Horizon Client 4.8 on macOS Mojave 10.4 black screen?

Mackopes Jun 8, 2018 11:28 AM

I'm testing macOS Mojave Beta 1, and while the Horizon Client connects fine, it's just a black screen (PCoIP OR Blast).

Anyone else successfully test this config?

Thanks!

Just a bit more detail. Same issue with Horizon Client 4.7. (thought I would try downgrading just in case)..
Works fine with the Horizon HTML Access.

Does it eventually timeout and disconnect? A black screen typically means a communication/firewall issue.

I'm having the same issue. I've let it sit there for about 10 minutes and it just stays black screen. Allowed Horizon thru the mac firewall. Horizon admin is showing as connected.

Have you tried clicking in the Horizon Client window? I see this on the Horizon Client for Mac with Windows 10 agents where the screen is black until you pass keyboard/mouse input to it.

I have, doesn't ever seem to show. But it does look like the input is making it to the machine. If I remote view the virtual machine from my windows desktop I can see the mouse and keyboard inputs I'm doing on the mac.

This is a similar issue that happens every year with various iOS apps and the iOS betas (obviously not the Mac, but the situation is the same). VMware can't update their app to fix the issue because the next OS beta might have a fix for it and chasing bugs/issues on a beta OS is fruitless effort until the gold master is available and the code is finalized. I wouldn't expect any fixes until then (judging on past releases, sometime in September). Would be interesting to see if a new beta version fixes the issue without any changes from VMware. I've seen this on a number of iOS apps, so it's not entirely out of the question.

Makes sense. Can't blame them. Thanks for the info!

Speaking of a new build, looks like Apple released 10.14 Mojave Beta 2: https://9to5mac.com/2018/06/19/macos-mojave-beta-2/

Can you try it and see if it fixes the issue? I'll take a guess that it doesn't, but it's worth a try.

Yea, been having the same issue here with the black screen in Mojave. I have put in a bug report to Apple about it. Please do the same if you have the ability to do so.

Can confirm that the same still happens on MacOS 10.14 Beta 3.

Although who's to say that it's an apple issue, and not the way that VMWare has hooked into the system to display the VDI desktops?

After all - RDP client works OK, and that does pretty much the same thing...

I can also confirm, it has not worked for me on Mojave since using the beta 1, 2 or 3 today.
Also downgraded to 4.7 just in case, still no go. I am just trying to be patient

Just for the record, doesn't work with iOS 12 beta 3 either..

I would suspect that apple have added an extra security layer that Horizon clients were bypassing, and this is what's causing the issue - similar things happened with macOS 10.11 and VMWare eventually updated the client to work - version 3.4.1 was released with the release note.

When you connected to a remote desktop from a Mac OS X El Capitan (10.11) client system, the entire desktop window was black. This issue has been resolved.
