Restarting your Mac will clear any hardware glitches that are present.


Fix 1 – Change Your Connectionīefore we proceed any further with this article, make sure to restart your Mac, in order to rule out the most obvious fix. Read on to be accessing your USB drives in no time. From there, you will be able to do everything you would expect to be able to do with a USB drive: access, edit, and add to the drive.īut what if you’re connecting a drive and it’s not showing up? Is it something wrong with the drive? Or something wrong with the Mac? Well, chances are it’s not an issue with either of your devices, and there are several ways with which you can manually look up a USB-connected device on your Mac. I am considering rolling back the OS ( restore ) to an earlier time using Time Machine to see if that fixes the issue as I believe it is something that has gone wrong in the OS settings on the iMac.Īny thoughts / advice on this would be greatly appreciated.If everything is working as it should, your USB drive should appear on your Mac computer when you connect it to the USB port, either on the desktop or the Finder. However the printer is not wifi ( it’s either USB or Ethernet from the router ) so I don’t see how to use Bonjour. When I download the driver from Epson and try to install it is goes through the installation process but at the last step I get a message saying ” The installer encountered an error which caused the installation to fail.” I have contacted Epson but they just keep saying use the Bonjour connection function. Even then the system says that Apple do not have the driver for this printer.

Now it’s gone and I don’t know why? If I try to add it it does not show unless switched on. Its an Epson Stylus Pro 7880 wide format printer which was working fine using a USB connection direct to the computer. I tried your advice to add a printer that has stopped showing on my 2017 iMac ( Monterey 12.6.1 )
