Unable to install v2.0.779 x64 package on MacOS

[tillig]

On trying to install the latest Git Credential Manager (v2.0.779) via Homebrew, I got the message Error - Git Credential Manager can’t be installed on this computer.

The brew output is here:

pwsh> brew install --cask git-credential-manager-core

installer: Error - Git Credential Manager can’t be installed on this computer.

Thinking it might be a Homebrew problem, I downloaded the gcm-osx-x64-2.0.779.pkg to try manually installing. I got the same error. Note it wasn't related to being blocked by the "Security & Privacy" thing - it would have popped up in there to allow me to approve it.

Thinking there may have been something mislabeled (since now the OSX package is split between x64 and ARM), I tried downloading the ARM package gcm-arm64-2.0.779.pkg. Trying to install the ARM package gave me the same error. (Was the ARM version put into both packages? 🤷 )

I went back and downloaded the 2.0.696 package, gcmcore-osx-2.0.696.pkg, and it installs just fine. There's something different between the installer there and this new one that's stopping it from getting installed.

• MacBook Pro 2019
• macOS Monterey 12.4
• Intel Core i7

I'd be happy to provide additional logging or details if you let me know where to find them.

I am getting the same error.

I downloaded latest version of XCode and Homebrew.

[objectx]

Same for me. I've downloaded gcmcore-osx-2.0.692.pkg and it works as expected. But 779 refuses to install 😢

[RobertFloor]

Same for me both with homebrew and a manual install

[mystix]

Same for me both with homebrew and a manual install

Ditto for me on an Intel Mac, macOS 12.4.

Same for me

Not working on my system as well. Hopefully, there is a fix soon.

Same error here... 2018 MacBook Pro Core i9 with macOS Monterey 12.4 (21F79)

[jellydn]

Same issue here. Just downgraded to previous version by installing pkg file, fyi https://github.com/GitCredentialManager/git-credential-manager/releases/tag/v2.0.696

[rcrooks]

Same here - tried both Homebrew and the package.

[btorsaldivar]

Same frustrating experience here with the latest version

Manually installed the previous version for now to unblock:

[GyroJoe]

The pkg seems to have the wrong xml script in it:

    <options customize="never" hostArchitectures="arm64"/>

I think the problem may be this:

Building for runtime 'osx-x64'
[51] src/osx/Installer.Mac/dist.sh: line 73: [: missing `]'

Same error here. I ran into this several days ago and tried again today to see if there had been a fix released yet. Full log from brew:

Note this fails on M1 Mac as well. Brew downloads the gcm-osx-x64-etc-etc.pkg on M1 and it also fails.

[cpach]

GCM 2.0.785 works fine on my Intel Mac. Thank you @GyroJoe and @mjcheetham!

[gojira]

I can confirm GCM 785 also works on M1 Mac. Thanks!
