed : internet on wireless but not on LAN according to AirPort Utility

Question :

Lately I have had aΒ badΒ and unstable internet connection. I have a Mac and it has been working fine for years. My internet provider is Vodafone-Ziggo.

I tried to find out what was wrong using the AirPortUtility.app on my Mac, and I found something strange : when selecting my wireless WiFi-network, my internet connection is presumed working, but when selecting my wired LAN-network, I get an error message saying there is no internet connection.

If it would have been the other way around, I could think of an explanation… but having wireless internet connection from my router and not LAN-internet just doesn’t make sense…

I’ve tried numerous resets of the Ziggo-modem, of my TimeCapsule and of my Mac. Nothing helps.

Do you have any suggestions on fixing this ?

 

Answer :

Even thoughΒ you’ve tried most of the available options already, there is one other thing I would suggest to try :

  • make sure the UTP/Ethernet/LAN-cable is correctly connected into both your Mac and the ‘local network device’ (be it a TimeCapsule, a router, a modem, a network-switch or a wall-socket)
  • then, on your Mac : click on the Apple-icon (top-left on your Mac’s desktop screen)
  • in the pulldown menu, click on “System Preferences”
  • in the window that opens (“System Preferences”), click on “Network”
  • in the window that opens (“Network”), click on “Ethernet” in the list on the left
  • in the info that appears on the right, check if it says “Status : Connected”
  • if it doesn’t, your UTP/Ethernet/LAN-cable isn’t connected properly, so check all network-cables again until it saysΒ “Status : Connected”
  • then, click the Advanced-button
  • in the window that opens, click on the DNS-tab
  • in the info that opens, at “DNS Servers:” make sure that you have at least included one of the following DNS Servers : 8.8.8.8 (Google), 8.8.4.4 (Google), 208.67.222.222 (OpenDNS) and/or 208.67.220.220 (OpenDNS)
  • if none of those DNS Servers are listed yet, add them by clicking on the +/Plus-button bottom-left
  • then click on the Proxies-tab (of the elongated TCP/IP-button)
  • in the info that opens, make sure to remove the check-mark at both “Web Proxy (HTTP)” and “Secure Web Proxy (HTTPS)”
  • in case both were already switched OFF, I would suggest to switch both of them to ON
  • then leave the rest as is, and click on the OK-button
  • in the previous window that appears, click the “Apply”
  • now check the AirPortUtility.app again, and you should see that the internet connection is back up for both the wireless and wired/LAN connection
  • also check by opening Safari (or another internet browser) and refresh the page by clicking on the circular arrow in the address bar

That’s it !

fixed : Benq monitor stays black when MacBook is switched on

Question :

I have a Benq BL2420PT external monitor as a desktop screen connected to my MacBook using a Displayport-cable (actually a miniDisplayport-to-Displayport-cable). When my MacBook goes into sleep mode or the Ben monitor goes into sleep mode itself the screen goes black. But when I try to revive the monitor by moving my external mouse or pressing any key on my (external) keyboard, the MacBook starts up, but the Ben monitor’s screen stays black.

This same thing sometimes happens when I startup my MacBook and close the lid before the Benq monitor switches on.

What can I do to fix this ?

 

Answer :

The following trick might help for other Benq monitors, and maybe even for different brands of monitors also. This works for the Benq BL2420PT monitor if the screen stays black even when the connected Mac is turned on :

  • on the frame of the screen, bottom right, you see 5 indicator lights, next to the Power-indicator ; these are all touch-buttons
  • if the Power-indicator/button is steadily glowing in white, don’t touch it ; only if it has another color, touch it to switch on the monitor
  • if the Power-indicator still doesn’t glow white, check if all cables are connected properly and make sure the physical ON/OFF-switch on the bottom of the screen is switched ON
  • touch the one indicator light/button that is nearest to the centre of the screen (so the most left one)
  • if a message appears “No cable connected”, just wait
  • if a menu appears with 5 cable connectors to choose from, don’t touch anything, just wait
  • just wait (usually up to 30 seconds, sometimes even a minute) and the screen will switch on

NOTE : the most important thing is that you DO NOTΒ (neither accidentally nor intentionally) touch any other indicator/button ! as this usually screws up the monitor’s software setting that corresponds to the physical cable connection (to correct that, you should toggle around with the these touch-buttons until the menu with the 5 cable connectors reappears and you can then choose the one that corresponds to your physically connected cable)

If the above doesn’t work, look here for alternate procedures to revive your black screen :

fixed : which version of Java do I have ?

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 7Β or higher.

How can I check (and update) ?

 

Answer :

Java is a free software platform which isΒ 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,Β 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 resultΒ of the check will beΒ 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.
