Re: Java 9 is another example
You need to jump through the hoop, and know that it is there to even see the folder in question in Finder. That sort of stuff is hidden. I've unhidden it because I know what I'm doing and recently had to go in and take something out. This is a hand-me-down machine from my daughter and it is running a load of stuff in the background that I don't need. She is in Bioinformatics so installed a pile of custom software packages and had server connections galore which all wanted a bite.
That's right, the virus checker found something, not dangerous or active and the infected file was not something I needed. But I could not find it in Finder to delete it.
As for not being able to delete things, welcome to Android. I neither need, use or want a whole slew of the Google apps on my phone but I cannot delete them without rooting it. So why pick on Apple?
