I have two updates on Mac-specific bugs. Windows users, now is a good time to go get another cup of coffee. Update: it looks like neither of these bugs can be fixed or bypassed within X-Plane, so they could be with us for a while. So I am adding instructions on work-arounds for Mac users.
Red Red Lines
There is a bug on recent Nvidia cards (specific to OS X) where, at high rendering settings, you’ll see a red outline around the horizon. At this point I believe that this is a driver bug.
Here’s the interesting part: this bug is fixed in the Mac drivers that Nvidia provides. (Yes – NVidia provides a driver you can run on your Mac instead of the OS X shipping one.)
Now here’s the down-side, before you go install this thing. When I used this driver, I managed to repeatedly hang my entire machine while using X-Plane. This doesn’t happen using Apple’s driver. So at this point I’d say “use at your own risk.”
(In Nvidia’s defense, the driver is targeted at after-market PCIe cards for pro users; use in a RetinaBook is “beta” and that’s what I did.)
We don’t have a work-around for the red line bug in sim – if I did, I’d have applied it. So this bug will probably be in 1040, and it will be up to you to either try the NV driver, wait for an Apple fix, or use different rendering settings.
Options for Work-Around:
- Turn down shadow settings until the artifacts go away or
- Install the Nvidia drivers and enable them in the menu bar control panel. (In the driver picker, pick OS X and you’ll find Mac after-market drivers.)
Crash Changing Planes or Quitting
Updated 11/20/15: this bug has been fixed – see here for the details.
If you get a crash when changing aircraft or quitting X-Plane, and the plane you were flying uses SASL, please don’t file a bug with me or send me a crash log. The crash is SASL crashing inside OpenAL. The crash is specific to El Capitan, and we don’t know what causes it.
This one is an area of on-going investigation; you can basically live with the annoyance of “crashing” out of every SASL aircraft or not use El Capitan. You already know how I feel about being an early adopter to new operating systems.
Options for Work-Around:
The problem is that the crash is when you unload an aircraft running SASL, so the bug appears to be “loading any plane crashes” – it’s really the unloading of the aircraft before that is causing a problem. So the work-around is:
- Launch X-Plane.
- Pick Quick Flight and enable “Show this window on every startup of X-Plane”.
- Quit X-Plane – it may crash since you are unloading a SASL aircraft.
- When you re-start X-Plane, pick the default Cessna and you will no longer be “stuck”.
If you are stuck on El Capitan and you need to fly SASL aircraft and you are seeing crashes, my suggestion is to keep Quick Flight enabled at startup. If you have Yosemite and fly SASL-enhanced aircraft, I suggest not upgrading.
