fixed : get rid of Virus Infection warnings in Calendar.app

Question :
For some reason, my Calendar.app is flooding with red warning messages like “Your iPhone is infected”, “Virus detected”, “Critical Warning”, “Your iPhone is in danger” etc.

Is this true ?
Where did this come from ?
How can I get rid of these ?

Answer :

It is not a virus infection. These are not real iOS Error Messages. These are Calendar Events. You have recently clicked on some unreliable internet link that has subscribed you to an external event calendar…

To get rid of these, do this :

  • on your iPhone, open the Calendar.app
  • in the window that opens you will see your current appointments, and in the bottom-bar three buttons : “Today”, “Calendars” and “Inbox”
  • click on the “Calendars” button (bottom center)
  • in the pull-up screen that appears, you will see all Calendar-feeds that you have active
  • scroll down to the “Subscribed” chapter
  • if you have just one entry there, click on the coloured circle in front of it to remove the white checkmark
  • if you have more than one entry in the “Subscribed” chapter, click on the coloured circle in front of the top/first one to remove the white checkmark
  • then, click “Done” (top-right) to see if the error messages are gone
  • if they are, proceed – if not, redo the above step until the error messages have gone from your calendar
  • when you see that the error messages have disappeared from the regular Calendar view, click on the “Calendars” button (bottom center) again
  • then, in the pull-up screen that appears, scroll down to the “Subscribed” chapter again and click on the Info-button (encircled i-letter) that is at the right side of the name of the Calendar that you have previously unchecked (to make the error messages disappear)
  • in the “Edit Calendar” page that opens, scroll down completely and click on “Delete Calendar” (in red – completely at the bottom)
  • now, the pesky calendar subscription will be gone

That’s it !

fixed : convert video for WhatsApp

Question :

I have a short video file (a movie clip) that I want to share with my friends on WhatsApp. When I drag&drop it into the WhatsApp.app in macOS, the file appears to start uploading… but when done, there is no preview shown and no Play-button, just a file icon… as if it were an unknown or incompatible type of file…

What can I do to fix this ?

Answer :

Before uploading your video file to WhatsApp, you must make sure your video file meets WhatsApp’s file requirements :

  • video format preferably MP4 in H.264 or MPEG-4 codec ( MKV, AVI or 3GP will also do )
  • audio format preferably AAC ( or AC3 codec )
  • file size smaller than about 16MB ( in reality even 18MB might be okay )
    • usually, this means your movie clip will be about 90 seconds, but by tweaking the display size and the frame rate ( fps ) you can even squeeze 3 minutes or more into about 16MB

Do this to check your video’s specifications :

  • right-click ( CTRL-click ) on the movie clip’s icon
  • select “Get Info” from the popup-menu
  • in the window that opens, check these :
    • the file name either has the “.mov” or “.mp4” file extension
    • at “Size:” less that 18MB should be listed
    • at “Codecs:” either “H.264” or “H.264, AAC” is listed

If these are all okay, you should be able to just drag&drop the movie clip into the macOS WhatsApp.app.

If not, you will have to convert the movie clip. To do this conversion, do this :

  • first, download the FREE OmniConverter.app ( by 7littlemen ) from the Mac AppStore :
  • then, open the OmniConverter.app and click on “Convert Video” from the list on the left
  • then, drag&drop your movie clip file onto the OmniConverter window
  • now, at the right of the arrow (in the middle), check if “MP4” is listed and the file size is less than 18MB
    • if you do not see “MP4” listed at the right of the middle arrow, click the Format-button
      • in the window that opens, select the “Device”-tab
      • then, select “iPhone” from the list on the left
      • then, select the “iPhone HD” option
      • now, click the Confirm-button
    • if you see a file size larger than 18MB listed at the right of the middle arrow, click the Edit-button
      • in the window that opens, at “Video”>”Encoder:” select “H.264”
      • and at “Audio”>”Encoder:” select “AAC”
      • leave the rest as is and click the Confirm-button
  • back in the Convert Video window, click on the Start-button ( circled arrow icon, at the right )
  • now, wait for the conversion to complete
    • if the file size already was less than 18MB, you’re usually okay and you will not need to do extra compression
    • if the file size was over 18MB, do this :
      • open the OmniConverter.app and click on “Compress Video” from the list on the left
      • drag&drop the .mp4-video you’ve just converted onto the OmniConverter window
      • check if the file size listed at the right of the arrow (in the middle) is less than 16MB
        • if so, click the Start-button on the right
        • if not, click the Edit-button (below the arrow)
        • in the window that opens, set the “Quality:”-slider in-between “Mid” and “High”, set “Resolution:” to “720P” and set “Frame Rate:” to “24 FPS”
        • if at “Size:” it now says anything less than 16MB, click the Confirm-button
        • if at “Size:” it says anything over 30MB, set “Resolution:” to “480P”
        • if at “Size:” it says anything between 20MB and 30MB, set the “Quality:”-slider to “Mid”
        • now, if at “Size:” it still says anything over 18MB, start tweaking the available settings until at “Size:” it says about 15MB ( see how much the file size decreases when you tweak each setting to find the optimal combination of settings )
        • when done, click the Confirm-button
      • now, in the “Compress Video” window, click the Start-button
      • …and wait for the compression to finish

After the file conversion, drag&drop the converted movie clip into the WhatsApp.app to share it with your friends…

That’s it !

fixed : firmware-update for 70mai A800 dashcam WiFi

Question :

I just bought the best dashcam I could find for an affordable price : the Xiaomi 70mai A800 4K Ultra HD video with WiFi, GPS and ADAS driver assistance built-in.

I want to make sure I have the latest available firmware on the dashcam to enable all available features…

How do I install the latest A800-firmware ?

 

Answer :

Aside from all the great features already included in the Xiaomi 70mai A800 dashcam, user-friendly do-it-yourself firmware upgrades are also available to enable even more new features.

First, make sure you are using the right iOS-app : you need the 70mai (Worldwide) app that can be downloaded here.

Now, connect your iPhone to the 70mai WiFi-network and open the 70mai.app. If you have problems connecting to the 70mai WiFi-network, see this post.

Then, open the 70mai.app and do this to upgrade the firmware :

  • make sure you are on the 70mai.app’s main page (the window labeled “70mai” with a picture of a blue car and your 70mai Dash Cam A800 listed below it)
    • if the 70mai.app opens in the “70mai Dash Cam”-window with the current video stream of the dashcam and the “Take Photo” and “Album”-buttons below it, click the “<“-button top-left and in the “Exit the dash cam homepage?”-popup, click “OK”
  • in the “70mai”-window, make sure that at “Device” it says “Connected”
    • if “Not conneted” is listed, click on it
    • the “70mai Dash Cam”-window will open and the connection will be re-established
    • then, return to the “70mai”-window by clicking on the “<“-button top-left and in the “Exit the dash cam homepage?”-popup, click “OK”
  • back in the “70mai”-window, click the person-icon top-left
  • in the slide-in window click on “My Devices”
  • in the “My Devices”-window, click on “70mai Dash Cam A800”
  • in the next window (also called “My Devices”), click “Firmware Update”
  • when the “Firmware update”-window opens, follow the on-screen instructions to upgrade the firmware to the latest version

…that’s it !

enjoy 😉

Note that you can adjust various dashcam settings (like the Speaker Volume, Video Resolution, Parking Surveillance, ADAS Driver Assistance, etc.) by clicking on the 3dot-icon top-right in the “70mai Dash Cam A800”-screen (where you can see the current video stream from the dashcam with the “Take Photo” and “Album”-buttons below it).

 

 

 

fixed : 70mai A800 dashcam WiFi connection error

Question :

I just bought the best dashcam I could find for an affordable price : the Xiaomi 70mai A800 4K Ultra HD video with WiFi, GPS and ADAS driver assistance built-in.

I can’t get it to connect properly to my iPhone over WiFi however… I can find the 70mai WiFi network in the list of available WiFi networks in the iOS Settings-app, and I can connect to it, since it is shown as the connected WiFi-network… but the WiFi icon (the pie-shaped triangle) isn’t shown in the upper right corner of my iPhone… and when I startup the 70mai.app and click on the “70mai Dash Cam A800” in the “Please add 70mai devices”-window, I get an error : “Unable to get Wi-Fi connection Please enter [Settings – 70mai] to open location permission and then connect the device.” …and when I click on the “Go to open it”-button, the Settings-app opens …there I can set Wi-Fi, but that is already connected to the 70mai WiFi-network…

What is going on… how can I fix this ?

 

Answer :

The solution is simple, but you didn’t understand the given directions… probably because the the error message isn’t really straight forward : it’s in awkwardly translated English and the button only links halfway to where you need to adjust the settings…

First, make sure you are using the right iOS-app : you need the 70mai (Worldwide) app that can be downloaded here.

Then, do this :

  • connect the 70mai A800 dashcam to power
  • open the “System Settings” page (the icon is a hexagram with a dot in it)
    • Note that there’s no touch-screen so you should use the 4 buttons below the screen to navigate through the on-screen menu-structure
  • On the Settings page, you need to set “Wi-Fi hotspot” to “Enable” :
    • select “Disable” (at the top line, right of “Wi-Fi hotspot”)
    • in the “Wi-Fi hotspot”-page that opens you will see the name of the WiFi-network (at “Wi-Fi SSID”) and the WiFi-password (at “Password”)
    • remember these (or leave this screen open)

Then, open the 70mai.app on your iPhone and do this :

  • on the first page (simply called “70mai”) click the “Add device”-button (the only button on-screen)
  • in the “Please add 70mai devices”-page that opens, scroll down to “70mai Dash Cam A800” and click on it
  • when you get the “Unable to get Wi-Fi connection Please enter [Settings – 70mai] to open location permission and then connect the device.” error message, click on “Go to open it”
  • now the Settings.app will open, but it won’t always on the same page inside the Settings.app
  • so, make sure you go to the main Settings-page and clcik on “Wi-Fi” in the list
  • when the “Wi-Fi”-page opens, select the 70mai WiFi-network (with the name that was listed at Wi-Fi SSID”) from the list of “Other Networks” (or “My Networks”)
  • if the WiFi-password is required, use the “Password” that is (or was) displayed on the dashcam’s screen
  • now, even when the 70mai WiFi-network is connected you will still see 4G (or 3G or some other mobile data indication) instead of the WiFi-icon in the top-right corner of your iPhone screen
  • then click on “<Setttings” top-left
  • back in the main Settings-page, scroll all the way down to “70mai” (in the list of apps that starts after “Game Center”) and click on it
  • in the “70mai” page that opens, set “Location” to “While Using the App”
    • you could also set it to “Always”, but that isn’t a great idea since the 70mai WiFi-network is rather poorly protected
  • now, open the 70mai.app again
  • in the “Please add 70mai devices”-page, click on “70mai Dash Cam A800”
  • now, the “Turn on Wi-Fi hotspot”-page will open with a picture that resembles the “Wi-Fi hotspot” page that is displayed on the dashcam
  • there, you should click on “Dash cam WiFi hotspot is turned on” (eventhough it appears to be greyed-out) so a green checkmark will appear
  • then click “Next”
  • on the next page (the “Connect to WiFi hotspot”-page) click “Connect”
  • now the Settings.app will open again, check that the 70mai WiFi-network is listed at “Wi-Fi”
  • then, open the 70mai.app and you will see a countdown-circle on your iPhone and you will hear a voice from the dashcam
  • so, go to the dashcam screen and tap the button bottom-right to confirm
  • now you will see what the dashcam is ‘seeing’ / ‘recording’ in the 70mai.app on your iPhone

…that’s it !

enjoy 😉

Note that you can adjust various dashcam settings (like the Speaker Volume, Video Resolution, Parking Surveillance, ADAS Driver Assistance, etc.) by clicking on the 3dot-icon top-right in the 70mai-app screen.

 

 

 

fixed : quick slideshow of a folder of pictures

Question :
Someone sent me a bunch of photos that I need to review. I have them in a folder, but I don’t want to import them into Photos.app, Keynote or PowerPoint or even Preview.app to have a look at them and select the most important ones.

Is there any option or simple app to do this ?

 

Answer :

Yes there is, there is an option for this in macOS (and OSX) called Quick Look. In previous versions of OSX and Mac OSX the Quick Look option was visible in any Finder window as a ‘button with an eye icon on it’, in macOS it is slightly hidden in the pulldown menu that opens when you click the ‘button with a sprocket (gear) icon on it’.

There’s even a shortcut for this :

  • open a Finder window
  • open the folder with the photos in it
  • select the photos you want to review (hold the CMD-key while picking photos one-by-one, hold the SHIFT-key to select multiple photos in a row, or press the CMD + A key combo to select all photos)
  • then press the SPACEBAR to view all selected photos as a slideshow
  • or press the ALT + SPACE key combo to view all selected photos as a full screen slideshow
  • note : the file names are shown with each photo, so if you need to review and select photos you will know which photos you have chosen

That’s it.

enjoy 😉

 

 

fixed : use old iPad as an extra screen for your Mac (or PC)

Question :

Since we are working from home a lot (and the children are home schooling), and we have several old iPads and iPhones lying around gathering dust, we were wondering if it would be possible to use them as second screens on our Macs and Windows PCs to make our work and homework easier by being able to do this (and more) :

  • manage our music playlist (iTunes, Apple Music, Spotify) on our old iPad/iPhone whilst running  MS Office on our Mac/PC without switching apps
  • use our old iPad/iPhone’s touchscreen to put a signature under a PDF-document whilst typing it on our Mac/PC
  • use our old iPad/iPhone as a drawing tablet for our Mac/PC
  • videochat or view an online presentation onour Mac/PC whilst making notes on our old iPad/iPhone using a full-size keyboard (and easily swapping the two around when needed)

We noticed Apple has introduced this great feature called Sidecar that enables you to use your iPad (or iPhone) as a second screen for your Mac. But when I looked at the Sidecar requirements on the Apple website, I found that our older iPads/iPhones aren’t supported.

Is there any way to use Sidecar (or something similar) on our old iPads/iPhones ?

 

Answer :

Yes, even though you cannot use Sidecar on any unsupported iPad, iPhone or Mac, there is an alternative that works just as great for any old iPad (or iPhone) and is not limited to a Mac, but does support Windows PCs also… and best of all : it’s FREE.

This is ideal for working from home and home schooling since you can do all this (and more) :

  • manage your music playlist (iTunes, Apple Music, Spotify) on your iPad whilst running  MS Office on your Mac/PC without switching apps
  • use your iPad/iPhone’s touchscreen to put a signature under a PDF-document whilst typing it on your Mac/PC
  • use your iPad/iPhone as a drawing tablet for your Mac/PC
  • videochat or view an online presentation on my Mac/PC whilst making notes on my iPad/iPhone using a full-size keyboard (and easily swapping the two around when needed)

  • iPad 2 or newer
  • any iPad mini
  • any iPad Air
  • any iPad Pro
  • any aluminum iMac (iMac “Mid 2007” or newer)
  • any iMac Pro
  • Mac mini “Early 2009” or newer
  • Mac Pro “Early 2008” or newer
  • white MacBook “Early 2009” or newer
  • any aluminum MacBook

  • then, plug your iPad/iPhone’s USB-cable into your Mac/PC
  • then run the Splashtop Wired XDisplay app on your Mac/PC
  • then run the Splashtop Wired XDisplay app on your iPad/iPhone
  • then goto the Settings on your Mac/PC, find the Screen Settings and arrange your screens the way you like
    • you can choose “Mirror Screen” to see exactly the same on your MAc/PC and your iPad/iPhone
    • you can choose “Extend Screen” to arrange the iPad/iPhone as an add-on for your desktop
    • if you already have a second screen attached to your Mac/PC, you can use your iPad/iPhone as an additional third screen also

That’s it !
