It stands for Null Reference Exception. It's a programming term that in plain English means that you are trying to access something that is not there when you need it. The consequences can vary from just getting log spam to a behavior in the game completely breaking.

I'll try to answer this in the clearest way possible. All robotic parts can be motorized or not by themselves, so you can have a motorized hinge without having to use a piston in-between.

You can do both, it has the option to input numbers separated by colons so you can input YY:DD:HH:MM:SS (or subsets of that from lower to higher); or you can just input a big number of seconds and the tool will translate it to UT for you.

That's the sink LED. It lights up if your vertical speed is negative and great (i.e. you're falling down fast).

Some people like to have it around to selectively restore just a few files if thing go wrong. Apple really did a number on security starting in Sierra, so it couldn't be said that the zip just works or doesn't work. It depends on a lot of thing (security settings before and after updating macOS, file system, permissions settings, etc). So the fact that it didn't quite work for you doesn't mean it won't for anyone. Anyway, I read that the installer version just works for you, so that's a win for everyone.

If you ever tried making a good old apocalyptic mission where an asteroid has a trajectory to destroy KSC and you have to prevent it, you would have realized that....you didn't need to do anything. As soon as the Asteroid entered the Kerbin atmosphere, physics were all over the place, the asteroid started behaving like a giant ball of Styrofoam flying on the wind or something weird like that. The "behavior" in this case would be the physics interactions with the atmosphere, the drag, the lift. All of these to ensure that asteroids behave the way you would expect them and get on with supervillan's agendas to destroy the KSC And well, as you can see in the GIF, now they have reentry FX and explosions, so there's also that.

On macOS there is a way to map F keys to regular function keys, this solves the problem for macOS players who can't access the Debug Menu. If you're using a non-Apple laptop there must be something similar, but you'll have to look for yourself, as there are countless possible ways this setting could be accessible.

It's perfectly normal for KSP to install without a settings file, it gets generated by KSP on loading if it's not found. If it's not being created I would advise you check if KSP has write permissions in the installation folder, you would think on Steam this is a given, but that's not always the case. Check here to find out how to repair the folder's permissions on Steam (Repair Library Folder subsection):

@Zwolff Can you upload a log from when you merely double click the KSP.app file? The log file is called KSP.log and can be found in the same folder as the KSP.app. You can upload it to pastebin or a similar website and share a link here.

Could you provide more details? What happens when you just double-click the KSP icon? What 'Show Package Contents' thing are you referring to? In all of our tests across all the macOS testbeds the team could test on, the installer just works.

KSP is sadly not compatible with screen resolutions higher than 1080p. In order to overcome this in macOS, follow these steps: 1. In the Finder, choose the KSP application so it's highlighted, but don't open it. 2. Choose Get Info from either the File menu, or right clicking 3. Place a checkmark next to "Open in Low Resolution" This will enforce KSP to natively run in 1080p resolution. BTW, this is not something KSP -specific, if you're having similar trouble with any other game or app yo can do the same thing.

We had a small delay due to a server migration, but to my understanding the bug tracker has been recently started to update again to reflect the issues we've been working on

Try switching off Surface FX, Underwater FX, Highlight FX and turning Aero FX quality to low. All of these options are in the graphics settings from the main menu.
