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