This is just a quick post about an issue you’ll see when installing VMware Fusion on macOS High Sierra.
During the install the following screen pops up.
As you’ll have to dismiss that screen for continuing I figured it might be helpful to give quick directions.
The “Security & Privacy System” preferences can be found in the system preferences (apple menu -> system preferences)
Just select that one and you’ll get the screen that the popup was telling you about.
Now click the Allow button here and you’re all set.
Update 2017/10/03 Sometimes it turns out that the button does not show up. You get error “Cannot find a valid peer process to connect to” but no way to fix it. Turns out that there was a smart cookie that managed to figure this one out. See: https://communities.vmware.com/message/2708220#2708220
In short: You can trigger the confirmation by moving the Fusion install to another folder -while using Finder- and then back into the Applications folder.
Another reason for not being able to install is if gatekeeper has quarantined the downloaded installer. You can find out via the command line. Assuming your files are downloaded to the normal download folder, running the following commands using terminal:
xattr -l ~/Downloads/VMware-Fusion-10.0.1-6754183.dmg xattr -dr com.apple.quarantine ~/Downloads/VMware-Fusion-10.0.1-6754183.dmg
The first command xattr -l lists the .dmg file extended attributes and the command xattr -dr removes the quarantine flags (-d = delete -r = do for all files within the dmg)
After doing that rerun the installer to install VMware Fusion again.
