open any project would pop a lot of assertion failure as:
Assertion failed: Failed to change file flags for ‘/Applications/Unity/Unity.app/Contents/Resources/PackageManager/Editor/com.unity.modules.accessibility/package.json.meta’. errno: 13
scene can play normally, however not able to build!
And the download assistant always failed to fetch the installer in the middle! Very frustrated experience on unity for MAC!!
Well, Problem solved after I manually deleted the Vuforia folder inside unity program!
Hi tufeixp, the packman team is aware of the issue and it should be fixed in 2018.1.0b3.
I have the same problem for many packages in beta 4
Assertion failed: Failed to change file flags for ‘/Applications/Unity/Unity.app/Contents/Resources/PackageManager/Editor/com.unity.modules.accessibility/package.json.meta’. errno: 13
… for all other packages…
Assertion failed: Failed to change file flags for ‘/Applications/Unity/Unity.app/Contents/Resources/PackageManager/Editor/com.unity.modules.xr/package.json.meta’. errno: 13
same problem. macbook air latest version
The implementation of this fix took a little longer. It is going to be in b5.
I have had this problem. For me one solution was to run Unity first as super-user:
sudo /Applications/Unity/Unity.app/Contents/MacOS/Unity
After that it works fine in normal mode.
Another workaround is to change the owner of the files in /Applications/Unity/Unity.app/Contents/Resources/PackageManager/Editor/ to your current user. But this is hopefully fixed with b5 as mentioned earlier.
The fix for this is in b5 (just released) as Leonhard mentioned. However it seems to have been omitted from the release notes - looking to get that addressed.
