    V2.2 has been stable for a long time...just tried to install V2.4 and although it will install into my Applications folder but it won't open and returns a "fatal memory error". Tried it with V2.5rc1 as well with the same result. I'm using OS 10.3 High Sierra which according to the notes should be ok. Anyone else having an issue?

    Thanks in advance!

    See your downloaded installation files. There is a file named ReadMe.txt included. You should read this very carefully.

    Have you done the shared memory size adjustment?

    This error is completely normal until you adjust this memory buffer via terminal. The instructions are included with the download.

    Yep, done that years ago when I started out with WSJT...that's why V2.2.2 works FB but neither of the two new versions will, both with the same memory error. Obviously it has something to do with the build of the next two versions, 2.4 and 2.5rc1. Not my first rodeo here.

    2.4 runs just fine on my M1 Mini.

    Just FYI, if you've recently done an OS update, you may have to run the fix again. I'm sure you know that, but just in case.

    Wish that were true but this High Sierra install has be in place and stable for several years...what doesn't make sense is that 2.2.2 works FB but 2.4/2.5rc1 both do not.

    Figured that was the case, but just wanted to double-check.

    At this point, I would suggest -- although I'm not really sure exactly what it would accomplish -- that you removed all WSJT-X installations from the Mac, backup and then remove the WSJT-X folder in your Library, reboot and try to install fresh. If that works, you can then copy your WSJT-X log data back into the folder so that you don't lose that. The line of thinking here is that perhaps something in that folder is causing an issue, although I think that it is unlikely.

    The ultimate solution may be to do a clean install of High Sierra and all of your applications, but that is an extreme solution that is not guaranteed to work either.

    Sorry I can't be of more help.

    You can use Applications/Utilities/ to locate your Macs crash logs. If you can find a crash log for wsjtx, those logs possibly indicate a hint at why the fatal memory error occured.

    Well, turns out you were absolutely correct...even though I'd run the Terminal scripts eons ago and V2.2.2 was working fine when I checked the shmax value it was not correct. Once I re-ran the command line the shmax was correct and V2.4 works FB. I should have listened to you before but thought that only a OS update would impact on the setting. TNX! 73 - Dino KLØS
