Every time I try to start Unreal Engine 4.3.0 on my Mac I get same crash report, it worked for a while now and I can’t think of anything I’ve done that would cause this. I’m running on OS X 10.9.2. crash report is as follows:

SIGSEGV: invalid attempt to access memory at address 0x3

Has anyone had same problem or know a fix for this?

Hey ,

I’m sorry that you’re experiencing this issue. When does crash occur, specifically? Does Project Browser open? Have you updated to 4.3.1 yet? Thanks!

3

When i try to launch browser, that is when I receive crash. 4.4 preview runs just fine.

4

Try doing a Verify Install on your 4.3 build. In Library tab of Launcher, click dropdown next to 4.3 Launch option and select Verify.

5

I tried verifying install, it made no difference.

Hey ,

Could you and attach your log file for crash? You can find appropriate log file in /Users/UserName/Library/Logs/Unreal Engine/CrashReportClient. Thanks!

7

, I can’t seem to find Unreal Crash reports, there’s no unreal folder if Logs.

Getting logs from a Mac can be a bit tricky if you don’t know how. You can read our description of how to get to location here:

Specifically this part:

On a Mac, logs are located in:
/Users/UserName/Library/Logs/Unreal
Engine/(project name)Editor/
Library Folder is hidden by default.
easiest way to get to it is by
having finder active application
and while holding Option Click Go in
Mac Menu Bar. This will expose
Library.

Have you had this trouble in 4.4 after its official release?

Hey ,

I haven’t heard back from you in awhile, so I am marking this post resolved for tracking purposes. If you are still experiencing this crash after upgrading to 4.4.2, please provide information requested above. Thanks!
