does cyberghost run on os14.2.1

I have used CyberGhost for many years without major problems. Major problems came up since I have installed SONOMA on my iMac Retina 5K, 27 inch, 2019. However, today I manage to run CyberGhost doing the following:

• Start CyberGhost by hand and give it time to appear on the menu bar (color gray or white). If the CyberGhost is yellow, then it is working perfect and no further handling is required.
• Click on the gray or white symbol and choose the connection you want to use
• If CyberGhost does NOT start: go to System Settings >Network> VPN & Filters>CyberGhost VPN (IKEV2)
• Click on the information icon (the little "i" within a circle)
• Turn the switch "Connect on demand" to OFF
• Click on OK right at the bottom 

Now the CyberGhost symbol on the menu bar should turn to yellow and run perfect.

SHORTCUT:

If CyberGhost makes network problems, you should see a little banner slowly running on the menu bar. Click on that banner then click on "Open Network Settings" and proceed as mentioned above.

SUCCESS!

I have the exact same system (2019 27" iMac) and configuration (sonoma) as you and I installed the latest cyberghostvpn app and nothing (seemed to have) happened when I tried to run it. I contacted cyberghost and eventually I got a list of things to do to remove it and reinstall the app: kill (two) running processes, run keychain access (util) and remove cyberghost, run the uninstaller app (which I had already acquired), (I was also supposed to login to their website and remove my mac from the list of active devices but it was not listed. and I was supposed to have unchecked "send anonymous data" from the app's settings menu but I only did this after the new install had already seemed to be working), restart mac and download their mac app from their website. This time when I ran the app (which should have been exactly equivalent to my first install which failed) the app opened as a skinny black menu descending from the top menu bar. It's remotely possible that the initial install and run "failed" because the app opened in the background instead of the foreground so I didn't see it - but I highly doubt it. It appears the Apple system control for connecting and disconnecting the vpn (from the top menu bar icon) doesn't always work (for cyberghostvpn) and there may be some difficulty in general connecting and disconnecting this vpn but I believe it is plenty functional.

cyberghost vpn has been working good on my ipad so I'll probably keep it - but this lack of a verified app for sonoma ain't good since sonoma has been out for a long time.

Uninstall it.

http://www.reggieashworth.com/appdelete.html offers uninstallation when the software in question doesn't have its own uninstaller.

The only reason to use a VPN is:

1. To access a company/school network securely. In which case the company/school will provide the compatible VPN software.
2. To access a site in a foreign country that doesn't allow your country to access it. This may cause copyright law violations. Given the rules of this board, we can't give help on such scenarios.
3. To access websites that are blocked by a network interruption. When the VPN isn't running, you can run traceroute to the domain name or IP of the website in question and if the traceroute reveals nothing but asterixes before reaching the domain/IP of where you are visiting, you may find an alternate route if you know an open path down a different route to another host that is happy to let you use them.

Mac OS has its own VPN setup:

Set up a VPN connection on Mac - Apple Support

You can't run two VPNs simultaneously on a Mac, unless the second VPN is in an isolated virtual host like Parallels, VMWare, or Virtualbox.

Your best option is to contact support and ask…

The Cyberghost iPhone App from the Appstore on the Mac is running smoothly. It's not the best option, but it is a well working workaround.

I have installed CyberGhost on my iPad and on my iPhone for many years now. Usually CyberGhost runs quite smoothly. On the iPad you can always see if CyberGhost is active since "VPN" appears on the upper right corner. Careful you have to be with your iPhone since there the remark "VPN" does not always appear. For your security, use CyberGhost whenever you use an external WLAN.

You're welcome. Some companies are slower than others.
