My Mac will not recognize my Canon MX 920 for scanning

I am sorry you are having scanner problems. If you will bear with me, I will offer some things to consider which may be useful. Whenever we install an operating system upgrade or some OS updates, printers and scanners will often stop working. Then a new OS compliant software must be installed. Experience has shown that many printer/scanner manufacturers are very slow to provide updated software. What you can do is to thoroughly check the vendor's web site for updated compliant software that works. If none is available, then you should ask when it will be released. If that doesn't work, you can try scanning using Apple's Image Capture app. It will scan, but is not full featured. Another alternative is to download and try the full featured scanner software from VueScan. You can try it for free. It will show a watermark until you purchase it. I bought it and can recommend it. I have no association with VueScan. Good luck.

Hi,

Would anything in the article 'You do not have permission to open the application' when using a scanner on Mac - Apple Support apply in this case? Canon has some details in https://support.usa.canon.com/kb/index?page=content&id=ART180175 .

Although not a free solution, if you get VueScan it will be a one time purchase and be good for any system to come along for the Mac. And your model is supported: Canon Scanner Drivers
