Hi again Paul, I am home and dry, about to try the uninstallation. Quick question if I may - Can you tell me which folders/files I would need to keep (or MOVE perhaps) to protect from my actual guest OS/VM being removed by uninstallation? I assume that Virtualbox VM's folder is the one, but does that contain the entire VM OS? If so I will make sure i have a second backup of that. I will read through that thread carefully before i begin. I am away tomorrow for a few days so I will leave it til i get home so I can focus and finish the job. time to uninstall VB and see if a reinstall sorts it. ![]() I have installed various apps (recent example was NoMachine, YUK, don't touch it!) and when uninstalling it left no end of remnants in my system and LittleSnitch even caught one or two processes calling home despite the entire app 'allegedly' having been removed! Sadly this is pretty common these days so I do all sorts of weird stuff to satisfy my paranoiaīut obviously that doesn't apply to VB or many other apps, though I do use AppCleaner to find files sometimes related to apps. Re AppCleaner - Yes for something like VB I would always use the official uninstaller (didn't know there was one actually!) but I do use AppCleaner sometimes, mainly to test for privacy reasons. yes my user is in staff, everyone, admin etc. E.g., you could do something similar to a thorough uninstall-&-reinstall procedure for VirtualBox Mac as outlined by former moderator socratis. So, when a dedicated uninstaller is provided with a given program, especially if it's a complex & powerful one such as VirtualBox, it's usually a good idea to use that official uninstaller instead. For instance, if a program or installer also places arbitrarily-named dynamic libraries into '/usr/local/lib/', etc., then those might not get detected and, likewise for any special configuration changes made to system databases or plists. However, note that AppCleaner can't know about every item associated with every program, and likely makes use of various heuristics such as "educated guesses" based on name or bundle identifier, which could end up missing certain items/settings. Īs to the AppCleaner utility, in general it looks like a fairly useful way to see the items associated with a given program, and/or to remove any unexpectedly lingering preferences, etc. Each group has an associated list of member users, and that's one way the system can know who's in which group and has which privileges. So, typically there's no need to change the primary group. Very nice trick for someone lacking in depth knowledge of file structures/terminal etc, like me! And yes I know with great power comes great in Unix-based systems, a user has a "primary" group but can also be a member of other groups. ![]() Note the magnifying glass, so you can click to open each file one by one. But what I found is it's a great tool for finding all remnants/files related to an app, you don't have to remove them or uninstall! There are more files for VB than I thought, I will check permissions on all of them. It's damn thorough, it catches everything. You drag an app onto the AppCleaner app icon and it pops up a dialogue asking for confirmation before deleting files. ![]() That app cleanly and fully uninstalls apps for you. I installed an app called AppCleaner (from freemacsoft i think). I don't have a lot of expertise with terminal and code, but I found a really neat workaround for finding all files related to an app, rather than guessing or (as was my approach) trawling through every single system folder one by one, very time consuming!
