v7.6.2(n) MacOS FAHControl doesn't work [Fixed]

[gunnarre]

FahClient v 7.6.20 runs, because it gives output in /Library/Application\ Support/FAHClient/log.txt but FAHControl (advanced control) v. 7.6.20 fails to start. No error messages are given, even if I start it from the command line.

OS: macOS 10.14.6
Computer: MacBook Pro (Retina, 13-inch, Mid 2014)
v. 7.6.13 works fine.

Edit: Temporary solution:

Here is a link to the 7.6.13 installer:

Can you please post the log file of V7.6.20?

What happens if you try to launch it from the command line using

Code: Select all

open -a FAHControl.app

Also, do you have VMWare installed?

[gunnarre]

Code: Select all

open -a FAHControl.app

LSOpenURLsWithRole() failed for the application /Applications/Folding@home/FAHControl.app with error -10810.

Also, do you have VMWare installed?

No

Can you please post the log file of V7.6.20?

Sure, but FAHClient runs just fine:

I do have the exact same problem. I can access the Client via telnet, but the FAHControl App doesn't start. If I run it from Spotlight, I get the following error "Das Programm „FAHControl.app“ kann nicht geöffnet werden." Sorry, this is in German, but it says, the program cannot be opened. When I double-click the app in the Finder, it starts and dies immediately without showing the UI (I briefly see the dot unter the app icon in the dock, but that's it). When I open it with the command in the thread, I get the exact same message as shown in the thread above. This is MacOS 10.15.7.

Welcome to the F@H Forum bogomir,

I am guessing that you have the same situation where FAHControl can't open but you can still run FAHClient without issues. Thanks for the report and I will notify the people involved

[PantherX]

BTW bogomir, does V7.6.13 works fine on your macOS 10.15.7 system or not (i.e. does FAHControl App starts up without any issues)?

[bogomir]

Hey PantherX, yes, the exact same thing as described by gunnarre. 7.6.13 worked fine without issues. With 7.6.20 FAHClient runs (as mentioned I can telnet into it and start/stop folding and so on.). It is only FAHControl, which seem to have issues. This is a mid 2014 MacBook Pro with 10.15.7.

[stealthswifttlk]

After casually browsing for a couple of days, I've noted a not insubstantial amount of threads/posts about installation issues for FAHControl under Linux and MacOS. I believe this is all due to the sunset of Python2 earlier this year ( https://www.python.org/doc/sunset-python-2/ ) and consequently macOS and various Linux distributions trying to push for a move forward to Python3 ( https://www.macobserver.com/analysis/ma ... languages/ )

Currently on github, there are several issues in relation to python2 dependence that could probably be closed if we deprecated the need for Python2 as a dependency. Indeed there are a couple of good pull requests that seem to have made decent headway towards this goal. This isn't a new issue, having been acknowledged all the way back in 2012 ( https://github.com/FoldingAtHome/fah-issues/issues/858 ) but I think this is something that needs addressing now or imminently as distribution maintainers seem to be actively dropping Python2 support from their maintained repositories.

I figure this will have a detrimental impact towards potential new supporters or even current supporters if they perceive they are hindered from reinstallation of FaH upon upgrading their distros. Work-arounds for installation issues should not be expected to be foisted on to end-users as this could be a potential barrier to entry or re-entry. I have seen several posts stating that the web client is not fully adequate to several end users' needs.

I saw on YouTube in the 'fireside chat' earlier this year that it was mentioned work was beginning towards an 8.0 release which will change the underlying mechanisms of FAH. Whilst I realise that this task will be taking developer time, the current release is what potential and current supporters are seeing now. Is there any way that we could get core devs to give this issue some focus?

While Python 2.7 is deprecated in the current release of macOS Catalina, and will no longer be present in the next release, that is not the problem presented in this topic. The prior 7.6.13 version of FAHControl does work. So the error causing the 7.6.20 version to not run lies somewhere else in the app than using Python 2.7. There is an open ticket already for this problem, it appears to affect macOS 10.14 and 10.15, not earlier OS versions.

FAHControl is open source - https://github.com/FoldingAtHome/fah-control. At least a couple different persons have created Python 3 based forks from that code aimed at the more recent builds of Linux that are distributed without Python 2.7, though the legacy support for it can be installed. Those proposed changes need to be reviewed before they are adopted. The current release can also be checked to see what broke between the 7.6.13 and 7.6.20 releases for macOS.

As for a new version 8 of the client, work on that was started about a year ago. The first steps were to get the existing code open sourced as much as possible. That was interrupted by the COVID response earlier this year. The project had only been able to obtain funding for a single professional programmer. A number of volunteers have come forward to work on the client, there is a Discord channel for that. When that might result in a new client being released I don't know, but expect won't be until next year sometime.

Problem persists in 7.6.21

Code: Select all

~ open -a FAHControl.app
LSOpenURLsWithRole() failed for the application /Applications/Folding@home/FAHControl.app with error -10810.

[gilbertmc]

7.6.21 fah control doesn't work either

[comixgoddess]

Same here. Downloaded 7.6.21, and could not get FAHControl to work on MacOS 10.15.7. Uninstalled and reinstalled 7.6.13, which works fine.

[StreetWill]

Where can I download an earlier version please? MacOS Catalina, FAH 7.6.21 - control won't start for me either. I could work around some little troubles before, but I can't get this version to get going at all. Thanks for your work btw
