Are you SURE it won't work?

YOU DO NOT HAVE THE PERMISSIONS! Ugh. Upgrading to Big Sur 11.5.1 murdered my old flatbed scanner, which I use all the time. Evidently, it's a problem for many many   many people. The following sequence worked, but I can't guarantee that it will work for you as well, since I deleted, added, re-deleted, upgraded and downgraded all kinds of files until it finally showed up without an error: Delete the scanner from Preferences Delete Canon utilities Remove any Canon-related files from /Library/Printers/Canon Remove any Canon-related files from /Library/Image Capture/Devices Reboot Install the misd-mac-ijscanner2-4_1_4-ea21_3 driver Don't install the LiDE 210 Scanner Driver Ver.18.2.0 (Mac) file, that seems to be both useless and part of the overall problem. Just use Image Capture and you should be fine.

My old iPhone 4 doesn't show up on "Find my" even when logged in (under iOS 7.1.2). The problem seems to be that it must have the "Find My iPhone" app installed, but that app didn't come with this version of iOS. To get it, you need iOS 8, which doesn't work on this iPhone. Thanks, Apple! Anyway, download this old version of iTunes , which will let you install apps. Install "Find" on iTunes, then go back to the phone and try to install it from the App Store. This will let you install the 7.0 version of the app, which will then re-enable Find, and the world will be a better place. Hey wow first post here in 12 years! I should get a prize.
