fixed : macOS Mail.app can’t setup Planet.nl eMail account as IMAP

Posted on 23-06-2021 by MacManus.nl

Question :

I have macOS 10.15 Catalina and Mail.app 13.4 and for some reason, I am now getting an error saying that Mail.app can’t get new mail from my Planet.nl eMail account, even though it used to run without any problem for the past years (I had been using the mailserver setting outlined in this post without running into any problems).

I have tried creating a new eMail account for my Planet.nl-account in Mail.app, but that wasn’t possible without deleting the previously used Planet.nl-account from Mail.app first. But even after deleting the previous Planet.nl-account, whenever I try to setup a new eMail account for my Planet.nl-account, it is automatically set up as a POP3-mailbox and I can’t find any way to change it to an IMAP-mailbox afterwards…

Even though it works as a POP3-mailbox, I don’t want a POP3-mailbox since I want to use it on multiple devices constantly : I want to use it on my Mac, my iPhone and my iPad without running into syncing problems.

How do I setup my Planet.nl-account as an IMAP-mailbox on Mail.app ?

Answer :

The problem you are running into seems to have to do with the fact that it’s a long long time ago (actually in the summer of 2008, so nearly 15 years ago) that internetprovider Planet.nl was integrated into (or ‘replaced by’ if you prefer) it’s mother-brand internetprovider KPN, which meant that all Planet.nl mail-servers were replaced by KPNmail.nl mail-servers.

Here’s how to fix this :

first open Safari (your internet browser) and goto your KPN Webmail : https://webmail.kpnmail.nl/mail/logon.asp
login using username@planet.nl (your Planet.nl eMail address) as your login
see if the password that you are using works here to login
if your password doesn’t work, see if you can find the password that does work to login to the KPN Webmail website
if you still can’t find the correct password, go here to reset it : https://www.kpn.com/service/internet/e-mail/wachtwoord-of-gebruikersnaam-vergeten.htm
then, open Mail.app on your Mac to delete the existing Planet.nl eMail-account
goto Mail (in the top menu bar) > Prefereces > Accounts (tab) > select the Planet.nl account (from the list on the left) > – (the button with a minus-sign ; a.k.a. ‘delete’)
then goto Apple-icon (top-left in upper menu bar) > System Preferences > Internet Accounts > Add Other Account (bottom option on the right)
now, in the window that opens, DO NOT type username@planet.nl as the new eMail address, but use username@kpnmail.nl instead !!! (even if you have never used username@kpnmail as your eMail address, it is available for you if you have a username@planet.nl eMail address)
now you will get an error message AND the option to manually choose either POP or IMAP
at ‘E-mailadres:’ put username@planet.nl (= the Planet.nl eMail address you want to use)
at ‘Gebruikersnaam:’ put accountname@planet.n (= the Planet.nl account that usually consists of your last name and 3 numbers ; do not forget to add @planet.nl after it)
at ‘Wachtwoord:” put your password (the one that works for KPN Webmail)
at ‘Type account:’ choose IMAP
at ‘Server inkomende e-mail:’ put imap.kpnmail.nl
at ‘Server uitgaande e-mail:’ put smtp.kpnmail.nl
then click the ‘Log in’-button
Then open Mail.app and see that your Planet.nl eMail-account has been added and that your mail is being fetched

That’s it !

fixed : “This block has encountered an error and cannot be previewed” error in WordPress Dashboard

Posted on 28-05-2021 by MacManus.nl

Question :

My WordPress.com website has been shifted to the revamped version of the WordPress Dashboard, but now, when I am trying to re-edit posts from before September 2020, I can only see the post’s title in the edit page… the body text is replaced by an error message saying “This block has encountered an error and cannot be previewed”.

What can I do to fix this ?

Answer :

The underlying problem is not exactly clear, but the solution is rather simple :

make sure you are running the latest version of macOS, if not : upgrade to the latest version of macOS
make sure you are running the latest version of Safari (or the browser you are using), if not : upgade to the latest version
open Safari
goto “View” (in the top menu bar)
click on “Reload without Content Blockers” (from the pulldown menu)
- Note : the regular “Reload Page (CMD+R)” will NOT solve the problem !

That’s it !

fixed : CanoScan 5600F driver for macOS Big_Sur

Posted on 17-03-2021 by MacManus.nl

Question :

I have a Canon CanoScan 5600F scanner that worked great with my previous Mac, but now I have upgraded to a new Mac running macOS 11.0 Big_Sur.

I’ve looked on the Canon website and searched the internet, but there is no macOS 11.0 Big_Sur compatible driver available for this scanner.

Is there any way to use this CanoScan 5600F scanner in macOS 11.0 Big_Sur ?

Answer :

Yes, there is :

goto Canon’s US website : https://www.usa.canon.com
choose Support > Scanners > Film & Negative Scanner > CanoScan 5600F
or use this link : https://www.usa.canon.com/internet/portal/us/home/support/details/scanners/film-negative-scanner/canoscan-5600f/canoscan-5600f?subtab=downloads-drivers
there, choose the “Drivers & Downloads” tab
then, choose “macOS Mojave v10.14” as your operating system and “English” as your language
then, choose the “Drivers” tab
now, you will see 2 drivers listed :
- > 5600F Scanner Driver Ver.14.11.5h (Mac) : msd_-mac_cs5600f-14_11_5h-ea8_2.dmg
  - > ICA Driver Ver.4.1.4a (Mac) : misd-mac-ijscanner2-4_1_4-ea21_3.dmg
download both of them
- note that despite the fact that both are versions from 2018, these will still work with macOS 11.0 Big_Sur
goto your downloads folder
first, double-click on the file named msd_-mac_cs5600f-14_11_5h-ea8_2.dmg
this will mount the ScanGear_CanoScan 5600F_141105.pkg
again, click on that and version 14.11 of the ScanGear driver installer will open
now, follow the on-screen directions and the latest ScanGear driver will be installed
then, double-click on the file named misd-mac-ijscanner2-4_1_4-ea21_3.dmg
this will mount the Canon IJScanner2_040104.pkg
again, click on that and version 4.1.4 the IJScanner2 driver installer will open
now, follow the on-screen directions and the latest IJScanner2 driver will be installed
when done, goto System Preferences > Printers & Scanners
if the CanoScan 5600F is already listed on the left, click it
if not, click the +sign (plus-sign) to add the scanner first
when done, click the CanoScan 5600F in the list on the left
when the scanner details open on the right, click on the “Open Scanner”-button
now, the built-in macOS scanner-app will open and it will immediately do a preview scan of whatever is in the scanner

NOTE : you might run into a small problem every once in a while ; when the automatic scanning preview starts, you might get an error saying “Scanner reported an error – Cannot communicate with scanner for these reasons: – Scanner is turned off. – USB cable is disconnected. Please check and try again.” If so, just flip the scanner’s ON/OFF-switch in OFF-position manually and then back into ON-posistie. That should help in making the scanner preview work again.

enjoy 😉

fixed : Canon scanner error -21345 on M1 Mac

Posted on 16-03-2021 by MacManus.nl

Question :

I have have just upgraded to a new MacBook Air M1 2020 (with an Apple M1 processor) running macOS 11.0 Big_Sur. Now, I am trying to get my Canon PIXMA MG3250 All-in-one printer-scanner to work with it… but even though I can get the printer function to work, when I want it to scan I get an error…

Installing the Canon MG3250 through System Preferecens > Printers & Scanners > Add Printer was really simple as it was immediately seen through Bonjour. After installing, the MG3250’s icon is listed on the left, and when I click it, the window opens where I can choose either the “Print” or the “Scan” tab. After choosing the later, I get the “Open scanner”-button, and when I click that, the built-in macOS scanner-app opens the “Scanner” window… which gives this error : “Failed to open a connection to the device (-121345)” each time I try. I just can’t get it to work.

What is wrong ?

Answer :

When you get this error in this setup, you will probably have gotten an error saying “IJScanner3” also. Do this to fix it :

goto the Canon UK website : https://www.canon.co.uk
there, browse to the PIXMA MG3250’s Driver Support-page or go there directly using this link : https://www.canon.co.uk/support/consumer_products/products/fax__multifunctionals/inkjet/pixma_mg_series/pixma_mg3250.html?type=drivers&language=en&os=macos%2010.15%20(catalina)
- Yes, that’s right, even though you are running macOS 11.0 Big_Sur and Canon tells you there is no driver for such an advanced OS, the macOS 10.15 Catalina driver still works
when you see the ICA Driver Ver. 4.0.0a (Mac) version listed, click the blue download button to download
in your downloads folder, you will now find a file called miss-mac-ijscanner3-4_0_0-ea19_2.dmg
click that file and it will mount an installer called Canon IJScanner3_040000.pkg
click that file and the 2020-version of the scanner driver will be installed
when done, make sure the System Preferences are closed
then open System Preferences > Printers & Scanners > MG3250 again and click the “Open Scanner”-button
now, the built-in scanner-app will open the Scanner-window again, but hits time without the error… so you are good to go !

That’s it !

fixed : macOS Big_Sur installer hangs at 95%

Posted on 13-11-2020 by MacManus.nl

Question :
I just downloaded the new macOS 11 Big_Sur on my Mac mini (2018) and started installing. But even though it said that installing would take about 28 minutes, it’s now about 40 minutes and the installer hangs, the screen is black with just the white Apple-logo and an installer bar that hangs at about 95%.

What can I do ?

Answer :

Just wait for about 15 to 20 minutes more, and it might just finish the last 5% of the installing process. If it doesn’t, press the power button on your Mac mini until it shuts down completely. Then, restart your Mac mini by pressing the power button again.

Note : this will probably work for any Mac, but it has been tested only on Mac mini (2018).

That’s it !

enjoy 😉
