BalenaEtcher older versions give malware errors on mac and shutdown.

Old(er) versions of Balena are signed with nowadays expired certificate. That's most probably the reason why you can't run it.

BalenaEtcher older versions give malware errors on mac and shutdown.

@DJDupid "Since the new versions of balena etcher never work for flashing..." what version/platform have you tried? And what it say when "never work for flashing"? Didn't open? Didn't start flashing? Crashes? Can you try it again with freshly downloaded Balena (and for architecture you have, I mean X86 vs Arm)? The last resort, but only when you're 100% sure the app is malware free, you can open your current copy of Balena by right click->Open (only in that case it will show you button "open anyway" or so, simply the way @cgrr suggested). You can also flash image on SD card using built-in command dd (in Terminal app): https://gist.github.com/jordelver/3139365 but beware, there's no space for mistake (one single typo can delete your internal disk in your Mac). EDIT: The dd if=.... part should start rather as sudo dd if=... (you need admin privileges to direct write on disks and sudo ..., typically followed by password prompt, does the trick). It's basically the same as Balena does, just without nice coat and more intuitive disk selection.

well, in that case you should tell it sooner :-). In that time I didn't even know whether it is issue just on my printer (and few other owners) or whether it is general issue everyone fighting against. You came just with "my printer(s) doesn't do that" (which was anything but helpful). I mean, yeah, you sent something, but it wasn't an explanation of it, just some setting, some more, some less suspicious (i'd even call it "snake oil", but it sound too harsh since it helped, although in different way - I've never even tried to print 1st layer so fast as you before, so it wasn't completely useless. And for this suggestion, I thank you. It just wasn't solution for the issue, though).

and... how it helps to solve the issue with gradually expanding nozzle/hotend making the 1st layer lower and lower? Since I already found the biggest thermal expansion, the hotend (and/or its nozzle). Within first 10-15 minutes of printing it makes nozzle lower by almost 0.1mm* (at least I believe it is the main issue, 0.1mm difference is more than enough to make 1st layer ... weird). *) 0.07mm to be precise. I didn't recheck difference between nozzles, but somehow it seems the diamond CHT-ish nozzle expands as twice as much as e.g. tungsten nozzle which I measured expansion by 0.04mm (I want to recheck again, since it seems to me too big difference for the nozzle alone. Just not soon, I have other priorities at this moment)

It can be quite easily measured if you have Beacon (contact) using something like this: https://github.com/kmarty/kmarty-klipper_config_km_addons/blob/master/CHECK_THERMAL_EXPANSION.cfg (it's based on RatOS v2.1. BEACON_CALIBRATE_NOZZLE_TEMP_OFFSET except it doesn't make any changes, just prints results and it uses hotend temperature defined by you. Results is list of Z positions where nozzle "found" bed (so you have to subtract first measurement which is at the room temperature), each by one minute apart).

Nice. So, I should have made own post anyway since my issue is not by bed itself (heatsoaking of bed doesn't change it at all) and height difference in my case is about 0.1mm where I already measured that Rapido2 UHF hotend with diamond CHT(-ish) nozzle can easily expand by about 0.07mm in first 10-15minutes of printing. So in my case it is probably just to find how to easily deal with the fact that is happening.
