Unable to empty trash can - Says Macintosh HD in use...
There are a lot of files in their, most got emptied, but all these appear to have a folder structure, with Macintosh HD with some with Library and under that again, Application Support and another folder Preferences.
I'm stuck... tried the usual googling for info, and also tried various things, but none have worked. I'm trying to get this ready for passing it on, and am currently downloading a bootable disk for High Sierra 10.13.6 - my current system. This is a 27" Mid 2010 Mac that works perfectly except this.
Any thoughts please?
