Greetings, my problem is that external drives and usbs do not appear on desktop when connected, they only appear after I open disk utility and click on Verify in First Aid. No problems after that, but I'm wondering what is causing this. I'm on a late 2013 iMac OSX Yosemite 10.10.5. Had no issues until a week ago.

How are these USB external drives formatted..?
Are these external drives also being used with a newer Mac or PC...?
If your sure that you have a Late 2013 iMac.
see > Identify your iMac model - Apple Support
It can be upgraded from Yosemite 10.10 to Catalina 10.15.

Hi,
Try to check your iMac with Apple Diagnostics if it's caused by hardware related issue.

Hi den.thed, the external drives are formatted for mac, and I occasionally also use them with a 2017 imac. usb sticks I use on both mac and pc. Have had no problems with either until now. I was warned against upgrading from Yosemite because of compatibility issues with the version of pro tools I use, so I'm wary of attempting that. I'm in the process of setting up a mac mini which will no doubt resolve these issues, just need to keep using the imac for the time being on a current music project.
Many thanks kaz-k, I'll give that a try.
