We were receiving complaints from several users that they would lose the connection to their published applications when working on their Mac OS X devices. When working on these devices their published applications would suddenly be disconnected. The users would receive the following message:
- Citrix Viewer For Mac
- Cannot Start App Citrix Xenapp
- Citrix Error Cannot Start Desktop
- Cannot Start App Citrix Viewer Mac
How to troubleshoot “Cannot Start App” or “Cannot start Desktop” when launching an App or Desktop. Citrix Virtual Apps and Desktops. Comment field is. Citrix Workspace app is built on Citrix Receiver technology, and is fully backward compatible with all Citrix solutions. For the documentation of Citrix Workspace app, see Citrix Workspace app. For more information, visit the Workspace app FAQ page. Citrix Receiver for Mac provides users with self-service access to resources published on XenApp.
While investigating the issue and some Googling by my colleague Patrick de Ritter we found that we where not alone. Cedesktop.exe wince 6 download. Beside the small note Dan Brinkman already wrote about this issue there is also a nice thread about the issue on the Citrix Discussions forum. To clarify this issue I decided to write an article about this issue.
The issue the users are experiencing seemed to be caused by a new feature in OSX 10.9 called app nap. It is a sort hibernation mode for applications and causes the above described effect for users. To prevent this from happening we took the following steps:
- Select the check box at Prevent App Nap check box to prevent the application from hibernating.
Because the Citrix Receiver only handles the connection to StoreFront, you’ll also need to set this for the Citrix Viewer (previously known as the XenApp Viewer). - Use Command + I (or right-click the app, then click Get Info) to open the Get Info window.
- Open the Applications folder and find the Citrix Receiver.
- To do this, right-click the Citrix Receiver app and select Show Package Contents. Navigate to the Helpers folder, under the Contents folder, and use Command + I (or right-click the app, then click Get Info) to open the Get Info window for Citrix Viewer.
- Again, select the check box at Prevent App Nap to prevent the application from hibernating. After the user logs on again (because of the services running in the background), the application will never hibernate again for this user. That’s right, these settings are for the logged in user only.
- Besides changing the settings through the GUI it is also possible to create a script. This script can be started by the user and needs to run in the users context and is case sensitive:
defaults write com.citrix.Receiver.nomas NSAppSleepDisabled –bool TRUE
defaults write com.citrix.XenAppViewer NSAppSleepDisabled –bool TRUE
After the settings have been changed the user won’t experience disconnected sessions, caused by a hibernating application anymore. Remember the user needs to re-login before the changed settings will be effective Download mac os mojave hackintosh zone.
Please note: We tested this against Apple OS X 10.9
Is your Citrix remote desktop not launching? The excessively sophisticated makeup of a typical Citrix infrastructure can pose a big problem when troubleshooting issues. Something as seemingly uncomplicated as a Citrix remote desktop not launching can be due to a number of causes. Here are four of the most common.
Troubleshooting any issue in a Citrix environment is usually a long, drawn-out exercise that can involve several components, from a Citrix Receiver on a client all the way to your Citrix servers.
1. Unspecified Secure Ticket Authority (STA)
When your Citrix remote desktop is not launching, one of the first things you’ll want to check is whether your NetScaler Gateway has, in fact, an STA specified in NetScaler Gateway > Virtual Servers > Published Applications. Add a valid STA URL if there is none.
2. Mismatching STA Servers in NetScaler Gateway Virtual Server and Storefront
While you’re inspecting STA URLs, you might as well check whether the STA server paths specified in NetScaler Gateway match what is specified in StoreFront. This mismatch issue can be avoided right from the start by making sure the STA servers you enter in the NetScaler Gateway wizard are also entered into StoreFront (or Web Interface, if that’s what you’re using).
3. Missing Certificate on NetScaler

When a user attempts to launch a desktop from Citrix Receiver, one of the several steps involved is a Secure Sockets Layer (SSL) handshake between Receiver and NetScaler Gateway. This would require the presence of an SSL certificate on NetScaler. Because of this, you need to make sure the right digital certificate is installed there.
4. Unopened Ports as a Cause of Citrix Remote Desktop no Launching
The Citrix infrastructure involves several ports, so you need to be sure they are opened in your firewall(s). Two ports you can check when a Citrix remote desktop is not launching are port 1494 (when Session reliability is OFF) or port 2598 (when Session reliability is ON). NetScaler Gateway will need either one of these ports to be open for it to communicate with XenApp/XenDesktop servers.
5. Receiver with Non-Elevated Permissions
When you log in as a normal user to Citrix Receiver without elevated permissions, you may see the list of apps and desktops; however, you cannot launch them. And when you relaunch Citrix Receiver with administrative permissions, and then login as a regular user, Citrix Receiver launches just fine.
Citrix Viewer For Mac
To resolve this issue, ensure your account has full administrative permissions on the client machine (HKEY_USERSUSER_SIDSOFTWARECitrix). If your domain account lacks elevated permissions, back up your Registry and delete the Citrix Registry key. Next, exit the Citrix Receiver and relaunch it.
Note: You should be cautious when deleting the Registry key since the Registry Editor has its risks. Citrix can’t guarantee that issues arising from unstable OS will be solved. As such, ensure that you’ve backed up your Registry before editing it.
Avoid Citrix Remote Desktop not Launching Issues for Good
Seemingly mundane issues like a Citrix remote desktop not launching can already disrupt user productivity. Unfortunately, the sophisticated makeup of Citrix’s architecture makes it very susceptible to a lot of issues like this. If you can’t afford these downtimes, you just need to let go of Citrix altogether.
We suggest you try Parallels® Remote Application Server (RAS), a virtual application and desktop delivery solution with a more simplified architecture that makes it easy to pinpoint the root cause of any issue. That plus the fact that Parallels RAS provides precise information about any logon issue/error can save IT and users much-needed time.
