Mac-specific issues with workarounds and fixes

Stock Support & Bug Reporting Guide

Instability/Constant Crashing [No fix, possible workarounds]

Caps lock does not enable precision controls [FIX]

Switch to Staging UI assigned to non-existent key [FIX]


Instability/Constant Crashing [No fix, possible workarounds]

Issue: KSP uses excessive RAM on some Macs, leading to frequent crashes.

Possible workarounds:

  • Reduce the Texture Quality in the Graphics settings (default is 1/2)
  • Install Active Texture Management - Aggressive version
  • Open KSP in Low Resolution (Retina displays)

  1. Go to the KSP folder in Finder
  2. Right-click/Control-click on KSP.app
  3. Click Get Info
  4. Check the box for "Open in Low Resolution"

Polls to help narrow the cause:

Caps lock does not enable precision controls [FIX] (Bug #634)

Issue: The default key for precision controls is Caps Lock, but pressing it has no effect.

Fix: Reassign precision controls to another key after starting the game: Click Settings > Input > Precision Controls Toggle, then press a key such as P or `.

Switch to Staging UI assigned to non-existent key [FIX] (Bug #2824)

Issue: This function is assigned to the Insert key, which does not exist on Mac keyboards.

Fix: After creating a backup, open the KSP_osx/settings.cfg with TextEdit and find this section:

UIMODE_STAGING
{
primary = [COLOR=#008000][B]Insert[/B][/COLOR]
secondary = None
group = 0
switchState = Any
}

Change Insert to any key that's not used for something else, such as O or Equals. Save and restart KSP.

A full list of key codes for Unity can be found here. (Thanks to SMILIE for the link)


Launcher and Patcher Issues:

Key: No fix available, Workaround, User fix, SQUAD fix

Patcher fails to update [WORKAROUND] (Bug #2844)

Issue: Patcher consistently fails to update. The KSP store update server is not currently working for anyone, though there have been OS X-specific issues in the past.

Workaround: Update KSP by downloading directly from the KSP or Steam store and installing it in a new location. Then copy your saves from the old KSP_osx/saves folder to the new installation. Update and install mods as needed.

Hey, can we sticky this? There seems to be an influx of new mac users hitting the usual bumps in the road. Be a lot easier if this was at the top of the forum, instead of all these folks putting up new threads for an old (and well known) problem.

Thanks!

re Instability/Constant Crashing [No fix, possible workarounds]

The crash appears to be caused by an error in using the GPU.  The text from a crash report is
