I'm new here, so apologies if I get the protocol wrong... My mac was running slowly, so I followed advice I got in other threads and ran Etrecheck. Got the following: Startup Items: ℹ️ Freecorder: Path: /Library/StartupItems/Freecorder HWNetMgr: Path: /Library/StartupItems/HWNetMgr StartOuc: Path: /Library/StartupItems/StartOuc wpa_supplicant_srv: Path: /Library/StartupItems/wpa_supplicant_srv Startup items are obsolete in OS X Yosemite Sooo - went to try and move them (as advised) and can't find the path /Library/StartupItems Went to terminal and can see the folder StartupItems. Can also get onto it - but it seems to be empty. Tried to remove the folder in Terminal but was told it didn't exist. Re-ran Etrecheck in case I had magically deleted it - got the same errors. Any ideas?
