Help needed: download SDR++ for the operating system of a MacBook Pro

[jhackney-spec]

I need help in downloading SDR for a MacBook Pro. I am totally befuddled. I purchased an RTL SDR V4 a few years back, to use on a MacBook Pro that is currently running a Sequoia 15.7.3 OS. At the time of this purchase, I had no problems downloading a functioning SDR++ program for my MacBook. I used my RTL SDR unit successfully for several months, but then did not have the chance to use it for the past couple of years becaus of work/health issues.d. I've just recently tried to download a current/updated zip file through GitHub (as frequently advised/directed), but can not open the downloaded zip file ((SDR++ Nightly Build (Currently 1.2.1)) because I get error messages proclaiming that "Apple could not verify “SDR++” is free of malware that may harm your Mac or compromise your privacy". I think that in the interim, the newest version involves changes to the programming that are no longer considered "safe". Can I drop back to an earlier version of the software, or is that even possible at present? I really am a rookie on this entire issue, and unfortunately get very frustrated. Is going through the GitHub process a problem? I may not even be executing the software, because I don't see an ".exe file" in the downloaded software folder. I wonder if anyone has advice on this issue? Thanks-----

@jhackney-spec you need to go to macos settings then privacy/security and allow sdr++ after you get the 'apple could not verify' message as the .app is not notarised.
You followed the correct process otherwise (grab the daily release and extract it)

Again, I thank you for your previous reply to my "problems posting". I followed your instructions as best I could but found that when I went to "privacy/security" on my Macbook (with the final update of the "Sequoya" OS", your instructional "steps" could not be followed----they didn't make sense. So, then I thought I should install the latest update of the "Tahoe OS" upgrade to see if that could be used to follow your instructions (I should have made this update several weeks ago!). But, that did no good in allowing me to follow your steps, even when I had made a fresh attempt to download the SDR++ app. There was never any automatic installation or anything along those lines. I spoke with Apple Help two different times. The second time, I was connected with the chief tech for this type of problem and, after trying a number of different strategies, he concluded that it just doesn't work. He believes that the current Mac OS versions just won't allow a download of the most recent version of the SDR++ app. He and I really tried everything possible, there is no real problem on my end, it's just that something is fundamentally wrong with the whole process for Mac users at this time. I'm not complaining, I understand that we run into these bugs periodically. I mention again that I could download and employ SDR++ on this same computer, with an earlier version of the MacOS (1-2 years ago). I appreciate your attempts to help me to this point. If you have any further suggestions, please let me know. Thanks, John Hackney
