Favourites not staying in sidebar
Background: Just bought two 27" iMacs and had to install 10.9 on them as it didn't come preinstalled. Used Migration Assistant to pull the data off two TM backups (of older iMac running SL).
On both machines (some) folders we add to Favourites in the Finder Sidebar do not seem to stick. They may/may not still be there after restarting – I would say that 70% of the mornings I need to readd the missing folders back. On my machine it seems to be two specific folders and on my colleagues it is just one specific folder that keeps dissappearing. I have deleted ~/Lib/Prefs/com.apple.finder.plist & com.apple.sidebarlists.plist which doesn't seem to help.
I don't know if this is connected but also (although I don't actually use it) the "All My Files" option doesn't show. Under Finder Prefs > Sidebar the option is checked but it will not show at all even if I uncheck then recheck it? All other options hide/show when I check their check boxes.
Might there be a limit to the number of favourites you can have? I want to have 16 – which was fine on SL?
iMac, OS X Mavericks (10.9), 27" 3.2 Core i5 24GB
