Hello,

It seems I'm not the only macOS user struggling to get LOGOComfort working on macOS. So far, I hadn't seen macOS 15 (Sequoia) listed in the forum, so I'm writing up my steps to get it installed and working. FYI, I'm using a MacBook Pro with an Intel chip.

Most information is gathered from the following two threads:

• How to install LogoSoft on new Mac?
• Soft Comfort 8.4 upgrade of macOS

Java Virtual Machines

The installer requires Java 8, while the LOGOComfort app itself needs Java 11. The Amazon Corretto editions of these Java Virtual Machines work fine.

Manual installation according the Amazon documentation:

• Install Amazon Corretto 8
• Install Amazon Corretto 11

open Setup.app

The installer should run ok. As my previous version, I had the files from an archived Logo Comfort 7 CD on my NAS and pointed it to the path "Mac/Application(Mac 10.5 or later)" which was accepted by the installer as my previous version.

Complete the installation process.

Run the LOGOComfort app

This needs to run using Java 11. Similar to the installer, we must first set the correct Java version. From a shell, run this:

export JAVA_VERSION=11
cd <path-where-you-installed-logo-comfort>
open LOGOComfort.app

Replace "path-where-you-installed-logo-comfort" with the actual folder where you installed the app. This should now launch the app correctly.

Hope this helps other users on macOS.

And if employees of Siemens are reading this, can you please advocate internally to get this antiquated application modernized for macOS?

Hi Ringo,

Thank you so much for this.  I had to make a couple of corrections to the above to get it to work:

1. For setting the Java version for the installer, amazon-corretto-8.jdk should be referenced instead of amazon-corretto-11.jdk

export JAVA_HOME=/Library/Java/JavaVirtualMachines/amazon-corretto-8.jdk/Contents/Home
java -version

2. For removing the quarantine on InstData, the preceding directory change should not include the InstData folder: 

cd ~/Downloads/Web_Installers/LOGO! Comfort/InstData
xattr -r -d com.apple.quarantine InstData

 3. For me, open Setup.app still goes to the damaged file warning.  I was only able to run Setup by navigating in Finder and Control + Clicking the file and selecting Open (while continuing to hold Control). I still get the damaged file warning, but this way I get an "Open" button that allows me to bypass it.

Thanks again!

Hi Ringo and AutoGen_2202498.

There could be a confusion here for those that did not catch the little subtlety.  There are two versions of Corretto Java that are involved.  Corretto-8 is required to run the Setup that installs the update to LSC 8.4 and Coretto-11 is required to run LSC 8.4 itself, once it is installed.

If Corretto-8 is not needed for any other application (like LSC 8.3), I would suggest to uninstall it and keep only Coretto-11.  This is what I did, and this works fine.

I tried to follow described steps, but when I try to open the Setup.app it still shows me that app is broken even when I open that in terminal and Finder. Does anybody has skills how to install that in that case?

Second this, I followed all steps and still getting file damaged. Note: MAC is not and intel processor.

I had a similar problem on macOS 14, that was resolved with the help of others at the time.  Here are the points I would suggest to check.  Note that the details are also found on the top of this discussion.

• the downloaded file has some problems inside.  When it auto unzips, there are missing execution permissions with a file named Setup inside Setup.app, which gives an error "Unable to open Setup".  This could be corrected manually with "chmod", or if the downloaded file is unzipped with a third party application like "TheUnarchiver" (free, from MacPaw).

• next, you may have an error "Unable to open Setup, because it is damaged", and this is because Setup.app is not signed.  The damage is corrected by removing Setup.app from quarantine with "xattr -d", and you may have to Control-click on Setup.app to force it to open.

• now, the Setup.app has to run using Corretto 8, and this only to install LSC 8.4

• once installed, Corretto 8 is not required any more, but Corretto 11 has to be installed to run LSC 8.4.  Use the Intel x64 version, not the aarch64 version.  I noticed that Oracle JDK 11 does work, but we are getting some errors in some menu functions (like menu -> Properties).

• if you want to be able to still run LSC 8.3, you need to have to keep Corretto 8 installed and find a way to manage which version of LSC is using which version of Coretto.

Note: I did the installation on both M2 MacBook and i9 iMac; they run today macOS 15

Hi AlanTrollip.

As per my notes that I wrote last year, this trick is something you have to do on macOS 13, to allow the Setup to execute.  On macOS 11 and 14, it doesn't seem to be required (and the macOS doesn't ask for it, at least, not for me).  I don't know about macOS 12, since I haven't tried the installation on this macOS version.
