solved [SOLVED] Can't Install Alfred V4 or open Disk Image (is damaged and can't be opened)

[Michael Cordell]

Hi,

 

I'm trying to install V4 and whenever I download the disk image I get this message on opening:

 

"Alfred" is damaged and can't be opened. You should move it to the trash:

 

 

 

 

I've tried the following:

- Reboot

- Full shutdown and start up

- Downloading V3 and V4 (both fail in the same way)

- Installing from Homebrew

 

 

Details:

- Running MacOS Mojave 10.14.5

- "Allow apps from App Store and identified developers" in System Preferences -> Security and Privacy 

 

 

Best,

Michael

@Michael Cordell The error message mentions Chrome - Have you tried downloading it with Safari?

 

I've just double checked the download and it's fine.

Similar issue with Safari:

 

Presumably this has something to do with the code signing cert being not accepted or different on machine. Is there anyway for me to force an update on my machine?

This appears to be an issue on my end as other vendors do not work either (e.g. Google Chrome downloaded from Google) also shows a similar error. I don't think this is an alfred problem so nothing to do here.

@Michael Cordell Have you tried rebooting? I think I’ve seen this happen before with Chrome waiting to be updated but not restarted (to finish the update) for a long while. I’m suggesting a full reboot since Safari is also affected; it may be a temporary issue with Gatekeeper.

 

In the meantime, if you open a terminal and run curl 'https://cachefly.alfredapp.com/Alfred_4.0.1_1078.dmg' --output "${HOME}/Desktop/Alfred4.dmg", you should get a working DMG in your Desktop, since curl doesn’t quarantine downloads.

I am having the same issue after upgrading to Catalina. Does anybody have a solution to the issue, please?

@Anil Agrawal Have you tried deleting the file and re-downloading from https://www.alfredapp.com ? It may be that your download was incomplete and you'll just need to grab a new copy from our website
