Unity 5.4.4 F1 Asset Store stays blank in OS X Yosemite (10.10)

That’s a known problem in MacOS Serria. Please try the workaround under Yosemite. Maybe that’s the same issue.

Please look at: Asset Store gray screen in Unity (MacBook Pro; 10.12) - Questions & Answers - Unity Discussions

The workaround to access the asset store when using mac OS Sierra is to drop the tab to a single window. Than you can see the asset store. Unity or Sierra don’t support to display the asset store in the tab (embedded window).

okay so the way i got around it was to install unity via windows on my parallels virtual machine… im now able to access the assets store… sadly this isnt a solve everyone can make use of, but it worked for me.

Thanks for taking the time to get back to me guys.
