    I have a Macbook Air 2013 13" which is getting a bit slow. Will a clean install make a difference? And what are important things to think about when doing a clean install (apart from the obvious issue of back up)?

    Advice much appreciated.

    Hard to answer with so little information. Could you provide details such as installed software, is the SSD full/ in good condition etc.

    One option is to download and run Etrecheck, it will give diagnostic information about your Mac which might provide clues to why the Macbook Air is slow.

    I had to search for it also. Looks like some kind of virtual network kext extension.

    OP > I don't think in all my time on this forum I have ever seen an Etrecheck report showing more launch and startup items running on one Mac. :eek:

    Any of them, or a combination of them, may be causing your slowdowns. There is no magic or easy way to tell which item on the report is causing the issue.

    Just as a test, reboot to safe mode by holding the shift key at startup. That will prevent all those launch and startup items from running. Does that help with the problem? If it does, then you need to start removing those items until you find the culprit.

    A clean install of course would get rid off all of these as long as you don't turn around and install them back.

    OP:

    I agree with Weaselboy, problem is likely one of the launch/ startup items or the combination.

    Try safe boot first, if it helps the problem is very likely one of the launch/ startup items.

    If safe boot has no effect then the problem lies elsewhere.

    Awesome, thanks so much, everybody. I did a safe mode restart and there was a MASSIVE difference. So taking my cue from this...

    :oops: ...I've been deleting just about everything in those folders, including the tap & tun as it's not needed for my current VPN, and cleaned up the list of apps that start on log in. After a re-start, it all seems a whole lot better - that's just a first impression at the moment, but looks positive.

    Thanks a lot :)
