Fatal Error! Support for build target platform 'standaloneosxuniversal' is not installed.

Hi,

since yesterday - or our upgrade to 5.5 - we get this error message:
Fatal Error! Support for build target platform ‘standaloneosxuniversal’ is not installed.

Windows does also not work anymore, “Failed with 13 errors” which are not visible in the change log (or not highlightet).

What is causing this? Any ETA for a fix?

Best regards

Which version of 5.5? And can you send me a link to the project so I can investigate?

The version is the 5.5f3 one. I’ll send you the details via PM.

I do get the same error plus other at random Times.
I have created a thread about it here

I’ve just had a successful build myself using Clean Build. The build after that (started from a git commit) failed. Just waiting to see if a further build is successful or not. I’m building for Mac 64, but the windows build is behaving in a similar fashion. A Clean build works ok.

Edit:
Under Config i’ve set the “Cache Library” option to false to see if builds work. Not ideal but avoids the error as far as I can tell.

For us it started working yesterday night - no one knows why. The indeterminism is high here …

Setting the Library Cache to off worked for me. but obviously my builds are now stupidly slow.

We think we may have identified the issue - a test project here for Mac 64bit is now repeatedly succeeding with an existing library cache with 5.5.0f3. If anyone continues to see problems in this scenario (5.5.0f3, Mac64, library cache enabled) please pass the word - more details to follow if that holds up.

In overnight testing and monitoring this still appears to be fixed - again, if anyone sees this error again, please weigh in.

For the curious (or anyone who runs into this error!), running Unity 5.5.0f3 on a Mac on a case-sensitive filesystem, you’ll need to symlink Unity.app/Contents/PlaybackEngines/macstandalonesupport to “MacStandaloneSupport”. If not, a first build will succeed, but reusing the library won’t work. We’re getting that addressed for future 5.5.x releases now.

I had this issue trying to open an old project in 5.5.2f1. Turns out Unity Hub had gotten the license into a confused state between the different versions of Unity I have installed (2017.x and 5.x)

Closed Unity Hub, opened Unity 5.5.2 on its own (without a project), it prompted me to sign in and put in the license key again. Then it was happy after that.

Thank you for reporting. This helped me, after I saw the error:

build target platform android could not be used

I couldn’t start an old project with 5.6.7 (installed with unity hub) - Started manual, activate license and it worked.
